PortMidi does list internal midi devices on OS X. You can use "Audio
MIDI Setup.app" (probably in /Applications/Utilities) to view devices
and create "soft ports" using the IAC Driver. My Audio MIDI Setup.app
appears to show every device that has been plugged in at one time or
another (these appear faded out), but PortMidi only tells you about
devices that are active. The PmDefaults application lets you save
preferences -- if the preferred device is available when PortMidi is
initialized, it can be located using Pm_GetDefaultInputDeviceID() or
Pm_GetDefaultOutputDeviceID().
I often use SiimpleSynth.app with PortMidi. SimpleSynth can listen to
either an IAC port or it can listen to its own SimpleSynth port. This
has to match the device selected by PortMidi for messages to get through.

Hi,
is portmidi supposed to be able to list internal midi devices on OSX?
So should people be able to open an internal midi device and make
beeps out of it? Or is there something that needs to be started
before that works?
