Lv2 is supported on master.

Requirements

Arch Linux

pacman -S lilv lv2

MacOs (HomeBrew)

brew install lilv lv2

Ubuntu

For compiling: lv2-dev liblilv-dev

Windows

From the directory containing vcpkg:

.\vcpkg install lilv lv2

If you get an error about missing ports, you may need to update vcpkg first:

git pull
.\bootstrap-vcpkg.bat

Plugins

Lv2 plugins are not shipped with LMMS. This section shall describe which packages you need to install to get as many Lv2 plugins as possible.

Arch Linux

pacman -S calf lsp-plugins mda.lv2 noise-repellent surge x42-plugins
yay -S lv2-plugins-aur-meta

macOS (HomeBrew)

(to be done)

Ubuntu

# TODO: add more plugins
sudo apt-get install calf-plugins mda-lv2 x42-plugins swh-lv2

# Additional plugins for Ubuntu 20.04 or higher
sudo apt-get install lsp-plugins-lv2 dpf-plugins-lv2

Windows

You can download LV2 plugins from the internet. A good place to get started is https://x42-plugins.com/.

Supported plugins

Currently, we support

  • Core (except CV ports)
  • URIDs
  • MIDI atoms
  • Buffer Size
  • Options
  • Worker

Run LMMS_LV2_DEBUG <path to lmms> to get a complete list of unsupported plugins.

Debugging plugins

If a system-installed plugin has no debugging symbols, compile it and prepend the self-compiled version to the LV2_PATH:

LV2_PATH=/path/above/plugin/path:$LV2_PATH /path/to/lmms

For example, if you want to debug ZynAddSubFX, and it is in /a/b/c/ZynAddSubFX.lv2:

LV2_PATH=/a/b/c:$LV2_PATH /path/to/lmms

lv2lint

https://git.open-music-kontrollers.ch/~hp/lv2lint

If there isn't a package for it in your linux distro you will need to compile it from source. The lv2lint page above has an up to date description of this process.

By default lv2lint will look for plugins in LV2_PATH. For a complete list of options type lv2lint -h.

The simplest example command would be to just pass the plugin uri:

lv2lint http://calf.sourceforge.net/plugins/Vinyl

For a more extensive report:

lv2lint -d -E warn -E note http://calf.sourceforge.net/plugins/Vinyl
