Yes, Jeffrey, I'm sorry. It was indeed my ritardando marking not slowing the tempo down. I notice you put a different tempo indication on the measure after the rit. indication. I wasn't aware we had do this. I will try it.
Well, this works, but only because I inserted the Adagio after the rit. indication. But "a tempo" doesn't bring it back to original tempo. You have to bring back the "Allegro" or whatever marking. I have had success in the past, not always of course, making the speed slow gradually without inserting Adagio and Allegro to return to original speed. Is there a way to have "rit." and "a tempo" behave properly without posting actual tempo changes in the score?
The "a tempo" should revert to the tempo that precedes the molto rit. Where does that original tempo appear in relation to this section I can see? And was that initial tempo created by an expression or is the tempo initially setup in the playback window?
FWIW, when I use molto rit followed by a tempo, it works.
