Indeed, "most plugins" seem to get this in information as to what track
they are in (Calf MonoSynth, randomly) so how do I implement that in "my
plugin"? :)

It would be really useful to be able to find out from the host what channel each instance is on, both for presentation in UI and for support of automation-type behavior where the plugin might automate usage of (for example) a hosts OSC API, using its channel number to parameterize the OSC call properly. This is what I think of as the "max4live" workflow.

How can I have my cake and eat it?
