Firmware Update Version 1.0.8

Released - Feb 15th, 2024

As we continue to refine the Flagship-Firmware, we will be posting updates both here on our website, as well as our Discord server. We've decided to share these updates in multiple smaller chunks so that everyone can have access to the latest features ASAP.

NOTE: CHOMPI uses its micro SD card to manage firmware updates.
There are step-by-step instructions as well as an updated user guide for the new firmware located in the root folder of the download link.

Added VOLUME and PAN settings to pitch knob

  • The pitch knob now contains a second page that provides independent control over sample volume and pan for each save slot.

Added a new "options.json" file onto sd card for customizing user settings, midi channel I/O, etc...


  • Fixes bug where CUBBI slots will sometimes play the wrong sample.
  • Fix crashes on boot due to battery logfile
  • Tighten up looper envelope, improves issues with initial transients being cut off
  • Fix bugs with USB cable detection on insertion. This could cause the unit to freeze when USB cable was inserted.


Upcoming Features

  • Destructive copy/save mode - for "burning in" current sample settings into new save slot and/or looper
  • Add more global options for user configuration and customization

Future Fixes

  • Copying a sample from looper -> slot changes the volume
  • Infinite loop when using USB midi with both IO turned on
  • Fix bug causing occasional crashes when rapidly copying/saving slots

Later this year...

  • Integrated web app for seamless options file generation



These are the factory sample presets that come with every CHOMPI.
