Hmmmm.. The 1010LT has MIDI in and out jacks.  Currently not used since
the Korg is connected using USB.  In Qjackctl's MIDI pane I see Ardour's
various MIDI connections, MMC, MTC, although in Qjackctl's MIDI pane,
Ardour is by itself.  There's nothing else to connect to.  

In Qjackctl's ALSA pane there is a 1010LT MIDI out as well as as Korg
MIDI in.  Connecting these two does not bring over any sync.  

What is this 'jack midi' you have mentioned ? 

Is it possible at all to have the MIDI clock signal carried over to the
Korg while only using the USB connector to the Korg ?
