Electroacoustic songs with PD
by Joe Newlin 08 Jul '13

08 Jul '13

Hey all, I just released a 3-song EP (and they are indeed "songs") entirely recorded/synthesized/performed in PD: http://joenewlin.bandcamp.com/album/everything-is-shimmering-under-the-surf… I arranged the the pieces in Audacity, just to be consistent in using open-source tools from start to finish. I think it sounds a little different from what you might expect from PD - in fact, at a patching circle a while back a PD guru called one of the songs "lowbrow." Lower your brows, then, and listen! Thanks to everyone whose patches & ideas I used or was inspired by. http://joenewlin.bandcamp.com/album/everything-is-shimmering-under-the-surf… -- www.joenewlin.net www.twitter.com/joe_newlin

Where is vanilla's makefile and other stuff located?
by Alexandros Drymonitis 07 Jul '13

07 Jul '13

Hi, I've been trying to install Pd vanilla on Ubuntu 12.04 together with Pd-extended. I think I've created some mess as there are symbolic links pointing at other symbolic links pointing at pd-extended. Even though I thought I hadn't managed to install vanilla, I realised it's sitting in /usr/bin/ as puredata. In /usr/lib/ there is a pd/ directory which includes a doc/ and a extra/ directory, but these two directories have only Gem stuff, no [bonk~] or [fiddle~] or [expr~] (even though I can create all these objects). I have a vanilla version is OS X and in /Applications/Pd-0.44-0 there is the Contents/ directory where all the necessary stuff lies (Resources/extra etc.). Anyone knows where all this stuff is sitting in Ubuntu? Thanks

convolve two arrays into a third
by Tim 07 Jul '13

07 Jul '13

Hi, I am looking for a way to convolve two impulse responses stored in two array offline (i.e. not strictly real-time) with each other into a third array, to combine the effect of both into a single convolution operation in real-time. For MaxMSP there is a great tool by the University of Hudderfield called the "Impulse Response Toolkit" as part of the HISSTools, which can do exactly that. I was wondering if there is a port to PD or something similar out there. Thanks!

Sampler buffer?
by FernandoG 07 Jul '13

07 Jul '13

Hello I need to build a sampler patch for live performance where you can load lots of samplers. I actually use soundfiler and tabread but anytime i open a new file the sound is stoped, cut, by a moment. Is there any kind of buffer that let me choose and open samplers during the performance without this problem? Thanks a lot! f

PMPD how to get constant distance between two masses
by Patrice Colet 05 Jul '13

05 Jul '13

Hello, I'm trying to find a setting for linking two masses that have always constant distance, but couldn't find how to do it, the link is always resizing like a rubber instead of being solid like wood. I guessed that fixing K to an high amount would make a solid link, but this is breaking it instead. The purpose is about applying forces to a cylinder represented by two masses and a link to make it rotating. Colet Patrice

Extended view toolkit: texture coordinate
by Husk 00 05 Jul '13

05 Jul '13

Hi Peter and list, I finally had time to explore extended view toolkit and it's really working well...congratulations! There is something still I miss: how the texture coordinates works. What units do they uses? How do I relate one projection panel to another to share content between them? Let's say I want to add a floor to your 04_ev_example_3d.PD: what coordinates I should put (for example) to connect the floor with the left projection panel?

Libpd running in OS X app
by Joe White 05 Jul '13

05 Jul '13

Hi guys, Does anyone have any experience running libpd in an OS X app, using CoreAudio. I'm able to run a patch and receive print statements but I'm not getting any audio output and DSP doesn't seem to be processing. I created a quick test tone in code to see if it was my audio unit but that works. My main problem it seems is that after calling [PdBase processFloatWithInputBuffer:leftBuffer outputBuffer:leftBuffer ticks:ticks]; ...the buffer is still empty. Anyone have any ideas? I'm calling [PdBase computeAudio:] just before I start the AudioUnit. Here's the whole controller class if that helps: http://pastebin.com/eYf1Facp Any help would be much appreciated! Many thanks, Joe -- Follow me on Twitter @diplojocus

CPU 100% after suspend (was Re: closed window not destroyed? (in l2ork))

I was actually toggling DSP on and off, because I usually keep it off. When I switched it on, CPU usage instantly dropped to normal. Seems like a symptom that is avoidable... András

GOP text field / symbol which is resizeable? (was: GOP text field which sends bang?)
by András Murányi 04 Jul '13

04 Jul '13

I'm reformulating my question as the problem is evolving: do we have an object that - Displays and holds a text value (like Symbol or Message box), - is Graph-on-Parent, - can be resized (like Number2)? (or small enough by default?) Something like a Number2 for symbols...? Or a settable comment...?
