Bill, you could set an entire bank of mic effects if you wished, that would provide you with up to eight vocal effects and harmony types to select from anytime you wish. However, in order to do this, it would mean going back through all your registrations and removing the mic settings, then resaving them. This would allow you to not worry with the Parameter Lock and leave it unchecked all the time. Of course, you would still have to select one of the 8 registrations right after firing up the keyboard in order to recall the vocal and pedal settings.

Donny, I've been doing this for so long that it's an automatic thing, same as turning on the keyboard or amp - no big deal. And, the selection of effects is almost endless. You can set it any way you wish, from nearly flat to tons of reverb - it's up to you, then once saved, it's instantly recalled with the touch of a single button, no different that selecting any other feature or registration.

All the best,

Gary
