Firmware v0.3 is a big musical and structural release: Shepard Tone, Note Track, Boomerang envelopes, tempo nudge from continuous controls, better sensors, and a storage split so your scenes and custom pedals survive firmware updates.
Highlights
- Shepard Tone generator — New RTG mode with rising or falling infinite glissandi, single- or multi-channel voice layouts, fade via CC11 or poly aftertouch, and stream / wide / crossfade smoothness styles.
- Note Track — Map incoming MIDI notes to control changes and other parameters, with configurable note range, channel, and filter modes — turn a keyboard into a performance controller for the scene.
- Boomerang actions — ADSR-style envelopes that can drive CCs, LFO targets, and related outputs, with configurable attack / sustain / release timing for expressive one-shot morphs.
- Tempo nudge from continuous inputs — Expression, CV, proximity, ALS, and touchwheel can gently push tempo up or down by a percentage while you play — no separate tap needed for small feel adjustments.
- Your content survives updates — Scenes, custom pedals, and personal assets move to a dedicated userdata area; shared factory content stays separate. Firmware updates are less likely to wipe your library.
- Stuck-note prevention — Local MIDI output tracking releases held notes on scene changes and programming-mode transitions, so on-device producers are less likely to leave hanging notes.
- Tilt sensing — Accelerometer integration adds tilt alongside bump, so motion can drive scene behavior in more ways.
Bonus round
- Action feedback on screen — Executed actions can show summaries in the Khyron UI module so you see what just fired.
- Better MIDI clock timing — Microsecond-based tempo scheduling and cleaner unmute reset (avoids catch-up bursts when clock comes back).
- Proximity improvements — Sunlight cancellation (reject ambient IR) and gamma correction for more usable inverse-square response.
- Clock burst & punch-in actions — Additional MIDI/performance action tools in the expanded action set.
- Menu navigation polish — Stack rebuilding and Global Config navigation make deep menus less confusing.
- Expanded pedal library — midi-devices catalog updates bundled with the release.
