Pd 0.46-6 for Debian distro
by Joel Corelitz 19 May '15

19 May '15

Is there a way to load the most recent version of Pd (from Miller Puckette’s site) using "get apt install”? I’ve successfully loaded it onto my Pi using file transfer and I can get it to open, but the one that’s part of the Debian distro responds to terminal commands, etc… (At least that’s the impression I had regarding both installation methods.) But doesn’t have native OSC support, which I need. --Joel Corelitz / waveplant http://www.waveplantstudios.com (http://www.waveplantstudios.com/) joel(a)waveplantstudios.com (mailto:joel@waveplantstudios.com) 312-348-5798 (tel:312-348-5798) (voice & fax)

Error attempting to uploading a file in puredata.info/author
by oscar pablo di liscia 18 May '15

18 May '15

Hi, I have my personal page at: https://puredata.info/author/pdiliscia For several years I uploaded there part of my work related to PD. (Patches, Externals, Documentation, etc.) However, since two days ago, I could not add anything more to the site, only to update the files that already are. When attempting to create a new file or folder I get an error saying: "either the object does not support this operation or you don't have permission for this operation" I got no answer from pdmeister(a)iem.at I don't see in the site any documentation that may help in the issue. Any help will be appreciated. Oscar Pablo Di Liscia

peaking filter
by Jeppi Jeppi 18 May '15

18 May '15

Hi all,what object would you recommend for a (constant gain) peaking filter? something like the parametric Eq described in http://www.musicdsp.org/files/Audio-EQ-Cookbook.txt or the one described in https://ccrma.stanford.edu/~jos/fp/Generating_Pure_Data_PD.html?Anything like that already available as an external? Thanks in advance,josep m

I think i am going to try to create a nice VCF~ similar to the Curtis filter that DSM is selling for 180$ that is what i wanted to buy recently anywya so i am going to give it a shot does anyone have a NICE Vanilla VCF i can try that does not require any external installation?

Try disis_munger~ which is a flext external that also runs on RPi and is included with the pd-l2ork builds. The help file provides live input example. NB: RPi's CPU is fairly limited in terms of computational power, so it is rather easy to choke it when increasing a number of concurrent voices.

pd in a eurorack modular system
by Pagano, Patrick 17 May '15

17 May '15

Hi I am building my first modualr system with a little grant money i got for research. For the first 1000$ i got a beginner Pittsburgh Modular system and one envelope module. FOr the second 1000$ to complete the grant i am considering http://www.qubitelectronix.com/#!nebulae/c23nm The nebulae says it will run custom Csound and pd code which i find very intriguing. i would LOVE to buid a patch with about 3 simple effects that are not in the traditional analog modular world a sample and hold and a simple RM Granulation PV FFT S&H Ring Mod and be able to toggle through the effects. It says it runs pd-vanilla Has anyone on the list seen/used or can confrim that the code actually runs properly I have been searching through the web and Muffwiggler and i have not seen any proof of it running so i am skeptical but still curious before i lunk down 400+4 i want it to run my patches or at least a detailed how to please let me know if you have any experience with it.

Looking for solutions to the "indexing into large arrays" problem

I'm finally getting around to trying to modify my looper patch to be able to index into long arrays, using the solution suggested. I am sorry to say the "onset" for [tabread4~] does not seem sufficient IMO (if my understanding is correct). The single precision index provided by the left inlet of [tabread4~], which seems safe in the range (0..150,000), which is typically driven by a phasor~, is *added* to the right inlet. So instead of first hearing distortion at 150,000 samples --- 3.4 seconds at 44.1Khz) -- this is the example in B15 "Using Onsets into Tabread4~ to provide accuracy"-- Now, we have deferred the problem to 300,000 samples, *6.8 seconds!* Do I have this right?

downsampling with [block~] causing artifacts
by Alexandre Torres Porres 16 May '15

16 May '15

Howdy, I have a patch attached to show how downsampling produces artifacts/distortion for a 440 sine wave. I don't hear "aliasing" and I think it couldn't be foldover at all because 440 is below the nyquist. Moreover, I hear harmonic higher pitches - so it seems like a harmonic distortion from the original sine wave that I can also still perceive. This kind of distortion happens when you have a reduced dynamic range. Another things is that I heard someone saying how increasing sample rate improves dynamic range, but I can't find this information around. Not sure it it's really true, if someone says it is so, please send me a source, ok? But the thing is that the artifacts from this patch could be the result of a smaller SNR. Hope you can help me sort this out. thanks

16 May '15

Attemping to create a folder in my page at puredata.info I received the following error message. What I am doing wrong? I`ve got no answer from pdmeister so far. Mensaje de Error *!* The action against the *folder.2015-05-13.9108981052* object could not be carried out. One of the following constraints caused the problem: The object does not support this operation. -- OR -- The currently logged-in user does not have the *Copy or Move* permission respective to the object.
