Two questions Fran...
Does the Go Keys have an arranger engine? i.e., does it recognize chords and transpose a style-based accompaniment in real time?? NOT looking to trade, just curious.

Also: the PA1000 and some other Korgs have a Chord Sequencer (originally a Roland feature.) The only recent Roland to have a C.S. was the now-discontinued BK-9. Aren't you a little curious about what the chord sequencer would add to your gigs?
