getting the name/receive symbol of a patch/subpatch
by Hans-Christoph Steiner 13 Jul '06

13 Jul '06

Does anyone know a way to get the name of a patch or subpatch from within Pd? Basically I want to dynamically get the name that you would use like this: [; pd-myobject.pd( The actual filename would work too. It seems to me that this should be part of a standard, message-based querying mechanism which could also be used for patch meta data like local namespace, current dir, etc. .hc ------------------------------------------------------------------------ If you are not part of the solution, you are part of the problem. - Eldridge Cleaver

datastruct: moving the position off a object
by moritz 12 Jul '06

12 Jul '06

[ola< | [list] i'm going trough the docs about datastructure, but i dont have a solution yet to move the position with the mouse, of a polygon without going in edit-mode.(i have also checked franks structsequenzer, there the rectangles can also only be moved in edit-mode). So, i want to have a simpel rectangle where i can move it (with mouse) the position, the "size" of it, without going in edit-mode... is it possible? [moritz< | [thanx] | [list]

I dream of a polyphony object with the dynamic-subpatch-creating advantages of nqpoly4, combined with the capacity to match up note-offs with previous note-ons, which is necessary for live (i.e., indeterminate duration) polyphonic music. Such a beast could be called "vgpoly", for "very good polyphony". :-) This more robust nqpoly4 object you've made makes improvement and extension a little easier to contemplate -- thanks, Frank. Once I have a little more PD experience under my belt, maybe I'll give "vgpoly" a try. Phil Stone

Processor load never goes above 60% at 900 oscillators, but it starts to get noisy above that. Maybe there's some arbitrary threading limit around 900? I'm curious what results non-OS X systems produce. I'll check it on the Windows side of this laptop tomorrow if I get a chance. Nice sound, especially using note numbers in the 20's. Phil

If so it seems like >it would be the perfect way, for its speed... it's just 'normal' ip, so everything that works over an ip network, also works over an ip-over-fw network (but only point-2-point) it's around 4 times as fast as 100mbit ethernet, but slower than 1gbit, so nowadays it isn't really of much use anymore when 1gbit is built-in in most new comps and the cards are cheap. sven.

data-s with math inside (feature request?)
by João Miguel Pais 11 Jul '06

11 Jul '06

Hello, I'm working on a struct where I use the variable aa to calculate something, and the variable bb [bb == aa - 1] to display it (due to screen display). If I edit one of them with mouse-dragging is there a way to update the other one directly, besides building a get aa -> set bb circuit on the side (which has to be constantly triggered with a metro)? I can't remember anything. I think it would be good to have also these internal math applications on data-s, and / or a way to make some variables dynamically (and directly) linked with each other, so that they can be updated with no delays or other kind of external triggering (this is actually connected with my request a few days ago about a mouse-click detector for data-s. I think it would be a great improvement in terms of usability). Joao -- Lugostr. 14 79100 Freiburg i. Br.

Re: [PD] converting decimal to binary
by adam armfield 11 Jul '06

11 Jul '06

<pre>thanks chaps, chuck, yeah, i'd been thinking with this one to use the larger numbers as is (instead of chopping them to 8 beat length), so that the original part loops every 8 beat, and part 4 for instance, is much longer... i've had some success with using prime numbers as the lengths for sequences, i got the tip from a flash book years ago, with animation it works well with several elements looping at the same time, it creates longer sequences that don't repeat the same way twice... at least not for a long time in sound terms i like using clock dividers set to prime amounts, then feeding both signals into a logic gate, with a bit of care this can make really nice rhythms (using several such units) the bitwise gates in pd don't really lend themselves to this, but more straightforward gates do... i've had a quick look at your tribalhaus generator andy, looks really good from here (didn't get much joy sound-wise from this machine, pd audio in win98 isn't all that great anyway, i'll hopefully try it on a mac at some point, should be much better)... i had been thinking about using mathematical whatsit to create wavetables that could be kind of morphed or reshaped easily, what you've done there looks quite similar to what i had in mind. i had been wondering how primitive beatboxes store their rhythms, i assumed it was all hard-wired... all the best adam </pre> ___________________________________________________________ To help you stay safe and secure online, we've developed the all new Yahoo!

oggcast~: Icecast2 returns 404
by Richard Lewis 11 Jul '06

11 Jul '06

Hi there, This may not be the right place for this problem, but: I've written a simple (my first!) pd patch which mixes several sound sources together using amplitudes set by netreceive~ and sends the result to oggcast~ In development, I tested the patch using dac~ and the result is correct. However, when I replaced dac~ with oggcast~ I got problems. Connecting to the Icecast server seems to be fine, pd says this: oggcast~: ogg/vorbis streaming client version 0.2k, written by Olaf Matthes oggcast~: set buffer to 512k bytes oggcast~: encoding 2 channels @ 44100 Hz And I've given oggcast~ the following messages: passwd ***** server 1 connect localhost soundscape0.ogg 8000 vbr 44100 2 0.6 TITLE soundscape0 But when I point my ogg client to the stream I get no sound. The Icecast logs say this: access.log: 127.0.0.1 - - [10/Jul/2006:14:39:09 +0100] "GET /soundscape0.ogg HTTP/1.1" 404 106 "-" "aRts/1.5.3" 0 error.log: [2006-07-10 14:39:09] INFO fserve/fserve_client_create checking for file /soundscape0.ogg (/usr/share/icecast2/web/soundscape0.ogg) [2006-07-10 14:39:09] WARN fserve/fserve_client_create req for file "/usr/share/icecast2/web/soundscape0.ogg" No such file or directory I've tried adding a mountpoint called "/soundscape0.ogg" to Icecast but it doesn't seem to make any difference. Does anyone know why Icecast can't find the ogg stream sent to it by pd? Setup: OS: Debian GNU/Linux "unstable" PD: 0.39-2 pd-externals: 00.20040625-4 [from Debian stable] Icecast: 2.3.1 Cheers, Richard -- -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Richard Lewis Sonic Arts Research Archive http://www.sara.uea.ac.uk/ JID: ironchicken(a)jabber.earth.li -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
