I cannot reproduce the qmidiarp lv2 plugins not working in qtractor with transport.
As to other lv2 hosts:
They do work with jalv.qt5, jalv.gtk and Ardour 5 here, including transport.
As to Ardour, you are probably aware that ardour disapproves non-statically linked (self-contained) plugin GUIs (there is lots of discussion on that topic out there), and unfortunately qmidiarp falls into that category.
I had checked with Carla (2.0) once and it worked, too, but I cannot tell what the current status is.
So there's at least two different issues in your case, one with qtractor and transport and probably others with the suil library and I don't know about carla.
For the transport issue, you may check whether this works when qmidiarp is in standalone mode (qmidiarp app) with the jack transport button checked ?
In order to verify if https://github.com/emuse/qmidiarp/issues/7 is actually a qtractor or a qmidiarp problem, I tried to insert the sequencer plugin into an Ardour 6.6 MIDI track, but in that case, Ardour just craches completely. I also can't open the plugin in Carla -- when trying to open its GUI, I get a crash notification saying that "carla-bridge-lv2-qt5 closed unexpectedly".
Cheers --
