This site hosts the specifications for the LV2 extension namespaces defined by MOD Audio. They are open, ISC licensed and free to use in any plugin. These extensions complement the standard LV2 core vocabulary and are used by plugin developers targeting MOD-powered platforms (MOD Duo, MOD Duo X, MOD Dwarf, MOD Desktop).
The base vocabulary. Every plugin or pedalboard file targeting a MOD platform builds against one or more of these — permanent, and never repurposed once published.
| Prefix | Canonical URI | Spec | Used by |
|---|---|---|---|
mod: |
http://moddevices.com/ns/mod# |
View spec | Plugin developers — brand, label, port overrides, CV ports |
modgui: |
http://moddevices.com/ns/modgui# |
View spec | Plugin developers — custom HTML/CSS GUI for the pedalboard canvas |
modpedal: |
http://moddevices.com/ns/modpedal# |
View spec | Tool authors — pedalboard bundle format (written by mod-ui, not by plugin developers) |
ns/ext/*)
Discrete, optional features that aren't part of the core vocabulary — each one published
under its own ns/ext/<feature> path once adopted. A plugin or platform
only needs to know about the extensions it actually uses.
| Prefix | Canonical URI | Spec | Used by |
|---|---|---|---|
mod:license |
http://moddevices.com/ns/ext/license# |
View spec | Plugin developers — copy-protection and trial mode protocol |
hmi: |
http://moddevices.com/ns/hmi# |
View spec | Plugin developers — drive the hardware display and LEDs for an addressed parameter (MOD devices only). Its URI predates the ns/ext/ convention and stays where shipped plugins expect it. |
Three tiers, by who may write a term into files that live on users' devices:
mod:, modgui:, modpedal:):
defined by MOD. A published term is never given a second meaning.ns/ext/<feature>#, and ns/hmi#):
a discrete feature, proposed by a contributor or by MOD, published here when the feature is
adopted into the MOD platform.
The gate is on writing: a change that only reads new terms is accepted on normal
review; a change that writes a new term into pedalboard files needs the term published on
this site first, with the pedalboard format version
bumped. See CONTRIBUTING.md in
mod-ui.
See the MOD Plugin SDK for building, validating and installing plugins, metadata, custom GUIs (modgui) and known caveats.
