Can you turn the Vocalizer harmony ON & OFF manually on the display somewhere?.....also can you use a SINGLE pedal switch to turn VH on/off? or do you have to use the ketron 6 pedal.....
or can you use a single "MIDI" pedal?

>>>AJ:- Yes you can. Press and hold down MICRO/VOCALIZER. Now on the left of the screen, you can turn ON/OFF the harmonizer. The fastest way is to use the VOCAL slider up and down to quickly access or adjust the harmony’s volume. You can program this and use one of the switches on the optional KETRON FS6/13 Effects Footswitch.
