Delaying MUTE action?

["Gerry P" <manda@nomin.norlink.net>]

I had my EDP set up so that when I hit MUTE, the loop would continue 
playing
until the end of the current cycle and then mute - and hitting UNDO, 
started
the loop from the start - immediately.

Last night I was playing with some EDP settings and now I can't get back to
the above.  Not only that, but the manual says that MUTE always acts
immediately???

Any suggestions would be appreciated.
