Transposing playback

Hi.

I have tried adjusting the Edit instruments dialogue, but I am not getting the results I want.

I want the playback to sound one octave lower than written on bass sax. At the moment it is playing one octave too high.

Can you help?

Thanks

Dorico provides three bass sax instruments. All of them use the treble clef for transposed layouts and sound two octaves plus a major second lower than written (which I think is standard). One of them uses the treble clef for concert layouts, at pitch; one uses the treble clef sounding two octaves lower; and one uses bass clef (at pitch).

If you want a bass sax that sounds only one octave lower than written, which of these instruments are you starting with? And do you want it sounding one octave lower than written in concert layouts or transposed layouts?
