Thanks for your reply, Bill.

That is what I want to accomplish; sorry if my message was unclear.
Here's what I'm doing now:
1. calling MIDIClientCreate() to create a new MIDI client
2. calling MIDISourceCreate() to create a new "source" endpoint,
owned by the client I just created. This shows up as a source in apps
like MIDI Monitor and SynthTest.
3. calling MusicSequenceSetMIDIEndpoint() to set the endpoint of my
MusicSequence to the endpoint I just created.
If I send noteon/noteoff messages to the MIDISource, they will pass
through to SynthTest, MIDI Monitor, or whatever, but the notes in the
playing sequence won't. (If, however, I set up the MusicSequence to
output to an AUGraph, I get sound.) My code ("test.m", although it's
mostly C-classic) is attached, in case that helps. I'm really at a
loss to what's going wrong.
You weren't suggesting that I create an output with
MIDIDestinationCreate, were you?

That is a good feature request; perhaps it is fortunate that I was
unclear. :-) I'll write it up.
best,
