Not all bass clef notes are the same?
I have to enter a piano part by hand. That's laborious. To make it easier, I added a bass clef staff below the piano staff, to enter the lowest long notes in the left hand piano part. In the "instruments" window, I wasn't sure what to call it, so I chose "contrabass." I renamed it to "piano" and set the instrument voice to piano. I noticed that notes on this staff sound an octave lower than they do in the bass clef piano staff. Yet the contrabass staff and the piano staff have the same kind of bass clef.
To make it work right, I switched the bass clef to "bass clef 8ve alta," in other words, the bass clef with the little 8 above it, indicating the notes in that staff are an octave higher than written.
I don't know if this is a bug. More likely a feature, but I'm curious. What is going on here?
