[LAU] Ardour3/jackd: connecting MIDI in/outs ?

[jonetsu at teksavvy.com]

Hello,

   I'd like to have a rudimentary click track in Ardour3 (3.1.10) which 
would use the a sound from a Hydrogen kit.  There is now a MIDI trck in 
Arodur3 and in qjackctl I can see various Ardour3 MIDI ins/outs under 
the MIDI tab.  But the Hydrogen MIDI inputs are under the ALSA tab.  
Ardour3's MIDI connection matrix neither shows any Hydrogen instrument.  
How to connect the two ?

   It also seems possible to eventually have the click from Ardour3 sent 
to a Hydrogen instrument - is this possible ?
