CHOMPI Club has published the CHOMPI Mk1 sampler’s hardware and software source files, making them available for developers to modify or use as a basis for builds. The release is described as a permanent archive that is unlikely to receive updates, and the company will not provide support for open-source or third-party units. CHOMPI’s artwork and logos are excluded, and owners can still seek normal support for their existing instruments.
CHOMPI Club has released the hardware and software source files for its CHOMPI Mk1 portable sampler, opening the instrument’s design to developers while stating that the archive is a discontinuation release and is unlikely to receive further updates. The files give technically experienced users material to study, modify or use in their own builds, but the company says it will not provide customer support for open-source projects or CHOMPI units made by third parties.
The CHOMPI Open Source Reference Hub links to the original source files for the Mk1’s hardware and firmware. The hardware files include schematics, a bill of materials, EAGLE PCB files and a fabrication package, along with enclosure panel and laser-cutting files. The repository also contains firmware for TAPE 2.0, the sampler software supplied with CHOMPI, and TEMPO 1.0, described as a pattern generator.
The release includes WAVE 1.0, a beta wavetable-synthesizer firmware. CHOMPI Club describes WAVE as an eight-voice instrument that runs on CHOMPI and says it is also intended as a starting point for people writing their own firmware. The archive includes factory microSD card profiles for TAPE, TEMPO and WAVE, as well as a bootloader beta that the company says was not shipped on units; shipped instruments use bootloader version 6.2.
CHOMPI Club says the files can be copied by cloning the repository into a user’s own GitHub account. It warns that the material is intended for developers familiar with Daisy and open-source projects, including people able to work with C++. Beginners who simply want to customize their instrument can continue to use the existing CONFIG Tool or format their own samples, the company says.
What the Files Let Developers Change
Publishing the source gives technically capable users access to the design materials behind the instrument, rather than limiting them to the firmware and hardware configuration supplied by CHOMPI Club. Developers can inspect the circuit design, fabrication files and code, and may adapt the project or use its firmware as a base for experiments. The WAVE beta adds a specific route for exploring a different instrument mode on existing CHOMPI hardware.
The practical scope is limited by the terms of the release. CHOMPI Club says there will be no comprehensive support for open-source projects or third-party-built units, so users taking on modifications will also take on much of the troubleshooting. The files omit the company’s artwork and logos, and the company asks people building their own hardware to use a different name to avoid trademark issues. The release opens technical materials, not the CHOMPI brand identity or a commitment to maintain every project built from the files.
For current owners, the announcement does not end ordinary product support. CHOMPI Club says it will continue customer support and repairs for existing CHOMPI owners through its support channels. That distinction matters: the open-source archive is aimed at independent development, while repairs and questions about original units remain within the company’s normal service offering.

A Final Archive for CHOMPI Mk1
CHOMPI Club frames the release as the final chapter of this version of the instrument, rather than the start of a maintained product line. The site says no more of this CHOMPI design will be made and that no new CHOMPI models are currently in the works for the near future. It adds that the instrument’s spirit may continue to influence future projects, but does not announce a successor or a development schedule.
The archive is described as a permanent source for files and documentation, but CHOMPI Club says it will likely not receive updates. This means the published repository reflects the source materials the company chose to release, not an ongoing promise to revise documentation or firmware. The company also maintains a community discussion space in the CHOMPI Open Source channels on the Chase Bliss Discord, while making clear that discussion there does not amount to official technical support.
The release covers the CHOMPI Mk1 and its associated materials. The company says all CHOMPI artwork, graphic elements and logos were removed for copyright reasons. Its FAQ says independent builders may make units to a degree, but such units will not be supported and may not use CHOMPI trademark branding or the CHOMPI name.

Limits on Builds and Future Updates
The release page does not set out a detailed license summary in the supplied material, so users should check the repository’s license and file-specific terms before redistributing or commercially using modified designs. It is also not clear how much the community discussion channels will be able to help users troubleshoot projects in practice; CHOMPI Club says they are for discussion, while disclaiming comprehensive support.
The company says the files will likely not be updated, but does not specify whether any future corrections or additions are ruled out entirely. It has not announced a new CHOMPI model or a timeline for other projects. The practical availability of parts, the cost and difficulty of building hardware, and compatibility of user modifications are not detailed in the announcement.

How Users Can Continue
Developers interested in modifying the instrument can access the repository through the CHOMPI Open Source Reference Hub and clone the files into their own GitHub account. People considering a hardware build should review the schematics, bill of materials, PCB and enclosure files, and confirm the applicable license terms before proceeding. CHOMPI Club says users who encounter problems can restore a CHOMPI to factory settings using the bootloader and TAPE 2.0 card profile.
For community discussion, the company points users to the CHOMPI Open Source channels on the Chase Bliss Discord. Existing owners who need repairs or product support can continue to use the company’s normal support page. No further repository update, new model or official development milestone has been announced.
