One last point, since you're coming from Cubase... All of the above is mostly talking about how to direct MIDI to the VEP plugin, up to 127 channels of it. But what about the audio?
The audio by default comes back as mixed stereo from VEP. Remember when I said above that Logic will put one and only one mixer channel on the mixer window for Inst8. That channel is where the audio will be coming back into your mixer from VEP.
If you use additional audio outs in VEP (up to 25 stereo), then you can hit the little "+" button on the side of the above mentioned mixer channel, and you will see additional AUX channels show up in the mixer which will be getting those additional outputs from VEP.
So basically you can have 127 midi channels feeding into one VEP instance...and you can have up to 25 stereo channels coming back. There is absolutely no built in correlation between the input tracks and midi channels....to the returning audio on those 25 stereo returns. You can keep it simple in stereo, mix it in VEP, route them from VEP over whatever outs you want...up to 25 stereo. But the point is there is absolutely nothing automatic that will route the first track to the audio outs 1/2, the second track to outs 3/4, etc.. You can setup that in VEP and with the above mentioned AUX's..but its not automatic.
