Hi Mark, Kontakt 2 port is not listed in the MIDI device configuration window nor does it appear after using the Port/select ports command. I am able to record with Kontakt 2 and hear it while I'm recording into Composer and it records my note data just fine but I still do not hear playback from Kontakt 2. Kontakt 2 works just fine as a stand-alone player and as a VST plugin in Steinberg Cubasis.I know that it would be hard for you to trouble-shoot this problem without having Kontakt 2 on hand. Thanks, Andrew
