The VST SDK, which allow a user to create audio plugins that can be used inside of most major DAWs. The VST SDK is available free of charge, making it an ideal choice for this project, which had no budget. I decided to implement this project as a set of Virtual Studio Technology (VST) plugins. VST is a format created by Steinberg GmbH ( ^3. Party Developer ). It consists of a set of C libraries known as the VST SDK, which allow a user to create audio plugins that can be used inside of most major DAWs. This plugin makes it easy to create some of your favourite bass sounds with ease with two channels; it gives you the ability to change the width, filter, filter q, and LFO. Including three windows sound, pattern, and effects, this gives you full control over the noise generated, the pattern it plays in tempo sync, and the rest being applied to.

Introduction

Develope A Vst Plugins

Developing VST plugins under Mac OSX is in many ways simpler than other platforms, but nonetheless there are a few “gotchas” along the way.

This guide assumes familiarity with Xcode and C++ development, and that you are working with Mac OSX 10.5 or greater and have a relatively recent version of Xcode (4.2 or better). This guide only covers building VST 2.x plugins, as the VST3 SDK is not widely supported yet.

Develop Vst Plugins

Develop

Also, before you start, you will obviously need the VST SDK, which can be acquired from Steinberg’s Development Portal. Note that Steinberg’s website is a bit confusing and does not label the downloads clearly, so make sure that you get the right version of the SDK.

Creating your project

First, create a new empty Xcode project. Now add a new target to the project, which should use the “Bundle” template under the “Framework & Library” group (for Mac OS X, of course). Set the product name, bundle identifier, and choose to link it against the Cocoa Framework.

Adding resource files

Create a new empty file in your project named “PkgInfo” with the contents “BNDL????” (no quotes, and no newline either). You can verify that this file will be copied to the VST bundle by clicking on your project’s target in the file browser, and then expanding the “Copy Bundle Resources” section underneath “Build Phases”.

When you created the project, Xcode should also have created a property list (plist) file for you. Open the plist file for editing, and right click anywhere in document body to change the view type to “Show Raw Keys/Values”. Now, set the following properties, adding new keys if necessary:

  • CFBundleDevelopmentRegion: English
  • CFBundleExecutable: vst
  • CFBundleGetInfoString: vst
  • CFBundleIconFile: (empty)
  • CFBundleIdentifier: com.yourcompany.pluginname
  • CFBundleInfoDictionaryVersion: 6.0
  • CFBundlePackageType: BNDL
  • CFBundleSignature: (A unique 4-character identifier of your choosing)
  • CFBundleVersion: 1.0
  • CSResourcesFileMapped: (empty)

Adding the VST SDK files

Create a new group for the VST source files, and drag them from the Finder into your project. Do not drag the entire vstsdk2.4 folder into your project. Make sure that the subfolders for “pluginterfaces” and “public.sdk” (excluding the samples) are in the project.

Now, in the project’s properties, go to the “Search Paths” section and add the vstsdk2.4 directory to the “Header Search Paths” setting. Make it recursive.

Project build settings

Unless you have very specific requirements, I highly recommend building your plugin as a standard 32-bit Intel binary. My reasoning for this is as follows:

  • Although 64-bit Macs are widespread, there are not so many 64-bit compatible plugin hosts, though this is slowly changing.
  • Likewise, building 64-bit VST’s is sometimes a bit difficult, as Apple is deprecating Carbon, which is 32-bit only.
  • The number of PPC users out there is not so many anymore, so building a 32-bit Universal Binary is probably overkill.

Develop Vst Plugin

You can set the build type in the “Architectures” section, and again I recommend setting this to “32-bit Intel”. If anyone can get VST2.4 plugins building as 32/64 bit UB’s, please let me know so I can adapt this documentation to include how to do this.

Next, set the Base SDK to “Current Mac OS”. This will make it much less painful when opening the project in future versions of Xcode. In the “Deployment” section, set “Mac OS X Deployment Target” to the oldest version of Mac OS X you plan to support. Setting it to “Compiler Default” is likely to get you into trouble.

Under “Packaging”, make sure that both “Executable Extension” and “Executable Prefix” are empty. Set “Wrapper Extension” to be “vst”.

Frameworks

Again, in your target’s settings, go to the “Build Phases” tab and expand the “Link Binary With Libraries” section. Add the following libraries to your project:

  • QuickTime
  • Carbon
  • ApplicationServices

Your source code

Now you are ready to add or create files for your plugin’s source code.
