A closebang would solve this. It will probably happen less often with local

Storing data is not in the realm of sssad - again this is by design and comes
from my experience with  RRADical/Memento where the storage was inside the
saving system and tied to [pool].

SSSAD is intended to to just one thing but do that right: Its purpose is to
eavesdrop on the messages that objects send to each other and distribute them
to rsp. modify them from a central place. That's all. What comes after that
central place is up to the end user. It would be easy to make an external that
does the same. sssad is just a wrapper around [list], [route] [send] and
[receive]. One "S" in its name stands for "simple". ;)

Hm, I don't understand this question? RjDj is pretty much pure Pd and has
almost no externals at all - which doesn't mean that you can't do much with it:
For audio work Pd is very powerful and no externals are (strictly) necessary.

Hehe, I guess that's because you filter noise: It's harder to recognize the

Elliptic filters are rather hard to design, most of the time you will find
Butterworth or Chebyshev designs in our little audio world. 

A biquad~ has only two poles and zeroes, so you would need to cascade several
stages to get a really sharp filter.

Yes, that's true. rjlib has its focus on audio and control abstractions to be
used on mobile devices with vanilla Pd. Some of this fits into a "all purpose"
library, but a lot of it doesn't.

One thing that occurs to me is that the quality of the reconstructed
sound has more to do with the interpolator rather than the sample
rate.

The actual output is an analog signal which is obtained by
interpolating samples.  Most audio systems use linear interpolation,
which has characteristic spectral characteristics.  A low-end or
possibly obsolete system may use sample-and-hold rather than
interpolation.

Probably, there's a high-frequency "sizzle" that you want to emulate
here.  To get that full sound (an analog signal), there's a freq
domain transformation that should work.

It comes from the linear interpolator.  It actually leaves some sound
in the range from 14kHz to 22.05kHz.  To reproduce the effect, you
would fold over frequencies from 5.95kHz to 14 kHz into 14kHz to
22.05kHz.  Then you would apply the spectrum of the interpolator,
which will reduce but not eliminate the high frequencies.

I haven't worked it all out.  That's as far as I got this weekend.

[PD] Mouse Control...

2009-03-16 Thread Simon Ball

Hi there

I'm having trouble realising an idea. I've got the software running (mac
book pro) and managed to play with some of the examples, however I am new to
PD, so bare with me!

I'm trying to generate a composition of images that float in 3D space. I
want the images or layers to move and rotate towards areas of a screen where
movement is detected. I don't need to track specific points of motion,
simply to judge where movement is taking place. I think this will involve
reading frames and analysing changes in pixels. Does that make sense?

I plan to use a mini DV camera to run this, on a high contrast background,
although I've seen a similar method of recording movement with a webcam and
processing, which worked pretty well. (
http://vimeo.com/1948430?pg=embed&sec= - tracks changes in pixels, although
I'm not sure how).

I assume that this will involve some sort of trigonometry to move images
towards points where motion is detected, although I'm not sure how to apply
this in PD. Also, how to I generate a floating effect, much like 'easing'
does in animation software. And can this work with 3D, mapped images in PD?

I hope thats clear, if a little broad, let me know you need any further
info.

Thanks in advance for any suggestions/solutions.

Simon

You are right.

I find IRC meetings to be very unproductive.  Everyone is usually too  
busy multitasking to get anything done in the meeting.  I think that  
the high bandwidth of voice and seeing the person holds your attention  
longer, so there is less multitasking and more focused discussion.   
That said, if the audio connection is bad, then it gets worse than  
IRC.  IRC is good for asking pointed questions back and forth, better  
than audio/video chat.


I think we should have IRC running, but also it would be great to have  
video chat with projectors, speakers, and a decent mic setup.  Marius  
and I ran the streaming for a class at Brooklyn Poly.  One student was  
joining in from Canada.  When it was set up and running well, it  
actually worked quite well.  This means spending a little time setting  
up the speakers and mics, and a projector is good too instead of a  
screen.  Since this will be happening over three days, it makes sense  
to spend some time on setup.  ITP can provide all of the equipment on  
the NYC end.

we used iChat for these sessions, and usually there were 3 streams
involved. if more than one person is involved on one side, you really
have to put some focus on the audio aspect, like using microphones
that can be passed around.

Re: [PD] Pd book sprint in NYC/Berlin

i am really unsure what you are talking about.. a meeting is what it is, and 
the medium will never dictate what you are talking about and the intensity 
with which it is conducted.. perhaps face to face contact is good for 
watching the iris quiver and building a psychological profile based on that 
particular interaction, but really the amount of focus and dedication that 
anyone gives to a subject is dependent on variables that are quite out of 
control to other participants.

in terms of multi-tasking... i am usually engaged on a number of things in any 
given time period.. what at least is consistent about IRC is that i can chose 
to focus on any given problem without having to make myself publically 
withdrawn from the discussion, and in such a circumstance i have a log to 
refer to what i have missed.. 

which leads me to my final point.. i have a log.. which everyone does, without 
transcription, without poor pronunciation and bad language getting in the 
way.. easy to archive and so on.. 

i have no real interest in the topic, but i have been a particpant in 
enough 'online meetings' to know that video conferencing is a complete waste 
of time, beyond the initial distraction of connectivity issues.. 

if people have something valid to say and real-time is the only productive 
forum then IRC works and works well, otherwise voice probably makes up for 
where text lacks, but only in small groups.. video is just an unnecessary and 
unproductive formality.. 

meetings are never as productive as the facilitato

Re: [PD] Mouse Control...

hi simon and welcome to the pd community.. 

it's a decent question and you will no doubt get a number of different 
responses.. 

depending on your system you have a few options: gem, pdp or gridflow, which 
all cover the imaging section of your question. gem however is probably the 
most appropriate as it covers both the 3D and the interactive part in one. 
gem allows you to interact with image, video and GL primitives in a 3D 
space.. it also covers input and depending on how you require live imagary to 
be captured you have varying levels of control, for example there is 
[pix_blob], which describes the average mass (gravity) of movement in terms 
of X+Y (which sounds like what you're after), there is [pix_hit] which allows 
you to describe parts of the image grid which trigger when the input passes 
through, or there is [pix_dump] which outputs the incoming pixel grid as a 
list which you can process with your own math. 

as for your camera, it should be supported by gem, but DV support can be a bit 
sketchy on some platforms.. 

gem is part of the pd-extended build which runs on many systems.. 

this is a fairly broad answer to a broad question, i hope it helps..

Re: [PD] change samplerate locally

2009-03-16 Thread hard off

>>One thing that occurs to me is that the quality of the reconstructed
sound has more to do with the interpolator rather than the sample
rate.<<

i have a feeling that because the synth has non-bandlimited oscillators,
that the sample rate itself is pretty important, or more importantly, the
aliasing effect it has is very important.  i think that that reason why
28khz is sounding 'better' than 44.1 is because of more high frequencies
folding back over and thickening the sound up in the low end.

i could be totally wrong, but that's what it sounds like.

44.1khz is 'thin and wimpy', but at 28khz it's a thicker, fuller sound.

Re: [PD] Midi in with arduino

2009-03-16 Thread martin.peach


> Does anybody know how to wire a midi in on to the arduino.

See the attached schematic. The Rx pin is whichever digital input on the 
Arduino you are using. The two MIDI wires are pins 4 and 5 of a DIN-5 
connector. You must not connect the ground (shield or pin 2) from the MIDI 
cable. R2 and D1 are there to let you see the data as it arrives by flashing 
the LED, so they're not essential.

i had a minor breakthrough.

upsampling my signal path, by using [block~ 64 1 2] has the same effect on
the sound as lowering pd's global sample rate to 22050.

not perfect, and to me it defies logic, but certainly a lot closer to the
28khz sound than the 44.1khz sound was getting.

Re: [PD] steep filter?

I looked in my list of pd-ext objects, but found no elliptic filters.  
are
there any, or any way of getting their coefficients to use with  
biquad~?




Elliptic filters are rather hard to design, most of the time you will  
find

Butterworth or Chebyshev designs in our little audio world.



hey, joão
you still haven't made friends with fft? ;)
i've just finished a max external that does chebyshev filtering with a  
variable number of poles and adjustable % of ripple in the passband.  
repackaging this into a pd external wouldn't be too hard.
if you are interested in trying this out, drop me a mail and i'll see  
when i can get it done.

volker.


ah ah, that's true. actually I didn't need anything so far that *had* to  
be done with fft, so I never learned it properly (just unproperly a couple  
of times, like yours, in which I didn't exercise afterwards).


of course I would be interested in the filter, as well as the rest of the  
community should be. don't make any rush because of me, because it can  
happen that after a while I don't need it anymore (in case you're too busy  
with something else). but if you want to join your code to pd-ext,  
everyone will be happy. (and windows compatible, please)

Marshall McLuhan would strongly disagree with you, as do I.  The  
medium with which you communicate has a very strong impact on the  
conversation.  That does not mean that it is the only influence.   
There are many things that lead to a bad meeting, and from my  
experience of having many meetings in person, on IRC, on IM, on  
phones, on voice chat, on video chat, and many different mixes above,  
I am a strong believer in high-bandwidth communication like voice.

which leads me to my final point.. i have a log.. which everyone

way.. easy to archive and so on..

i have no real interest in the topic, but i have been a particpant in
enough 'online meetings' to know that video conferencing is a  
complete waste

of time, beyond the initial distraction of connectivity issues..

if people have something valid to say and real-time is the only

That said, if the audio connection is bad, then it gets worse than

video chat with projectors, speakers, and a decent mic setup.  Marius

up the speakers and mics, and a projector is good too instead of a

to spend some time on setup.  ITP can provide all of the equipment on
the NYC end.

C::NTR::L is a "software", naturally Pd-based, for audiovisual live

instrument in an augmented tool to control real-time audio-video processing,

Why is morning here easier to sync up with there? I don't get it

What time are people thinking of starting in Berlin?  I am trying to 
organize the space in NYC.  Will this be a morning thing there?  If so, 
that's easier for NYC time to sync up with.  But that's not essential.

2009-03-16 Thread Phil Stone

This is very impressive, Marco. What grabs me immediately is that you 
are demo'ing with bass (nice Steiny or Hohner, btw) - lower-frequency 
instruments are particularly difficult for pitch-detection.  What is the 
latency?  It's hard to tell from the video, but it looks pretty 
responsive.  How accurate?


I've been waiting a long time to plug my bass into my Pd stuff.  I will 
be happy to test anything, and also to help with the code cleanup, if it 
lies within my area of competence.


Nice work!

hi list,

I am pleased to announce that the big pd tutorial I wrote in the last 
years with the help of a grant by the Music University of Freiburg / 
Germany, is now online, in english and in german.


It is also available as a book (paperback) at Wolke Publishing House, 
where the "bang" book was released.


At the moment, Amazon says that it's not available, which is strange 
because it's definitely released, but at least it can be purchased at 
the Publishing House itself.

Re: [PD] Pd book sprint in NYC/Berlin

Is this a one time thing, or might happen more times? I would say that at  
least voice connection would be productive. I haven't that much experience  
with video conferencing, but a medium where people can react at the same  
time they can think would be important. (although after too much time,  
even the fingers are faster than some heads)


How about voice connection for general talk + an irc chat for small, fast  
questions? We can also send a group foto with skype, so that everyone  
feels the warmth.



Marshall McLuhan would strongly disagree with you, as do I.  The medium  
with which you communicate has a very strong impact on the  
conversation.  That does not mean that it is the only influence.  There  
are many things that lead to a bad meeting, and from my experience of  
having many meetings in person, on IRC, on IM, on phones, on voice chat,  
on video chat, and many different mixes above, I am a strong believer in  
high-bandwidth communication like voice.

Re: [PD] Mouse Control...

Video tracking is tricky, but the basics are not too hard. In the Pd-
extended Help Browser, check out these patches:

manuals -> 2.Image -> 17.tracking.pd
examples -> Gem -> 04.video -> 03.movement_detection.pd

I am guessing the first is the one you want, its based on background
subtractions, which is a widely used technique.

Hi there

I'm having trouble realising an idea. I've got the software running
(mac book pro) and managed to play with some of the examples,
however I am new to PD, so bare with me!

I'm trying to generate a composition of images that float in 3D
space. I want the images or layers to move and rotate towards areas
of a screen where movement is detected. I don't need to track
specific points of motion, simply to judge where movement is taking
place. I think this will involve reading frames and analysing
changes in pixels. Does that make sense?

I plan to use a mini DV camera to run this, on a high contrast
background, although I've seen a similar method of recording
movement with a webcam and processing, which worked pretty well. (http://vimeo.com/1948430?pg=embed&sec=
- tracks changes in pixels, although I'm not sure how).

I assume that this will involve some sort of trigonometry to move
images towards points where motion is detected, although I'm not
sure how to apply this in PD. Also, how to I generate a floating
effect, much like 'easing' does in animation software. And can this
work with 3D, mapped images in PD?

I hope thats clear, if a little broad, let me know you need any
further info.

Thanks in advance for any suggestions/solutions.

[allow] is in maxlib, [active] is in cyclone. The screenshot probably shows a
modified intro.txt, that doesn't separate between internals and externals
(which makes patching for pd-vanilla a bit harder)

Congrats on finishing it Johannes.
This looks very nice. Some people ask if my book 
focuses on sound design, and Millers book focuses on
DSP theory, why is there not a book dedicated to
composition in Pd? Well now there is. (and Todd Winkler
"Composing Interactive Music" but that is quite
a 'conceptual' level and uses the non-free Max)

I had the opposite problem, Amazon were listing mine as available
and taking orders AFAIK, but it isn't actually available there
(because it would cost too much).

With so many good things happening on the docs front nobody
can say Max has better documentation any longer, Pd has a
great choice covering a range of applications and abilities.

[PD] pidip compilation problem

2009-03-16 Thread marc widmer


hi list

i have to compile pidip from source (on ubuntu studio 8.04) because i 
have a project where i depend on some changed files.


after a year of not touching the library (never change running system) i 
had to move everything to another system and therefore need to recompile 
pidip. first i tried to use my old pidip sources, after running into 
troubles with (quicktime and lqt) which i could solve. compilation 
stopped when pdp_capture should be compiled:


pdp_capture.c: In function ‘XMyClientWindow’:
pdp_capture.c:129: warning: implicit declaration of function

‘pdp_packet_pass_if_valid’ from incompatible pointer type

make[1]: *** [pdp_capture.o] Error 1

after this i tried to compile from svn, again i had to outcomment 
libquicktime issues (though there was already a condition included in 
the modules source, whicht was somehow ignored)



add the end again i ended up with problems compiling pdp_capture
make[1]: *** No rule to make target `...@pdp_capture_object@', needed by 
`all_modules'. Stop.
make[1]: Leaving directory 
`/home/metafor/Desktop/puredata-externals/externals/pidip/modules'

make: *** [pdp_pidip_all] Error 2

i guess because old and new pidip are not compiling i miss something 
with a library (is it this libquicktiem problem?), but as configure went 
fine, i am not sure which one is missing/or wrong version, has anybody 
run into these troubles as well? what am i doing wrong?


well, any help is apreciated.

It is also available as a book (paperback) at Wolke Publishing House, 
where the "bang" book was released.


At the moment, Amazon says that it's not available, which is strange 
because it's definitely released, but at least it can be purchased at 
the Publishing House itself.

Re: [PD] Unified Library was Re: Call for GSoC mentors! March 9th deadline!

2009-03-16 Thread danomatika

yeah sorry frank, i should have explained more clearly.

i also think that no GUI is the way to go for functional
abstractions.  that
was the big flaw of the DIY library i did, that the function of
the
abstractions was tied in with the gui component.  i did it that
way because
i didn't want to clutter the namespace with too many
abstractions, and the
thought of one abstraction for function, and then a different
one for GUI
was not appealing at the time.

but now, i think that is the only way to go.  like, as you said,
for
polyphony.  and then also for the many many cases in which you'd
want to
build your own gui for custom control.

i do think you guys have got a really really strong system there
with
rjlib.  but i was just saying that without the gui stuff, it
doesn't exactly
fit into being that 'all purpose building blocks' library that
we are
discussing.


This is where the pd-mtl convention makes so much sense ...

Core functionality is made into patches with an underscore at the end of
the name and the regular name is just
a gui wrapper around it.  I've started using the approach in the
rc-patches and, as Frank said before, it makes
building larger gui objects much simpler.  The right inlet takes all the
control whenever possible using name messages.

So rc-chorus~_ is a regular object and rc-chorus~ is a gui wrapper with
SSSAD.  So if you want SSSAD you use the gui.

this looks likely to be a brilliant reference, very balanced language, not too 
patronising and not too convoluted. it presents a number of complex methods 
in a straight forward manner, but with enough depth to really build upon.

many congratulations johannes and please pass on my praise to your translator 
mark barden, who has also done an excellent job.

Re: [PD] pidip compilation problem

2009-03-16 Thread ydego...@gmail.com


ola,

what was you configure command ?

./configure --help
 --enable-capturecapture optional object ( only works with 
Image Magick <= 6.0.7 )


this became optional ...
in a way deprecated...
it would not work  with most recent  Image Magick..

xiaoo,

hi list

i have to compile pidip from source (on ubuntu studio 8.04) because i 
have a project where i depend on some changed files.


after a year of not touching the library (never change running system) 
i had to move everything to another system and therefore need to 
recompile pidip. first i tried to use my old pidip sources, after 
running into troubles with (quicktime and lqt) which i could solve. 
compilation stopped when pdp_capture should be compiled:


pdp_capture.c: In function ‘XMyClientWindow’:

make[1]: *** [pdp_capture.o] Error 1

after this i tried to compile from svn, again i had to outcomment 
libquicktime issues (though there was already a condition included in 
the modules source, whicht was somehow ignored)



add the end again i ended up with problems compiling pdp_capture
make[1]: *** No rule to make target `...@pdp_capture_object@', needed by 
`all_modules'. Stop.
make[1]: Leaving directory 
`/home/metafor/Desktop/puredata-externals/externals/pidip/modules'

make: *** [pdp_pidip_all] Error 2

i guess because old and new pidip are not compiling i miss something 
with a library (is it this libquicktiem problem?), but as configure 
went fine, i am not sure which one is missing/or wrong version, has 
anybody run into these troubles as well? what am i doing wrong?


well, any help is apreciated.

cheers

Hm, you all are so fast readers, reading a book in less than one evening. :)

By quickly scanning through the book and grep'ing the patches, I wonder, why
not a single patch uses the [list] object which - not only because of the
[list]-abs - is one of my most often used objects especially for composition? I
would expect a section on list-processing when teaching people how to compose.

Anyway, I haven't read it yet, maybe these topics are presented without [list].
