My basic Steinway is doing the strangest thing: any text expression that contains the word "only" triggers play of a D natural, 2 octaves down from middle C.
Obviously, this is some sort of strange Keyswitch effect.
Except I cannot, for the life of me, find ANY HP technique that has the word "Only" as a trigger, nor one that has the D natural two octaves down from middle C as the Keyswitch note.
My issue came about with the text expression (not intended to trigger ANY playback effect): "(for rehearsal only)".
If I change the text to read "(for rehearsal)", it works fine, but adding the word "only" causes this annoying staccato D to play.
