Auduino Synth build for the Arduino Nano

In my recent LIVE from the Lab Youtube stream, I built up an Auduino Granular Synth using an Arduino Nano and a handful of parts. You can watch the VOD of the session below.

This is a relatively simple (but extremely fun) project that demonstrates how quickly you can build a fully functioning Synth and control it with Midi. **NOTE - This project uses old school 5-Pin Midi only so you will need a Midi interface to connect it to your PC**

Download the code and schematics HERE and follow the video for the complete tutorial. Enjoy!!


  1. Hi Dave, first of all compliments on your work - it is inspiring. Whilst looking for granular VST's i stumbled over the Auduino video and decided to pick up this long lost skill. My components are on order and as i am getting to grips with the code (i am still from the Basic+ era) i was wondering if you could make the auduino switchable between stand alone and midi triggered by means of a pushbutton or switch. It would greatly add to the versatility of this instrument. Thanks in advance and thumbs up from the Netherlands. Sef Spee

  2. You are great. If you hadn't realised this tutorial I would have had to buy a 300€ synthetiser and it's toooo expensive. Thanks you for all and I hope you are fine.

  3. should the output cap be 3.3nF like you say in the video? On the schematic it says 33nf

  4. Hi Guy
    Compiling with Arduino Ide I have something wrong in diagnostic:
    “Use of undeclared identifier ‘DipSwitch’
    Use of undeclared identifier ‘NoteOn Midi’
    Use of undeclared identifier ‘NoteOff Midi’
    Use of undeclared identifier ‘Pitchbend’
    Use of undeclared identifier ‘ShiftLeft’
    Can you answer me why?

  5. The next time I read a blog, I hope that it doesnt disappoint me as much as this one. I mean, I know it was my choice to read, but I actually thought you have something interesting to say. All I hear is a bunch of whining about something that you could fix if you werent too busy looking for attention.
