Release notes

Keep up with major changes here: Release Notes



Dplug has a deep commitment to stability. All breaking changes are documented in the Changelog and issues major SemVer tags for breaking changes. If you don't want any breaking changes, you can pin Dplug to a major version in your dub.json. Breaking changes only happen for major tags.

Dplug's goal is to support existing products and building commercial companies around them. It is a part-time operation, from people who release commercial plug-ins.

Being stable and relatively bug-free is deemed more important to us than implement every possible feature. It's often than enhancements get postponed in favour of product development, so please be patient!

Be sure to read the Wiki in depth.

Strengths of Dplug

  • As lightweight as possible
  • Public bugtracker
  • Well-defined scope: for professional plug-in developers
  • Maintained continuously, supported by sales for the foreseeable future
  • Price is free, no personal support must be expected though
  • Intel intrinsics compatible with Apple Silicon
  • Fast 2D software rasterizer in dplug:canvas
  • PBR-style rendering lets you have a good visual quality with less disk space. If you don't use it, you don't pay for it.
  • No dealing with resource compilers: D can import("filename.ext") them
  • Easy to install and update
  • Constant push to fight complexity


If you don't have the VST SDK, you can't make VST plugins with Dplug. Find the VST SDK there: http://www.steinberg.net/en/company/developers.html

If you don't have a licensing agreement with Steinberg, you can't distribute VST2 or VST3 plug-ins.


Dplug has many different licenses depending on the sub-package you need. Please check individual source files for license information. Please do your homework and respect the individual licences when releasing a plug-in.
