You sure know how to start with a tough question
I would have a lot to say on the subject but you need to give us more info.
You say you've done some recording. What type? Midi orchestration? Recording yourself with a Guitar or band or looping?
Also, what software do you use. I know you mentioned Alberton but what about professional sequencers such as Logic or Cubase?
You said scoring and commercial work. Do you mean doing TV commercial spots or do you mean motion picture work.
What is your goal?
Are you well versed in computer technology AND music theory?
Shoot me back some more info, ok?
