F Kara,
After we got off the phone today I called my friend at Korg USA to varify a few things. In Backing sequencer mode you can first input all the form of your song by selecting the variations and fills and styles in real time (without ever having to record a note or chord) and then you can enter your chords in step time either by using the buttons for time values and the screen for the actual chord types or if you would rather just scroll to the spot in the measure you would like to enter a chord and just play the chord using the keyboard keys, you can enter the chord at anypoint and it will play until you scroll through and input another chord. This way is very fast rather than having to put a value for each beat of the measure within the song.
As I mentioned on the phone, you can't record melody tracks in step time at this time, but perhaps another operating system update might let you do this.
