Highlights: CUSTOM SCALES — create and store up to 16 custom scales with a built-in piano editor; saved as files on SD card. MIDI OUTPUT EFFECT — sends MIDI at any point in the effect chain for split MIDI+CV workflows. BERNOULLI EFFECT — probabilistic routing between two paths. TRACK NAMING — custom names up to 12 chars, persisted across saves. USB HOST COMPATIBILITY — major improvements; Sequential Take 5, OB-X8, OP-1, ROLI Seaboard M, Roland A-88 and more now work. JITTER MONITOR — measures NOTE ON timing jitter for MIDI DIN, USB DEVICE and USB HOST.
Effects: HOLD effect, EUCLID RESET param, MOD INTERPOLATION curves (OFF/LIN/S-curve/LOG/EXP), ENV release for aftertouch, GLIDE extended to 1 min, more clock divisions, SONG MODE improvements.
Bug fixes: crash fixes for STEP EDIT multi-selection, USB HOST/DEVICE MIDI clock jitter during SD card operations, CV INPUT voltages above 5V now correctly read, clock output state on MIDI stop fixed.

New Features NEW MUTE BEHAVIOUR : New setting "MUTE AFFECTS INPUT" modifies track muting behaviour. When set to "YES", muting a track silences all MIDI, including post-FX output—replicating the legacy behaviour. When set to "NO" (default), only sequenced events are muted; incoming MIDI continues to pass through the effects chain and is routed to the outputs. CV/Gate IN SETTINGS: New "GATE CAPTURE" parameter that introduces a configurable delay between gate onset and CV sampling, allowing time for voltage stabilization—particularly beneficial with high-slew-rate CV/Gate sources. ENV: New "RETRIG ATTACK" parameter that defines the envelope's response on retrigger, preventing abrupt resets to zero—particularly advantageous when driving VCAs, where smoother retrig transitions are typically preferred. ENV/LFO: Muting, deleting, and changing the destination now sends the 'default value' of the signal beforehand. JITTER MONITOR: A new mode that provides statistical analysis of incoming clock signals, including metrics such as BPM stability and timing jitter. Bug fixes Fixes crash on project load, with certain projects SETTINGS: "ACTIVE TRACK MOD" now uses a more sensible default value of "OFF" ONAIR: notes would sometimes get stuck when changing parameters ENV: improved signal aliasing ENV: Simultaneous NoteOff and NoteOn messages could cause a failure to retrigger ENV: "SIDECHAIN" parameter note values were displayed off by one STEP: Rotating a gate sequence was not possible on a MOD layout TRACK MODE: TRACK+PAD combo could change the track page
