Live Coding is the creation of software while it is being executed; the software in turn generating music or video. Thanks to dynamic programming languages, the live coder is able to modify and extend their program without restarts, their music and/or visual growing with the code that describes it. This way of working allows instant results for every sourcecode edit. Programming becomes a fast, creative process - expressive enough that a whole audio/visual performance may be created as software. Live Coding began during the 1980s, primarily with FORTH and Lisp. In recent years new live coding environments and languages such as Chuck, Fluxus, Impromptu and SuperCollider 3 have appeared, with enthusiastic communities growing around them. Live Coding performances have also used Smalltalk, PureData, Scheme, Perl, Haskell, Ruby, Python... In early 2004 the Temporary Organisation for the Promotion of Live Algorithm Programming (TOPLAP) was formed to support open dialog between all live coders. Since its early beginnings in a smoky bar in Hamburg, TOPLAP has reached 178 members worldwide, gaining coverage in mass media and collaboratively organising several international meetings. In 2005 Access Space initiated the L.O.S.S. project (http://loss.access-space.org) to support free music creativity and distribution. It featured a series of commissions leading to a Creative Commons licensed audio CD and repository website produced entirely with open source tools. Continuing their series of LOSS commissions and events, Access Space have teamed up with TOPLAP and lurk to create a three day international festival, bringing live coding musicians and video artists together to explore and showcase new approaches in live performing and participatory arts. --- CALL FOR PARTICIPATION - Your performance and/or presentation proposal is called for. For the latest version of this call, please refer to http://livecode.access-space.org/ Commissions are available to help realise ambitious projects and performances. Presenters and performers will gain free entry throughout the festival, and those without institutional support may apply for a small bursary. --- IMPORTANT DATES --- * 14th March - Call for participation * 14th April - Deadline for proposals * 1st May - Notification of acceptance * 16th June - Copy deadline for proceedings (to be confirmed) * 20th-22nd July - Conference - schedule TBA --- PRESENTATIONS --- Short (up to 20 minute) presentations during a day long symposium. The remit is broad, but possible subjects may include * A demo of a novel live coding language/environment * Historical context of live coding * Live coding without computers * Critique of live coding practice * Live patching * Reflections on live coding experiences * Adapting general purpose languages to live coding * Analysis of live coding performances * Live algorithms that live code * Life coding * Portable live coding devices * Reflective/self-modifying code * Live visualisation of sourcecode * Collaborative networked live coding * ... Proposals do not have to be long - however much or little you need to explain your ideas is fine. If you are unsure if you can make it, submit your idea anyway - we may be able to accommodate a small number of remotely streamed presentations for those unable to attend in person. There will also be time for a brief (around three hours) introductory workshop. Please indicate if you would like to be involved. --- PERFORMANCES --- There will be at least two evenings of performances, ranging from 10 to 40 minutes. Please outline what you would like to perform, including technical requirements. We plan to have at least three data projectors, many pairs of small speakers for participatory improvisations, enough headphone amps for 100 pairs of headphones, and a big stereo sound-system for 'traditional' performances.

Re: [PD] Help - filters band limited oscillators!
I use Visual C++ Express Edition because it's free...Cygwin won't work, MinGW does. I'm still not sure if MinGW and MS compiled binaries are compatible (as in does a VCC dll work with a MinGW pd? VCC needs a pd.lib at link time but AFAIK MinGW can use pd.exe at runtime). I usually compile externals against Miller's latest version of pd from his site. For Visual C++ I make an empty project to build a dll, for the compiler include the path to pd/src and define MSW. For the linker include the path to pd/bin and add pd.lib as a dependency. In the linker command line add /export:sqosc~_setup. Then take the dll and put it in pd/extra. The help file goes in pd/doc/5.reference. That seems to be all that's necessary.

dude - you are a ninja. uhm, i mean, a jedi. seriously - i want to emulate you a bit when i grow up ;P that said, what resources would you recommend that illustrate calculus as used for signal processing, but from a more functional point of view as opposed to a theoretical one. i know there are dsp chip programming guides for engineering, but there seems to be only how and not the why in most cases there. too theoretical of descriptions makes it difficult for me to visualize the action or imagine the sonic implications of the theory being discussed. personally, i find that the application of theories make much more sense than the abstract theories themselves. maybe it's brain damage, or perhaps plain 'ol ignorance. but anyway, here's a simple example: someone tells me an empirical definition of the nyquist theory, it's hard to get my head around. but if someone says hey, you can't sample a frequency that is = 1/2 of the sample rate, because the wavelength is too short in duration to fit sample boundaries, and it causes distortions that are related to the frequency being sampled. that totally makes sense. i can picture that from a functional point of view, and then have a much easier time with the math an theory of it. are there any resources, books, etc out that approach the subject of dsp in a style like this? thanks and high regards, star On Thu, 2007-03-15 at 15:24 +, padawan12 wrote: [pow~] is from cyclone, I think in the case I used it (pow 2) you can replace it with an equivilent [expr~] expression or [*~].

The parasite synth is the wrong patch, and I thought I was talking about different oscillators, it should have been something more like the ones here. The oscillator is a dual-slope one in hoover-triangles.pd, much easier to pull out than the last mess. Another take is the hoover-pwm.pd, which is a juno voice basically, it's much brighter and fizzy down low. It just depends what you want more in the low registers, up high theres not so much difference. One is pulse width mod of a square, the other is slope mod of a triangle, both have a bit of frequency lfo on too at about 5 Hz. A fat Juno hoover noise uses the fast chorus so there's one on both versions. Each has the same sequence so you can compare the sounds. All the hoover flavours have a different character, like a highpass resonant filter makes an interesting addition. But what they share in common is a busy sound made by having 3 or 4 detuned components. Juno is a pwm + saw + square mix, with the square an octave down.

Hmm... it's an aesthetic idea not to clip graphics to rectangular bounds (so graphs can go out of their 'boxes') but it's another problem what to do when someone drags an object to a place with negative cordinates. I think it should stay where you put it and the GUI should just adjust scroll bars. TK's canvas object does something different (and very irritating).

I suppose by self-referential you mean, that the help-file for blosc~ has the same name as the blosc~-external. That is generally no problem and many older externals had their help files named like the object, because the help file is located in a different directory than the external. If you have installed the blosc~.pd help file in your Pd path, then of course you may have problems. (This might be an issue in pd-extended, I don't know, I don't use it normally.) The fix is to move blosc~.pd to 5.reference or rename it to blosc~-help.pd or write a bug report for pd-extended.

Re: [PD] oldschool rave synths
Funny, I tend to recommend two books to people: the Dodge/Jerse one for those who aren't mathematical (like myself), and the Roads one (the CMT) for those who are. Keeping in mind that whole chapters of the revised Dodge/Jerse--basically all the chapters on anything which are contemporary like granular synthesis--have been lifted almost verbatim from Curtis Roads' works, the Dodge/Jerse book is an excellent introduction. I still find that the CMT is like a bible, and when I'm scratching my head I can browse through it to find the right starting point. But it would be much more incomprehensible without the headstart I got from the Dodge/Jerse book. best, d.

So if you think PD is good for synthesis, let me know about it!!! ***Note: I personally don't use PD with Gem for VJing, and to make weird generative MIDI sequences, mostly... I never really considered synthesis a strong point for PD, for reasons that should now be obvious. i disagree with you in this point. i admit, that you'd need to make some effort and bring some knowledge about the topic, but that doesn't prove that pd isn't good in synthesis. however, subtractive synthesis is one of many synthesing methods you can do in pd. if it would be impossible to do subtractive synthesis in pd, it would still be wrong to consider pd as unsuitable for synthesis generally. anyhow, like often in a technical world, faults happen because human beeings are not perfect. i am sorry, that after all even my patch did not work on your computer. actually it is a very easy fix. for some reason my pd (0.40.2) didn't complain about my mistake. i changed the table-size to 515 now. it switches around 360Hz from raw_square to bandlimited square, that is why you didn't hear anything above that frequency. i really hope, it works now. cheers roman ~David On 3/14/07, Roman Haefeli [EMAIL PROTECTED] wrote: hello again i improved guenter's bandlimited square a bit. i noticed that it is hardcoded to 48kHz and accidently i was running pd at 48kHz, that's why it sounded quite good here. however, how far i can see it, the part, that selects the appropriate table, is not working as it should. i couldn't completely follow, how it works, but it seems to switch only correct from tab1 to tab2. for other tabs it switches at too high frequencies, which might introduce a bit aliasing. in my version the tables are generated on loadbang, which makes the file much smaller and easier to adapt for other waveforms. the tabselector is now dependent on the sampling rate, so it should sound well at different rates now. in order to provide the full spectrum even in low frequencies, i added a raw square generator. below a certain frequency, the oscillator switches to the raw square version, so that it should sound good at arbitrary low frequencies. the number of tables generated on loadbang can be changed. a bigger value lowers the frequency, at which the oscillator switches to the raw version and vice versa. i hope you'll have fun with it. roman On Wed, 2007-03-14 at 04:46 -0600, David Powers wrote: I found those, but are they really band-limited?

Another take is the hoover-pwm.pd, which is a juno voice basically, it's much brighter and fizzy down low. It just depends what you want more in the low registers, up high theres not so much difference. One is pulse width mod of a square, the other is slope mod of a triangle, both have a bit of frequency lfo on too at about 5 Hz. A fat Juno hoover noise uses the fast chorus so there's one on both versions. Each has the same sequence so you can compare the sounds. All the hoover flavours have a different character, like a highpass resonant filter makes an interesting addition. But what they share in common is a busy sound made by having 3 or 4 detuned components. Juno is a pwm + saw + square mix, with the square an octave down.

Sometimes there's table not found errors in PD though). yeah, above 16kHz. and also in my patch i noticed a bit of aliasing in these high area. maybe it would be better to switch to an [osc~], cause the waveform in the according table is a sine anyway. my patch has still one little problem with cpu-optimaziation. i think the best would be to split the whole frequency range in three areas: in the low area a raw square, in the middle area the bandlimited version and it the are, where no harmonics could be played anyway, it could switch to an [osc~]. i'd like to put these three parts in separate subpatches, so that the unnecessary parts could be switched of. the problem is, when the parts are switched off, the are not in phase anymore, when they are switched on, so at least the [tabosc4~], [phasor~] and the [osc~] should always run, only for keeping the phase. could that be optimized in some way? is it possible to retrieve the phase of these objects? of course the [phasor~] could always run, but is a [phasor~] cheaper than an [osc~]? roman ___ Telefonate ohne weitere Kosten vom PC zum PC: http://messenger.yahoo.de ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

I heartily recommend Steven W Smiths Scientists and Engineers guide to DSP, before tackling Perry Cook, Eduardo Miranda and our own Miller Puckette. Calculus is only a small part of the picture, maybe you use the word too broadly because it's just a technique that helps understand certain equations. For calculus you needn't really go above A level, a little of that with a good grasp of algebra, trig and geometry are a solid enough basis. Linear algebra and matrices are some useful tricks to put in your bag, and you can get a long way by reading many of the tutorials for Octave. this site rocks! http://www.dspguide.com/ haven't seen this one - will check it out. http://www.amazon.co.uk/Real-Sound-Synthesis-Interactive-Applications/dp/1568811683 As Chuckk and some of the other mathematicians have said here, some esoteric pure math like operator theory subsumes the whole subject, because sound is about changes and transformations, but I wonder what other peoples top 10 'must have' concepts are. I suppose it depends on your goals, for example a lot of composers learn a disproportionate amount of stats and distributions. i have been playing around with those a bit from a very lay perspective - mostly randomized scales w/ occasional octave shifting (random w/ %, usually). i'm a fan of generative work, and hope to get better at it as time goes by and i better my skills. i know there are dsp chip programming guides for engineering, but there seems to be only how and not the why in most cases there. too theoretical of descriptions makes it difficult for me to visualize the action or imagine the sonic implications of the theory being discussed. personally, i find that the application of theories make much more sense than the abstract theories themselves. maybe it's brain damage, or perhaps plain 'ol ignorance. but anyway, here's a simple example: someone tells me an empirical definition of the nyquist theory, it's hard to get my head around. but if someone says hey, you can't sample a frequency that is = 1/2 of the sample rate, because the wavelength is too short in duration to fit sample boundaries, and it causes distortions that are related to the frequency being sampled. that totally makes sense. i can picture that from a functional point of view, and then have a much easier time with the math an theory of it. I strongly agree with you about teaching theory in context. It is hard to pick good examples and write using only words so that the knowledge sticks. Sometimes symbolic representation is the only way to be unambiguous. That is why Puredata is a powerful teaching and exploration tool, the diagram is the program. We are also lucky to have people like Derek and Frank who write from a position of least assumptions. I find a lot can be learned by just browsing the archives. truly - i've learned so much from pd, the help docs (brilliantly implemented in pd themselves), and all of the rocking folks that share their ideas w/ the list so often. the pd archive is a super bad ass resource - one of the days i'm going to throw together a script that culls patches from the archives and makes the containing mail the readme.txt for them. are there any resources, books, etc out that approach the subject of dsp in a style like this? One of Eduardo Mirandas more gentle books Computer Sound Design gives a pretty broad read, it also has some fun Windows and Mac software on the CD ROM. And you can't go wrong reading classics like Roads. that's like the 3rd recommendation for Rhoads - guess i'll be picking that one up :) Perhaps it's important to know that classic DSP is only a part of synthesis and analysis. It's the implementation layer. true - but i think the digital representation has a definite impact on technique. Another area of wisdom to explore is physics. I like to start sound design lectures by explaining that sound is a branch of dynamics, particularly fluid dynamics. Physics really helps design realistic sound effects, to know about propagation, interference, reflection, damping, stress, elasticity and all that. Then you can make ballpark models of what sound waves are doing in an object of given materials and dimensions. There's a big section in the book I'm writing about knowledge, imperative, declarative and procedural, and how to move from a description to a model to a method. Really this is Software Engineering, but that's what we are doing at the end of the day. software and systems arch is what i do for a living, and one of the big reasons why pd has such a draw to me. i'm much better at

If the file exists and is not of any type handled before the SGI handler and not of SGI type either, the SGI decoder does not close the file handle. This happened several times when loading a *lot* of TIFF images on Windows during a Pd/GEM workshop at Videographe, this afternoon.
