Don: Hmmm, my keyboards (Tyros/PSR2000) won't remember the mic settings once the keyboard is turned OFF, so . . .

as Fran Carango does, I include my custom mic settings in a 'default registration file' (and which includes all my keyboard's other preferred settings as well) which I always have to remember to load right after turning on my keyboard. For all other subsequently loaded registration files, I typically (as DonM suggests) leave the Reg Memory Content's 'mic settings' box UNCHECKED. - Scott
