How can I apply an octave transposition that affects playback but keeps the written pitch unchanged?
For example, as is commonly done with guitar or double bass (electric bass) transpositions.
I don’t think it’s necessary to transpose anything, as long as you have selected guitar as the instrument in setup mode. It already sounds in the correct octave, as is usual for guitar.
As @Armin_der_Zweite says, Dorico instruments are already set up for the most usual situations.
You can check the transposition settings in Library>Instruments
I think I didn’t explain myself clearly. What I meant is this: the chosen instrument is piano, so Dorico plays the bass clef at written pitch. What I want is for the playback to sound an octave lower, while keeping the written pitch unchanged.
Actually, I’ve solved the issue (which only concerned the first eight bars), as you can see in the attached file. If needed, I could make the 8va symbol invisible.
So, problem solved!
But I’d like to ask another question:
In piano writing, is it possible to change the playback sound only for the left hand? That is, to have the right hand play with a piano sound and the left hand with a bass sound?
Thanks again for your support and your always helpful answers.

Yes, you can do this by enabling Independent Voice Playback in Play mode. This will create a separate channel for upper and lower staff and you can choose whichever sound you want for each.
