Yes Eddie I do know a computer guy!
And yeah I have a pad, not an iPad but a Samsung, and I also have a droid phone and an iPod.
I can play MP3s from anyway of them, I even have an HP laptop.

I can easily enough mix down my songs in Sonar and leave out the vocal track.
I've seen some guys with the pad on a music stand, a laptop beside his mixing board and 1 who had his iPod affixed to his microphone stand.

It would be nice if I could trigger it with a foot switch.

As far as interaction, it depends on the club.
For instance Saturday at the Eastland and I was telling jokes about a quarter of the time.

I think there's 1 called guinness time.
And Val I'm so sorry, I've just been insanely busy getting my new CD ready for spring.
I do have the tracks and lyrics!
