I suppose the limitations Tristan mentions about the AU plugin format relate to the fact that the AU format is Mac based. AU seems to be Mac and VST more Windows, although they have more in common than differences. Plus, VST can often be used on Mac.
I’m not a Kontakt user, but from what I’ve seen, it always runs through a front-end controller and not as individual plugins. So I’m guessing this Kontakt front-end controls the midi configuration too. Davide seems to use it a lot.
Davide did say that the midi could not be configured at this moment.
I did leave a post about how the Multi-Out options did seem to improve the sound of the AU instruments. I would like to hear all comments and suggestions on why this should be. Here is a link…
