EXS 24 Logic Sampler Users Group

Am I the only one who experiences this: When I edit a drum kit (say if I'm
compiled a kit from downloaded samples from the internet), when I trim a
sample, it no longer triggers unless I open another instrument and then
change it back again. To make matters worse, if I have the same kit on
multiple instrument tracks (instances), I have to change everyone of them
before changing them back to hear the sample trigger (or close and reopen
Logic). Since I do A LOT of sound editing as I compose, this leaves me
seething with frustration. Any similar experiences?
