Trill line with accidental
In page 86 of the User's manual, considering "Extended ornament lines", we find that:
To add an accidental to an extended ornament, such as a trill line, select the line and double-click a symbol from the Accidentals palette.
By doing so, we get the symbol of the accidental over the e.g. trill line, and that's O.K.
Yet, the accidental is not really played-back. If we have a trill of "do-re-do-re-do-re" with a flat (♭) above it, we still hear a natural re (♮).
Is there something we can do about this?
