The configuration is usually done in the GUI. In Pd the GUI is implemented in tcl/tk. Reading and writing the configuration is done by c code that's platform-specific. I think it makes more sense if that code works with human-readable text files ('simple' xml is human-readable). Maybe the path to the config file would be different according to platform but the file format doesn't need to be different. Isn't OSX already using xml for its own config files? Martin

It's just an ASCII text file with easy-to-understand tags. It could even include a full set of usage instructions as comments. To me the command line is arcane and the registry even more so. Martin

Re: [PD] buffer overflow with pix_image
by user ＠ earweego 14 Sep '06

14 Sep '06

thanks, folks! so you say that pix_film is a pretty substitute for pix_image. I dont feel like trying and put all 500 images into a .mov, as they're all different dimensions and I guess that would not end up nicely. I'll try the pix_film thing! about the crash report: the _weird_ thing is that there is none! Pd and pd just vanish so discretely during the nightly tests that I get back in the morning and there is not the slightest trace left that they were ever on... no MAC notification, no crash log,... hmmm. im now tryin to send some OSC messages to SC where I can log them and at least get an idea about how long it run before crashing. curoius about this night;) bests, .hh. >chris wrote You can use pix_film to load images on the Mac. That has proven stable for months on end of loading movies and should be similar for still images. You could also put the stills into a single movie file using Quicktime Pro or an Applescript. On 9/13/06, user @ earweego <pd(a)earweego.net> wrote: for an installation in ZKM, we are using a GEM-based patch where a dozen of cubes are textured via [pix_image] with jpg-images of 35kB on avg. each cube changes its image about once per second, and we are getting heavy crashes after less than an hour. using a MAC Dual G5 with OS X 10.4.4, 1.25GB RAM and PD version pd++_0_39_1 by James Tittle which is amazing for the rest - even fixed the tedious titlebar issue :) apparently, the image buffer is not cleared after the new image was loaded, and thus the RAM is overflowing. We could work around this problem by changing the images less often, but it feels dirty as it would just _delay_ the crash to a time beyond exhibition duration. Would it help if the images had smaller pixel sizes and thus take less memory? I guess the bug is known, but is anybody able to fix it before the opening in one week ? any hint would be greatly appreciated, bests, .hh. _______________________________________________ PD-list(a)iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list _______________________________________________ PD-list(a)iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list

> > Then we would have to think about the underlying storage format. > > i agree. i'm sick of library-specific hacks on cramming what they need to store in the .pd format. or user-level hacks using symbol manipulation objects. it's time for a format that can be at least say, 80% useful and flexible and diffable moving forward. RDF anyone? RDF seems like overkill here. Simple xml with a start tag and end tag for each item, one item per line, should work fine everywhere. As an example in my registry I have under My Computer->HKEY_LOCAL_MACHINE->SOFTWARE->Pd: audioapi 3 audiobuf 70 audioindev1 0 2 audiooutdev1 0 2 defeatrt 0 flags loadlib1 Gem nloadlib 1 noaudioon False noaoudioout False nomidiin True nomidiout True npath 0 rate 44100 standardpath 1 verbose 0 ...which could be xmled as: <?xml version="1.0" standalone='yes'?>  <audioapi> 3 </audioapi> <audiobuf> 70 </audiobuf> <audioindev1> 0 2 </audioindev1> <audiooutdev1> 0 2 </audiooutdev1> <defeatrt> 0 </defeatrt> <flags></flags> <loadlib1> Gem </loadlib1> <nloadlib> 1 </nloadlib> <noaudioon> False </noaudioon> <noaoudioout> False </noaoudioout> <nomidiin> True </nomidiin> <nomidiout> True </nomidiout> <npath> 0 </npath> <rate> 44100 </rate> <standardpath> 1 </standardpath> <verbose> 0 </verbose> ...although I would change <loadlib1> to just <loadlib> and allow as many of them as you like instead of ten.

urgent: carillon by text message
by Max Neupert 14 Sep '06

14 Sep '06

hi list, there is the following opportunity: for a festival radiorevolten in halle/saale an artist was supposed to programme an interactive work with the cities carillon (glockenspiel) this artist gave up on it last minute. so there is an urgent need for someone stepping in this place. the idea is that anyone can send sms text messages to the carillon during the festival and it will play an signature tune of an radio station. so if the text message contains "RADIO VATICAN" its signature tune will be played by the bells. is has to be woking by next friday! if nobody is up for it the project will be dropped. there is a budget of 750 Euro. the carillon is the worlds second largest and is MIDI controllable. it could possibly be the first one controlled by pd... please contact instantly also: if anyone has connected a phone to read short messages in pd, please step up- http://de.wikipedia.org/wiki/Roter_Turm_(Halle) http://radiorevolten.net/

Hey Pders, <http://www.infolaunch.com/~daveb/> is a groovy little function grapher I just found out about, which is really useful for designing procedural elements like envelopes in your compositions. apt-get install geg. Best, Chris. ------------------- chris(a)mccormick.cx http://mccormick.cx

Pd to CV for a Moog (OT)
by Chuckk Hubbard 14 Sep '06

14 Sep '06

I'm writing a proposal for independent study at my school, and my goal is to take a few lessons in tuning from this microtonal composer, compose a piece using my Pd sequencer, and somehow use the output to drive the newly refurbished Moog at my school (supposedly one of the first 5 Moogs ever made) to create a finished track. MIDI-to-CV converters are expensive, and of course MIDI is already inadequate. So I'm thinking of circuits I've looked at before and wondering if plain old audio from [sig~] objects could be made to represent voltage, from -1 to 1, or 0 to 1 with -1 being off, and externally converted to the proper scale for CV input to the Moog. The music tech supervisor has added a module that makes the thing polyphonic, which I suppose I'll have to understand to do it. I guess my other option is to just use audio output, and process it through the Moog's modules. Can anyone make any suggestions? How can one interface between Pd and control voltage? Could I jury-rig regular audio output to do it? Thanks. -Chuckk -- "Far and away the best prize that life has to offer is the chance to work hard at work worth doing." -Theodore Roosevelt
