The external USB midi port shows up in the qjackctl graph. The midi dongle works fine in other Windows apps. It was also working with jack not long ago since then I have upgraded the PC and reinstalled Windows. Windows version is 10. qjackctl messages: 03:45:32.764 Statistics reset. 03:45:37.209 JACK is starting... 03:45:37.210 D:/msys64/ucrt64/bin/jackd.exe -S -X winmme -dportaudio 03:45:37.281 JACK was started with PID=11604. jackdmp 1.9.22 Copyright 2001-2005 Paul Davis and others.
