EXS 24 Logic Sampler Users Group

Ned,

Even more disturbing (and in addition to my "exs crashes..." thread) is that this occurs 
under even less strain.

My test involved a six note chord performed on three EXS instruments with many 
combinations of the factory installed EXS samples. These should not by any means tax 
the virtual memory system as they are all very small samples. These still crashed my 
system at a usage of merely 18 voices of total polyphony.

I also tried this with an external Firewire drive, and the same problem occurs.

I am sure that this problem occurs well below yourr 150 voice limit, nevermind 1000. 
If you tried scaling down your test, you will most likely see the same results. Keep an 
eye on your "could not get data in time" counter in the virtual memory settings panel 
and you'll see it immediately start to rise.

There is something severely wrong here and I hope we can find a solution very soon.
