We are pausing the sale of synthesizers and any accessories. For more information please visit the pause.

We learned so many things during this design iteration and it's time to use those to make the next design steps. Thank you to everyone who has and is participating in the beta! Anyone who has purchased this beta unit will be eligible for an upgrade path to the new design. Sign up to stay in the loop.



21st Century Musical Instrument. Modular synthesizer with MIDI Control, 4 Joysticks, 4 OLEDs, and 8 Knobs. Use existing patches on the SD card, or create your own on Mac/PC/Linux.

What's in the box

This is an upgrade kit for people who already own an Axoloti Core. We're including an adapter board and a Female and Male header in case you've already soldered one or the other onto your Axoloti Core.

This kit will not generate sound unless you already have an Axoloti Core.

Assembly instructions:

Welcome to the beta!

When you open the box, you'll have a 21st century musical instrument. Connect a MIDI or USB Midi keyboard and start exploring. Each Wanderlust ships with an SD card full of awesome synthesizer patches. You can change synths without programming, using a menu system or by swapping SD cards like a video game cartridge. When you're ready to start designing your own synth models, you can connect to your Mac/Win/Linux computer and make sounds that no one has ever heard before!

We ask that as participants of the beta, you hang out a bit with the community and give us your honest thoughts about the synthesizer as you're starting to play. Photos, videos, and conversation are encouraged. We will also be holding forum-only give-aways and discounts when new versions are released.

We're here to figure out what parts of the synth work, and what parts need adjustment. We're going to be keeping track of bugs and features on the beta workboard.

We also want to remind you that Axoloti has a wonderful community if you want to ask a question about the Axoloti Patcher or the Axoloti Core hardware. 

Free as in speech

We want to make sure that you are aware that you can buy all the parts for this synthesizer and solder all the components together without giving us a dime, because open source is the great big idea that can change the world.

We also think that buying a synthesizer from us is also pretty cool.

      Estimated Timeframe  

      The next batch of synths will be ready to ship December 18th, but we expect those to sell out quickly. After that we will be releasing new pre-order batches monthly.

      We're going to be communicating updates via the beta blog and into your inbox if you order.

      Risks / Challenges / Caveats

      Our team is led by an Electrical Engineer with 18 years experience leading, testing, designing, manufacturing, marketing, and supporting electronics in the fields of electric vehicle energy systems, avionics, semiconductor test, and startup IoT industries. We have a vast network of engineers, developers, artists, and musicians in the Chicago and professional community, and believe me, they have been called upon and have given this project their love.

      Because this is not our first rodeo, we can guarantee something will go wrong. We're at the stage where we're sure everything works when it goes out the door, but it's engineering. We're going to use the community forums to capture problems and communicate solutions. We're here to find the problems and make them right. We ask you to be patient and work with us to build something new and wonderful.

      We have designed the hardware and equipment with industry best practices and do not expect any possible harm to connected devices such as computers, however we encourage an abundance of caution and recommend that you use a USB hub/switch to firewall your computer from the beta hardware.


      If you have a question that hasn't been answered here, head over to the forum, or ask us a question.
