pd&debian&lowlatency&alsa&hdsp
by plessas＠sbox.tugraz.at 11 Dec '03

11 Dec '03

Dear List! trying to build a low-latency kernel on debian for use with pd 0.37 and alsa and an Rme HDSP card. I read a lot about different patches one can apply, but most information about those is from 2000/01 when 2.2 and 2.4 kernels were new and shiny. Has anyone had success doing this so far, and with wich patches on wich kernels, and how low is the resulting latency you get? Any advice is greatly appreciated! Peter P.

PDer's in sweden
by tdunstan＠ihug.com.au 11 Dec '03

Hi crew Just a quick question. I'm wondering if there are any PDer's in Swedish universities. I'm planning an exchange to Sweden and I was wondering if there are any like minded folk out there. I'm looking at perhaps Lukea uni in Pitea. Can anyone recommend somewhere, I've got to get out of my shelter in Melbourne, Australia and find something new. Thanks Tom

Dear Frank & List, thanks, that really sounds easy, so i'll give it a try! In addition to these patches i heard of a "100Hz patch". Has anybody got some experience with this? Thanks! Peter P.

RE: [PD] First time PD Linux user: what Linux to get?

I did as Derek Mentioned and started off with RH9 and planet CCRMA. However until a few days ago they were still on version .36. Verion .37 is loosely supported with the Fedora stuff on planet, but this was after I made my switch to Debian. That being said, the install was smoother than butter, everything went perfect. I can't give the ccrma guys enough props. The install was pretty painless using woody 3.0r1. However on Monday a version of Sarge was released with the new installer, this may or may not be easier to use. Woody installed painlessly (ok not so painless, it was completely clueless about my now ancient apple monitor, but that only took some mild googling to find the manuals and the Vsync and Hsync stuff) with 2.2 kernel (not real time of course). I then used the Agnula packages (www.agnula.org) to upgrade my kernel and add alsa support for my midiman 4/10. This also went well. What has been slightly more painful has been getting the most recent packages onto CD (this machine has no net access). I have spent the last 2 days downloading all 24 testing/unstable disks (16 gigs!!!! Gotta love jigdo and a 100mbs pipe), so I can do a nice app upgrade this weekend. m.

PDffmpeg stream counter-WSIS @ geneve
by rama 11 Dec '03

hi, as u might know, the World Summit on the Information Society is being held at Geneve during these days. many groups and individuals from a lot of countries are met together at a parallel event called "WSIS? We Seize!" which is part of the geneva03 project as an action of protest. "3 WHAT'S HAPPENING? There are three projects within WE SEIZE: PolyMediaLab, HighNoon and the StrategicConference (S-CONF)." taken from http://geneva03.net we are running an ffmpeg stream from pd having several video sources (a loop is playing now until activities begin before Thursday 11 midday) you can check http://ayp.unia.es:8090/test1.mpg it seems quite stable for long hours, no audio for the moment though. all pd'ers willing to joing the action/event are welcome to send streams and also pick. i have some working (buggy) patches for doing mp3 streams from the mixing of several audio sources (2 hdd ogg, 2 incoming mp3 streams, 2 soundcard inputs, and 2 p2p pd audio inputs) and also one for mixing video and stream out to ffmpeg or p2p to another host running same patch. that is published (but not announced yet) at http://rama.xicnet.com. feel free to download, modify, redistribute, destroy, recreate, whatever. stream u soon! cheers,r -- rama <medialist(a)xicnet.com>

portmidi assertion fails
by Johannes Taelman 11 Dec '03

11 Dec '03

Hi I'm currently getting assertion faillures in PD (on winxp, with a hyperthreading P4 CPU) Program: pd.exe File: ..\portmidi\pm_win\pmwinmm.c Line: 441 Expression: FALSE It happens once in a while. I'm actually sending a lot of midi data into pd (from a Novation Remote25 usb-midi keyboard, and a Roland Handsonic hand percussion controller through my HDSP soundcard). I can click on ignore (multiple times, the assertion fault appears in dozens) and go on with pd, but as long as the dialog is there, no midi is getting through... Has anyone seen this, or knows a solution? Is it a midi parse error? Could I just remove this assertion in the code and recompile? thanks, j#|@

Hello! I would include the email to which this pertains, but I have accidently deleted it... Anyway, to the person that asked the question about: bad screen distance "pdtk_pd_dio" This answer helped me, except that now I dont have jack drivers even though I have the CVS from sourceforge, and I have compiled ./configure --enable-jack Apparently tabwrite and jack fight unless you have the cvs of pd...

by Jerome Etienne 10 Dec '03

10 Dec '03

hi, im looking for a way to compute a arccos in pd ? i fail to find an object directly computing it, did i miss it ? is there a way to compute it in a more indirect way (e.g. with a "limited developpment" really free translation of the french "developpement limite") ?

newbie question fiddle~ bonk~
by MilesOkazaki＠aol.com 10 Dec '03

10 Dec '03

pd list, I have PD running on Windows XP and Max OSX. In both cases, help-bonk~.pd responds to an audio signal running through the soundcard but help-fiddle~.pd doesn't. Is there some difference between these two in terms of how they receive the audio signal? thanks, -M.Okazaki
