Developer Brian Whitman has introduced the AMYboard, a 10HP Eurorack-compatible synthesizer that lets you load a variety of synths, with digital and analog audio, MIDI, and two CV channels.

The AMYboard firmware runs Micropython, and can be controlled and programmed from your Web browser. You can also use AMYboard in Arduino to create music devices of your own design.

It can act as a sampler, play WAV files, or let you make your own synthesizer setups in code from bare oscillators, effects, and filters. AMY is open-source and runs on all sorts of hardware. The AMY platform already powers synths like the Diapasonix, the Spark, and the Tulip Creative Computer.

AMYboard is intended as a “reference hardware” for AMY – running the same ESP32-S3 as Tulip with 8MB of RAM, but with new features including both analog and S/PDIF (digital) audio input and output, enabling live effects, sampling, and filters. There’s also an SD card for sample storage, and an I2C host port for connecting your own displays and knobs.

Pricing and Availability:

AMYboard is available now for $29.90 USD. It can be powered over USB or a 10-pin modular power cable, and comes with a 10HP laser-cut faceplate.
