Here's a set-up to play Swingtown. From Low "A" to "G3" is a Strat/Clavinet type sound to simulate the clean guitar part. From "E5" to "E6" is a sound for the main synth line. "G5" to "D7" is a synth brass sound that sounds great for the 3 part instrumental part on the end section of the song. Play the synth melody with your left hand, add the 2 part harmonies with your right. Oh, and from "F#7" to "C8" is the jet sound from the very end of the song. Have fun.
