Qtractor doesn't show LV2 Qt4 GUI (qmidiarp)

Hi

I have noticed that the GUI is not available for the QMidiarp LV2 plugins. I'm guessing this is because they are still Qt4 while Qtractor is now Qt5. I have the Qt4 libs on my machine and
> jalv.qt4 https://git.code.sf.net/p/qmidiarp/seq
works and shows the GUI. Is there any way of configuring Qtractor to show the GUIs? Without the GUI the qmidiarp LV2s are pretty useless.

exactly.

you have to install the Qt5 build of the QmidiArp LV2 plugins for the GUI to show and run under Qtractor (Qt5 build);
or vice-versa, you need to install and run a Qt4 build of Qtractor to let Qt4 plugin GUIs to be any usable.

though, I'd recommend the former, as Qt4 is coming to a deprecating phased-out stage any day sooner or later.

hth.
cheers

I built qmidiarp from source with the --enable-qt5 option, and now the GUI appears and everything seems to work.
Cheers
