Hybrid Sid-Style Snaredrum Drumsynth of the TinyRhythm

This is the second of the 8 modules of my diy microcontrolled hybrid drumsynthesizer - the Snaredrum module. It gets a trigger from a baseboard and sends back an audiosignal to a mixerboard. The baseboard wants some midinotes to send triggers to the modules.

Well this one is VERY simple. It consists of a tiny13 microcontroller and a dual opamp, about 2 EUR :-). The 3 pots for Tune, Bend (positive/negative with different speeds) and Soundlength go into the DACs of the tiny13. It directly outluts a squarewave and shifted (tunable) noise. Both audios are blended by the 4th pot and mixed together and buffered.

The cool thing about this: if the bendenvelope is much faster than the soundlength, the values 'wrap around' the 8bit borders of 0 and 255 resulting in multiple BlipBlipBlip-Nintendo sounds.
