Android app / v0.1.13 debug build

Operon Splicer

Playable Android generative melodic synth with four lanes, MIDI out, a parchment instrument interface, compact performance controls, direct-adjust musical status plates, pattern editing, FX, modulation, routing, presets, and transform-first Recombine flow.

Download the debug APK, sideload it on Android, press Play, and use Randomize, Recombine, or Mutate to shape Bass, Hook, Harmony, and Texture variants with internal audio or connected MIDI hardware. Use Split 1-4 for multitimbral devices, Merge Ch.1 for one-instrument setups, or EP-133 Pad mode for pad groups A-D.

0.1.13 restores the compact aligned performance UI and removes the experimental full-screen art layer while the next asset pass is rebuilt correctly.

0.1.11 added Karplus plucks, resonant bells, phase-fold leads, formant pads, and new FX color modes.

FX memory modes now shape the live DSP path for crusher, clock dissolve, tape, slicer, comb, and spectral smear behaviors.

Native Compose controls for Perform, Pattern, Chord, Sound, FX, Mod, Routing, and Presets over a parchment instrument surface.

Separate Randomize, Recombine, and Mutate actions: broad reroll, lane-material cycle, or FX-only mutation.

BPM, Key, Scale, and Chord plates show values with direct -/+ hit zones for quick testing.

Master Volume controls internal phone audio without changing MIDI velocity.

Options persist Master Volume, MIDI clock default, Auto EP-133 mode, Keep Screen Awake, and preset favorites.

MIDI feedback shows selected device, profile, active mode, clock out state, last event, and sent count.

MIDI out supports split lanes, Merge Ch.1, or EP-133 pad groups with clock out.

The top bar now has a device UI profile layer, so EP-133/K.O. II setups can get hardware-specific presentation without changing synth logic.

Pattern slots now store and recall real per-lane patterns instead of acting like decorative buttons.

EP-133 demo setup

Connect Android USB-C to the EP-133 USB-C MIDI port, then open Routing and select the EP-133 output.

Operon Splicer should show EP-133 mode, Clock Out: On, and Pads A-D on Ch. 1.

Use Test Note first, then press Play. The EP-133 produces the sound; Operon sends generated notes and clock.

This is fan/demo-safe EP-133 support. It does not imply Teenage Engineering endorsement, partnership, or certification.

Install notes

Package / `com.recombinase.operonsplicer`

Build / v0.1.13 debug-signed APK for direct testing.

Master Volume affects phone audio only; MIDI velocity stays generated by the lanes.

EP-133 mode maps lanes to pad groups A-D on Ch. 1 and enables clock out.

Options and favorite presets persist between launches.

Pattern slots are real lane pattern memory in this build.

USB MIDI is optional; no MIDI device should not crash the app.

Stop clears internal voices and sends safe all-notes-off messages when MIDI is connected.

Use wired audio for testing. Bluetooth latency can make live play feel late.
