Re: [PD] list issue
thanks guys, i made a simple patch based on mathieus idea. (see attachment) i like to apply more control on listlength, without specifying it, like i would have to with [list-equalize]. now, depending on the devisor of 2, with my master-sequence of lets say 2000 (ms) i get lists with very small and very big values. for example: 15.625 1.95312 3.90625 1.95312 500 250 1000 31.25 62.5 7.8125 125 any ideas how to get smoother/smaller differences between the list-items? thanks. j #N canvas 437 216 195 346 10; #X obj -72 146 urn; #X obj -72 96 iter; #X obj -72 24 inlet; #X obj -72 173 pack 0 0; #X obj -72 293 outlet; #X msg 12 100 clear; #X obj -72 120 t b a; #X obj -72 61 t l l b; #X obj -72 259 zl group; #X obj 10 126 list length; #X obj -72 238 pipe; #X obj -72 216 unpack 0 0; #X obj -72 194 zl rev; #X connect 0 0 3 0; #X connect 1 0 6 0; #X connect 2 0 7 0; #X connect 3 0 12 0; #X connect 5 0 0 0; #X connect 6 0 0 0; #X connect 6 1 3 1; #X connect 7 0 1 0; #X connect 7 1 9 0; #X connect 7 2 5 0; #X connect 8 0 4 0; #X connect 9 0 0 1; #X connect 9 0 8 1; #X connect 10 0 8 0; #X connect 11 0 10 0; #X connect 11 1 10 1; #X connect 12 0 11 0; #N canvas 91 22 294 416 10; #X obj 35 0 loadbang; #X obj 111 27 bng 15 250 50 0 empty empty empty 17 7 0 10 -262144 -1 -1; #X obj 111 53 random 2; #X obj 179 243 t f f; #X obj 111 192 f; #X obj 111 279 list-extend; #X obj 77 307 list; #X text -31 137 master(ms); #X obj 77 337 shakeitt; #X obj 77 359 print that; #X obj -22 1 inlet; #X obj 111 1 inlet; #X obj 153 337 list-accum; #X floatatom 153 360 5 0 0 0 - - -; #X obj 111 74 route 0 1; #X obj 179 192 f; #X msg 35 139 2000; #X obj 111 96 t b b b; #X obj 179 214 / 2; #X msg -22 27 set \$1; #X text 14 359 slave(ms); #X connect 0 0 16 0; #X connect 1 0 2 0; #X connect 2 0 14 0; #X connect 3 0 5 0; #X connect 3 1 4 1; #X connect 3 1 15 1; #X connect 4 0 5 0; #X connect 5 0 6 1; #X connect 6 0 8 0; #X connect 6 0 12 0; #X connect 8 0 9 0; #X connect 10 0 19 0; #X connect 11 0 1 0; #X connect 12 0 13 0; #X connect 14 0 17 0; #X connect 14 1 15 0; #X connect 15 0 18 0; #X connect 16 0 15 1; #X connect 16 0 4 1; #X connect 17 0 16 0; #X connect 17 0 6 0; #X connect 17 1 5 1; #X connect 17 2 4 0; #X connect 18 0 3 0; #X connect 19 0 16 0; ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

For the network objects the lists are made of floats so the type restriction is not important. Right, but when it comes to making reusable classes, you have to choose between type-restricted statically-allocated, and freely-typed stack-allocated, and whatever class you make for processing lists doesn't work on arrays, and whatever class you make for processing arrays doesn't work on lists. Is there any way around that problem? Also a table can be reused and resized and its contents never get added to the symbol list so there's no constantly increasing memory involved. The symbol-table is a separate issue. You could make use of lists with mixed floats and symbols freely in lists and always reuse the same symbols, or you could be mixing floats and pointers. The typical web page has a huge amount of irrelevant text that would quickly clog the symbol table, so it's more efficient to extract the relevant bits before converting any of it to a symbol. I never ever mentioned converting a web page into a bunch of symbols. I'm concerned about the proliferation of list-operations and the duplication between list-operations and array-operations and how it will tend to inflate the number of classes and by default (if the design of classes just goes the usual way) the interfaces of those two sets of classes won't be synchronised with each other, so it will mean more documentation to make and especially more documentation to read.

Latency is mostly affected by the device driver for any source.

It reminds me, I once applied in music composition at UQÀM, but when they sent me a letter telling me they wanted to test my piano skills with sheet music, I didn't reply, because I don't have any piano skills and can't read sheet music in realtime.

But I've never seen this in one notational form or another. Independently of how it's written, I've never heard it either. You don't see that because composers generally don't hide quintuplets by adjusting the time signature. Put anything intended for human musicians into 5/4, for example, and then you must subdivide the measure-- 3+2, 2+3, etc.-- because that's the first thing a player will want to know/feel when reading it. So now each measure has some assymetrical subdivision. Then any anti-quintuplets would have to be shown as tuplets (e.g., 4 in the space of 5), which, even if there are fewer of them, would be unecessarily complex because common time is, well, common, symmetrical, and easier to subdivide. With quintuplets, there isn't (or at least ideally shouldn't be) an implicit hierarchy of beats within the quintuplet. I think that's why they are favored in late-Romantic piano music, like Scriabin's Prelude No. 1, Op. 15, to get a kind of floating, improvisatory quality in a melody against the underlying pulse. The anti-quintuplets here would be everything that's notated in the standard fashion. So, there is this asymmetry whereby you can find plenty of patterns of accretion of durations in multiples of 5, but not much splitting of durations in multiples of 5. You see plenty of examples of what Kyle Gann, in his Nancarrow biography, calls divisive rhythm-- dividing a measure up into groups of 5, 7, etc.-- in Schoenberg and many others. There was evidently a big divide between supporters of this procedure, and the additive procedure of Stravinsky et al of building asymmetrical rhythmic groups from a common small subdivision like the 16th-note. But for divisive rhythm, subdividing three or four levels deep quickly gets complicated and hard to read/conceptualize/perform/etc. Many of Stockhausen's early scores (ab)use this degree of complexity. He and others from the 50s evidently didn't find the need to stick strictly to one type of asymmetrical division, however-- there are triplets, nested in quintuplets, nested in whatever. But who knows, maybe there's some integral serialist pioneer out there who decided to break with convention and write a piece only using nested quintuplets. Henry Cowell divised a system of notation for things like fifth-notes in his book New Musical Resources from 1930. I think he actually used them in Quartet Romantic, though I haven't seen the score in a while. I'd be glad to get references to specific pieces that contain a lot of quintuplets. Of the five composers you named, I only heard Nancarrow, I only heard of Nancarrow, and then, I don't recall any quintuplets in it, but I didn't see the score and perhaps I couldn't grasp the rhythm of it just by ear (?). What is the nature of the rhythm you're trying to grasp by ear? If it's rhythm within a common pulse that divides strictly into subdivisions of fives (instead of twos), I don't think I know examples of any music that do that. But it's intriguing to think about some kind of dance music being written with this constraint. What I have heard are a) quintuplets to notate an independent tempo in a multi-tempo context: Elliott Carter's A Mirror in Which to Dwell b) quintuplets as obsessively/excessively written-out rubato: Ben Johnston's Sonata for Microtonal Piano and c) tempo ratios like 4/5/6 in Nancarrow's Study No. 49. There's also the music of Brian Ferneyhough, which I don't know as well as the others. But it's basically divisive rhythm in which long pulses are divided up into any number of large and small nested tuplets. In this case the large tuplets have the effect of changing the tempo within the larger pulse. I'm guessing if you took the patch that's part of this thread and periodically randomized the type of beat divisions, you'd end up with similar-sounding rhythms, with the restriction that any nested tuplet
