Once again, the hold button makes this songs bridge possible. The XWP1's saw & AH synth tones  are being held by the sustain pedal. The lead tone is being held by the hold switch. The sound FX's tones are being held by the hold switch.  The XW's saw synth & PWM tones sustain pedal is being passed through Mainstage2, unfiltered.  The FX's tones sustain pedal "CC#64" is being disable through Mainstage2,  thus not respondent to the closure of the pedal, as well as the lead synth tone.
Take my word… The songs bridge "Played Live" isn't possible without the hold button. It would require  exhaustive editing of each tone to do this without the HOLD button.
