The high hat is a set of ring-modulated
oscillators and white noise with both
high pass and low pass controls.  The closed
high hat decay is a preset fraction of the
length of the open high hat decay (roughly
1/10th).  Window works in the opposite
direction of how a high pass filter is normal-
ly configured to work nicely with the window
knob response on other drums.

Open High hat triggered by "Reset" Input
