sensing whether a window is active
by Liam Goodacre 13 Feb '18

13 Feb '18

Hi all Is there a way to sense whether a parent-level window is active? By "active" I mean that the window is in focus with the title bar highlighted. [cyclone/active] is able to sense whether the current window is active, but I specifically need to know if the parent (grandparent, etc) window is active. Solutions involving externals are welcome.

pix_film + particles question
by Nicola Pandini 13 Feb '18

13 Feb '18

Hi list, I have a patch with a cube-shaped particle system, with a movie applied on every face of every particle. I have experienced some strange behaviors in the implementation process, so I'm asking the list which is the correct way to do it. I'm using this chain order: [gemhead] | [part_head] | [part_velocity] | [part_gravity] | [part_source] | [part_sink] | [pix_film] | [pix_texture] | [part_render] | [colorRGB] | [alpha] | [cube] I previously put the [part_render] between [part_sink] and [pix_film], but the result was that the video was rendered with a speed 10x faster. Am I missing something else? Is there anything else I'm doing wrong? Are there other things to do in order to optimize it? Â Â Â Thank you :-) -- Nicola Pandini http://nicolapandini.damai.it

Save Pd console as pdwindow.txt
by Peter P. 13 Feb '18

13 Feb '18

Hi, it maybe that this is a new feature or not, but I only discovered today that it is possible to save the Pd console as textfile by selecting "Save as..." from its File menu. Since I was initially trying to save my patch as .pd file, it could be useful to distinguish the "Save as ..." for the Pd window as "Save Pd window as ..." perhaps. P

Hi, has anyone successfully instantiated the rtcmix object into Pd recently, or otherwise. I'm having trouble finding a version that works. Thanks Gene Sent from my iPhone

JIT expr/expr~/fexpr~ clones
by Alex 11 Feb '18

11 Feb '18

With an interest of playing with LLVM based just in time compiling I made a clone of the [expr] family of objects that parses, compiles and then executes the compiled code versions of the expressions you provide it. It could still use a little cleanup but I believe it has all of the features of the cloned objects now, plus a [print( message to print out the generated LLVM assembly. I'm curious if anyone has some CPU intensive expr~ or fexpr~ examples that I could try to benchmark these against? Also, does anyone have a good benchmarking solution for pd? Anyways, if you're interested in checking it out the source is here: https://github.com/x37v/jit-expr I'll submit a deken package once its been tested enough, I resolve a couple questions I have about potential memory leaks and finalize the licensing. -Alex

write tempo change with [midifile]?
by tim vets 11 Feb '18

11 Feb '18

Hello, I've been looking into writing out midi using mrpeach's [midifile]. Now I'm trying to write a tempo change message into the midi file. So far I figured out that the message format should be "FF 51 tt tt tt". (e.g. as described here http://www.deluge.co/?q=midi-tempo-bpm ) I'm not sure though, how to translate that into a message that [midifile] can accept to correctly write the tempo change into the file. I tried a few variations, like [255 81 500000( (for 120bpm) or by first changing the 500000 into three hexadecimal bytes, and then turn those into 3 floats [255 81 7 51 0( but all I get is extremely low tempi when I import that midifile into a DAW (I seem to get the most informative results with Rosegarden) Any ideas? thanks! Tim

Re: [PD] Can Pd pretend to be a USB keyboard?
by Dan Wilcox 09 Feb '18

09 Feb '18

There isn't a way to generate system-level key or mouse events from within Pd. You'd have to use the platform native interfaces and probably write some code or use a user testing/scripting library. I would go with the networking socket as that would work on both Windows and Linux. > On Feb 8, 2018, at 11:40 PM, pd-list-request(a)lists.iem.at wrote: > > Date: Thu, 8 Feb 2018 17:39:38 -0500 > From: William Huston <williamahuston(a)gmail.com <mailto:williamahuston@gmail.com>> > To: pd-list(a)lists.iem.at <mailto:pd-list@lists.iem.at> > Subject: [PD] Can Pd pretend to be a USB keyboard? > Message-ID: > <CAFPUnQnr5SE-zg1xiO5ACPK=tY=Sob9i_03SXSYWkBvZR2AhtQ(a)mail.gmail.com <mailto:CAFPUnQnr5SE-zg1xiO5ACPK=tY=Sob9i_03SXSYWkBvZR2AhtQ@mail.gmail.com>> > Content-Type: text/plain; charset="utf-8" > > I want to control OBS Studio with a MIDI device. > OBS Studio does not presently support MIDI directly. > > I want to communicate to my MIDI controller with Pd. > I want to translate MIDI note-on/off messages into keystrokes > and pass those on to OBS. > > Can I emulate "midikey2key" in Pd? > https://obsproject.com/forum/threads/control-obs-with-midi.32881/ <https://obsproject.com/forum/threads/control-obs-with-midi.32881/> > http://75r.de/midikey2key <http://75r.de/midikey2key> > > I guess I could also use obs-websocket > <https://obsproject.com/forum/resources/obs-websocket-remote-control-of-obs-… <https://obsproject.com/forum/resources/obs-websocket-remote-control-of-obs-…>> > > Thanks for your ideas :) > BH -------- Dan Wilcox @danomatika <http://twitter.com/danomatika> danomatika.com <http://danomatika.com/> robotcowboy.com <http://robotcowboy.com/>

Can Pd pretend to be a USB keyboard?
by William Huston 08 Feb '18

08 Feb '18

I want to control OBS Studio with a MIDI device. OBS Studio does not presently support MIDI directly. I want to communicate to my MIDI controller with Pd. I want to translate MIDI note-on/off messages into keystrokes and pass those on to OBS. Can I emulate "midikey2key" in Pd? https://obsproject.com/forum/threads/control-obs-with-midi.32881/ http://75r.de/midikey2key I guess I could also use obs-websocket <https://obsproject.com/forum/resources/obs-websocket-remote-control-of-obs-…> Thanks for your ideas :) BH -- William Huston: WilliamAHuston(a)gmail.com Binghamton NY *Public Service Mapping / Videography / Research* Blog <http://WilliamAHuston.blogspot.com> -- Facebook <http://facebook.com/billhuston> -- Twitter <http://twitter.com/WilliamAHuston>-- Youtube <https://www.youtube.com/channel/UCGijK1amWOLglT3YeTyEBNQ?sub_congfirmation=1> Document collections: VirtualPipelines <http://TinyURL.com/VirtualPipelines> -- BHDCSDimockArchive <http://bit.ly/BHDCSDimockArchive> Please support my work: TinyURL.com/DonateToBillHuston

re-construct a live image from data in Gem
by Benjamin ~ b01 08 Feb '18

08 Feb '18

Hello pd-list, For a project where we try to hack an open hardware echographic system, we grab live threw a network socket a flow of datas and store them in a table (the device produce 2 - 3 images per secondes, 125 lines per images, 1690 datas per line) It works well and we would like to produce a live image from the datas in Gem Does anyone has already done such a thing or could suggest an approach ? thanks Benjamin
