What is the current, correct way to use Open Sound Control with PD?
by Paul Keyes 09 May '16

09 May '16

I need to use OSC. I had been using mrpeach in pd-extended, but I see that pd-extended is no longer recommended, and it won't compile for my system anyway (I'm using unbuntu 14.04 on an Udoo), so I have pd-0-46-7 installed. I downloaded pd-osc from my package repo, but there is no hint about where udpsend is supposed to come from. There is no pd-mrpeach from my repo either, so I'm currently trying to get the version from https://svn.code.sf.net/p/pure-data/svn/trunk/externals/mrpeach/net/ working without much success. It compiles but I still get "udpsend ..couldn't create". What is the correct way to get udpsend? Or is there another way to do OSC? Cheers, Paul

zexy objects not created

windows 10 zip version of Vanilla 0.47test downloaded externals with 'deken' put [declare -stdlib external] for all of them. works for all except for zexy. in declare-help it says: if you have zexy installed in the directory extra/zexy you can get it using [declare -stdpath extra/zexy]. thus i did. again the zexy objects in my patch couldn't be created. in the help browser everything shows up including zexy (2x) what's wrong with me/zexy ? rolf (BTW deken gives a choice out of 2 zexy's, what's the difference?

Dynamic search paths and [declare] behavior in Pd.0.47
by Jérôme Abel 09 May '16

09 May '16

Hi list, With the new [declare] behavior, I am a little confused (Pd.0.47). I've read that putting [declare] in abstractions was not the "right" way, but that what I've done. Shame. In La Malinette (malinette.info), it is very useful to have an abstraction named [include] which contains all relatives paths of all abstractions folders. The goal is to be user friendly and not ask people to add 6 paths in preferences ... And if I want to change a path, to add a common feature for all patches, I have just to change it once, all patches that have this abstraction are affected. And I want to add paths to my patchs I have just to remember the name of [include] to add this object and paths. These are benefits of having abstractions, like object-oriented programming. How can avoid to copy/paste 100 times a subpatch which contains [declare] and all paths, in all my files ? Or may be there is a way to add dynamically paths on all patches or current patches ? I can't see [import] in Deken, may be it could be the right way to add this kind of feature ? Is it downloable ? Thanks, Jerome

To: Roman Haefeli <reduzent(a)gmail.com> Ok Thanks. I'm trying oscformat etc., but after receiving the osc message and printing with [print parse-output] I get: "list state 3" where "state" is my osc address, so it seems like [list trim] isn't working.

[mod] vs [%]

Can we confirm that? And, if so, why? And how about fmod? Sames as %? By the way, the [%~] (or [modulo~] object - also present in cyclone - uses "fmod". And "fmod" in expr family also uses fmod... But anyway [%], [mod] and "%" in [expr] use the "%" operation in the C code... On my system, -10 [mod 3] and -10 [% 3] in Pd work differently. [mod] > outputs the positive remainder, which is 2, while % outputs the remainder > with the sign of the dividend, which is -1. > I also get that, and I'm on a mac intel... and this behaviour with the [%] object is what you get if you are using a code in C with "fmod"... (%~ and "fmod" in expr). And well, looking at the source code in x_arithmetic.c, both % and mod rely on the "%" operation in the C code, but [mod] turns the input negative values into positive input values "if (n2 < 0) n2 = -n2;" [%] and [expr $f1 % $f2] use "%" in the C code without turning negative input to positive input, so the results are the same. I'm getting the same behaviour as Matt, but if there's this deal with different results depending on architecture, then % in [expr] is subject to the same effect. But anyway, again, comparing to others in Pd and Max, it seems like the [mod] object is the odd one out, where it converts negative input to positive input on purpose. Lets say it has this behaviour intentionally, but also that we could keep [%] with this other intentional behaviour. If the way things are coded makes it undefined or dependent on CPU architecture, then it's a bug and we could force it to behave always in the way where -10 [% 3] gives "-1". cheers

[OT] choice of sound cards for 16 output channels
by Jack 08 May '16

Hello, With the following configuration : Ubuntu 16.04 Pd-0.47.0 I need to find a solution to send sounds on 16 different speakers. What is your advice regarding the purchase of USB sound cards under Linux with this configuration ? For you, which sound cards are more willing to do this job ? Ciao. ++ Jack

Uninstall pd on OSX
by Wilfred de Zoete 08 May '16

08 May '16

I'm having issues on 10.9.5 with installing a new version of pd (0.46-7) - I've been using a 2013 pd extended for years but that one froze on me. But now when throwing it away and installing a new pd I get plenty conflicts with different paths. Installing exernals gives errors too; some install, some give conflicts and others refuse. How can I clean the system totally? I've been deleting all pd's and the pure data files 'user \ library \ save application state' but still errors. By the way: the menu doesn't work too (copying, pasting et cetera from the menu).
