The 2hp module has since been returned. I still have the Pittsburgh. The source is the saw and pulse outputs of the patchbay of my moog mother 32. After the delay, the signal is fed back in through the external input jack with the moog mix knob set accordingly.
With the delay mix knob set to dry, the sound comes through just the way the moog made it. In all degrees of a wet mix, you begin to hear the distortion. It ranges from barely noticeable at short delay times, to like a pw modulation type effect at long delay times. I do hear some familiar sounds when the delay time is moved back and forth.
I have tried all logical settings for each knob involved and then some.


A month ago I bought the 2hp delay module. The best I could get from it was a blurring of the sound, whether I applied cv to the delay time or not. I figured it must be a result of buying a cheap piece. I just hooked up the Pittsburgh Modular lifeforms delay and I got the same thing. Internet searches have revealed that no one has ever encountered any problem with a delay module whatsoever. This is frustrating.
