Re: living without pure-data.org

Yves, What on earth are you talking about? I am not censoring anything. I am very busy and haven't made any updates to pure-data.org in several days. I have email in my PD folder from you about an "audience~" external. Is that what you're talking about? Why don't you submit the link yourself? Your externals are great. I hope you find a way to calm down. I am certainly not out to get you.

WG: [PD] fft algorithms
by Thomas Grill 10 Apr '02

10 Apr '02

Hi all, i'd like to join in as i'm in the need of an FFT algorithm with the following properties: - in-place (or with a small workspace) - separated vectors for real and imaginary data, with stride factors - preferably also mixed-radix (for non-power-2 transforms) Alternatively, as FFTW exists (but doesn't fulfill the 2nd requirement): - is there an algorithm that transforms a vector of complex points into separated real and imaginary vectors in place? many thanks Thomas > -----Ursprüngliche Nachricht----- > Von: Orm Finnendahl [mailto:finnendahl@folkwang-hochschule.de] > Gesendet: Mittwoch, 10.

Re: [PD] (GEM) 0.87 compiled?
by ChaoShaman＠aol.com 10 Apr '02

10 Apr '02

hello pd'rs. i have no means of compiling, but have been strugling with the limits of pix_movie(and the grey/rgba error) too. so if anyones compiled .87 for windows(98), pls share a url. also, i am getting an error upon pd startup. im away from my audiopc, but its something like MMSYSTEM002 out of range... wont let me use my Awe64 Midi Input.. maybe has to do with the builtin midicrap. I'm working around through reaktor and hubi's loopback, but its really crude. any ideas. thanks joe e

[Framestein] example-masking.pd and fs.mask.pd
by Juha Vehviläinen 10 Apr '02

10 Apr '02

Hi, Here's a patch for copying with a mask.. only the pixels on areas not-black in a mask-image will be copied from source to dest. M'kay? If you have hardware acceleration, please report the frames per second you can safely use with this one.. thanks. Juha

3 questions regarding PD
by João Rui 10 Apr '02

10 Apr '02

Hello First time writing for the list. IÅ½m a complete newbie on PD but have some insights from using Max/MSP and NATO. The idea for elbows is nice, Max has it implemented and itÅ½s a little better for organising large patches. IÅ½ve been looking around for good stuff to learn on but other than the docs on the PD site I havenÅ½t found much. If there is can someone please post some links or email them to me. thanks in advance Joao > > 2) Does anyone have a link to the compiled dll for the ggee externals?

Hello, Could anyone suggest how I could make this patch of mine a bit more pretty...what sort of a GUI could I put on it if any? How can I add colours?

blocking netsend
by Joreg Diessl 09 Apr '02

09 Apr '02

halo list. i noticed that when a [netsend] tries to connect to another port the audio-output gets interrupted. in fact it's not only audio but the whole gui is blocked. especially when the destination port is not found immediately (which often is the case in my setup) that detail is very annoying. in x_net.c at line 77ff i probably found the reason for this behavior: ////////// post("connecting to port %d", portno); /* try to connect. LATER make a separate thread to do this because it might block */ if (connect(sockfd, (struct sockaddr *) &server, sizeof (server)) < 0) { sys_sockerror("connecting stream socket"); sys_closesocket(sockfd); return; } ///////// does anybody already have a nonblocking version of [netsend] he would be willing to share? or any hints on how to insert such a thread? miller? bang a lot. joreg.

Pd and Gem, some questions regarding performance
by Rory Walsh 09 Apr '02

09 Apr '02

I am currently working on a signal processing patch which just manages to make it through each test without crashing, however now I would like to use gem aswell and there is no way the two will work together in harmony! As soon as I turn on rendering or Audio the patch goes down, so I guess that I will use two computers, can anyone tell me the most effective way of doing this with 2 laptops for example, I presume that netsend and netreceive are the main objects but has anyone realised pieces using these methods and what are the main pitfalls I should try to avoid when programming a piece like this? Thanks in advance for the help!, p.s. Ricardo did'nt you just have a piece performed by the Ulster Orchestra using real-tme graphics rendered with GEM? am I right? __________________________________________________ Do You Yahoo!?
