[list]-abs
by Frank Barknecht 02 Nov '05

02 Nov '05

Hi, I collected my [list] abstractions into attached archive. None of these abstractions require any externals, but of course they need pd-0.39 at least. Currently the most recent version always is to be found in my pwd~ at http://royalrabbit.goto10.org/svn/goto10/pd-patches/fbar/list-abs/ but later I will check these into CVS as well. (Btw: Does anyone have a decent script to sync svn and CVS?) They don't have a proper license, as they are so simple, consider them public domain or released under the Pd license. Here's the README: list-abs -------- These are abstractions implementing common list operations. Included are in alphabetical order: last-x.pd get a list containing the last x atoms received. list-demux.pd route lists to different outlets (like demux in zexy). list-drip.pd serialize a list automatically (like drip in zexy). list-drip2.pd serialize two lists in sync as long as first list lasts. list-dripslow.pd serialize a list on demand: each bang will output the next element. list-makefilename.pd apply [makefilename] on list elements, if they are symbols. list-math.pd apply [expr OP] with OP in (+,-,*,/) on list elements, if they are floats. list-rev.pd reverse a list. list-rot.pd rotate a list (move X elements from front to back) sroute.pd a settable [route] object for a single selector. take-two.pd take a list as input and print all combinations of length two without repetition. triple-scale.pd this actually is not using [list]: Interpolate between two (x,y,z)-points. Have fun, ignore externals. Ciao -- Frank Barknecht _ ______footils.org_ __goto10.org__

RFC: "list split" abstraction for negative indices
by Frank Barknecht 02 Nov '05

02 Nov '05

Hi, I want to include an abstraction into [list]-abs which acts as a wrapper around [list split] but also accepts negative indices to split off a list from the back. That is, a "list 0 1 2 3 4" splitted at index "-2" would give two lists, "0 1 2" and "3 4". While this is no problem to implement, I'm still undecided about, how I should order the outlets of this abstractions? To recapitulate: Currently the standard [list split 2] would send "0 1" to the first outlet and "2 3 4" to the second. Should a fictional [list split -2] send "3 4" to the first or to the second outlet? (Note: I tend to prefer sendign "3 4" to the first outlet, as it's technically easier, but I would like your opinions, too.) Ciao -- Frank Barknecht _ ______footils.org_ __goto10.org__

peakit~ (was binline~) v0.1
by Ed Kelly 02 Nov '05

02 Nov '05

Hi guys, As promised, the peakit~ external (thanks to mr zmoelnig for the memset tip _) is now part of the cvs repository. It's a bit shaky, but seems to work. Please let me know if you find any bugs (or even better, if you fix any bugs!!!) Also get listmoses - the two externs are meant to go together.

CarnivorePE and Pure Data
by Owen Cartwright 02 Nov '05

02 Nov '05

hello list, I was wondering if anyone has attempted, or knows of anyone who has made a CarnivorePE client (http://rhizome.org/carnivore/) using PD? I have done very much googling and list searching but with no luck... The patch seems simple enough: CarnivorePE sends out its data on port localhost 6667, so in PD a 'netreceive' object with this same port should receive the data, correct? But it does not. I am not very familiar with networking in pd, or how the 'netreceive' and 'netsend' objects function specifically, and I can't seem to figure out to make the patch work. Any and all help or information would be greatly appreciated. many many thanks, owen cartwright p.s. telneting to port 6667 works (prints carnivore's data to the screen), can't pd do this too?

something like this ....
by Matthew Williams 01 Nov '05

01 Nov '05

how difficult would it be to build something like this in pd: http://illformed.org/glitch/?page=docs#intro I'm still going over tutorials but it seems to me like it wouldn't be to hard... Maybe not as diverse and with less bells and whistles. and of couse it wouldn't look as "cool". But i'd like to get to a point where i could create stuff like this. The "rockafella" patch in the tutorials is a good example. Something where you define buffer sizes and play them back at different speeds ... or randomly. From what i understand i could do this by randomizing the tableread object, or whatever object reads the buffer audio. Also it's be nice to reverse different chunks, loop snippets of buffer audio, delay, gate, flange, shuffle etc.. And ofcouse all this would need to be done in real time, and control parameters via midi. Also it'd be nice to do this sort of thing to midi sequences , although audio seems like it's a little easier to manipulate so i guess i should start there.

vline_exp~ external (?) + poll
by federico 01 Nov '05

01 Nov '05

vline~ is really good for building signal envelopes. however it is not possible to generate logaritmic/exponential ramps. does actually exists an external that does it? ? ... btw, i made a patch (mainly for practice with pure-data) which does this, but it does statically in an array (it seems there aren't exp~/log~ too) so it is not very handy. [*] if you want see, get the patch at http://xaero.ath.cx/cms/144.html and launch it. use both vsliders on the right do define start and end value of the ramp, and both hradios (the smaller ones) to select a portion of the array, hit draw! and you have just rendered a piece of ramp. use the function_param slider to see what i need ;) i think a "signal shaper patch" patch (that i could write in the next hours) would do the dirty job....the use a look-up table and pre-calculate the function does part of the job. but would be nice to have the ability to do: | 1, 0 500 0 log 0.7, 1 1500 500 exp 1.3, 0 250 2000 ( | [vline~] bang! :O which of these option would be better? a) write that patch, use the classic vline and 10+ signal shapers? b) write a brand-new external (this implies some study of signal(tilde) externals c) hack the vline~ object does someone is interested in this "project"? ciao! -- Federico [*] a note about this patch: the patch uses some quite usual concepts related to sequence editing, such as selecting ranges, and selecting value pairs. maybe do exist some more appropriate objects to interface the user with?

max msp vs pd
by Matthew Williams 01 Nov '05

01 Nov '05

Ok i'm curious .... why would someone spend 400 dollars on max when you can get pd for free. Is it because of the ability to make plugin's using pluggo. But can't you make plug-ins from pd as well. I was going to buy max but i came across pd and thought, "this is great..max for free." Am i wrong. And yes i read about the differences .. but they don't justify 400 dollars. wondering, matt

[list]-abs now also in CVS
by Frank Barknecht 01 Nov '05

01 Nov '05

Hallo, the [list]-abs collection of abstractions using [list] from pd-0.39 to do various list operations is now in CVS at http://pure-data.sf.net as well, directory "abstractions/footils/list-abs". Proper help files for all abstractions are included. There are some new additions, so here's the updated README: list-abs -------- These are abstractions implementing common list operations. Included are in alphabetical order: last-x.pd get a list containing the last x atoms received. list-accum.pd sum all floats in a list. list-demux.pd route lists to different outlets (like demux in zexy). Not an abstraction, just a patch illustrating the idiom. list-drip.pd serialize a list automatically (like drip in zexy). list-drip2.pd serialize two lists in sync as long as first list lasts. list-dripslow.pd serialize a list on demand: each bang will output the next element. list-inter.pd element-wise linear interpolation between two (float) lists. list-inter-example-gem.pd shows a more complicated usage example, but requires gem for visualisation. list-len.pd calculate length of a list. list-makefilename.pd apply [makefilename] on list elements, if they are symbols. list-math.pd apply [expr OP] with OP in (+,-,*,/) on list elements, if they are floats. list-minmax.pd find minimum and maximum float in a list. list-rev.pd reverse a list. list-rot.pd rotate a list (move X elements from front to back) sroute.pd a settable [route] object for a single selector. take-two.pd take a list as input and print all combinations of length two without repetition. triple-scale.pd this actually is not using [list]: Interpolate between two (x,y,z)-points. Also see [list-inter], which is more powerful. Have fun. Ciao -- Frank Barknecht _ ______footils.org_ __goto10.org__

ascseq reverse
by timon 01 Nov '05

01 Nov '05

Hi, I just found the [ascseq] object. Working with type in GEM this makes loading text and writing out to the text objects a dream. I found the object in references without much description. Im wondering if there is a reverse object, one that takes a list of decimal number and converts it to its referenced character. Like [ixprint] without the print feature. Any clues? thanks, Timon.
