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.
