Extensions

From Lv2

[edit] "Good" Extensions

These extensions have been discussed and reviewed by the community, and implemented in released software.

• Good extensions at http://lv2plug.in/ns/ext
• Good extensions at http://lv2plug.in/ns/extensions

• Progress - Reporting progress of lengthy operations (e.g. plugin instantiation)
• ExternalUIExtension - Launching plugin UI in separate process
• rtmempool - Realtime safe memory allocation for use by plugins, implemented in host
• dynparam - Dynamic plugin parameters (parameters can appear/disappear at runtime)

[edit] Draft Extensions

These extensions are for discussion and experimentation only, and are not NOT stable. Released software should not make use of these extensions.

• Draft extensions at http://lv2plug.in/ns/dev

• Extended port information
• Mixing control
• Ideas for new extensions - uncensored edition
• MessageExtension
• Plugin-side presets - the way for a plugin to manage its own presets (allowing cross-standard presets, "factory" presets, and sharing presets between hosts)
• Replace plugin - to avoid displaying LV2 and LADSPA versions of the same plugin (also, to hide old backward-compatible versions)
• Lars Luthman's extensions
  • Save/Restore (plugin state serialization)
  • MIDI Map (assigning constant controller numbers to parameters)
  • Port groups (semantic grouping of LV2 ports)
  • UI (generic user interface extension + GTK+ variant)
  • GUI preset access - need to find that one

[edit] Obsolete Extensions

• MidiPort - MIDI datatype, superseded by Events and MIDI Events
• More units - Incorporated into Units
• Name and version - Obsoleted by (provisional) LV2r4
