FWIW, when I work with both H2 and Ardour, once I’m satisfied with the H2 “song”, I actually export it as MIDI file from H2 and import it in Ardour.
I find it simpler than going through the hassle of recording the MIDI.
After testing, I figured that it was the problem with hydrogen that it’s not outputting MIDI signal at all from the TX, it can only accept midi control from RX.
Thank you for the reply
Well, it does output MIDI ! and I can record it in Ardour if I want ! It’s just a bit of a pain to setup …
In H2, in the instrument panel, you have to make sure each used kit element has a channel number defined and the expected midi note.
MIDI channel is OFF by default, which most likely explains why you’re not receiving any data in Ardour
