Hi Andrews,

I'm afraid that this discussion has gone way past my area of knowledge about VST, let alone other software products that I don't have here: Kontakt2 and VSampler.

It may be that the only solution here is that Composer needs to add VST hosting support. This has already been recommended to me by others.

If there is a way (some sort of software adapter) to make Kontakt2's playback accessible via a MIDI application that doesn't act as a VST host, then maybe you can learn about that from other knowledgeable Kontakt2 users in another forum, hopefully Native Instrument's. You might not learn anything more in this forum :-(

It's on my to-do list to explore adding VST host support to Composer. I wish it were there now for you.

Cheers
