I would love to have more instruments available in the mixer for each song. Depending upon the style, we currently have a few options for the chording instrument. It would be great to have guitar as an option on every song. I would really love to see piano-electric piano-Hammond B3-electric guitar-nylon guitar-vibraphone for every song if that was possible, but at least having guitar as an option all the time would be nice.

Thanks for a great app! It is really the only reason I purchased an iPad.
