Thank you everyone for your feedback. I don't even remotely think it is easy to do this kind of job with even the best and most expensive equipment available. You have to know what you are doing, and be good, no, perfect at it.

So it's not always easy to get started in this business. I believe being in the background of a combo, responsible for rythm and some backing harmonies, would be a safe start. I will watch and learn and gain experience.

@Greg:
I'm not confident in my singing, so I wouldn't develop to an OMB either. I agree, the singing voice is very important, and a singer who's not "locked up" behind a keyboard can have much more contact to the audience. Show personality. Do you channel her voice through the keyboard for "vocal harmony" or things like that?

@Tony:
I think you can always "mark" the bar after one that is likely to be skipped in a midi, and if the situation arises, just jump to that mark. Doesn't work "on the fly", though.

As for using midi, I think it all depends on the situation. The size of the band, the music style, the audience, whether it's just "wallpaper" music, etc. But thanks for all your input.

@Scott:
That's the approach I plan to take, knocking out bass and guitar (since that's what they play) just filling in and maybe a little solo line once in a while. I like your input on psrtutorials, thank you very much for sharing.
