Breadboard synthesizer: Raspberry Pi, Arduino Uno and analogue low pass filter

Post by handsomegenius »

Hey folks,

I still feel like I'm a beginner with DIY synths, but I wanted to show off what I am learning :)

It's more of a technical than a musical accomplishment. I've got an Arduino Uno set up as a wavetable oscillator, running into an analogue low pass filter with resonance. I put diodes on the resonance feedback to clip it a bit and give it a crunchier sound :)

The Raspberry Pi is running a MIDI sequencer and a short Python script that translates the MIDI commands into lower level instructions for the Arduino.

Tools used:

Seq24 for sequencing: http://www.filter24.org/seq24/
Mido to handle MIDI in Python: https://mido.readthedocs.io/en/latest/intro.html
DZL's the_synth for wavetable synthesis: https://github.com/dzlonline/the_synth

I'm going to look at adding some voltage control to the filter soon!

That looks fun! I haven't played with a bread board since high school electronics class, 25 years ago. Good luck with your creation!
