Jamba is a set of helpers (classes, concepts, build files, etc...) built on top of the VST SDK to provide a lightweight framework to build a VST3 plugin. Jamba has been designed to help in building VST3 plugin, not to replace it: you are still writing a VST3 plugin, not a Jamba plugin.
Check the Jamba website for more details.
- generate a fully buildable, testable, editable and deployable plugin (see Quick Starting Guide)
- automatically download dependencies
- simple script to build, test, validate, edit and install the plugin from the command line (see jamba.sh (.bat)
- build a self-contained plugin that depends on the VST3 SDK
- optionally wraps the VST3 plugin into an Audio Unit plugin (macOS)
- build a universal plugin for Apple Silicon support (macOS)
- easily adds resources (images) in a cross-platform way
- easily write unit tests for your project
- build on macOS and Windows 10
- package your project as an archive (zip file) for production release
- pick and choose which feature is useful to you (lots of options to override/change the default behavior)
- 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 to allow easy state upgrade)
- Jamba Views

In order to work on this project itself (not a plugin), you need to clone this repository and install the VST3 SDK as described in the requirements section. In addition to the unit tests (under src/test), the embedded jamba-test-plugin plugin constitutes the main source of testing.
Although this project does not contain a great deal of tests, it is being heavily used (and as a result tested) by the plugins it has been designed to build.
| Plugin | Description |
|---|---|
| vst-ab-switch | A/B Audio Switch VST plugin |
| vst-vac-6 | VST (2 & 3) plugin to analyze and control the peak volume of a signal |
| vst-sam-spl-64 | A free/open source VST2, VST3 and AudioUnit plugin to easily split a sample in up to 64 slices |
| jamba-sample-gain | Documentation plugin for Jamba framework: a simple gain plugin for VST3 |
This project was created to abstract the common patterns and solutions to many questions implemented across the VAC-6V and A/B Switch vst plugins. Check Announcing Jamba blog post for more details.
