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)
