Check out Band in Hand! This is a way to start with what you have and go from there! It's pretty ingenious. Say you have only a guitar player. Well, this app can supply all of the other instruments! Say you get a bass player the next week.. simply remove the bass from the mix and now you are able to do guitar and bass live!
Check out the "how to" video and also visit the site for more info:
