vegas pro is also an excellent daw for audio editing,but will vegas pro ever support midi (vsti)?
Though Vegas is a very good audio editor but because it doesn't support midi is why I use Cubase for midi control.
VST was developed by Steinberg (Cubase's parent company)

Imho it would be very long road for Vegas to implement half of what Cubase or other midi DAWs can do.
damian-c, in case you missed it, the Vegas product owner has been asking for your input on a thread in the News forum: https://www.vegascreativesoftware.info/us/forum/vegas-pro-14-update-4-build-211--104988/?page=3#ca651843
