Since VST3 SDK 3.7.5 (IPluginCompatibility interface) it should be possible to auto migrate Kontakt 6 to Kontakt 7.
If Kontakt 6 gets disabled or removed from the vst3 plugin folder and Kontakt 7 is present your VEP project or meta frame will load with Kontakt 7 instead.
The benefit?
No one has to manually replace Kontakt 6 with Kontakt 7.
Because manually would mean:
- one has to save each multi in each Kontakt 6 instance manually
- replace each Kontakt 6 instance with Kontakt 7
- reload all multis in each Kontakt 7 instance
auto migration would do all that automatically without the need to save multis at all!!!
