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

Hello` Nice Group! 

I am mixing my patterns like records by using the xmix function.  Is 
there a way to exit xmix mode with out stopping playback of current 
pattern?

How do i assign tracks 1-8 to outputs 3 and 4 ??

I want to control my Korg MS-2000r synth with the PX-7,  but i can 
only seem to get my midi data(from keyboard controller) to transmit 
through on anything but track 1.   If I program a sequence on track 
9, how do i make the emu send the sequence data out to the MS2000R.  
Is there a way for the emu to store preset data from the ms2000r? 

Please help the newbie  : )
