Hi Craig. Thanks for the reply. Sorry to be so long getting back to you, but my Internet has been down for a few days.
As per your instructions, I have a Multi assigned to my Roland Juno D keyboard in the Env, created a new audio Instrument track, clicked on it (right-clicking had the same apparent effect as left clicking), and selected MIDI Instrmnts (my layer designation, right?) I don't have a MULTI option but I do have the name of the Multi instrument assigned to my synth, so I chose that.
1st question: Don't the preceding steps simply change the audio instrument track I started with to an external MIDI instrument track? If so, why start with an audio instrument?
OK. Next I have my MIDI instrument set up for the track and I hear the Roland's sound, and MIDI data in the transport window.
Recorded some MIDI stuff. Happy enough.
Clicked FILE. Only export option is Export selection as MIDI file.
No audio file option.
In the local Audio menu there is an item Convert Regions to Audio File, but clicking it didn't seem to have an effect. If an Audio File was created, I can't find it.
With all the stuff Logic Express can do, surely recording external MIDI instruments in a mixdown for use on a CD wasn't reserved just for Pro users. That's be like leaving the output jacks off a synth for economy purposes.
