IRIX
by shreeswifty 08 Sep '02

08 Sep '02

Hello. I would hope that there is really going to be an IRIX pd still. I would like to use it on the SGI/onyx here at campus for use in virtual environments. I am focusing on the audio portion of the demonstrations & think that pd with vbap might serve wonderfully as an audio engine. cheers~ Pat Pagano, Director South East Just Intonation Society http://www.screwmusicforever.com/SHREESWIFT/ http://www.digitalworlds.ufl.edu

routing audio channels
by Paul Mathieu Brossier 08 Sep '02

08 Sep '02

Hi all. I was wondering how to mute the recorded channel on my soundcard in order to avoid loops. For example, if xmms plays an mp3, a patch like the "Test Audio and Midi" would play both original and monitored signal, which is very unlikely. Btw, on my emu10k1, alsa 0.9 rc3 will instantiate new 'pcm' and 'pcm send' mixer channels for each process running audio, but i don't see how to mute one of those without muting the main pcm. It works great when a CD is playing though. Cheers, Paul.

should be able to write list literals inside constructors, like in jMax. for example: @for {0 0} {240 320} {1 1} should call the new-function for the @for with 3 arguments that are all lists containing two integer atoms each. VSlider and HSlider should be merged together, and allow for all four directions (includes right-to-left, top-to-bottom). VDial and HDial should be merged together, and allow for all four directions. Delete key should work when editing an object/comment/etc. what about jMax's fork object ? what about jMax's "value view" (on canvas) object ? either jMax's nested patchers, or a more powerful concept: embedded abstractions (like regular abstractions but need not live in a different file) should be able to add atom types and define increfs/decrefs on them. ________________________________________________________________ Mathieu Bouchard http://artengine.ca/matju

questions

hi. here are a few questions... when will there be undo/redo functions? i can create several cords from one same outlet to one same inlet. fine. but they all look like a single cord. why? using C, how do i create a timer callback? e.g. PD would call my procedure after 50 ms. A kind of [metro] for C code. Can I change the default font from Courier Bold to Helvetica Medium ? ________________________________________________________________ Mathieu Bouchard http://artengine.ca/matju

shoutcast~ mono stream
by august 07 Sep '02

07 Sep '02

hey Olaf, list, is there any trick to get a mono stream working with the shoutcast~ external? i seem to be getting some wierd effects with all mono streams. stereo works like a charm. downsampling is also not a problem. mono, however, generates some distorted output. thanks - august.

[GEM] Gem.pd_linux: undefined symbol: openMPEG
by kurt stockman 07 Sep '02

07 Sep '02

Hello group, I got some help and we managed to compile Gem somehow...(switched to Redhat) But now on starting pd with -lib Gem there is the following error: /home/rr/gem-0.87/Gem.pd_linux: /home/rr/gem-0.87/Gem.pd_linux: undefined symbol: openMPEG Gem: can't load library Does this error mean there something wrong with some of the libraries (mesa, gltt,...) or with the compiled Gem? kurt

is it wise to to have a smaller blocksize in a subwindow?
by Andreas Sumerauer 07 Sep '02

07 Sep '02

I am playing around with IIR filters and I would like to know if it makes any sense if the blocksize in the parent window is bigger than that of the subwindow. I assume that the Blockwise calculation anyway can't be done properly because the subpatch always breaks the mold. Is there still a reason to keep the bigger blocksize? (for waveguide synthesizers, where the filter is used in a feedback path) Thanks Andreas

hi list! i got my hammerfall dsp card (pcmcia) working after a long struggle, but still i can't use it with pd. using the oss-emulation i get a lot of clicks and pops. (works fine without X11 and pd -nogui, but thats not a solution ;) using native alsa, pd refuses to start: ---------pd -verbose:------------ audio buffer set to 100 opening sound input... snd_pcm_hw_params_set_access (input): Invalid argument Sample width set to 4 bytes ALSA: set input channels to 10 ALSA lib pcm_hw.c:292:(snd_pcm_hw_hw_params) SNDRV_PCM_IOCTL_HW_PARAMS failed: Device or resource busy snd_pcm_hw_params (input): Device or resource busy pd: pcm.c:4358: snd_pcm_sw_params_current: Assertion `pcm->setup' failed. Aborted -----------end------------------- does anybody have an idea whats going wrong? if someone is willing to help me debugging i will find out the lines in s_linux.c where the errors occur. thanks regards d13b
