First of all, I’m beyond stoked on how well Dorico now does notating and playing back microtonal music–it’s absolutely game changing for me and my personal creativity and output have skyrocketed. A critical addition for me was getting Noteperformer–ALL the instruments respond to non. vib markings and it sounds fantastic–most of my day got sucked into writing for full 18th century orchestra, never trying to write for one before in my life, because it sounds fantastic. I took the exceptionally tedious time to enter every accidental in the Sagittal Athenian set defined in 1200 tone equal division fo the octave, which is nearly a hundred accidental types, but to my surprise my workflow is still plenty fast and playback seems entirely accurate.
A bug I just noticed is that Dorico handles microtonal accidentals in transposing scores incorrectly. I decided to check out what performance scores of my admittedly very unlikely to get performed extremely microtonal work would look like, and it definitely resulted in pretty crazy accidentals for the Bb trumpet and F horn. For example, the first note in the horn is an unaccented G, but in the transposing score it displays as a Ebb minus a syntonic comma for whatever reason, which is almost but not quite the D it should’ve displayed as. They were all accidentals as defined by
I was curious to see if it was simply shifting transposing instruments down a fixed interval in 12EDO, but it seems like transposing instruments do play accurately. I set up a score in 13EDO with a clarinet and piano and had them play in unison and they were spot on. In a short section it seemed like Dorico was generating sane accidentals for the clarinet part when given the relatively few options of 13EDO.
