Same notes, an octave apart. Why?

These two highlighted notes sound an octave apart. I have failed to ascertain why.

Are those two notes played by different instruments? If not, are you using a a transposing expression map for one of them?

Yes they are played all by the same instrument. There is only a solo guitar in this.

I guess we will need a bit more information - best would be (a stripped down version of) the file itself, of course.

I can send the whole file. Any reason not to?

When you add a bass guitar player in Setup Mode, Dorico automatically assigns Transpose up 1 octave expression map to it.

It is possible that you changed the expression map of one of the bass guitars to Default in the Play Mode:

That would result in one of the bass guitars playing an octave higher than the other.

Test - 2 flows Bach BWV 1007 Cello Suite 1 in G.dorico (1.1 MB)

Here are two flows with different octaves.

When you switch to Full score layout, you can see that those notes are indeed an octave apart:

I have no idea why they appear to be the same notes in the “Classical Guitar” layout.

OK, guitar is a transposing instrument.

Octave-transposing instruments include the piccolo (sounding an octave above written), glockenspiel (sounding two octaves above written), and guitar and double bass (both sounding an octave below written).

Full score uses concert pitch, so we see that selected notes are actually an octave apart. When we switch to Nylon Guitar part, everything is transposed because part layouts use transposed pitch by default.

“Allemande” flow is transposed 1 octave down as expected. However, “Courante” flow is transposed 2 octaves down instead. That’s the reason why selected notes appear to be the same in the Nylon Guitar layout, but sound an octave apart. I just don’t know yet why is everythng transposed 2 octaves down in the second flow instead of 1.

I figured it out. Bass clef in your second flow has Show for transposition option turned on for Transposing Pitch with Octave shift set to 1.

If you turn that off, you get notes correctly shown in the “Nylon Guitar” layout.

I see. 7-string Electric Guitar is convenient for this project because it supports 7 strings easily and makes a sound that isn’t distracting. Bass clef is appropriate for the same reason as is the cello, Bach’s original choice for this piece. I suppose I could have used cello, but it would sound funny and make it hard to think about plucking strings. If Dorico could accommodate our Brazilian friends some day, we would all be enjoying the real 7-string classical guitars that the Brazilians use. (The Russians too.)
Thank you for pointing out what is happening on the Full score. It never occurred to me to notice that. I’m not sure what it all means.
