Scanning for Plugins

Zrythm will scan for plugins on startup and will remember those plugins until it is closed. Zrythm supports both LV2 and VST plugins, although LV2 is the recommended standard.

Tips

Plugin scanning can be disableld by passing NO_SCAN_PLUGINS=1 when running Zrythm.

LV2 Scan

Zrythm will scan for LV2 plugins in the standard paths specified here. You can bypass this behavior by passing the LV2_PATH environment variable to specify custom paths. For example, LV2_PATH=~/custom-lv2-dir zrythm.

VST Scan

On UNIX, Zrythm will scan for VST plugins in the following paths.

  • ~/.vst
  • ~/vst
  • /usr/local/lib/vst
  • /usr/lib/vst

You can bypass this behavior by passing the VST_PATH environment variable to specify custom paths. For example, VST_PATH=~/custom-vst-dir zrythm.

Obs

lib will be replaced with lib64 depending on your system.

On Windows, Zrythm will scan for plugins in the paths specified in VST plug-in locations on Windows.

  • C:\Program Files\VSTPlugins
  • C:\Program Files\Steinberg\VSTPlugins
  • C:\Program Files\Common Files\VST2
  • C:\Program Files\Common Files\Steinberg\VST2

Since scanning VST plugins takes a long time, Zrythm will remember scanned VST plugins and save this information in <<ZRYTHM PATH>>/cached_vst_descriptors.yaml. New plugins will be scanned on each start-up, and you can delete or edit this file to force a re-scan of previously scanned plugins.
