There’s this cool parameter “Node” in Dorico, but so far it never does anything.
For many harmonics there are alternative positions that sometimes make performances easier.
See this useful list:
For example, the 7th harmonic at “tritone” position.
In such cases, I still have to resort to notating the harmonic manually as diamond notes.
Another nice thing would be microtonal indications for some of the farer harmonics, which currently are displayed as the same (increasingly wrong) stop position, however the playback is correct.
