I’m noticing that if I have my audio interface set to 88.2, 96, or anything higher than 44.1/48 while modulating the filter cutoff with resonance below 25% the frequency cutoff will “stick” at the 22000/“wide open” value and then suddenly jump when it’s modulated far enough below the maximum “wide open” value. (it’s only the audio that “sticks”, not the UI) This audible jump happens regardless of what I use to modulate the cutoff; modulation wheel, an envelope generator, LFO, etc. If I switch my audio interface back to 44.1, everything is fine. I’ve only really tested this in a synth zone so far.
I’m on a Mac running Sierra (not the newer unsupported version) and I’ve used a Mackie interface, MOTU interface, and Behrigner interface. Same issue regardless.
