I have a TTM57SL and use the browse menu a lot. The function of the 57 to scroll through crates and tracks will not work while browse is selected. I must use the keyboard at all times while playing out. I bought the 57 to keep my hands free from the computer and more onto the mixer. Is there anyway to impliment the P1/P2 knobs or joysticks to allow scrolling inside the browse menu please? Any ideas from others or suggestions to make this function work?
