DOOM OS Patcher

Changelog

0.6.2-alpha, build 3824 (2026-10-06)

Fixed

  • The AUTO TRIG shortcut no longer freezes the box on MARK

Improvements

  • The patcher shows the checksums of the stock firmware and patched firmware

0.6.1-alpha, build ED5E (2026-10-04)

New

  • Pattern Follow (autoscroll) can be toggled with SHIFT + HOLD
    The pattern will stay on the currently selected measure or follow the playback head.
  • Solo is now mapped to SHIFT + ROLL
    The ROLL button blinks when solo is active.
  • The metronome can be activated with SHIFT + PAD 9
    Press once to toggle default metronome behavior (active during playback), press twice to toggle recmode (only active during recording)
  • EXT SOURCE can be toggled with EXT SOURCE
  • Time signatures visible in pattern menu
    Currently only show the time signature, the ability to change it will be added at a later stage.

Fixed

  • Playback of a new pattern with empty tracks is now supported
    This allows you to rehearse and record with a running metronome. Previously, an empty pattern was not playable, and adding empty tracks to the pattern would get them removed. This issue made it impossible to record patterns without creating a track with at least one note in it first.
  • REC button flickering fixed
  • Various smaller bugs involving edge cases

Improvements

  • REC button dimmed when not recording.
    The REC button was brighter than on the stock firmware, which could lead users to mistakenly assume REC mode was enabled.

Miscellaneous

  • The pattern mode now supports various time signatures internally
    For future stock compatibility reasons.
