Re: OSC changes/updates

I definitely want the possibility to set automation states by OSC.

I recently submitted a PR on github, to set the gain automation state.

Paul then said it should be more generic like

/ardour/route/automation_state "gain" "w"

thus allowing for

/ardour/route/automation_state RID "solo" "m"
/ardour/route/automation_state RID "mute" "t"

I implemented this against 4.7 in my local installation, as I really need this 
feature.

I haven't submitted a new PR because I want to wait until things get settled 
after the vca2 merge.

BTW: I looked into the vca2 branch and admittedly I don't understand what it 
is about. Is there some "white-paper" or some archived discussion on it, so 
that I can get to know what is the actual goal of vca2?

Thanks, 

Johannes
