LMMS • Forums

Starting LMMS from the terminal in Linux, I get the advice:

Lv2 plugin SUMMARY: 220 of 287  loaded in 5845 msecs.
For details about not loaded plugins, please set
  environment variable "LMMS_LV2_DEBUG" to nonempty.
Blocked Lv2 Plugins: 16 of 287 
  If you want to enable them (dangerous!), please set
  environment variable "LMMS_ENABLE_BLOCKED_PLUGINS" to nonempty.

However, when I set the variable using SET, and re-run the LMMS AppImage, nothing changes, and I get no additional info. Is there a log filed somewhere that I can read to find out which plugins were blocked or failed to scan?

Otherwise, I'd like to request that as a feature: (please store a list of blocked/failed LV2 plugins inside of a file inside of the LMMS prefs folder). For that matter, it'd be nice to get a list of blocked/failed LADSPA plugins also.

Any assistance on this topic is greatly appreciated.

Code: Select all

Blocked Lv2 Plugins: 16 of 287 
  If you want to enable them (dangerous!), please set
  environment variable "LMMS_ENABLE_BLOCKED_PLUGINS" to nonempty.

If we should investigate this, we need to know the version of LMMS. Including the +.... string
