Made a synth for $75* ! (*excluding tariffs/postage...)

video upload by Guinan

"I made an open-source Raspberry Pi based DX-emulation synth for around $75 and hooked it up to my Novation Circuit Tracks.

MiniDEXED is the open source DX emulation project,

I used the following open source hardware Raspberry Pi HAT which delivers a DAC and DIN MIDI in and out, https://github.com/tebl/BulkyMIDI-32

Build is also here, https://www.pcbway.com/project/sharep...

I ordered mine pre-built from Ebay - but that's just a reflection on my soldering skill!

To run the software it also needs a Raspberry Pi Zero 2 (buy one with a 'GPIO header' as then it's just plug and play once you have loaded the software from the above link). Make sure it's a 'Zero 2' as the older model is much slower.

Much more detail and slicker presentation here....
• MINIDEXED - honey, I shrunk my DX7 collection [posted here]

All of the above work was inspired by the very excellent and similar MT32-pi project by Dale Winham which emulates the Roland MT-32 synth and others. I've got a 2nd Pi Zero 2 and some parts in the wings for a further video...."
