Patch cords not showing
by Francisco Medeiros 24 Apr '17

24 Apr '17

Hello, I have compiled pd 0.47-1 on Xubuntu 16.04.2 and the patch cords that don't show exept if they are in a straight vertical line. I found a message from Peter Venus saying the same thing happens on a RPI 3 with the OpenGL driver so it is maybe a problem with my crappy video card? (It is an onboard intel card). https://www.mail-archive.com/pd-list@lists.iem.at/msg07395.html Anyone knows how can I solve this? Thank You.

Re: [PD] best licence for pd-patches?
by Dan Wilcox 24 Apr '17

24 Apr '17

GPL patches *can* be used as they are not compiled into an application and can therefore be updated by the user, satisfying one aspect of the GPL. I handle this in PdParty by having the built in patches accessible by the user in the app’s Documents folder, so the user can modify them at will. If you’re using a GPL patch as an abstraction, it’s *similar* to using a dynamic GPL library as far as I can tell. But I’m no lawyer... > On Apr 23, 2017, at 7:09 PM, pd-list-request(a)lists.iem.at wrote: > > From: Matt Davey <hard.off(a)gmail.com <mailto:hard.off@gmail.com>> > Subject: Re: [PD] best licence for pd-patches? > Date: April 23, 2017 at 6:46:00 AM MDT > To: martin brinkmann <mnb(a)martin-brinkmann.de <mailto:mnb@martin-brinkmann.de>> > Cc: "pd-list(a)lists.iem.at <mailto:pd-list@lists.iem.at>" <pd-list(a)lists.iem.at <mailto:pd-list@lists.iem.at>> > > > i heard, and then read, that GPL patches CAN be run in closed source systems running libpd, etc. > > it's just GPL externals that you can't use without sharing the code. > > There seems to be a difference in licensing laws between patches and externals, because externals need to be compiled into the binary, but patches are more like "media" which runs on top of that. > > I wish i could find the posts i read about that again....it did make it quite clear why there is that distinction. -------- Dan Wilcox @danomatika <http://twitter.com/danomatika> danomatika.com <http://danomatika.com/> robotcowboy.com <http://robotcowboy.com/>

best licence for pd-patches?
by martin brinkmann 23 Apr '17

23 Apr '17

i have searched the archive, and something similar has been asked before, but i did not find a solution... (and probably 'the best licence' is not the same for everyone) i want to: -encourage (re)using and building upon my patches and sharing the results. -discourage plagiarism -not lock anyone (especially myself ;)) out from using my patches in a commercial and closed 'environment' (like a game on steam or an android/ios-app) the cc-by-sa which i use all the time for music and pictures seems to be appropriate, but i understand that it is not intended for code. gpl? would be great not to have to think about when including other work released under gpl. but can i make exceptions when it becomes necessary (app-store...)? lgpl? i am quite stuck. but i think i should (finally) put a proper licence on my released patches...

maxlib/arraycopy
by Ed Kelly 22 Apr '17

22 Apr '17

I don't quite know what has happened to arraycopy from maxlib. It seems to expect, from the code, that the destination array is smaller or the same size as the source array. That's ridiculous. My source array is 90 seconds long and the destination arrays are small - the duration between two bonk~ events in an audio stream. My rechunk~ patch, which I extensively rely on for live sampling, has been broken for a while. I fixed it. Enclosed.

Re: [PD] nqpoly~ and dynamic object generation, loadbang issue?
by Samuel Burt 22 Apr '17

22 Apr '17

IOhZ, Thanks for clearing up the naming. Can I fix it on the wiki or would I need to re-upload. I looked everywhere but couldn't find a version number on the iem site where I downloaded the plug-in. It sure would be nice for that to be more visible. Was I right to get it from iem? I found what looked like an older version on git, but again, the version numbers were hiding from my eyes. Is it listed somewhere in the source code?

Re: [PD] symbol to float
by Jack 22 Apr '17

22 Apr '17

Yes it is a bug in my abs, the problem seems to come from the [i ] object in [pd symbol2int] which return float -2.14748e+09 if you send float 6.89756e+14. I have replaced it with [f ] and the result of the symbol "8.689756393432365" is now 8.68976 which now looks correct. Patchs are attached. ++ Jack Le 21/04/2017 à 18:23, hans w. koch a écrit : > hi jack, > > i tried with "array-symbol2float“, however feeding it „8.689756393432365“ (a messagebox with this number as a symbol) > would only produce output, when i put > list prepend symbol > list trim > between the message box and array-symbol2float. > but then this output was 7.99998, which seems like the first digit of my number converted to float. > > strange… > > but otherwise thanks for the pointer to these abstraction. will have to investigate. > > best hans >> Am 21.04.2017 um 16:12 schrieb Jack <jack(a)rybn.org>: >> >> This link could help...

Re: [PD] How to scratch large sound file ?
by Dan Wilcox 22 Apr '17

In case you haven’t tried, you can increase the max table resize value when loading via sound filer. See the sound filer help. By increasing the size, I’ve loaded pretty large files, although maybe not in the terms of hours. > On Apr 21, 2017, at 11:08 AM, pd-list-request(a)lists.iem.at wrote: > > It's supposed to be possible with tabread4~, by using the onset inlet.

symbol to float
by hans w. koch 21 Apr '17

21 Apr '17

hello, pd-vanilla question: trying to harness geodata from an xml file, i need to parse lines like this: <gx:coord>8.689756393432365 49.4138 109.18</gx:coord> with a combination of "list split“ and „list fromsymbol“ i end up with three message boxes, „8.689756393432365“, „49.4138“ and „109.18“. problem is, that the message box containing „8.689756393432365“ is a symbol and i can´t seem to find a way to reconvert it to a float, other then sending it thru a netsend/netreceive pair. (as per this tip from 2007: https://lists.puredata.info/pipermail/pd-list/2007-02/047499.html). its working fine, but i was wondering, if this really is the only vanilla solution? i might well be staring at the obvious and not seeing it... thanks in advance for any other pointers! best hans www.hans-w-koch.net
