Methods
- Kotlin
- Jetpack Compose
- Android audio
- USB MIDI
- Chord-aware sequencing
Outputs
- Installable Android APK
- Internal audio
- Finite stereo WAV export
- Optional USB MIDI output
Result
A working mobile instrument that can play independently, export its internal mix, or route its four lanes to MIDI hardware.
Implementation
How it works
The Kotlin and Jetpack Compose application generates chord-aware material across four lanes and plays it through internal Android audio or optional USB MIDI.
The selected experimental sound build is v0.1.28, build 29, with stable beta v0.1.27 retained as a separate fallback.
