I have a Prophet REV2 and the biggest issue for me is that the pulse/square wave works a bit differently than in Syntorial. The manual says if you want a plain square wave you need select pulse and then set the shape mod to 50%. Even then it doesn’t sound exactly right, there’s still a fair amount of buzziness. I’m actually in the middle of recalibrating the oscillators right this moment which is taking forever. In any case, I haven’t been able to get that big fat full sound with it the way it is now.
Okay, recalibrating it seems to have helped. The Prophet REV2’s oscillators still seem to be a bit more buzzy than the ones in Primer, so I had to use a smidge of the filter. These are the settings I found that are the closest approximation I could achieve. Keep in mind I’m just a beginner myself so use your own ear. I just hope this helps speed up the process for someone else in the future.
