Hi everyone

I wanted to announce the release of a new, free and open source, VST (2/3) framework called Jamba. The framework is built on top of the VST3 SDK and offers the following set of features:
  • * by including jamba/jamba.cmake in your project you gain access to the following
    • * include all the necessary files so that your project depends on the VST SDK (including support for VST2)
      * easily write unit tests for your project (using googletest)
      * build on macOS and Windows 10 (Linux untested but support could be added)
      * package your project as an archive (zip file) for production release
      * scripts to build, test, validate, edit and install the plugin from the command line
    * pick and choose which feature is useful to you
    * define your VST parameters in one location (inherit from Parameters) and use both in real time processing (RT) and GUI code
    * define typed VST parameters (ex: a boolean (bool) parameter, a gain (Gain) parameter, etc...)
    * use typed VST parameters directly in RT processing code as well as GUI code
    * use Jamba parameters for handling non VST parameters (ex: a label/text string cannot be represented by a VST parameters). Jamba parameters can be automatically saved/restored part of the state
    * use Jamba parameters to easily exchange messages between RT and GUI (both directions) in a thread safe fashion
    * easily create custom views with their creators (so that they appear in the GUI editor)
    * easily use multiple parameters in a custom view (ex: a custom display which displays a gain value (parameter 1) in a color depending on parameter 2)
    * store/read state in a thread safe fashion (includes version)
    * UI views: toggle button and momentary button with 2 or 4 frames, Text Edit (with input saved part of the state)
    * Generates a fully buildable, testable, editable plugin with a simple command
I am emphasizing the last line because you really get a fully working VST2/3 plugin with a single command... all the boilerplate code (including generating the FUIDs), scripts, makefile, etc... is generated for you.

You can check Jamba at

The project jamba-sample-gain is a rewrite of the again plugin (that comes with the SDK) using Jamba to demonstrate and document the various features.
