EDP Problem: Delay in Mute mode

["ARTHUR LEE MUSIC" <arthurlee@arthurleemusic.com>]

I'm having a weird thing happen..

When I press Mute there is a short delay in it's activation and "ooo" comes
up on the screen.
It does it sometimes and then doesn't do it at other times. Any ideas????

I have both FCB1010 Midi foot controller and the analog FC7 hooked up to my
one EDP...
I am assuming there is no problem with that switching scenario.

I like throwing myself fast learning curve balls!
