This was originally developed as a timing accessory for a sequencer Ken was working on, though when fed from a VCO, interesting frequency trills like those of the old 8-bit computer games can be produced. Feeding the control voltage from a Psycho LFO produces some interesting effects.
There are two outputs, one [PULSE] is a narrow "trigger" pulse, the other [PWM] follows the pulse width of the incoming signal. This means that any mark/space ratio sweep being applied to a VCO connected to this module, will also be on the output signal of this module.
