uneven & odd number beats

[Rei]

I'd like to know how it is possible to record or play uneven odd beat numbers with the KP3 like 7/8 or 4/5 - Is it even possible or is it not due to the solely DJing approach of the device? Would be very sad and astonishing since I play a lot with irregular beat-measures and I think it's opening a new dimension so to speak and would be very limiting if not possible, however I could not find out how to change the counting of beats in the KP3 and would like to know how to do that..
So please if any one knows, I'm eager to learn how to change 4/4 to any other, specifically odd numbered beats!
