Calling `start()` afterwards will resume from where it left off. + +### stop() + +Stop the animation. After calling this, the next call to `start()` will start at the beginning. + +### reset() + +Move the timer back to the beginning, so the animation starts over. This can be called either when the animation is currently running or when it is paused. + +### setProgress(position, units) + +Change the position of the animation. This allows random access to any place in the tune. + +If the second parameter is not present, then `units` equals "percent". The possible values are: + +* `"percent"`: The percent passed in is a number between 0 and 1. This can be called either when the animation is currently running or when it is paused. + +* `"seconds"`: The seconds from the beginning of the tune. If this is passed the end of the tune it is changed to the end. + +* `"beats"`: The beats from the beginning of the tune. If this is passed the end of the tune it is changed to the end. + +### replaceTarget(visualObj) + +If the underlying music changes on the fly, this replaces the current object without having to destroy the object and start over. `visualObj` is the return value from `renderAbc`. + +## Example + +Paste in any ABC you want here then click "start" to see what is returned by the timing callbacks: + + + + + + diff --git a/docs/audio/synthesized-sound.md b/docs/audio/synthesized-sound.md new file mode 100644 index 0000000000000000000000000000000000000000..d6cd29fd704d1fd4ea56d8eca58b1c1494afee14 --- /dev/null +++ b/docs/audio/synthesized-sound.md @@ -0,0 +1,671 @@ +# Synthesized Sound + +## Browser Compatibility and Requirements + +* This works in any browser that supports `AudioContext`, `AudioContext.resume`, and `Promises`. That does NOT include IE, but this will work on any other "modern" browser that is at least the following version: Firefox 40, Safari 9.1, Edge 13, and Chrome 43. + +* This requires an internet connection for the "sound fonts". You can supply your own sound fonts, so if you want to deliver them locally you can get by without the network. The default sound fonts come from [this github repo](https://paulrosen.github.io/midi-js-soundfonts/abcjs). + +* It is theoretically possible to create complex enough pieces to bog down your browser or eat up memory. The two things that take resources are each unique note in each instrument and the overall length of the music. Music of a few minutes long with a variety of notes in a few different instruments work with no problem on all devices that have been tested. + +## Theory + +* This creates an audio buffer that is similar to a WAV file and contains the entire piece to play. + +* The sounds themselves come from a "sound font": that is, each individual note on each instrument is a separate sound file that is combined into the audio buffer. + +* The instrument numbers and the pitch numbers come from the MIDI spec. MIDI is not normally produced, but it is MIDI-like. (There is a function to create a MIDI file for download.) + +## Examples + +See [Basic Synth](https://raw.githubusercontent.com/paulrosen/abcjs/main/examples/basic-synth.html) for the simplest possible way of making sound. + +See [Full Synth](https://raw.githubusercontent.com/paulrosen/abcjs/main/examples/full-synth.html) for an example that incorporates a bouncing-ball type animation and an audio control. + +## API + +Since there are a number of ways to use the synthesized sound: with or without a visual depiction of the tune, with or without a user-facing audio control, and with or without various timing callbacks, there are a number of different entry points. + +## CreateSynth + +Creates the object that caches and buffers the audio to be played. All implementations of audio playback will need a CreateSynth. + +```javascript +var synth = new ABCJS.synth.CreateSynth(); +``` + +### init(synthOptions) + +The first call that must be made on the CreateSynth object. This will load all of the needed notes and will return a promise when they are loaded. There might be a considerable delay for this to finish. Because the notes are cached, though, the second time CreateSynth is created with a piece of music with similar notes, it will take much less time. See below for the synthOptions. + +This must not be called until the user has made a gesture on the page because this references an `AudioContext`. + +This returns a promise after all the notes have been loaded. The promise contains: +``` +{ + cached: [], // an array of the notes that were previously loaded. + error: [], // an array of the notes that haven't been loaded and the error message that was received + loaded: [] // an array of the notes that have been loaded. +} +``` + +#### synthOptions + +| Attribute | Default | Description | +| ------------- | ----------- |----------- | +| audioContext | undefined | This the value of `new AudioContext()`. It should be passed in instead of created because the calling program might be managing and reusing this. It also MUST be creating in the handler of a user action. It can't be created at any other time. But if you don't pass one in then abcjs will create it. This value is cached for the length of the browser session. | +| visualObj | undefined | This is the result of `renderAbc()`. Important: `renderAbc()` returns an array, since an ABC string can contain more than one tune. This variable is just one element in that array. Either this must be supplied, or `sequence` must be supplied. | +| sequence | undefined | This is a manually-created set of instructions for creating the audio. It is built using the `SynthSequence` object. | +| millisecondsPerMeasure | calculated | This allows control over the tempo. If this is present, then the tempo specified in the ABC string is ignored. | +| debugCallback | undefined | This will be called with various extra info at different times in the process. | +| options | undefined | Some options for the sound creation (see list below). | + +#### synthOptions.options + +In addition to the following option, you can also set the options described in audioParams below. + +| Attribute | Default | Description | +| ------------- | ----------- |----------- | +| soundFontUrl | "https://paulrosen.github.io/midi-js-soundfonts/abcjs/" | This is the public URL for the sound font. If it isn't present, then the sound fonts come from the github repo. This can be replaced if the new sound font follows the same format. | +| soundFontVolumeMultiplier | 1.0 | This is the amount to multiply all the volumes to compensate for different volume soundfonts. If you find that either the volume is too low or the output is clipped, you can experiment with this number. | +| programOffsets | {} | The offset of each voice to the beat. Some voices have a ramp up time so that the beginning of the sound isn't the beat. This is the number of milliseconds that the program should be offset. This is expressed as `{ 'program_name': 100 }` where the program name is one of the standard midi names, like "acoustic_grand_piano". If you use the default soundfont then these values are set automatically. You can still provide this parameter to override the settings if you like. | +| fadeLength | 200 | The number of milliseconds to fade out each note after its has played for the correct length. The gain will go from 100% to 0% in this number of milliseconds. | +| sequenceCallback | undefined | This is called after the array of notes is created, and just before it is used to create the audio buffer. The array of tracks is passed in, and this gives a chance to tweak the audio before it is created: you can give it some swing, you can change volumes, or anything else. | +| callbackContext | undefined | This is passed back when the sequenceCallback function is called. | +| onEnded | undefined | This function is called after the playback stops. | +| pan | [0...] | An array of numbers between -1 and 1 for how far to pan each track. -1 is all the way to the left and 1 is all the way to the right. If there are not enough items in the array for all the tracks, then the remaining tracks will be in the middle. | + +#### Example +```javascript +var myContext = new AudioContext(); +var visualObj = ABCJS.renderAbc(...); +synth.init({ + audioContext: myContext, + visualObj: visualObj[0], + millisecondsPerMeasure: 500, + options: { + soundFontUrl: "https:/path/to/soundfont/folder", + pan: [ -0.3, 0.3 ] + } +}).then(function (results) { + // Ready to play. The results are details about what was loaded. +}).catch(function (reason) { + console.log(reason) +}); +``` + +The above will: +1. create audio for the first tune found in the tunebook that is passed to `renderAbc`. +2. It will play at 1/2 second per measure (180 bpm for 2/4 time). +3. It will use the URL provided for the soundfont. +4. It will put the first track a little bit to the left side and the second track a little bit to the right. (Note that if the music is a single line of music with chord diagrams, the melody will be track 0 and the chords will be track 1.) + +### prime() + +This creates the actual buffer - it doesn't require a network connection since all the notes have now been preloaded. It returns a promise because there might be a little bit of time delay doing the calculations. + +After calling this, everything is setup so you can freely call the rest of the functions to control how the audio works. + +This returns a promise that is `{ status: audioContextStatus, duration: lengthInSecondsOfAudio }` + +Note that normally the status will be "running". On iOS, though, it can sometimes be either "suspended" or "interrupted". It might require user intervention to resolve this. + +#### Example +```javascript +synth.init(...).then(() => { + synth.prime().then((response) => { + console.log(response.status) + ... + }); +}); +``` + +### start() + +This starts the audio. + +Call this after `prime()` has returned its promise. This will happen fast and doesn't have any latency, so you can call this right as you are timing other things to be in sync with the audio. + +### pause() and resume() + +After `start()` has been called, pause and resume can be called to control the playback. + +### seek(percent, units) + +This changes the playback position. It can be called whether the sound is currently playing or not. + +If the second parameter is not present, then `units` equals "percent". The possible values are: + +* `"percent"`: The percent passed in is a number between 0 and 1. This can be called either when the animation is currently running or when it is paused. + +* `"seconds"`: The seconds from the beginning of the tune. If this is passed the end of the tune it is changed to the end. + +* `"beats"`: The beats from the beginning of the tune. If this is passed the end of the tune it is changed to the end. + +### stop() + +Stops playing the sound and resets the progress to the beginning of the sound file. + +### download() + +This returns the audio buffer created. (It is in WAV format.) + +### getAudioBuffer() + +This returns the AudioBuffer that was created in the the `prime()` call. + +## SynthController + +Creates a visual widget that allows the user to control playback, including play and stop buttons, a progress bar, etc. This is the quickest way to set up a playback widget. See the section below for options. + +The constructor can be called at any time, including before much is initialized: + +```javascript +var synthControl = new ABCJS.synth.SynthController(); +``` + +### load(selector, cursorControl, visualOptions) + +After the DOM is loaded, this should be called to initialize the visual widget that contains the "play", etc. buttons. + +While this can be called multiple times, it is generally just called once during initialization. + +#### selector + +This is a CSS-style selector of the element that should be turned into the audio control. + +#### cursorControl + +This is an optional object that can be passed in that will receive callbacks when events happen that should move the cursor. See the section on "CursorControl" for more info. + +#### visualOptions + +This is a hash with the following possible properties: + +| Option | Default | Description | +|---|---|---| +| displayLoop | false | Whether to display a button that the user can press to make the tune loop instead of stopping when it gets to the end. | +| displayRestart | false | Whether to display a button that the user can press to make the tune go back to the beginning. | +| displayPlay | true | Whether to display a button that the user can press to make the tune start playing. (Note: this turns into the "pause" button when the tune is playing.) | +| displayProgress | true | Whether to display the progress slider. The user can click anywhere on this to get the music to jump to that location. | +| displayWarp | false | Whether to display the tempo and allow the user to change it on the fly. | + +### disable(isDisabled) + +This is called internally when waiting for the audio to finish loading. It can also be called directly by the client. The most common use for that is to disable the visual control when you are about to load in a new tune. + +If you load in a new tune without disabling the control first and the user clicks play while the notes are still being loaded over the network, the old tune will play until the new one is ready. + +### setTune(visualObj, userAction, audioParams) + +This is called whenever there is a new tune ready to be loaded into the player. + +#### visualObj + +This is one of the tunes that is returned from the `renderAbc()` call. That is, `renderAbc` will return an array of tunes. Often it is an array of length 1 if there is only one tune in the abc string, but it could be multiple tunes. + +#### userAction + +True if this is being called inside an event handler from a user gesture. The audio buffer can't be created until then. If this is `true`, then the audio buffer is created immediately. If this is `false` then the audio buffer is not created until the user clicks the `play` button. + +### audioParams + +Here are the possible properties that can be passed in: + +| Property | Default | Description | +|---|---|---| +| audioContext | create it. | An AudioContext object so that they can be reused. | +| debugCallback; | null | A function that is called at various times in the creation of the audio. | +| soundFontUrl | use the default | The publicly available URL of the soundfont to use. | +| soundFontVolumeMultiplier | 1.0 | This is the amount to multiply all the volumes to compensate for different volume soundfonts. If you find that either the volume is too low or the output is clipped, you can experiment with this number. | +| millisecondsPerMeasure | calculated | An override of the tempo in the tune. | +| visualObj | null | The object returned from `renderAbc`. | +| options | {} | Options to pass to the low-level buffer creation routines. | +| sequence | null | An alternate audio specification, if visualObj is not present. | +| onEnded | null | A callback function when the AudioBuffer finishes playing. | + +The `options` element above can have the following properties: + +| Property | Default | Description | +|---|---|---| +| sequenceCallback | null | A hook to get the instructions that will be passed to the Audio Buffer. This can be used either to debug what audio was generated or to modify the sequence before the audio is created. This can be useful to add "swing" to the beats, or do any other processing that isn't possible in ABC notation. | +| callbackContext | null | This is passed back with the sequenceCallback. It can be anything you want. | +| program | 0 | The midi program (aka "instrument") to use, if not specified in ABC string. | +| midiTranspose | 0 | The number of half-steps to transpose everything, if not specified in ABC string. | +| channel | 0 | The "midi channel" to use. This isn't particularly useful except that specifying channel 10 means to use the percussion sounds. | +| drum | null | Whether to add a drum (or metronome) track. A string formatted like the `%%MIDI drum` specification. Using this parameter also implies `%%MIDI drumon` See the section for "Drum Parameter" for an explanation. | +| drumBars | 1 | How many bars to spread the drum pattern over. See the section for "Drum Parameter" for an explanation. | +| drumIntro | 0 | The number of measures of count in beats before the music starts. | +| drumOff | false | If you want a metronome only for the intro measures but not when the tune starts, use this along with the `drumIntro` and `drum` params. This has no effect if either one of those is missing. | +| qpm | null | The tempo to use. This overrides a tempo that is in the tune. | +| defaultQpm | null | The tempo to use, only if there is no tempo in the tune. | +| chordsOff | false | If true, then don't turn the guitar chord symbols into sound. (But do play the metronome if there is one.) | +| voicesOff | false | If true, play the metronome and accompaniment; do the animation callbacks, but don't play any melody lines. This can also be an array of voices to turn off. The voices are numbered starting at zero. | +| detuneOctave | 0 | The number of cents to raise the pitch of the top note of an octave that is played at the same time. That is, in multipart music, if the tenor and soprano parts are an octave apart the soprano note gets lost in the overtones. Making the top note slightly sharp brings it out without making it sound out of tune. | + +### play(), pause(), toggleLoop(), restart(), setProgress(ev) + +These do the same thing as the user pressing these buttons, but can be called programmatically. + +### setWarp(percent) + +This changes the tempo to the percent passed in. That should be a positive integer. It will change the tempo immediately if the music is already playing. + +### download(fileName) + +This will download the current audio buffer as a WAV file to the fileName passed in. + +### Example + +The following creates an audio control that the user can manipulate. + +```javascript +// given that there are two elements in the DOM with the IDs "paper" and "audio" +var cursorControl = { ... }; // see section on CursorControl +var abc = "X:1\n etc..."; +var abcOptions = { add_classes: true }; +var audioParams = { chordsOff: true }; + +if (ABCJS.synth.supportsAudio()) { + var synthControl = new ABCJS.synth.SynthController(); + synthControl.load("#audio", + cursorControl, + { + displayLoop: true, + displayRestart: true, + displayPlay: true, + displayProgress: true, + displayWarp: true + } + ); + + var visualObj = ABCJS.renderAbc("paper", + abc, abcOptions); + var createSynth = new ABCJS.synth.CreateSynth(); + createSynth.init({ visualObj: visualObj[0] }).then(function () { + synthControl.setTune(visualObj[0], false, audioParams).then(function () { + console.log("Audio successfully loaded.") + }).catch(function (error) { + console.warn("Audio problem:", error); + }); + }).catch(function (error) { + console.warn("Audio problem:", error); + }); +} else { + document.querySelector("#audio").innerHTML = + "Audio is not supported in this browser."; + } +} +``` + +## getMidiFile(source, options) + +This is called to get the audio in MIDI format, instead of as a playable audio buffer. + +```javascript +ABCJS.synth.getMidiFile(source, { midiOutputType: 'binary', bpm: 100 }) +``` + +### source + +Either the ABC string to create the MIDI from or the object that is returned from `renderAbc`. +Note that `renderAbc` returns an array, so to get the first tune, for instance, you need to use `[0]`. +When using the object many of the options passed in are ignored because the tune is already created. + +### options + +The same options as are used elsewhere, with the addition of: + +```javascript +options = { + midiOutputType: "encoded" | "binary" | "link", + // The following OPTIONAL parameters are only used when the type is "link": + downloadClass: "class-name-to-add", + preTextDownload: "text that appears before the link", + downloadLabel: function() | "the text that appears as the body of the anchor tag that is clickable", + postTextDownload: "text that appears after the link", + fileName: "the name of the file that the midi will be saved as" +} +``` +Note that `downloadLabel` can be either a string or a function that is passed the tune object and the tune index. +The return of that function must be a string. If downloadLabel is text and contains `%T` then that is replaced by the tune's title. + +#### midiOutputType + +If this is not present or set to `link`, then the return value is a link that can be placed directly on the page for the user to download. + +If this is set to `binary`, then the actual contents of the midi file are returned, as a blob. + +If this is set to "encoded", then the contents of the midi file are returned, as an encoded ASCII string. That is, bytes are represented by `%xx` where xx is a hexidecimal value. + +#### downloadLabel + +If this isn't present, then the title is retrieved from the tune and the label is "Download MIDI for $TITLE". + +If you'd like to use the title in the label but modify it, use `%T`. That is: `downloadLabel: "the tune %T is ready for download"` + +### Examples + +#### Complete download link + +```html + +``` + +```javascript +var midi = ABCJS.synth.getMidiFile("X:1\nT:Cooley's\netc...", { chordsOff: true, midiOutputType: "link" }); +document.getElementById("midi-link").innerHTML = midi; +``` +That results in the following html: + +```html + +``` + +#### The midi data for your own download + +```html +MIDI +``` + +```javascript +var midi = ABCJS.synth.getMidiFile("X:1\nT:Cooley's\netc...", { chordsOff: true, midiOutputType: "encoded" }); +document.getElementById("midi-link").setAttribute("html", midi); +``` + +#### Actual midi file to pass to another library + +```javascript +var midi = ABCJS.synth.getMidiFile("X:1\nT:Cooley's\netc...", { chordsOff: true, midiOutputType: "binary" }); +otherLibraryMidiPlayer.loadTune(midi); +``` + +#### Passing an object + +If you already have parsed the tune you can just pass it in: +```javascript +var visualObj = ABCJS.renderAbc("paper", "X:1\nT:Cooley's\netc..."); +var midi = ABCJS.synth.getMidiFile(visualObj[0], { midiOutputType: "encoded" }); +``` + +## CreateSynthControl + +Lower level object than `SynthController` if you want the functionality without the visible control. + +```javascript +var control = new ABCJS.synth.CreateSynthControl(element, options); +``` + +`element` is either a string representing a selector of an existing element on the page or a DOM element. The contents of that element are replaced with an audio control. + +### options parameter + +| Option | Description | +| ------------- | ------------- | +| loopHandler | Callback function when the loop button is clicked. If this is not present, then the loop button is not displayed. | +| restartHandler | Callback function when the restart button is clicked. if this is not present, then the restart button is not displayed. | +| playHandler or playPromiseHandler | Callback function when the play button is clicked. if this is not present, then the play button is not displayed. If the `handler` version is present, then it must return a promise. | +| progressHandler | Callback function when the progress bar is clicked. if this is not present, then the progress bar is not displayed.| +| warpHandler | Callback function when the warp percent is changed. if this is not present, then the warp percent is not displayed. | +| afterResume | Callback function after the AudioContext is set up correctly. | +| ------------- | ------------- | +| hasClock | Whether to display a clock on the control. | +| ac | The AudioContext to use for this control. (Optional - if this is not present, then a button will appear asking the user to click to get an AudioContext.) | +| ------------- | ------------- | +| repeatTitle | To override the text of the tooltip for toggling loop mode. | +| repeatAria | To override the text of the aria for loop mode. (By default, the repeatTitle is used.) | +| restartTitle | To override the text of the tooltip for the restart button. | +| restartAria | To override the text of the aria for restart mode. (By default, the restartTitle is used.) | +| playTitle | To override the text of the tooltip for the play/pause button. | +| playAria | To override the text of the aria for the play/pause. (By default, the playTitle is used.)| +| randomTitle | To override the text of the tooltip for the progress slider. | +| randomAria | To override the text of the aria for progress slider. (By default, the randomTitle is used.)| +| warpTitle | To override the text of the tooltip for the warp input. | +| warpAria | To override the text of the aria for warp input. (By default, the warpTitle is used.)| +| bpm | To override the text "BPM" for beats per minute. | + +## SynthSequence + +Creates an object that builds data for `CreateSynth`. This is normally done internally if `CreateSynth` is passed a visual object, but this is a way to custom build any sequence. + +```javascript +var sequencer = ABCJS.synth.SynthSequence() +sequencer.addTrack(); +sequencer.setInstrument(0, 25); +sequencer.appendNote({ trackNumber: 0, pitch: 60, durationInMeasures: 1, volume: 80 }) + +var buffer = new ABCJS.synth.CreateSynth(); +return buffer.init({ + sequence: sequence, +}).then(function () { + return buffer.prime(); +}).then(function () { + return buffer.start(); +}); +``` +This is a helper object that will create an object that is consumed by `CreateSynth`. There is nothing special about this that you couldn't create the object by hand, but this provides some convenience functions. + +| Method | Parameters |Description | +| ------------- | ----------- | ----------- | +| `addTrack` | (none) | Returns the number of the track that was created. This must be called before anything can be added to the track. | +| `setInstrument` | `trackNumber, instrumentNumber` | `trackNumber` is the value that is returned by `addTrack`. instrumentNumber is the stand MIDI number for the instrument. (See `ABCJS.synth.instrumentIndexToName` for the list of instruments.) This should be called right after `addTrack` and may be called at any time after that to change the instrument midstream. | +| `appendNote` | `trackNumber, pitch, durationInMeasures, volume` | This adds a note. `trackNumber` is the value returned from `addTrack`. `pitch` is the standard midi pitch number. `durationInMeasures` is a floating point number where "1" is one measure. `volume` is a value from 0 to 255 that is the volume of the note. | + +## CursorControl object + +If you want notification when events happen, then you can pass in an object that you create yourself. Note that even though this object is called `CursorControl` it can be used for anything that requires knowledge of various events that happen during playback: when a note is played, when a beat is reached, when the end of a music line is near, when a measure starts, and when the music stops. + +The following properties are used: + +- beatSubdivisions + +How often to call the beat callback. If this is not set, then the beat callback is called once per beat. If you want a finer grained control, you can set this to a larger number. Notice that a large number will affect performance. + +- extraMeasuresAtBeginning + +How many extra measures to have at the beginning before the tune actually starts. This can be used for count in beats. + +- lineEndAnticipation + +When to call the onLineEnd event. If you want to scroll the music when the end of the line is reached, then you probably want to scroll it a little in advance so the user can read ahead. This is the number of milliseconds, so the value of 500 means to scroll the music one half second before the end of the line. + +- onReady(synthController) + +Called when the tune has actually been loaded. Because the audio buffer can only be initialized after a user gesture, the tune might not have been loaded when the visual control is created. This might be called when `setTune` is called, or when the user clicks PLAY. + +The parameter is the instance of the synthController that called it. + +- onStart() + +Called when the tune has actually started: that is, after all the set up has been completed. + +- onFinished() + +Called when the tune has finished. + +- onBeat(beatNumber, totalBeats, totalTime) + +Called each beat, or each subdivision of a beat. + + - beatNumber + +This is the current beat - in a perfect case, this is called regularly. There are various things that can cause JavaScript to stop running, though, so it might get called a bunch of times in a row to catch up. This can be a fraction, if `beatSubdivisions` is present. + +- onEvent(event) + +This is called every time a note, rest, or bar is encountered. + +The `event` parameter has these properties: + +| Property | Description | +|---|---| +| measureStart | `true` if this is the beginning of a measure. (Note, beware of the case where the only event at the beginning of a measure is a note tied from a previous note. There might not be anything to do.) | +| elements | The actual SVG elements that represent the note(s) being played. | +| left | The leftmost point of the current elements. | +| top | The topmost point of the current elements. | +| height | The height of the current elements. | +| width | the width of the current elements. | + +- onLineEnd(data) + +This is called when the end of the line is approaching. The data is the following properties: + +| Property | Description | +|---|---| +| milliseconds | The current time. | +| top | The top of the current line. | +| bottom | The bottom of the current line. | + +Use this to determine if the SVG should be scrolled. + +Example: +```javascript +var CursorControl = function() { + this.beatSubdivisions = 2; + this.onStart = function() { + console.log("The tune has started playing."); + } + this.onFinished = function() { + console.log("The tune has stopped playing."); + } + this.onBeat = function(beatNumber) { + console.log("Beat " + beatNumber + " is happening."); + } + this.onEvent = function(event) { + console.log("An event is happening", event); + } +} +var cursorControl = new CursorControl(); +synthControl = new ABCJS.synth.SynthController(); +synthControl.load("#audio", cursorControl, {displayPlay: true, displayProgress: true}); +``` + +## playEvent(pitches, gracenotes, millisecondsPerMeasure) + +This will play a single event that is passed. The event must have the same format as the events that are passed back by the click listener. + +### pitches + +An array of pitches. If there is more than one item in the array, they are played at the same time. Pitches contain: + +| Attribute | Description | +|---|---| +| pitch | An integer value of the pitch, where middle C is 60 | +| durationInMeasures | The length of the note. For instance, a quarter note in 4/4 would be .25 | +| volume | A number from 0 to 127 for the volume of the note. | +| instrument | The number of the instrument in the MIDI spec. | + +### gracenotes + +These are the same format as above, except that these notes are played before the main note for a short time. Also, if there is more than one note in the array, the notes are played sequentially. + +### millisecondsPerMeasure + +This is used to translate the `durationInMeasures` value into an actual time. + +### Example: + +```javascript +ABCJS.synth.playEvent( + [ // a C chord + {"cmd":"note","pitch":60,"volume":105,"start":0,"duration":0.125,"instrument":0,"gap":0}, + {"cmd":"note","pitch":64,"volume":105,"start":0,"duration":0.125,"instrument":0,"gap":0}, + {"cmd":"note","pitch":67,"volume":105,"start":0,"duration":0.125,"instrument":0,"gap":0}, + ], + [ // start with a D as a grace note + {"pitch":62,"durationInMeasures":0.125,"volume":70,"instrument":0} + ], + 1000 // a measure takes one second. +).then(function (response) { + console.log("note played"); +}).catch(function (error) { + console.log("error playing note", error); +}); + +``` + +## activeAudioContext() + +If there is an AudioContext that is being used then this retrieves it. It allows freely sharing the same one in different parts of your app. + +```javascript +var ac = ABCJS.synth.activeAudioContext(); +``` + +## instrumentIndexToName[index] + +This is an array that converts the standard MIDI instrument indexes to a name. For instance: +```javascript +console.log(ABCJS.synth.instrumentIndexToName[9]); +// "glockenspiel" +``` + +## pitchToNoteName[pitchNumber] + +This is an array that converts the standard MIDI pitch indexes to a name.

This has made the minimized package 90K smaller, and has increased the speed of generating the SVG image by about 6 times! + +For the most common use of creating either the sheet music or the audio, there isn't any change. + +However, if you use the animation callback in the audio to manipulate the notes, then be aware that, instead of receiving elements that are wrapped in a Raphael object, you now receive the actual +SVG element. For the most common example of the animation functionality, the following was recommended to change the color of notes: +``` +element.attr({ fill: color }); +``` +That should be changed to: +``` +element.setAttribute("fill", color); +``` + +* If you do specific manipulation of the SVG, you will need to retest your code. The generated SVG, while it looks the same on the page, has changed somewhat. The selectors you use may return different results. + +## Special notes for Version 4.0.0: +* **BREAKING CHANGE**: The names of all the classes that are generated are now prefixed with `abcjs-`. Any code that searched for particular class names before will have to be adjusted. + +* The parameters have been combined into one set of parameters, instead of three sets like previous versions. The old way of calling the parameters will still work, but you are encouraged to use the new, simplified approach going forward. + +## Special notes for Version 3.3.0: + +* The build process has switched over to webpack. The minimization is now done with UglifyJS. This shouldn't cause any side effects. + +* The "editor" version of the library has been rolled into the "basic" version. There is only the "basic" and "midi" versions now, since the editor code doesn't add much to the size. + +* The npm version has a new export called "signature" that gives your javascript code some version information. + +* The documentation has all been moved to the `/docs` folder. + +* The examples have all been moved to the `/examples` folder. + +## Special note for Version 3.2.0: + +abcjs is proud to announce that it can now be installed with `npm`. Instead of including the minimized files on your page, you can use the library by doing the following in your project: +```bash +npm install --save abcjs +``` + +Note that the minimized versions will still be maintained, so you can still copy the minimized file to your project. + +## Special notes for Version 3.0: + +In-browser [MIDI](/docs/upgrading/midi.md) is now supported. There are some extra dependencies when using that feature. Downloadable MIDI is still supported with no extra dependencies. + +## API Changes for Version 3.0 + +* Added viewPortHorizontal and scrollHorizontal to the renderParams. +* Add class "slur" to slurs and ties. +* Add "hint measure" +* Allow scrolling in the animation. +* Handle %%titlecaps directive. +* Add curly brace to indicate piano part (with inspiration from Anthony P. Pancerella). +* Add invisible marker to the top of each system so that it can be found easily. +* Add an option to put each line in a separate svg so that browsers will paginate correctly. + +## API Changes for Version 3.0 Beta + +* The default MIDI program has been changed to "0". + +* There are a number of new MIDI parameters. + +## API Changes for Version 1.11 + +"Bouncing Ball" cursor: + + ABCJS.startAnimation(paper, tune, options) + paper: the output div that the music is in. + tune: the tune object returned by renderAbc. + options: a hash containing the following: + hideFinishedMeasures: true or false [ false is the default ] + showCursor: true or false [ false is the default ] + bpm: number of beats per minute [ the default is whatever is in the Q: field ] + +`renderABC()` now returns the object that was created by the process.

Add note names

+  

+  

+	  
This will add note names underneath all the pitches. The trick is to create a dummy lyric line with "w: Z Z Z ..." then after the tune is rendered to replace the text with the note name. You can make the "w:" longer than the number of notes - any lyrics that are extra are just ignored. You can use two characters for each of the lyrics if you want to allow more space.

+    

+      This is a simple example of how elements can be found on the page and how
+      annotations can be drawn.
+    

+    
1) Note that annotations above the staves are written into the ABC notation using the syntax "^text".

+    
2) Note that room is created for annotations below the staves by creating a w: line and then setting its fill to none on the stylesheet.

+    
3) Note that the notes are retrieved by their unique class and their position is retrieved. When the music is changed,
+    this will automatically move the drawn lines to the right place.

+    

+
+    
+    
+    
Note that \ is a character which must be escaped in JavaScript.

abcjs swing with editor

+

+    

+      
This demonstrates the addition of swing in a tune.
+        The swing is added to the MIDI player, so it is not reflected in the sheet music.
+        The swing is represented as a percentage of the duration of the first note to the
+        duration of the pair of eighth notes.
+        The default is 50%, which is no swing; both eights have the same duration and the ratio is 1:1.
+        66% is a common value for triplet-swing, with a 2:1 ratio of the first note to the second.
+        Other common swing values are 60% which corresponds to a 3:2 ratio of the first note to the second and 57%
+        which corresponds to a 4:3 ratio.
+        The maximum value of swing is 75; in this case the first half of the pair is 3 times longer than the second
+        half.
+        resulting to a 3:1 ratio or a dotted-eighth followed by a sixteenth note.
+      

+      
In the example below, change the value of the swing to see how it matches of differs from the explicit
+        triplets of dotted eighth and sixteenth notes.
+      

+      

+        Swing is supported in all X/4 and X/8 meters. In a X/8 meter the sixteenths swing.
+        You can try a X/8 meter by changing the meter in the ABC string to "M: 4/8
+        L: 1/16"
+        However, meter changes in the middle of a tune do not affect the main swing duration.

abcjs transposition with editor

+  

+  

+    

+      
This demonstrates the different methods of transposition. It is possible to transpose by inserting commands
+        into the ABC string or by using parameters when calling the rendering function. When using the parameters the transposition always adds to whatever the ABC string says. When inserting strings into ABC that always uses the last transposition encountered.

+      

+

+          
Transpose Parameters

+          
These are added to whatever is in the tune (in half steps)

+          
+          
+          
ABC Insertions

+          
These all do the same thing.

This is a complete demo of what you can do with matching audio with the visual music.

+      
Different pieces of music are provided to demonstrate changing tunes. To toggle between the pieces, click "Next Tune".

+      
You are in control of the look of the cursor. Two different techniques are demonstrated: highlighting the note being played and putting a cursor on the page. The class CursorControl must be supplied by your program.

+      
As the piece is playing, there are callbacks when the note changes. The info returned in the callback is printed to the page as it is received.

+      
The visual control for playing music can look different. In this example, the abcjs-audio.css file has been loaded. You can supply your own css.

+      
+      
+      
+

+			First start playing to load audio before seeking.

PDF Maker

+  

+  

+    

+      

+        

+          This page demonstrates how to take the output of abcjs and make a nicely formatted PDF out of it. It does that by using the browser's built in print capability. The
+          browser's "Print Preview" dialog contains an option to "print to PDF".
+          (It is useful to use the "oneSvgPerLine" option when printing. This will keep the browser from breaking the music in the middle of a staff when there is a page break.)
+        

+        
    
+          
  • 
+            Use the input dialog below to create the music you wish to print.
    • 
+          
  • 
+            Use the music player to test your input for typos.
    • 
+          
  • 
+            Click the "print" button to save as PDF.

Reusing Synth

This shows how you can create and save snippets of music so that it is easy to replay them.

+		
When you click "Prime" all of the buffers are created from the same music - playing different sets of voices
+			at different tempos.

+		
Then the user can play them repeatedly with very little additional processing.

Tempo

+  

+	

+		
Tempo can be set in various ways: it can be specified in the ABC string, it can be specified in the
+			parameters passed in, or a default can be set that is only used if the tempo is not in the string.
+		

+		
+		
Specified in the ABC String

+		
The tempo is set using the Q: 1/4=150 line.

+		

+		

+			

+				
+				
+			

+		

+
+		
Passed in as a Parameter

+		
The tempo is set using the { qpm: 100 } attribute. Notice that this overrides the tempo in the Q: line.

+		

+		

+			

+				
+				
+			

+		

+
+		
Using a default

+		
The tempo is set using the { defaultQpm: 60 } attribute. Notice there is no Q: line.

+		

+		

+			

+				
+				
+			

+		

+
+		
The tempo is set using the { defaultQpm: 60 } attribute. However, there is a Q: line, so that takes precedence.

+PREAMBLE
+The goals of the Open Font License \(OFL\) are to stimulate worldwide development of collaborative font projects, to support the font creation efforts of academic and linguistic communities, and to provide a free and open framework in which fonts may be shared and improved in partnership with others.
+
+The OFL allows the licensed fonts to be used, studied, modified and redistributed freely as long as they are not sold by themselves. The fonts, including any derivative works, can be bundled, embedded, redistributed and/or sold with any software provided that any reserved names are not used by derivative works. The fonts and derivatives, however, cannot be released under any other type of license. The requirement for fonts to remain under this license does not apply to any document created using the fonts or their derivatives.
+

Editor Instructions

+
Use this to play with different character shapes in Raphael. After creating the shape you want, paste the output code into
+	abc_glyphs.js. The legal things to put in the textarea are "M", "l", or "m" followed by two numbers. The last character must be a "z".
+

+

+	The "l" element MUST be lower case (that is, use relative coordinates). The path is calculated from the beginning of the entire SVG, so
+	absolute coordinates will end up in the upper left of the engraving.
+

+

+	For instance, the following is the shape of a whole rest:
+

+
M0.06 0.03
+l0.09 -0.06
+l5.46 0.00
+l5.49 0.00
+l0.09 0.06

+l-0.06 0.09

These are all the characters available to abcjs. Not all of them are used, however. The actual
+	characters that are in abcjs are listed in scale_font.js in the object glyphnames.
+	Click "Generate Font Code" to generate the code that should be put into abc_glyphs.js to make the characters available.

+ * array types cannot contain non-numeric properties
+ * change enum type to Enum to avoid reserved word.

+# Architecture of the engraver
+
+The engraver code is handled here. This accepts the output of the parser and does three things:
+
+* Creates an SVG
+* Adds data to the parser input
+* Makes the visual elements interactive
+
+## Steps
+
+There are separate passes and sub-passes to the processing. The separate passes match the subfolder organization here.
+
+They are:
+
+### Element Creation
+
+The structure passed in from the parser is traversed and all elements are created. An element consists of two parts:
+
+* The Absolute Element: a visual piece of music that is always moved together. For instance, in the key signature of D, the absolute element is an object that contains two sharp symbols. The absolute element has an X- and Y- position in the SVG, and an array of Relative Elements.
+
+* Relative Element: These are always attached to an absolute element. They have a relative position to the absolute element and consist of all the glyphs needed. For instance, a dotted eighth note of Bb that is trilled is an absolute element that contains an array of relative elements consisting of a trill, a flat sign, a filled note head, a stem, a flag, and a dot.
+
+Each of these elements is a separate object, created with `new` and placed in the structure passed in from the parser.
+
+### Layout
+
+After all the elements are created the size of all of them are known, so the layout process begins. There are separate layout algorithms for the horizontal and the vertical positioning. 
+
+### Drawing
+
+After the layout is finished, it is a rote process to draw the music. All decisions have been made. The structure is then traversed and each element is created in the SVG.

+
+var highlight = require("../../interactive/highlight");
+var unhighlight = require("../../interactive/unhighlight");
+
+// Everything that is placed in the SVG is first created as an absolute element. This is one unit of graphic information.
+// That is, it embodies a concept: a clef, a time signature, a bar line,etc. or most complexly:
+// a note with its accidental, grace note, chord symbol, trill, stem, eighth flags, etc.
+// In the largest sense, these are placed on the page at a particular place that is determined during the layout phase.
+// This object doesn't contain any of the drawing information, though. That information is contained in an array of
+// RelativeElements as the "children" of this class.
+// During the layout phase, the width of all the children is calculated and the X coordinate of the absolute element is set.
+//
+// So, after the AbsoluteElement is placed, then its children can be placed relative to that. There are different types of
+// relative elements that are placed with different rules:
+// 1) Fixed - these elements don't move relative to the absolute element's coordinates. These are things like the notehead,
+// any ledger lines, accidentals, etc.
+// 2) Slotted - these elements can move vertically and don't get Y coordinates until after the absolute element is placed.
+// These are things like the chord symbol, many decorations, the lyrics, etc.
+//
+// Relative elements are also classified by how they are related. This could be:
+// 1) Increases the absolute element's width to the left. This doesn't change the center point of
+// the absolute element, so adding a sharp to the note won't move it to the right. However, if the elements
+// are close together then this enforces a minimum distance.
+// 2) Has no effect on the width. Annotations and the tempo act like this. No matter how long they are the width doesn't change.
+// 3) Increases the absolute element's width to the right. This doesn't change the center point,
+// but it will increase the minimum distance.
+// 4) Sets the width on both sides. This is the note heads. They are centered on both sides of the absolute element's X coordinate.
+
+// duration - actual musical duration - different from notehead duration in triplets. refer to abcelem to get the notehead duration
+// minspacing - spacing which must be taken on top of the width defined by the duration
+// type is a meta-type for the element. It is not necessary for drawing, but it is useful to make semantic sense of the element. For instance, it can be used in the element's class name.

+// Most elements on the page are related to a particular absolute element -- notes, rests, bars, etc. Beams, however, span multiple elements.
+// This means that beams can't be laid out until the absolute elements are placed. There is the further complication that the stems for beamed
+// notes can't be laid out until the beams are because we don't know how long they will be until we know the slope of the beam and the horizontal
+// spacing of the absolute elements.
+//
+// So, when a beam is detected, a BeamElem is created, then all notes belonging to that beam are added to it. These notes are not given stems at that time.
+// Then, after the horizontal layout is complete, all of the BeamElem are iterated to set the beam position, then all of the notes that are beamed are given
+// stems. After that, we are ready for the drawing step.
+
+// There are three phases: the setup phase, when new elements are being discovered, the layout phase, when everything is calculated, and the drawing phase,
+// when the object is not changed, but is used to put the elements on the page.

+//
+// Methods:
+// constructor: some basic initialization
+// addVoice(): Called once for each voice. May add a new staff if needed.
+// finished(): Called only internally by layout()
+// layout(): This does all the layout. It sets the following: spacingunits, startx, minspace, w, and the x-coordinate of each element in each voice.
+// draw(): Calls the underlying methods on the voice objects to do the drawing. Sets y and height.
+//
+// Members:
+// staffs: an array of all the staves in this group. Each staff contains the following elements:
+//    { top, bottom, highest, lowest, y }
+// voices: array of VoiceElement objects. This is mostly passed in, but the VoiceElement objects are modified here.
+//
+// spacingunits: number of relative x-units in the line. Used by the calling function to pass back in as the "spacing" input parameter.
+// TODO-PER: This should actually be passed back as a return value.
+// minspace: smallest space between two notes. Used by the calling function to pass back in as the "spacing" input parameter.
+// TODO-PER: This should actually be passed back as a return value.
+// startx: The left edge, taking the margin and the optional voice name. Used by the draw() method.
+// w: The width of the line. Used by calling function to pass back in as the "spacing" input parameter, and the draw() method.
+// TODO-PER: This should actually be passed back as a return value.  (TODO-PER: in pixels or spacing units?)
+// y: The top of the staff group, in pixels. This is set in the draw method.
+// TODO-PER: Where is that used? It looks like it might not be needed.

+# Automated Tests
+
+## Mocha
+
+Currently there are two sets of mocha tests.
+
+Either:
+
+Run with:
+```shell script
+npm run test
+```
+
+this will pass all `.js` files to mocha.
+
+or
+
+To run browser based tests, load the `.html` file into the browser. That will run
+all of the tests associated with that file. To run just some of the tests, use the query parameter:
+This will most like need a server to serve the `.html` files to solve CORS issues.
+```
+?grep=test-name
+```
+where `test-name` is any part of the test name. All the tests that match will be run.
