[linux-audio-dev] midi controls API, is it possible?

Hi all, I am working towards using a set of linux audio apps in a live context. With recent development of Jack and apps such as djEQ and such, things look promising. In this light, an idea came to mind. (Keep in mind that I am thinking aloud, and that I am no expert in audio or midi programming). How feasible would it be to implement and a Midi controller API to have a standard, graphical ( a la qJackconnect) application API that Synths and such could use to change midi controllers assignment on the fly or load existing presets? I don't think that the audio framework that has been worked on in linux had live use in mind, but I am convinced that it lends itself to it. In the same context, and this might already be possible, is it possible to have a script calling different apps with patches/presets for each one of those? I am thinking along those lines: during performance: Call script -> opens say Zynaddsubfx with a certain master, Freqtweak with a certain session, Hydrogen with a certain song etc -> call end of piece from script which exits all these apps -> call another script for next piece.
