mrmr + iphone + pd
by mark edward grimm 07 Sep '08

07 Sep '08

hello, i just noticed that cydia offers 'mrmr' on the 2.0 jailbroken iphones. i never tried it on the old 1.1.4 firmware so im not certain how to connect the iphone to pd. im on osx 10.5. is there a tutorial on how to make the connection to send osc? i have not been able to locate.... ...other than this hard to see youtube vid: http://www.youtube.com/watch?v=RDtdxVJXn-E&feature=related anyway... here the link to the mrmr site: http://poly.share.dj/projects/#mrmr and the pd patch stuff: http://pissypaws.tumblr.com/post/33502398/pdipod-mrmr-to-pd-on-iphone-ipod-… step-by-step guide maybe? thanks! mark

GEM on mini computers: micro/nano ATX
by simone-www.io-lab.org 07 Sep '08

07 Sep '08

hi i d like to embed a GEM based patch in a mini computer such as a micro ATX or similar. Is there anybody who had any experience using low power machines with GEM? any specific model? Any minimal requirements for CPU/GPU ? So far i understand that the GPU needs to have drivers for 3D acceleration and OpenGL Thanks Simone -- .wmv , .wma , .pps along with all proprietary Windows formats won t be accepted and/or viewed....

Setting a variable in abstractions
by simone-www.io-sound.org 07 Sep '08

07 Sep '08

hi this is my first patch so bear with my n00bness I ve taken a screen shot of the whole thing open: it s a GEM patch that will show 8 "knobs" and rotate them depending on the MIDI cc input. and also show the cc value. So far i ve created the 8 knobs but i can t really understand how to send the MIDI cc from "handson2" to the abstraction "handson" and parse it to the right knob.

earplug~ or FIR~ for HRTF?
by Claude Heiland-Allen 06 Sep '08

06 Sep '08

Hi all, I'm considering whether to use the earplug~ HRTF external or some alternative implementation of binaural spatialization. On the plus side, earplug~ seems quite easy to use. On the down side, earplug~ seems not to handle any sample-rate stuff at all, so I'm wondering which samplerate the impulse responses in the earplug_data.txt are sampled at (because obviously it would be somewhat weird to use them at another rate...). I don't really need the interpolation provided by earplug~ either, so I guess I could save some CPU by using FIR~ directly, but then I need to obtain some HRIR's (ideally both at 44100Hz and 48000Hz sample rates). So: has someone already made a binaural processing patch using FIR~ and some set of impulse responses and would care to share it? Some context for the curious: I'm trying to auralize 4D space using 4D room simulation, with an "ear" made up of several co-solid listening points in the 4D space, each mapped to a 3D source point for binaural processing. Thanks for any tips, Claude -- http://claudiusmaximus.goto10.org

old and new
by marius schebella 06 Sep '08

06 Sep '08

hi, just wanted to post two links. one is a <2min documentation of one of my school projects from last year http://www.vimeo.com/1673188. The other one is a work in progress, maybe some people want to comment on(?). I got intereseted in analyzing Pd patches and later want to create new patches based on this information using genetic algorithms. My plan is to store the probabilities of position, connections and breed and evaluate the created patches (something like that). I found 37600 pd patches on my hard drive, which gave me roughly one million objects (989260 to be exact). Plotted the positions of some of the objects in Gem, showing the local spatialization (in pixels). For example of the one million objects there are 2882 phasor~ objects, 1062 adc~, 5528 dac~ and 3001 gemwin objects. Just started with data mining, but guess this will be fun! http://www.parasitaere-kapazitaeten.net/pd_stats marius.

Third RjDj Sprint, September 19-21 2008, Vienna
by Paul Brossier 05 Sep '08

05 Sep '08

Hi PD list, Here is another invitation to a three days PD hacking marathon, this time in Vienna. Best, Paul = RjDj Sprint, September 19-21 2008, Vienna = Musicians, composers, coders, PD people and everyone interested in RjDj are invited to come along in Vienna. http://www.rjdj.me/viennasprint2008/ This time we have some interesting people from the vienna music scene as well as several participants from the previous sprints. If you missed these two, check out our website and the previous announcements. [0][1] = What is RjDj? = RjDj is an interactive music format for iphone and other mobile devices. The goal of the project is to turn interactive music into a consumer format. More info at http://www.rjdj.me. = Open doors = RjDj is built on a number of open source components and most parts of the project will be open sourced in return. RjDj tracks are composed using pure data (PD). The RjDj player has direct access to the online repository of RjDj tracks. Of course we want as much people as possible to participate in this and create RjDj tracks. = RjDj sprint = In this sprint we are still focusing on creating new tracks for RjDj. Several musicians and composers from Vienna will join, as well as participants from the previous sprints. For this third sprint we are looking for about 5 more PD people. = Joining the Sprint = Your feedback will have direct impact on the development of the RjDj format, player and composition tools. If you think you should join us in Vienna, let us know, now! People in or around Vienna would also be very welcome. If you want to join, send us a mail to info at realityjockey.com. = Online = If you can't make it to Vienna, you will still be able to be part of the sprint by joining in the #rjdj irc channel on freenode. Thanks, The RjDj Team Michael Breidenbruecker, GÃ¼nter Geiger, Amaury Hazan, Paul Brossier [0] http://lists.puredata.info/pipermail/pd-announce/2008-07/001280.html [1] http://lists.puredata.info/pipermail/pd-announce/2008-07/001287.html

[PD-announce] Update
by B. Bogart 05 Sep '08

05 Sep '08

Hey all, In case you have been wondering what I have been doing for the last two years, here it is conveniently packaged into a Masters Thesis. My application has been officially accepted. I'll be spending the next year working on a Canada Council production grant while I think about where I would like to do a Ph.D. http://www.ekran.org/ben/Ben-Bogart-Thesis.pdf More images and a video are available at: http://www.ekran.org/ben/wp/?p=227 I hope all is well. I have not heard from you in some time. Please drop me a line to let me know what you are up to. B.

It does not have sys_register_loader() visible externally which I think in another discussion, Hans had mentioned he had patched for extended. At least the symbol to that function was not found neither in pd.dll nor pd.lib attached to Vanilla. -- David Shimamoto

Number box and CPU load
by Mika Ristimäki 04 Sep '08

04 Sep '08

Hi all, I have a one quick question about number boxes and how they effect CPU load. I use number boxes quite a lot for debugging and sometimes I forget to remove them from the final patch or abstraction. So I was wondering do the number boxes cause significant CPU usage even when they are not visible? For example when the abstraction window with the number boxes is closed? -Mika
