fftease with pd 0.47.1 under OS X
by Jugen Frenz 28 Sep '16

28 Sep '16

Hello, I want to leave pd-extended behind me and use the newer releases of pd vanilla instead and then add the externals. When I define a path to the fftease folder in 0.47.1 as I used to do in pd-extended the library is not recognised. Also dragging the darwin objects into the ‘extra’ folder inside the application folder didn’t work for me. Please, what do I need to do? Any advice is largely appreciated… Best regards Jurgen

HID APIs and PlayStation Move LED support
by Mikael Bouillot 27 Sep '16

27 Sep '16

Hello list, I need to get access to a PlayStation Move Motion Controller [1] from Pure Data. All inputs (buttons & sensors) and outputs (LEDs & rumble) should be accessible. Basically, I need the equivalent of the [pd-wiimote] object, but for the psmove. I have spent the last few days exploring the various libraries, drivers and APIs that relate to my problem, but now I need some help to make sense of it all. First, I'm on Linux. So I connected the controller by bluetooth, and after loading the hid-sony kernel module, I got my input devices (/dev/input/jsX and /dev/input/eventX). I found out that LED support for the Move controller was added in kernel 4.2, so I upgraded my kernel. I then tried accessing it with [hid], and it worked fine but only for inputs. The doc says "For those interested in output support, checkout the alpha [hidio]", so I tried that next, but I couldn't seem to find the LED controls on my device. That's when I realized what's wrong: First, both [hid] and [hidio] use the Linux input API as backend ("evdev"), rather than the lower-level "hiddev" or "hidraw" APIs. Basically, that means that *all* communication from PD to the device *must* pass through the hid-sony driver. Second, the hid-sony driver doesn't seem to expose the LEDs through the evdev API. Instead, what it does is register the LEDs through the Linux LED subsystem (with led_classdev_register(), accessible through /sys/class/leds/*). That's why I wasn't seeing any LEDs on my device with [hidio]. Third, even if the hid-sony driver *did* expose the LEDs through the evdev API, this API only supports binary (on/off) LEDs, not variable brightness ones like on the Move controller. The net effect of this is that it's effectively impossible to control my LEDs using [hidio]. I did write a quick hack to control the LEDs through /dev/class/leds and it worked fine, but that's not a realistic option: I would like the whole device to be controlled through a single object. So here I am, wondering what to do next: a) I could use the existing [hidio] to get inputs and control force-feedback, but I would then need a second object to control the LEDs, b) I could write a dedicated object ("pd-psmove") that would bind to a low-level API (hidraw) and get me all that I need but would much less general, c) or I could write a general input interface ("pd-hidraw") that would provide lower-level access to the HID stack than [hid] or [hidraw]. I have read the hidio paper [2], but that doesn't seem to address my main problem of being restricted by the limitations of the chosen backend. I would very much appreciate any suggestion, especially from the hidio authors. Thanks in advance, Mikael [1] https://en.wikipedia.org/wiki/PlayStation_Move#Motion_controller [2] A Unified Toolkit for Accessing Human Interface Devices in Pure Data and Max/MSP (http://alumni.media.mit.edu/~dmerrill/publications/dmerrill_NIME07-HID.pdf)

[PD-announce] Call for Participation: ALMAT Workshop at Impuls Academy
by David Pirrò 26 Sep '16

26 Sep '16

Call For Participation: Workshop "ALMAT: Algorithms That Matter" Impuls, 10th International Ensemble and Composers Academy for Contemporary Music 2017 (http://www.impuls.cc) with David Pirrò, Hanns Holger Rutz and Agostino Di Scipio February 11th - 19th, 2017 IEM, Institute of Electronic Music and Acoustics, University of Arts, Graz Algorithms That Matter (ALMAT) focuses on the experimentation with algorithms and their embedding in live performances. Rather than conceiving algorithms as established building blocks ("live electronics") or the formalisation of a compositional idea ("algorithmic composition"), we look at them as performing entities whose consequences are irreducible to models. Algorithms "matter" in the sense that matter and meaning cannot be distinguished, they may be moulded and they may unfold material in an ecosystemic way: Materials become a new source for transformation. This workshop seeks to attract computer music practitioners, sound artists and composers by offering a platform for exchange and reflection about their personal approaches towards algorithmic experimentation. The participants are enabled to further develop their approaches, where special emphasis is given to the reciprocal coupling of their respective systems. The workshop starts with an internal presentation of the participants for the other participants and tutors, followed by an in-depth analysis and discussion of the different approaches. The rest of the workshop takes a semi-structured form, open to adaptation to the interests of the participants. Focus will be on the mutual engagement and the production of connecting points between systems, using both data and sound links. At the end, concert slots within the impuls festival are allocated for the participants to present either existing works or new works developed during the workshop. The workshop will be held at the CUBE performance space of the Institute for Electronic Music and Acoustics (IEM). The CUBE is equipped with a 24-channels periphonic loudspeaker setup for advanced sound spatialisation and an 18-cameras infra-red motion capture system allowing bodily motion to be used as input for sound synthesis and processing. The workshop Almat was developed by David Pirrò and Hanns Holger Rutz (both IEM Graz) and will be realised together with Agostino Di Scipio. http://www.impuls.cc/academy-2017/special-programs.html#c3426 ALMAT is part of the 10th international impuls Academy, taking place in Graz, Austria, from February 10th to 22nd, 2017. To register and find out more about impuls and the Academy please visit: http://www.impuls.cc/academy-2017.html How to apply: 1. You have to register and be accepted as participant of the impuls Academy 2017 first. 2. Please name your interest in participating in ALMAT already with your application or by sending an E-Mail to office(at)impuls(dot)cc (concern: ALMAT). 3. Please send a description of your personal work in relation to the workshop's theme stating your previous experiences and describing employed computational approaches, their aesthetic motivation and possible ideas for connecting to other system (up to 500 words) and a Curriculum Vitae (again 500 words maximum). Please send both part __to office(at)impuls(dot)cc until October 1st, 2016__ at the latest. 4. The selection of participants will be announced by beginning of November 2016. 5. If selected please make sure you bring along your own computer, software, controllers and audio interfaces. 6. Please be aware that the participation at ALMAT requires a daily presence and is to be considered as one of the very intense special programs. This implies that ALMAT participants will not be granted the same amount of individual lessons with other tutors as regular participants. _______________________________________________ Pd-announce mailing list Pd-announce(a)lists.iem.at https://lists.puredata.info/listinfo/pd-announce

HiDPI woes
by jason 25 Sep '16

25 Sep '16

Heya. I'm a long-time Pd user who just upgraded to a laptop with a high-resolution screen. Debian sid (unstable), Pd 0.47.1-1. I saw a discussion on the list from back in April, and I'm aware of the zoom feature and the ability to specify font size on the commandline. Even so, the main UI is absurdly microscopic and mostly unusable. Here is a screenshot of an example patch run with -font-size 64. http://imgur.com/a/q7yce Keep in mind that the screenshot is pixel-for-pixel, and that pixels are very small on this display. To see what it actually looks like on my laptop screen, hit Ctrl-minus (zoom out) about 5 times in your browser. For reals. I honestly don't use the menus that often, but the inlet/outlet handles are also very tiny and make patching difficult/frustrating. So what else can be done? Any clever work-arounds? I've fiddled with ~/.wishrc and ~/.tclkitrc files and they seem to have zero effect on the UI appearance. Thanks! -jason

[pd] gui fudi patuti
by Billy Stiltner 24 Sep '16

24 Sep '16

hey, lets say an enourmous patch has been constructed that exceeds the patchers current processor capacity attainable on one machine. even if the patch has wrongfully with good intentions anMVC sorta interface tied into the tcl tk simcomplexity, would a live capable solution to on one machine run pd with the ui and audio disabled while on another machine run pd with the gui disabled and audio enabled? if this did work and the audio did not glitch every time you move the mouse araound and instead the idea was implemented on one machine would this clarify that you just need to interrupt the machine at it's mouse setting vector and increas the mouse in the temporal direction? or does one only need to read the entire sourcecode of tcl tk to understand what is going on.com secondly how is mobmuplat different than say nexus ui for popular ddevices like android iNoids. thirdly on each of these ui platforms how are dynamic things like cloning the ui and spawning the coresponding monstrosity in pd? maybe this is all we want to be able to tinker with the design in real time at the most least footprint in the memory and cpu cycle . p.s. don buchla blast off memorial jam session

Can you try the “autotools_updates” branch from https://github.com/pure-data/pure-data/tree/autotools_updates <https://github.com/pure-data/pure-data/tree/autotools_updates>?
