What would you want besides Midi and Audio?
I think we should stop going round in circles about what it's called -- we can start out with Midi and Audio -- and just get those features onto the TCP by default already
If we start out with "Audio" and "Midi" that would be good enough, or "Universal" and "Midi".
I don't care how they implement it; they could weld a ReaMidiControl in thre and just change the presentation.
It's the exposition of the features that I think we all want not worrying about how they do it internally.
But yes I think people should be able to change the track type at will and not have it be a "fixed" type. It really just controls UI presentation.
I wouldn't say that a "Midi" track just gets "partial" -- a Midi track with an embedded VSTi would still have an audio path, it's just that the Pan/Volume would send Midi by default and rechannelize the data to an "output" channel.
And it would expose more features -- not less -- than a normal track such as Patch Name, etc.
