Tempo marks, etc.in parts extraction

This could possible be done, but is pretty tricky: extract that FL1+2 part twice, Name one Flute 1, the other Flute 2, then in FL1 make all voice 2 notes and rests invisble (and maybe silent) and in FL2 do the same foa all voice 1 notes and rests. In the next major version this should be simpler, thanks to a project of 2016 GSoC

MuseScore can currently only extract 1 line of music into 1 part, it cannot split it into 2 different parts, so the 2 flautists would have to read each part off of the same sheet in MS.

When I transcribe scores, I generally keep the format of the full score I am transcribing from. As long as the 2 lines of music do not cross, they generally are on a single line for music and not very difficult for a musician to read. When they start crossing, the score will have 2 lines of music for as many measures as needed. At that point I add a new line as in the score. The unfortunate side effect is that the line stays there empty when not needed in continuous view that I use to enter the score. When I switch the score to pages, I hide empty staffs so only pages with music show up on the score. I do the same with the parts, except I extract both flutes as "Flute 1 & 2" and adjust the line breaks to have multiple lines only when needed. I do something similar when an oboist doubles English Horn. Having transcribe several score it has become apparent that with practice, reading 2 parts off of 1 line would not be difficult. The printers take measures to make it as easy as possible to distinguish the two parts.

The "french" horn lines normally do not cross, because horn players specialize in low and high notes, so multiple lines for horns I & II are rare with the exception of mostly late romantic pieces where there are 8 horns total in the score and various numbers of horns are on a line in the full score. Mahler was terrible at this. Because of the enormity of such scores, I have not considered what I would do if I were asked to separate such a score into parts. The process is too slow in version 2.x that it would take a large amount of time to make each change. When 3.0 comes out the process should be much faster, so I'll probably look at it then if not asked to before then.

As far as what the musicians are used to seeing, the horn players are used to the 2 parts on a line for the above reasons. This is true of both classical and concert band music. I'm not sure what Flute and oboe players are used to since I have never seen a classical flute or oboe part printed individually. In concert band I saw both individual and combined parts for the flutes (individual lines seemed to be far more common) and never saw more than one oboe part.

In 3.0 there are going to be provisions to show multiple lines of music on one line in a score, so the flexibility will be greatly increased. I'm not sure of all the details for its implementation, mostly because no one knows for sure since the code is still being written. I'll wait until the file format is finalized before I start testing 3.0 like I did with 2.1. It's called unstable, but the files will always be able to be opened in any 2.x version of MS.

Realistically, while scores published before 1990 or so usually combined two flutes on one staff, scores since then are as likely as not to have separate staves, but most notation programs, like MuseScore, don't directly support the ability to generate separate parts if they are one one staff in the score. So its become quite common to have scores presented this way. Probably most conductors don't *like* this trend, but it it what it is. As mentioned, a future version of MuseScore should remove this limitation. Meanwhile, you'd have to do the parts manually - create two copies of the part, delete the notes of the other voice etc.

You even can't add a tempo text to a non-top staff
