Can you work the whole MIDI thing with your drum machine? If so, you can enter info in a MIDI track, and if you have the MIDI interface hooked-up, the drum machine will play the notes you entered in your Cakewalk MIDI track (entered in the piano-roll view or the staff view). To record, just arm an audio track for recording, and when the MIDI track is playing through your drum machine, the audio track will record it. Hope this was what you were looking for.
