I have performed for many years..using Midi set ups..2 ,3 and 4 keyboards...using Anatek Pocket pedals , daisy chained, or MX8 Midi control routing boxes....Never had a major problem and set up time never exceeded 10-15 minutes..

If you make sure you hook things up right at home..you won't get the hung notes or midi loops etc...on the gig..

I always experimented with my keyboards (mostly Roland)..midi back into themselves, and turn local off..Many times giving advantages the keyboard could not on it's own...In fact there use to be hidden system files to turn on that were never public...I recall the D70 was great in this aspect..
