This change reshuffles the way that parameter updates and notifications work for hosted VST3 plugins. Previously: - Parameter::setValue would update the processor and editor, but not the host - Parameter::setValueFromEditor would update the processor and host, but not the editor - MIDI CC events would be converted to events and added to the processor's input event list, but were not forwarded to the IEditController. Now: - Parameter::setValue updates the host's cachedParamValues, which is the host's source of truth for parameter values. On each process callback, changes will be added to the input parameter list. Then, for each item in the parameter list, an update will be dispatched back to the editor. - Parameter::setValueFromEditor is removed. All parameter changes will be sent back to the editor, even if they originated from the editor. setValueNotifyingHost can be used to notify listeners that one of the host's JUCE parameters has changed, e.g. in the host context's performEdit. - MIDI CC events trigger calls to setValueNotifyingHost on any mapped parameters. The flow is very similar to a parameter change from the editor: the cachedParamValues are updated immediately, and host parameter listeners are notified. Then, for each changed cachedParamValue an entry is added to the inputParameterChanges (updating the processor), then for each item in the inputParameterChanges an update is sent to the editor. |

JUCE is an open-source cross-platform C++ application framework for creating high quality desktop and mobile applications, including VST, VST3, AU, AUv3 and AAX audio plug-ins. JUCE can be easily integrated with existing projects via CMake, or can be used as a project generation tool via the Projucer, which supports exporting projects for Xcode (macOS and iOS), Visual Studio, Android Studio, Code::Blocks and Linux Makefiles as well as containing a source code editor.
Getting Started
The JUCE repository contains a master and develop branch. The develop branch contains the latest bugfixes and features and is periodically merged into the master branch in stable tagged releases (the latest release containing pre-built binaries can be also downloaded from the JUCE website).
JUCE projects can be managed with either the Projucer (JUCE's own project-configuration tool) or with CMake.
The Projucer
The repository doesn't contain a pre-built Projucer so you will need to build it for your platform - Xcode, Visual Studio and Linux Makefile projects are located in extras/Projucer/Builds (the minimum system requirements are listed in the System Requirements section below). The Projucer can then be used to create new JUCE projects, view tutorials and run examples. It is also possible to include the JUCE modules source code in an existing project directly, or build them into a static or dynamic library which can be linked into a project.
For further help getting started, please refer to the JUCE documentation and tutorials.
CMake
Version 3.15 or higher is required. To use CMake, you will need to install it, either from your system package manager or from the official download page. For comprehensive documentation on JUCE's CMake API, see the JUCE CMake documentation. For examples which may be useful as starting points for new CMake projects, see the CMake examples directory.
Building Examples
To use CMake to build the examples and extras bundled with JUCE, simply clone JUCE and then run the following commands, replacing "DemoRunner" with the name of the target you wish to build.
cd /path/to/JUCE
cmake . -B cmake-build -DJUCE_BUILD_EXAMPLES=ON -DJUCE_BUILD_EXTRAS=ON
cmake --build cmake-build --target DemoRunner
Minimum System Requirements
Building JUCE Projects
- macOS/iOS: Xcode 10.1 (macOS 10.13.6)
- Windows: Windows 8.1 and Visual Studio 2015 Update 3 64-bit
- Linux: g++ 5.0 or Clang 3.4 (for a full list of dependencies, see here).
- Android: Android Studio on Windows, macOS or Linux
Deployment Targets
- macOS: macOS 10.7
- Windows: Windows Vista
- Linux: Mainstream Linux distributions
- iOS: iOS 9.0
- Android: Jelly Bean (API 16)
