hallo, i just compiled pd from git git clone git://git.code.sf.net/p/pure-data/pure-data compiled it with jack: ./configure --enable-jack i deleted the .pdsettings file, when i change audioengine to jack, pd core dumps. here the strace output. select(9, [7], [], [], {0, 5000}) = 0 (Timeout) select(9, [7], [], [], {0, 0}) = 0 (Timeout) select(9, [7], [], [], {0, 0}) = 0 (Timeout) select(9, [7], [], [], {0, 0}) = 0 (Timeout) select(9, [7], [], [], {0, 0}) = 0 (Timeout) select(9, [7], [], [], {0, 0}) = 0 (Timeout) select(9, [7], [], [], {0, 5000}) = 1 (in [7], left {0, 2520}) recvfrom(7, "pd audio-setapi 5;\r\n", 3593, 0, NULL, NULL) = 20 --- SIGSEGV {si_signo=SIGSEGV, si_code=SEGV_MAPERR, si_addr=0} --- +++ killed by SIGSEGV (core dumped) +++ Segmentation fault (core dumped) pd core dumps also when i start it with: strace pd -nomidi -jack open("/dev/midi8", O_RDONLY|O_NONBLOCK) = -1 ENOENT (No such file or directory) open("/dev/midi8", O_WRONLY|O_NONBLOCK) = -1 ENOENT (No such file or directory) open("/dev/midi08", O_RDONLY|O_NONBLOCK) = -1 ENOENT (No such file or directory) open("/dev/midi08", O_WRONLY|O_NONBLOCK) = -1 ENOENT (No such file or directory) open("/dev/midi9", O_RDONLY|O_NONBLOCK) = -1 ENOENT (No such file or directory) open("/dev/midi9", O_WRONLY|O_NONBLOCK) = -1 ENOENT (No such file or directory) open("/dev/midi09", O_RDONLY|O_NONBLOCK) = -1 ENOENT (No such file or directory) open("/dev/midi09", O_WRONLY|O_NONBLOCK) = -1 ENOENT (No such file or directory) rt_sigaction(SIGALRM, {SIG_IGN, [], SA_RESTORER, 0x7fad3b792630}, NULL, 8) = 0 setitimer(ITIMER_REAL, {it_interval={0, 0}, it_value={0, 0}}, NULL) = 0 --- SIGSEGV {si_signo=SIGSEGV, si_code=SEGV_MAPERR, si_addr=0} --- +++ killed by SIGSEGV (core dumped) +++ Segmentation fault (core dumped) does anybody experiences the same problem? any idea how to solve this? best, alexander

[PD-announce] [OT] digital subtractive synthesis
by cyrille henry 13 Feb '17

13 Feb '17

hello, OK, the aim of this mail is to announce my new hardware synthesizer : http://nozoid.com/ocs-2 I already talked a bit about it on this list, but I did build a bunch of them and they are now for sale! But since we are on the pd list, let me talk about pd, synthesis and things I learned while building an high quality, analogue style, digital synthesizer. Here are 3 facts: 1) I often heard that pd sound badly 2) every user of the OCS-2 synth love its sound 3) I developed (and distribute) the equations use in this synth in pd before porting them to a hardware, so you can have the same sound in pd than in my synth. So, according to fact 3, why do we have fact 1? - Equations are not the only factor that "create" a sound. The way you control this equations is also very important. (see the "zipper" noise if you don't control the gain of an oscillator at audio rate). In pd, the data clock is by default SR/64, I.E less than 1KHz. The "line" object usually output a value at 50Hz. For my synth, data are computed at about 10HKz. This make a difference : LFO shapes are closer to the desired shape, and contain less aliasing artifact fast fader movement are more accurate ... Fortunately, this can be fixed in pd : [line] can output value at faster frequency, and data rate can be increase by reducing audio block size. Moreover, this can be done only where it's important, and you can keep default value where speed did not matter. - The precision of the control is also very important : in pd, fader precision are limited by screen resolution, and fader usually goes from 0 to 127. Shift clicking to increase resolution did not help if you want to move fast. from 20Hz to 20KHz, there is about 127 note, so don't expect micro-tonal resolution... A standard analogue system can easily have a S/N ration of 70dB, I.E a 12 bit resolution : more than 4K value from min to max It is also what the OCS fader provide. Unfortunately, it's not easy to have good/accurate control in pd. But that's not really a pd limitation... - The SR of the audio synthesis can also be important : the higher the SR, the more audio aliasing you can remove. And you don't need a 192K SR on your sound card, you can just oversample the part that need it in your patch, filter, and go back to a lower SR. But, better than trying to remove aliasing, it's better not to create it... - After few thread about band limited oscillator, I still see some people using the [phasor~] as an audio oscillator. No offenses, but let me be clear : [phasor~] is a very useful object, but it's not an audio oscillator. Use one of the BL oscillator abstraction if you are looking for a sawtooth signal. Using phasor~ as an audio oscillator only to hurt ears. So, if you know what you are doing and take few precaution, you should be able to make your patch to sound nice... Now that i tricked you to read this mail, please, go to http://nozoid.com and buy hundreds of synths to make me rich, or just dozen so that i can pay my bill (it cost a lot to build hardware). Well just sharing the website to your musician friend will help me. thanks and cheers, Cyrille _______________________________________________ Pd-announce mailing list Pd-announce(a)lists.iem.at https://lists.puredata.info/listinfo/pd-announce

"sorry: only 5 args typechecked; use A_GIMME"
by Chris Chronopoulos 13 Feb '17

13 Feb '17

Hi list, Some time ago I wrote an external for generating euclidean rhythms. It worked in pd-extended (0.43.4), which I was using at the time. Now I've moved over to vanilla 0.47.1, and when I try to instantiate it, I get the following error: class euclid: sorry: only 5 args typechecked; use A_GIMME objectmaker_euclid: only 5 arguments are typecheckable; use A_GIMME Bad arguments for message 'euclid' to object 'objectmaker' So I tried what it suggests, with A_GIMME, 0, and now I can instantiate it, but it doesn't work. As soon as I feed it a bang, Pd crashes with terminal output "Floating point exception". Code is attached. Any suggestions? What's this typechecking/A_GIMME business about anyway? _chris

Miller Puckette featured on the New Blankets Netcasts Sunday/Monday February 12/13
by Joe Deken 11 Feb '17

11 Feb '17

You can catch Miller Puckette in conversation about recent activities and performances by listening to *two* New Blankets netcasts -- for Sunday February 12 and Monday February 13. You'll find the audio for listening on each of those days at: http://newblankets.org (If you wish to make a contribution to "Pd worldwide welcome" activities -- including Pd Artists-in-Transit -- you may also pledge a donation on either of those days and a matching grant of $100 for each day will potentially double your contribution. ) Or just listen those days and enjoy some conversation with Miller, away from the keyboard ...

[PD-announce] Call for Papers: Algorithmic Electronic Dance Music
by Nikolai Collinsky via Pd-announce 11 Feb '17

11 Feb '17

[apologies for cross posting] CFP: Algorithmic Electronic Dance Music Special edition of Dancecult: Journal of Electronic Dance Music Culture Guest Editors: Shelly Knotts and Nick Collins http://dj.dancecult.net/ Algorithms are at the heart of the virtual studio software applications underwriting so much contemporary dance music, but are normally the prior preserve of music engineering teams rather than musicians. This special issue, however, engages with algorithms as musical material, and especially with music which is inherently founded on computer programming technique. A recent manifestation of this is the algorave, an explicit site of live algorithmic electronic dance music (EDM), produced through such means as on stage computer programming (algorave.com). Creators of EDM have vast amounts of software at their disposal, including specific musical programming languages; modern digital audio workstations now often include the capacity to utilise a programming language, such as Python and Max/MSP embedded within Ableton Live, or Logic’s MIDI Scripter. The history of algorithmic techniques within mainstream and experimental fringe dance music predates the coining of the term algorave (Collins and McLean 2014). Powerful computer music coding environments have been co-opted for use in club contexts, by such well known figures as Autechre (Max/MSP), BT (Csound, Composer’s Desktop Project), Cylob, Aphex Twin (SuperCollider), and Holly Herndon (Chuck), amongst many others. Some artists have written their own software from scratch, such as the generative gabba-techno artists slub, or commissioned others to supply it, as with Coldcut and the VJamm and Coldcutter programs. Research in this area extends from the introduction of new algorithmic techniques for the production of dance music, to the computational analysis of existing EDM, via critical appraisal of algorithms in the wild. Live realtime systems, as well as offline studio software, have been developed. An increasingly algorithmically literate culture will see increasingly algorithmically literate music, and the rise of music-oriented computer programming has great implications for future directions within EDM. (2014) Nick Collins and Alex McLean “Algorave: live performance of algorithmic electronic dance music”. Proceedings of NIME 2014, London // SUGGESTED THEMES // Potential themes for articles include (but are not limited to): - Analysis of the work of algorithmic EDM artists - Computational analysis procedures for EDM - Surveying algorithmic techniques in EDM production - Algorithmic composition projects based on EDM styles - Live coding and EDM - Web browser based dance music systems (e.g., via Flash, HTML5, Web Audio API et al.) - Music Information Retrieval (MIR) systems and EDM content creation - The programming of interactive systems for EDM creation - Music pedagogy through coding of EDM (e.g., Sonic Pi, EarSketch et al.) - Gender, ethnicity and social trends at the crossover of computer music and club culture - Collaborating with and through algorithms; EDM groups of musical programmers - Algorithmic audiovisuals for club performance - Performance and audience reception of Algorithmic EDM // SUBMISSIONS // Feature Articles: Feature Articles will be peer-reviewed and are 6000–9000 words in length (including endnotes, captions and bibliography). For policies, see: https://dj.dancecult.net/index.php/dancecult/about/editorialPolicies#sectio… “From the Floor” Articles: This special edition will also include articles in From the Floor format (750–2500 words), which are very suitable for an artist to critically evaluate their own practice, or an academic to discuss new experiments. This format will be of particular interest to scholars and practitioners who wish to share some of the insights of their work, but are unable to devote the time necessary for a feature-length article. See guidelines at the Section Policies link above. Articles must adhere to all style and formatting rules stipulated in the Dancecult Style Guide (DSG). Download it here: https://dj.dancecult.net/public/journals/24/dancecult_styleguide.pdf Multimedia Submissions: Dancecult encourages authors to complement their written work with audio and visual material. See the DSG for style and formatting requirements. // DATES AND DEADLINES // This special edition is proposed for publication in Dancecult on 1 November 2018. If interested, send a 250-word abstract (along with a one hundred word maximum author biography) to Shelly Knotts (knotts.shelly(a)gmail.com) by 23rd March 2017. If your abstract is accepted, the deadline for submission of a full article draft to the guest editors for their comments is 1 October 2017. Beyond that, the deadline for online submission to Dancecult (for blind peer-review) is 1 February 2018. Please send enquiries and expressions of interest to Shelly Knotts: knotts.shelly(a)gmail.com A PDF version of this call, with live links and editor biographies, is available from: http://composerprogrammer.com/algoraveCFP.pdf _______________________________________________ Pd-announce mailing list Pd-announce(a)lists.iem.at https://lists.puredata.info/listinfo/pd-announce

Hi there... I just got a bounce back from this address so I thought I would reply here instead: I am happy to host or coordinate hosting for artists that would like to present work in New Orleans. There are several venues in town that present experimental music on an almost weekly basis though they do book somewhat far in advance. If anyone is planning a tour of the Southeast and wants to make a New Orleans stop I will do my best to help them out. I also teach at Tulane University and could arrange for a lecture/workshop in one of my courses if that is desired. Cheers, Rick
