RE: [PD] PDP and quicktime pdp_qt
by Patrick Pagano 19 Apr '06

Jamie is right Do NOT USE the libquicktime from fink. There is a version included with pidip source libquicktime.so.0 or .2 that should be used. I had this same problem with the fink version.

reading and handling of multichannel data request
by Florian Grond 18 Apr '06

18 Apr '06

Dear List, Is there for PD on Windows any possibility to have an oscillator bank with say 50 to 100 oscillators, that accepts a list of 50 to100 components to set/change the frequencies of this oscillators dynamically, possibly smooth with a line~ object? How can I best read in large amount of multichannel data, to conveniently control such an oscillator bank? msgfile from zexy cannot read the following file on my PC: 1,2,3,4 7,6,5,4 3,4,5,6 9,8,7,6 7,6,5,4 2,3,4,5 I get the following error: tried C:\\Programme\\pd\\doc\\5.reference\\help-zexy\\test.txt and succeeded error: msgfile_read: unable to open test.txt. Any help very much appreciated, Thanks Florian Grond -- /////// / |< ||| | ZKM | Zentrum fuer Kunst und Medientechnologie /////// / |< ||| | ZKM | Centre d'Art et Media /////// / |< ||| | ZKM | Center for Art and Media LorenzstraÃe 19 D- 76135 Karlsruhe Tel: +49. 721. 8100-1002 Mob: +49. 177. 3099094 Fax: +49. 721. 8100-1709 www.grond.at

Re: [PD] flib for Irix/SGI

If this is something you need, let me know, and I will add Irix support to the makefile. I will need your help testing it though, as I don't have access to an Irix box. Jamie Arie van Schutterhoef: I was wondering whether there are people using Jamie Bullock's under Irix/SGI?

eq viz?
by james tittle 18 Apr '06

18 Apr '06

hey, ...I'm a bit stuck on this, so I thought a few extra eyeballs could help out :-) Beware! I may have coded alot with pd and gem, but am basically a newbie to using the audio side! Anyway, i'd like to create a series of simple abstractions that provide visual meter-ing of input sound in GEM, like an EQ histogram, fft spectrum, and other things... ...in this patch, I ripped a bunch of stuff from PureMeasurement (specificly from the pm_decayrecorder.pd patch) and am trying to get the output into a bunch of gem bars...if you run the patch, you can see the meters on the canvas bumping up and down individually, but the gem version (which is run thru a [multiplex] with the intention of grabbing one band per "gemhead repeat") seems to be registering the value across all bars...anything obviously wrong? Or does anyone have something similar? thanx, jamie

Gem window res problems
by Jonathan Goodwin 18 Apr '06

18 Apr '06

Following on from my question earlier, I figured I would annotate my patch and attach it so people can understand it a bit better: Basically, when this patch is finished I will be outputting it via a digital projector, so it will need to be at least 720x576 pixels res (PAL tv res). Patch Key: Yellow area: Live feed from webcam Red area: 500ms Snapshots from webcam feed Green are: this is where the background movie will go that the live feed will be keyed over. I know that everything here is not refined yet, and that the chroma-key is not set up yet, but this is basically how my patch will probably be set up. I will be overlaying a derivative of the red area feed over the green area feed. But for some reason, I cannot get the pix_snap2tex feed to match the res/proportions of the live webcam feed. The snapshots tend to appear a lot smaller, with kind of garbled screenshot data/noise around the edges. If anyone could tell me what I'm doing wrong, you'd relieve me of much frustration! Jonathan
