I’m trying out Ardour 3. No trouble compiling, but I notice that Ardour’s MIDI control now shows up in the MIDI tab of qjackctl instead of ALSA, where it shows up in the version 2 series.
This is a deal-breaker for me. I use Openoctave, which shows up under ALSA.
How do I now connect the sync out of OO to the control in of Ardour?
I do not know if I correctly understood your question, but I think it is related to the difference between the ALSA MIDI used by OpenOctave and the Jack MIDI used by Ardour 3.
