GCumbee is correct. When using the DAW Control driver on OS X to emulate HUI or Mackie Control, the DAW Bank up/down function on Softkeys allows the MIDI strips to control multiple banks of DAW tracks. For example:
– 16 MIDI strips on Qu-16 can control DAW trk 1-16 but also switch to DAW trk 17-32, 33-48 etc.
– 8 MIDI strips on Qu-24 (say you want the other custom strips to control DCAs, inputs and mixes) can control DAW trk 1-8 but also switch to DAW trk 9-16, 17-24 etc.
