 The Synthesis ToolKit in C++ can be used in a variety of ways, depending on your particular needs.  Some people simply 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.

 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.

-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.
 
-The DirectSound, WASAPI 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 all supported APIs.  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.

+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.

@@ -20,14 +20,14 @@ Here's a link to a book that includes an chapter on STK.
 
 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).  We like to think that this increases the chances that our programs will still work in another 5-10 years.  In fact, the ToolKit has been working continuously for nearly 20 years now.  STK currently runs with realtime support (audio and MIDI) on Linux, Macintosh OS X, and Windows computer platforms.  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).
