Imported PDF, now want to see 4 voices as generic treble instruments
I've imported a PDF score that has Piano and 4 voices (see attached screenshot). Then I cut&pasted them into a String Quartet template. The original score had performance flexibility in mind, and gave the instruments names of "Treb 1", "Treb 2", etc. Instrument names and clefs naturally got changed in the pasting operation.
Now I'd like to see the 4 voices as just generic voices, each on a separate treble staff, so that at a later point I can pick some or all parts and transpose them for the instruments and musicians available.
I've read https://musescore.org/en/node/15803 but could still use some advice.
Also, the original score had each voice doubled in octaves, probably to give even more playing flexibility. Is there an easy way to delete one of the octave lines without deleting each note head?
