• A MIDI interface to use MIDI input controls. (NOTE: This may be built into the soundcard on your computer.)
• Tcl/Tk version 8.0 or higher to use the simple Tcl/Tk GUIs provided with the STK distribution (available free over the WWW for all supported realtime platforms).

Linux (specific):

• A soundcard to use realtime audio input/output capabilities. In order to use the effects project, the soundcard and drivers must support full duplex mode.
• OSS or ALSA device drivers for realtime sound output and MIDI input.

Macintosh OS X (specific):

• A C++ compiler does not ship by default with OS X. It is necessary to download the Developer Kit from the Apple WWW site in order to compile STK.
• The internal Macintosh audio hardware typically supports a sample rate of 44100 Hz only. Therefore, it is necessary to either specify this rate as a command-line option to the STK example programs or to change the default sample rate inside the Stk.h file before compilation. In addition, the RT_BUFFER_SIZE, specified in Stk.h, could be increased (to a higher power of two) for more robust performance.
• The tcl/tk interpreter does not ship by default with OS X, but must be downloaded from the internet. Binary distributions exist but it is instead recommended that you download recent tcl and tk source distributions (http://dev.scriptics.com/software/tcltk/downloadnow84.tml) and compile them as follows:

  make -C tcl/macosx deploy
  make -C tk/macosx deploy
  sudo make -C tcl/macosx install-deploy
  sudo make -C tk/macosx install-deploy
  

  (Note: the tcl and tk directories specified in the above lines will more likely be appended with version numbers) The default installation will place a link to the wish interpretor at /usr/bin/wish. The latest 8.4.1 release of tcl/tk has been tested on a 10.2 system and found to work correctly. In particular, redirection of a tcl/tk script to the interpreter (e.g., wish < test.tcl) works normally (which is not the case with binary distributions tested thus far).

  Initial tests have shown somewhat poor response between changes made in the tcl/tk script and the resulting audio updates. Also, it is not recommended to connect by socket from a tcl/tk script to an STK program because the tcl/tk interpreter does not appear to properly close the socket connection, leaving the STK program in a "hung" state.

Windows95/98/2000/XP (specific):

• A soundcard to use realtime audio input/output capabilities. In order to use the effects project, the soundcard and drivers must support full duplex mode.
• DirectX 5.0 (or higher) runtime libraries to use the precompiled binaries.
• Visual C++ 6.0 for compiling (though a precompiled distribution is available).
• For compiling the source (if not already in your system):
  • dsound.h header file (DirectX 6.1) - put somewhere in your header search path
  • dsound.lib library file (DirectX 6.1) - put somewhere in your library search path

WindowsNT (specific):

• DirectX support for NT is inadequate, so it is not possible to use STK under WindowsNT with realtime DirectX support. It may be possible to use STK under WindowsNT with realtime ASIO support, though this has not been tested.
