I have a problem where I load my sample into the EXS24, I cycle a 
section of any song practing the part, and then the sample audio 
drops out after a few minutes.  The EXS shows that the sample is 
loaded, but no audio.  If I try and reload that sample or any other 
sample, still no audio on the track.  I am however, still able to 
trigger my EVB3 or EVP88.  I have to exit Logic, then upon rebooting 
it, it ALWAYS will crash a couple times, then I'm able to enter the 
program and reload the sample, in which case, it will dump the sample 
again.

I don't know if it has anything to do with the size of the sample.  
It's been happening while I'm tracking the Bardstown Audio Piano 
sample (it's huge).
