What changed on the module, newest first.

Changes to the Bitbox Micro firmware patch, newest first. Each entry describes something you would notice: what the module does differently once it is flashed, what the patcher does differently to your files, or what changed in the guide you are reading. None of them covers how any of it is built.

12.3.10-mod — October 2026

  • Loops that really follow your tempo, 24 Live Flip modes to re-cut a loop live, and turntablist skills.
  • Clip modes lock a Clip pad's loop to the clock:
    • Vinyl speeds up and slows down like a turntable, so the pitch rises and falls with the tempo.
    • Jungle stretches like an early-'90s sampler, in a Modern or Old Skool flavour.
    • Key Lock stretches smoothly with no skips, keeping transients intact.
    • Manual sets a pad's own tempo, off the clock, for slow junglist stretches.
    • In Jungle and Key Lock the pitch is free: sequence notes into the pad and the loop plays them, in time.
  • Live Flip modes: 24 ways to re-cut a loop live from one encoder, always in time: repeats, reshuffles, chops, reverse swells and harmonies. The chops find where the sound changes, so vocals and chords work as well as breaks.
  • Hold buttons: Pull Up, Power Down, Brake, Baby Scratch, Roll, Pitch Roll and Freeze. Let go and the loop drops back in time.
  • Three Airwindows compressors beside the stock one: Logical4, VariMu and Thunder. Auto makeup gain is improved, with a new Hot setting.
  • Themes: pick one of five, or roll your own in the theme maker, which shows how readable each colour is.
  • The Character chain and compressor settings survive a power-off.
  • Preset BPM runs from 1 to 255, up from 40 to 250.
  • Lighter on the CPU, same sound.
  • Everything from 2.3.9-mod is unchanged and still there.

22.3.9-mod — October 2026

  • Sixteen Airwindows effects on the master bus, and a pop-up that shows what every CC in the patch just did.
  • The Character chain: four effect slots across the whole mix, each with an Amount, a Tone and four effects. Ports of Chris Johnson's Airwindows plugins, described in depth on the Airwindows site.
    • Destruction, lo-fi and breakage: Pockey2, DeRez3, Ring Mod, Fracture2.
    • Overdrive, warm tube to dirty harmonics: Tube2, Drive, Mackity, Huge.
    • Colour, consoles, tape and a transformer: Channel9, IronOxide5, ToTape8, Coils2.
    • Saturation, smooth weight and density: PurestDrive, Spiral2, Density3, Mojo.
  • Pop-ups: every patch CC shows what it changed, in real units. The clock gets them too.
  • A CPU bar along the bottom of the screen, and a new OSD row that picks the pop-ups, the bar, both or neither.
  • Preset BPM: set a preset's tempo on the module and save it with the preset. With Clk Loss on HOLD, it also captures a clock's tempo.
  • Auto makeup for the compressor on CC 46, so the peaks stay level as you compress harder.
  • Keep CCs, a Settings row that puts your per-pad CCs back after a preset load.
  • Fixed: MIDI notes could change compressor, EQ or delay settings.
  • Fixed in the guide: the EQ comes before the compressor, not after it.
  • Everything from 2.3.8-mod is unchanged and still there.

32.3.8-mod — October 2026

  • Three new rows on the module's own Settings screen, the first additions that are not on a CC.
  • Flip UI turns the screen, touch, buttons and knobs over together, for a module mounted upside down.
  • Clk Loss keeps the last tempo when the clock drops out, instead of falling back to 120. Beat-synced delays and LFOs stay where they were, through preset changes, until a clock returns.
  • ProgChange gains NEW ONLY, which ignores a Program Change for the preset already loaded. A sequencer that resends the same request every pattern no longer reloads the preset and swallows its first notes.
  • All three are on page 2 of TOOLS, Settings, and the module saves them with its own settings. A new settings page in the guide covers each one.
  • Everything from 2.3.7-mod is unchanged and still there.

42.3.7-mod — September 2026

  • A master EQ and filter, which the module has never had. Ten algorithms: a DJ filter, a dual cut, a band pass, a three-band mixer EQ, tone and filter together, a tilt, a notch, a peak, a phaser, and a formant filter.
  • The installation and user guide has been completely redeveloped, hopefully making it easier to take in, and easier to reach just the part you need.
  • Every control is neutral at its centre in every mode, so three centred knobs is an EQ doing nothing at all, and the mode dial can be swept without hearing it.
  • Sixteen of the encoder pushes do something. A kill takes a range out of the mix, an open lets a band stop acting, a slam forces a control to its maximum. All of them momentary, and letting go hands back the knob's own position without a jump.
  • A master bypass on CC 57 takes the whole thing out, and puts it back.
  • Nine CCs, 50 to 57 and 59, on MIDI channel 1 beside the compressor.
  • Everything from 2.3.6-mod is unchanged and still there.

52.3.6-mod — September 2026

  • The module's master bus compressor is now reachable over MIDI. All five parameters that were previously fixed and invisible are on the table: Threshold, Ratio, Attack, Release and Makeup gain.
  • It arrives configured as a glue compressor, close to a classic SSL-style bus compressor recipe — 2:1 ratio, a slow 30 ms attack, a 300 ms release — ready to use with no setup, and adjustable from there.
  • The compressor answers on MIDI channel 1 only, on CC 40 through 45: the five parameters, plus on/off on CC 40. The rest of the patch is per-pad, on each pad's own channel. That is deliberate, so a stray message from elsewhere in a rack cannot move it by accident.
  • Everything from 2.3.5-mod is unchanged and still there.

62.3.5-mod — August 2026

  • Per-pad Delay send and Reverb send, so each pad can sit in its own place in the mix rather than sharing one blend across the whole preset.
  • Per-pad Reverse.
  • Per-pad Envelope Sustain, later extended to reach Clip and Slicer pads as well as the sample-based ones.
  • Per-pad Loop Mode and Loop Crossfade.
  • Five granular controls that had no way to be touched before: Density, Grain Size, Window, Scatter and Pan Random.
  • Global delay Beat Sync, Ping-Pong, Filter and Filter Width, shared across the whole preset.
  • LFO Wave, Beat Sync and Retrigger, reaching every pad type — Sample, Multi-Sample, Clip, Slicer and Granular — not only the ones that had them at first.
  • Per-pad stop for long clips, one pad at a time. Stopping a pad now releases the voice rather than cutting it dead.
  • The whole control set was regrouped onto a cleaner CC map, so some numbers moved even where the control itself did not change.
  • The splash screen stopped crediting 1010music on a patched image.
  • The patcher stopped being able to overwrite a user's own stock firmware file.
  • The Scatter control's threshold now reads on the scale people actually think in, rather than an internal one.
