Chase Bliss has released the CHOMPI Mk1 as a discontinuation open-source package: complete firmware and hardware source files are available on GitHub. The release includes TAPE 2.0 sampler firmware, TEMPO 1.0 pattern-generator firmware, a WAVE 1.0 beta (an 8‑voice wavetable synth) with a downloadable beta card profile, a bootloader v6.4 beta, factory microSD card contents, PCB schematics/BOM/EAGLE files, and laser-cut enclosure panel files. The WAVE firmware is a deliberately stripped-back but playable synth exploration; the materials are intended for developers comfortable with Daisy hardware and C++ who want to build or modify CHOMPI firmware and hardware. Casual users can still use the existing CONFIG TOOL and sample formatting workflows to customize their units without diving into code.
This permanent release will not receive further official updates and Chase Bliss will not provide comprehensive support for open-source projects or third-party CHOMPI units, though standard customer support and repair services remain available for purchased CHOMPIs. All original artwork and CHOMPI trademarks are excluded from the release; builders are required to rename and avoid using trademarked logos if they produce their own hardware. The company directs community discussion and troubleshooting to dedicated CHOMPI channels on the Chase Bliss Discord for peer support.
