[flext] Inheriting access to variables declared once in a library
by Christian Frisson 01 Aug '06

01 Aug '06

Hi, I'm currently using flext to develop a library of externals itself wrapping another C++ library. On the latter library, some setup classes have to be instanciated once only in a whole application. What's the way to benefit from inheritance in order to: - declare instances of those setup classes only in the base flext class of the library in order to create each only once; - share access with externals, being flext inherited classes of the base class? As I'm a poor C++ coder, the only ugly way I've yet found to circumvent this is declaring instances of those setup classes outside flext classes, statically. But for sure those variable won't get deleted and Pd sends a "read memory" error message when it's being closed... Any idea? Thanks, Christian

PD markov object
by c.m.bryan 01 Aug '06

01 Aug '06

Hello all, I'm needing some compilation help with the markov object I found here: http://icem-www.folkwang-hochschule.de/~finnendahl/pd.html (bottom of the page) I'm using it on linux, but I can't get it to compile on win32. Alternatively, if anyone knows of an alternative object, that would be just as useful. Thanks in advance, - Chris Bryan

qlist doesn't recognize "$0-whatever"
by David Powers 01 Aug '06

01 Aug '06

Hello everyone, I was thinking of building a sequencer with qlist, but I noticed a major defect: qlist doesn't seem to recognize the "$0-whatever" notation for dynamically specifying receive objects in subpatches. Would you consider this a design flaw, and is there any workaround? It would be nice to have multiple instances of my sequencer, rather than having to modify each instance with different send/receive objects inside. But maybe if I'm using numbers, I'd be better off building from scratch using arrays and my own textfile object anyway... Thanks in advance for your thoughts! ~David

pd and custom tcl/tk gui
by Andre Schmidt 31 Jul '06

31 Jul '06

hi, as pd uses tcl/tk as gui, wouldnt it be easy to allow users to add custom tcl/tk script/gui ? or how can i send values from a "tot" scriptlet to pd ? attached is a pd patch (tot-test1.pd) that opens a "tot" scriptlet (rectresize.tot) in canvas, where you got a rectangle that you can resize when click&drag on the rectangle edges... and i would like to send the sizes (or what ever) to pd... cheers -andre ps. some may know what i want to do: http://osku.de/svg/foo/cirseq001b.mpeg (was made with svg+ecmascript in firefox)

It consists of a Pd patch and an Arduino firmware, so it will work on any platform. USB or serial is fine. > 2) I saw a note in your patch in the Arduino site that the > interface can drain some CPU power: is Arduino the best interface > for PD and various sensors in your opinion? "Best" depends on a lot of things. Arduino is cheap, easy, and can do a lot. Its definitely a great way to start. Then when you have stuff working, you can think about which is the best. It might actually be the Arduino, or it might not. .hc > > Thanks for witing the external and doing all kinds of research! > Viva open-source! > -thewade ------------------------------------------------------------------------ The arc of history bends towards justice. - Dr. Martin Luther King, Jr.

Reminder: PD- Meeting in Vienna
by Breitschädel Hannes 31 Jul '06

31 Jul '06

Hi List! This is a reminder for the Meeting in Vienna: Tuesday, 1st of August, 19h00 at: Garten - Café - RÜDIGERHOF Hamburgerstr. 20 A-1050 Wien Tel.: 01/586 31 38 I've reserved a table in the garden for 5 .. 10 persons. I have not prepared an agenda or a plan, the meeting shall be more of the socializing, drinking beer type. nevertheless if anyone has interesting patches or a little presentation, bring it and show it. If we find out that we want more formal meetings e.g. with presentations of certain subjects we shall have them. looking forward to meeting you guys!

Human interface Devices for PD
by thewade 31 Jul '06

31 Jul '06

Hello again my favorite list! I am wondering if there are any human interface devices that provide a continuous amound of control, like Ms Pinky does for Max? I was hoping for a midi footswitch that can can operate like a pitch-bending wheel on a keyboard, and/or a rotating pad like a turntable that I can interface with PD somehow. Just using MIDI keyboards and audio input signals to control syntesis is kind of limiting. Has anyone here hooked up Scratch or Ms Pinky to PD? What would be even better would be if someone can point me to a kit I could build myself that I could hook up to a variable resistor, like a pan-pot, that could interface with PD in a continuous way (obviously there would be some sampling rate involved). Lastly, in the future is there a resource somewhere I should check first before asking questions like this here? I didn't see anything at puredata.org on this... Thanks everyone! -wade

PD and HID: Arduino
by thewade 31 Jul '06

31 Jul '06

Greetings Hans! I have learned from the net (and from Toby - Thanks Toby!) that you know a great deal about Human Interface Devices and interfacing thoes devices with software. I am hoping to be able to interface basic electronics like pan-pots and other vairable resistances with PD in a continuous way, and I have learnt a little about Arduino and saw that you have written an external for PD to inerface with this device. I have a couple of questions I hope you don't mind me asking of you... 1) Does your external work in Linux, and if so does it work with the serial or USB version of Arduino, or both serial and USB? 2) I saw a note in your patch in the Arduino site that the interface can drain some CPU power: is Arduino the best interface for PD and various sensors in your opinion? Thanks for witing the external and doing all kinds of research! Viva open-source! -thewade
