I own a Twin Peak Resonator made by Klangbau Köln based on Rob Hordijk’s Twin Peak filter. Such an excellent module, it’s more than a filter/resonator, it’s a fantastic sound source (wood percussions, sub basses, bass drum, fm clusters, etc) I could buy a second one but before I do, I’d like to know if it’s technically possible to emulate it in a custom unit made for the ER-301.
On top of that, Klangbau Köln’s version also has a very useful FM knob called XFM, Filter 2 modulates Filter 1, for FM
I’m reading about the custom units and middle layer SDK on this forum and I’m wondering: Do you think it’s possible to replicate this Twin Peak Resonator with the ER-301 ? I could try this as a first “custom-unit” project but before I try, according to the following schematic, do you think it’s technically possible to do this with the 301 ? Don’t you think it would be too CPU intensive ? (The module uses an analog path and a 301 version would probably not sound the same but that could be fun…)
