;******************************************** midi "under the hood" *********************************************
/*
This part is meant to take care of the "under the hood" midi input and output selection and save selection to an ini file.
Hopefully it simplifies usage for others out here trying to do things with midi and ahk.
* use it as an include.
The code here was taken/modified from the work by TomB/Lazslo on Midi Output
http://www.autohotkey.com/forum/viewtopic.php?t=18711&highlight=midi+output
Orbik's Midi input thread
http://www.autohotkey.com/forum/topic30715.html
This method does NOT use the midi_in.dll, it makes direct calls to the winmm.dll
Many different people took part in the creation of this file.
