So this evening I decided to hear the pedal “sing” by goosing resonance into self oscillation.
Very cool 
- BUT more interesting still is how Spin affects the frequency of note which is created by the Resonance parameter (I’m referring to the pure audio, not the synth).
It is not the same (it sounds like1 octave higher?) and depending how the Spin command is set, the second note will appear in a different part of the soundstage AND it will be offset in time as well (you can this create interesting rythmic noisescapes).
