Hallo, Kyle Klipowicz hat gesagt: // Kyle Klipowicz wrote: Frank, I'm curious about how you use list objects in composition. I'd love to see a little etude from you about that whenever you find the time. You always make such clear, concise, and fun instructional patches. That's flattering so I guess I should give an example. ;) [list] of course is useful for lots of stuff, e.g. as a general container for messages (it's central for sssad in this regard), to convert meta-messages to lists and back, etc. In composition list-operations let you encapsulate many common tasks in reusable abstractions. Johannes mentions LISP in his book, which is the mother of all list-based composition software, but you can do lots of stuff in Pd as well thanks to list. As an example attached are abstractions that do four transformations of little musical motives. The motives are stored as lists of numbers, where each number represents a scale step. In the example a major scale is used, but you can do 12-tone serialism as well and also apply the transformations to rhythm lists etc. The four operations demonstrated are: - retrograde: play a motive backwards. That's a simple [list-rev] from the [list]-abs (included) - transpose: add a number to each list-element. I used [list-map] here. - inversion: That's a bit more complicated. Quoting Wikipedia: Inverted melodies When applied to melodies, the inversion of a given melody is the melody turned upside-down. For instance, if the original melody has a rising major third (see interval), the inverted melody has a falling major third (or perhaps more likely, in tonal music, a falling minor third, or even some other falling interval). Similarly, in twelve-tone technique, the inversion of the tone row is the so-called prime series turned upside-down. http://en.wikipedia.org/wiki/Inversion_(music)#Inverted_melodies In inversion.pd this is realised by walking through the list with list-map, taking the difference between the current element and the previous element, then substracting this from the current element. The first element in a list is treated specially as it has no previous element (it's just copied). - retro-inversion: that's just a retrograde followed by an inversion. As we have abstractions for both not, just bundle them in another one. list-compose.pd show all four operations in use to transform a little motive.

Re: [PD] dynamic creation arguments for route
Hallo, also see [sroute] which is a hidden leftover in the [list]-abs collection. The idea is to use a one-argument [select] instead of [route]. [select] with no or one argument has an additional inlet, where you can set the thing it selects. Decorate this with some [list split 1] and [list] objects and you have a simple settable [route]. No dynamic patching or externals necessary. Ciao -- Frank Jonathan Wilkes hat gesagt: // Jonathan Wilkes wrote: I built a settable route abstraction using dynamic patching.

[PD] variance from mapping library
I'm not sure if it's a bug but: when using variance (from mapping library) - I get negative numbers. Since variance is supposed to be always positive and I don't see anything wrong in the way the abstraction is done, I presume there is something I'm missing.

Gladly, it is a different proposal, so johannes book, as well as Miller's and Floss Manuals all are complementary publications. Talking about Phase Vocoder is an attempt to make it more accessible than in Miller's book, in a sense that I wish to reach people with no Background in Computer Science. I dont emphasize much on programing and implementing things in Puredata, so books like johanes' are definately handy... I like the part on Convolution, as it is not covered in other pd books I guess.

One of the main reasonings behind Pd in pure:dyne is to package each library on its own, to avoid both the maintenance nightmares of a huge package build system and the tricky timing involved to get all externals working at once.

The first element in a list is treated specially as it has no previous element: it's just copied and used as the starting note. Frank and all, Attached is an inversion.pd which is a bit simpler -- usually when inverting in pitch (rather than pitch-class) it's easier/simpler/better to invert with respect to an axis of symmetry rather than with respect to the first pitch in the series (of course you can assign the first pitch as the axis). Meanwhile, if you're doing this with pitch-class instead of pitch (in other words transposing and inverting in a mod 12 universe, which is what you would probably be doing with 12-tone rows before assigning specific registers), instead of inverting with respect to an axis of symmetry, you invert with respect to the sum of the two pitch-classes in the original and inverted row -- sometimes called the index of inversion. The group theory is even cleaner if you think of transposition as an addition operator and inversion as a multiplication operator (in this case multiplication by 11, mod 12). If you're doing mod 12 operations, there is one more pitch operator -- multiplication by 5 or 7 -- which maps the chromatic scale to the circle of fifths and vice-versa. Then you can think of retrogression as order inversion, and rotation, the other standard order-position operator, as order transposition. If you think it would be useful I can put together the standard 12-tone operators in mod 12 (or for that matter, an assignable modulus), but of course specific register information disappears. A more interesting but more difficult project would be to write a list abstraction to output the set-class of a given set of pitches, with an assignable modulus.

Re: [PD] a simple counter, I'm not able to do it tonight
So you want a counter that counts to 100 and then begins at 0 (or 1) again? If I'm understanding correctly I would do the following: [bang( | [float]X[+ 1] | [select 100] | [0( the 0 message at the end could also be a 1 depending on if you want the counter to begin on 0 or 1, it is sent to the right inlet of float. the outlet of float is, in addition to [select], also sent wherever you want the counter to be output to. here is the same patch as a subpatch (keeping in mind that the 0 message still must be connected to the right inlet of float): [inlet] | [b] | [float]X[+ 1] | \ | [outlet] | [select 100] | [0( ...of course you can always use the [counter] object. [counter 100] will probably do the trick all by itself. and finally, if i'm understanding incorrectly and you wanted it to count up and back down, use the example that was posted previously with the absolute values and [wrap], or use [counter 100] with the up/down message sent to it, you'll have to check the help file for exactly what that message is... hope something in there helps. -Ben pd-list@iem.at ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Hallo Matt, Matt Barber hat gesagt: // Matt Barber wrote: Attached is an inversion.pd which is a bit simpler -- usually when inverting in pitch (rather than pitch-class) it's easier/simpler/better to invert with respect to an axis of symmetry rather than with respect to the first pitch in the series (of course you can assign the first pitch as the axis). Ah, that's much simpler indeed - and thanks a lot for your other explanations. I updated the code on http://footils.org/pkg/list-compose.tgz to include this as inversion-axis.pd and made the old inversion.pd a wrapper around this, which set the first note as the inversion axis. (I made a little change to save the multiplication by 2 by using [swap] and a loadbang.)

Re: [PD] dynamic creation arguments for route
Dynaroute does something different than sroute-- you can send a list to its right inlet to change any or all of the creation arguments. You could also simply change the word route to select in the guts of the abstraction and have a dynaselect, which might be handy for quickly setting key bindings. -Jonathan --- On Wed, 3/18/09, Frank Barknecht f...@footils.org wrote: From: Frank Barknecht f...@footils.org Subject: Re: [PD] dynamic creation arguments for route To: pd-list@iem.at Date: Wednesday, March 18, 2009, 9:27 AM Hallo, also see [sroute] which is a hidden leftover in the [list]-abs collection. The idea is to use a one-argument [select] instead of [route]. [select] with no or one argument has an additional inlet, where you can set the thing it selects. Decorate this with some [list split 1] and [list] objects and you have a simple settable [route]. No dynamic patching or externals necessary.

Re: [PD] pdp_rec
There is definitely some bug in it regardless of where it comes from.

A student and I just lost some time working on her non-trivial patch and the problem was that she was using the jpeg codec with pdp_rec~. We didn't have a lot of clues to work with to diagnose the problem. If we do not wish to remove the codec entirely, perhaps a warning might show up on the pd console that the jpeg codec is buggy/not supported. without having a full understanding of the problem, i somehow doubt that the problem is really in pdp/pidip but rather within libquicktime. putting a warning in the calling application might be even more confusing, once the codec get's fixed upstream. filtering for a certain codec can also be confusing, since the codec-names are dynamically extracted from what libquicktime offers, and thus can change by simply installing/upgrading a certain plugin. of course this doesn't help you with your problem. fga,sdr IOhannes -- ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Re: [PD] couldnt create pdp
The prognosis was meagative on my two recent fedora excursions, f8 and f10. Pd would work fine but most extended specific obects couldn't be created. I lost a lot of time figuring this out. Moved to ubuntu today. Much happier now. With this new tutorial manual there are a few total beginner things that I've learned the hard way that could be included. There is no reason not to consolidate info. Small links with basic info get lost in most scene/communities I find.
