Apparently, what I look for is called Automaping and is available for
Novation gear, by means of some kind of VST wrapper. I doubt it'll work with 3rd party gear.
There are couple of freeware hosts and wrappers, too. I doubt those work at
all, in automaping sense, but will try.

However, above's not elegant enough.

Are more expensive units capable of what I look for, I select channel,
or plug-in, and available parameters come under controll of my hardware, without wrappers and stuff.
Anyway, sofisticated hardware is not real solution. Solution has to
be within DAW. DAW must provide functionality.

I found out Reaper is addressing the issue. Seams it's implemented by
manualy writing codes and comands. Well, nothing wrong with that, audio
engineering of 21st Century. In the past studio people used to solder and
connect cables, now they write commands and codes.
If I could only dig Reaper's user interface. Being, partly, from the old school, I prefer virtual studio looks and ergonomy. Anyway, I have Reaper installed, so will give it a try, once.
