re. lilv_world_add_plugin() complains about duplicate plugins in /usr/lib and /usr/lib64 since it scans both...
yep that's true and that might just be nailing it; what happens when you set the environment variable LV2_PATH explicitly, like eg.:
LV2_PATH=~/.lv2:/usr/local/lib/lv2:/usr/lib/lv2
before qtractor is run. that way it will override the internal default to inlcude the lib64 sub-paths to the LV2 plugin search path on x86_64 builds, that is built-in when LV2_PATH variable is not set or is found empty at run-time.
