Open Sound Control inside LV2 plugin graphs
This LV2 plugin bundle allows you to handle OSC (Open Sound Control) bundles and messages in modular hosts.
- Insert/dispatch OSC from/to UDP, TCP (IPv4/6) and serial sockets
- Pack/unpack MIDI into OSC
- Pack/unpack OSC into MIDI
- Pack/unpack LV2 atoms into OSC
Makes only sense to be used in hosts that allow routing of LV2 atom messages between plugins, e.g.

lv2lint
Check whether a given LV2 plugin is up to the specification
An LV2 lint-like tool that checks whether a given plugin and its UI(s) match up with the provided metadata and adhere to well-known best practices.
Run it as part of your continuous integration pipeline together with lv2/sord_validate to reduce the likelihood of shipping plugins with major flaws in order to prevent unsatisfied users.
Note: This is an early release, if you happen to find false-positive warnings when using this tool, please report back, so it can be fixed.

Moony
Realtime Lua as programmable glue in LV2
Write LV2 control port and event filters in Lua. Use it for one-off fillters, prototyping, experimenting or glueing stuff together.
Packages
General Overview
The Moony plugins come in three flavours, whereby some of them are more and others less suitable for linear plugin hosts (e.g. DAWs). All of them are suitable for non-linear hosts (NLH), e.g. Ingen or Synthpod.
- Control to control port conversion (NLH)
- Atom to atom port conversion (DAW, NLH)
- Control+atom to control+atom port conversion (DAW, NLH)
The design goal of the plugin bundle was to create a tool to easily add realtime programmable logic glue in LV2 plugin graphs.
To have plugins which do a specific task efficiently is great, especially for audio plugins. LV2 stands apart from other audio plugin specifications with its extentable event system based on Atoms. As events can be much more varied in nature and represent pretty much anything (NOT ONLY MIDI), it would be useful to have a tool to create arbitrary event filters for a given setup on-the-fly.
For a given setup, one may need a special event filter only once and it seems to be overkill to write a native LV2 event filter in C/C++ just for that. It would also be nice to have a tool for fast prototyping of new event filters.
A scripting language seems to be ideal for these cases, where the user can write an event filter on a higher level of abstraction on-the-fly. The scripting language needs to be realtime safe, though, which restricts the choices dramatically.
One such scripting language is Lua. It is small, fast, easily embeddable and realtime-safe if coupled to a realtime-safe memory allocator like TLSF.
The Moony plugins can handle LV2 control and atom event ports, only. They do not handle LV2 audio ports. They may eventually handle LV2 control-voltage ports in the future, though. Control port values are internally handled as simple floating point numbers, whereas the atom event ports build on top of the LV2 atom and atom forge C headers.
The control port plugins are simple to script and need only low level programming skills.
The atom event port plugins are more complex. You may want to first understand the underlying concepts of LV2 atom and atom forge in the official resources:
