This is my take on the Mega Percussion Synthesizer designed by Thomas Henry. With many thanks to Thomas who kindly gave me the permission to publish it here for DIY. I have made two minor changes which I found useful. First I added input buffers to all four sections of the circuitry, because this eliminates the influence of the potentiometer adjustment to each other. And I changed the circuitry around the CV input and the impact/noise switch. The CV input is now added to the impact/noise switch, with a neutral middle setting for the original behavior. The locked mode is left out.
Specs and features
- Same as the original
- Runs on +/-15V and +/-12V
- Power consumption around 35mA each rail
