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

I've been unsuccessful syncing xl7 to cubase. It starts and stops 
just fine the
first time around.  But if I hit play on Cubase again a few of xl7's 
MIDI tracks
get muffled while other tracks are normal.  So then I go into those 
tracks and 
switch to another preset then switch it back to the original preset 
(as if I had 'shake it'and tell it to wake up) and it would play 
okay.  I would have
to do this everytime as a workaround but it gets to be a hassle.  I 
am slaving my
XL7 to Cubase. Has anyone else seen this before?  I am very new to 
Cubase so I'm 
pretty sure it's a user issue.  Here is my setup:

MidiSport 2x2
XL7- do not transmit Midi clock

Cubase
Sync Source-
Timecode Base: Intern
Tempo Base:  Intern

Sync Out-
MIDI Timecode: On (Out-A USB MidiSport 2x2)
MIDI Clock:  On (Out-A USB MidiSport 2x2)


Thanx
Peace in da Middle East!
