I’ve used this app for a number of years but just came across this bug. After adding portamento to a patch I tried (multiple times) to save it as a scene. After it “saves” the portamento setting is at 0. I’ve tried saving it as a new scene, overwriting an old scene, changing the sound font, and everything else I could think of but nothing saves the portamento setting. This is not the on/off setting (that gets saved) but the amount of portamento. Why is this?
