Arduino synthesizer with a 1-octave capacitive touch keyboard

DIY audio synthesizers are not new. We have seen before some really cool synthesizer builds using Raspberry Pi and NXP LPC1114FN28 ARM. Here comes TinyTS, an Arduino-based credit card sized (100x65mm) synthesizer. It is a fully open-sourced design with a 1-octave capacitive touch keyboard.

The synthesizer parameter knobs includes:
DCO: Coarse pitch and Double. The CV out follows the keyboard and coarse pitch.
DCF: Filter peak and ENVmod.
ENV: Attack and Release affecting amplitude.

Here’s a demo video showing the TinyTS in action.
