Reset webcam properties
by Antonio Roberts 15 Nov '13

15 Nov '13

Hi everyone I set the properties of my webcam (saturation, hue etc) via pix_video/enumProps and now it's stuck like that, even if I restart my computer. Is there any way to reset the values to their original? Kind regards, Antonio -- ============================ antonio(a)hellocatfood.com http://www.hellocatfood.com ============================

waveform segment breakpoints
by Ronni Montoya 15 Nov '13

15 Nov '13

Hi, i need to convert some data into waveforms. I need to use the trick used in non standard synthesis where you use the data to define waveform segments breakpoints. Do anybody have tried something like this purely in pd (not externals)? which is the best way of achieving this in pd? cheers R.

realtime MIDI on Windows - best practices for efficiency?
by Joe Newlin 15 Nov '13

15 Nov '13

I have a big patch I use for realtime manipulation of live sound inputs. Often when adjusting pots and sliders on a USB MIDI controller, I get audio dropouts. I've tried putting all of the MIDI objects in a separate patch running in another instance of PD, polling the inputs at intervals using [mapping/resample] to reduce the amount of data being sent, and sending the data over OSC to the main patch. I've killed as many other processes as possible. And I still get dropouts. What could I be doing wrong? This is 0.43.4-extended on Windows 7. Thanks, Joe -- www.joenewlin.net www.twitter.com/joe_newlin

pd 0.45 [getdir] equivalent?
by Dan Wilcox 14 Nov '13

14 Nov '13

Howdy, Forgive me if I haven't kept up with the Pd 0.45 improvements, but is there/will there be a vanilla mechanism to get the full path of the current patch/parent etc? Basically, I'd like to be able to use the "pd open patch.pd /path/to/dir" open message in pure vanilla without hardcoding the path or relying on an external (ggee [getdir] does the job). As far as I know, there is no vanilla only way to do this, or am I wrong? -------- Dan Wilcox @danomatika danomatika.com robotcowboy.com

question on help patches path
by enrike 13 Nov '13

13 Nov '13

Hi I am giving a very short PD workshop soon and I want to give students a folder with some ready made examples. Within that folder there is a small library with some abstractions the examples use. Each abstraction has its own help file next to it. However right click > help on the abstraction objects of the examples does not open the help files because PD cannot find them. It only works if the library is located in the extra folder. This I want to avoid if possible. I have tried to add the path of my library with abstractions in the preferences but this does not work. Is there any other simple way to achieve this? thanks enrike

[PD-announce] The body vexed - Hypo Chrysos Action Art for Biophysical Media at CYNETART Fest
by Marco Donnarumma 13 Nov '13

13 Nov '13

(apologies for any x-post) Dear all, if you happen to be in Dresden this weekend. On Thursday and Saturday night I'll be at CYNETART Festival performing a new version of Hypo Chrysos, an action art piece for Xth Sense biophysical media, multiple loudspeakers and subwoofers, and real-time visuals. Info below. wishing you well, M \\\\\\\\\\\\\\\\\\\\\\\\\\ in occasion of Metabody Performance Night @ CYNETART Festival Hypo Chrysos v.2 action art for vexed body and biophysical media (Xth Sense) "During this twenty minutes action I pull two concrete blocks in a circle. My motion is oppressively constant. I have to force myself into accepting the pain until the action is ended. The increasing strain of my corporeal tissues produces continuous bioacoustic signals. The sound of the blood flow, muscle contraction bursts, and bone crackling are amplified, accumulated, distorted, and played back through 4 loudspeakers and 4 subwoofers using the biophysical instrument Xth Sense (Pd-based), developed by the author... When the performer’s muscle vibration becomes tangible sound breaching into the outer world, it invades the audience members’ bodies through their ears, skin, and muscle sensory receptors. The sound makes their muscles resonate, establishing a nexus between player and audience. The listeners’ bodies, the player’s body, and the performance space resonate synchronously" VIDEO: http://marcodonnarumma.com/works/hypo-chrysos/ WHEN: Thursday 14th November / Saturday 16th November WHERE: Dresden, Great Hall of the Hellerau Festpielhaus, Germany COST: Thursday £3, Saturday £5/8 PUBLICATION: http://cec.sonus.ca/econtact/14_2/donnarumma_hypochrysos.html Metabody Conference is part of the Metahuman/Metaformance Studies programme of the European Community-funded Metabody Project, that embraces the series of presentations taking part in more than 25 events in more than 15 cities of 11 countries.

Announce: new rjlib compatible rc-patches
by Dan Wilcox 13 Nov '13

13 Nov '13

Howdy all, I've begun the process of porting my patch library to compatibility with / reliance on rjlib and an overall less reliance on externals so they will work well with libpd & PdParty. In the spirit of "release early, release often", you can get it from github in the "rc" folder: https://github.com/danomatika/rc-patches/tree/master/rc Full disclosure: I've always turned cool examples from this list into abstractions and generally attribute the original authors. I also borrow some abstractions from other libraries in order to keep outside requirements low (mainly some from of the list-abs). Please let me know if I miss an attribution or if you don't want me to include an abstraction you've written. Highlights include: .................................... (I recommend the crossfm/pm/fmpm synths + GEM & trying Pd-extended + Billy Idol in c_midiplay-help!) c_autospigot - pass a signal only if it's above an amplitude threshold c_midiplay - midifile player (requires mrpeach [midifile]) c_nstep - arbitrary length bang sequence player c_playlist - manage a playlist from a text file c_qseq - sequencer interface to qlist c_spigot - toggle a signal without clicking e_3bandeq - dj-style 3 band equalizer e_moog - moog style resonant low pass filter (requires ggee) e_powdist - pow based distortion e_ringmod - ring modulation g_scope - simple oscilloscope gui g_spectroscope - frequency spectrum gui g_vu - mono vu meter g_vu2 - stereo vu meter m_ctlin - ctlin that can learn it's ctl num & channel m_fadtodb - convert fader scale to vu db m_mavg - moving average filter m_scalefilter - filter notes based on a given scale s_303 - roland tb 303 style bass synth (requires ggee) s_crossfm - cross frequency modulation synth s_crossfmpm - cross frequency / phase modulation synth s_crosspm - cross phase modulation synth s_sample - one shot sample player u_allnotesoff - send noteoff for all midi notes u_count - up/down counter u_demux2 - demultiplex from 1 inlet between 2 outlets u_list2symbol - convert a list into a symbol u_mux2 - multiplex between 2 inlets to 1 outleti u_openclose - open and close patches via filename (requires ggee) u_remote - send remote messages to state saving objects u_savestate - save & load scene state settings u_tabdump - dump the contents of a table as a list u_tabset - set the contents of a table via a list -------- Dan Wilcox @danomatika danomatika.com robotcowboy.com

how to install and use GPIO external
by Josh Downing 12 Nov '13

12 Nov '13

I'm trying to figure out how to use the [gpio] external and I'm totally lost on how to install it and then how to use it inside PD on my raspberry pi. I did download the external from Miller Puckette's website but that is about as far as I have been able to get. I would like to be able to configure 4 GPIO pins as inputs and read their state within my PD patch. Could anyone provide me with any help on how I would go about installing this patch and using it in PD on the pi? Also, I found a thread in the list serve archive where someone had attached a draft of instructions on how to install and use the GPIO external but unfortunately the attached file was not available. Could someone send me these instructions if you have them? Thanks, Josh
