The Synthesis ToolKit in C++ (STK)
By Perry R. Cook and Gary P. Scavone, 1995-2009.
The Synthesis ToolKit in C++ can be used in a variety of ways, depending on your particular needs. Some people just 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 API where supported. Note however that the ALSA library is required in order to compile the RtMidi class, even 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/gary/rawwaves and /home/gary/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
In addition, a linux RPM is available from the Planet CCRMA WWW site (http://ccrma.stanford.edu/planetccrma/software/).
For Windows Users:
MinGW support is provided in the configure script. In addition, Visual C++ project files are included for each of the example STK projects.

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.
## Unix systems and MinGW
1. If you downloaded the software from the git repository, first run autoconf,
autoconf
otherwise, if you downloaded the software from the STK source distribution, unpack the tar file,
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 (unixes only)

--with-asio = choose ASIO API support (windows only)
--with-ds = choose DirectSound API support (windows only)
--with-wasapi = choose Windows Audio Session 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
## Windows
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.
##iOS
You can integrate the STK in iOS projects either by using its iOS static library or Cocoapods. See the [iOS README file](iOS/README-iOS.md) for instructions.

Realtime audio support for Linux currently includes the Advanced Linux Sound Architecture (ALSA), the JACK low-latency audio server, and/or Open Sound System (OSS version 4.0 and higher only) APIs. That said, the OSS API support has not been tested in several years and is not considered a high priority. One or more APIs are selected during compilation using the __LINUX_ALSA__, __UNIX_JACK__, and/or __LINUX_OSS__ definitions. Because the ALSA library is now integrated into the standard Linux kernel, it is the default audio/MIDI API with STK versions 4.2 and higher.

The __LINUX_ALSASEQ__ definition is required to compile RtMidi with ALSA sequencer support. Native OSS MIDI support no longer exists in RtMidi. If the __LINUX_OSS__ preprocessor definition is specified, only OSS audio support will be compiled and RtMidi will still be compiled using the ALSA API. For this reason, STK now requires the asound library for realtime support. Realtime programs must also link with the pthread library. The OSS audio API can be selected by passing the "--with-oss" option to configure.

MIDIATOR SERIAL PORT MIDI SUPPORT:
MIDIator support has been removed from RtMidi with STK versions 4.2 and higher. If you really need it, you can contact us to get an old distribution.
NOTE REGARDING PTHREADS:
There haven't been any problems with threads since the old days of RedHat Linux 5.0. STK uses the MIT pthreads API.

The default realtime support for Macintosh OS X uses the CoreAudio HAL API and is specified during compilation using the __MACOSX_CORE__ preprocessor definition. There is also support for the JACK audio server using the __UNIX_JACK__ preprocessor definition.
It is necessary to install the OS X developer kit (or the command line tools) in order to compile STK. STK was successfully tested on the latest version of OS X.
It is necessary to install the OS X developer kit in order to compile STK. STK was successfully tested on OS X versions 10.5.
The internal Macintosh audio hardware typically supports a sample rate of 44100 Hz only. The default STK sample rate is now 44100 Hz and all current example programs use this rate. However, it is possible to manually override this value in some programs from the command-line. The default sample rate is set in Stk.h. In addition, the RT_BUFFER_SIZE, specified in Stk.h, could be increased (to a higher power of two) for more robust performance.
There is a potential conflict between the STK Delay class and a Delay() function declared in OSUtils.h (which is included via <CoreServices/CoreServices.h>). In general, this conflict can be avoided via the use of a namespace (an explicit Delay::Delay declaration), though this made the Windows Visual C++ compiler barf. If you use STK classes within a project that includes the OSUtils.h file, you will likely need to make changes in STK classes that use the Delay class.
Tcl/Tk on OS X:
I think that tcl/tk interpreter is now included in the XCode package, since I haven't had to download it for several years now.
The tcl/tk interpreter does not ship by default with OS X, but must be downloaded from the internet. The latest Tcl/Tk Aqua distribution (http://www.apple.com/downloads/macosx/unix_open_source/tcltk.html) has been successfully tested on 10.2 and 10.3 systems. The default installation will place a link to the wish interpretor at /usr/bin/wish.
It appears that socket support in Tcl/Tk on OS X uses the Nagle algorithm, which produces poor response between changes made in the tcl/tk script and the resulting audio updates. Note that this is only a problem when using a socket connection from a Tcl/Tk script.

STK has always worked under NeXTStep without realtime audio or MIDI support. In general, STK should compile in this way using any generic C++ compiler. C++ exception handling was added to STK with release 3.2. We managed to get a version of gcc compiled for NeXTStep that can deal with C++ exceptions.

Since STK version 4.3, realtime support for IRIX has been discontinued due to an inability to test it. If you need realtime support on an SGI, go back to version 4.2.1. Release 4.0 of STK is confirmed to compile (with various warnings) using CC version 7.30.
The project Makefiles are created by configure. If you have trouble running "make", try invoking "gmake" (for GNU make). If that doesn't work, try to download the GNU Makefile utilities from the Internet.

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.

-----------------------------
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 is currently distributed with Visual C++ .NET project and workspace files. It no longer compiles with Visual C++ 6.0. I gave up attempting to fix all the problems created by such a bad compiler. This version of STK has been tested using Visual C++ .NET. As well, the configure script now supprots MinGW.
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.
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. Also, the Microsoft folk are up to their old habits of trying to change standards. The .NET compiler will complain about cerr for some reason.
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.
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.
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.
When using the DirectSound API for audio input, latency is typically pretty horrendous (should we be surprised?). Also, there is a slight chance you don't have DirectSoundCapture support on your computer. If not, you should download the DirectX 6.0 (or higher) runtime libraries from Microsoft's WWW site (http://www.microsoft.com/directx/download.asp) in order to run the pre-compiled STK executables for Windoze. The last time I checked, there was no DirectSoundCapture support for WindowsNT ... you'll have to switch to Windows 2000 or XP or use an ASIO driver. I stopped supporting the WinMM audio output code with release 3.2.
Realtime MIDI input/output is supported by RtMidi using the winmm.lib API and requires the __WINDOWS_MM__ preprocessor definition.

WINDOWS XP/2000:
There is a big advantage in using Windows XP/2000 over 95/98 with STK in that piping works, just as under unix. Also, the scheduler in 2000/XP seems to be much better, so socketed messages don't get clumped together like they do in Windows 95/98. Simply fire up a script file (ex. StkDemo.bat) by either double-clicking on it or typing it within a shell.
WINDOWS 95/98:
PLAY SKINI SCOREFILES IN REALTIME:
demo Clarinet -or -if scores/streetsf.ski
USE TCL/TK GUIs FOR REALTIME CONTROL:
1. Open a DOS console window and start syntmono (eg. demo Clarinet -or -is).
2. Double click on a Tcl/Tk file in the tcl/ subdirectory of the demo directory (eg. Demo.tcl) from the Windows Explorer to start the GUI. Select the "communications" menu item and "Socket" and make the connection.
3. Start moving the sliders to control the instrument.
USE REALTIME MIDI INPUT FOR CONTROL:
1. Open a DOS console window and start syntmono with MIDI input (eg. demo Clarinet -or -im).
This assumes you already have MIDI setup correctly for your computer.
WINDOWS NT ONLY:
Realtime piping seems to work under WindowsNT in much the same way as on Unix platforms. Thus, it is possible to pipe realtime control data to syntmono under WindowsNT as well. Note, however, that the DirectSoundCapture API does not exist for WindowsNT, so it is necessary to use an ASIO audio driver and the STK ASIO support.

\subsection v2dot02 Version 2.02
- Created RawWave abstract class, with subclasses of RawLoop (looping rawwave oscillator), RawShot (non-looping, non-interpolating rawwave player ... used to be RawWvIn), and RawInterp (looping or non-looping, interpolating rawwave player ... used to be RawWave).
- Modified DrumSynt to correctly handle sample rates different than 22050 Hz.
- Modified syntmono parsing vs. tick routine so that some ticking occurs between each message. When multiple messages are waiting to be processed, the time between message updates is inversely proportional to the number of messages in the buffer.
- Fixed DirectSound playback bug in WinXX distribution. Sound was being played at 8-bit, 22 kHz in all cases. Playback is now 16-bit and dependent on SRATE.
- Fixed bug in MD2SKINI which prevented some NoteOff statements from being output.
- This distribution includes an example STK project, mus151, which demonstrates a means for keeping a user's personal projects separate from the main distribution. This is highly recommended, in order to simplify upgrades to future STK releases.

\subsection v2 Version 2
- Unification of the capabilities of STK across the various platforms. All of the previous SGI functionality has been ported to Linux and Windows, including realtime sound output and MIDI input.
- MIDI input (with optional time-stamping) supported on SGI, Linux (OSS device drivers only), and Windows operating systems. Time stamping under IRIX and Windows is quantized to milliseconds and under Linux to hundredths of a second.
- Various Sound Output Options - .wav, .snd, and .mat (Matlab MAT-file) soundfile outputs are supported on all operating systems. I hacked out the MAT-file structure, so you don't have to include any platform-specific libraries. Realtime sound output is provided as well, except under NeXTStep.
- Multiple Reverberator Implementations - Reverb subclasses of JCRev and NRev (popular reverberator implementations from CCRMA) have been written. Perry's original reverb implementation still exists as PRCRev. All reverberators now take a T60 initializer argument.
- MD2SKINI - A program which parses a MIDI input stream and spits out SKINI code. The output of MD2SKINI is typically piped into an STK instrument executable (eg. <tt>MD2SKINI | syntmono Clarinet -r -i</tt>). In addition, you can supply a filename argument to MD2SKINI and have it simultaneously record a SKINI score file for future reuse.
- Modifications to <I>Object.h</I> for OS_TYPE compilation dependencies. <I>Makefile</I> automatically determines OS_TYPE when invoked (if you have the GNU makefile utilities installed on your system).
- A single distribution for all platforms. The Unix and Windows versions have been merged into a single set of classes. Makefiles and Visual C++ workspace/project files are provided for compiling.

/*! \page fundamentals STK Fundamentals
The Synthesis ToolKit is implemented in the C++ programming language. STK does not attempt to provide a new programming environment or paradigm but rather provides a set of objects that can be used within a normal C++ programming framework. Therefore, it is expected that users of STK will have some familiarity with C/C++ programming concepts. That said, the STK classes do have some particular idiosyncrasies that we will mention here. Starting with STK version 4.4, all STK classes except RtAudio and RtMidi are defined within the stk namespace.

<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).

STK currently runs with realtime support (audio and MIDI) on Linux, Macintosh OS X, and Windows computer platforms.

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).

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 create audio DSP and/or synthesis programs
- 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.).

\endcode
On WindowsXX and Unix platforms, the following operations are necessary to establish a socket connection between the Tcl/Tk GUI and the STK program:
<OL>
<LI>Open a DOS shell and start the STK program with the <I>-is</I> flag (ex. <I><B>demo Clarinet -or -is</B></I>).</LI>
<LI>Open the Tcl/Tk GUI (e.g. tcl/Physical.tcl) by double-clicking on it, or type <TT>wish < tcl/Physical.tcl</TT> in another DOS shell.</LI>
<LI>Establish the socket connection by selecting <I>Socket</I> under the Communications menu item in the Tcl/Tk GUI.</LI>
</OL>
Note that it is possible to specify a hostname when establishing the socket connection from the socket client. Thus, the STK socket server program and the Tcl/Tk GUI need not necessarily reside on the same computer.
\section midi Realtime MIDI Control Input:
On all supported realtime platforms, you can direct realtime MIDI input to the STK Clarinet by typing:
\code
stk-demo Clarinet -or -im
demo Clarinet -or -im
\endcode
This will attempt to use the default MIDI port for input. An optional MIDI port number can be specified after the <TT>-im</TT> flag. Valid MIDI ports are numbered from 0 (default) and higher. On Linux and Macintosh OS-X systems, it is possible to open a virtual MIDI input port (that other software applications can connect to) by specifying a port identifier of -1.
\section polyphony Polyphony:
The <I><B>stk-demo</B></I> program supports an arbitrary number of voices via the <TT>-n NUMBER</TT> command-line flag and argument. For example, you can play eight BeeThree instruments with realtime output and control them from a MIDI device by typing:
