I'm strongly waiting this also to be able to deport those heavy Acutstica great sounding but CPU killer plugins.
The insert trick will not work in Cubase due to de VSTi nature of the VEP plugin witch can't be inserted in an audio track. So bound to return to instument tracks :-(
Adding a VST (fx) dll, vst3 (fx) or AU (fx)... for VEP return would be the solution. With the capacity of returning any choosen (pair of) ouput track(s) of the selected instance (FX or Instrument why not?). This seems no so hard to implement, it's the reverse path of the VEP audio plugin.
Maybe we could have to choose between two kinds of instances, Intrument or FX but this not seems necessary with the idea above of the "universal" returning plugin witch would allow very flexible routing capabilities, even for instruments.
@Paul?
Also, speaking of Acustica, VEP7 is rejecting all my Acqua plugins at scan (vst2).
The only solution is encapsulating them into N4 witch is acceped by VEP.
