Thanks for the response.

Sorry to say that it didn't work.

Just in case I goofed, here's what I did:
I set Pref -> General -> Initial Track Type to "MIDI". I closed, re-opened to start a new song, verified my change was still in effect and started a new song using the chord entry as before. Only my Real Drums track came through until opening the Mixer Window and pressing the "Default" button.
