EXS 24 Logic Sampler Users Group

Thanks everyone for all the help,
For starters....I'm using OSX...sorry not to have mentioned that.  I'm 
up against the wall on memory for a laptop.  1gig is all I can have.  I 
have de-fragmented the hard disk and it was pretty badly fragmented, 
but I didn't get any noticeable improvement.  What is odd about this 
case is that freezing tracks seems to exacerbate the problem.  This has 
not been my experience in the past.  Freezing does alleviate strain on 
the "Audio" side of things....but I immediately get Disk i/o failures.  
1 frozen track will do this.  I am freezing at a lower bit level.  That 
eased the problem on a previous composition.   By the way, you set bit 
depth for freeze tracks in the Audio preferences window.  I've set the 
buffer values on my audio driver to maximum.  I thought that would give 
the best playback.   I reduced polyphony on several of the EXS 
instances...It helped in a couple of spots.

My samples and freeze files are on one external 80gig 7200 rpm hard 
drive that is partitioned into 2 sections. Maybe it's time for another? 
  I have actually been suspecting my audio card.  I recently tried to 
switch from the Digigram V2 to the 440 to get 2 additional outputs.  I 
couldn't use the 440 because servicing the additional outs caused a 
marked decrease in performance.  Sooo....I thought maybe another card 
might increase performance?  	Relieve strain on the CPU?   When I 
bought the digigram V2 it was just about the only "professional" option 
for laptop users.  That has changed.  Any ideas on that front....or am 
I on the wrong track there?

Thanks again
