This is an in progress hard fork of DPF. The goal is to create a C friendly interface for building plugins across multiple formats. The API will undergo radical changes, and a few things will likely be broken or deprecated (State API, cairo, opengl, linux support)
Eventually I will add support for standalone builds and possibly the FL Studio plugin format.
The original DPF license remains the same, read it and follow da rules. As for all my original code here IDGAF it's public domain.
DPF is designed to make development of new plugins an easy and enjoyable task.
It allows developers to create plugins with custom UIs using a simple C++ API.
The framework facilitates exporting various different plugin formats from the same code-base.
DPF can build for LADSPA, DSSI, LV2, VST2, VST3 and CLAP formats.
A JACK/Standalone mode is also available, allowing you to quickly test plugins.
Plugin DSP and UI communication is done via key-value string pairs.
You send messages from the UI to the DSP side, which is automatically saved in the host when required.
(You can also store state internally if needed, but this breaks DSSI compatibility).
Getting time information from the host is possible.
It uses the same format as the JACK Transport API, making porting some code easier.
Provided features and implementation status for specific plugin formats can be seen in FEATURES.md.
DPF is released under ISC, which basically means you can do whatever you want as long as you credit the original authors.
Some plugin formats may have additional restrictions, see LICENSING.md for details.
Bug reports happen on the DPF github project.
Online documentation is available at https://distrho.github.io/DPF/.
Online help and discussion about DPF happens in the kx.studio chat, DPF room.
See this wiki page for a list of plugins made with DPF.
Plugin examples are also available in the example/ folder inside this repo.
