This is a nice one, i think: The incoming voltage on In 1 (with attenuation) is compared to the voltage at In 2 (with attenuvertion). The In 2 is normalled to 8V, so you can compare the incoming voltage to a manually set level from -*V to +8V, due to the attenuvertion control at In 2.
From the result a Gate, a inverted Gate, a short trigger, and the sum is created.
Currently the module creates a trigger on the rising AND the falling edge of the gate. By now i am not quite sure if this is a feature or a bug. One could use it to create a swinging trigger from a PWM Pulse. Will have to think about it.
Thanks to the Summing stage this module could also be used as a voltage processor, and/or a 2-in-1 mixer.
