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.
More details can be found here.
Here’s a demo video showing the TinyTS in action.
