When my app calls MIDIClientCreate(),
the function takes about 10-15 seconds to return.

The interesting thing is when i launch AudioMIDISetup,
the same delay seems to happen when it is loading the
MIDI Devices pane.

BUT if i keep AudioMIDISetup open and then launch my app,
the call to MIDIClientCreate() returns immediately.

I have uninstalled all audio and MIDI device drivers thinking it
might a problem there.

Any idea why this is happening?

The first app that invokes CoreMIDI causes the MIDIServer process to launch. This can takes time, partially proportionate to how many drivers are installed.

If you launch an additional client, it doesn't have to wait for the server to launch.
