I installed Dune 3.4 on my iMac running High Sierra, Logic 10.3.4. The filter cutoff knob sporadically goes up and down with every patch in a jerky motion.
Even the visual keyboard displays notes that I didn't press continually moving like it was playing a sequence. This happens on all of the factory patches. When the cutoff moves up and down, it cuts off the sound; (when it goes down to zero of course). Any ideas?
