100 a couple of the header files in Steinberg's ASIO SDK, and it'd be easy to copy
101 about 30 lines of code into this cpp file to create a fully stand-alone ASIO
102 implementation...
103
104 ..unfortunately that would break Steinberg's license agreement for use of
105 their SDK, so I'm not allowed to do this.
106
107 This means that anyone who wants to use JUCE's ASIO abilities will have to:
108
109 1) Agree to Steinberg's licensing terms and download the ASIO SDK
110 (see http://www.steinberg.net/en/company/developers.html).
111
112 2) Enable this code with a global definition #define JUCE_ASIO 1.
113
114 3) Make sure that your header search path contains the iasiodrv.h file that
115 comes with the SDK. (Only about a handful of the SDK header files are actually
116 needed - so to simplify things, you could just copy these into your JUCE directory).
