DSM 03 module for Karplus-Strong synthesis
"We took the feedback feature originally in the Evolver (also on the Pro 2, and Prophet 12), the idea is you have a tuned feedback loop that takes the audio output, runs it back through the analogue filter, and then through a delay line... so you can do Karplus-Strong synthesis with it, or you can just use if for mangling sounds" - Dave Smith
