Ver 1.0.3 2026-10-06
In this update: keep editing while your song plays, smoother AUv3 plugins, swipe to turn a note off, and a batch of fixes.
NEW
- Swipe a step to the right to turn its note off. Swipe it again to bring the note back.
- Keep editing while your song plays: add, duplicate, move or delete tracks, change instrument types and load presets without audio dropouts. New tracks fade in and deleted ones fade out.
IMPROVED
- AUv3 plugins load without interrupting playback. The rest of the song keeps going and the plugin fades in once it has loaded. When you switch an instrument to a plugin, the old sound keeps playing until the plugin is ready.
FIXED
- Undo and other changes made while a song plays no longer pop. AUv3 plugins keep playing through them, keep the settings you changed in the plugin's own screen, and never go silent afterwards.
- One plugin instrument used on several tracks now behaves as one instrument.
- Undoing a change made in the FX editor no longer pauses or restarts playback.
- Removing a phrase from the grid while the song plays now stops its note instead of leaving it ringing until you press Stop.
- Plugin instruments that stopped working after your phone was locked (silent, and their window would not open) now reload automatically with their settings when you return to the app.
- Turning an AUv3 instrument’s Built-in Filter on or off no longer causes a pop or a gap in the sound, and no longer resets the plugin’s settings.
- Exported audio now includes the Built-in Filter on AUv3 instruments.
- Editing the modulation on one AUv3 instrument no longer changes the modulation of other AUv3 instruments.
- Fixed a freeze that could close the app after collapsing and then expanding a section on the Song page.
- Fixed a rare case where, after the app closed unexpectedly, Save could write your song over a different song file. If the app can’t be sure which file your song belongs to, only Save As is offered.

Ver 1.0.2 2026-08-11
In this update: free-form select, FX editing across a whole selection at once, small ui improvements, and a batch of fixes.
NEW
- Free Select: selections no longer have to be rectangles. Tap "Free" in the selection menu, then tap any cells to add or remove them one by one, or hold a cell for a moment and drag to sweep up several at once.
- Edit FX values across a whole selection at once.
IMPROVED
- The FX list now keeps last scroll position instead of jumping to the top every time.
- UI enhancement: knobs, buttons and panels updated.
FIXED
- The ARP command now works the way arpeggios do in classic trackers: it bends the pitch of the playing note instead of restarting it — so pads and long samples arpeggiate smoothly instead of stuttering — and notes held past an ARP row now return to their original pitch instead of staying stuck on the last arpeggio step.
- The Subtle visual feedback setting now actually shows the same on-beat flashes as full, just dimmer, instead of doing nothing.
- Level meters now respond almost instantly instead of trailing the sound.
- Removing the last target from a sidechain routing no longer crashes the app.
