Re: [PD] Polyphony and granular synthesis, etc.
by Joe White 13 Mar '11

Hi Peter, It sounds like you're missing an argument for the object. Argument 0: <integer> - Max Polyphony Argument 1: <bool> - Voice Stealing (0/1) Argument 2: <symbol> - Object name Argument 3: <symbol> - Unique ID For example: [u_makepoly 8 1 s_rhodey $0-inst] Hope that helps. P.s. We're in the process of creating some online documentation (similar to Max) for all the objects in the library. It'd be great to get some feedback once it's finished.

cannot get pix_record to work
by Matteo Sisti Sette 12 Mar '11

12 Mar '11

Hi, Time ago I succesfully used pix_record in Windows by trying different codecs until I found one that wouldn't make it crash. Now I'm trying to use it in linux and I managed to create the output file and it seems it records one black frame, but nothing more. The file seems to have the correct dimensions in pixels but it never grows to more than a few Kb. I use "codec 5" which is ffmpeg mjpeg. I have: [gemhead 99] | [t b a] | / [pix_snap 500 500] | [t b a] | / [pix_record] Well I'm simplifying it, because I have a spigot so that the situation is equivalent to the picture above only after I've sent the "record 1" message. I send to pix_record, in this order: "file output.mov" "record 1" ... now for every frame I send it a bang (and the gemlist of course) "record 0" ...now i stop banging it I've verified that pix_snap is snapping as expected (I've tried putting a pix texture after it and using the texture on a square). Any idea? It prints this message to the console when it receives the "file" message: encoding as Quicktime (QT7 compatible) but it doesn't print any message when it gets the "record 1" and "record 0" messages. thanks m.

GEM GL: invalid enumerant on Win XP
by rene beekman 12 Mar '11

12 Mar '11

The laptop of one of the students has a problem rendering in GEM. To reproduce the problem, all I have to do is to make a patch that contains nothing but one [gemwin] and one [create, 1(. Click on the message and the following error appears in the Pd window: GEM: GLEW version 1.5.1 GEM: Start rendering GL: invalid enumerant When I make a basic pix_film player patch, the same error appears and nothing is rendered in the GEM window. I've searched the archives, but did not find anything useful to help me find what causes this or how to solve this. Any suggestions how to try to solve this are more then welcome :) The machine is an HP 530, running WinXp and Pd-extended 0.42.5 Thanks Rene

> Thanks, everyone. > > So, patko, I gather poly alone should work -- I'd just multiplex > messages, so long as there are two arguments? > Yes it's possible to pass an huge number to poly object, and then polypoly, that would be the result of multiplexed values. For example if you need 7 bit words values like in MIDI standard, second value would be multiplied by 128 and then added to the first, the third by 16384 and added to the sum of the first and the second, etc ... for demultiplexing a [mod 128] would get the first value, the second with [mod 16384]-[/ 128]-[int], etc ... I have attached this example with three values. > Hans, I gather the Rj version u_makepoly is now the newest.

Quad Sound question
by J bz 12 Mar '11

12 Mar '11

Hi all, I have a 2d 'swarm' of [msd] in a GEM window. Each mass has 2 audio partials mapped to it's location, 1 on the x axis and 1 y. What's a good way of mapping the output within pd so that the visual is mirrored within a quad speaker setup. So 1 stereo pair left to right and 1 stereo pair bottom to top? I want to keep it in Pd so it's not soundcard specific. Cheers, Julian

pd_LAunch events: 1) Schedule pending wiki-fication 2)beginning of the week @UCSD
by Joe Deken 12 Mar '11

12 Mar '11

Hi Jeff, Glad to get your RSVP! 1)We are organizing many of these launch events on the fly, as responses and expressions of particular interests/focus come in. We'll soon have a wiki-version after we fill in the blanks a bit more. But meanwhile, a direct answer: 2) The time/place for the kickoff event Monday with Miller is one thing we do know: When: April 25, Monday Where: UCSD campus Calit2 (California Institute for Telecommunications and Information Technology) La Jolla CA Time: 4PM - 8PM light refreshments (no-host) NB: This event is anomalous because it is in La Jolla (north San Diego. We plan to have a couple of shuttles going from San Diego -> LA the next day (Tuesday morning), which should help. But also there is a nice train route SD-> LA along the coast, and the usual commuter air, rental-car gambits are easily managed if you prefer those.

(BTW, archiving the source in the distribution is a very, very nice feature.) Just to demonstrate my complete ignorance: It would be nice to have an external that traverses the search paths and collects all the valid class names into a list on one outlet and their corresponding paths on another. Cheers, RJK PS: Is there any nice documentation of PD internals or is it a matter of scanning the code?
