Hello Andrew,

Composer does not directly support VST plug-ins. I don't know whether this means that there isn't a way that Kontakt2 can appear to be a MIDI device to Composer. GPO Studio makes the Kontakt player appear to be a MIDI device to Composer, but that is because GPO Studio is itself a VST host for the Kontakt Player, which is a VST plug-in.

I suspect that either Native Instruments offers a VST host that makes the Kontakt2 player accessible as a MIDI device, or some third party offers such a tool.

To you feel up to researching this? If not, I can Google around or ask Native Instruments.

Cheers
