My dad plays rhythm guitar. He is looking for a module that will allow him to have accompaniment as he plays. He doesn't want a pedal board, he wants something that will track with the chords he plays on the guitar. Does such a thing exist? Something with good styles. He does mostly country music.

I'm guessing he'd need something that would convert the notes of his guitar to midi. Then hook that into some kind of arranger module. And then this arranger would need to understand guitar chord voicings so that it doesn't play the wrong bass notes or whatever, because guitar voicings tend to have different notes on the bottom, and the arranger would need to not be confused by muted strings. I'm sure you all get my drift by now. How would we go about this?
