SYNTHIA

Features

• Game Mode: Start an interactive call-and-response session where the AI listens to your playing and responds musically
• Instrument: Choose the synth sound and effects for your keyboard—Synth, Piano, Organ, Bass, Pluck, or FM Synth create different tonal qualities
• AI Voice: Select which instrument sound the AI uses when it responds to your playing
• Engine: Choose how the AI responds:
  • Parrot: Repeats exactly what you played
  • Reverse Parrot: Plays your notes in reverse order (backward)
  • Godzilla: Uses AI to generate a musically coherent continuation of your phrase
• Runtime: Select where the AI runs—CPU (slower, always available), ZeroGPU (faster if available), or Auto (prefers GPU, falls back to CPU)
• AI Style: Post-processing that shapes the AI's melodic style (Godzilla engine only):
  • Melodic: Smooth, singable melodies with minimal pitch leaps
  • Motif Echo: Echoes the first couple notes from your input at the end of the response
  • Playful: Adds bouncy alternating pitch shifts for a whimsical character
• Response Mode: Determines the processing pipeline and sampling creativity (Godzilla engine only):
  • Raw Godzilla: Pure AI output with maximum creativity (temperature=1.0, more unpredictable)
  • Current Pipeline: Balanced mode applying your AI Style with moderate creativity (temperature=0.9, best of 3 candidates)
  • Musical Polish: Refined mode with advanced processing—quantizes pitches to musical scales, adjusts rhythm, blends velocities, and ensures musical coherence (temperature=0.85, picks best of 4)
• Response Length: How many notes the AI generates—Short (8 notes), Medium (14 notes), Long (20 notes), or Extended (28 notes)
• Record/Playback: Record your keyboard performance and play it back to hear it again
• Save MIDI: Export your recordings as MIDI files for use in DAWs or other music software
