-The Synthesis ToolKit in C++ (STK)
-
-By Perry R. Cook and Gary P. Scavone, 1995-2012.
-
-The Synthesis ToolKit in C++ can be used in a variety of ways, depending on your particular needs.  Some people simmply choose the classes they need for a particular project and copy those to their project directory.  Others like to compile and link to a library of object files.  STK was not designed with one particular style of use in mind.
-
-To configure and compile (on Unix systems and MinGW):
-
-1. Unpack the STK distribution (tar -xzf stk-4.x.x.tar.gz).
-2. From within the directory containing this file, run configure:
-
-   ./configure
-
-3. From within each project directory, type "make".
-4. To compile a library of objects, type "make" from within the src directory.
-
-Several options can be passed to configure, including:
-
-  --disable-realtime = only compile generic non-realtime classes
-  --enable-debug = enable various debug output
-  --with-alsa = choose native ALSA API support (default, linux only)
-  --with-oss = choose native OSS API support (linux only)
-  --with-jack = choose native JACK server API support (linux and macintosh OS-X)
-  --with-core = choose OS-X Core Audio API (macintosh OS-X only)
-  --with-asio = choose ASIO API support (windows only)
-  --with-ds = choose DirectSound API support (windows only)
-
-It is now possible to specify more than one audio and MIDI API where supported.  Note, however, that the ALSA library is required in order to compile the RtMidi class in Linux if the "--with-oss" option is provided (only the OSS audio API will be used, not the OSS MIDI API).  Typing "./configure --help" will display all the available options.  In addition, it is possible to specify the RAWWAVES and INCLUDE paths to configure as (ex. to set to /home/me/rawwaves and /home/me/include):
-
-  ./configure RAWWAVE_PATH='$(HOME)/rawwaves/'
-  ./configure INCLUDE_PATH='$(HOME)/include/'
-
-The ending "/" is required for the RAWWAVES path.  The default behavior will set a relative path that works for the project files included with the distribution (assuming they are not moved).  You can also change the RAWWAVE_PATH dynamically via the static Stk::setRawwavePath() function.
-
-If you wish to use a different compiler than that selected by configure, specify that compiler in the command line (ex. to use CC):
-
-  ./configure CXX=CC
-
-
-For Windows Users:
-
-MinGW support is provided in the configure script.  In addition, Visual C++ 6.0 project files are included for each of the example STK projects, though these may not work with more recent versions of Visual Studio.

-The configure script supports MinGW.  As well, STK is distributed with Visual C++ .NET project and workspace files (though these may no longer work with current versions of Visual Studio).  It no longer compiles with Visual C++ 6.0.
+The configure script supports MinGW.
 
-With Windows XP/7, piping works as under unix.  Simply fire up the script files (ex. StkDemo.bat) by either double-clicking on them or from within a shell.
+STK has been built and tested on Windows platforms using Visual Studio.  It is assumed here that you're familiar with Visual C++ and its particular idiosyncrasies. The currently supported version is VS2017. You can download the free non-commercial community edition from the Microsoft website. The folders in the projects directory contain VS2017 solution files.
+If you are creating a new stk application, it's easiest to use the supplied template:
+- Copy stk\projects\stk-template.zip to C:\Users\<user>\Documents\Visual Studio 2017\Templates\ProjectTemplates\Visual C++ Project\
+- Start VS2017.
+- Select create new project...
+- Select Visual C++.
+- Select stk-template and enter your preferred project name and location. Note that if you do not put the project at the same level as stk\projects you will have to fix all paths in the project properties to match.
+- The template is based on one of the projects in the examples directory. Add/remove files as needed and edit main.cpp to taste.
 
-IMPORTANT VC++ NOTE: When compiling "release" versions of STK programs, link to the release multithreaded library.  When compiling "debug" versions, link to the debug multithreaded library.  Compiler errors will result otherwise.
+To use the Tcl/Tk GUIs, you will have to install Tcl/Tk and build using MinGW.
 
-Both the DirectSound and Steinberg ASIO audio APIs are supported for realtime audio input/output.  The Visual C++ project files included with this distribution are configured to use the DirectSound API.  In order to use the ASIO API, it is necessary to change the preprocessor definition from __WINDOWS_DS__ to __WINDOWS_ASIO__, as well as include all the files in the /src/include/ directory (i.e. asio.h, asio.cpp, ...).  If you have a good quality soundcard and a native ASIO driver (not emulated), you are likely to get much better input/output response using that.
+With Windows XP and later, piping works as under unix.  Simply fire up the script files (e.g. StkDemo.bat) by either double-clicking on them or from within a shell.
+
+The DirectSound, WASAPI and Steinberg ASIO audio APIs are supported for realtime audio input/output.  The VS2017 project files included with this distribution are configured to use all supported APIs.  The default (as in stk-template) is the DirectSound API (preprocessor definition __WINDOWS_DS__). In order to use the ASIO API, it is necessary to use the preprocessor definition __WINDOWS_ASIO__, as well as include most of the files in the /src/include/ directory (i.e. asio.h, asio.cpp, ...).  If you have a good quality soundcard and a native ASIO driver (not emulated), you are likely to get much better input/output response using that.
 
 When using the DirectSound API for audio input, latency can be high.  If you experience realtime audio "stuttering", you should experiment with different "buffer size" and "number of buffers" values.
 
 Realtime MIDI input/output is supported by RtMidi using the winmm.lib API and requires the __WINDOWS_MM__ preprocessor definition.
-
-Visual C++ workspaces have been created for the various STK projects.  Everything has already been configured for you.  The intermediate .obj files will be written to either the "Release" or "Debug" directories, but the executable files will be written to the main project directories (where they need to be for proper execution).  If you should somehow lose or hose the VC++ workspace file for a project, then you will have to do a LOT of configuring to recreate it ... it's probably easier just to download the distribution again from our WWW sites.  Anyway, for your benefit and mine, here is a list of things that need to be added to the various "Project Settings" (this was for VC 6.0 ... things have changed with the newer versions of the VC compiler):
-
-1. Under General: Set "Output files:" to <blank> (this will put the executable in the main project directory.
-
-2. Under C/C++ > Code Generation: Set "Use run-time library:" to Multithreaded (use "debug" versions for the debug configuration).
-
-3. Under Link > General:  Add winmm.lib, dsound.lib, and Wsock32.lib to the end of the Object/library modules list.
-
-4. Under C/C++ > Preprocessor: Add "../../include" directory to the "extra include" field.
-
-5. Under C/C++ > Preprocessor: Add "__WINDOWS_DS__", "__WINDOWS_MM__", and "__LITTLE_ENDIAN__ to the definitions field.
-
-6. Add all the necessary files to the project.
-
-Remember that items 1-5 above need to be done for each project and for each configuration.  There might be an easy way to make global changes, but I couldn't figure it out.
-
-To use the Tcl/Tk GUIs, you will have to install Tcl/Tk.

-STK has been tested on Windows platforms using the Visual .NET compiler

-
-The approach when using Visual C++ is to build a project that
-includes the necessary ToolKit files from the distribution
-<TT>src</TT> and <TT>include</TT> directories.  For the example
-program from the previous tutorial chapter, create a VC++ console
-application project, add the Stk, FileRead, FileWrite, WvIn, FileWvIn,
-FileLoop, WvOut, and FileWvOut class files, as well as
-<TT>sineosc.cpp</TT>, and make sure the <TT>sinewave.raw</TT> file is
-in the subdirectory <TT>rawwaves</TT>.
-
-For programs using any of the STK realtime classes mentioned above, it is necessary to link with the DirectSound (<TT>dsound.lib</TT>), <TT>winmm.lib</TT>, and <TT>Wsock32.lib</TT> libraries, select the multithreaded library, and provide the <TT>__LITTLE_ENDIAN__</TT>, <TT>__WINDOWS_DS__</TT>, and <TT>__WINDOWS_MM__</TT> preprocessor definitions.
-
-For Steinberg ASIO support, use the <TT>__WINDOWS_ASIO__</TT> preprocessor definition (and the <TT>__WINDOWS_MM__</TT> definition for RtMidi support), include all the files in the <TT>src/asio/</TT> directory (i.e., <TT>asio.h,cpp</TT>, <TT>asiodrivers.h,cpp</TT>, ...), and link with the <TT>winmm.lib</TT>, and <TT>Wsock32.lib</TT> libraries.

 <H4>What is the <I>Synthesis ToolKit</I>?</H4>
 
-The Synthesis ToolKit in C++ (STK) is a set of open source audio signal processing and algorithmic synthesis classes written in the C++ programming language.  STK was designed to facilitate rapid development of music synthesis and audio processing software, with an emphasis on cross-platform functionality, realtime control, ease of use, and educational example code.  The Synthesis ToolKit is extremely portable (it's mostly platform-independent C and C++ code), and it's completely user-extensible (all source included, no unusual libraries, and no hidden drivers).

Generic, non-realtime support has been tested under NeXTStep, Sun, and other platforms and should work with any standard C++ compiler.
 
-The Synthesis ToolKit is free.  The only parts of the Synthesis ToolKit that are platform-dependent concern real-time audio and MIDI input and output, and that is taken care of with a few special classes.  The interface for MIDI input and the simple <A HREF="http://dev.scriptics.com">Tcl/Tk</A> graphical user interfaces (GUIs) provided is the same, so it's easy to experiment in real time using either the GUIs or MIDI.  The Synthesis ToolKit can generate simultaneous SND (AU), WAV, AIFF, and MAT-file output soundfile formats (as well as realtime sound output), so you can view your results using one of a large variety of sound/signal analysis tools already available (e.g. <A HREF="http://www-ccrma.stanford.edu/software/snd/">Snd</A>, Cool Edit, Matlab).

 <H4>What the <I>Synthesis ToolKit</I> is not.</H4>
 
 The Synthesis Toolkit is not one particular program.  Rather, it is a set of C++ classes that you can use to create your own programs.  A few example applications are provided to demonstrate some of the ways to use the classes.  If you have specific needs, you will probably have to either modify the example programs or write a new program altogether. Further, the example programs don't have a fancy GUI wrapper.  It is easy to embed STK classes inside a GUI environment but we have chosen to focus our energy on the audio signal processing issues.  Spending hundreds of hours making platform-dependent graphical user interfaces would go against one of the fundamental design goals of the ToolKit - platform independence.
 
-For those instances where a simple GUI with sliders and buttons is helpful, we use <A HREF="http://dev.scriptics.com">Tcl/Tk</A> (that is freely distributed for all the supported ToolKit platforms).

 The Synthesis ToolKit is a set of C++ classes.  In order to go beyond the simple example programs we provide, it is necessary to know some basics about programming in C and C++.  STK's "target audience" includes people who:

+- want to use our unit generators and input/output routines rather than code their own
+- want to learn about synthesis and processing algorithms
+- wish to teach real-time synthesis and processing and wish to use some of our classes and examples
 
 Most ToolKit programmers will likely end up writing a class or two for their own particular needs, but this task is typically simplified by making use of pre-existing STK classes (filters, oscillators, etc.).

+
+## Setup
+
+### [CocoaPods](https://cocoapods.org) (Recommended)
+
+1. Add `pod 'STK', '~> 4.6'` to your Podfile.
+
+1. Run `pod install`
+
+### Manual
+
+1. Clone or [download][download_link] the STK into your project's directory.
+
+1. Open the **STK for iOS** folder, and drag and drop **STK.xcodeproj** into your Xcode project.
+
+1. Open your project's settings, open the *Build Phases* tab. In the *Link Binary with Libraries* section, add **libSTK.a**.
+![][linking_libSTK_screenshot]
+
+1. In the *Dependencies* section, add "rawwaves"
+
+1. In your project's settings, open the *Build Settings* tab. In the *Search Paths* section, double click on the field to the right of *Header Search Paths*, and add the path to the STK's **include** directory relative to your Xcode project's directory.
+![][header_search_paths_screenshot]
+
+
+## Usage
+
+1. Import the STK classes you require in your Objective-C source files (Swift does not yet support importing C++ code)
+  * E.g. `#import "SineWave.h"`
+
+1. Change the extension of any Objective-C files that import STK files to **.mm**.
+  * E.g. **ViewController.m** —> **ViewController.mm**
+
+1. If you use a class that makes use of raw wave files (such as `Mandolin`), make sure you call `Stk::setRawwavePath` beforehand in your code.
+
+See the [iOS Demo project](..projects/demo/iOS%20Demo) for a sample usage.
+
+
+## Troubleshooting
+
+### 'FileName.h' file not found
+
+If you get this error when `#import`ing an STK header, you have added the wrong header search path for the STK in your project's settings (see Step 4 in Setup)
+
+The STK's header search path you need to add is the path to the STK's **include** directory relative to your project's directory (as if you were `cd`ing into it). For example, it is `stk/include/` if the stk directory is inside your project's directory, but it is `../stk/include/` if both share the same directory.
+
+If this problem doesn't go away:
+
+1. Delete **STK.xcodeproj** from your Xcode project
+1. Move the STK directory within your project's directory.
+1. Follow step 1 from **Setup**, add `stk/include` to the *Header Search Paths*.
+
+If that doesn't solve it:
+Install CocoaPods and use it to install the STK. It takes one minute and will make your life easier. Visit the [CocoaPods website](https://cocoapods.org) for installation instructions.
+
+### FileRead::open: could not open or find file (../../rawwaves/filename.raw)!
+
+If you use a class that makes use of raw waves (such as `Mandolin`, `Wurley`, or `Rhodey`) you need to make sure that the STK's raw wave files are copied into your bundle and that the STK knows where they are. You'll know you need to if you get this runtime error:
+`FileRead::open: could not open or find file (../../rawwaves/filename.raw)!`
+
+#### If you're using CocoaPods
+
+Add this code before using a class that needs the raw waves:
+```objective-c
+stk::Stk::setRawwavePath([[[NSBundle mainBundle] pathForResource:@"rawwaves" ofType:@"bundle"] UTF8String]);
+```
+
+#### If you're not using CocoaPods
+
+1. Open your project's settings, open the *Build Phases* tab.
+1. In the *Copy Bundle Resources*, drag and drop **rawwaves.bundle** (it's located in **STK.xcodeproj**'s **Helpers** folder).
+1. Then add this code before using a class that needs the raw waves:
+
+```objective-c
+NSBundle *rawwaveBundle = [NSBundle bundleWithURL:[[NSBundle mainBundle] URLForResource:@"rawwaves" withExtension:@"bundle"]];
+stk::Stk::setRawwavePath([[rawwaveBundle resourcePath] UTF8String]);
+```
+
+### Apple Mach-O Linker Error
+
+This means that **STKLib.a** isn't being linked to your binary. Follow step 2 above in [Setup](#setup).

+##iOS Demo Xcode project

+This project briefly shows how to manually integrate the STK static library into an Xcode project. See the **README** file in the STK's `iOS` directory for precise instructions.
+
+Currently, this project does not output sound, it only shows how to generate audio samples from the STK classes within an iOS project, and how to control STK objects via UI controls. These samples need to be fed into an audio engine for them to be heard.

+ * The header search paths in the *Build Settings* of **iOS Demo.xcodeproj** point to `../../include/` because the STK's `include` directory is two directories up relative to it.
