I am trying to engrave a transposed song. It's written without key signature but is very tonal. It starts in C and ends in C#. I want to transpose it down a minor third. The part in C is fine, but the part in C# ends up as A## and there are far too many double-sharps for it to be performable.
I found the 'minimal accidental' snippet but that looks as if it messes up the tonality - a mixture of A sharp and B flat.
I tried the code below, which get the note names right but the octaves go completely wrong. Is this a bug? It would be a useful feature if it could be corrected.
\version "2.22.0"
\language "english"
{
\transpose c a,
\relative {
c'4 d e f g a b c
\transpose as bf
{cs, ds es fs gs as bs cs}
}
}

Peter
