The purpose of the Gate Converter is to turn standard positive gate signals into negative to positive going gate signal. This is particularly handy when interfacing to other manufacturer's modules that require a zero crossing signal to operate. It can also be used to convert assorted LFO or VCO signals to square or rectangular waves, to extract some form of gate signal from an envelope and so on.
A little on how it works:
The schematic of the Gate Converter.
This circuit is a basic comparator with a little hysteresis. It is set to detect input voltages above or below the reference voltage of approximately 1.4 volts. The output of the comparator is then reduced by the resistive divider to approximately + or - 5 volts, depending on whether the input voltage is above or below the reference voltage.
There are 4 identical units on the PCB.
