My first though about it is the dismay in learning that the CS is an audio function. This is absolute lunacy! The entire REASON for a Chord Sequencer is that it records ONLY the chords, and you still have complete control over what the arranger does with those chords as if you were playing them yourself.

An audio recorder is going to record everything you do, fills, Variations, stops, you name it. Barely worth the time of day. Might as well make an SMF of the backing, and use that!

Roland, call me! Your boys have lost their minds!
