Hello! Tim from the MusE sequencer project here.
I am reaching out for help on some bizarre issues. I am trying to figure out where the problem lies.
Normally I'm very tenacious but I'm spending way too much time with individual plugins ;-) Help!
AVLD's ui opens, but does not seem to respond to left-clicks at all.
Right-click works (Text vs. Tips etc.) and mouse wheel volume works.
There is no animation at all of the drum 'hits' in MusE.
Yet in QTractor it works fine.
On my machine it will not even play the notes we send to it from our pianoroll editor,
drum editor, or piano keyboard or drum list.
But another user says that last bit does work for him but he also does not get the animations !
I verified that lilv_instance_activate() is called, and that lilv_instance_deactivate() is not, too soon.
Is it my understanding that we should be receiving something on the plugin's midi out port?
I get absolutely nothing.
I verified lilv_instance_connect_port() is called on the output port.
I examined the actual memory buffer that we connect the midi out port to.
Seems absolutely nothing being sent to us on that midi out port.
And on receiving such an event, are we to send it to the UI or something?
Could that be why the animations aren't triggered?
(I know that for example, with DSSI we had to send them back to the UI,
but with DSSI-VST it was a very different, very complicated ballgame since the
plugin did that by itself.)
The other user that I mentioned said this, maybe it means something:
It may be a very remote chance that your version of mesa or libinput may have an issue
if you're building it with the latest qt 5.12 on an Ubuntu LTS, I had a similar issue
a while back in Ubuntu 16.04 after compiling Qtractor and not being able to get sound
out of certain plugins when using qt 5.9.
Appreciate any help.
Thanks.
