PortMedia Code

Added Pm_CreateVirtualInput and Pm_CreateVirtualOutput for macOS. Need to implement for ALSA.

It turns out the recently updated portmidi.sln has absolute paths that will not work on other machines. This is a "feature" of CMake, so the right thing to do now is start with Cmake and CMakeLists.txt, and build a solution file. The portmidi.sln file has been removed from the repo.

updated portmidi.sln using cmake. This portmidi.sln seems to work correctly using MS Visual Studio Community 2015.

Modified fast with -n option to send expired timestamps, minor fixes there too.

Created new test: fast.c sends a lot of messages.

fixed CMakeLists for Ubuntu -- not sure why the old version worked; maybe CMake has changed.

Set the svn:EOL property to native.

Updated pmwinmm.c for x64 architectures.
Updated README_WIN.txt with some additional hints.
Removed some old commented-out sysex buffer code.
portmidi.sln is updated to MS VS Express 2013, but you can build a new solution file with CMake.

Compiled on Windows 7 using VC 2010.

Added patch from RJ Ryan to fix bug involving multiple devices. Also integrated a few things from Audacity.
