control live playback via MIDI

Hi everybody!

I would like to be able to send commands via MIDI keyb that will allow me to interact while a score is playing. Eg:
- Change the volume and playback speed (entries in the "Playback Controls"
- Turn on / off the metronome
- Mutate and reactivate some tracks
- Change the volume of individual tracks

[I'm studying cello and I have written some of my exercises with student-teacher structure. Features I'm asking for will help me pretty much during my practice sessions]

Think about your actions by the master are possible?
Thank you very much!
Enjoy the Music!

very similar to this one, but... i didn't understand very much and I really don't know nothing about osc]
