There are many ways to describe the YEP. My favorite is the “clock wrecker” but it is probably more accurate to call it a “gate burst generator.”
The internal clock (square wave LFO) enables/disables a bank of 3 additional Square wave LFOs with the intent of having things start and stop on time (thanks to the clock) but allows for some chaos in the middle.
There’s an output for each LFO, and the clock. You can also substitute another wave in for the clock signal. I am partial to a nice long envelope.
YEP is 8 HP and 800 FUN.
