The Tiny TS is a credit card sized (100x65mm) fully open-sourced synthesizer with a 1-octave capacitive touch keyboard.

It has Audio/CV/Gate outputs and 6 synth parameter dials. The CV’s output 1V/oct and Gate from the 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.

The synth is built on the ATmega328 MCU and is very easy to build as a kit.

The synthesis method is "Resonant Peak Modeling".
It modifies 2 sine waves to simulate a resonant low-pass filter.
This is similar to FM synthesis.

The DSP code runs at 35.5Ksps or 35481KHz samplerate.

It runs from 6 – 12v (9v battery) but can run down to 3v as well but the CV 1v/oct output is dependent on a 5v supply to the chip.

Risks and challenges

This is Open-Source and DIY and both circuit-diagram and code will be available to do your will.

But to build it a PCB is still needed so the funding will go to PCB manufacturing and part ordering for the kits.
