EXS 24 Logic Sampler Users Group

Anyone have any suggestions for improving EXS performance (or modifying 
it's voice stealing method) when dealing with voice hungry instruments like 
the Bosendorfer Imperial Grand?  I seem to be getting a lot of voice dropping 
on the Bosendorfer when using the pedal heavily, those 64 voices go fast it 
seems.  I've read some of the past posts on creative note stretching in the 
matrix after the fact, but  that seems like a time consuming work around.  I love 
the Bosendorfer, & EXS, but it seems it's voice stealing could perhaps be 
better so the drop outs are not so noticable in pedal heavy playing.  Any 
suggestions would be appreciated.
