RE: [PD] Still trying to grasp the zen mind
by alberto.zin＠poste.it 19 Jun '06

19 Jun '06

Ciao Cesare, thanks again for sharing the piece: for me (newbie) it is a good example of how PureData can be used to drive an external synth. BTW: on Windows it worked fine at the first attempt (PD, midi yoke and "Zyn" standalone), on Linux, to stay in theme with another thread, I'm still having few troubles with the chain PD -> jack -> Zyn.. ;-) But this, I think, is just my lack of knowldge of how audio works on Linux. I'll fight it :-) Alberto Zin

pd -jack -audiodev N eating memory
by Peter Plessas 19 Jun '06

19 Jun '06

Hi List, getting strange startup behavior when specifying -jack and -audiodev 1 together, to avoid having to choose the audio settings after each start in the gui. Looks like this: Pd version 0.39-2 compiled 19:12:29 May 19 2006 peter@gonzo:~/pd_dir/peter_37$ pd -jack -verbose -audioindev 1 Pd version 0.39-2 compiled 19:12:29 May 19 2006 port 5401 TCL_LIBRARY="/usr/local/lib/pd/tcl/library" TK_LIBRARY="/usr/local/lib/pd/tk/library" "/usr/local/lib/pd/bin/pd-gui" 5401 Waiting for connection request... ... connected 269287424 input ports not supported, setting to 32 Segmentation fault (after using up all 500MB Ram, plus all swap space) jackd is version 0.101.1-1 Has this happened to someone else? lg, Peter

[PD-announce] pd-mta 0.1
by IOhannes m zmölnig 19 Jun '06

a tiny UDP-based Mail Transport Agent written in pd can be found here: http://puredata.info/Members/zmoelnig/pd-mta/view dependencies: pd>=0.39 zexy>=2.0 features: only MTA i know that speaks UDP almost(!) SMTP compliant comes with tiny Mail User Agent that can be used with the MTA (well, its rather a "sendmail" implementation than an MUA) issues: only speaks UDP until now SMTP is wrapped into FUDI (which is not SMTP compliant) i wrote it within a few hours because i needed it for a performance (transmitting an email via semaphore flags). i was amazed how fast an SMTP server can be done within pd (after all it is a rather complex software); if the license texts included into the patch are omitted, the patch is less than half the size of the GnuGPL license file. mfg.adsr IOhannes _______________________________________________ PD-announce mailing list PD-announce(a)iem.at http://lists.puredata.info/listinfo/pd-announce

midi prefs OSX
by timon 18 Jun '06

18 Jun '06

Hi, Ive been faffing around for a too long trying to save midi settings/preferences. I have also looked at this in the past without success. Wondered if this is something that has been made more streamlined or if anyone have managed do this on OSX. GThanks, Timon

I forget that the problem of sampled discrete signals is called "foldover", I thought that was "wrapping" like Jamie said. Sorry to keep you busy with my ignorance.

[t3_metro] object is absolutely what I need. It's period has not a minimum acceptable value like [metro]. Their documentation is a bit awkward, but I figured out how to use it. -ugur guney-

You do that with the yellow bar at the top of the help patch. Select which pin, then turn on the yellow toggle. That will turn on output mode for that pin. Now you can send the bitmasks.

Re: BlueTooth CUI : using [comport] or [hid]
by Hans-Christoph Steiner 17 Jun '06

17 Jun '06

Its most like the displaying of the data that is using up your CPU time, if you are talking about CUIBTPDtest.pd. Sliders and other GUI elements are inefficient with Pd on the Mac. You can help the situation by using a [speedlim 100] (from maxlib or cyclone) to slow down the refresh rate. I've been thinking of making a series of graph-on-parent GUI objects that have a built-in [speedlim]. Perhaps it would be better if it was included in the Properties of the object. .hc On Jun 17, 2006, at 2:39 PM, Dan Overholt wrote: > well, I guess it is just my old, slow machine (500MHz G4), but > anyway just > decoding the analog inputs takes 50% of the cpu, and with the digital > inputs also it pegs the cpu... not nice! > > > On Sat, 17 Jun 2006, Hans-Christoph Steiner wrote: > >> >> Hey Dan, >> >> How is the [&] object ineffecient?

Using new features of the new standart version in the old extended version of Pd.
by sokratesla 17 Jun '06

17 Jun '06

# I realized that there are some differences between the original Pd version at http://www.crca.ucsd.edu/~msp/software.html and the pd-extended version, when I started to learn how to use the "graph on parent" ability. Recently there is a pure-data version 0.39.2, and pd-extended<http://sourceforge.net/project/showfiles.php?group_id=55736&package_id=76013> version 0.38.4. In 0.39 you can define the dimensions of the graph at its properties window, but this ability is not in Extended. # Is the version of Pd-Extended 0.38.4, because it is based on standart Pd ver 0.38? # Is there a way to combine old-extended version with the new simple version? (in order to be able to use the advanced graph-on-parent options) -ugur guney-

Printing ALL help documentation
by glerm soares 17 Jun '06

17 Jun '06

I already started this in another thread, but i'll try to be more clear. I was thinking about a script that could take a pd patch window screenshots, without have to open pd. With this, we could make automacally a pdf for example, with all graphic helps of pd externals, abstractions and native objects. I think it could help A lot with a wide vision of the actual state of development. It could be possible do this without have to hack the code ( with some bash shell command or python script for example)?
