I use Ardour 5.2, Ubuntu 18.04. QT5 libs installed.
All samplv1, padthv1, synthv1, drumkv1 work just fine in Carla.
When I try to add any of them to Ardour MIDI track, I get some
[ERROR]: LV2: Failed to instantiate plugin http://padthv1.sourceforge.net/lv2
in log and alert like http://i.imgur.com/UkM0YTg.png
I found some topic in internet and changed some lines in ttl file or something like this. Seems it “helps” and I can add drumkv1 but when dbl-click on it I have
[ERROR]: failed to instantiate LV2 GUI
At the same time I saw Unfa youtube video he uses samplv1 without problems (https://www.youtube.com/watch?v=FTqEdPavUmQ). What should I do to have the same?
