Two classic 1980's #synthesizer recreations for less than $30? And Eurorack compatible. How...?

"A Juno-6 and DX7?"

"In this video I take a look at the AMY board: a tiny, affordable ($29) Arduino-based DIY synth module built around the open-source AMY synth library. It packs USB, an SD card slot, digital and analog audio, MIDI, and CV I/O into a board small enough to fit straight into a Eurorack case.

I go over what the board actually is and what's in the box, then jump into a MicroPython REPL to show how the AMY library's synth, voice, oscillator model works, patching up a simple sine voice, triggering notes, and using the built-in PCM/sample engine and tag-based sequencer to create a basic drum pattern. From there I install it in my Eurorack rack, run through the signal chain (MIDI in from the Hermod+, CV/audio out, self-modulation via CV), and share some closing thoughts on where it's strong, where it's limited compared to something like the Disting NT, and what I want to try next (serum-style bass patches with compression/distortion).

If you've got one of these boards — or you're thinking about picking one up — let me know what you're building with it in the comments.
