Scheme function to change the MIDI port of a note inside Lilypond?

It would prove incredibly useful to be able to change the MIDI port of a specific note, possibly using scheme code. Lots of other things can be done via MIDI using scheme functions inside Lilypond -- for example, changing tempo, etc. So guessing it's possible to use a simple scheme function to

It's easy to show that Kieren is being deceptive with his example. Here's how he did it: Kieren used a Lilypond function to suppress printing of the actual tuplet number, then used another Lilypond function to substitute a text string with no connection to the actual tuplet number instead of the

Re: Solution to 7 over sqr(71) time against integer polyrhythms

It's pretty clear from the nature of the bugs that there was some internal rational integer calculation limit in lilypond. What's baffling is the way it's dealt with internally in lilypond. The procedure seems to be to do everything in 32 bit integers and then throw an error if that limit gets

Nice try, but so obvious I already tried it long ago -- remove the timing translator and default barline engraver from the Score portion of the layout and insert it in the Staff portion. Nope. Doesn't work with my score. By all means, keep spending all your time and energy attacking people who

Re: Solution to 7 over sqr(71) time against integer polyrhythms

My statement that Lilypond does not allow barlines to be inserted wherever you want on individual staves without drawing barlines through all the other staves is factually accurate. Inserting \bar "|" in one staff draws lines through all the other staffs. There is no way to prevent this. It's a

Another example I posted a while back and no one was able or knowledgeable enough to help me with, so once again I figured it out mostly on my own, with a hint from Trevor Baca. This example is a simple set of hypermeasures formed by broken tuplets. The hypermeasures on the top two and middle two

Solution to 7 over sqr(71) time against integer polyrhythms

The solution (thanks to a hint by Trevor Baca) turns out to involve setting a bunch of overrides at the start of the Lilypond code, setting proportional spacing and a standard make-moment setting (usually 1/20 or 2/20 works well), specifying the score size so that the notes don't get scrunched up

Re: How to get irrational tuplets inside a regular meter like 9/8

Whatever Lilypond is doing internally, there's some arbitrary limit to the numbers it uses. Time signatures above some large value cause a crash. Too many tuplets of too many different kinds causes Lilypond to crash. There's no reason for that. None whatever. A competent programmer would not

This example eschews numbers for the irrational tuplets in favor of Greek letters, or at least the Greek names for the symbols. I'm not sure how to get a Greek font in Lilypond. It might not be possible. In any case it's not important, since that can always be fixed in the mix with photoshop. e

Three different types of Nancarrowesque acceleration notated

For the sake of completeness, here are all three types of acceleration used by Conlon Nancarrow. Here they're notated exactly, while Nancarrow typically punched holes in a player piano roll to get his accelerations. These aren't exactly the same as Nancarrow's acceleration, because he used

How to get irrational tuplets inside a regular meter like 9/8

An alternative method involves simply adding in the required rests, rather than squishing or stretching the entire measure with a large tuplet. Since this method is easy to calculate exactly because you're just adding and subtracting various integer fractions, it always produces guaranteed

Re: Mystery empty staves appear on score

Thanks, it's useful to know that Lilypond doesn't have printable objects to represent time values shorter than 1/128 note, but that Lilypond nevertheless does insert them into scores and deal with them. This offers an example of the inadequacy of the Lilypond documentation. This kind of

Re: Mystery empty staves appear on score

Thanks! That answer a lot of questions. So presumably the S2 is means "silent half note rest." I'm guessing, then, that S1024 or S4096 will generate silent 1/1024 note rest and silent 1/4096 note rests, respectively. Ideally, what I want is a silent rest of zero length. Experience shows that

How to get a polymeter with time signature 89888449/5199909 against 742739/45045

Lilypond crashes with the familiar error code if we enter those time signatures directly. But there is a workaround, and it involves approximating both meters with smaller rational fractions, then deleting the actual meter used and engraving the real time signature by hand on both staves. Then we

Two different time signatures with different tuplets in 'em

The logical extension of that example I posted with the large time signature, 4918233/340340, involves two different simultaneous measures with different tuplets and different time signatures, one large, the other not. In this case, the 4918233/340340 measure (which is really a different smaller

Re: compound time signature with non duple denominator

Well, the 3's indicate 3:2 broken tuplets. There seems to be some controversy over whether Tobin Chodos really wanted a single 3:2 eighth note at the end of every measure. If he does, then the 3's are correct. If he doesn't, then the question was unclear and we're answering something that wasn't

David remarked: >"One triplet eighth note" defines a duration of time (which the OP > appeared to get wrong in any case). One note cannot form a triplet. Sure it can. They're called broken tuplets, and lots of composers use 'em. Michael Gordon uses broken tuplets all the time. So does Mikel

Re: Can't get page breaks for 7 over square root of 71 meter

Hans; You mentioned: "LilyPond doesn't require all the barlines to align in order to be able to break a line, it only requires an arbitrary *moment* to align. If you have such a moment you can break lines, and the manual tells you how to achieve that." Sorry, no, the Lilypond manual does _not_

Re: compound time signature with non duple denominator

Yes, Thomas Ades and Brian Ferneyhough and Kyle Gann and many others have written music in non-binary meters like 7/6 and 21/10 and so on. This is hardly unusual nowadays. In fact, these kinds of meters go all the way back to Henry Cowell's "New Musical Resources," written in 1930, though Cowell

Re: compound time signature with non duple denominator

"Wouldn't that rather be (4 + 2/3)/4?" Yes, I think you're right. 1/3 is presumably half of the value of a triplet quarter note, so 1 triplet eighth note. I've corrected that in my second Lilypond example. My bad. Change the "6" denominator in my new Lilypond code to a 3 to get the meter to

Re: compound time signature with non duple denominator

Tobin Chodos mentioned: "That is, the measure is four quarter notes long plus one triplet eighth note." Oops. Unless I'm mistaken, 4 + 1 triplet eighth note would be 4 + 1/6, not 4 + 1/3. My Lilypond code was based on the assumption that you had 4 quarter notes + 1 triplet quarter note. Here's

..But apparently Lilypond page breaks don't work at all for an irrational meter like 7/sqr(71). I'm baffled. Why do page breaks work for 7/5 but not for 7/sqr(71)? The basic metric pulse is non-binary in both cases, so why should it make any difference whether the basic metric pulse is 5 equal

Can't get page breaks for 7 over square root of 71 meter

A meter of 7/sqr(71) simply means that that there are 7 eighth notes each of which has duration of square root of 71 = 1/8.426149 of a whole note, whereas a standard eighth note has duration of 1/8 of a whole note. Therefore each eighth note in 7/sqr(71) meter has a duration of 8.426149/8 =

I have an even more diabolical question, related to the one at the start of this thread. But let me first answer the original question, which was: "Is there a way to implement a non-binary time signature like 4 + 1/3?" I think I know a way to do this. This seems like an entirely valid question.
