Module contains two independent percussion sound generating circuits

The module contains two independent percussion sound generating circuits.
Circuits are tuned to produce sounds similar to a clap sound and snare drum.
Based on a self excited Bridged-T Filter, with digital white noise.
Takes 5 millisecond trigger pulse and outputs a drum sound.

Two control knobs D and F
D controls the duration of the release of the generated sound, adjustable from a quick hit to a long roll off.
F controls the frequency of the percussion sound, from deep and low to snappy and high.
