CHOMPI is now
Open Source!

We’ve decided it’s time to discontinue CHOMPI. We won’t be manufacturing any more units, and instead are Open Sourcing the files for our CHOMPI Club Community to keep exploring.

Our team put together a video to chat through the process, give some insight, and bid farewell to this little friend.

What does it mean?

We put together a whole hub of CHOMPI Open Source info to dive into. But the TLDR version is this:

In short, the manufacturing landscape for CHOMPI has changed significantly (as it has for many small instrument makers). It was becoming too expensive and time-consuming to find a way to build CHOMPI that would still be compatible for current customers. So we’ve decided to discontinue CHOMPI, but make it open source so that the community can continue to explore and build on the platform.
- firmware/chompi-tape: TAPE 2.0, the sampler firmware every CHOMPI ships with.
- firmware/chompi-tempo: TEMPO 1.0, a pattern generator firmware — the counterpart to TAPE.
- firmware/chompi-wave: WAVE 1.0, a wavetable synth firmware that doubles as a starting point for anyone writingtheir own firmware.
- firmware/chompi-bootloader-v6.4-beta: The bootloader. Never shipped on units, which run v6.2; created to improve stability.
- firmware/card-profiles: The factory microSD card contents for TAPE, TEMPO and WAVE — firmware, samples and settings.
- hardware/hardware-pcb: Schematic, BOM, EAGLE PCB files, and the full fabrication package.
- hardware/hardware-enclosure: The six PCB panel enclosure files, as well as laser cutting files for DIY panels.
Open source files all live on our CHOMPI GitHub
- The Open Source page will walk through important details. There is also a quick link to download the CHOMPI WAVE beta firmware too.
- We are not providing customer support for Open Source projects, or CHOMPI’s developed / made by 3rd parties. Check out the Open Source channel for community discussion on our Chase Bliss Discord.
As we close this chapter of manufacturing for CHOMPI, this is a hand-off to the community.
- We will continue to provide ongoing support for CHOMPI customers.
- We will be hosting the conversations on our Chase Bliss Discord, but not providing support for Open Source projects.
  - It’s up to you now.
- We won’t be doing repairs or support on any CHOMPI’s not made by CHOMPI Club or Chase Bliss.

So what does this all mean for the future of CHOMPI?

This doesn’t mean we’ll never make something in the CHOMPI world again. We really do love this little pal, but for now this chapter feels complete.

Key info to know:

Number one on a peach-colored background

This is the final run of this version of CHOMPI. Once the stock is sold out, it will be officially retired. We currently have a small handful of CHOMPIs left at the Chase Bliss hubs the US, EU, Japan, and Australia, and won’t be re-stocking once they’re gone.

We’re carrying the ethos and passion for self expression behind CHOMPI into new projects we’re working on at Chase Bliss. We love our customers, and will continue to support past and current CHOMPI owners. We’re just not making any more of these.
That is a big part of why we Open Sourced CHOMPI. It’s been something we’ve wanted to pursue since the early days of CHOMPI, but some development and manufacturing limitations complicated that endeavor. Which is why we’re pretty jazzed about being able to open this up to the community now. CHOMPI exists largely in part from the support of our music, art, and education communities and we’re really happy we can pour back into those spaces. Our hope is that this provides pathways and foundations for students and educators to explore what's possible, and hopefully inspire the next generation of developers and instrument makers.

Our CHOMPI Club community is still active on the Chase Bliss Discord and you are welcome to join the fun!

Short answer: YES! We are continuing to provide customer support, repairs, and questions as normal for all past and current CHOMPI owners. We’re still facilitating repairs at our Chase Bliss hubs, and we care about helping people enjoy their CHOMPIs for years to come.
We’ve merged CHOMPI Support into the Chase Bliss ecosystem. That means all CHOMPI owners now have international support, and it will be faster and easier than ever to get help. We care a lot about our CHOMPI pals, and this will make your support experience even better.
All support (questions, repairs, etc.) are being handled by us and our Chase Bliss teammates! If you need help, feel free to submit a Support Ticket or email us at chompi@chasebliss.com
We’ve also transitioned our original CHOMPI Discord over to the Chase Bliss Discord, and we’ve made some new resources to help you along the way!
*Important to note: we will NOT be providing comprehensive support for Open Source projects however. We won’t be able to repair or support any custom made CHOMPI replicas or firmwares not manufactured by us.
If you create something new using our Open Source files, that’s awesome! But just know, that is now up to you to support.

From the very beginning, CHOMPI has been an unconventional and often wild ride. We feel so grateful to everyone who has joined us on this journey, who supported our Kickstarter, welcomed us into the Chase Bliss world, got excited and inspired to make music with us, and taken CHOMPI around the globe to places we never imagined possible. If you’re reading this, you’re part of the “Club” and we’re glad you’re here.
We’re still here, we still love our CHOMPIs, and love seeing the myriad of creative things you all do with them. CHOMPI isn’t dead, just evolving and growing into new spaces. Thanks for supporting us, we’re excited to bring you into the next chapters.
Big love friends,

A quick peek at our story.

As electronic music enthusiasts, we endeavor to craft inclusive culture and empower new learners, making the world of sound design more accessible to a larger audience.

What started out as a personal journey to explore a more experimental form of music, grew into a community program, an education initiative, and now more than 10 years later has evolved into a unique musical instrument platform.

MARCH 2023

CHOMPI Kickstarter
In March of 2023, we launched our Kickstarter campaign for CHOMPI. It unexpectedly went viral and we hit the ground running! That 1st batch of CHOMPI's started shipping out 9 months later in December.
JANUARY 2024

CHOMPI Launch + Meeting Chase Bliss
We launched our web-shop and started offering CHOMPI worldwide at the beginning of the year. That same month, we happened to meet our pals at Chase Bliss during NAMM. They host an awesome Pedal Market at Windsor Browns, and you should definitely check it out.
MAY 2024

SuperBooth24 Collab
Over the course of just a few months in early 2024, the CHOMPI team and Chase Bliss crew quickly became fast friends. What started out as a low-key convo around our complementary products, evolved into a collaboration for SuperBooth2024… naturally progressing into our fun little partnership for Treasure Island 🌴
JANUARY 2025

Joining Forces
We've spent the last year growing our CHOMPI Club community, and being inspired by all of the creative folks we've met along the way. Our friendship with Chase Bliss has continued to grow into an incredible opportunity to join forces in a more permanent way and we couldn't be more excited!

SUMMER 2025

SuperBooth 25 & Bliss Fest
We spent the early spring and summer beginning to merge CHOMPI world in the the Chase Bliss ecosystem, and continued to collaborate on more ways to help folks discover how exciting CHOMPI and effects pedals can be together! We joined the fun at SuperBooth 25, and CHOMPI has been popping up at lots of music events and demos through out the year.
In August, Chase Bliss hosted their first ever Bliss Fest in Amsterdam. We were so thrilled to create a whole CHOMPI experience and workshop for our CHOMPI pals in the EU.
NOVEMBER 2025

Launched CHOMPI through Chase Bliss

We officially launched CHOMPI for sale through Chase Bliss! This included a special Limited Edition Storytime CHOMPI with a translucent white enclosure and fun nod to our journey in the panel graphics.
Our pals at Chase Bliss also made a mini-doc about our CHOMPI journey. This is our first big project that we’ve done as a team and it felt like the right time to talk about everything we’ve experienced to get here. It’s quite a story, and we’re so thrilled to be doing it together now.
MARCH 2026

New TEMPO Firmware
TEMPO is essentially a rhythmic reimagining of CHOMPI. Whereas the original firmware – that we’re now calling TAPE – was all about fluid, free-form, “tape” style composition, TEMPO is the complete opposite. It’s all about making patterns.
The workflow and feel are still familiar and very “CHOMPI,” but otherwise it’s essentially a brand-new instrument. It’s free for anybody with a CHOMPI and pretty easy to update.

SEPTEMBER 2026

CHOMPI is now Open Source
As this original CHOMPI reaches it’s final chapter, we are Open Sourcing it to share with our community and open up opportunities for students and educators to develop their own instruments. Once units are sold out on chasebliss.com , that is the end of this CHOMPI. We will continue to support CHOMPI customers with repairs, tech support, and answering questions for any CHOMPI’s originally made by us.
From the very beginning, CHOMPI has been an unconventional and often wild ride. We feel so grateful to everyone who has joined us on this journey, who supported our Kickstarter, welcomed us into the Chase Bliss world, got excited and inspired to make music with us, and taken CHOMPI around the globe to places we never imagined possible. Thanks for supporting us, we’re excited to bring you into the next chapters of this adventure. Big love friends,
