[hid] segmantation fault
by Jerome Tuncer 12 Oct '05

12 Oct '05

Hi list! Hi HC! I'm experiencing the segmentation faults in [hid]. I think it might be quite the same issue as: http://lists.puredata.info/pipermail/pd-list/2005-04/027405.html Has it been solved yet? Pd doesn't say much except: pd_gui: process exited Segmentation fault Pd is version 0.39-0 from Miller's site and my kernel is 2.6.13. How can everything be fresher? (-: The really strange thing is that I own two machines: one with Ubuntu, another with Debian testing. Only the one with Debian crashes Pd. Just the reverse of August's situation. He seemed to crash his ubuntu machine. At first I thought it was a kernel or gcc problem as there seems to be a few under Debian testing and gcc-4.0. Updated the whole: new kernel, freshly compiled, recompiled [hid] -> same problem. That's finally why, just like August, I'm beginning to think it's a hardware related problem... Any news on that? Thanks in advance, Jé

Hi all, I thought this article might be of some interest to people around here. http://arstechnica.com/guides/tweaks/linux-audio.ars Doesn't get into Pd or SC per se, but it is general props for FLOSS audio. -Ian P.S. Sorry for the cross-post.

Trouble with Windows and OSC
by Phillip Stearns 12 Oct '05

12 Oct '05

Hello! I'm having some serious troubles with the version of OSC 1.05 that I'm running on my Windows PC. When I send a message to the sendOSC object with more than 4 arguments, the recieving computer (using MAX) receives nothing but errors. When I send more than 6 arguments, PD crashes. Are there updates for OSC and windows machines? Will I need to compile some source code? I've never done that before so I would need some help on where to begin (getting the right compiler, files, and putting them in a place where the compiler can use them). I'm trying to avoid using MAX MSP and stick with open source software at all costs so I hope there's something out there that has addressed this problem on Windows machines. Thanks in advance!

I'm working on using autoconf. About the port, not everything is working yet, but it will. Anyway, if you need any detail about pd+ftm, i'm there! -- Pierre Duquesne

Panning with polygate~
by Juan Aboites 12 Oct '05

12 Oct '05

Hello all, This seems like a simple programming problem, but I'm finding the answer elusive: I have several signals with specific panning distributions that I want to put into the same channel on the polygate~ object (I wanted to put several signals into each polygate~ channel). The problem, though, is maintaining the original panning for each signal, since polygate~ mono-izes (to make up a word) the outputs of the pan~ object. Is this even possible? thanks, juan

I've had similar problems ever since 0.36 when trying to load paches with many scalars saved (several thousends or more). I always had the feeling of problems with graphics updates. Try saving your patch with the subwindow that contains the data closed. Even so, sometimes it takes ages to open patches with many scalars (i have experienced several minutes lag, but opened in the end). greg. >could you try pd-0.39-1test1 ?

PDContainer _ZTTSt14basic_ifstreamIcSt11char_traitsIcEE
by Gerda Strobl 11 Oct '05

Hi list, hi Georg I installed new PDContainer version from cvs--allthough I included -lib PDContainer + path into my .pdrc it does not-only when I put [PDContainer] into a patch--then I can use the objects. Also some strange message is coming on startup. tried /home/gerda/PDContainer.pd_linux and failed tried /usr/local/lib/pd/extra/PDContainer.pd_linux and failed tried /usr/local/lib/pd/externs/PDContainer.pd_linux and failed tried /usr/local/lib/pd/iemabs/PDContainer.pd_linux and failed tried /usr/lib/pd/extra/PDContainer.pd_linux and failed tried /usr/lib/pd/externs/PDContainer.pd_linux and succeeded /usr/lib/pd/externs/PDContainer.pd_linux: /usr/lib/pd/externs/PDContainer.pd_linux: undefined symbol: _ZTTSt14basic_ifstreamIcSt11char_traitsIcEE PDContainer: can't load library thx Gerda

shelf filter
by derek holzer 11 Oct '05

11 Oct '05

Dear list, I've been trying to make a classic 3 band "DJ EQ" with a slope steep and attentuation sufficint enough to kill all frequencies in the selected bandwidth range if needed (a "kill switch"). The filter should also have as little possible resonance at the crossover frequencies to avoid coloring the sound that goes through it. I simply lack the math knowledge to program [biquad~] by myself, so I'm playing around with the filter helpers from the GGEE library. The [lowpass], [bandpass] and [highpass] objects seem simple enough, and I've gotten pretty close to what I need from there. But there's still the issue of the crossover frequencies. The slope isn't steep enough. So I checked out [highshelf], [lowshelf] and [hlshelf], but these are very confusing, espc the "gain" parameter. It seems I have to scale the output gain by the same ratio as the biquad frequency gain to maintain the original sound going through? This works at high frequencies, but not at low ones. So what would be the proper ratio to scale the output of the filter by in this case? The [hml_shelf~] abstraction from IEMlib is similarly not too helpful, as the output also needs scaling (by an unknown ratio) to get the desired frequency range back up to normal levels. I also checked out the LADSPA "DJ_EQ" plugin, but either the attentuation isn't sufficient or the cutoff not steep enough because I still get a lot of unwanted sound from the other bands. The JackEQ JACK client doesn't work properly on my machine [Gentoo PPC], so I can't tell if that would work better or not. So besides going back to my flunked algebra and trigonometry classes to cook up a proper biquad, can anyone give me some clues on how to realize this seemingly simple filter properly? thx, d. -- derek holzer ::: http://www.umatic.nl ---Oblique Strategy # 108: "Look closely at the most embarrassing details and amplify them"
