Hi guys,
finally I am posting here my Setup I use during our worship meetings. It is the same I use in my Kurzweil PC4 Video Contest: https://www.youtube.com/watch?v=lt_VsoVvJzo

One notice to the "hold" switch (see attached controller settings): It is MIDI CC Sostenuto, so when you want it to work as drone for eg. SynthPad:
1/ press desired notes
2/ press the "hold" switch
3/ mute the zone (be avare that in this case the zone does not respond to controller changes unless it is unmuted)

I hope you will enjoy it.
God bless
