I built 6.0rc1 and had success with some simple MIDI tracks. Then installed avldrum LV2 plugin. In the mixer strip, for my MIDI track, I was able to choose the Black Pearl kit instrument from plugin manager.
Then when I double click to open the instrument UI, Ardour crashes.
My installation was simply to downloaded x42-avldrums-v0.4.1-x86_64.tar.gz (Linux 64 bit) from x42-plugins.com/x42/x42-avldrums
then copied the avldrums.lv2 folder to $HOME/.lv2/ ( /home/u/.lv2/avldrums.lv2/ )as instructed by the README.txt file.
It seems like this was successful when I installed for Ardour 5.12 some time back.
Can someone else offer insight on a successful avldrums.lv2 install in Ardour 6 RC1?
I thought this was a very popular ( and stable ) lv2 instrument, so maybe someone could give me a sanity check, and comment on their installation details… location, other configuration steps?
