bug: symbol atoms with dollar sign send/receive
by David NG McCallum 16 Jan '04

16 Jan '04

All, Symbol atoms with $0- or $1- send/receive don't seem to work. I'm using Pd .73.1t3 in WinXP. Even the (I think) old method of escaping the $0 with \$0 within the atom doesn't fix it. Cheers, David -- . . David McCallum . Music wants to be free . http://mentalfloss.ca/sintheta .

quattro, oss layer and 0.37-1 test3
by t.barrass＠pgrad.unimelb.edu.au 16 Jan '04

16 Jan '04

Hi, I followed the tips below and it worked, (great!) but the sound is glitchy at all -audiobuf and sample rate settings. I assume it should work smoothly- should I try a new version of alsa? I am still hanging on to 9.2 because it works with the quattro and pd 0.36-0- I don't want to lose the combination until something else works... Thanks for any hints Tim Barrass >cool, the maudio quattro is working through the oss layer again !!! >if /dev/dsp0 is your quattro, create a symlink from /dev/adsp0 to >/dev/dsp1 ... then you can start pd with -audiodev 1,2 and you'll be >able to access all 4 channels in and out ... better than frank's alsa >hack ;-) > Tim mailto:TimBlechmann@gmx.de > ICQ: 96771783

newbie, Mac OS X: problem with (certain) missing(?) GEM objects
by michael doser 16 Jan '04

16 Jan '04

Just started using GEM and PD, and while I am exploring GEM, it seems to me that certain objects for pixel manipulation that are listed as existing (pix_convolve, pix_motionblur, ...) are missing in my setup (the terminal window puts up a error message, and the object itself has no connectors), while other objects work fine (pix_kaleidoscope, pix_aging,...). I am sure that the answer is trivial, but for the while being, I'm rather stuck.. thanks - michael

pdp/X11
by plessas＠sbox.tugraz.at 16 Jan '04

16 Jan '04

Hi to all, it's very nice to start the first few weeks of 2004 with knowing that the pd-list is the first thing to read every day!! i'm currently working on this: i managed to get pdp to run, as pd is loading the lib. on apple you use X11 for an output window and you do it afaik with the object [pdp_glx]. whenever i try to send it an {create} message, pd crashes and i get on the terminal: X Error of failed request: BadMatch (invalid parameter attributes) Major opcode of failed request: 151 (GLX) Minor opcode of failed request: 5 (X_GLXMakeCurrent) Serial number of failed request: 30 Current serial number in output stream: 30 pd_gui: pd process exited I tried to supply all sorts of other messages to pdp_glx but i always get the same behavior. Can someone point me into a direction of what i'm doing wrong, or what the solution could be? thanks a lot, plus warm greetings from graz/austria, yrs Peter_P

Or at least for running cm/clm/etc. inside pd. If not, I could have used the scheme external. --

>it should work ... can you describe the errors you >get? do you get a constant distortion? >do you get this sound on all channels or only on the first 2 >channels? on all channels the sound stops completely for a second or two unpredictably about every 10-15 seconds, and there are audio pops at other times there is constant distortion on adc~ for channels 3 and 4, but generated sound is not distorted I have always had the distortion unpredictably on either pair of channels- sometimes it can be fixed by unplugging the quattro and restarting pd... Maybe I'll try updating alsa. Thanks Tim, Tim Barrass

rradical patches causing segmentation fault
by matthew shanley 16 Jan '04

16 Jan '04

i'm having problems with two of frank's rradical patches (which is dissappointing because they seem very exciting. opening analogue-0.2/example.pd crashes pd with this printed to the terminal: Segmentation fault $ pd_gui: pd process exited after that it hangs up and i have to use C-c also, opening rrad.pattseq-0.0.1/rrad.pattseq-help.pd crashes pd with similar errors returned: pool 0.2.0pre - hierarchical storage object, (C)2002-2003 Thomas Grill Segmentation fault $ pd_gui: pd process exited this happens when using alsa or jack. i'm running Pd version 0.37.1 devel, rh9, planet-ccrma, with this .pdrc: -nomidi -path /home/arkadyan/pd/rradical/memento-0.5 -path /home/arkadyan/pd/other-externals/sseq-1.0 -lib iemlib1 -lib iemlib2 -lib iem_t3_lib -lib iem_mp3 -lib zexy -lib plugin~/plugin~ -lib knob -lib OSC i'll keep checking into it since it appears to be something wrong with my system, but thought i'd post it here in case it was immediately obvious to frank or anyone else. thanks matt

PD Realtime and Jack
by J. Scott Amort 15 Jan '04

15 Jan '04

Hi, I am having a problem running pd with both the -rt and -jack flags. I am running on a slightly modified Fedora PlanetCCRMA setup (the modifications being adding xfs filesystem support to the 2.4.23.ll kernel, upgrading pd to 0.37.1 cvs and jack to 0.94.1 cvs). My audio hardware is a M-Audio Delta 66. Jack runs fine, and pd works with the simple pd -jack command, but I experience a number of DIO errors (A/D/A sync), mainly when moving/opening windows and or selecting menu items, etc. Running pd with the -rt flag seems to reduce these occurrences, but if I run pd with both -rt and -jack, it locks up when I try to produce any audio. I have used both sudo and the suid root methods to enable realtime support with pd, and both display the same behaviour. This can be reproduced every time on my system by starting pd with -rt and -jack, and then opening the test audio window, which causes a lock-up. Does anyone else experience this behaviour? Is there a way to reduce the DIO errors without the -rt flag (while still maintaining as low an audio latency as possible)? Thanks for any assistance. Regards, Scott
