Aside from using an exp pedal or turning the volumes to zero,is there a way of quickly toggling between normal panel volume and all sound off? Other KB's in the past had a local off switch.

you can put part local off in a user midi memory, or alternatively in panel memory with the expand midi filter ON, or easiest of all in favorites setting/others there is a mute keys switch you can put in favorites.

Thanks once again,Alec
