I have just tried this, and it’s going to be great fun to use! However, in 4.0.0.1026 the numbers-only engine appears to be malfunctioning. Whatever numbers I type seem to get a 4 appended to them: If I type 1234 or 1.2.3.4, Dorico proposes to add 14 flutes, 24 oboes, 34 clarinets, and 44 bassoons.
Separate to this (and what prompted me to try it) is a small error in the Version History PDF: On page 38, in the paragraph with the 2picc.2.2.1 / 4.3.3.1 example, the clarinets and oboes are mentioned in the wrong order. It should be oboes before clarinets (and indeed the software does it right).
