[LAU] External arpeggiator and MIDI sync ?

[jonetsu at teksavvy.com]

Hello.

  I would like to sync the arpeggiator from a Korg Microstation to
Ardour.  The user guide says: 

  "the arpeggiator will synchronize to the MIDI Clock and Start
   messages received from a connected MIDI device."

The audio card is a 1010LT.  The Microstation is connected through USB
and is fully seen in jack (qjackctl).  Is it possible to have MIDI sync
for the external synth ? How would the wiring be done ?  Will there be a
need for an Ardour MIDI track for the Start (and possibly Stop)
signals ?

Thanks.
