Arduino MEGA was used for the drum machine and Arduino UNO for the synth module with a MIDI input. Both are enclosed in a “groovebox”. Output through PWM, 8 bit resolution, 31372,55 Hz sample rate. I have to thank the authors of Auduino. My project started from it and here is the result.
Documentation (only in Slovene) and source code are available on my web page http://www.mitjacerkvenik.com , you can find them under Projects. Please donate so I can take some time to translate documentation in English. Thanks!
I’m constantly amazed by what you can do with the Arduino platform. Via the excellent Matrixsynth.
