The problem
A mobile instrument needs to generate and reshape musical parts, play them without external hardware, and export audio for use elsewhere.
Creative technology / 2026
Operon Splicer
Android instrument with four chord-aware lanes, internal synthesis, optional MIDI, and WAV stem export.
My role
Instrument design, Android interface, pattern generation, and audio/MIDI engineering.
What I built
- Installable Android instrument
- Four-lane internal synthesis and optional USB MIDI
- Saved variants and finite WAV exports
The result
A mobile instrument that plays independently, exports its internal audio, and can route lanes to external MIDI hardware.

Implementation
How it works
The Kotlin and Jetpack Compose app generates chord-aware material across four lanes. It plays through internal Android audio or optional USB MIDI, saves variants, and exports finite WAV audio. Muting the other lanes isolates a part for export.
Technical context and methods
The selected public beta is v0.1.29, build 30, with a versioned APK and matching checksum.
