Okay, after plugging the Radias into a different USB port on my PC,
and after reopening the JACK Patchbay, I do see some connectors for my
Radias.  In both the "Input Sockets / Plugs" and in the "Output
Sockets / Plugs", I see a "RADIAS" entry.  And under the RADIAS entry
in each of those two lists are two entries: "RADIAS MIDI 1" and

I was thinking to try connecting one or both of the RADIAS-related
Input sockets to a virtual synth, so prove to myself that the Radias
keyboard's MIDI events can be routed to a JACK program.  But when I
launched various soft synths that came with Ubuntu Studio: QSynth and
ZynAddSubFX, they never showed up in the JACK MIDI Patchbay, so it
wasn't clear how to connect my Radia's keyboard events to any
softsynth (or sequencer, for that matter.)

Any suggestions for how I can demonstrate that the Radias keyboard can
drive some piece of software in Ubuntu Studio?

Much appreciated,
