metro drift
by Nicola Pandini via Pd-list 17 Jul '14

17 Jul '14

Hi, I made a patch that uses metro to keep the sync between sequencers and other instances of the patch. I also use this patch to start, stop and set the tempo of SooperLooper. I only use this patch to do MIDI stuffs (with options -noaudio -alsamidi) Sometimes, when the metro is running and I open a patch full of canvas and nbx, the metro freezes for a couple of seconds, and so Pure Data and SooperLooper lose the sync. Is there a way to avoid this? Will it be more stable if I start PD with -nogui and then PD -guiport 0? Thanks. -- Nicola

(GEM) JPEG rendering question
by David Schaffer via Pd-list 16 Jul '14

16 Jul '14

Hi there, I'm working on a jpeg glitch abstraction that has a GEM "preview" window: you do your modifications on the file and the (glitched) result appears in the GEM window just after the glitched file has been saved to disk. I'm noticing a substancial difference between the file displayed by GEM and the (very same) file displayed by aperçu (mac's default image viewer) or pixelmator for instance (The gimp seems to give the same results than GEM). I was wondering what causes this difference of rendering (different codecs ?) and if there was a way to control how GEM renders JPEG. I may also add that, when I open these files in aperçu, they seem to apear like in GEM, but, less than half a second later, the picture turns into something quite different, usually more colorfull and more interesting. Thanks in advance for your help, D.S http://www.flickr.com/photos/schafferdavid/ https://soundcloud.com/schafferdavid

Help for packaging pix_opencv
by Antoine Villeret via Pd-list 15 Jul '14

15 Jul '14

hello, I improved the build system of pix_opencv. The new build system uses automake tools. ./configure checks which module is available and then sets some flags to build or not some pd-objects at make time. This works on Ubuntu and MacOSX. Now I would like to make both binary archive for Mac OSX and package for Debian like system. What's the best practice to do that ? I've read the doc [1] but since my build system doesn't use the LibraryTemplate, I can't apply it. Should I reproduce the make rules it describes ? or is there another way to do that with some useful commands ? Thanks in advance Antoine [1] : http://puredata.info/docs/developer/LibraryTemplate

Raspberry Pi B+

Hi List, Anybody played with the new Raspberry Pi model? It claims to have improved audio; I'm curious how that would effect a running instance of Pd on the Pi. Best, Jonathan

peek at a pd object's data
by Jonathan Wilkes via Pd-list 11 Jul '14

11 Jul '14

If I have a t_gobj* for an object on a Pd canvas, and I know its size, how would I go about returning a list of bytes for that object's struct? I'm sure this is nearly useless because of pointers and padding, but it might be fun. Best, Jonathan

canvas_makefilename() returns error
by Jaime E Oliver via Pd-list 11 Jul '14

11 Jul '14

Hi all, I am trying to use the canvas_makefilename() function in g_canvas.c I am calling it like this: static void lilypond_write(t_lilypond *x, t_symbol *s) { char buf[MAXPDSTRING]; canvas_makefilename(x->x_canvas, s->s_name, buf, MAXPDSTRING); } but when I send the object a message such as [write test.txt( or similar, I get: error: consistency check failed: canvas_getenv Bus error: 10 The method is set up like this: class_addmethod(lilypond_class, (t_method)lilypond_write, gensym("write"), A_SYMBOL, 0); Anybody has any suggestion? best, J PS Sorry for pestering everyone with this, but there is little documentation on some of the functions in Pd. Perhaps this thread belong in the Pd-Dev list?

Getting the size of a file
by David Schaffer via Pd-list 08 Jul '14

08 Jul '14

Hi list, I'd like to find out a simple way to get the size of a file, be it a .wav, .mp3, .jpg, .mov. I thought about using binfile, but I can't find a way to use the second outlet's output (the one that sends out the info I'm looking for...). It doesn't seem to be a symbol... Any hints? Thank you all for your help, D.S http://www.flickr.com/photos/schafferdavid/ https://soundcloud.com/schafferdavid
