I ditched the Multi template for Logic. Couldn't get it working right. Plus I did a bit of research and it works better with Logic and VEPro to use single instruments in Logic, and then connect these to single VEP instances. So you use more instances, but you get better performance. I did find that in Logic I could create a Multi out instruments. Then in the Arrangement area if I clicked to add another track underneath it, it would add a MIDI instrument with the next MIDI channel. All I needed to do was then change some of the Outputs for the tracks in Logic, and in Kontakt in VEPro. I found this in the Groove3 tutorial. It works pretty well.

The only downside is that you can freeze a multi-instrument like this in Logic. But that's really the only downside.
So that's one way around it. Or else use single instruments in Logic linked to single instances in VEPro, and if you do wanna do some articulation switching you can use SkiSwitcher. I found this works pretty well. So I only ned to have one instrument and use SkiSwitcher to do all the articulation switching for me.
Hope this helps. VEPro can be quite a setup hound. But once you get over the hurdles with it and Logic it works pretty well.
FYI, I've currently moved over to Cubase, because of its better handling with multitimbral instruments and VEP.
