Same here but since pd-extended uses the last release of port audio, almost one 
year...

it should work on vanilla if port audio sources haven't been updated.

What is your soundcard? mine is an RME fireface 400.

The idea is about reporting this bug to port audio devs instead.

I guess this is what I was asking. I support a few "block pattern"
partitioning schemes (they're pluggable, its very easy to add a new
one), I could export the choice of these to the end-user, including
the option of what block size to start with - the minimuum block size
of course being Pd's current block size.

My guess is, in the wild, most "pd users" are using Pd-extended, and
ships with a 20msec default delay (dunno if this is inherited from
vanilla, or overridden by the distro, but either way, same effect:
most pd installs probably run at 20msec).

I'm all for allowing configuration of these important parameters, but
I want the external to do something sane out of the box. My guess is
64 sample blocks (~20msec) is more abusive CPU-wise than most people
expect out-of-the-box, so I'm probably going to default to a
partitioning that looks like:

256, 512, 1024, 2048, 4096, 4096, ..., 4096

And allow people to set a different partitioning scheme, including
reducing the initial partition size, if they want. That make good
sense?

Dear Seth,

Another question on similar lines...

Are the DSP calls liable to vary t_signal->s_n (block size) without

handle random blocksize changes, it gets more expensive.
They cannot vary by themselves, but what is usually done (e.g. with 
FFTs), is to place an signal (tilde ~) object in a subpatch and resize 
the blocksize for that blocksize using the [switch~] or [block~] 
objects. You might consider using this very approach.


Also, since convolution is much more efficient around block sizes of
256 or 512, perhaps I should default to one of these, buffer a little,
and have a "runatpdblocksize" message or somesuch?
I still have not understood if/how the user can set the duration of the

scheduled to run at the very last instant they possibly could. If Pd
can have some variance, I can drop the threads and improve the

João and Jonathon,

Thanks for the information.

If you set the canvas size to 1,1 the subpatch shows up about the same
size as the default array canvas size. I done some experimenting with
setting gop with pd-pdsubpatch and not donecanvasdialog but the other
message with fewer arguments. Couldn't you just send the canvas a
message to tell it whether it is a text atom or a graph? I looked
through the code for quite a while but could not find how this could
be done.

I read somewhere that even if gui elements are not drawn in  a

Is this true? How much processing goes on for  gui elements when not visible?

[PD] patch drum sequence editor like micro redrum

[Billy Stiltner]

Hey
I figured I would share this before it get s anymore complicated. It
is  not a complete drum machine sequencer yet only the pattern editing
is done. I figured it would be good to share it as is so you can add
your own drums, triggering, and preset saving.
So far it has a 16 pattern memory with 4 drum channels. The pattern
storage goes into 4 arrays - 1 for each drum channel. Each pattern
array is 256 bytes? Should be 2 bits but hey.

You should add a loadbang to set the initial values of pattern, BANK,
and D_SELECT.
I didn't want to clutter it up for future preset saving.

I ought to be easy to add more pattern memory and more drum channels.

If anyone can figure out a better - less atom way to implement the
color changing of the toggles or anything else in the patch I would be
glad to know.

http://www.geocities.ws/billy_stiltner/music/pd/dmachine.seqed.pd

I have the patch producing drum beats now using sampled drums but need

[PD] creating an engaging interactive art in public space

[Adityo Pratomo]

hi there everyone

Just a normative non-technical question here. I was wondering how would you
guys create an engaging interactive art piece for a public space? I was just
doing a casual internet browsing the other day, looking at various
interactive art in public space, then suddenly that question popped up. I
think that art in public space is very much different with one on gallery or
museum, because people won't have that mind set of actually having an
interaction with an art piece. If so then, what are your strategies to
create one? Are you assuming that people or passer-by will automatically
react to that interactive art? Or is there anything else?

Thank you guys, have a great day :D

Cheers,

I have been using a very recent version of Gem (compiled: Mar 11 2011) for
the pix_record to v4l2loopback feature (thanks Iohannes, It's working
great!). But, the pdp2gem object is  not working at all, while pix_2pdp
works ok. (version "gem2pdp v0.7"). That's with pd vanilla (0.42-6)

If I use pd-extended (maverick stable), pdp2gem works ok, but only with the
pre-compiled Gem version (compiled: Sep 22 2010). So, I 'm wondering if
could be a new Gem compatibility issue, anyone can help me on that ?

Thanks in advance

Cool, thanks.

I see some creator names and classes I never noticed before:

fswap: alias for swap (I just added this fact to swap-help.pd)

Anyone have help docs (or helpful comments) about the following?

[PD] ANN: upcoming L2Ork performances and a new pd-l2ork software release

[Ivica Ico Bukvic]

(apologies for cross-posting)

Dear Friends and fellow L2Ork and Pd enthusiasts,

I would greatly appreciate it if you would please distribute the following 
announcement.

The spring is in the air, which means it is time for the spring DISIS 
(http://disis.music.vt.edu) and L2Ork (http://l2ork.music.vt.edu) events. To 
start the season right, this past Friday L2Ork had a sneak preview performance 
at Roanoke College. More so, this coming weekend we are having a truly special 
series of events with the return of the Boys & Girls Club laptop orchestra whom 
we've been working with this semester. In addition, the spring DISIS event will 
also include guest artists and scholars Ron Coulter, Brad Garton, Peter Kirn, 
and Dave Phillips. The upcoming events include:

Thursday April 7 @ 3:30-4:45pm in DISIS presentation by Brad Garton
Friday 10am-1pm lectures in the Arts Armory by Brad Garton, Peter Kirn, and 
Dave Phillips (free admission)

Friday April 8 @ 7pm in Dumas Center (Roanoke, VA) children's concert featuring 
Boys & Girls Club laptop orchestra and L2Ork

Saturday April 9 @ 7pm in Squires Recital Salon children's benefit concert (an 
Arts Fusion event) featuring Boys & Girls Club laptop orchestra and L2Ork 
followed by a hands-on laptop orchestra demo session for kids and families ($5 
general, $3 children/students/seniors, with all proceeds benefiting Boys & 
Girls Club)

Saturday April 9 @ 8pm in Squires Recital Salon benefit concert (an Arts Fusion 
event) featuring Ron Coulter, Brad Garton, Peter Kirn, Dave Phillips, and L2Ork 
($5 general, $3 children/students/seniors, with all proceeds benefiting Boys & 
Girls Club)

This year we've also partnered up with the Virginia Tech Kids' Tech University 
program to expand our outreach to young audiences. For additional info on the 
upcoming events, please visit our Events page or our Facebook Event page 
(http://www.facebook.com/event.php?eid=136468179758733). To keep up with the 
latest updates, join us on Facebook 
(http://www.facebook.com/group.php?gid=117918141555131).

As if that weren't exciting enough, earlier this weekend we've made yet another 
public release of pd-l2ork (http://l2ork.music.vt.edu/main/?page_id=56) with 
even more cool features and fixes (changelog: 
http://l2ork.music.vt.edu/data/pd/Changelog). Our site has been also updated 
with the new promotional materials and photos. Yet, in the spirit of Steve 
Jobs' keynote speeches we've left the best for last. Stay tuned for more 
exciting updates soon ;-)

Re: [PD] Data Structures GOP and installing latest PD

[João Pais]

I didn't know you could GOP data structures.
This opens up a new world.
Where is an up to date tutorial on using data structures?


you can use gop with any graphical object. you can see some objects of my  
"library", jmmmp at pd-extended/extra - like [sliders], [swatch] or  
specially [bezier]. there are some bugs, like in [bezier] if one of the  
control points gets out of the gop area, the data strucutres stop  
responding to the graphic input; but they still keep working.


one other thing is the scaling, usually the data-s takes the whole canvas  
of the gop patch, but appears correctly. also, since data structures can't  
be saved using $0-variables, if you want a dynamic, multi-use patch, you  
might need to do some trickery, like generating the scalars with loadbang.


etc. etc... maybe people will start using them now and then more often, if  
they see how useful they can be.

 The Pd window filtered 3 lines

 I tried setting the path but whatever I add isn't saved when I quit.

 So far this is not very useful...

 Does anyone actually have Pd-0.43 working?

I just installed 0.43 in windows 7 64 bits. I have a problem with
Asio. I have a soundcard with his own asio driver, if I choose asio in
pd it doesn't works.
Any idea how to configure it?
thanks

Btw, had you tried DesireData's auto-completion ?

2. with short descriptions in 15 languages

3. can pick from popup list using arrow

there were some more improvements after (3) to make it look better.

That's something I started to write in 2004, and Chun Lee improved it in
2006 or 2007.


hi
no I never tried it (when I discovered it back in the years, my linux 
knowledge was close to null and I thought that the project was dropped 
(for some reasons..))

it always looked amazing to me, congrats ! (as well as gridflow)

I had to use pd again not long ago and thought that I should try to code 
these goodies for the sake of patching faster and with (nearly) no mouse 
(although I hate tcl, gui-plugins are cool =)


I'll give a try at desiredata and let you know.

cheers,

Btw, had you tried DesireData's auto-completion ?

1. just name suggestions
http://artengine.ca/desiredata/gallery/completions.gif

2. with short descriptions in 15 languages
http://artengine.ca/desiredata/gallery/completions2.gif

3. can pick from popup list using arrow
http://code.goto10.org/projects/desiredata/attachment/wiki/UserDocs/dd_comp.png

there were some more improvements after (3) to make it look better.

That's something I started to write in 2004, and Chun Lee improved it in 
2006 or 2007.

I don't know of an up-to-date tutorial, but there is a tutorial in 
doc/4.data.structures.  Some parts are out of date:

* data is, in fact, persistent when using scalars.  Data is saved along 
with the patch. (Similar to using a "Put" menu array and checking the 
box for "save contents", except that with scalars they always save with 
the patch.)
* the term "template" is used both to describe the subpatch in which the 
data structure ([struct] + any drawing instructions) is defined as well 
as the [struct] object itself.  (I think [struct] used to be named 
[template]...)
* some of the mouse-driven messages (e.g., "click") didn't exist when 
those tutorials were written.  For an up-to-date list see struct-help.pd 
in:

http://pure-data.svn.sourceforge.net/viewvc/pure-data/trunk/doc/pddp/

(all the data structure related objects like [plot], [element], etc. have 
updated documentation if you use the pddp docs from the link above.)

[PD] Data Structures GOP and installing latest PD

[Billy Stiltner]

Hey

I didn't know you could GOP data structures.
This opens up a new world.
Where is an up to date tutorial on using data structures?

I'm about to install PD 0.43. I have a test4 version installed as well
as pdx 0.42.5 and vanilla 0.42.5.
I have a couple of libraries loaded with vanilla - GEM and GGE. How
will the new version efect these installations?

Also on LINUX I have with UBUNTU studio 10.10 pd 0.42.5 with all the
exts available and then on puredyne I think my vanilla installation is
messed up because I had to edit the config files to get pdL2ORK to
run. Should be fine if I just replace the config files with the
originals.

Where is some god documentation on installing multiple versions of PD.
What should I look out for when using so many different installations.

it could be that the decoding backend does not support alpha channels.
i'm pretty sure that recent versions of Gem with gmerlin do support 
alpha (at least i remember having spent some time for that).

if you can provide a (short) video with alpha i could test.

[PD] pix_film alpha in Linux

[Matteo Sisti Sette]

Hi,

I'm trying this:

[pix_film]
 |
[pix_texture]
 |
[alpha]
 |
[rectangle]

I'm using some videos that have an alpha channel and I had tried them 
previously in Windows and Mac and they were rendered correctly with 
their transparent background.


Now I am trying the same in Linux and the videos are opaque, as if they 
didn't have an alpha channel or as if they had an opaque black background.


I've already tried sending "colorspace RGBA" to pix_film, but nothing 
changes.


I'm almost sure the videos were encoded with the Apple Animation+ 
encoder but if i right-click them in Ubuntu and select "properties" it 
says "run-length encoder". What is sure is that i tested them in Windows 
and Linux and used to work.


Any idea?

thanks
m.

hey thanks for spotting this.
they are already in the global list of pd internals but I didn't notice 
that they had underscores instead of spaces.

I fixed it directly in the main list and it will be on the next version.


Is there no way to just get a list of all the creator names that are

I'm afraid not :/
but you can manually add your favorites or missing/special ones in the

I'm trying to think if there is a way to keep or get the coordinates of

hi Hans
dunno if this is the same for you but for me there are some issues with 
this (on Archlinux + fluxbox):


- the popup is created at "screen coordinates" and not patch window 
ones, i.e. if the object box is at 100x25 (from the top-left patch 
window), the popup appears at 100x25 from the top-left corner of my 
whole screen, which I find not very intuitive


- also, if you are creating an object with CTRL-1 and moving your mouse 
(no click), the coordinates don't update (but that's not that bad)


anyway, all these are the reasons why I dropped the popup option (which 
would be better IMHO).


I'll think a bit more about it in the next days.

Chun,

This is awesome. I've never heard PD used in this way. Sounds like PD
micro/chipmusic. Very enjoyable.

weird, is it still the same? I just tried downloading the ogg and seems 
fine, as well as the link above. I am not sure what it could be, but let 
me know if it persists..

häh?
a few months ago, there was some beta-version of Pd available for
download (named "0.43.0test3" or so).
in the meantime, 0.43 has been officially released.

i would say that the main difference between a "test" (aka 'beta')
version of a software and an official release is, that the maintainer(s)
think that all the showstopping bugs have gone away.
(i also hope, that the maint's toughts are not the _only_ difference,
but that showstopping bugs have indeed been fixed).

if you don't trust in official releases, then you probably have to check
yourself, whether a given version fulfills your quality standards [*].

[*] i'm aware that you personally do a lot of testing of 'experimental'
software, as can be seen in the bug-tracker. thanks for the reports, btw.
