I know the title sounds a bit weird, but what I am trying to do in my quest to learn how to play songs on my KN7000, is to record the chord sequence in step time (CHD Track) and the melody either in step time or real time depending how hard I find it. Then start the sequencer with the melody turned off so I can practise the melody part with the chord track playing. The problem is I can't do it the other way round i.e. have the melody play in the sequencer while I practise the chords and have the APC playing. If I turn off the CHD track and press Start the melody plays but the APC will not start so I can't practise the chord progression.

Any ideas how I can play the chords with the melody playing via the sequencer ?
