Hi MusicMan,
No, this "filter", i.e. the check boxes with the various parameter groups in the Memory window, only apply when memorizing Registrations. When changing OTS, ALL parameters that can be memorized in OTS are always memorized.
By the way, the parameters memorized in OTS (much fewer than can be memorized in Registrations) can be found in the Data List (chapter "Parameter Chart") of your keyboard model.
Best regards,
Chris
