Hi ! I'm working on the modelisation of the basilar membrane. Does an implementation of the GammaTone filter exist in PureData ? (The model is from Patterson) Thanks ! Thomas

gem 0.90 - invisible output - problems with direct rendering on nvidia?
by Christian Klotz 09 Nov '04

09 Nov '04

Hi all, after replacing my fedora with debian again :) I compiled gem 0.90 from cvs and everything went fine. But there is one really strange behaviour. Once I open a pd/gem path it doesnt show anything. Sometimes the blue square help patch works but usually there is nothing to see - and there are no error messages. It seems to be something linked to Direct Rendering - if the console gives a "Direct Rendering enabled!" there wont be anything shown, if it doesnt, everything works fine. But is there a way to control the Direct Rendering? glxinfo says that my geforce 5700 can handle direct rendering. I compiled gem using the nvidia glx 1.0.6111.1 driver for my geforce 5700 card. Does anybody know something about this? thanks in advance, cheers. christian --- Christian Klotz Kunsthochschule Kassel / School of Arts Kassel ::digitalpool

GEM - problems with pix_video
by Thoralf Schulze 09 Nov '04

09 Nov '04

Hi list, my gem (0.90 running on win 2k, pd version is 0.37.4) heavily dislikes my usb camera ... I intend to use the latter as a video source. Loading any of the patches in the 04.video dir causes pd to crash, the same happens if i place a pix_video object on the canvas. I can happily capture frames with virtualdub, however - so i assume this is not a driver issue ... thank you for your answers, Thoralf. ___________________________________________________________ Gesendet von Yahoo!

0.38, osx, jack, osc, gem...
by adam overton 09 Nov '04

09 Nov '04

hey there i'm sorry if this has all been covered in past posts, but i searched the archives and couldn't find what i need... currently i'm running 0.37-2 on OSX. i just downloaded the 0.38v7 binary and am having the following troubles: -i can't load the OSC and Gem libraries. i've tried two methods: going to the 'Startup' pane, writing 'Gem' in one slot, 'OSC' in another, clicking 'Apply' and 'Save All Settings', quitting, then restarting; i've also tried doing it as a flags at the bottom: -lib OSC -lib Gem. both methods get me 'can't load library'. am i doing something wrong? -i can't get this version pd to connect to jack osx. i couldn't get this to work with my earlier version of pd (0.37-2) either and was hopeful that maybe this would now be possible in this release. do i maybe need to load a library for this as well, or is this something that will be added at some point? as for my current work with 0.37-2, are there any solutions yet for hooking up with jack-osx? i saw that someone released a version of pd 0.37-0 that is supposed to work with jack (http://www.meskalina.it/qwikiwiki/index.php?page=JackOSX), but i'm somewhat reluctant to download and install a slightly earlier version of pd. maybe someone can allay my fears... thanks so much for the help!!! adam aoverton(a)calarts.edu 661.373.8679 cell ... 661.294.1885 hm http://www.calarts.edu/~aoverton

MIDI to CV-GATE patch [free smooth.pd included!]
by Federico 08 Nov '04

08 Nov '04

hi, is there an already done MIDI-to-CVGATE patch for pd? i was building one yesterday. i started with basic functionality, then i wanted to add portamento, and things became more comples (there is the need to implement a stack of voices, but i still haven't the knowledge to do it) ... so before to start the dirty job i was wondering if there are any components that semplify this task. : - ? until now i wrote an "exponential data-smoother", wich i attach as a welcome (because it is my first post, even if been lurking for a long while).. hope you like it :)

(correct me if i'm wrong). my problem originated from the pd 0-37(devel) packaged with demudi as well. i'm am in the process of trying to nut it out by comparing this with 38-test 7 and 37 (non-devel). but as yet have not found an answer. as far as i can see, my problem is caused when i used lots of sampling and tabreads~ + delreads~. i'm kinda confused because i used to use fedora core 1 with pd-37 and i remember using a patch with 200mb of sampled material without too much problem. this is why i think it is a demudi thing...but then again i'm no linux guru...yet ;) i hope ths helps.... and eventially helps me. tom

Re: [PD] flext problem???

Then it's a but in the A/Demudi packages. Vasp is build with flext-shared, but either flext shared is not installed, or it's installed somewhere not in the library path. I think, Guenther is planning to move libflext to /usr/lib or /usr/lib/flext anyway (?) so this will not happen in future packages (or maybe not even in the current experimental packages). The syncgrain~ problem either is, because sndobj is not installed, or maybe, because (lib)flext was built withouth sndobj support. In either case, this also likely is a bug in the A/Demudi package.

makefilename containing spaces
by Marc Boon 08 Nov '04

08 Nov '04

Is it possible to use [makefilename] and [open $1] to open files whose names contain spaces? I tried quotes, but they are simply copied literally to the filenane, and any space breaks the message. Any suggestions?
