as per richarius; MIDI notes put out by your drum machine can be used to provide a gate which is rhythmic rather than a steady pulse.
most stand-alone converters will allow you to extract the MIDI clock itself, often with a divide-down feature that will give you several different rates to clock your sequencer with.

consider using one of the faster rates to clock a gate sequencer, then pull the individual stages off the gate sequencer to trigger your tkb.

we sometimes will use a compressed/limited drum signal to trigger a slew or DUSG directly....kind of a cheap n' nasty way to get a valid trigger - set the module up for its shortest rise/fall times and adjust the volume of your input audio till the module starts cycling. the end-of-cycle pulse provides a fairly reliable trigger for clocking sequencers.

consider using more than one technique simultaneously. try using a MIDI event to reset the TKB, but advance its clock from a conditioned audio source - now you'll have a clock which might occasionally double trigger or miss a trigger, but you've got an easy-to-get-at pulse you can use to reset the sequencer while your pattern is running.

hope this helps!
