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