IIUC you aren't asking for sync in general, but you wish to record the
guitar and after a while Hydrogen should start?

So, I'm not an Ardour and Hydrogen user until now, but I'm experienced
using MIDI and non-MIDI sync.

As far as I understand your question, you only need to add 'empty'
patterns to the 'Hydrogen song'.

E.g. make a song with Hydrogen playing nothing for e.g. 10 bars and then
let Hydrogen play the needed patterns, sync should be done by JACK

I guess Hydrogen differs between 'pattern play' and 'song play'.
