EXS 24 Logic Sampler Users Group

Hello all,

I'm running Logic Gold 5.5 on OS 10.2.5 and everytime a play back a 
midi sequence through EXS24 and change the patch/sound as it's 
playing it crashes Logic totally.

I'm running it on a Dual 1.25, with 512MB Ram any ideas as to why 
this is happening?? If I change the sound while not in playback mode 
all is fine.

Kind regards,

Steve
