I’m transcribing some music for the 7 string gamba (range from AA on the bottom string) from a hard to read facsimile in order to have something to learn the music from. Notation wise everything is okay, but I notice that anything below C is not played back (and it’s marked in red as an “impossible note”). I assume that means the bass gamba is represented as a 6-string bass starting at the D one fourth above AA, which is sometimes detuned to C in order to cover a cello part.
So my request is that you modify the instrument’s range down to AA or to add a 7-string version of the instrument that starts at AA. FYI, the lowest string of the 7 string gamba is never tuned differently (that I know of)
