Question:
The MIDI documentation tends to suggest that one requires a MIDI source (file or descriptor) in order to play MIDI.
Is it possible to play a note without a MIDI resource?

Answer:
Call PlayNoteL() directly after creating the CMidiClientUtility.
There is no need to open a source resource using OpenXxxL()

eg

CMidiClientUtility* midi=CMidiClientUtility::NewL(*this);
CleanupStack::PushL(midi);
TTimeIntervalMicroSeconds duration(1000000);
midi->PlayNoteL(1, 60, duration, 64, 64) //play middle C on channel 1 for 1 second at average velocity.
CleanupStack::PopAndDestroy();
