Hi, I'm adding this in the hope that it will help someone else. Having found that I was only getting right audio when auditioning loops in Logics loop browser, I went on a hunt through the environment. I compared this to another project where the auditioning worked fine, and found that it had an audio Channel Strip assigned to audio channel 256. So I created a new audio track in the faulty project, went to the environment, and reassigned it to audio channel 256 (Channel: in the left hand inspector bar), renamed it to prelisten, and that fixed it. I now have stereo Auditioning in the Loop Browser. All the best Darren

Thanks for sharing Darren :) Yes. In Logic 8, Channel 256 is the prelisten channel (when auditioning in the loop browser) and when previewing in the Sample Editor. Cheers Rounik
