I’ve just got my PiSound today and started playing around with it. I’m running it with a RPi4, on the latest Patchbox OS and MODEP 1.8.0.
I tried a few plugins and everything seems to be working pretty well, a part from 2 minor bugs that I reported on github. What also stroke me was that the Harmonizer plugin was not working on my end. At least it was not doing what it is supposed to, though it is definitely doing something, as I can feel that the latency has increased (expected due to the FFT processing). Is it also the case for you?
I checked out this topic, which a few of the plugins, including the Harmonizer, were reported as not working. As this was an old topic and some other plugins on that list are indeed working now, I don’t expect it to be up to date.
