S2400_20260522.upd

This update is mainly bug fixes and stability improvements.

A lot of these came from forum reports. Thank you to everyone who posted clear examples and followed up with extra detail.

Fixes

  • Fixed Loop/Slice looping turning itself back on after repeated pad hits. (forum t/11870, thanks @PitchItDown)
  • Fixed sample preview playing at the wrong pitch while browsing files. (forum t/11748, thanks @jeanvoyage)
  • Fixed zipper noise when moving the Live Loop volume fader. (forum t/5699, thanks @kulturhaus)
  • Fixed Live FX not triggering immediately after loading a saved project. Live FX fader, top-knob and bottom-knob positions now restore correctly too. (forum t/11554, thanks @dotist)
  • Fixed Copy+Pad from Bank D to other sample banks. Live Loop sources still stay within their own bank as intended. (forum t/11969, t/12125, thanks @PitchItDown and @DONDON)
  • Fixed Record Overwrite on gated or looped tracks wiping more of the pattern than intended. (forum t/12145, thanks @fatcompressor)
  • Fixed Step Program Copy+Pad on a gated note stretching an existing noteā€™s gate to the end of the pattern. Erase+Pad and F4+Pad are fixed too. (forum t/11916, thanks @jamiehanslip)
  • Fixed Step Program clipboard paste and shift operations on gated tracks stretching notes to the end of the pattern or leaving overlapping gates behind.
  • Fixed MIDI CC messages on channel 10 being ignored for tracks mapped to channel 10. NRPN was not affected. (forum t/12073, thanks @mplayer78)
  • Fixed the Bank button changing banks while in the Sampler.
  • Fixed Bank+Pad and Bank+F-key navigation from top-row overlay screens.
  • Fixed Live FX A/B button LEDs when entering Live FX from a MIDI bank using Bank+Pad or Bank+F-key.
  • Fixed Record mode exit while playback continues, so gated notes no longer get cut short or left ringing.
  • Fixed gated sounds not always closing correctly on transport stop, song jumps and MIDI Stop.
  • Fixed Bank+Pad navigation cutting off a sustaining gated note.
  • Fixed .LFX file loads not refreshing Live FX pad LEDs and A/B button LEDs immediately.
  • Fixed Bank+Pad and Bank+F-key from a DSP Track Settings page, so the selected bank is reached in one press. Bank+F2 no longer locks the unit.
  • Fixed clicks when changing Envelope Attack, Hold, Decay and Release while notes are sounding.
  • Fixed clicks at the start and end of Multi Mode Loop/Slice slices.
  • Fixed A/B override popups so they now show which parameter was changed, for example ā€œFilter Override Onā€ or ā€œLevel Override Offā€.
  • Improved external-clock sync when the master clock is intermittent or absent. Run/Stop can fall back to internal tempo when no clock is present, Stop works locally while slaved, and the sequencer now stops automatically if clock is lost.

Changes & New Features

  • Assign Sound now remembers each trackā€™s last-used sample folder across save, reboot and project load. (forum t/12010, thanks @sushi2k)
  • The Sampler now behaves more like a dedicated mode. Navigation that would lose an active or buffered recording now asks for confirmation, and visual feedback has been improved during recording and review.
  • Header layout has been improved across Level, Pitch, Envelope, Loop/Slice and Multi Mode views.
  • File picker starting locations have been improved for Plugin / Preset, DSP Config, Live FX, Folder Picker and Browse Files.
  • DSP Mixer page layout now lines up more closely with the Bank Mix page.
  • Live FX pads now use clearer colours by effect family when loaded but bypassed. Engaged slots remain green, empty slots remain dark, and unavailable presses flash red.
  • F5 Loop One Bar now works on DSP Mixer Outputs, Returns/Main and Param Map pages.
  • Bank Mixer pages A-D, Live FX and DSP Mixer pages now show pattern name, length and bar boundaries under the page title.
  • Bank A-D mixer pages now show each trackā€™s output assignment above the track number.
  • Step Edit with Multi Mode on: Erase+Pad, Copy+Pad and F4+Pad now apply to the active Multi Mode track regardless of which pad is pressed.
  • In Sampler Ready, the Rec/Edit LED now slow-pulses as an armed/waiting cue. In Sampler Review, all 8 bank pads light bright green to show a buffered recording is ready.
  • ā€œAct Like Banksā€ for DSP pages is now always on. DSP Mixer and Live FX remain reachable using Bank+0 / Bank+9 on the numpad and the spare Bank+Pad positions past the last sample bank.
  • Added Shift+F2 in the Waveform Editor to toggle Shared Zoom across Multi Mode slices.

S2400_20260529.upd

This update is mainly bug fixes and stability improvements.

A lot of these came from forum reports. Thank you to everyone who posted clear examples and followed up with extra detail.

FIXES

  • Analog Clock In sync now drives the sequencer again. (forum t/12205, thanks @_ceoneezm)
  • Looped non-gated samples no longer click at the end of playback when the loop count is set to an integer (0.0x, 2.0x, ā€¦ 99.0x). (forum t/12200, thanks @mattmars1)
  • Entering and exiting Loop/Slice no longer causes a sudden volume drop when the sequencer is running. (forum t/12195, thanks @_ceoneezm)
  • Switching tracks while inside the Loop/Slice waveform editor no longer causes a sudden volume change on the track you switch away from when the sequencer is running. (sibling of t/12195)
  • On Internal clock, the sequencer no longer accelerates uncontrollably during playback. (forum t/12209, thanks @Djaone2053)
  • Step Program: shifting a multi-event selection no longer resets inherited slice properties on the events past the first. (forum t/12194, thanks @_ceoneezm)
  • Random/gibberish-named folders no longer get created on the SD card when S2400.SET is missing or corrupt. (forum t/7418, t/4679)

## Changes & Enhancements

  • Assign Sound: When Assigning Sounds to empty tracks, the file browser now stays in the folder you last assigned from, instead of jumping back to the SD card root. Tracks that already remember their folder still open there. (forum t/12188/16, thanks @gasparpini)
