Bitbox Mk2 Custom Firmware Overview

video upload by Ville Walveranta

"I created a custom patch for the official 2.3.4 firmware that adds a screen saver, speed change without pitch change, vertical waveform zoom, and an easy way to reset parameters to their defaults."

Additional details via the developer:

"I’ve put together a free, unofficial customization of 1010music Bitbox MkII firmware 2.3.4, adding a few features I’ve wanted on my own module. The customized version identifies itself as 2.3.4+c.

What’s added:

Vertical waveform zoom: pinch/spread vertically to adjust waveform height from 25–3200%. This makes quiet samples easier to see and lets you shrink loud waveforms. Horizontal zoom still works normally. A stationary two-finger tap restores 100% vertical zoom and horizontal fit. This only changes the display, not the audio.

Optional screen saver: a black screen after 1, 2, 3, 5, 10, 15, 30, or 60 minutes of inactivity. It’s disabled by default, under Tools → Disp. Playback continues while blanked. The first touch, button press, or encoder movement only wakes the display, preventing accidental edits.

Optional MIDI/CV-trigger wake: choose MIDI, CV triggers, or both. MIDI clock and active sensing are excluded. Unlike physical wake controls, the first incoming musical event still performs its normal action.

Pitch-preserving Speed: 50–200% playback speed, with a dedicated SPEED dial on the Sample-mode LFO/Spd page. It supports live adjustment and the normal INFO modulation editor, including LFO/CV modulation. At 100%, it uses native playback.

Double-tap dial defaults: double-tap a numeric dial to restore its default base value. Modulation sources and amounts remain intact.
