I am trying to export a score as both MusicXML and MIDI. I see no Export option for either. Am I missing something? If not, has that changed in v4? Do I have any workaround options?

Thanks so much.

Musicxml Import/Export is only part of ver. 4.0

to be clear, MusicXML export and MIDI export are both part of v4.0 FOR WINDOWS? I'd like to be certain about this, in considering an upgrade. many thanks!

Yes, they are.

related potential production issue:
I am guessing that OpusMOdus can trigger Record Start/Stop in Ableton Live 10?
Is that true, and does that require adding a code block for that purpose?
I also want to be as assured of this capability before upgrading.
Many thanks for you help here!

You can't trigger Ableton record/start/stop from OM, but this can be done.

thanks so much for getting back to me. how then can it be done? if i need to be asking this question elsewhere, i completely understand!

and one more question re: exporting MusicXML and MIDI files: does Opusmodus v4.0 embed identical tempo and bar-offset info in both exports???

The export file is equal what you see in the Notation display.
