Pure Data (Pd) Patching Circle This Sunday 2014-09-21 3-8 PM At CRASH Space
by Theron Trowbridge 16 Sep '14

16 Sep '14

The next meeting of the pd-la patching circle will be this Sunday, September 21 at 3 pm at CRASH Space (10526 Venice Blvd, Culver City CA 90232). A patching circle is an informal gathering of anyone who is interested in patching languages (Pure Data, Max/MSP/Jitter, etc.). Beginners and experienced patchers are welcome. Open to everyone – work on personal or professional projects, school work, or just patch quietly to yourself, in a room full of other people patching patches and helping other people patch. Free and open to the public (donations to CRASH Space are welcome, of course). -Theron ^

leapmotion and hands
by Max 14 Sep '14

14 Sep '14

Currently leapmotion.pd does not let you know if the hand is a right or left one. This abstraction tries to work around this limitation, but does not fully eradicate it. It ultimately is a quirk, because the SDK should be able to know if it is a right or left hand because of the thumb position. However this information isn not available from within leapmotion.pd The abstraction has two modes which switch depending on how many hands are in the field of view: 1 one hand becomes present: will check if the hand appeared on the right or the left side from the zenith above the device. Assuming that it is the right hand if it appeared on the right side. You can then use the full space with that hand and it will keep its designation. Catch: make sure to initialize correctly and always approach the device with the right hand from the right and the left hand from the left. 2 two hands present: will check which of the two hands is rightmost and defines that as the right one. Catch: never cross hands.

Re: [PD] [PD-dev] Should message objects be able to pre-parse $0 into valid dollarzero?

Roman Hello It should be possible with some tcl magicks to turn $ found in message boxes to # or @. That also means that externals like gridflow wouldn't work anymore with this message system because it already uses # and @. Also this could drive to the introduction of a new variable into a patch for getting pd version that has been used to write it, and then unfortunately for devs, something more complicated using an historic library containing rules to retrieve the good code. I don't know the implications of introducing some wizard that rewrite code into patches for backward compatibility, but the idea looks seducing for me because it might break inertia that makes the GUI still looking like patching in the nineties. Sorry for the cynicism but it's truely a joke we sometimes share when it's about pd interface.

Should message objects be able to pre-parse $0 into valid dollarzero?
by Ivica Ico Bukvic 13 Sep '14

13 Sep '14

Miller et al, The current code suggests that this should happen (binbuf_eval calls the appropriate function), but since canvas_setcurrent is never called, it fails and returns 0. Yet, I wonder why message shouldn't be able to pre-parse $0 into a valid dollarzero (canvas instance), when there will never be a message one could send into it that could trump this argument (how would one specify an argument $0 anyhow)? I do understand that message is not meant to pre-parse values, but shouldn't this be an exception? That way one creating a message with an instance included does not have to go through the trouble of creating an [$0] object that needs to be packed with the rest of the list and then forwarded onward to a message object. Thoughts? If others are in favor of this idea, should this take place for all types of messages passed into message object (bang, list, anything, blob, etc.)? -- Ivica Ico Bukvic, D.M.A. Associate Professor Computer Music ICAT Senior Fellow DISIS, L2Ork Virginia Tech School of Performing Arts - 0141 Blacksburg, VA 24061 (540) 231-6139 ico(a)vt.edu www.performingarts.vt.edu disis.music.vt.edu l2ork.music.vt.edu

how to debug a PD patch
by plutek infinity 11 Sep '14

11 Sep '14

greetings! the question: is there a way to make pd tell me specifically what part of a patch is causing a crash, so i can identify the problem and fix it? the debug command-line option doesn't seem to give useful results for my current issue. background: i have a patch which is significantly complicated, including many subpatches, etc... it used to run just fine, but has recently started crashing when i click on some toggles in my interface. however, it's not always the same toggle that causes the crash, nor is it a reliable number or group of toggles, as far as i can tell. there was one message which was supposed to be received by a toggle, but which wasn't being received the last time i opened the patch. i fixed that error, and saved the patch. however, the crashing was happening both before and after that fix, so i'm afraid some other little things in the coding may have changed somehow. don't know how that could have happened, but anyways.... many thanks in advance... cheers! .pltk.

Re: [PD] store contents in table
by Ingo 11 Sep '14

11 Sep '14

That's the way I do it. This is also a good way for a preset management to save an entire patch with different settings. Takes a little organisation at first but works perfectly. You have to remember that writing to disk might interrupt the audio stream so you will have to write the tables manually to disk when no audio is being pruduced.

September 2014 05:34 An: Miller Puckette Cc: PD List Betreff: Re: [PD] store contents in table Yeah, I think the way to work around this is what I used: (stuff) | [tabwrite keymap] [table keymap] plus a couple messages: ) ; keymap write keymap.txt] & ) ; keymap read keymap.txt] & a [loadbang] to this last message should automatically reload the last saved values.

It's a mistake that the dialog box suggests that that would be possible. (Ordinary "arrays" do allow this. Also, a new "array define" object does - this was introduced in Pd 0.45 which as far as I know is only available as "vanilla". (Pd extended is based on a 2-year-old version of Pd.) cheers Miller On Wed, Sep 10, 2014 at 06:01:59PM -0700, Ronni Montoya wrote: > Hi, when i create a table using the object [table blabla] and then i > select the option in the table "save contents" and then i close the > patch and reopen it doesnt store the contents of the table.

store contents in table
by Ronni Montoya 11 Sep '14

11 Sep '14

Hi, when i create a table using the object [table blabla] and then i select the option in the table "save contents" and then i close the patch and reopen it doesnt store the contents of the table. This option just works when i create the table directly from the options. Is this a bug? Or is there a special way of storing the values of the table? Im using pd-extended 0.43.4 cheers R.

How to submit patches to to maxlib and other externals?
by Ivica Ico Bukvic 10 Sep '14

10 Sep '14

I have a fix that allows average object to accept arbitrary amount of arguments to average against, rather than being hardwired to 128. Also, does checks against negative values passed into the right inlet... So, where do I submit this? -- Ivica Ico Bukvic, D.M.A. Associate Professor Computer Music ICAT Senior Fellow DISIS, L2Ork Virginia Tech School of Performing Arts - 0141 Blacksburg, VA 24061 (540) 231-6139 ico(a)vt.edu www.performingarts.vt.edu disis.music.vt.edu l2ork.music.vt.edu

(Solved) pd~ subprocess not responsive
by Max 08 Sep '14

08 Sep '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 (I think the Gem error is unrelated, so I'm better opening another thread) with the pd~-help i am experiencing the problem, that I can't move the objects in edit mode, clicked message boxes will keep their highlighted border permanently. That's only in the child process. Audio and Messages however can be sent from and to the subprocess. - --- SOLUTION before sending the mail I found the problem, It may be useful as a future reference, so I am sending it anyways: I suspect that when trying to install the current Pd, I re-set the path settings. So in verbose mode I noticed that pd~ was found in /usr/local/lib/pd/extra I removed that path from the path settings and now pd~ is found somewhere else. It is the same (v0.3) but it works now. tried /usr/lib/puredata/tcl/../extra/pd~/pd~.pd_linux and succeeded -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iEUEARECAAYFAlQLGEcACgkQ3EB7kzgMM6KaFQCVGMrbYAuT2WxUJ5AWmOYlULvs mACfdZL/n8QFKM8rkpiSB5dHtrnX5rs= =umwA -----END PGP SIGNATURE-----
