Re: [PD] How to reduce CPU use on unused subpatches-abstracts?
Hi Mario, There is a thread somewhere about connections vs. s/r throw/catch, don't have time right now to search for it, but I'm sure it is there. If I remember correctly the overhead is not that big and you don't want to be connecting all that stuff by hand. In any case, there are other things to look for. If you are using graphics objects, or objects like env~ you might want to bring down the refresh rate. Are there any [metro 1] or similar objects lying around which you might have forgotten about? Do you have a lot of GOP? I am not sure this is entirely relevant, but it might be worth researching... Also, control operations do take some cpu. do you have a big control layer? J Thanks, Roman, but I'm already using [switch~] inside each FX, to stop processing the signal. I learned it some time ago, from here: http://puredata.hurleur.com/viewtopic.php?pid=35939#p35939 But I think that [receive~] and [throw~] are still using CPU. I didn't try to use inlet~ and outlet~, because I have to make 400 conections at hand... that's why I asking first. If it will work, I'll do it (or find a way to automatically do it) El 05/08/13 09:29, Roman Haefeli escribió: Hi Mario Check [switch~] and its help patch.

I'm considering a project with it though, where I would like to use Pd to generate some audio, and to output it to another device (a Mutable Instruments Shruthi synth filter board). However, I also need to generate control voltages that need to get sent to the filter board, to control its various parameters (e.g. cutoff, resonance, etc...). I also need to send +5v and ground to the filter board. So from your post, it seems quite straightforward to be able to access the GPIO pins from within Pd. But I need to be able to create variable voltages (between 0 and 5v) on those pins. In the post above, you mentioned that you send a float to the gpio object to write a value to the pin - would sending a 0.5 for example give me 2.5v on the pin? Or is it only on/off (0 or 5v)? If the former, I'm all set! If the latter, I'll need to figure out how to simulate a reduced voltage at the pin (likely using PWM or something – but I'm not really sure how I would do that…) Any help greatly appreciated!

Through these tutorials, the readers can learn how to program metronome, synthesizer, sampler, granular sampler, drum machine, various time-domain and frequency-domain effects, presets, data structure and so on.. The second part introduces 6 advanced ways to use Pd employing external software and devices, such as Arduino, iPhone, Logic... It also explains how to use GEM, how to connect multiple Pds over the network, and how to program your own objects in C language with XCode. The third part is the object dictionary, covering almost all Pd-vanilla objects with simple example patches Furthermore, the book includes interviews with three active artists using Pd for their projects. You can pre-order the book now on amazon Japan the price is 4,725 JPY. http://www.amazon.co.jp/dp/486267142X The TOC and 12 sample pages are available on the website of the publisher. http://www.wgn.co.jp/store/dat/3244/ best regards, === Dr. Chikashi Miyama Adjunct Instructor, Music College of Music and Dance, Cologne Germany ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list -- -- __/__/__/__/__/__/__/__/__/__/__/__/__/__/__/__/__/ Seiichiro Matsumura s...@low-tech-ism.com http://low-tech-ism.com/ __/__/__/__/__/__/__/__/__/__/__/__/__/__/__/__/__/ ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

[PD] [OT] Latency?
10ms is around the human-ear latency, so anything at that level or below should be good enough for guitar/drumming Hi all, I did some research on this some time ago. You could check: The perception of cross-modal simultaneity by DJ Levitin, 2000 and Musical Effects of Latency by Mäki-Patola (as well as some of his other papers on latency) http://www.jyu.fi/musica/symposium/symposiumin_satoa_2005.pdf#page=83 There are of course many forms of latency, inter-aural ( 5ms), visual to aural, action to aural and so on. Actual numbers in milliseconds are generally obtained in laboratory conditions and are hard to apply in real-world cases. Different behaviors (or mappings if you like the term) have different perceived latencies. Furthermore, a quiet note in a piano can have a latency of 130ms (from when the key is first depressed until there is sound I believe) and we get away with it. The most important aspect of the levitin paper is that we have anticipatory mechanisms to compensate for latency. That being said, I've been playing live with Pd latencies (15ms+) for a while and have learnt to live with it and forget about them most of the time (there are limits of course...). best, J *** Jaime Oliver www.jaimeoliver.pe jo2...@columbia.edu Columbia University On Jul 27, 2012, at 9:48 AM, Simon Iten wrote: Well from a musicians point of view (me) everything above 8ms is not very playable.

Ircam (Institute for Research and Coordination in Acoustics and Music) offers experimental environments where composers/artists strive to expand their artistic experience at one end, and scientists aim at extending research and technological paradigms for new artistic expressions. Such interactive process is called Musical Research. For its fourth edition, Ircam and the INEDIT Project partners are inviting composers and artists to submit projects for the 2013-2014 Musical Research Residency program. The program is open to international artists, regardless of age or nationality, who wish to carry experimental research using Ircam's and partners' facilities and extensive research environment. Submission is online only and an international panel of experts including researchers, composers, computer musicians and artists will evaluate each project. Upon nomination, each candidate will be granted a residency at Ircam during a specific period (three or six months) and in association with a team/project at Ircam. In addition, laureates receive an equivalent of 1200 Euros per month to cover expenses in France.

[PD] [GEM] Re: question about contours and Pure Data?
Hey Mick, I'm copying the list as you might get interesting responses... in fact I am looking for a contour transform in PD. I come from Matlab image processing and I am confortable with the Image Processing form of approaching images, treating them like matrices, and applying Hit Or Miss transforms (are you familiar with this? and Mathematical Morphology?). Contour objects are not readily available in GEM as far as I can recall, but I am not an expert. A generic object to apply small matrices might be a useful thing to have though... how do you threshold a grey level image? check out pix_threshold not to make it too long, how do you find contours of a binary image? and is there some way to run a kernel (little matrix, i.e. 3by3) on an image, apply some processing inside this kernel (i.e. calculate the minimum and set its value in the center pixel) to transform the whole image? you can check out the code for pix_mano.cpp in the extra folder of GEM. I think this is the best way to analyze the contour of an image. It sounds like pix_mano, or parts of its code, may already be doing what you are looking for? best, J *** Jaime Oliver www.jaimeoliver.pe jo2...@columbia.edu Columbia University On Jun 15, 2012, at 7:09 PM, mick mengucci wrote: Hi excuse me if I write you I saw your email at the bottom of an interesting patch called [pix_mano] in fact I am looking for a contour transform in PD.

Re: [PD] [GEM] pix_external, OS X 10.7
Please ignore the previous message. I mixed up some files ... autogen.sh runs fine. pix_example compiles and loads fine now. However, it is a limitation that pix_externals need to be compiled with the same version of Gem. This prevents combining two binaries compiled with different versions and therefore makes it harder to share. Or perhaps the case is that it needs to have a specific version or older? In short, if someone wants to compile their own pix_external in OS X 10.7 as of gem 0.93.3, you need to: 1) download gem binaries for os x and gem source 2) Create a project in /extra just like the other projects there. 3) modify the config files as specified in README-EXTRA.txt 4) run ./autogen.sh 5) run ./configure --enable-fat-binary=i386 --with-pd=/Applications/Pd-0.43-2.app/Contents/Resources/ 6) cd into the project folder and run make 7) put the project folder in the path of Pd...
