Android / visual splicer beta v0.3.0-beta.25 debug build

ExoAVT

A native Android visual splicer for turning imported video or photos and embedded or attached audio into deterministic, audio-reactive effects and exported MP4 variations.

Beta 0.3.0-beta.25 keeps the complete seven-control and live-preview repair while giving the centered, single-line RANDOMIZE and EXPORT labels more breathing room inside their existing illuminated controls.

Private testing cohort

Recombinase access required

Want to test the operon splicer? Follow for development updates and comment BETA on the newest ExoAVT post to request access. I am personally selecting the first testing cohort. Access is limited and not guaranteed.

Then DM BETA, your phone model, Android version, and what kind of visuals or audio you make.

Codes are issued directly through the official profiles above. Never pay anyone for ExoAVT beta access.

  • Import an existing video or photo through Android's system photo picker, use the MEDIA control beside Settings to replace it, or Share/Open supported media with ExoAVT.
  • Attach WAV, FLAC, MP3, AAC, or other provider-supported audio through the system document picker.
  • Work through one responsive native machine whose decorative chassis extends beneath Android's system areas while every usable control stays inside the phone's safe insets.
  • Use seven persistent Glitch, Smear, ASCII, Filter, Wobble, Fry, and Dither control positions whose displayed effect assignments and values always reflect the current Randomize, Mutate, or manual result.
  • Analyze embedded or attached audio locally into a timestamped RMS/peak timeline, with the machine's signal light driven by the same analysis used by the effects.
  • Compare Source and Processed playback across 15 stateless effects: Posterize, RGB Split, Scanlines, Pixelate, ASCII, Exposure, Contrast, Black Crush, Saturation, Threshold, Ordered Dither, Sharpen, Vignette, Mirror, and Wave.
  • Drag anywhere on a loaded effect module to make a bounded direct change—even while it reads OFF—or tap its dial, label, or value area to toggle bypass while preserving the last nonzero amount; feedback reaches the visible preview immediately, and only the indicator moves while the bezel, scale, shadow, and lighting stay fixed.
  • Choose from 16 named organisms, including Operon Reactive, ASCII Reactor, Red Hot Burning, Ghost Signal, Necrotic CRT, Memory Wound, Mirror Cell, and Wave Machine.
  • Use seeded Randomize to choose and reroll a different non-clean organism, then use Mutate to vary the current organism while preserving its topology and effect locks.
  • Turn Audio FX to ON to enable descriptor-owned RMS/Peak routes for every effect-bearing organism, or leave it OFF for a static recipe.
  • Process photos through the same effects, organisms, Randomize, Mutate, intensity, and audio-reactive routes as video; a photo without imported audio becomes a 10-second composition, while imported audio sets its composition duration and reactive timeline.
  • Inspect human-readable recipe values and set one shared global intensity from 0–200% in Settings; 100% preserves the authored look and higher values use bounded effect-specific overdrive.
  • Normalize supported HDR input to a protected SDR working surface on Android 10 or newer before effects and export.
  • Export the processed result as an H.264/AAC MP4 through Android's save picker, with progress, cancellation, encoder-safe photo sizing, and embedded, imported, mixed, or muted audio policies.
  • Save versioned projects and patches in app-private storage, then explicitly resume the last session or start fresh on launch.
  • Keep media centered and aspect-correct inside the native hardware preview bezel, with Compose Settings and default-off Technical Details secondary to the creative flow while preserving diagnostic access for beta testing.

Install

Android beta installation

  1. Open this page on an Android 8.0 or newer phone or tablet.
  2. Download the APK and allow installs from your browser or file manager if Android asks.
  3. Install ExoAVT, open Effects, then choose Import media or share/open a supported video or photo with the app.
  4. Use SRC and FX inside the compact monitor to compare the clean and processed loop.
  5. Press the illuminated Randomize control to choose a different organism or Mutate to vary the current one, then confirm the visible effect names, values, and dial pointers update to match the result.
  6. Turn Audio FX to ON, confirm the machine's signal light responds when analysis is ready, and adjust Global intensity to taste.
  7. For a photo, optionally attach separate mastered audio; after analysis it sets the composition duration and becomes the reactive and export source.
  8. Under Output, press the illuminated Export control, select a save location, and keep ExoAVT open until Android reports that the MP4 was saved.
  9. Use Settings only when you need project or technical controls; Live is an honest preview of the planned performance surface and does not record from the camera yet.

Android / experimental sound build v0.1.28

Operon Splicer

Generative melodic synth with four lanes, internal audio, MIDI out, pattern editing, effects, modulation, routing, and presets.

Sound build 0.1.28keeps the working UI and finite WAV export while expanding to 14,800 tested sound recipes across 27 playable engines and 96 FX palettes. Waveguide brass, bowed string, vector morph, and sympathetic comb resonance add four genuinely different sound families. Each lane has a mute toggle, so you can mute three lanes and export the remaining sound as an isolated WAV sample. The first-launch introduction now stays open until BEGIN SELECTION is pressed. Playback still stops when the app is hidden by default; opt-in Background Play now uses Android's media-playback foreground service for stable deliberate sessions. Build 0.1.27 remains available as the unchanged fallback.

Features

Performance and routing controls

  • Four chord-aware lanes: Bass, Hook, Harmony, and Texture.
  • Internal phone audio works without external MIDI hardware.
  • Chord- and scale-aware organic, Euclidean, arpeggio, syncopated, and 16-step-aligned clave pattern generation.
  • Recombine, Randomize, Mutate, Engines, Drift, and Undo transform actions.
  • Locks preserve selected parts while other material changes.
  • Stabilize stores the current state as a saved variant.
  • 14,800 role-specific sound recipes built from 148 authored foundations and 100 deterministic profiles.
  • 27 playable engines, adding waveguide brass, bowed string, vector morph, and sympathetic comb resonance to the existing oscillator, FM, supersaw, sample, granular, looper, pluck, bell, resonant-bass, VOSIM, modal, additive-organ, hard-sync, phase-fold, formant, drone, noise, and lo-fi families.
  • 96 named FX palettes with tempo-aware delay, ambience, granular, freeze, memory, chorus-orbit, all-pass phaser, modulation, and final limiting.
  • Per-lane mute, volume, stereo pan, and FX send are preserved in phone playback and WAV export.
  • Mute any three lane activity displays to export the remaining lane as an isolated WAV sample.
  • Exports the current internal mix as a 4, 8, 12, 16, 24, or 32-beat stereo WAV.
  • A compact versioned first-launch introduction remains visible until BEGIN SELECTION is pressed.
  • Playback stops when the app is backgrounded by default; opt-in Background Play uses Android's media-playback foreground service for deliberate sessions.
  • Optional USB MIDI output with EP-133 pad-group and clock support.
  • Preset save and load controls.
  • Panic stops internal voices and sends MIDI all-notes-off messages.

EP-133 setup

USB MIDI test path

  1. Connect Android USB-C to the EP-133 USB-C MIDI port, then open Routing and select the EP-133 output.
  2. Confirm EP-133 mode, Clock Out: On, and pads A-D on channel 1.
  3. Use Test Note first, then press Play. The EP-133 produces sound while Operon sends notes and clock.

EP-133 support is provided for testing and demonstration. It does not imply Teenage Engineering endorsement, partnership, or certification.
