expr possible bug
by Jamie Bullock 12 Mar '05

12 Mar '05

Hi, I don't know if anyone can confirm this, but there seems to be a strange behaviour with expr. I checked the archives and couldn't see anything obvious, so apologies if this is a repeat. If used in an abstraction and given a $x variable as a first argument i.e. expr $1 * $f3 * 10 it works properly - substituting $1 from the abstraction's first argument. However, if the first argument is delimited by parenthesis i.e. expr ($1 * $f3 * 10) the console reports a syntax error and an instance of the object is not created. This is no major problem, but I just thought it should be reported. Jamie

segmented patch cords - tunnel?
by Thoralf Schulze 12 Mar '05

12 Mar '05

hi there, regarding the segmented patch cords: imo, this feature would greatly enhance the readability of complex patches if there's a lot of messaging going on. I would propose the idea of a 'tunnel'-object, which would be a container holding several patch cords at once (like a wiring harness). the tunnel itself is segmented - it could be drawn in a way similar to how you draw masks in image processing apps (click [start] - click [point] - click [point] - doubleclick [end]). to make a connection between two objects using the tunnel, one would click at the outlet of the first object, then at the tunnel and finally at the inlet of the second object. this comes in handy for connecting 10 outlets of an objects in the upper right corner of your patch with a thingie in the lower left. I realize the the same result could be achieved by muxing the signals and/or using local sends and receives. however, muxing might not always be feasible, and the latter is imho an inferior solution in terms of readability ... the problem in implementing this will be backward compatibility. maybe the tunnel could be implemented as a generic pass-through - object, so that it would appear as outlet -> cord -> tunnel -> cord -> inlet to older versions of pd. future versions might be smart enough to recognize the tunnel for what it is and draw the patch accordingly. just a few thoughts, thoralf. ___________________________________________________________ Gesendet von Yahoo!

Now if arrays would opperate correctly on 64-bit I would be where you all are now, as far as working PD software goes... Thanks again! -thewade

Web Interface w/ PD
by Ian Smith-Heisters 11 Mar '05

11 Mar '05

A couple thoughts I had about web interfaces for PD.. Has anyone looked at this? http://www.x-desktop.org/ Some guys did up a frontend for eGroupWare using this and it looks killer. Is it too clunky for Pd? Also, has anyone written a CGI interface to Pd? It strikes me that it would be very easy to write, eg. parse a pre-written patch and allow the user to interact with it. Maybe no edit mode. Okay, I really do need to stop finding excuses to not finish my final exam. -Ian -- http://www.0x09.com

Re: [PD] new pmpd developer

hello thomas, ok, you're right, there is only few very simple exemple of pmpd. but in fact, i think all pmpd exemples are simple :-) but yes, you nead to have a good knowledge of pd / gem before tring pmpd. making more simple exemples is not really on my todo list. but if someone make some, i'll be very happy to add them on the exemple set. :-) Nicolas should focus on other aspect of physical modeling. mainly the integration with pd (and datastructure). anyway, i'll also be very happy if you can upload somewhere video, sound or images of your instalation. thanks Cyrille Thomas Ouellet Fredericks wrote: > Excellent! > I worked with pmpd and it is great. > Here is a first comment : make more simple examples before the complex > ones, like two masses and one link (with everything visible in Gem). > Pmpd is VERY hard to learn, but VERY powerfull (the interactions is > even harder). > I have an installation running with pmpd and will post the code if > there is interest. > > > Tom > > > On Fri, 11 Mar 2005 15:22:44 +0100, cyrille <cyrille.henry(a)la-kitchen.fr> wrote: > >>hello, >> >>thanks to La kitchen and Ircam, Nicolas will work on pmpd for the next 4 >>mounths.

Re: [PD] and supercollider

vincent rioux: > >i can vaguely remember that i saw a pd object related to sc >but cannot find anything about it anymore >any idea? > Perhaps you are thinking about the k_sc~ object I once made that let you get access to supercolliders input and output channels? I removed it from cvs and replaced it with the more general object called k_jack~ . >otherwise does anybody know any references which demonstrate their >combined use (thanks to osc i suppose). I did a project doing the combination of supercollider and pd for DSP and guile for controlling it all. Heres the project report (max 10 pages. :-): http://www.notam02.no/~kjetism/mus2860/doc/eksamen_en.pdf And all files (code and soundfiles): http://www.notam02.no/~kjetism/mus2860/everything.tar.gz

Resonant LP,HP,BP filters?
by Phillip Stearns 11 Mar '05

Wondering what's out there in the way of resonant filters with similar operation as the [vcf~] as far as audio rate controllable center frequencies goes. Thanks!

by et 11 Mar '05

11 Mar '05

hello, I have an array in a patch that I need to use multiple times, [table $0-array] ... I want to resize that array [56] | [;$0-array resize $1] doesn't work because the $0-array is not interpreted as an array name.... is there a workable way to resize an array named with $0 ? Etienne
