Introducing the Believotron Wanderlust, both an exciting and innovative sound creation platform, and a solid musical instrument that is open and extensible. 

It does't matter what level of musicianship or technical knowledge; whether you have loads of gadgets or you're frugally evaluating one tool; the Believotron Wanderlust has an exciting journey for you.

21st Century Interface

21st Century Interface

Everyone is different, pick the workflow that works best for you. Use the existing settings and customize to your heart's content, or you can design a brand new way of working with the machine and share it with the community.

Dynamic Control / Dynamic Sound

Every control on the Wanderlust can be routed to any part of the synthesizer model, to configure the machine exactly how you want it, flipping between settings with ease. 

It's the flexibility of modular synthesizers, but with the magic, speed, and accelerando of a microcontroller.

Dynamic Control Routing

Change the target of any control.  Use a knob to adjust an LFO and with the tap of a button, that knob can be reassigned, cycled, or toggled to any control in the patch. Swap out one control, a row, or the entire UI. Learn more > >

Control Sequencing

Program / sequence / record / loop values for any parameter. Layer. Raise the attack on the start of every measure, lengthen the release at the end. Build emotion and expression into your sound. Learn more > >

Sequenced Control Routing

Change how the controls are routed in time. Start by setting up the knobs to control Attack / Decay / Sustain / Release. The sequencer can automagically change the knobs to control phase / chorus / echo / flanger during certain bars / measures. Learn more > >


Add expressiveness make your sounds more dynamic. Record pad taps, knob turns, and joystick jostling, live. One-shot / Loop / Toggle / Timer-Counter playback for the perfect dramatic punctuation or emotive texture. Modify recorded values on the fly either overwriting or returning back to the recorded value. Program in your perfect performance and then push the edge on every playback. Learn more > >


Create new instruments that can quickly change states and become more mellow, more abrasive, more muted with the touch of a button. There are plenty of knobs, but often you'd like to turn five of them at once. Like wailing hard on a saxophone, quickly pushing your instrument to extremes expands the dynamic creativity.

Creative new ways to play

Creative new ways to play

Discover and create a whole new world of sound. Creative orchestras, strange new instruments, impactful installations. Use motion, light, and even sound itself to control the instrument. Translate those into physical motion and add to the wonderful genesis of new art.

Audio by Axoloti

We have so much respect for Johannes Taelman and his open source project, Axoloti. We found many wonderful audio engines during prototyping, but I wanted to go on just ooooone more search before settling on a particular solution. I couldn't have been more lucky in my entire life. We went from working on a single rigid synthesis engine that required reprogramming to alter the controls to a fully graphical programming system that incorporates the magic of arduino-like functionality.

Maker Hardware Friendly

Maker Hardware Friendly

The Believotron Wanderlust has survived an epic slew of brainstorms on how to connect to existing open hardware platforms. Literally any platform that has 0.1" center pins will be able to interface with both the Believotron Wanderlust and the Axoloti Core hardware. We've implemented the three most ubiquitous / informative platforms. Raspberry Pi provides the most advanced processing platform. Arduino / Genuino offers the largest number of projects. Adafruit leads in informative, respectful, and creative projects. We've created a relatively straightforward workstation with expansions for you to create mind-bogglingly weird controllers, or the most modern and new workflow imaginable. Motion, acceleration, light, heat, images. Leverage the extensive open community and participate in the party!



Pleasure Engineering

Independently, we feel the calling. We all remember the first time we fell in love with a sound machine and got lost in the twisty little passages, all alike. Hours would pass, grey matter would be throbbing with new connections. Neurons that fire together play together.

It's that feeling of wonder and discovery that draws us all to a lifestyle of synthesizers, gadget-boxen, and transcending electronics to provide the sublime.

Believotron is dedicated to designing open creations that delight. Not just Diet-Open with a handful of files released, but full assembly drawings, part-numbers, machine descriptions, and process documents. We think that the tools released last year are thousands of times more capable than tools released a decade ago and we would like to contribute to the accelerando. 

Our senior engineer has been at it for 17 years. He's shipped well over a billion dollars of hardware: a garage door on a 747 for the NASA SOFIA project (Psst we found oxygen on Mars), Semiconductor Test Equipment (Your cell phone, your car, your toaster, your...), Electric Vehicle Battery and Fuel Cell test, and several start-ups in security, transportation, and communication. Daniel balances his obtuse creativity with a strong desire to create quality hardware and documentation and is looking forward to setting a new standard for open hardware reuse and interoperability.

Our network includes Electrical Engineers, Mechanical Engineers, Manufacturing Engineers, Actors, Writers, Artists,  Chicago, SF, NY, Austin, Salt Lake, Belgium, Shenzhen, Shanghai, Taipei (Saved best food for last #NightMarket)
