From code poetry to interpretive PD poetry reading
by Pall Thayer 13 May '14

13 May '14

Hi All, For a while now, I've been writing short perl scripts as works of art. Somehow, this practice of mine has become associated with poetry, which was never my intention at all. Here's a new direction I'm experimenting with, interpretive poetry reading via PD... (requires the ratts external: http://kaskade.dwds.de/~moocow/mirror/projects/pd/). Title: Becumming Cummings -- ***************************** Pall Thayer artist http://pallthayer.dyndns.org *****************************

-batch option
by Oli Larkin 12 May '14

12 May '14

Hi, I'm experimenting with the -batch option. I would like to be able to process wave files and they should end up exactly the same length in terms of samples as the original file. Here is a test patch which writes a ramp which should last 44100 samples. I am launching it like this: /Applications/Pd-0.45-4.app/Contents/Resources/bin/pd -batch -nomidi -send "file test" /Users/oli/batchtest.pd The resulting file is 44096 samples long. I realise this is because the message rate delay which stops the recording is quantized to block boundaries (64*689 = 44096) Is there any way i can stop the recording after exactly 44100 samples have elapsed? thanks oli //batchtest.pd #N canvas 696 426 450 300 10; #X obj 194 157 writesf~; #X msg 189 107 start; #X obj 218 30 loadbang; #X msg 114 198 stop; #X obj 293 34 bng 15 250 50 0 empty empty empty 17 7 0 10 -262144 -1 -1; #X msg 250 111 open /Users/oli/test.wav; #X msg 292 66 \; pd dsp 1; #X obj 215 60 t b b b b; #X obj 74 159 t b b; #X msg 50 218 \; pd xquit; #X obj 86 51 phasor~ 1; #X obj 74 128 delay 1000; #X obj 285 191 receive file; #X obj 285 230 print file; #X connect 1 0 0 0; #X connect 2 0 7 0; #X connect 3 0 0 0; #X connect 4 0 7 0; #X connect 5 0 0 0; #X connect 7 0 11 0; #X connect 7 1 1 0; #X connect 7 2 5 0; #X connect 7 3 6 0; #X connect 8 0 9 0; #X connect 8 1 3 0; #X connect 10 0 0 0; #X connect 11 0 8 0; #X connect 12 0 13 0;

[PD-announce] pd-list mail-server: iem.at -> lists.iem.at
by IEM - network operating center (IOhannes m zmoelnig) 12 May '14

12 May '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 hi fellow patchers! as some of you might have already noticed, the mailserver of the pd-related mailinglists has changed from *iem.at* to *lists.iem.at* this has two implications: - - emails *to* the pd-lists should use *(a)lists.iem.at* from now on. e.g. please use <mailto:pd-list@lists.iem.at> in the future. - - emails *from* the pd-lists will use @lists.iem.at in their various headers, including the List-ID header. those of you who use mail-header to sort pd-related emails into various folders, will have to adjust their filters. the following lists are affected: - - gem-dev(a)lists.iem.at - - pd-announce(a)lists.iem.at - - pd-cvs(a)lists.iem.at - - pd-dev(a)lists.iem.at - - pd-list(a)lists.iem.at - - pd-ot(a)lists.iem.at - - pdweb(a)lists.iem.at the change has become necessary due to upstream decisions of the university's IT department, and is not to be questioned by yours sincerely. we don't have a time-frame yet when the old @iem.at adresses will stop working, but we don't expect it to happen soon. otoh, it is rather certain that the change /will/ happen at some point in the future, so let's be prepared. before the old email-adresses will cease to exist, you will be warned again (most likely with an automated reply for each email directed at the old adress over a prolonged period). in any case: please update your adressbooks to use the @lists.iem.at adresses from now on. fmadsr IOhannes PS: until recently it was possible to use e.g. pd-list(a)iem.kug.ac.at; the entire @iem.kug.ac.at domain has been disabled a few weeks ago, and can no longer been used. PPS: many years ago there used to pd-list(a)iem.mhsg.ac.at which has not been usable for longer than many can remember. - -- IEM - network operation center mailto:noc@iem.at -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 Comment: Using GnuPG with Icedove - http://www.enigmail.net/ iQIcBAEBCAAGBQJTcLnOAAoJELZQGcR/ejb4utYP/3sjUMSyPAEaeRDTk62trqrb tfx6auWMsngdKvwQgXC9Srk0vGRYKDaC3OCOzfiYNSLA11PwobcnnuE1EkQGlg0A Oh1uFH0Oegz17DvkjSkqy8hj1l55MT1imr3Q4/d68ghoyCXZsf65KFGP2aKk6/N3 lySzXGdD3qMJNq2ybo3p5HrL/7dhbR/9BAXd7c0rPrHH3Ifw4vCHd0C2YTEWhyvi J29slS0sVBfB56atjFPfPaQ7v/CSDVnoOk+OzrfjtWWf1zn2iQq4IrSQz8DYXQua 1xX6cB1Li2V6WADTA54qHF3uJ+PE9ISZY22ysJxCRsehNi+ERl7hH9E56+UbUyRa e7xtAXPFkJDtn7ekxWAqGc2WxhA4bhuUmBz1GyJRJERbObv79E/pabG91qdZx7MW ERNhMTHko1Ap8WOWcrcrDL0lZC+Q64aF4kov6oaHibM1I/N5tp50hQ5C+FXlr4DQ xGqRTkKhJYTDEwjQ3bt8QtCwhR9FhoH0E59AeVAFTOo4JDgRz9agb2J2+sSoX3wU 5tXG7wyyEzTwQyYdtGW3fX9rg6xiFshJIIYZIbMvIlrxRZDyPejXtUIfBWOe47Fq OD6pqcjcks4BKEjvjl7Q1RwbX75FuX0Esh7BBBG+9OeS5OGc6UT+5u2hgU9FdANL HDp9XAS9H0w+3PZVVORg =yDn3 -----END PGP SIGNATURE----- _______________________________________________ Pd-announce mailing list Pd-announce(a)lists.iem.at http://lists.puredata.info/listinfo/pd-announce

best format for send/receive between iOS and libPD
by i go bananas 12 May '14

12 May '14

I've got a six voice synth, each with about 20 variable parameters, and then sequence data, etc... and all of this data is being stored by the objective C front-end of my app. can someone tell me, hopefully from experience, what the best format is to send a lot of pattern data between obj C and libPD ??? should i package all the data as one huge list, or break it all into individual variables, or is it ok to organize it into groups for ease of management. my plan was to send messages like this from obj C: to [r instr1_pattern_data] : [vol 0.8, pan 0.5, pitch 0.75, param1 0.99 ... etc] actually, i'm not the one doing the C coding, i'm, just doing the pd side, but i have to prepare things on my end to make it flow as well as possible. Overall, i think there about 1400 values that need to be passed for every pattern, so it probably does need to be as well streamlined as possible. cheers for any help Matt

Installing PD on OpenSUSE
by Andrew Faraday 12 May '14

12 May '14

Hi All I've been trying to install pd-extended on OpenSUSE but whatever I do `make install` fails. It looks like it's trying to find pdlua_stack_dump but it's not defined... you can see the tail end of my make process here: https://gist.github.com/AJFaraday/2ee07be60ac7af5f7a6c If anyone knows why this isn't compiling I'd be grateful Regards Andrew Faraday P.S. If I can't figure this out I'm probably going to re-install this box with ubuntu again.

recursive controls problem
by plutek infinity 10 May '14

10 May '14

greetings! i'm sure this is a simple problem, but i can't seem to come up with the solution... i'm trying to control one numerical value in a few ways: 1. have a bang to set an initial value 2. have a slider for mouse control 3. use keyboard keys to increment and decrement the attached patch all works, except i ALSO want the slider position to pick up the current value, as changed by any of the other methods. the problem is, of course, that if i connect the expr result back up to the slider input, i get a loop with "stack overflow" errors. i'd be most grateful for any pointers you can offer... thanks much! cheers! .pltk.

more sprites!
by Jonathan Wilkes 09 May '14

09 May '14

Hi list, Here's another data structure sprite example: http://www.jonathanwilkes.net/sprite.webm I changed the object name and interface a little bit-- now sprites can have affine transformations. It's neat to use the "transform" method to see how few objects it takes to animate the sprite across the screen. Under the hood, the transform method should also be more efficient-- instead of vis'ing and unvis'ing the scalar, it just sends updated attribute to the image. Does anyone know if there's a standard sprite sheet format? Some sprite sheets divide up the sections into perfectly equal parts-- others look like they just spread them out arbitrarily through a png or gif. Atm I just take a directory as an arg and slurp up an image sequence. (And use imagemagick to split up the sprite sheet.) Best, Jonathan

convolution using pd-vanilla
by Oli Larkin 09 May '14

09 May '14

hi, is anyone aware of an example of both a brute force time domain (e.g. buffir~ in Max) and an FFT-based fast convolution patch in pd-vanilla? I would like to do a comparison of the two. Can be using a small IR, just for demo purposes. cheers, Oli

comparing symbols in external
by Jaime E Oliver 03 May '14

03 May '14

Hi all, I am trying to compare two symbols, one incoming in a list into an external and the other one stored internally in the external. It compiles fine, but I don't get a match. c code is below. Ideas on what I'm missing? J void testtext_input(t_testtext *x, t_symbol *selector, int argcount, t_atom *argvec) { int i; const t_symbol *storedsymbol = gensym("mysymbol"); for (i = 0; i < argcount; i++) { if (argvec[i].a_type == A_SYMBOL) { if ( argvec[i].a_w.w_symbol->s_name == storedsymbol) post("found match!"); } }
