Straightforward mono echo delay with the Korgasmatron II module providing hi and lo cut on the feedback path. In addition a LFO (with a severely attenuated output to produce to correct range) modulates the delay.

Performance controls are provided for mix, delay, feedback, modulation depth, and modulation frequency.

The feedback is restricted to 49% over the full range of the performance control to prevent the feedback/echo growing.

The Hi Cut controls the 2 pole (12dB) low pass filter (side A). 0 = full cut, and 10 = no cut.

The Lo Cut controls the 2 pole (12dB) high pass filter (side B). 10 = full cut, and 0 = no cut.

The Korgasmatron input clipping can produce some nice distortion on the feedback echo, but the feedback level needs to be regined in to prevent the feedback/echo growing.
