谢谢. When you write about two different things (octaves and tempo), please make two different tickets, so it's easier to do one at a time, thanks :)
Yes I think we should do tempo, but I don't think it should be a single global that does not change, because Lilypond nowadays can change tempo at any time during the music. You can do it with LP:
commands:
WithStaff
LP: \tempo 4 = 96
:LP
1 2 3 4
LP: \tempo 4 = 84
:LP
5 6 7 1'
but this will look wrong on the jianpu staff. Before adding a command, I need to know what the output should look like. Should it just say "4 = 84" in text above the second bar? Or is it more complicated than that? Is there an example of published jianpu music that changes tempo half way through that I can look at to check what it looks like? Thanks.
I'm not a professional musician, and I'm not sure what it should look like. Maybe it's similar to 5-line staff. Almost all the jianpu I've seen has a fixed tempo. Thank you for letting me know the usage of "LP::LP", that is enough for me :D
A player in our local Chinese orchestra (CUCOS) has now sent me a scan of some jianpu music with a metronome-mark change in it, and they just used the Western symbol for it (♩=76). That means we can pass the Lilypond command through without change (unless perhaps we want to reduce the size of the symbol a bit), and the rest is just a matter of making the syntax a bit easier.

But I think it should be like this:(written in the ly file:![2021-10-02 09-33-43 的屏幕截图](https://user-images.githubusercontent.com/45248671/135699763-d9a15236-a8bd-4ecb-a7a4-778a22f1d9cc.png)
{ <c' e' g'> <c' c''> <c' d''> <c' e''> }
)And the midi file is also wrong.
By the way, I saw here that someone added the speed setting by a global variable "tempoValue". I think this is helpful for your "TODO". Hope you can add this to your code, thanks!
