I’m trying desperately to minimize the number of rackspaces to reduce load time and memory requirements, My most common keyboard instrument combination is a B-3X organ and either an acoustic piano, Rhodes, Wuli or Clavinet. I use my top MIDI controller for the B-3X and use drawbar widgets to set and save settings between variations. On the bottom keyboard, I want to switch between Acoustic, Rhodes, Wurli and Clavinet using variations within the same rackspace. So it would look something like this.
My question is, what is the best way to toggle on/off the instruments under the bottom (SL73/88) keyboard, such that I have a variation with just acoustic piano, another with just Rhodes, etc.? What widet(s) would I use to effectively enable and disable each instrument and can the widget settings be saved for each variation?
