Re: [PD] Updating Pd-Extended
by sebfumaster＠aol.com 05 Mar '15

05 Mar '15

It seems that the main/only thing to do in order to update the Pd-extended core is to update vanilla to incorporate the GUI rewrite stuff, as well as closebang and initbang (what other things?). It seems that someone just needs to go through and copy all of the code directly, deciding which GUI things to keep and which to discard -Sebastian

Updating Pd-Extended
by João Pais 05 Mar '15

05 Mar '15

Hello list, I wanted to ask, what is the current state of the pd-extended distribution? Pd-vanilla has had some regular updates recently (some of them with interesting developments), but the latest pd-ext version is still from almost 2 years ago. Best, jmmmp

Is there a way to get the canvas my object is at runtime ?
by Antoine Villeret 03 Mar '15

03 Mar '15

Hi, I would like to retrieve at any time the pointer to the t_canvas containing my object. Is that possible ? I know I can retrieve it with something like : t_glist *glist=(t_glist *)canvas_getcurrent(); t_canvas *canvas=(t_canvas*)glist_getcanvas(glist); in the myobject_new() method. But the same give me a (nil) t_canvas pointer outside the new() method. Thanks in advance. Antoine -- do it yourself http://antoine.villeret.free.fr

Gem render out of the screen (and v4l2loopback)
by Olivier Baudu 03 Mar '15

03 Mar '15

Hi list, Until now, and as far as I (think I) can remember, GEM was rendering frames even if the window (with or without border) was : - out of the screen - reduce in the tool-bar - hidden by an other window The last time I use this property was on an Ubuntu 13.10 both with "pd-vanilla + gem from the depot" and " pd-extended" (but I can't give you versions... because... well, I don't know them... sorry) On several different patches, I recorded GEM content (which was not display on my desktop because of "offset" option) with the combo [pix_record] / v4l2loopback in order to make a "fake webcam" to stream. It was working. It is still working on computers where those patches where installed. Now, I am on Ubuntu 14.04 / GEM: 0.93.3 and if anything is put over the GEM content, it seems to be that none of the pixel "under" is rendered. If I open the v4l2loopback device on VLC (or whatever) and hide part of the GEM window (even by dragging icons from my desktop), those parts are not refresh anymore. Does GEM change its way to render ? Is the Ubuntu 14.04 display different ? Do I misunderstood something ? Sorry if I'm fuzzy... If questions, I'll try to explain better. Thanks in advance for any help. 01ivier -- "On ne peut pas vivre dans un monde où l'on croit que l'élégance exquise du plumage de la pintade est inutile. Ceci est tout à fait à part.

Pd font logic
by Jonathan Wilkes 03 Mar '15

03 Mar '15

Hi list, Can somebody explain to me how font sizing actually works in Pd? I see a table of integer metrics in C, a table of integer metrics in tk, and some logic that find the smallest GUI font size that can fit the metrics in C. I assume that I must use the metrics in C if I want boxes to measure what they currently do in Pd. If I'm using Deja Vu Sans in Node-Webkit, what do I need to do in order to make the text fit correctly in the boxes? It seems problmatic because the actual font metrics as displayed probably won't be integers, but the current API doesn't let me send floats. -Jonathan

bandlimited wavetables for pd vanilla
by Claude Heiland-Allen 02 Mar '15

02 Mar '15

Hi all, Today I implemented bandlimited wavetables in Pd vanilla using the idea behind mipmapping in OpenGL (ie, generate many filtered and downsampled versions of a source, use the most appropriate version(s) by a function of the derivative of the lookup index). More info and full source (quick start tutorial: bl-example.pd): https://gitorious.org/maximus/pd-bl License: same as Pd vanilla. Advantages over other implementations: * Can generate wavetables from any waveform stored in a table. Disadvantages: * The higher harmonics are reduced compared to an optimal method.

Parse/split symbol by delimiters like - or _ ?
by JF 02 Mar '15

02 Mar '15

Is it possible to split a formatted symbol such as...drums_1.wav ...to extract the float '1' and use that to assign a meaningful attribute? For example a float could represent a loop playback switch. if I have 'drums_0.wav' I would like to extract the float, find that itis '0' and then I would know that this WAV file is say, not to be looped.Or if I had 'drums_1.wav' I would be able to parse the filename, find the '1'which I now know to loop the WAV file. Thanks in advance! John

high channel count audio output on the cheap?
by Chris Chronopoulos 01 Mar '15

01 Mar '15

Hi all, I've been looking for an inexpensive way to start playing around with the HOA library <http://www.mshparisnord.fr/hoalibrary/en/> from within puredata. But I've had trouble finding an audio interface with lots of analog outputs (16 or more) that doesn't break the bank. The most promising candidate I've found is maybe the Focusrite 18i20 <http://www.sweetwater.com/store/detail/Scarlett18i20>, but even that seems like overkill: I don't need inputs, or pre-amps, or MIDI or ADAT, just output. Anyone have any suggestions for a bare-bones, high-channel count DAC? Preferably with USB or PCI interface, preferably Linux compatible? Thanks in advance, Chris Chronopoulos
