delete node in tof [breakpoints]
by Hector Centeno 18 Dec '08

18 Dec '08

Hello, I was wondering if anyone knows how to delete a node (point) in the [breakpoints] object form the tof library. I checked the source code and it seems that this option is not implemented but maybe I missed something. Also I couldn't find any mention of this external in the pd-list archives, is there a more popular alternative? I'm basically using it to create breakpoint data that overwrites tables in a Csound orchestra running inside a [csoundapi~] object. Thanks, Hector

Dynamically Changing properties of a horizontal slider
by Thomas Mayer 18 Dec '08

18 Dec '08

Hello, I am trying to create a live sampler / looper abstraction. It will have two horizontal sliders with the start / stop point of the loop. As I will replace the recording during the performance, I need a way to change the values of the output range of the slider dynamically, e.g. to set the range of the slider from 0 to 44100 with [output-range 0 44100( | [s receive_name_of_hsl] Thanks in advance, Thomas -- "Prisons are needed only to provide the illusion that courts and police are effective.

nearest power of 2
by hard off 18 Dec '08

18 Dec '08

what's the easiest way for pd to find the nearest power of 2 for any float? so 10 would give a result of 8, 53 would give a result of 64, etc.. http://en.wikipedia.org/wiki/Power_of_two#Algorithm_to_convert_any_number_i…

Berlin Pure Data Meetings
by Georg Holzmann 18 Dec '08

18 Dec '08

Hallo Berliner! Since now many of the pd-graz people are living in Berlin (or at least Michi Pinter and me for now ;), it would be nice to meet some Berlin pd people (or similar). I heard that there was a pd stammtisch here, but I guess it is not active anymore ? So if anyone is interested - let me know ! (We also plan to make a workshop at some other time - if someone wants to contribute or attend she/he is of course very welcome!) OK, I am happy for any reply, LG Georg PS: As I am new here - has maybe someone tips which things are good to go to here in Berlin ? Maybe some locations/mailinglists/websites with nice events or communities ? - Thanks for any hints !

ehu abstractions (finally) released
by altern 18 Dec '08

18 Dec '08

hi so finally (i think) i made it with making the patches less messy avoiding ambiguous situations like the ones pointed out by few people in the list (thanks). So there it goes http://www.ixi-audio.net/content/download/ehu_abstractions.zip i also added some more docs, and even translated the docs to spanish (!). This is the description : EHU is a set of abstractions for PureData real-time graphical programming environment (http://www.puredata.org , http://en.wikipedia.org/wiki/Puredata). The main purpose of EHU is control/manipulate/analise/sequence video and audio in real-time. EHU encapsulates the complexity of programming with PureData to allow for rapid prototyping of interactive systems. EHU is developed for people with basic knowledge of PD but also for more advanced users to ease and speed up as much as possible the development. EHU also includes abstractions to control Arduino (http://www.arduino.cc) from PD (wraps pduino example by Gerda Strobl and Georg Holtzmann). Main areas covered by EHU abstractions are : video files, video cameras, pictures, audio utilities, general utilities. And again, this is thought to be used within PD extended. It uses few abstractions and externals included there. Check the readme file for more details on which ones are used and other details. enrike

messages to pd
by volker böhm 17 Dec '08

17 Dec '08

hi, could someone please point me to a list of all possible messages that the global "pd" object understands? (like "pd dsp 1", "pd quit" etc.). and a related question: is it possible to send messages to pd form "outside" of pd, but without talking to a patcher window? i have pd running on a remote computer and want to send messages to pd, e.g. like "quit". i know i could use pdsend, but if i understand correctly i would need a [netreceive] object in a running patcher, which then could pass the command to the global pd object through a message box or similar. but since the pd object is global, maybe there is a way of talking to it directly without the use of a patcher? thanks, volker.

traverse self?
by Chuckk Hubbard 17 Dec '08

17 Dec '08

I'm sorry, I think this was asked before, but I can't find it in the archives. Can a pointer be set to traverse the current patch? Like [traverse .( ? I'm trying to do it in an abstraction, so I don't know if it should have "pd-" before it, or if it's possible. -Chuckk -- http://www.badmuthahubbard.com

Delete scalars
by Lau Llobet 17 Dec '08

17 Dec '08

I'm building some grafics in my pd project. I add some objects with the [append] but i need to erase them, i have found no way to delete them except by using " ; pd patch-data clear " message or array resizing , non of them is usefull to me because i need to erase some of them with no order. I've read that *"Pointers are "safe": if you delete a scalar pointers to it are marked invalid."* so i think there'll be a way to delete scalars , in fact i can do it manually with a Ctrl-X. Is there any way to do it ? thank you very much !.
