I'm wondering if this phenomenon is possibly related to the MIDI issues I've 
been having with the Windows builds of Csound6? Could it explain why 
PortMIDI is seemingly affecting PortAudio (audio output), as described 
below?

I've had two problems, both of which involve PortMIDI and its apparent 
interference with PortAudio (all run from console):

1) Windows 7: PortMIDI doesn't make PortAudio crash, but it causes a minumum 
80 second delay in the printing of available PortAudio devices to the 
screen, thereby delaying performance by at least that amount of time. (I 
only recently discovered this wasn't an actual crash.)

2) Windows XP: PortMIDI disallows PortAudio completely (the listing of audio 
devices *never* appears on console output). The only remedy is to 
specify -+rtmidi=mme, which promptly lists the PortAudio devices and 
procedes to playback - but *makes multichannel output* impossible (only 
stereo functions).

So, just looking for a clue to what I've been experiencing. (My latest MIDI 
piece is quad.)

The symbol that need to be changed is ‘SendMessage’, if you rename all 
instances of it in that class to
say, SendMidiMessage, it should fix it.
