Re: [PD] How do I squeeze more performance out of Gem?
hello, i'm glad you find the bottleneck. but that's what i was afraid of : 2 side lighting are baddly suported on new nvidia hardware (at least on linux). (i mean : it's not only on my computer. it use to work fine). But you should be able to get the same lighting with this option. this option only force to compute color 2 time per pixel : not only for the visible face, but for both face of the object. So, if you got different lighting result, you just have to reverse some light orientation. i never test performances optimisation using shaders for light. cheers c Le 10/03/2011 06:20, John Harrison a écrit : Ok so I did something stupid with the [GEMglLightModeli GL_LIGHT_MODEL_TWO_SIDE GL_FALSE] test which that I connected it to a [gemhead] instead of [gemhead 1]. When I corrected that I did find that indeed the performance changes drastically for the better. OTOH I couldn't get satisfactory lighting for my environment. It's a good technique for me to remember and I could probably make it work even for this project with enough experimentation of lighting sources and direction but... it seems clear to me on my system at least with GL_LIGHT_MODEL_TWO_SIDE set to its default GL_TRUE the bottleneck is the lighting and any gains with a display list or model are lost because of the lighting issue. However I'm finding that I get satisfactory performance and appearance by changing the sphere to have 10 segments instead of 30. With a 10 segment sphere I can make 1000 spheres and straight-line curves at 20fps at about 70% draw on a CPU core. That works for me! :-) I was curious if for a future project there might be a way I could make a shader that would emulate the local lighting effect and do it more efficiently. Serious exploration with shaders definitely needs to be in my future. In any case, thanks for all the help! -John On Wed, Mar 9, 2011 at 1:55 PM, cyrille henry c...@chnry.net mailto:c...@chnry.net wrote: with lighting on, things did not really change with the model or display list, but rendering sphere is 2 time slower. here is the sphere.

Re: [PD] Patch for Akai EWI (was Reading and writing binary files)
Hi David, just out of curiosity I checked the dump requests in order to see if there is any reason for transmission of these NRPN controllers. There is absolutely no reason for them! I've attached my updated SysEx chart for the EWI-USB in case you want to mess around with anything. BTW the NRPN controllers are only being sent when there is a dump request from the Aria software to the EWI. Not when data is being sent to the EWI. After the dump is transmitted to the EWI the software sends another full (3 part) dump request and everything on page 1 of the chart is repeated. To me it looks like Plogue - who wrote the software - simply forgot to take out the NRPNs. This got me confused in the beginning, too. It's just a general problem when people like ewi-usb.com put some incorrect information on the web and don't correct this information anymore after it turns out to be wrong. Then guys like you and many others get confused. Ingo -Ursprüngliche Nachricht- Von: David [mailto:dfket...@gmail.com] Gesendet: Mittwoch, 9.

It looks like it went to: http://www.klippel.de/nc/know-how/literature/papers.html?sword_list[0]=papersword_list[1]=speaker Greetings Am 16.10.2010 06:46, schrieb Martin Schied: Hi! I'm no speaker modeling expert at all, but I can try to describe what produces sounds in an overloaded speaker. There are various sources of distortion, symmetrical (mechanic suspension) and asymmetrical (magnetic field) and also time variant (temperature) and modulation (doppler effect / amplitude modulation) effects. I don't know which effects have a stronger or weaker influence, but I describe what I imagine: High peak amplitude, positive wave: speaker moves to the front, parts of the coil will not be in the magnetic field anymore. The field isn't zero outside the magnet gap, but I guess it decreases rapidly and is almost zero (so for example if half the coil is inside the magnet, the parts outside will not produce a force. So the force is only half as strong as it should. For simplicity you could say the field outside the magnet's gap is zero, so you have a linear function of excitation / current. Also If the coil moves out of the field its impedance will decrease which has influence on frequency response for higher frequencies a bit. Heat If the impedance is reduced as described above, a higher current will flow and heat the coil more than usual. The resistance of the coil will increase when it gets warmed and thus the efficiency of the speaker decreases (up to -7 dB I read somewhere, but this wasn't meant for almost dead speakers but heavy load). The heat needs some time to dissipate, so some kind of slow pumping compression effect occurs. High amplitude, negative wave: The speaker's coil might crash into the magnet and create different mechanical noises. Also the speakers diaphragm will be deformed by this crash and create various kinds of noise. Additionally it carries the noises the coil created - depending on the material and shape this sound different (paper, Kevlar, aluminum, etc sound different). If this crash doesn't occur (professional speakers don't have this issue usually) the negative wave will not be distorted too much and maybe distortion can be ignored. In both directions the spider (basically a spring) starts to become nonlinear. Different manufacturers have different curves, but for small amplitudes they all pretend to be linear - so some experiments with sin~ or tanh~ might do it here. Then generally there are happening doppler-effects on all speakers with big excursion. You could model them through a variable delay, modulated by a differentiated, low pass filtered signal (don't bite if I'm wrong, it's already very late... ). Amplitude modulation can be applied the same way (lowpass and apply it to higher frequencies). so to sum it up: apply symmetric distortion for the spider, split the path into positive and negative parts, for positive samples: tanh~, polynomials or other wave shapers, for negative parts let the signal untouched or add noises of a crashing coil (don't know how to achieve this), then sum both signals up, apply doppler effect, amplitude modulation and pumping compression. perhaps that sounds like your speakers then :) I'm not sure if this works at all, but it definitely will sound very distorted in the end. did you already discover http://www.klippel.de/pubs/papers.asp ? cheers Martin On 15.10.2010 21:10, - wrote: Thank you for your answer, but as I wrote I don't want the sound of simple clipping like clip~, tanh~ or overdrive~.

Re: [PD] The economics of Open source
Pierre, These are very interesting and specific questions you have asked. I'm pretty sure there will be widely varied responses. How to pay for the development of free software is a major gaping hole between two viable logics, one that says you need to horde your own labor for personal gain (and so as not to be exploited), and another that says you grow more wealth collectively if you share with others. There is a ton of literature on the theory, but I find little on the practice. Who is doing what? I just now discovered the following recent articles from the free cultural forum and thought I'd pass it along: http://fcforum.net/sustainable-models-for-creativity In it they outline in not too many words various economic models for sustainable cultural (software included) development. best -august. On Tue, 8 Mar 2011, Pierre Massat wrote: I was trying to get Ardour to work last night and i came accross the forum on their website. I must say i was quite shocked to see how many posts were about money. I was equally surprized to see that the latest full version of Ardour isn't free (although you can name your price). Name your price is actually a characteristic of the download site, not the software. From what I read, Ardour remains FLOSS nonetheless. 1) What are the economics of open source software, and how sustainable is the model? FLOSS is not an economic model, it's a set of licenses (and of potential future licenses with the same basic characteristics). You use the license as a tool to come up with an economic model of your choice, but there are many possibilities, both with a pure FLOSS license (which is the case of Ardour), and with a hybrid approach (involving proprietary licenses in some way). How does it work for Pd? There is no such system for the Pd community. Each developer has his/her own economic model, which usually means something noneconomic like donating plenty of time for little return. 2) I get the feeling that open source developpers used to think that the idea of free (free beer...) software was cool, but 10 to 15 years down the line (that is, now) they're beginning to realize that they can't keep on doing this forever. Am I wrong here? It possibly happens to *lots* of people, but it doesn't make the FLOSS movement getting any smaller.

[PD] Polyphony and granular synthesis, etc.
Hi everyone, I'm revisiting granular patches as I work on some examples for libpd. Any kind of granular synthesis is, of course, heavily dependent on polyphony. That raises the question of how to instantiate multiple copies of the same abstraction. The issue is, many non-external methods of doing this right now depend on poly, which in turn assumes MIDI parameters. I would prefer something that uses arbitrary parameter lists. We actually could now do this two ways: 1. We can instantiate multiple patches when opening them in libpd, maintaining independent references to each patch, as Peter Brinkmann recently described on his blog - http://bit.ly/egBGV2 2. Perhaps there's a way to do this using an abstraction? nqpoly, etc., I believe did this, but it seems it's not supported - and may not be the best approach?

If I use an [#out window] object, which I believe is an x11 window, there's no way (that I can find) to go full screen, so I'm stuck at with an 800x600 window on a 1366x768 screen. I did attempt to use a [#scale_to (768 1366)] object to emulate being full screen but the scaling causes a massive drop in framerate. Can anyone suggest how to go fullscreen on only one screen, how to go fullscreen using an x11 window or some other way to do this? I'm using Gridflow 9.13 with Pd-extended 0.42.5 on a Dell Studio 1555 using the ATI Radeon 4555 proprietary driver running Ubuntu 10.10.

[PD] fiddle: amplitude scale for individual pitches
Hi, What's the scale of the amplitude value that comes packed together with each individual pitch? (i.e., the second value of the output of the third outlet in the help patch)? If you open the help patch as is and don't touch anything, the example signal (phasor) is being detected ah having an overall amplitude of about 90 dB, while the unpacked amplitude of the (only) individual pitch is about 116. How should I interpret this? thanks m. ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
Re: [PD] listing all available objects
Hi all -- there's a line in m_class.c in the class_new() function, just before the end, that you can uncomment to get Pd to print out every class as it's loaded (but not abstractions). Unfortunately that still doesn't tell you about every class in extra, since they're only loaded on demand. And yes, the source lives inside the binary release, contrary to the usual custom, and is intended to make it very easy to recreate old versions on new platforms. cheers Miller On Thu, Mar 10, 2011 at 10:57:00AM -0500, Mathieu Bouchard wrote: On Thu, 10 Mar 2011, Bernardo Barros wrote: 2011/3/10 Mathieu Bouchard ma...@artengine.ca: where ?

Re: [PD] fiddle: amplitude scale for individual pitches
The pitch track's amplitude is computed as the theoretical loudness of the track, which is computing by adding up the loudnesses of all the components, then converting back to dB. Loudness is incorrectly estimated as the fourth root of amplitude (should have been the fourth root of power, equal to the square root of amplitude, if one is to beloeve in sones as a psychoacoustically correct measure. So the broghter the sound, the bigger the number (and the louder it should sound relative to its actual signal power). I haven't looked, but if you throw fiddle~ a sinusoid the two amplitude measures should be equal. By the way, I think sigmund~ works way better than fiddle~ on most classes of input signals :) Miller On Thu, Mar 10, 2011 at 06:52:54PM +0100, Matteo Sisti Sette wrote: Hi, What's the scale of the amplitude value that comes packed together with each individual pitch?

Re: [PD] Polyphony and granular synthesis, etc.
Peter, You are correct that [poly] imposes a MIDI-like structure in that it works with note/velocity pairs. I just wanted to point out that it does not clip those tuplets in a MIDI way; i.e., you can pass floats for both note and velocity to your polyphonic instrument. Your general point is still taken, that a more generalized, perhaps list-passing [poly] would be very useful. BTW, I've made a granular-based polyphonic synthesizer for Pd; it's here: http://www.pkstonemusic.com/polygrainsynth.html , along with it's older sibling a subtractive/fm hybrid polyphonic synthesizer: http://www.pkstonemusic.com/polywavesynth.html .

[PD] Generative Pure Data based internet radio
Hi all, Some of you might have already seen this on the PD forum or written up on Create Digital Music (cheers Peter) but it's been mentioned to me that there are some people on here that still might have missed it so I thought I'd point it out again. My big project over the last two months or so has been PatchWerk Radio, a generative internet radio station that streams 24/7 and is built in PD and Python. The website if you want to have a look is at http://radio.rumblesan.com The idea is that python starts up an instance of PD which will choose patches at random from a list. It loads a patch up, plays it for 10 minutes then crossfades over to another randomly chosen patch. There are currently 20 patches on there the vast majority of which are from other people now. Hopefully those that haven't already heard about this will find it interesting. If people want to get involved and write some patches for it then that would be ace but even just having some more people listening would be cool. all the source for the server is available, as are all the patches, at github http://github.com/notesandvolts for those that want it. cheers -- Guy John ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Re: [PD] To divide a number in random parts
Hi guys. As I said before I wanted two complements to the wonderful solution by Matt Barber, and I just did the first! Is a patch that outputs bangs at random delays between them. The user can set the minimum and maximum duration between bangs (all in ms) and a setp size. This last one is easier to explain by an example: If the user set the minimum duration as 100ms, maximum as 2000ms and step size as 10ms the delays between bangs can be 100, 110, 120, 130 and so on, but never 115 or 127 for instance. Also, the patch runs a stopwatch that can be programed to... stop at a given time Everything can be saved to a text file, witch will contain the time of the bang (given by the stopwatch) and the time difference between bangs. This will allow me to create note attacks with durations that sound very random and non-directional. I putted all the commands inside a graph on parent so it can be used as an abstraction. I plan to create a bigger patch with Matt's, this one and at least one more. Hope you enjoy and give me feedback.

Never mind; this was my fault - found the glitch. I'm not correctly passing through the argument for the array. It's a symbol reference, but make_poly's message dispatching structure expects floats. I'm fixing it now. Anyway, because rjlib does all this dispatching for you, it's definitely the most sophisticated way to go - and it's still wrapping around poly. The question now is how easy it is, and how efficient it is, versus using libpd to handle the same tasks on the side of your code. So, whipping up a granular example is a good way to go, as it pushes the envelope a bit on both fronts.

Yes it's possible to pass an huge number to poly object, and then polypoly, that would be the result of multiplexed values.

Looking into it / open to someone pointing out anything obvious. ;) Peter -- Patrice Colet #N canvas 1044 378 476 437 10; #X obj 274 109 t b f; #X obj 208 167 +; #X obj 208 192 t b f; #X obj 208 223 +; #X obj 131 86 * 16384; #X obj 208 87 * 128; #X floatatom 131 54 5 0 127 0 - - -; #X floatatom 208 54 5 0 127 0 - - -; #X floatatom 274 55 5 0 127 0 - - -; #X floatatom 208 252 10 0 0 0 - - -; #X obj 208 280 t a a a; #X obj 376 320 mod 128; #X floatatom 376 361 5 0 0 0 - - -; #X obj 226 339 / 128; #X obj 226 363 int; #X obj 135 340 int; #X obj 135 316 / 16384; #X floatatom 226 386 5 0 0 0 - - -; #X floatatom 135 363 5 0 0 0 - - -; #X obj 225 314 mod 16384; #X connect 0 0 1 0; #X connect 0 1 1 1; #X connect 1 0 2 0; #X connect 2 0 3 0; #X connect 2 1 3 1; #X connect 3 0 9 0; #X connect 4 0 3 0; #X connect 5 0 1 0; #X connect 6 0 4 0; #X connect 7 0 5 0; #X connect 8 0 0 0; #X connect 9 0 10 0; #X connect 10 0 16 0; #X connect 10 1 19 0; #X connect 10 2 11 0; #X connect 11 0 12 0; #X connect 13 0 14 0; #X connect 14 0 17 0; #X connect 15 0 18 0; #X connect 16 0 15 0; #X connect 19 0 13 0; ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Hi Joe et al, I live in the area and would like to participate and help out in any way I can. -JN On Wed, Mar 9, 2011 at 8:12 PM, Richie Cyngler glitch...@gmail.com wrote: Sounds awesome!

This new LA patching circle will be hosted by CrashSpace LA. == We will be providing regular updates about pd_LAunch on pd list and elsewhere -- many arrangements are still in-progress. But please spread the word to those you know who may be interested -- whether they live in LA and may become patching-circle regulars -- or if they live anywhere in the world and just want to be part of the pd_LAunch launch-fest. The main purpose of this preliminary/early announcement is to help you in making travel plans, etc. if you need to. We especially welcome members of other patching circles (from other cities, other countries) to join us in LA and share your experience and inspiration. At the moment, we have set up an an e-mail address: lau...@pd-la.info where you can express your interest, support, plans-to-attend and other helpful ideas. Because the physical facilities at CrashSpace are fairly small and other venues are still being negotiated, it's VERY IMPORTANT that you RSVP yes right away if you plan to join us April 25 - 30 in LA.(Kindly make your RSVP via the email address: lau...@pd-la.info) We request that you also use the launch e-mail address especially to express interest in topics for workshops and/or demonstrations that you would be interested in attending. (See suggestions below.) Or you can use the e-mail to ask particular questions, to request travel and lodging advice and assistance etc.) All pd_LAunch events will be free and open to everyone, as much as space and facilities permit. For some events that will be limited by space, we will be providing some signup lists -- details forthcoming. We would also request that when you RSVP yes you would consider making a contribution to secure some of the spaces and amenities we will need. A suggested contribution is $50 USD. We welcome your contribution to this effort, with money or ideas or other help, even if you cannot get to LA in person. We can all support the new patching-circle there. (Money contributions, of whatever amount, should be made to New Blankets Inc. which is a U.S. 501(c)(3) tax-exempt organization; so your contributions are tax deductible if/as those laws apply to you.) Some events and highlights already planned: - VIP guests: Miller Puckette, Hans-Christoph Steiner, Chris McCormick, Natacha Diehls ... more invitations are in the hopper as well. - Opening reception/build/video-slam at UCSD with Miller Puckette Monday April 25 (San Diego) - puredata gym-full Family Night at the Long Beach Boys and Girls Club Wednesday Apr 27 - panel discussion with Miller Puckette and puredata developers Saturday afternoon Apr 30 - concert/party/reception Music with Miller Puckette and Friends Saturday evening Apr 30 (Miller Puckette, Natacha Diehls, Chris McCormick and more ...) - workshops and demonstrations by Hans Steiner, Chris McCormick, Miller Puckette and others are being arranged ... These will be based on what the interest/registrations indicate and depending on what spaces/venues in LA can be arranged. (Some spaces larger than the CrashSpace location may be required.) - A goody bag and other items available for pd_LAunch sponsors/RSVP'rs/contributors to include a 20-lecture puredata video course by Miller Puckette, pd_LAunch souvenirs made on the CrashSpace Makerbots, live-USB sticks ready to boot-up and run Linux/pd on any computer etc etc. - Store-front music a transformation of the street-front of CrashSpace into an interactive puredata experience, following up on the CrashSpace smash-hit effort for VIMBY. (Get your patch out on the street ...) Mark your calendars. Plan to join us in LA. All your efforts to help start a successful patching circle in LA are welcome. Let us know if we can help with travel, lodging or other arrangements if you are coming to LA from afar. Workshops/demos being planned (Please
