all jumpy, it's the Master knob.
At band practice last night trying to make minor adjustments in my overall volume and the damn knob was jumping all over the place.
Big volume jumps from -12db to 0.0db just by tweaking the knob ever so slightly.
Annoying.
happened to me tonight at rehearsal. it got REALLY loud and I turned it down all the way, then slowly turned it up again but there was NO SOUND..when I turned it up all the way I got sound but VERY low level. then I checked the master section and output was -25 or whatever the lowest number is. haven't seen these 2 parameters with different values before, is this new in 1.06? anyway I tried to match them and ended up at around -18db on both to get the same volume I had before the update through our PA. I always used to have it on -10db

it seems something has changed.
