libpd and Unity
by Varun Nair 07 Mar '14

07 Mar '14

Hi all, I extended Patrick Sebastien's work in libpd-4-unity on Windows and now have it working on OSX and Android. iOS is pending but will happen soon. The whole API hasn't been tested, but basic functionality is in place and works. More info here <http://twobigears.com/labs/unity-and-libpd/>. Feedback and bug reports are welcome! Best, Varun -- @ntkeep <http://twitter.com/ntkeep> re-sounding.com <http://re-sounding.com> designingsound.org <http://designingsound.org>

Pd sample rate and audio interface
by Burkhardt Reiter 06 Mar '14

06 Mar '14

Hi, General (Pd-101?) question about how Pd talks to the audio interface for sample rate agreement. On my system - OS X 10.9, Komplete Audio 6 interface, pd vanilla 45.4 - I can set Pd to a different sample rate from my interface, yet not achieve the expected transpositions from having unmatching sample rates. Within Pd, I have soundfiles recorded at 24, 44.1, 48, 88.2, 96, and 196 rates. When I set Pd to a sample rate other than the rate of the recorded file, the playback transposes as expected from the differing sample rates...i.e. the 44.1 file plays back at a higher frequency when Pd is set to a sample rate > 44.1. What I was expecting was that if I deliberately unmatch the sample rate of my interface and Pd, that the sonic output would be similarly transposed due to the sample rate in-equality. However, it seems that I can set my interface to any sample rate, set Pd to any sample rate, and the sonic output will be stable - a 440 osc~ will sound like a 440 osc~ - rather than transposed as stated in the Pd documentation section 2.4.1. I get the same stable results when Pd is set to output via my iMac's internal sound processor, too. I was hoping to use the unmatching sample rates between software and hardware as way of illustrating the necessity to have the sample rates match. Thoughts, suggestions, or clarifications? Thanks, br

pix_buffer loaded event
by Martin Eckart 06 Mar '14

06 Mar '14

Hi all, I'm loading a series of images into a pix_buffer using folder_list and [open( messages. I would then like to send a bang event once all the images are loaded. 1) Is there a way to find out when pix_buffer has finished loading an image? Maybe pix_buffer_write has something? 2) Is there a way to know when folder_list has finished outputting all the files? This seemingly easy problem has me scratching my head. The best workaround I can think of at the moment is to just build in a long enough delay before triggering the finished event but that feels like a dirty hack. Thoughts? -martin

PdParty: name change ideas?
by Dan Wilcox 06 Mar '14

06 Mar '14

Howdy all, I will begin the process for releasing PdParty on the iOS App Store pretty soon. I was thinking that if I ever want to change the name, I need to do it now. When I started, PdParty was mainly a port of PdDroidParty. Now, it's become something more and I'm thinking of a new name for a different identity. Don't get me wrong, PdParty is already a pretty good name and I may keep it, but I'd like to brainstorm anyway. Any suggestions? -------- Dan Wilcox @danomatika danomatika.com robotcowboy.com

Re: [PD] Bugs in Pd-Extended in Ubuntu LTS
by Pierre Massat 06 Mar '14

06 Mar '14

Hi, Just a quick follow up on this topic. I have just compiled Miller's latest version (0.45-4), and the bug that's crashing X is still there. This time I managed to reproduce it somehow by creating an empty object to make a subpatch and typing "pd m" (and bang it crashed). Same behaviour with the same patch in pd-extended 0.43.4. It's super annoying...

Pd as sound editor (issue with "scrolling" a table) ??
by Pierre Massat 05 Mar '14

05 Mar '14

Dear list, I am working on a small patch which stores simple events in a table to trigger sounds later on. I would like to be able to edit the content of my table easily, which requires scrolling it, zooming in, and eventually editing the content. I have found away of scrolling the content, but it is very slow with relatively big tables (hem, even with a table with 20 000 samples...). Please see the example attached. I have 2 questions : 1) Is there a more efficient way of doing this ? Copying only part of the content is worse (i've tried). 2) Can I prevent the content of the table from spilling over the table to right of the left ? I get the same behaviour in a GOP, and putting a canvas next to the table to cover it doesn't work because the table content gets redrawn on top of it. This leads me to a more general question about something i've found in the help : "5 Wave editing: with proper manipulation of array data, Pd can be fully functional wave editor, complete with mouse-clickable cut-n-paste, pitch-shift, time expansion, down/upsampling, and other tools typically found in commercial wave editors." This has always sounded very appealing to me, but i wonder how realistic this statement is... unless i'm ignoring 80 % of what can be done with tables in Pd. Cheers, Pierre.

jack and callbacks
by Peter P. 04 Mar '14

04 Mar '14

Hi, just learned that my Pd vanilla Pd-0.45.0 from Miller's Git sources works "much better" (less drop outs, etc) under jack when enabling "use callbacks". Is there a way to enable this worthy parameter from the command line? Perhaps a way of setting it statically, maybe in s_audio_jack.c ? Thank you and enjoy! Peter

Get name of patch from within the patch
by Kaj Ailomaa 04 Mar '14

04 Mar '14

Hi. I've been googling a bit and looking through the library of objects that comes with pd-extended, but can't seem to find a way to get the name of the patch from within the patch. Anyone know of a nice method to do this?

[PD-announce] [Workshop NYC] The Xth Sense: make your own biophysical wearable for interactive sound and video
by Marco Donnarumma 03 Mar '14

03 Mar '14

[apologies for x-post] REVERSE is thrilled to announce a unique, one weekend workshop to be hosted at our space on Saturday March 8th and Sunday March 9th. The Xth Sense: Making your own Biophysical Sensor is a hands-on training in augmentation of the body for musical performance. The Xth Sense (XS) is a DIY biotechnological musical instrument that amplifies the muscle sound of the human body, and use them as control data and musical material for interactive performance. It is open source and it was named the "world's most innovative new musical instrument" by the Georgia Tech Center for Music Technology (US, 2012). WHEN: Saturday March 8 and Sunday March 9, between 1-6 PM WHERE: Reverse Space, REGISTRATION: $300 REGULAR - $270 STUDENT (WITH ID) * Sensors are included The workshop will be limited to 12 participants. More info and registration at: http://reversespace.org/the-xth-sense-making-your-own-biophysical-sensor/ Developed by performer, body tinkerer, biotech creator and writer Marco Donnarumma, this two-session workshop will teach participants how to build their own XS sensor from scratch and how to generate visceral music and control live videos using the muscle sounds of their bodies. http://res.marcodonnarumma.com/projects/xth-sense http://marcodonnarumma.com/bio/ The XS amplifies the muscle sounds of the human body, and use them as control data and musical material. When a performer contracts any muscle low frequency sounds are produced. By capturing these sounds with the XS microphone sensor and live sampling them with a computer visceral music is generated in real time. It's like connecting a guitar to an effect pedal; but here is the body to be connected to an adaptive computational system. One has complete control over the sound shape by simply contracting muscles in different ways. No previous experience in electronics or programming is required, however participants should be familiar with digital music creation. At the end of the workshop, attendants will be able to keep the XS biosensors they built, and the related software for their own use. -- Marco Donnarumma Performer, body tinkerer, teacher and writer. #soundandmusic #biotech #freeculture EAVI - Goldsmiths, University of London ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Portfolio: http://marcodonnarumma.com Research: http://res.marcodonnarumma.com _______________________________________________ Pd-announce mailing list Pd-announce(a)iem.at http://lists.puredata.info/listinfo/pd-announce
