Import MIDI and split 4 parts into quartet

This must be a common problem but I can’t seem to find it here, so sorry if this has been asked and answered.

I am trying to import the midi of a public domain song. It imports fine as four parts in one violin part. I would like to separate it into the four voices of a string quartet (like Sibelius’ “explode” feature). I already have an empty string quartet in my flow, but this violin is separate from them, and I can’t tell if it’s a new flow (I imagine it is as it starts at measure 1).

Can anyone tell me how to separate out the four parts. The song is consistently in four parts, so there are no messy bits where there are 3 or 5.

Thanks,
Chet

Step 1:
Go to Setup mode (Cmd-1 or Ctrl-1).
In the Flows pane at the bottom locate and select (by clicking on) the flow that contains your imported MIDI. Now, with your flow selected, look to the Players pane, top left. Add your string quartet players by ticking the boxes next to each of them.

Now go to Write mode (Cmd-2 or Ctrl-2) and find your imported MIDI.

Step 2:
Select the first bar of the imported MIDI by clicking anywhere in the space between notes.
Bring your mouse pointer up to the very top of the screen until the menus appear (they’ll already be showing if you’re not in full screen mode).
Click Edit, then Select To End Of Flow. The whole of that stave should now be highlighted.
Click Edit again, then go into Filter, Notes in Chords, Top Note or Single Notes.
Then use Cmd-X or Ctrl-X to cut these notes.
Select the first bar of the Violin 1 stave.
Use Cmd-V or Ctrl-V to paste these notes.

Step 3:
Repeat Step 2 twice to fill the Violin 2 and Viola staves.
The Cello part will be quicker as you won’t need to filter (given you’ll only have the cello line left once you’ve filtered and cut the top three notes of each chord).

In future I’m sure Dorico will have comprehensive explode/reduce features, but I’m sure it’s taken me considerably longer to type this post than it’ll actually take you to complete the steps.

Enjoy!

THANK YOU very much! :smiley:

Please enjoy this crude explode script for string quintet. I wrote it out of necessity, and I hope somebody will benefit from it:

Please note that it deals with one selected chord at a time, and the chord must have 5 notes, piano track should be the last one, and string quintet should be just on top of it.
One can edit the script for a quartet for sure.
