Here's a Setup I did for playing Purple Rain live.
It's a 7 zone Setup split at D#4
Zone 1 is a modified preset for the Piano for chords
Zone 2+3 is the layered Strings for the left hand
Zone 4+5 is more aggressive strings that can be added to the left hand by pressing the footswitch
Zone 6+7 is again Strings , but they only play on the C2 note and can be left sustaining by pressing the SW switch, this allows you continue playing with both hands while sustaining the note, this is for from the Guitar solo till the end of the song, pressing SW switch stops the sustain.
