I can’t remember when it last worked,
but now when I try to connect a virtual MIDI keyboard (to play MIDI notes with my laptops’ keyboard like jack-keyboard & VMPK), neither shows up in Ardour.
What I’m trying to do is connect the virtual keyboard to a synthesizer on a MIDI track in Ardour.
I’m running Ardour version 6.9.0 on 64 bit Intel, Fedora Linux. I installed the Fedora Jam ‘spin’ which comes with audio software preinstalled.
If I’m not mistaking I have ‘pipewire-jack-audio-connection-kit’ installed. I don’t know to what degree that could cause issues.
It’s kind of weird, as it has worked before.
I’m sorry that I don’t have so much information to give though.
Regards & thank you in advance,
While I cannot help with the direct issue, Ardour 6 has a built-in virtual keyboard (Ardour Menu > Window > Virtual Keyboard).
Other than that, check that Ardour is using Audio System: JACK (in Ardour Menu > Window > Audio/MIDI Setup), and that other applications are also using Pipewire’s jack emulation.
Perhaps try to make it explicit:
pw-jack jack-application-to-run-here, and check if the JACK ports are listed:
pw-jack jack_lsp. That may help to investigate the issue.
Thank you. The builtin virtual keyboard works.
And I’ve just tried it again, and now ‘jack-keyboard’ seems to work as well.
