There is a solution that I bench-tested today, that will enable VST3 FX & VI plugins to be hosted within VEPro7.
This solution will allow you to host multi-MIDI input & Multi-audio outputs, such as reqiuired when hosting multiple instruments in Kontackt 7 within VEPro7.
This solution also offers Delay Compensation and up to 16x oversampling.
You can save all parameters in the DAW session, as you would nornmally do.
All for $59.00 and great customer support too !!
Check it out with the demo (does not allow session saving in demo mode, but it works 100% for me in the full version)
