Finding "$0" and dealing with it in messages
by Alexandre Porres 15 Nov '09

15 Nov '09

Hi folks, what's up? Hope you're all well. I find it somewhat annoying that $0 doesn't work on messages, is it really impossible? Now, the worst part is that if you need to go to the find menu and search for "$0-something" it does not find it!!! Is there any way around it? I even tried sending a message to pd properly but it insists on saying things like "1002-something" not found... Wouldn't it be nice if some core code changes were made so finding "$0" and dealing with it in messages would work? I wouldn't know how to do it anyway... Does this bother other people who knows how to? :) Thanks a lot See ya

how to nqpoly?
by João Pais 15 Nov '09

15 Nov '09

Hi, I need to do a polyphonic patch. Since there is no poly~ object, I was looking into nqpoly4. I know that several people work with it, but I myself couldn't understand it fully. The examples that come with it work, but don't explain that much (a pair of extra comments would be quite helpful). I also saw nqpoly5 mentioned in the pd-list, but doesn't come with pd-ext. Also, http://pix.test.at/'s site is currently down (creator of nqpoly4). So, I wanted to ask: - what is the most current version of nqpoly? - does anyone has a simple patch / some documentation that explains how it works? I'm not really interested in the internals, just to know how I integrate my patches with it. - is nqpoly4 the most recent stable version? (I could also try to spend a couple of days working with it and trying it out, but I really don't have the time for now) Thanks again, JoÃ£o Pais -- Friedenstr. 58 10249 Berlin (Deutschland) Tel +49 30 42020091 | Mob +49 162 6843570 Studio +49 30 69509190 jmmmpais(a)googlemail.com | skype: jmmmpjmmmp

Re: [PD] object that blocks stream of numbers unless new values
by Ingo Scherzinger 15 Nov '09

15 Nov '09

Hi enrike, >is there a spigot type of object that blocks numbers from a stream unless the value is different than the previous one that arrived? I've made such an abstraction some time ago. Hope it helps.

'apple' lib for controlling hardware and getting sensor data
by Hans-Christoph Steiner 15 Nov '09

15 Nov '09

Hey, I just finished of a quick library of functions for controlling some of the hardware features on Apple computers when running under Mac OS X. So far, I have been able to control the screen brightness; control the keyboard backlight brightness and fade time; get data from the "sudden motion sensor" or built-in accelerometer; and get data from the built-in light sensors. It's included in the nightly builds as the 'apple' library, check 5.reference -> apple in the Help Browser for help patches. Also, this should be pretty easy to do for other computers. For example, the Thinkpad features are pretty well documented under Windows and GNU/Linux: http://www.almaden.ibm.com/cs/people/marksmith/tpaps.html http://www-128.ibm.com/developerworks/linux/library/l-knockage.html http://www.almaden.ibm.com/cs/people/marksmith/sdl.html http://www.gnome.org/~fherrera/gtollina.c Or for Apple hardware, there is pbbuttonsd: http://pbbuttons.berlios.de/ .hc ------------------------------------------------------------------------ ---- ¡El pueblo unido jamás será vencido!

jack_transport~ little patch:rewind
by Lorenzo 14 Nov '09

14 Nov '09

I have added a rewind functionality to the jack_transport~ object by Jacob Lee to ease use with Ardour. I can't seem to find a contact to let the author know... It was a very simple cut and past and edit looking at the transport.h from jack source. Not sure if this is of any interest. Anyway maybe the author is on this list? Attached is the diff. Kind regards, Lorenzo.

Re: [PD] Finding "$0" and dealing with it in messages
by Matteo Sisti Sette 14 Nov '09

> The way I see is that $1...$n are related to the inheritance concept. > They > could be used inside [send~] & [receive~] objects to force some > sort of > locality, but you can't really guarantee locality by that, it is just > some way around that is not 100% safe There's no guarantee of "locality" whatsoever in using $0 either. If you create a [send $0-xxx] and the identifier of the containing (instance of an) abstraction happens to be 1032, and then in some other patch or abstraction you have a literal [receive 1032-xxx], the "locality" will be lost. Using $0 as a prefix to the name of "local" sends and receives preserves locality only provided that you never use "literal" numbers as a prefix in the name of sends or receives. So $0 is not so different from other creation arguments (i.e. $1...); the difference is that it is assigned automatically by the system and that it is done in such a way that no two instances of any abstraction will have the same value of $0. Using it for creating "local" names is just one way of using it, just as you can use explicit creation arguments for the same purpose (by taking the responsibility of ensuring uniqueness), although it is probably its main "intended" use. -- Matteo Sisti Sette matteosistisette(a)gmail.com http://www.matteosistisette.com

Space for pd under Windows
by Isidro Gonzalez 13 Nov '09

13 Nov '09

Hello: Does anyone compiled and/or used the pd implementation of the Space Unit Generator of F. R. Moore made by Yadegari? Here is the link: http://crca.ucsd.edu/~yadegari/space.html If someone knows where to find the compiled external and/or a Windows-adapted code, that will save me a lot of work. Best Isi
