The filter notes by pitch feature is very useful for correcting the awkward enharmonic spellings that Dorico produces in parts. Like the OP, I have an atonal piece with a baritone sax part, and the resulting part needs a lot of these corrections. I hope the Dorico team will revisit enharmonic spelling after transposition (both for parts, for alt/arrow keys, or transposition popup) to make this less labor intensive. I imagine that enharmonic spelling for tonal music is an especially tough problem to automate in a way that scales, but atonal music should be a lot easier. It would be great if Dorico would merely avoid double flats/sharps, Cb/Fb/E#/B#, and optimize the rest to minimize diminished and augmented intervals. This isn’t quite what Elaine Gould would prefer, but the result would require far fewer corrections than that provided by the current transposition/spelling algorithm.
