So I have ME on two different computers, and recently, the two opacity features haven't been working when I recently tried to remap my midi (APC40) sliders on the program. I've tried with two other midi controllers, and on my other computer and it still won't seem to work on either computer. It used to work for me previously, but randomly stopped working and hasn't worked since. I'm not sure if I'm doing something wrong. Any advice is appreciated, thank you :)
