Emu XL-7 & MP-7 User's Group

HELLO
I have a big problem when i'm playing with a friend : the both gear are
well synced (i have an XL7 in master and my friend an mpc2000xl in slave) ,
all is working fine but when his gear stop (he 's samlping something for
example) i have to press the stop button and then play to restart his
machine... it's a big problem because there's a big break !!!
so, if you have any idea to restart his gear without stopped mine...
