can you ask an object how many ports it has?
by John Nowak 12 Feb '05

12 Feb '05

Is there any way in Pd to find out how many inlets or outlets a named object has? This is one of my biggest annoyances in Max. I want to create a class of objects (class in the loose, non-OO sense) that all take input in the same range and can be patched together randomly to form a sort of tree of endless complexity. Doing so requires that I be able to find out how many inlets an object has, so I know how many things to script in to hook up to it. In Max, currently the only way to do it is to keep making objects and trying to hook them up, catching errors when they occur and then deleting the objects intended to be hooked up to the non-existant port: Obviously a pain, and quite slow as well, as Max doesn't perform terribly well when writing out errors to the Max window in rapid succession. - John

Fibonacci (got a strange problem in pd)
by Federico 11 Feb '05

11 Feb '05

i was writing a patch that generates the famous Fibonacci's serie (1 1 2 3 5 8 13...) and calculates sectio aurea. it seems that works ok, BUT at one point the left number stops changing. i am wondering if it is a problem of execution order... one hour ago i could say that i know enough of pd, but now i'm a bit confused. the weird thing is that if you try to restart (with the [1 2< message), it stops at different times. i overlooked at the patch, and i cannot find the problem please enlighten me (and try to ignore my bad english :)) happy coding! -- Federico

mixer

Hi! I wrote a little patch: a 4 channel stereo mixer I use to redirect one patch's audio output to another patch's audio input and/or to centralize/optimize effects usage. https://www.puredata.org/Members/dmorelli/patches/mixer.pd This is my first "all by myself" patch, so forgive my ugly coding.. davide

Re: [PD] tabread4~ vs. vd~ (was: Wave Shaping)
by Stefan Turner 11 Feb '05

11 Feb '05

>related question: which would be faster: writing an >incoming signal >to an >array in real time (tabwrite~) or using a delay line >(delwrite~) of the >same >length (ca. 4000 ms)? I would be surprised if tabwrite~ + tabread4~ and delwrite~ + vd~ don't give the same performance as they both do roughly the same thing, writing to memory and reading using the same 4-point interpolation (AFAIK). So it just depends which is more convenient, which sounds like delwrite~ + vd~ in this case. If I can make a (sort of related) suggestion: granular synths generally either use a delay line (as you mention here) or a static table (which is also cool). What I've done is make a 'grains~' patch which generates pitches, amps, pans etc. for each grain, and has several instances of $1-grain~. You can then either create 'grains~ del ...' or 'grains~ tab ...' to use lots of del-grain~s or tab-grain~s inside grains~. This handles both cases at once (and if you want can be extended further), with *-grain~ receiving the pitches etc. from grains~ and throw~ing the output back.

PD without audio
by Thomas Grill 11 Feb '05

11 Feb '05

Hi, i was trying out some message scheduling on a remote linux machine without audio support. It seems that PD has no idea of timing in case there is no audio.... i think this is really weak and there should be some kind of dummy timebase i such situations... or is there another workaround? best greetings, Thomas

Pd & a lighting console
by Alexandre Quessy 10 Feb '05

10 Feb '05

Hi list ! I am looking for a way to control 3 lights (red, green and blue) with Pd. I first thought of using variable resistances with the spots, but then I thought a digital lighting console could do the job better and easier. Did someone have a succesful experience with this ? Is it the best way to do it ? If not, what else should I use. And if so, do I need an external or an other software to control the console ? Thanks for your mutual support, Alexandre Quessy Montréal, Québec, Canada

Amsterdam pd workshop
by Marloes de Valk 10 Feb '05

10 Feb '05

_pd.workshop 23-3-2005 untill 26-3-2005 Netherlands Media Art Institute, Amsterdam in collaboration with goto10.org Guests Tom Schouten (Author of PDP, video processing within PD, Belgium) and Aymeric Mansoux (Artist, France) Fee € 150,- Admission Due to the limited capacity, applicants will be selected according to relevant professional experience and motivation. Please note all materials should be written in English. Applicants can send a mail stating name, adress, telephonenumber, and a short overview of your skills and motivation to marloes(a)montevideo.nl before March 1 Presentation March 27 from 15.00 untill 17.00 _Pure Data Pure-Data is a “real-time” graphical programming environment for audio and graphical processing. It was planned as a free, better and more stable Max/fts, which has also been developed by Miller Smith Puckette at IRCAM. It is used as a rapid prototype-software for DSP-algorithms, and also as a music instrument and universal multimedia-software. Being a mature project now, Pure-Data is getting more and more popular in the academic field for teaching and exploring computer music and new media art. It's hard to describe the possibilities of such an environment as its field of creation is almost infinite. From audio processing, to video, 2D/3D, interactivity, on-line experimentation, streaming and sensors, Pure-Data can handle all of these and provide a rock stable system which is perfect for performances and installations of any kind. _PDP PDP is a set of external objects to PD developed by Tom Schouten. They are based on the idea of processing data in packets. While it is primarily used for video, the basic structure of PDP allows any kind of data to be processed into any other kind of data. Images can be converted to textures, that can be changed into sound, re-rendered again as image, and so on. The possibilities are endless. _Presentation Sunday March 27th a presentation of the workshop will take place. This presentation will be open to an audience invited by the participants. A short overview of the workshop will be given and the participants can share the creations they have made with each other and with the audience. _Invited Guests Tom Schouten (BE) Artist and author of PDP.
