I don’t see anything here that should give Dorico any issues. Just make sure you don’t mix up the voices.
I’m not sure what you mean by what kind of effect.
There are many tutorials on the Dorico YouTube channel. I’d focus on note entry videos and anything to do with voices:
… and math.
Upstem treble clef: 48:64
Bass clef: 12:16
I haven’t figured out the inner voice on the treble clef yet but I’m sure it’s just a subdivision of 48:64
Hi @love, this is doable, but tricky because I think the melody voice is not mathematical correct, because of the double dot, and the need to overlap the last note of every beat automatically.
I was able to reproduce this using of course hidden tuplets. The lower voice in upper staff’s C automatic alignment is only achievable with the rhythms written as in the score, putting the C in the last note of the beat, but some rests remain, that have to be removed. And then you can beam as desired (“jumping” the removed rests).
Here the result and the Dorico file (if you click on the stems of the melody voice you will see the End Voice property, activated, used to remove the rests):
(notice: the playback of the melody will not play as expected because of the octave line influencing it. Now I am too tired to look for a correction to this…)
