  45         In order to compile a VST (TM) plugin with this architecture file
  46         you will need the proprietary VST SDK from Steinberg. Please check

  55  * VST-2.4 wrapper for the FAUST language.
  56  *
  57  * Usage: faust -a vst2p4.cpp myfaustprog.dsp
  58  *
  59  * By Julius Smith (http://ccrma.stanford.edu/~jos/), based on
  60  * vst.cpp by remy muller remy.muller@ircam.fr
  61  * http://www.smartelectronix.com/~mdsp/.
  62  * Essentially, vst.cpp was edited to look more like the "again"
  63  * programming sample that comes with the VST-2.4 SDK from Steinberg.
  64  *
  65  * NOTES:
  66  *  Relies on automatically generated slider GUI for VST plugins.
  67  *   - Horizontal and vertical sliders mapped to "vstSlider"
  68  *   - Numeric Entries similarly converted to "vstSlider"
  69  *   - No support for bar graphs or additional numeric and text displays
  70  *   - Tested on the Muse Receptor Pro 1.0, System Version 1.6.20070717,
  71  *     using Visual C++ 2008 Express Edition
  72  *     (part of the Microsoft Visual Studio 2008, Beta 2)
