BB glitch

I am a bit adamant upgrading to 4.0 because of other user’s feedback so staying with 3.9 for now. I have noticed some glitching with the volume levels (having a mind of its own, which wasn’t really a big deal for me until now). I have also noticed one time my BB completely froze when I tried to switch drumset types via MM. Would appreciate any feedback from other users…thanks in advance!
