Is it possible to have a section ending with the Segno sign, then a “coda” representing a second part and ending with a “D.C. al Segno”, manually edited to add a “poi Coda”, followed by another “coda” and having all this play back correctly?
So, played A B A C with written A(segno) B(DC al S poi Coda) C.
Real life example: Tchaikovsky The Seasons ‘December’
I’m reproducing Tchaikovsky’s notation. There is a Segno sign at the end of Part 1, then there is Part 2 (Trio), then Part 1 is repeated and, at the end of that part one jumps to Part 3 (Coda). Proofreading is giving me all sorts of errors so it is clear that I am doing something wrong.
Yes, to understand reapeat structures (and have correct playback), Dorico needs them to be “standardized”. There are many options regarding how Dorico should render those components, but if you want something totally different (say, havein a Signo where normally would be a Coda), you have to do some switcherydoodle.
