qtractor silently ignores Surge XT LV2 plugins

[yurivict]

When I am trying to ass the Surge XT plugin to the track - it isn't shown.

All installed plugins:

$ lv2ls

http://breakfastquay.com/rdf/lv2-rubberband#r3mono
http://breakfastquay.com/rdf/lv2-rubberband#r3stereo

http://lv2plug.in/plugins/eg-scope#Stereo

https://surge-synthesizer.github.io/lv2/surge-xt

Plugins shown by qtractor:

In case an LV2 plugin is rejected for some reason - qtractor should show it in gray and there should be an explanation for why is it rejected.

Carla can add Surge XT plugins without a problem.

where is surge-xt installed exactly?

lv2info https://surge-synthesizer.github.io/lv2/surge-xt | grep Bundle:

check the path is included in View/Options.../Plugins/Paths for LV2 and add it if not.

[yurivict]

LV2 plugin path in View/Options/... is /usr/local/lib/lv2.

This is the same path where all LV2 plugins are installed by default.

$ ls /usr/local/lib/lv2/Surge\ XT\ Effects.lv2/
dsp.ttl                libSurge XT Effects.so manifest.ttl           ui.ttl

that's not the Surge XT synth anyway

please press Shift+ or Ctrl+"Rescan" button on the plugin selection dialog or remove all entries in View/Options.../Plugins/Paths (for LV2)

if that doesn't work, then IDK sorry

[yurivict]

When I removed the entries from View/Options.../Plugins/Paths (for LV2), and all blacklist entries - Surge LV2 plugins became available.

Blacklist entries didn't contain Surge XT plugins.

[rncbc]

Blacklist entries didn't contain Surge XT plugins.

LV2 plugins are never blacklisted.
