Incorporating samples into live shows FOR BACKING...

The other thread reminded me of the pickle I'm in.

Eventually I want to have a click in my ear and "samples" being played FOH. When we do our album there are going to be some strings, keys, and aux percussion.

so, wtf to do?

Ive been kicking around the idea of an mp3 player and a 2 channel mixer.

What type of setup would some of you recommend?
