Gem- Text2d - Trouble
by matohawk 12 Nov '09

12 Nov '09

Hello, I made a test with Pd version 0.42-5 and GEM: ver: 0.92.1 GEM: compiled: Sep 22 2009 And the text2d object with antialias, I view a crasy performance difference between windows and Mac. Same patch - same Pure Data - Same Gem Patch : http://www.th-th.fr/DOCS/Test-Gem/main-test.pd MAC OS X - 10.5.6 2.8 GHz Quad Core Intel Xeon => CPU load in percent 25% http://www.th-th.fr/DOCS/Test-Gem/MAC-Test-Texte-2d-antialias.png Windows XP - Service pack 3 2 GHz Intel Pentium M => CPU load 4.6% http://www.th-th.fr/DOCS/Test-Gem/PC-Test-texte-2d-antialias.png Is that normal? Cheers Thomas Thiery

Research delay
by Gintaras Lau. 12 Nov '09

12 Nov '09

Hello, I'm making a diploma work and need help from community like this to assure that my work is related to science or is a part of it, even if it (what I did) just a small improvement on the other hand. There is no information about it in my native language, so sometimes I get confused about what I'm looking for, because many things are interesting to me and the field is getting wider and more confusing. I have tried many delay effect patches and found one made by Maelstorm on pd-forum. I upgraded it to stereo, mounted into structure I needed and something I call an improvement. This delay processor does something what I think might be considered as humanized behavior. It takes audio of the musician (Saxophone) and creates an echo effect (tap function included), but output of the echo signal is controlled by the previous amount of volume (vu) of the input. You can set a feedback at the maximum amount, but if there is no input signal at that time from the instrument, than echo goes down (gradually or fast) as well. It sounds pleasant because there is another parameter that appeared during the construction process, an interpolation time or sensitivity how fast it follow the input ([line]) . So the amount of echo volume can't exceed the the amount of dry signal, what I take as an aesthetic value in a live performance (tested). Any pd user know how simple it is to make it using this software, but I couldn't find anybody did or mentioned about delay controlled by the signal witch has a human or instrument property (amplitude applied as control). I work with DAW's like Cubase and know that there is no delay like that. I want to ask if the community has an opinion about my idea, taking all possible aspects that comes to his mind. I think there is no better place as this to give such questions and use it's answers as vector to continue research. In the community I am now there are no students or lecturers that use pd and any other interesting things that it offer. So at least truth has to come out of my research. Thank you.

Filling an audio array. Question..
by Rory Walsh 12 Nov '09

12 Nov '09

I want to fill an audio array of 1024 samples with two exponential curves, a simple attack and decay envelope. While I can easily create the curves I want I'm have a hard time putting them into an array. What is teh best practice for loading different curves into an audio array using tilde objects? I've attached a patch that creates the two curves, if anyone can show me how to get them into the array one after another I'd be most appreciative. I've tried to use a delay object with a 4 millsecond delay but that was no good for me. Again, any suggestions of ideas are most welcome. Rory. p.s. as a Csound user I've got really used to using GEN routines. I'm happy not to have them in Pd as it forces me tothink about how the routines work, if I could only figure out how to get them into a table I'd be happy!

PD/GEM examples
by Joseph Gray 12 Nov '09

12 Nov '09

Hello, Cornish College of the Arts has invited me to teach a brief and very introductory workshop in Pure Data in their art department on Monday. Wondering if anyone on this list would have any suggestions of works to present to give the students an idea of what the software is capable of and how it can be applied, particularly from a sculptural/ installation/video art perspective. Any or all suggestions are welcome. Best, Joseph Gray http://grauwald.com

Spanish manual
by Jeffrey Concepcion 11 Nov '09

11 Nov '09

I see the link for the spanish version of the manual isn't working. Does anyone know if it's active anywhere? i could do a translation but i don't know how to create websites, nor how to make pdf files actually. http://puredata.info/docs/manuals. Puedo ver que la pagina de la traduccion al español del manual no funciona. alguien sabe si esta activa en alguna parte? yo podria hacer una traduccion pero no se hacer paginas web, ni documentos en pdf.

[PD-announce] nusmuk audio
by cyrille henry 11 Nov '09

11 Nov '09

hello, i packed few bit of code into a lib aimed to improve audio synthesis quality within Pure Data. This collection incorporates the best band limited oscillator i saw in pd, objects that read table in a more flexible way than the Pure Data native one. Some filters and various objects are also available. http://www.chnry.net/ch/?Nusmuk-audio&lang=en well, nothing mandatory, but can improve sound sometimes...
