Take your gates and generate triggers and take your triggers and generate a gate.

Gate to Trigger section
Takes a gate signal and gives a trigger output on both the rise and fall of that gate. The IN LED will illuminate while the gate input is high.

Trigger to Gate section
Takes a trig signal to start a gate signal and is normalized from the fall output in the Gate to Trig section. The gate length knob controls the gate length. The fall output will generate a trigger at the end of the gate. The OUT LED will illuminate while the gate output is high.
