MIDI clkin and realtimein
by Luigi Rensinghoff 19 Aug '08

19 Aug '08

Hi Dear List and Listers...... for the first time i do more with MIDI i checked some posts in the archive, but they are quite old... The Problem: I would like to sync PD to an incoming MIDI-Clock, and the best would be to route it through PD to the MIDI-Equipment ... Is that possible on OS X ??? It seems [midiclkin] is working somehow but .. after measuring the time between incoming beats and converting it to bpm it is not quite exact... and i dont know how to send it to the output. I guess using somekind of external program that does the midi- patching is the choice... (Any Idea ?) Or are there any midi related objects, that are not in pd-extended, but compile on OS X, by now ?? midirealtimein...does still not work on OS X, right ?? Thanks Luigi

readsf~ question

Assuming both soundfiles are stereo, which of these constructions is best for mixing x number of files together? They seem to be produce the same result, at least to my ears...

Benchmarking a pd application
by Lau Llobet 19 Aug '08

i've just ended a pd application and i'm wondering how can i know it's cpu ram and HDD usage during it's execution time. I've been looking for testing programs in google for hours but all programs seem to test distributed aplications ( web services ... ) Thank you very much ! Lau.

Is anyone using csoundapi~?
by Mike McGonagle 19 Aug '08

19 Aug '08

Hello, I recently started to use the Csoundapi~ external, and was wondering if anyone has been using it, and if there are any troubles you have encountered. I also was wondering (after reading someone's posts) about the priorities under which these things run. I would imagine that with it being an external of PD that it runs in the same address space (maybe?) and that the priorities given to the code would be the same. Is there a better way to us CSound with PD? OSC? Can CSound be run as a server (alla Supercollider)? Also, is there a more recent version of the external? While I haven't experienced any troubles, I am wondering what version of Pure Data that the compiled version that comes with Csound 5.08 was compiled against.

preferences for abstractions
by marius schebella 18 Aug '08

hi, is there any chance to get something like the properties dialog for abstractions? (right click on abstraction to make changes to settings/default values). I guess not. will think of other solutions... marius.

Re: [PD] [PD-dev] recording the overall state of a patch

hi, pdmtl abstractions have a solution for state-saving, auto-gui creation, midi mapping, osc mapping. you need to install pdmtl abstractions, add it to your path and open 1.browser.pd http://www.workinprogress.ca/pd/pdmtl/browser.ogg (theora video (vlc)) http://wikifarm.koumbit.net/dataflow/PdMtlAbstractions pat forwind wrote: > Hello Everybody, > > Apologies if this is not the correct place to post this but could > someone point me towards ways to record/save the overall state of a > patch.

Yes... it should be documented better. .hc On Aug 17, 2008, at 2:18 PM, michael noble wrote: > thanks Hans-Christoph, > > Are the patches already applied?

extended compilation nightmares...
by michael noble 17 Aug '08

17 Aug '08

hello I know its not the most fashionable of distros, but I've been trying to get my head around setting up an installation of pd for openSuse 11. Unfortunately, not even vanilla is in the repos. This aside, I know I will need externals, and would prefer learning pd from the comforts that extended provides, so I'd like to build extended. I've had a go at following the various conflicting readmes, inevitably getting stuck at some point. The bigger problem is I don't really understand "why" I'm doing what I'm doing, and as such would really like to. So here's the first questions in no doubt a long series of questions that will demonstrate my ignorance, stupidity and inability to "search the archives" (which I have repeatedly) just so I can get this built and up and running: Why, after downloading a package called "source" ( http://downloads.sourceforge.net/pure-data/Pd-0.40.3-extended.tar.bz2), do I then need to download the source via a cvs download script (Pd-0.40.3-extended/scripts/checkout-developer-layout.sh)? Or do I not need to download the latter and only make the former (which seems to fail for want of Gem, which I don't really want anyway)? color me confused... -michael

Re: [PD] Firmata polling routines

The first step is to check for changing values at the digital inlets and immediately send them to Pd without delay. The second step is executed every 20 milliseconds. During that call, all data that was received from Pd is handled and the analog inputs are read and sent to Pd. I am not exactly sure how the second step is triggered, if it has a timer, interrupt or just runs as fast as possible. but it is definitely not triggered by Pd. marius. > > On 8/17/08, marius schebella <marius.schebella(a)gmail.com> wrote: >> Adityo Pratomo wrote: >>> Hi there everyone.

Firmata polling routines
by Adityo Pratomo 17 Aug '08

17 Aug '08

Hi there everyone. Can anybody explain to me how the polling routine on firmata works when handling multiple sensors input? I'm trying to found out myself, but i still couldn't get it. Or is it actually not a polling at all? Many thanks in advance :-)
