IMPROVEMENT: Voices in Lilypond

[walterbender]

OK. I can clean up multiple voices somewhat. And I have newlines working in the output now... had to safe encode them.

I suspect that the {}s were from unused start blocks in your code. I can filter those out.

Eventually it would be good to detect the proper staff to generate... maybe you can come up with some logic for me?

[walterbender]

OK. I pushed a patch to better handle multiple voices. I struggled a bit because you were missing some {} in the example you gave above:
\new Staff \instrumentOne should be \new Staff {\instrumentOne}
But it turns out that including that generates extra empty staffs. Leaving it out and just defining the instruments seems to do what we want.

I am confused. Now Lilypond output is not working well for me.

It seems to be caused by two things, I think:

1. Lilypond doesn't seem to like the numbers in the title of the instrument
2. I think we need to following code at the bottom (you mention the brackets, I don't seem to need the brackets...):

>\<<
\new Staff \instrumentOne
\new Staff \instrumentTwo
\new Staff \instrumentThree
\new Staff \instrumentFour
>\>>

FWIW, in the meantime I am reaching out to some colleagues who are more familiar with Lilypond for their input. The syntax is super-useful, but a little esoteric and I don't think that I will really master it very quickly.

I think I have a reasonable solution at this point. If the turtle is named, the instrument takes on that name. If the turtle in unnamed, it uses a name off of a list of rodents.

Here is some sample output:

\version "2.18.2"
\header {
dedication = "Description: http://walterbender.github.io/musicblocks/"
title = "Title: My Music Blocks Creation"
subtitle = "Subtitle:"
instrument = "Instrument:"
composer = "Composer: Mr. Mouse"
arranger = "Arranger:"
copyright = "Copyright: Mr. Mouse (c) 2015 -- CC-SA-BY"
tagline = "Made from MB v. 328bc6d"
}

mouse = \new Staff {
g4 a4 b4 g4 g4 a4 b4 g4 b4 c'4 d'2 b4 c'4 d'2 d'8 e'8 d'8 c'8 b4 g4 d'8 e'8 d'8 c'8 b4 g4 g4 d4 g2 g4 d4 g2
}

brown_rat = \new Staff {
g'4 a'4 b'4 g'4 g'4 a'4 b'4 g'4 b'4 c''4 d''2 b'4 c''4 d''2 d''8 e''8 d''8 c''8 b'4 g'4 d''8 e''8 d''8 c''8 b'4 g'4 g'4 d'4 g'2 g'4 d'4 g'2
}

mole = \new Staff {
g''4 a''4 b''4 g''4 g''4 a''4 b''4 g''4 b''4 c'''4 d'''2 b''4 c'''4 d'''2 d'''8 e'''8 d'''8 c'''8 b''4 g''4 d'''8 e'''8 d'''8 c'''8 b''4 g''4 g''4 d''4 g''2 g''4 d''4 g''2
}

chipmunk = \new Staff {
g,4 a,4 b,4 g,4 g,4 a,4 b,4 g,4 b,4 c4 d2 b,4 c4 d2 d8 e8 d8 c8 b,4 g,4 d8 e8 d8 c8 b,4 g,4 g,4 d,4 g,2 g,4 d,4 g,2
}

{ <<
\mouse
\brown_rat
\mole
\chipmunk

}

Yes!

If the turtle in unnamed, it uses a name off of a list of rodents.

or turtles...

It might be better to stick with turtles, since our choir is really the "turtles". I want the user to really make the connection that the voices are the turtles (faster than it took me to make the connection).

Maybe Mr. Mouse represents the conducting/composing elements.

...so to bring Mr. Mouse into UI, I propose that the "play music slow" icon be changed to Mr. Mouse with his baton. And I want to change the opening picture to show the "turtle choir" with Mr. Mouse and some blocks in the "background". How does that sound for branding?

[walterbender]

All fun ideas. I was thinking we could use a mouse icon instead of the
turtle. But we need the artwork.

I thought of same thing, but am a little conflicted b/c of the history of the code (precedent is important). Also the current turtle says "forward" real well so far.

Lastly, I am trying not to create more work for everyone.

Not sure what is outstanding here. We have multiple voice support. We can create issues re artwork under a separate ticket.
