tape-like transport emulation (search for external)
by errordeveloper＠gmail.com 20 Jun '08

hello list! i got back to pd after a little break ;) i had made a few recording which i had been trying to master in Snd, but Snd has weired set of options which i like ..but sometimes it's really unstreightforward ;( so .. basically i just came with an idea of a mastering suit, i mean a set of abstraction which would have quite similar approach as you do have in recording studio! first thing i need right now is a mixdown patch, which is nearly ready; i wnna mix 4chan -> stereo. the panning and amplification are implemented (well, in a weired way, but i like it that way). the concept is to do all in pd, cause i couldn't get jackd running and just don't want it really. i'm sure pd is capable for doing most of what i need and this is a proof-of-concept project actually ;) so i wish to do some editing in Snd and the do live-mode mixdown iside pd. i have got it working quite ok with [readsf~], but it takes only play and stop control commands ;[ *IDEALY*, i'd wish to have tape-like transport with timecode and all other imaginable features, .. but actually the timecode and marking ..etc could be implemented externaly with basic objects ;) i really need some external which could rewind and fastforward with the sound like tape makes ..surely that will be fun for others as well! i couldn't find anything really .. can quite imagine the way of doing it with [soundfiler] and a set of tables ..but i reckon that isn't quite right in case of 4 or 6 channel files up to 10min (oor even longer). again, surely many people are gonna suggest to use jackd and jamin, but as i have just said - i'm traying to implement a pure data mastering suit ;] does anybody know an external which would do that kind of thing? cheers, -- ilya .д

Someone want to port this to GEM?
by vade 20 Jun '08

20 Jun '08

Hello I just released a plugin for Quartz Composer with source. It provides a bit of a hackish way to move textures from one 'VJ' (god I hate that term) app, to another. Basically, its glorified screen capture, but it stays on the GPU. You can use it to 'sample' a texture from anything on screen. http://002.vade.info/ Its *very* fast because it does no readback. On my system I am able to capture full res 1440x900 (my whole screen) at a solid 60fps. Perhaps a GEM dev could port it - I'd attempt it, but I imagine someone could quite easily do this.. It could be very useful to the communities to have a method to move video to and fro from GEM to other environments and back. (although, its hardly an ideal method). Ive used it to move Processing output, Jitter output, GEM output to Quartz Composer sans issue. You have my blessings to port it, share on, and Peace.

I'd like to help, but I am not going to have time. I'll be on tour starting Sat. for two months. Any flext people want to try to get flext builds in Pd-extended? There could also be a Pd-devel-extended without too much work.

Gem, make small snapshots while display original size?
by Martin . 19 Jun '08

19 Jun '08

Hi, in Gem, Im trying to resize a video to take _small_ preview like snapshots that i can save as files (with pix_write), but still sending a stream with the _original size_ to another place, to either display or record. So far it seems that [pix_resize] deals with resolution of the video while [rectangle] actually sizes it. And here is the point where i probably haven't understood gem enough (being a bit impatient maybe..:) can i resize what i play with a [rectangle] while not displaying it, while displaying another [rectangle] playing the same feed? Or is there a smart way about this? Cheers, Martin

Guys, thanks for all the effort you've put into this project. I found this community inspiring, and sometimes it makes me think that yes, we as a species can still get along together despite our many differences.

Lorenz attractor
by James Dunn 19 Jun '08

19 Jun '08

Hi, I've recently been studying Lorenz attractors and other chaos circuits and have built one in PD. (I've looked at Ben Bogart's external containing a Lorenz attractor but I wanted to build my own). The patch is detailed below and I'd appreciate any comments regarding any aspect of it, but in particular, I'd like to know: 1) What is a better method of displaying the output? (the lines always get erased as the array draws new lines) 2) Why does it take 2 bangs to start it? (I previously had an initial x value of 0, but it refused to start at all, although it seemed to be working at one stage!) many thanks James #N canvas 530 323 643 475 10; #X text 398 60 dx/dt = S(y-x); #X text 398 75 dy/dt = Rx-y-xz; #X text 398 90 dz/dt = xy-Bz; #X text 398 37 Lorenz's original equations:; #X floatatom 108 191 5 0 0 0 - - -; #X floatatom 178 191 5 0 0 0 - - -; #X floatatom 249 191 5 0 0 0 - - -; #X obj 164 37 bng 15 250 50 0 empty empty empty 17 7 0 10 -262144 -1 -1; #X msg 192 87 10; #X msg 220 87 28; #X msg 249 87 2.66667; #X text 398 120 S=10 \, R=28 \, B=8/3=2.66667; #X obj 108 142 expr $f4*($f2-$f1) \; ($f5*$f1)-$f2-($f1*$f3) \; ($f1*$f2)-($f6*$f3) ; #X obj 108 275 f; #X obj 136 275 +; #X obj 108 232 t b f; #X obj 86 109 r x; #X obj 108 253 delay 5; #X obj 114 109 r y; #X obj 178 232 t b f; #X obj 178 253 delay 5; #X obj 178 275 f; #X obj 206 275 +; #X obj 136 297 s x; #X obj 206 297 s y; #X obj 249 232 t b f; #X obj 249 253 delay 5; #X obj 249 275 f; #X obj 277 275 +; #X obj 277 296 s z; #X obj 143 109 r z; #N canvas 0 0 450 300 (subpatch) 0; #X array array1 100 float 2; #X coords 0 100 100 -100 200 200 1; #X restore 372 212 graph; #X obj 174 387 tabwrite array1; #X obj 108 210 / 200; #X obj 178 210 / 200; #X obj 249 210 / 200; #X msg 51 211 stop; #X text 191 35 start; #X obj 76 156 bng 15 250 50 0 empty empty empty 0 -6 0 10 -262144 -1 -1; #X text 31 155 resume; #X obj 261 367 * 2; #X obj 174 367 * 3; #X obj 174 346 - 30; #X obj 261 346 + 26; #X msg 108 87 6; #X msg 164 87 0; #X msg 136 87 1; #X connect 4 0 33 0; #X connect 5 0 34 0; #X connect 6 0 35 0; #X connect 7 0 44 0; #X connect 7 0 46 0; #X connect 7 0 45 0; #X connect 7 0 8 0; #X connect 7 0 9 0; #X connect 7 0 10 0; #X connect 8 0 12 3; #X connect 9 0 12 4; #X connect 10 0 12 5; #X connect 12 0 4 0; #X connect 12 1 5 0; #X connect 12 2 6 0; #X connect 13 0 14 0; #X connect 14 0 23 0; #X connect 14 0 13 1; #X connect 14 0 43 0; #X connect 15 0 17 0; #X connect 15 1 14 1; #X connect 16 0 12 0; #X connect 17 0 13 0; #X connect 18 0 12 1; #X connect 19 0 20 0; #X connect 19 1 22 1; #X connect 20 0 21 0; #X connect 21 0 22 0; #X connect 22 0 24 0; #X connect 22 0 21 1; #X connect 25 0 26 0; #X connect 25 1 28 1; #X connect 26 0 27 0; #X connect 27 0 28 0; #X connect 28 0 29 0; #X connect 28 0 27 1; #X connect 28 0 42 0; #X connect 30 0 12 2; #X connect 33 0 15 0; #X connect 34 0 19 0; #X connect 35 0 25 0; #X connect 36 0 17 0; #X connect 38 0 17 0; #X connect 40 0 32 1; #X connect 41 0 32 0; #X connect 42 0 41 0; #X connect 43 0 40 0; #X connect 44 0 12 0; #X connect 45 0 12 2; #X connect 46 0 12 1;

PdSVN 0.8
by Luke Iannini 19 Jun '08

19 Jun '08

Hi all, Here is a new version of [pdsvn]. I shrunk this one down to be as small as possible so that it can serve as a "status-badge" in your patch. Clicking on the badge lets you perform adds, diffs and commits as appropriate. This version is for individual patches. I have another abstraction for directories of patches in development (it's in SVN as [pdsvndir] but it's still pretty early). A modified [getpatchname] is still required; Jamie, do you think you could take a look at my patch to consider including it (it's in the zipfile below) so this can Just Work? I'd be happy to check in the change but I don't want to rustle around in your directories uninvited :). I'm including a binary of it for Mac/Intel, so I guess you'll need that to try this unless you feel like recompiling [getpatchname] with my tweak. Cheers Luke
