midi, synthesized audio, ABC code triples

(this dataset contains those with audio duration in 5 min - 2 hours, less than 5 min data are in [300s](https://huggingface.co/datasets/Yi3852/midi-audio-abc_300s)
and there are several subsets with smaller duration 
[60s](https://huggingface.co/datasets/Yi3852/midi-audio-abc_60s)
[30s](https://huggingface.co/datasets/Yi3852/midi-audio-abc_30s)
[10s](https://huggingface.co/datasets/Yi3852/midi-audio-abc_10s))

(`token_length_abc` field represents the token count of the abc text w.r.t. Qwen3's tokenizer)

+ midi files are from [bread-midi-dataset](https://huggingface.co/datasets/breadlicker45/bread-midi-dataset)
+ synthesized audio: use Don Allen's [Timbres of Heaven](https://www.midkar.com/SoundFonts/index.html) as soundfont and [FluidSynth](https://www.fluidsynth.org/) as synthesizer
+ [abc notation](https://abcnotation.com/): mid2abc by [EasyABC](https://github.com/jwdj/EasyABC) (midi2abc.py)
