reverb_meas2.pd--this one works
by Charles Henry 26 Feb '07

26 Feb '07

Hi, list, I've made a drastic improvement over my previous room reverb patch, that is, one that works. There's still plenty of room for changing it up. The patch calculates the room reverberation and saves it on several tables on the first page, as freq. response, phase response, signal, and energy in db. The big advantage of this patch is that it improves it's measurement over time. Just set it and let it run for a while. you should be able to get very good response calculations over time. Now, the impulse could be revised into anything you want. As written, I tried to spread out my impulse by using a series of damped sines, with some sweeping motion and noise. This is the subpatch named freaky_deaky_impulses. Anyhow, it's a nice sci/fi sound effect anyhow. It will really make your room/office mates wonder what you're doing :) Now, I haven't gotten a good way to sync up the signals, but it's nearly insignificant. You can just do it by hand in the "sync_it_up" subpatch. It uses z~ from zexy and expr~ and a couple other abstractions, I'll enclose here. I hope it also works for you, let me know if you have any improvements, please! Chuck

Feature Requests for Google Summer of Code
by Georg Holzmann 26 Feb '07

26 Feb '07

Hallo! Maybe some people can give more feature requests which could be implemented within the google summer of code project. So that in the end we might have something that someone (Hans, Miller, IEM ?) can propose to google. For pd-vanilla I guess it is hard to make proposals, because (as tim said) we don't know what miller would accept - so it would be nice if miller could say something to that ! Some proposals: - GEM: make multiple windows possible (also no window) (and threaded GEM) - GEM: code optimizing (SSE2, MMX) - GEM: firewire in/output, better recording of GEM output - PDa: (Chris McCormick) porting latest Pd to PDAs (so updating Günters PDa) (patches back to Miller that make it possible to build regular Pd with no floats) - Buildsystem: rework of the pd-extended buildsystem, deb, rpm packages, integration of more externals (flext, GEM, ...), same support for all major platforms - pd-lib making a pd-core lib (see http://lists.puredata.info/pipermail/pd-dev/2006-01/005857.html) restructure all the externals in libraries and not by name (see also thread above) More ideas ?

pmpd on the Intel Macbook
by dak2＠uwm.edu 26 Feb '07

26 Feb '07

Hello I have just starting using pd on a new intel mac book. It is working great but I can't seem to get pmpd to install. It gives an error that says that it finds the file but wrong architecture. Is this a case of an intel incompatibility? Is there a UB version of PMPD that I just have not been able to locate? If anyone has got pmpd to work on this platform I would appreciate some help. Thank You Dale Kamiski dale(a)pakapaka.org

dyn~ crash
by marius schebella 25 Feb '07

25 Feb '07

Hi thomas, it is easy to build a loop which can crash dyn~, and I wonder if it would be possible to avoid a crash. I use objects, which play for a random anount of time and then they send their id when they're finished and so dyn knows that it is time to delete them. I understand wyy this is a problem, and I also found some sort of work around. but it would be easier if dyn would catch that recursion. any idea? marius. #N canvas 310 87 250 256 10; #X obj 74 116 symbol \$1; #X obj 74 66 loadbang; #X obj 74 89 delay \$2; #X obj 74 140 s killme; #X connect 0 0 3 0; #X connect 1 0 2 0; #X connect 2 0 0 0; #N canvas 639 186 681 434 10; #X obj 527 220 symbol \$1; #X obj 527 170 loadbang; #X obj 527 193 delay \$2; #X obj 527 244 s killme; #X text 416 126 that is the test abstraction; #X obj 223 194 cnv 15 100 60 empty empty empty 20 12 0 14 -258049 -66577 0; #X obj 86 271 dyn~ 0 0 0 0; #X obj 236 201 r killme; #X msg 236 230 del \$1; #X msg 86 90 newobj . a1 test1 a1 2000; #X text 55 50 CAUTION!!!

pduino set serial line device
by media.gambler 25 Feb '07

25 Feb '07

hello list! i'm trying to get my arduino board to run with pd. i work on a g4 powerbook, OS 10.4.8 with the latest installer from hans, Pd-0.39.2-extended-test7. the arduino works fine with processing, the blinking led test file works, so i upload the pd_firmware. when i open the arduino-help file everything seems to work fine, i can open a connection and get this message: [comport] opened serial line device 1 (/dev/tty.Bluetooth-PDA-Sync) - is this already wrong? is that the correct type of connection? then i set the port 13 to output and toggle the pin 13 on and off, but the led just doesn't start to blink. i'm sorry if this is a complete newbie error, but still - any recommendations? thank you in advance, emanuel

RE: [PD-dev] tcl/tk 8.5, antialising, and large fonts lead to huge cpu overhead bug?
by Ivica Ico Bukvic 25 Feb '07

25 Feb '07

You are absolutely right from a pragmatic perspective. However, having 100 refreshes top off a relatively recent CPU is quite worrisome and IMHO should not be dismissed lightly as it could manifest in other contexts as well. FWIW I did a program which had a similar feature in Qt over four years ago (with 100Hz refreshes for several concurrent timers) and its CPU usage was always less than 3% at that time. This either suggests that Tcl/Tk is a total hog or that there is a bug in a code somewhere (or both). Hence me bringing this up...

msd broken
by marius schebella 25 Feb '07

25 Feb '07

hi list, I wonder if this is an OSX problem, but my msd2D and msd3D objects are not working (see previour posts). compared to pmpd, which physical modelling object should I give the favour? (default answer: msd) are there other examples for msd? marius.

pd extended load [any] on startup
by marius schebella 25 Feb '07

25 Feb '07

hi hans, I was missing the any object in pd (osx), which is the shortversion of iem_anything. so I edited my org.puredata.pd.plist <key>loadlib33</key> <string>iem_anything</string> comments, or do you want to include that in the default plist? marius.
