My thought, although not completed yet.

1-I purchased a Boss drum machine with all kinds of rhythms. Sad to say for me they are mostly comtempory -- Maybe an older drum unit would be better for me.
2-It does not have to be a drum machine, it could be another keyboard -- but, it must have midi out.
3-I matched ths midi chanels to the keyboard chanels so they able to speak to each other.
4-Played the drum unit -- recorded with my KN7000 into the sequencer --- then into my pads or composer.

No perfection yet, just trying to work it out.
