CHOMPI WAVE
Beta Firmware 2026
As part of our Open Source release, we’ve included a beta release of a fun firmware exploration. WAVE is an 8-voice wavetable synthesizer that runs on your CHOMPI. Parts of it will feel familiar if you've spent time with TAPE or TEMPO, but it's also its own thing — intentionally stripped back, while still maintaining a bit of CHOMPI flavor throughout.
This is a minimal quick start guide to get you rolling. For more info and access to the development files, visit our Open Source Github.
Released: September 2026

This firmware update CHOMPI: TAPE 2.0 contains new improvements to the signature CHOMPI workflow. In collaboration with Chase Bliss, we created this update to include feature expansions, bug fixes, and firmware stabilization refinements.
CHOMPI TAPE V2.0 Firmware Updates:
Overhaul & Refinements to CHOMPI’s power and battery charging systems
Significantly more robust battery charging protocol
Auto switching to USB-C power mode when a low battery or charging error is recognized
15sec timer (all LED’s flashing yellow) when low battery threshold is reached
Quickly connect USB-C power cable to rescue a low-batt shut down
New User Config Option = Split Delay < & > Reverb
Toggling this setting on CHOMPI’s options.json file will separate the combo Delay/Reverb into two separate FX
When FX split is enabled, the controls will be updated to the following:
Noon = NO Effect
Left = Delay (Green LED)
Right = Reverb (Blue LED)
Shift + Enc Turn = Delay Time and Reverb Size
Refined Tape Stability FX (Flutter/Chorus) to accommodate for a wider range of applications
Updates and improvements to the Midi Engines
Midi CC OUT now sent on all knobs/pages (see midi map for CC’s).
Midi Notes IN now across 4 octaves (adding two more oct on the lower ranges).
Midi Notes IN will continue to play in the “background” while Shift key is held down.
Fixed a mismatch bug related to Midi Notes sending and receiving one Octave apart.
Refined Input Gain Staging for both sampling and looper engines (cleaner, more accurate sample recording).
Updated the bootup oscillator wave to a dual triangle (NES video game flute vibes).
Multiple backend bug fixes and engine optimization / refinement for an overall more stable hardware platform.
