I had to discover that there are problems with VST3 plugins and Program Change. I have a virtual instrument requiring Program Change messages to change sound/technique, and it doesn’t work when hosted in VEPRO as a VST3 plugin.
The same virtual instrument works fine in Logic, with VEPRO as an AU plugin.
Is there any hope this compatibility issue between VST3 and Program Change to be resolved? I see this was already reported years ago, but I also see it is still there.
As an alternative, do you think there is a way to use VEPRO as a VST2 plugin, instead of VST3, in Dorico? Since I don’t use VST3 for anything else than Dorico, maybe I can just remove the VST3 version of VEPRO?
