Hello Nick, Transposing an E (concert pitch) for a Bb instrument should always produce an F#, since the interval E-F# is a major second, like the interval Bb-C. If you prefer the E to transpose to a Gb you can use \transpose ais c' \new Staff \jjfStaffAA since the interval E-Gb is a diminished third, like A#-C. However, that will probably lead to lots of nasty double-flats for the rest of your music. I tried a small example, and (using LilyPond 2.11.34) I always get an F#, both with and without a key signature. Perhaps you could post some of your code that produces a Gb? -- Groeten, Alard.
