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

hi , iv had a problem with my xl-7 a delay  problem with the notes? 

as soon as i unmute any extra tracks more than 1 , i can clearly hear a delay on the first 
beat or tick clocks etc, "to my trained ear"

its easy to hear this while playing tight drum tracks or notes with a midi clocked echo or 
delay as they become sloppy / messy to the ear once a second track is unmuted or more.

 please reply to me as this sucks & makes the instrument use less.

Iv run the tests for the unit & its Passes all tested ok .

The rom is v2 latest ? please advise?

Iv tryied the midi data thining on the song menus to excluded data from patterns etc . 
No joy !-(

Tracks playing are quantised to 16 note and play fine on there own right . or one at a time.

anyway the tracks im playing are very simple and should play fine . " no CC data "

1 note arp's start to sound messy after a loop to start of pattern "delays are bumped" ,
once any more than one track is playing "same delay at start of track problem" 

is this a common problem with the XL-7 software revision i have??

whats happing dudes?
