The KN5000 has a function that copies measures from the sequencer to the composer that results in a composer style. It is not something that is easily done. But, it is possible if you have the desire to really study the keyboard. Unless the rhythm patterns in the Technote disks are really exceptional, you would probably be better off just to find an acceptable composer pattern already available for the composer(Gunnar Jonny has hundreds). I am not certain that this function is available on your PR702 but I expect that it probably is.
