Hallo, João Pais hat gesagt: // João Pais wrote:
Depening on what kind of polyphonic patch you want to do, there are some newer alteratives to nqpoly4.
If you want to polyphonize a simple midi instrument that accepts
pitch/velocity pairs with [makenote] syntax, I'd recommend u_makepoly from the rj
library. To polyphonize oneshot instruments like drums, use u_robinpoly or
u_robinpolymono.All three come with extensive help files.
ah, I didn't say that. basically there are simple synth patches (with
audio, all output for a main [throw~]) that take in lists with parameters. the lists come from a "score" of data structures arrays (for now up to 6 parameters/arrays), at a rate of 100 a second. so I guess no midi or oneshot type events. anyway I'll look at your suggestions.
I guess, you could use u_robinpoly then. The difference is in the voice allocation algorithm: u_makepoly uses the one from [poly] that relies on makenote-like lists as parameters.
But u_robinpoly just has a counter that counts modulo the number of voices (i.e. round-.robin polyphony). Every list you sent to robinpoly will be sent to the next free voice unaltered (well, it will become a list-message, but you can also directly send pointers for example). There is no effort whatsoever to free voices, and as soon as all voices are taken, the first one will be reused.
unrelated: since you mentioned the rj library, I think it might be
interesting (at least for me) to pack that library in pd-extended. does
this makes sense/is practicable for you guys?
The rj-library is a moving target and gets new objects almost every week.
Of course it's free software, so it could go into pd-extended, but I tend to think of "rj" as something I came to call "dirlib" (i.e. the opposite of "libdir").
Because it is (almost) fully pd-vanilla, you can use it in a novel (or very old) way: as a drop-in library that you just copy to whatever project directory you are currently working on. (With RjDj this would be a Scene.) So a "dirlib" is a library living in project directories. Just add [declare -path rj] to your main pd file and that's it: you have a small, but at the same time very powerful and fully documented musician's library right at your fingertips.
[list]-abs is another example of such a "dirlib" you can use by copy-installing it and adding a declare-ation. But as rj contains a minimal list-abs subset this is only necessary in special cases.
The advantage of the dirlib approach is, that this project directory will continue to run on every Pd vanilla installation without any dependencies outside of your project directory (with two tiny exceptions).
So even if a later version of rj changes substantially, your old project with the copy of rj *inside* continues to work as it always did. (As long as Pd doesn't change too much, of course.)
