The first update since launch — new sidechain controls, a big batch of table improvements, and several fixes. There is also a new in-depth walkthrough video, linked at the end of the tutorial and in Settings. NEW - Sidechain Trigger mode added: each hit of the source fires one clean duck that recovers at the speed you set with the release knob - Sidechain threshold knob: control how loud the source needs to be before the target ducks. - Table HOP can now repeat a set number of times instead of only looping forever. - Table speed UI improved and range increased. - After an update, a short "What's New" summary appears one time. Bring it back any time from Settings, under About. - "Show Touches" option in Settings. Useful for screen recording walkthrough videos such as the new one that coincidentally uses that feature. IMPROVED - UI for BPM and Swing can now be opened by tapping either value. More intuitive, easier to use than the original scrub-only implementation. - Rename instruments and tables by tapping their name — no need to save a preset just to name an instrument. - New Song now starts you on a blank canvas. - The app now says "phrase" everywhere for consistency. Some screens used to say "pattern." FIXED - Tables now stay locked to the beat. A table set to advance one row per step used to drift slowly out of time and snap back each time the phrase looped. - Table speeds above 6 now work. - More table fixes: a chance roll on the last row no longer ends the table early, a row holding only a HOP no longer blips the pitch on the way past, two HOPs on the same row now take turns properly, previews follow a HOP on the first row, and steps that nudge their timing no longer pull a table out of time. - The delay's ping-pong mode now bounces between both ears at equal strength, and its MOD wobble sweeps the left and right channels separately for a wider stereo shimmer. - It is now much more difficult to accidentally nudge a track's fader in the mixer. - After pausing and resuming playback, the first notes no longer play too loud or at the wrong brightness. - Switching songs no longer carries the last song's phrase number and copied cells over. - Cloning a phrase on the song page now gives it the next free number instead of one in the 240s, which was possible after certain interactions. - A phrase's preview in its song page cell updates as soon as you leave the phrase editor. - Opening a song no longer warns about instrument slots you simply haven't filled in yet.
