A Few Technical Questions Concerning Every Host

[Sepheritoh]

But GPO is not a host, is it? And I was asking about hosts so that i can make my VSTi better. So I am still a little confused because in ORION you can automate any VSTi without MIDI cc's as it has its own internal system. I imagine that would include GPO, as it certainly works on everything I've tried it with.

No GPO is the VST and Sonar is the host. Sonar can do the CC automation and it is usefull in SONAR, because GPO can not automate these things in itself. I can not find any place in GPO to switch to VST / DX automation. Arming for automation only opens up the MIDI automation. A possibility could be to re-map NRPN messages (that is how Sonar use VST automation) to CC messages, but I have not tried that.
