It would be so nice to have an exegesis of each number and object in the patch. As you say in your book, digital filter design is a huge subject. I'd love to be able to honestly say that I would like to devote myself to learning it, but truthfully I just want a cookbook for creating a low pass filter to do the application of oversampling. > > To change the value of 7500 or 16, adjust beta accordingly and repeat. > > cheers > Miller _____________ David F.

TKWidget Text and the Append message
by Mike McGonagle 11 Nov '08

11 Nov '08

Hans, I finally got around to putting this in place, and I found that the append message doesn't seem to work. It does appear to be there, as it prints out 'textwidget_append' to the console, but nothing appears to get appended to the text... Attached is a basic example. Mike -- Peace may sound simple—one beautiful word— but it requires everything we have, every quality, every strength, every dream, every high ideal. —Yehudi Menuhin (1916–1999), musician

Understanding Oversampling
by David F. Place 11 Nov '08

11 Nov '08

Hello: I'm trying to understand J07.oversampling.pd. Is the structure of the 3-pole, 3-zero Butterworth low-pass filter specific to the 16x upsampling? Should it be different for 32x upsampling? Cheers, David

compiling pd vanilla on os x: ld problems
by Rich E 11 Nov '08

11 Nov '08

Hi all, I'm trying to build the latest pd-vanilla (0.41-4) on a Mac PowerPC G4 running os x, but seeing strange linking errors. The computer is a hand-me-down from another programmer, not the freshest install to say the least. Configure works fine, but when I make I get a warning that "-arch i386" was specified to ld, and then errors about undefined symbols. I realize this is something wrong with my build tools, but don't see where to find the solution. I tried re-installing xcode 2.4, didn't help. Also, I compiled a non-pd related c library just fine.. Any suggestions? regards, Rich

Detroit-area Patching Circle?
by Darren Landrum 11 Nov '08

11 Nov '08

I suppose it's too much to ask, but I see all this talk about patching circles and people getting together, and it's all so far from me. So, I'll hold out just a little hope that there are a few folks in the Detroit area (I'm in Port Huron, about an hour away from downtown Detroit) who might be interested in regular meetings. Thank you for letting me use up some of your bandwidth. Regards, Darren Landrum

Hey, I cc'ed the list since I think many people can contribute to this topic. That's great! Personally, I haven't really used the wiki page to organize a meeting, but some have. I basically talk to lots of people in person, and email them. I get a group of people to commit to a date and time first, like maybe 5 people. Then announce it, sometimes advertising using their names. I was running regular Arduino Hacklabs, and made a page for that if you are interested: http://www.arduino.cc/playground/Main/NYCHacklab I have heard there are some Pders at Art Institute, I don't know if you have any connection to them. .hc On Nov 9, 2008, at 10:59 AM, Anthony Curry wrote: > Hello All, > > I'm interested in meeting with other Pd'ers in the Chicago area. > How can I / we use the community page to establish a cirle in > Chicago, USA as has been done in Copenhagen and Graz? > > Happy Pd-ing. > > Anthony C > Chicago, IL > > > ------------------------------------------------------------------------ ---- 'You people have such restrictive dress for women,’ she said, hobbling away in three inch heels and panty hose to finish out another pink-collar temp pool day. - “Hijab Scene #2", by Mohja Kahf

hi Rob. no that wasn't meant to be off-list, however it might have acidentialy got off-list ;( sorry for confusing, i meant 'my squat' .. i think i was ansvering 10 emails in a row at that point and hadn't paid enough attention to what i actually wrote ;..( i think we actually should shift this discussion to pd-list or everyone is on openlab-list anyway?

dubstep bass/other patches?
by Damian Stewart 10 Nov '08

10 Nov '08

hey listers, just wondering if anyone has any nice patches for making dubstep noises, or tips for doing dubstep style production in Pd. in particular i'm interested in making the huge stupid bass wubwubwubwubwubwub noise - i figure it's a square wave passed through a highly resonant lowpass filter, with the wubwub coming from modulating the filter cutoff frequency, but i don't have access to club-style subwoofers so it'd be nice to know some tricks to make it sound genuine. for example, do you put another layer of pure sine under there to flesh it out a bit, or use pairs of square oscillators in detuned octaves, or whatever.. any thoughts appreciated. chur d -- damian stewart | skype: damiansnz | damian(a)frey.co.nz frey | live art with machines | http://www.frey.co.nz

Hey guys, Glad the tutorial was useful. The creaky door and thunder patch with Alberto's 'Outer Space' patch sound perfect.
