Based on a self excited Bridged-T Filter.

The module contains two independent drum sound generating circuits.
Circuits are turned to produce sounds similar to High Tom and Low Tom drums.

Takes 5 millisecond trigger pulse and outputs a drum sound.
Also compatible with gate signals (second drum sound produced when gate input is removed)

Two control knobs F and Q
F controls the frequency of the drum sound.
Q controls the sharpness.

Due to the nature of Bridge-T filters, the controls do not operate entirely independent of one another.
