I currently run all my own sound in my shows. Even when I play larger venues that have a sound guy, I still use the Airclick Performer (from Mr2Guy) and run everything off of the computer.
(previously I used a showtech)

I would also like to add some video to my show, but still want to control everything with a remote in my pocket.

Can I do all of that in Keynote on my Apple, or is there another solution that I should look at?

I was thinking of attaching music tracks to blank slides in keynote, and then when I need video, I could have that as a build in a slide (still with music playing. I could attach the track to the video if I had to, or keep it separate if that would work).

Then, I could just fast forward through the slides....

Can anyone help me on this? Will this work?

I use my Showtech (still mini-cd) fpor this with its ability to send DMX to my lighting board.

Tim,

One of the links on my Remote Show Control website is to a listing of show control software.

This list is maintained by John Huntington, who wrote a book on show control. There's at least one Mac-based system on the list off the top of my head. I think you might also want to take a look at this system, just to get ideas:
