The Tiny TS – A DIY Touch Synthesizer

November 28, 2016


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.

If you don’t like the onboard sound of the synth, the CV’s output 1V/oct and Gate from the keyboard so teams well with my other oscillator chips.

This will be this christmas DIY kit to play with.

The synthesizer parameter knobs are:
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.

And it will be cheap:
$20 for the PCB only.
$30 for PCB and a preprogrammed chip.
$50 for full kit with all the parts.
$60 prebuilt plug&play.

The Drum8 Goes Open Source

September 26, 2016

The dsp-D8 is a great drum chip with its 8 voice polyphonic playing capabilities. But the 28-pin DIP can be quite large for DIY projects.

The Drum8 is much smaller with a 14-pin DIP footprint hosting still the same 8 voice polyphony adding a global pitch CV and a true analog accent input.

The trigger inputs has change to rising edge detection and it now runs on the ATtiny84.

And the best of all,
It goes open source this week with the code posted here in the right side menu.
