EXS 24 Logic Sampler Users Group

Hi all, here's a question;

Ever since L7, when using the "load multiple samples" function of EXS24 II to make a 
sampler instrument, the samples play back at what sounds like the wrong sample rate 
when auditioning from the file selector using the play button - they sound about half 
speed, very clicky and glitchy, and only on the left channel.

We're on a 2GHz G5 with 2.5Gb RAM, OS 10.3.5, L7 Pro. We monitor Logic's output on the 
SPDIF digital outs from our MOTU 828mkII (labelled as outputs 11-12 in Logic), via our 
Sony R500 DAT machine. The 828 is digital master, clocking at 44.1kHz. We have a 
Behringer ADA8000 providing an additional 8 inputs to the 828 via ADAT lightpipe on a 2 
cable handshake connection. 

Could there be some kind of digital loop happening? Where is the audio routed when using 
this file selector - anyone shed any light?
