offline calculations with tilde objects?
by Roman Haefeli 19 Oct '16

19 Oct '16

Hey all When doing calculations on a large set of numbers, it's for obvious reasons much faster to do with tilde objects than doing it in message domain with some until loop. Doing calculations on an array with dsp objects has the disadvantage that they're tied to sampling rate and cannot be done instantaneously. So I'm asking myself if there is a way to eat my cake and have it, too, i. e. exploit the efficiency of tilde classes while retaining control of execution time. I know about the trick of up-sampling a subpatch so that you get _faster_ results, but it doesn't enable you to get the results in 0 logical time. Is "0 logical time" and "good efficiency" at the same time possible somehow? Roman

Can Pd rescan MIDI devices while running?
by William Huston 19 Oct '16

19 Oct '16

I've searched the list archives and do not find an answer to this. Would be nice to be able to plug in a new device and have Pd see it without exit/restart. Thanks. -- -- May you, and all beings be happy and free from suffering :) -- ancient Buddhist Prayer (Metta)

[PD-announce] Sounding Out The Space Conference
by Kerry Hagan 18 Oct '16

18 Oct '16

SOUNDING OUT THE SPACE: AN INTERNATIONAL CONFERENCE ON THE SPATIALITY OF SOUND Date: 2–4 November 2017 Location: Dublin School of Creative Arts, DIT Grangegorman Campus Organisers: DIT Conservatory of Music and Drama, Dublin School of Creative Arts, GradCAM Partners: Contemporary Music Centre, Irish Sound Science and Technology Association, Lewis Glucksman Gallery, Society for Musicology in Ireland, Solstice Gallery, Spatial Music Collective Conference website: soundingout2017.com <http://soundingout2017.com/> Keynote Speakers: Brandon LaBelle – artist, writer and theorist (Bergan Academy of Art and Design) Bill Fontana – American artist and composer Sound is an inherently spatial phenomenon. No matter what its point of origin, be it a musical instrument, a voice, an audio speaker, or another sound-producing entity, sound must navigate space before reaching our ears. On this journey it enters into a complex relational dynamic with the surrounding environment: it may be amplified, distorted, reverberated, dissipated and subject to a multitude of transformations which modify it in different ways. While this dynamic is an intrinsic part of any sonic event, certain artistic endeavours have sought to exploit this spatial aspect of sound as a distinct parameter in its own right. Though spatial experiments have a long history in western music stretching back centuries, the search for novel means of expression in the twentieth century led to an unprecedented investigation into the spatiality of sound as an integral component of the work. From Edgard Varèse’s Poème électronique to Karlheinz Stockhausen’s Helicopter String Quartet, such concerns have been at the centre of some of the canonic works of musical modernism. In the discipline of sound art, auditory dialogues with the surrounding space have been the defining feature of sound installations by Max Neuhaus, Bernhard Leitner, Maryanne Amacher and others, who have sought to locate sound in relation to architecture. While such work grew out of developments in the wider field of art installation, increasingly the practices of both sound and art installation have converged in the work of artists such as Janet Cardiff and Zimoun forming multi-sensory experiences. Expanding outwards, the multi-site sound installations of Bill Fontana have developed the notion of spatiality across geographical locations while recent innovations in communication and digital technologies have created virtual networks, redefining our conception of space and presenting new possibilities for music, sound art and visual art. Although substantial research on the spatiality of sound has been carried out within the disciplines of musicology, sound art, and visual art studies, much of this work has remained separate, enclosed within these specialised fields of research. This conference aims to address this imbalance, acknowledging the fluid exchange of ideas between these spheres in actual practice and fostering an interdisciplinary spirit amongst researchers and practitioners. The conference committee thus invites presentations from sound artists, visual artists, composers, academics, and post-graduate researchers which consider the spatiality of sound in all its diverse forms. While the conference remit is broad, the committee especially encourages contributions which address (but need not be limited by) the following three strands: • Sound and Visual Art ‒Contributions from Sound Artists/Visual Artists ‒Convergences between Sound and Visual Art ‒Historical Perspectives ‒Installation ‒Modes of Listening ‒Sound Architectures • Spatial Music ‒Analytical Accounts ‒Attempts at Definition/Theorisation ‒Composer Perspectives ‒History of Spatial Music ‒Listener Perception ‒Performance Challenges ‒The Role of Sound Technologies • Geographic and Virtual Spaces ‒Digital Networks and Communications Technologies ‒Live Streaming and Web-cast ‒Interactivity and Participation Proposals are invited in the following formats: •Individual Papers (20 mins duration plus 10 mins discussion) •Joint Papers (max 2 speakers, same format as above) •Themed Sessions (3 papers totalling 90 mins or 4 papers totalling 120 mins) •Panel and Roundtable Discussions (90 mins, max 6 speakers) Proposals for individual and joint papers must be in the form of an abstract not exceeding 250 words. Proposals for themed sessions, panels and roundtable discussions should not be more than 800 words and should indicate the number and title of each individual paper with its abstract. Abstracts may be submitted in either a Microsoft Word document or via a PDF attachment. All proposals should include the name, contact details, institutional affiliation (if any), technical requirements, as well as a short biographical note of not more than 100 words of each speaker. The conference language is English. Proposals should be submitted to soundingout2017(a)gmail.com <mailto:soundingout2017@gmail.com> All proposals will be subject to a double-blind review process by the conference’s scientific committee which is comprised of specialists from the disciplines of sound art, visual art and musicology. Applicants will receive notification as to whether their proposal has been accepted by early May 2017. The deadline for submissions is 31 March 2017 Conference Committee Dr Adrian Smith (Conference Chair) Dr Brian Fay (Acting Head of School, Dublin School of Creative Arts, DIT) Dr Mark Fitzgerald (Senior Lecturer, DIT Conservatory of Music and Drama) Dr Noel Fitzpatrick (Head of Research, College of Arts and Tourism, DIT) Dr Kerry Houston (Head of Academic Studies, DIT Conservatory of Music and Drama) Martin McCabe (Centre for Transcultural Research and Media Practice, DIT) Jonathan Nangle (Composer and Senior Lecturer, Royal Irish Academy of Music) Scientific Committee Dr Enda Bates (Composer and founding member of the Spatial Music Collective) Dr Brian Bridges (Ulster University) Jennie Guy (Independent Curator) Dr Kerry Hagan (Digital Media and Arts Research Centre, University of Limerick) Fiona Kearney (Director, Glucksman Gallery, Cork) Dr Victor Lazzarini (National University of Ireland, Maynooth) Dr Linda O’Keefe (University of Lancaster) Dr Karen Power (University College Cork) Belinda Quirke (Director, Solstice Arts Gallery, Navan) Prof Pedro Rebelo (Sonic Arts Research Centre, Queen's University Belfast) For further details please email: soundingout2017(a)gmail.com <mailto:soundingout2017@gmail.com> www.kerrylhagan.net www.spade.ul.ie www.dmarc.ie www.issta.ie _______________________________________________ Pd-announce mailing list Pd-announce(a)lists.iem.at https://lists.puredata.info/listinfo/pd-announce

could vanilla borrow iemlib's hi pass filter recipe?
by katja 18 Oct '16

18 Oct '16

In pd 0.47.1 [hip~] is still not perfect. Attenuation at cutoff is not constant over the frequency range: -6 dB with cutoff=SR/8, -3 dB with cutoff=SR/4, 0 DB with cutoff=SR/2. In contrast, iemlib's [hp1~] has -3 dB at cutoff consistently. Could vanilla pd implement iemlib's hipass filter recipe? I don't know if the license also covers the math. Documentation in https://git.iem.at/pd/iemlib/tree/master points to external literature for part of the math (bilinear transform). I've implemented the recipe with vanilla objects for comparison, see attached. Katja

[mtof~] !!!
by William Huston 18 Oct '16

18 Oct '16

I just discovered this! It looks like it shipped with extended? Also looks like it is in Max? This thing is awesome because it solves a problem I often have with LFO wave-shaping. I have an LFO like [osc~ 3] which has a range of (-1, 1). I want to be able to use this to represent a frequency scaler. So let's say that +1 is like +1VDC @ 1VDC/octave (like a modular synth). So +1 is like 12 semitones up (octave) and -1 is like 12 semitones down. However this seems really complicated to take a sine wave with a range -1,1 and scale that to 0.5,2 to represent a frequency scalar. (f * 0.5 = one octave down, f * 2 = one octave up). if V~ is your LFO voltage value (input) and you want to generate your voltage-scalar S~: Then it's something like *S~ = (2^(1/12)) ^ (V~ * 12)* This can be done with an [expr~] or with some math~, but it seems cumbersome to me. But if I can convert a (float) MIDI value to frequency value, *at signal rate*, then I can simply ADD my ordinary [osc~ 3] LFO (and also linear Bend-value) and i'm done. (I think of this signal-rate "voltage" representing frequency to be actually like * F~ = MIDIval + LFO~ + Bend)* This is so handy, I would like to ask that [mtof~] be added to Vanilla (if it's not already there) or maybe Alexandre can report if it is in his new Cyclone?

window close bug
by Liam Goodacre 17 Oct '16

17 Oct '16

Here’s another curious bug that I’ve just started experiencing (seems like I’m having one of those weeks!) Occasionally, the window cross icon on the top right seems to go rogue and start acting out another menu command. So every time I press it, it will zoom in on the canvas instead of closing the window, or create a comment, or (distressingly) save the file. These are the three that I’ve experienced so far. When it happens, it’s consistent, so that every open window has the same problem, and I have to force-quit PD (probably I have to force quit because the console cross icon has also been affected). I haven’t spotted a trigger for this behaviour yet, it seems to be random. Has anyone ever experienced this? I’m on 0.47.1, Windows 10.

Re: [PD] PD won't save preferences

Thanks Lucas, this is really helpful. By coincidence, I’ve been looking for the solution to the font problem too! From: Lucas Cordiviola Sent: 12 October 2016 12:03 To: Liam Goodacre;pd-list(a)lists.iem.at Subject: Re: PD won't save preferences Hi Liam, Yes, this used to happen to me but I have 3 Pds, 0.47.1, pdvst~ and Pd-extended. Here goes info if you don't want to reinstall if it happens again. One very good way to have control on this is via a .cmd file, in it you specify the same things that you can with “preferences/settings” and you use this .cmd to start Pd. Its just text in one line (make sure is one line only, never hit enter while you are editing) For example paste this on a new notepad and save as start-pd.cmd: ----- "C:\Users\Lucarda\Downloads\pd\bin\pd" -noprefs -font-face Consolas -font-weight normal -font-size 12 ----- change “C:\Users\Lucarda\Downloads\pd\bin\pd” to your pd\bin directory. Run it, you will get new font, IMO nicer. Of course you have to add all your -stdlib, and -path and audio config: Here's a list of all flags for 0.47.1: C:\Users\Lucarda\Downloads\pd\bin>pd -help usage: pd [-flags] [file]... audio configuration flags: -r <n> -- specify sample rate -audioindev ... -- audio in devices; e.g., "1,3" for first and third -audiooutdev ... -- audio out devices (same) -audiodev ... -- specify input and output together -audioaddindev -- add an audio input device by name -audioaddoutdev -- add an audio output device by name -audioadddev -- add an audio input and output device by name -inchannels ... -- audio input channels (by device, like "2" or "16,8") -outchannels ... -- number of audio out channels (same) -channels ... -- specify both input and output channels -audiobuf <n> -- specify size of audio buffer in msec -blocksize <n> -- specify audio I/O block size in sample frames -sleepgrain <n> -- specify number of milliseconds to sleep when idle -nodac -- suppress audio output -noadc -- suppress audio input -noaudio -- suppress audio input and output (-nosound is synonym) -callback -- use callbacks if possible -nocallback -- use polling-mode (true by default) -listdev -- list audio and MIDI devices -asio -- use ASIO audio driver (via Portaudio) -pa -- synonym for -asio -mmio -- use MMIO audio API (default for Windows) (default audio API for this platform: MMIO) MIDI configuration flags: -midiindev ... -- midi in device list; e.g., "1,3" for first and third -midioutdev ... -- midi out device list, same format -mididev ... -- specify -midioutdev and -midiindev together -midiaddindev -- add a MIDI input device by name -midiaddoutdev -- add a MIDI output device by name -midiadddev -- add a MIDI input and output device by name -nomidiin -- suppress MIDI input -nomidiout -- suppress MIDI output -nomidi -- suppress MIDI input and output other flags: -path <path> -- add to file search path -nostdpath -- don't search standard ("extra") directory -stdpath -- search standard directory (true by default) -helppath <path> -- add to help file search path -open <file> -- open file(s) on startup -lib <file> -- load object library(s) -font-size <n> -- specify default font size in points -font-face <name> -- specify default font -font-weight <name>-- specify default font weight (normal or bold) -verbose -- extra printout on startup and when searching for files -noverbose -- no extra printout -version -- don't run Pd; just print out which version it is -d <n> -- specify debug level -loadbang -- do not suppress all loadbangs (true by default) -noloadbang -- suppress all loadbangs -stderr -- send printout to standard error instead of GUI -nostderr -- send printout to GUI instead of standard error (true by defa ult) -gui -- start GUI (true by default) -nogui -- suppress starting the GUI -guiport <n> -- connect to pre-existing GUI over port <n> -guicmd "cmd..." -- start alternatve GUI program (e.g., remote via ssh) -send "msg..." -- send a message at startup, after patches are loaded -prefs -- load preferences on startup (true by default) -noprefs -- suppress loading preferences on startup -sleep -- sleep when idle, don't spin (true by default) -nosleep -- spin, don't sleep (may lower latency on multi-CPUs) -schedlib <file> -- plug in external scheduler -extraflags <s> -- string argument to send schedlib -batch -- run off-line as a batch process -nobatch -- run interactively (true by default) -autopatch -- enable auto-connecting new from selected objects (true by de fault) -noautopatch -- defeat auto-patching new from selected objects -compatibility <f> -- set back-compatibility to version <f> If you need to know the exact name of your ASIO sound card: prompt to your pd/bin dir and type: C:\Users\Lucarda\Downloads\pd\bin>pd -listdev -asio -stderr If not just use it to get numbers, here I specify asio in out in the same flag: -asio -blocksize 256 -audiodev "5 5" note the “ ” when there are spaces.
