Digital Hi-Hat Module
This is a PIC based percussion module which is loosely modeled on the hi-hat. It features seperate Decay and Pitch controls for Open/Close modes and a master Shape control which mixes between a linear or logarithmic decay. This module is also compatable with the BMC003X Expander for using external CV for all of it's parameters.
