[Media_api] Brief PortMidi Question

[Adam Somers]

Hello,

I am developing Windows software with PortMidi and have run into a
problem I do not understand.

I am trying to use PortMidi to take Midi input on multiple ports.  The
problem is that the non-reentrant winmm_in_callback seems to get
called concurrently for each open port receiving simultaneous input
data.  That callback contains an entry count and brings down the app
(with assert(fasle)) when reentrance is detected.

Can someone tell me why this is happening?

Was PortMidi designed to handle simultaneous input on multiple ports?

Is there anything specific I must do to make this work?
