These examples all serve as templates, which can be duplicated to form the start of your project.

There are three examples you should check out first:

• IPlugEffect : A basic audio effect which is a volume control.
• IPlugInstrument : An MPE-capable polyphonic synthesiser.
• IPlugControls : A demonstration of the widgets available in the IControls library.

The following examples are more specialized:

• IPlugChunks : Shows how to store data other than just parameter values in the plug-in state and how to get tempo info from the host.

• IPlugMidiEffect : A basic MIDI effect plugin. Note: only AudioUnits really have a notion of a midi effect.

• IPlugSideChain : Demonstrates how to do a plug-in with two input buses for effects that require sidechain inputs such as compressors/gates.

• IPlugSurroundEffect : A multichannel volume control effect plug-in that should work on different surround buses.

• IPlugDrumSynth : A drum synthesiser example with multiple output buses.

• IPlugResponsiveUI : An example of how to make a responsive UI that adapts to the platform window that can be maximized and resized using the OS window chrome.

• IPlugOSCEditor : Demonstrates how to use the Open Sound Control classes in iPlug2, as well as the IWebViewControl

• IPlugReaperExtension : This is a template project for making a Reaper Extension. No realtime audio processing code, obviously. Making a reaper extension can be painful since it is all based around the Win32 APIs. This abstracts away some of the nastyness.

• IPlugReaperPlugin : This is a plugin that calls Reaper API functions Reaper Extension. Supports VST2, VST3 and CLAP formats.

• IPlugConvoEngine : UI-less example of WDL_ConvoEngine that reports a delay to the host for plugin-delay-compensation (PDC)

• IPlugCocoaUI : An iOS/macOS project using AppKit/UIKit for the user interface

• IPlugSwiftUI : An iOS/macOS only project using SwiftUI for the user interface

• IPlugWebUI : An example showing how UI can written in HTML/CSS/JS, using a platform web view
