complete installer for osx
by - G a r r e t t - 09 Feb '05

09 Feb '05

Hi I was at some pd training recently and there was some mention that there would be a complete pd installer with Gem, PDP etc. soon. I know of this one in development... http://at.or.at/hans/pd/installers.html But is there already one out there? Does anyone know? Any help appreciated. a+ gar +-----------------------------------------------------------+ Garrett(a)asquare.org http://www.asquare.org/ http://www.bannerart.org/ http://www.netartreview.net/ +-----------------------------------------------------------+

had to reinstall my laptop recently. unfortunately there were some issues with the pwc driver since then. i followed the instructions mentioned in pwcx-9.0/ patched the kernel (2.4.25) and made the modules. camstream ist working. but pdp pdp_v4l is complaining. (tested with 0.12.4 & 0.13.0) any ideas? (i saw that olsen had the same problem half a year ago, but his thread died..) pdp_v4l: opening /dev/video0 pdp_v4l: cap: name Philips 680 webcam type 1 channels 1 maxw 640 maxh 480 minw 128 minh 96 pdp_v4l: picture: brightness 32768 depth 24 palette 15 pdp_v4l: channel 0 name Webcam type 2 flags 0 pdp_v4l: switched to channel 0 pdp_v4l: set norm to 0 pdp_v4l: buffer size 921600, frames 2, offset 0 460800 pdp_v4l: using VIDEO_PALETTE_YUV420P pdp_v4l: frame 0 0, format 15, width 320, height 240 pdp_v4l: Opened video connection (320x240) pdp_v4l: detected pwc pdp_v4l: pwc: VIDIOCSWIN: Connection timed out pdp_v4l: VIDIOCMCAPTURE: Bad file descriptor pdp_v4l: VIDIOCMCAPTURE2: Bad file descriptor pdp_v4l: frame 1 1, format 15, width 320, height 240 pdp_v4l: VIDIOCSYNC: Bad file descriptor

Recording midi on linux
by algodon 08 Feb '05

08 Feb '05

Hello ! I've discovered puredata a few weeks ago, i mainly use midi. I run pd on Debian Sid and use jack. I've been trying to record midi with rosegarden or muse. Unfortunately, rosegarden constantly crashes after a recording. Moreover, everytime i try to use xeq or xeq_record my system freezes. So i was wondering what do people running pd on linux use to record midi events. Thanks

send~ and receive~ issues
by Piotr Majdak 08 Feb '05

08 Feb '05

Hi! I have a problem with the latency between some parts of my patches - some of them are delayed by 64 samples (=block size). I think I've created some [r~]s before other [s~]s, which would lead to this behaviour. But: I don't know which objects are affected and I've got more than 50 [s~]s and [r~]s ;-) The structure of the signal path is something like that: main patch "mypatch": [pd PLAY] [pd DAC] subpatch "PLAY": [play sig1] [play sig2] ... [play sigN] abstraction "play.pd": [readsf~] | | [s~ $1] subpatch "DAC": [dac dac1] [dac dac2] ... [dac dacN] | | | | | | [dac~ 1] [dac~ 2] [dac~ 3] abstraction "dac.pd": [r~ sigX] | | [outlet~] (playX will be set in real time to the necessary signal sigX) Then, I want to start each of the readsf~ with different delays. To achieve that I use [1( with many [delay]s, with different delay values for each [readsf~]. Even if I quantize all delay values to the block size, I've got an additional delay of the block size on some channels, which only depends on the delay values and is not a jitter on DAC buffers! Is it possible to determine the order of [s~] and [r~] having a look to the patch files? I'd like to apply the suggestion of Miller to delete and recreate all [r~]s, but what I don't know is what should I do: - recreate the single [r~] object in the abstraction "dac.pd" or - recreate all "dac.pd "abstractions in the subpatch "DAC" or - recreate the subpatch "DAC" itselft in the main patch or - something else? thanx in advance, Piotr Majdak -- Piotr Majdak Institut fÃ¼r Schallforschung Ãsterreichische Akademie der Wissenschaften Reichsratsstr. 17 A-1010 Wien Tel.: +43-1-4277-29511 Fax: +43-1-4277-9296 E-Mail: piotr(a)majdak.com WWW: http://www.kfs.oeaw.ac.at

live input processing patch
by marcus estes 08 Feb '05

08 Feb '05

I've been approached by an acoustic instrumentalist to develop a PD patch designed to process live input from a microphone. It's not my intention to wholly reconstruct the timbre of his instruments; I'm probably more interested in time-domain modulation than frequency. That said, does anyone have any broad suggestions for an interesting approach to this project? I'm not very fluent in PD's FFT capabilities, so I'm probably limited in that aspect by reusing patches from the docs. At the moment, I'm more inclined to think along the lines of a multi-lined delay system, with certain time-windows held for looping and slight modulation. I'm a big fan of the Keith Fullerton Whitman album "Playthroughs," and I understand that most of the album was produced by processing guitar sounds through Max/MSP patch. I wish that contemporary electronic musicians were more willing to publish their patches openly; I'd love to see what he used to create those sounds. I'm also a big fan of Derek Holzer's Particle Chamber patch. By increasing the sample playback length to a few seconds, the sounds retain their timbre just enough, while the jittery, polyphonic playback creates a very interesting reinterpretation of the source material. I have considered re-tooling the Particle Chamber for use with a live input, but that seems a bit tricky. Has anyone else tried such a feat? In general, I'd be interested to hear other's ideas and experiences with live input patches. If you've already done some work with this, please post your patches! I promise not to rip you off too blatantly, or if I do, proper accreditation will be given to the living-room-sized audience I have in mind for the piece. Thanks! Marcus

font problem
by Marc Lavallée 08 Feb '05

08 Feb '05

I installed puredata-0.38.0+amidi-3 from the Debian package repository (maintained by Guenter Geiger). I'm very happy because it works with jack and the ALSA MIDI sequencer. But there's a strange font problem that I never saw before; it only occurs in the menus and file dialogs, not in the patches. Please look at the included screenshot. What can I do to fix that? Thanks for your help... -- Marc

counting elapsed samples
by Ian Smith-Heisters 07 Feb '05

07 Feb '05

Hi all, I'm trying to resize an array after doing a tabwrite~ to it, like soundfiler can automatically. This seems to me to be a trivial thing to do, but I can't figure out how to get the number of elapsed samples. I considered using a [timer], but last time I used that it was extremely innaccurate, especially with high system loads. Would a combination of [realtime] and [samplerate~] be accurate? I guess I shy away from deducing the number of elapsed samples, as I'd rather get the true number somehow--but this is the only way I can figure it out so far. Any tips? Thanks much, Ian -- Ian Smith-Heisters http://www.0x09.com

grill externs lacking build files on CVS?
by Ian Smith-Heisters 07 Feb '05

07 Feb '05

I just discovered the glory that is Thomas Grill's externals, a few of which I've been looking for my entire life, and have been implementing on my own, not realizing it was already done ;). Problem is, there doesn't seem to be any build files on the CVS: http://cvs.sourceforge.net/viewcvs.py/pure-data/externals/grill/fftease/#di… All the readme.txt's say to edit config-pd-linux, but that file doesn't exist. Am I missing something? -ian smith-heisters -- Ian Smith-Heisters http://www.0x09.com

PD + GEM on usb drive
by beau25＠access4less.net 06 Feb '05

06 Feb '05

Hello, I have pd and Gem installed on a usb drive for use on anyone of a number of computers here at the lab running windows 2k. I also have some short avi video clips using mpeg4 codec. On my machine at home this worked fine, and the videos playback on the computers fine in windows media player, but when I try to load them up onto my objects I get the following message: error: GEM: pix_film: Could not find decompressor: E:/texture/cliphand.AVI Is there anyway to solve this issue? www.cypod.co.nr
