You need to enable a midi input in the Reaper preferences first.

QJackCtl shows the Arturia as an ALSA device, not a JACK device (see the "ALSA" logo on the device in QJackCtl).

Try either the JACK route:

1. Ensure Reaper is set up to use JACK MIDI (under Audio/Device I think?). I think it is set to use JACK MIDI in your screenshot.
2. Then Enable one of the Reaper MIDI devices, e.g. MIDI Input 1. (Currently it shows Disabled in your screenshot)
3. After enabling it, it should pop up as a JACK MIDI port in QJackCtl.
4. Bridge your Arturia from ALSA to JACK, e.g. with "a2jmidid -ue"
5. The Arturia should appear as a JACK MIDI port in QJackCtl. Connect this to the Reaper MIDI Input 1 port.

Or, try ALSA directly (haven't verified this, working from assumptions/memory):

1. Ensure Reaper is set up to use ALSA MIDI (under Audio/Device?)
2. Now you should be able to connect it directly to the Arturia ALSA MIDI port. (If my assumptions are correct).

Thank you noedig you helpful one. Qjack doesn't automatically do a2j which was my problem.
