Hi Mark, I tried what you told me but Composer does not recognize Kontakt 2 there is Midi Information being transmitted but no audio and before opening Composer I have kontakt 2 set up and producing sound and really very nice sounds indeed!!!But Composer does not seem to want to work with kontakt 2 yet!.Can I re-download Composer Pro trial version and try it out with kontakt 2 and see if it is any difference. Thanks, andrew
