I think this is strongest point of bm3. It is annoying though when the screen pops up to change mixer volume it automatically resets back to zero. Can it be if you didn't adjust anything the value doesn't change?
It would also be cool to have an option to lay out every channel on the mixer? Not a biggie but a nice request for this. My old mixer days it's nice to see it all at once. Hitting the pads a couple times is easy enough. Sometimes it's cool to see a piano and a kick mix together visually.
