  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).
