Re: [PD] reverb for each grain

[Kevin McCoy]

Not to mention, I hope you'll be showin' some clips of whatever you
come up with... doing something like this is something I have had in
mind for a while and I would love to hear the results you get!  Are
you thinking it can make the grain cloud more "dimensional" this way?
That was the idea I had..

Re: [PD] reverb for each grain

[hard off]

well, as charles suggested, set up a few different reverbs of varying
decay lengths, and send varying percentages of each grain to the
different reverbs.

also, reverb usually has a 'dampening' setting, which will dull the
signal as it goes through, so another thing you can try is to mix in a
lowpass or bandpass filter after every voice before it goes in to the
reverb.  if you alter the dry/wet ratio of each voice going into the
filter, as well as altering the cutoff and q values for each filter it
will make it sound similar to if each voice were going through a
different reverb.

Re: [PD] gpl vs creative commons

[marius schebella]

at the moment the discussion is theoretical because it is not possible 
to close-source a pd patch.

the original question (whether a pd patch is a piece of software or a 
piece of artwork - gpl/bsd vs cc) was not really answered.

and then - what about abstractions? under which license are for example 
the pdmtl abstractions released?

the big overall question is how to deal with intellectual property. do 
we as a society/community want to protect it? of course everybody likes 
sharing, but I don't think communism worked out well after all.

 i guess, if you have a  patch that depends on a GPL'ed pdlib, and you 
 are distributing your patch with this library (e.g. for convencience 
 reasons), then you are kind of _statically linking_ and thus your patch

Re: [PD] reverb for each grain

[Charles Henry]

It is an interesting idea...
and 64 reverbs is too many, no matter how you do it.  Derek's idea is great!
I would just add to it, that you could use just a few voices to cover
the range of different settings of re-verbs and pan the grains between
the voices (effectively a linear interpolation between reverb effects)
to give each grain an unique reverb sound.

Re: [PD] reverb for each grain

[hard off]

64 seperate reverbs is gonna be hard for any cpu, regardless of which
reverb algorithm is used.

may i suggest that an alternative is to send your grains through the
same reverb, but to alter the amount of each grain that gets sent into
the reverb.  so, for example, grain 0 is sent 100% to the reverb,
grain 1 is sent 90% to the reverb, and 10% is passed on dry, grain 3
is sent 10% to the reverb and 90% is passed on dryetc

if think of reverb as the sound of a room, then the mix % is the
position of the object in the room.

[PD] reverb for each grain

[punchik punchik]

hello, im working on a 64 voice granular synthesis
tool.   

i want to apply a reverb effect   to each grain independently. 

which is the best way of doing this?
which reverb do you recomend me to use? i was trying
freeverb but it consumes too much cpu. and 64
freeverbs makes my computer go slow.

and which is the best way to achieve this in terms of
cpu consumption?
is it better to have 64 abstraccions, or 64
subpatches?


thanks

Yes, I spoke too curtly. The first line of that answer says "When the
interpreter just interprets a language, the answer is no. The interpreted
program, to the interpreter, is just data; a free software license
like the GPL, based on copyright law, cannot limit what data you use
the interpreter on. You can run it on any data (interpreted program),
any way you like, and there are no requirements about licensing that
data to anyone."

To my mind, this is the important bit for Pd. It doesn't matter what you
link the Pd binary with - it is interpereting patches and they themselves
aren't linked to GPL code (in my mind anyway).

I guess you could argue that instantiating a GPL external in Pd is like
the case of Python's ctypes module, where you actually dynamically load a
library and expose the API to your interpereted code itself - calling
functions within the library from your script. I believe this requires
you to release your interpereted code under the GPL if the library you
are dynamically loading and linking your code with is GPL. But in my
mind, a GPL external is more linked into Pd itself, which then uses
that linked library to help interperet the Pd patch. So, in short, I
dunno 100%. I would be more likely to err on the side of saying that
you don't have to release your Pd patch GPL just because it uses GPL
externals. That seems like a really weird restriction to me, but I might
be wrong.

Yep, completely correct. So what it's basically saying is that if you
use a GPL abstraction in your patch, then your patch must be GPL. That
makes perfect sense to me. It doesn't say anything about externals
though, and the question there is more complicated because the external
is actually linked with the Pd interpereter itself, not with your patch
(or is it?). I still don't think it's required that you release patches
GPL just because you use a GPL external.

Of course statically linking doesn't define ownership. I like to think
that what I said was funny and would be considered as a joke, but that
is probably quite a stretch and I should go back to comedy school. Sorry
for confusing the issue!

Basically all you need to do is add up all previous segment lengths to
get the delay for the next segment. Like attached (for a start). Note
that while in Csound, the duration comes before the target, the
attachement still has the duration after the target, in sync with
line~ and vline~.

hm.. depends on how strictly you define 'one message'. yeah, it is
perfectly possible to make a [vline~] based ADSR generator without using
[del] and [list split] trickery and by using only one message box, but
you are right: in this message box you need several comma separated
messages (so: it's not possible with literally 1 message). usually you
don't know the length of the key pressure in advance, but for
simplicity's and illustration's sake let's assume we know it (T=280ms)
beforehand:


/\
   /  \_
  / \
 /   \
/ \

A=50ms S=0.6R=30ms 
 D=20ms   

|<- T=280ms   ->|


[0, 1 A, S D A, 0 R T(

which is:

[0, 1 50, 0.6 20 50, 0 30 280( <- one message box, four messsages
|
[vline~]

or you could replace the variables actually represented as letters by
real pd variables (A->$1, D->$2) and you would get a real adjustable
ADSR envelope generator with subsample accuracy ;-)

Re: [PD] one more boring computation-time cuestion of mine...

[Charles Henry]

Another diagnostic idea: try comparing the behavior during loading
with audio switched on and off.
my guess is:
if this is a memory issue, it won't make a difference
if it's the computations involved with big #'s of tabplay~, then it
will be faster with audio off

Yeah. Thats what i'm hoping too.

Last year the web casting team said they had thought about it, but  
couldn't do it due to their limited budget. I have no idea how to  
suggest this idea to the 2008 team.

I recall watching a videocast of Dafydd doing a talk on Pd at some  
canadian FLOSS meeting-conference-something. It was my impression it  
was a really good talk and presentation of Pd and what Pd could be  
used of. But sadly it was almost useless as i could se what was going  
on at the screen.
Last years LAC wasn't too bad as the slides used were published as  
PDF and it was announce on IRC when there was a page change. Problem  
being that many presentations include things in the screen video that  
is not slides. This could fx. be a running Pd patch (as Miller did a  
lot at ICMC07).

Re: [PD] vline~ question

[Kyle Klipowicz]

Haha this conversation is hilarious! Thanks for keeping it so lively everyone.

I may be suffering from Csound-itis. I want vline~ to basically act
like the linseg Csound opcode:

kr  linseg ia, idur1, ib[, idur2, ic[...]]

Where each segment is defined as points in time connected by a linear
ramp. It seems easier to me mostly because it's the first programmable
linear envelope generator that I was exposed to.

Perhaps just making a [linseg~] abstraction out of vline~ using the
previous suggestions on this thread would suffice. I definitely do not
want to limit the sustain possibilities of vline~ as a sort of ADSR
envelope generator. I just want to do what Steffen said. After all
this banter, it's probably easier for me to just remember what the
third tuple is in the comma separated messages.

However, I don't think it's possible to make a playable ADSR generator
with vline~ using only one message anyway. I think that it would still
have to be somewhat hacked together using some triggers and delays etc
like the ADSR example that Miller included with Pd. Am I wrong here?

Thanks again for participating in the thread!

Re: [PD] one more boring computation-time cuestion of mine...

[Matteo Sisti Sette]

> Just a guess... maybe allocating all that memory is forcing the OS to
> page other apps out.

I can't discard that, but...
Correct me if I am wrong: if that was the case, removing the [tabplay~]s 
shouldn't make a difference, should it?

I removed the tabplay~s but the number of tables and size of the sound 
samples are the same, and now it loads all samples much much faster.

To "rephrase" the whole problem in a simpler way, consider this:

A) N occurrences of:
[table table-K][soundfiler]

[tabplay~ table-K]

(with K=1,2,...,N)

Versus this:

B) N occurrences of just [table table-K] and [soundfiler]
and only one unique [tabplay~].

When I "load" samples, each soundfiler receives a
[read -resize something.wav table-K( message.

In case (A) loading all samples is much slower.


My guess was the following:
"Every time a soundfiler loads a file into an array, and therefore resizes 
it, the DSP graph (or SOMETHING) is recomputed. In PD's data structures, for 
some reason each table has some sort of link to any [tabplay~] or [tabread~] 
object "attached" to it (in this case one tabplay per table). So when 
recomputing the whole data structure (once per table resize) there's some 
kind of operation that is being done N times in case A and zero or one times 
in case B."

 Or maybe the first part is correct and the second part is much 
simpler?:
"Evert time a soundfiler loads a file into an array, and therefore resizes 
it, the DSP graph is recomputed, and the time needed to do this is 
proportional to the number of  existing "~" objects. Therefore removing a 
big number of useless [tabplay~]s is reducing the size of the graph and time 
needed to calculate it."


Is any of my two guesses even near to correct?

Thanks a lot
m.

All LAC2008 design is by an ex-student of KHM: Christoph Haag. Also
the logo, which will be available as a t-shirt during LAC.  The
Cologne-based minimal techno label "Speicher" (sublabel of Kompakt)
also used a variation of the city arms as its logo[1]. May be a
tradition by now ...

Btw. the LAC poster you can print yourself, of course, using the
downloadable PDF on the site [2]. It is a piece of generative art:
Each download is different. (well, almost)

Re: [PD] one more boring computation-time cuestion of mine...

Just a guess... maybe allocating all that memory is forcing the OS to
page other apps out.  (I'm not sure how much memory is getting used but
if it's more than 1/4 of the system total it's possible that is slowing
stuff down.)

Yes, and they are also technically in violation of the GPL, AFAIK.  I  
imagine that Linus and the FSF has not enforced it because it could  
be counterproductive.

yeah; i wanted to stress that shipping a patch with abstraction 
dependencies could even be considered as static linking - because people 
seem to think that static linking enforces the GPL more than dynamic 
linking. (which does say nothing about whether this is true)

but there _are_ non-GPL'ed kernel-modules.
even though they are disliked.

I tried out Pd-0.41-0. Hans tried Pd-extended. Pd-0.41-0 is build by  
Miller. Pd-extended is build by Hans. While it's still on the same  
operation system, it's not the same build system.  I think the  
differentness is in how the GUI and the core of Pd are tied to each  
other.

I still haven't worked out how Miller builds on Mac OS X, i.e. makes  
a so called "app bundle". It's not a matter of just running './ 
configure & make & make install' since the install makefile target  
doesn't make a app bundle. - In fact that operation is nowhere  
mentioned in the Makefile that ships with the src.

I'm not saying this to just cough up shit. But to say that the way Pd- 
extended is build for Mac OS X might be more in the Mac way of doing  
things. That is that running /path/to/some.app/Contents/MacOS/ 
executable might even be the default or standard way of launching an  
application (on Mac OS X). But again i'm no Mac witch.

Okay so hook me up. (That's kinda what I wanted to hear.) I'll get the
source for both. Any hints about where I might start looking?

Is the idea that I'd write a patch?

This may take  _while_.

Re: [PD] Jack OSX 0.75 Intel

[Hans-Christoph Steiner]

You may not have the knowledge to fix Jack now, but you can learn.   
Most of the Pd devs did just that in order to improve Pd.  When I  
started, I'd never touched Tcl and I had taken one class on C eight  
years previous to that and hadn't touched since at all in the time in  
between.  So I basically learned C and Tcl to hack on Pd.

Dynamically linked libraries also trigger the GPL.  For example, most  
Linux kernel modules are dynamically linked into the kernel these  
days, and they definitely required to be GPL.

PD patches are not a clear case like the Cubase example because  
Cubase projects are clearly not programming.  If you consider a Pd  
patch a program, then it means it triggers the share-alike/copyleft  
conditions of the GPL.  When you load a patch, you are forcing all of  
the compiled objects to be dynamically linked in, so the patch is  
definitely linked.

[PD] [PD-announce] Linux Audio Conference 2008: Registration now open

[LAC2008]

Dear all,

The Linux Audio Conference 2008 in Cologne (Feb 28th - Mar 2nd 2008)
is just one month away now. The programme is shaping up, concerts are
being organized and coffee is about to be ordered.

To help us with planning the LAC2008 we kindly ask you to register now
at the conference website. This helps us to estimate how many visitors
we may expect, what individuals the audience is made of, and allows to
produce name tags for all attendees so that it becomes easier to
identify each other.

To register, please use the "Registration" form at
http://lac.linuxaudio.org

Also we now have put accommodation info plus some maps of the
conference location online. You can find these on
http://lac.linuxaudio.org under "Visitor Info". 

Finally if you're living in Cologne or nearby: We are looking for
volunteers who would like to help out in any way, e.g. to host artists
and paper presenters in their flat. If you want to offer your help,
please contact the LAC2008 orga team at [EMAIL PROTECTED] 

The LAC2008 chair is looking forward to have another great conference
with you all.

All the best

Re: [PD] plugin~ problems (ladspa-linux) - strange behavior

[Jerome Tuncer]

Hi glerm,

This has already been discussed a a few times I think. It happened to me 
as well, the workaround I found at the time was to start pd with the 
"unset LANG" prepended i.e. :

$ unset LANG
$ ./pd

Alternatively :

$ unset LANG && ./pd

Does pd started from a terminal throw you an error like this one :

bad screen distance "124,00"
can't find an indexable and selectable item ".x8249400.t827ec80"
can't find an indexable and selectable item ".x8249400.t827ec80"

Re: [PD] High cpu usage

[Javier Garcia]

Hi Hans, 

Here you have the patch..

Im using a core duo 2 2,16 GHz and UbuntuStudio 7.04.

Im
not worried about that high cpu usage, because with the values i said
(1, 2, 3, 4, 5, 6, 8) the movie is played veryveryvery fast, so maybe
is something normal... 

What surprise me, is that the increase of the cpu usage is exponential (or 
similar) around those values.

i cannot believe this.
one of the gpl-faqs at fsf [1] is "If a programming language interpreter 
has a license that is incompatible with the GPL, can I run GPL-covered 
programs on it?"
for me this (the mere existence of this faq with a different answer than 
"programs written in interpreted languages are not covered by the GPL") 
means, that programs running on an interpreter (that is: programs 
written in interpreted languages) _can_ be covered by GPL.

even though it does not mention Pd explicitely (probably because it is 
significantly less used than e.g. Perl), it clearly states that if 
"interpreted libraries" (perl modules, java classes, pd abstractions) 
published under GPL (again: how is this possible if the GPL is not valid 
for interpreted languages) are used, then your program (patch) must be 
"released in a GPL-compatible way".

since when does statically linking defines ownership?
how is the license of supercollider (GPL) different from Pd's license 
(BSD), that it would prevent all of your sc code belong to james mccartney?


apart from that i largely agree.

Hi dafydd

Its true it does work great - on 10.5.1 also. Just have to be aware  
that its only supporting 1 processor at the mo however. (that means  
everything running at the same time as Pd)

Wish I had the know-how to get in there and help out :-/

In this particular case, Hans is wrong and you guys are right, but it's
quite complicated, depending on the type of work which is created and
the license of the software. Let me try to explain (IANAL and I am also
sleep deprived :) ).

Hans wrote: "I think that if you write a patch that uses a Pd library that
is covered by the GPL, technically, your patch is covered by the GPL."

This would only be true if you were:
a) Distributing the GPL library/external with your patch.
b) 'Linking' your patch with the original software.

On count (a) you generally don't distribute externals with your patch -
you expect people to download and install them themselves. Distributing
the patch on it's own is fine even if it used a commercially licensed
external - it's up to other users to procure a license for that
commercially licensed external in order to run your patch. Infact,
if you are not distributing the result, you can do whatever you want
(including linking commercial code or whatever) in the comfort of your
own home and nobody can stop you.

On count (b), I don't think anybody would 'link' a Pd patch with Pd
since that would require the patch to be turned into a data segment and
linked into the Pd binary and a special hook would be required to load the
linked binary segment directly into Pd at runtime instead of reading
it from a .pd text file. In other words, if someone made a stand-alone
application with the Pd file compiled into the binary and then distributed
that, then they would probably be required to adhere to the GPL license
of the externals used (e.g. if they used the linker program to link
the patch into the application). This area is quite fuzzy because some
people even contend whether dynamically linking things is covered by
the GPL - this has probably changed with GPL 3.0 which probably makes
it more explicit (but would still allow an interpereted .pd file no
problems at all). If the developer/distributor used pure Pd then they
wouldn't have to worry about that because it's BSD (except they would
have to flash the Pd license to the user at some point).

It's conceivable that someone would write some software that had
an EULA which specified that works created with that software were
covered by the same license as that software (crossing "levels of
abstraction"). Microsoft's Hotmail service does something like this -
when you create a hotmail account you agree that all data and emails
that pass through their server are owned by them. As for whether this
would stand up in court or not is a different matter. Especially
interesting in this regard is whether code is speech or not because as I
said, the type of work created matters a lot as different works are
considered in different ways under the law.

There is no "magical border". There is just different software with
different licenses and different types of works (which are treated
differently under the law) created with those bits of software. 99% of
the time you are going to be fine and you are going to be able to
license your work in whatever way you want, independently of the
software. When the work is itself a computer program it seems more
complicated but actually really isn't.

Yep. The copyright covers the text of the source code. So if you
re-write the source code in a different language you have created a new
and different text. This is akin to re-writing a novel with different
words and characters and place names, but with the same basic plot. It's
completely legal. In the case of algorithms though, watch out because
under certain jurisdictions they may be covered by software patents
which will bite you in the ass.

The principal difference between and abstraction and an external is that
an external is 'linked' with the Pd binary (dynamically at runtime
usually) whilst an abstraction is interpereted. Interpereted works are
not covered by the GPL, but linked code is.

afaik, licenses do not cross "levels of abstractions".
however, if i have a collection of abstractions published under the GPL, 
then i think i don't cross this magical border.

next comes the question, what is the difference between an abstraction 
and an external non-abstraction object. afaik, GPL does not dissolve 
just because of languages used. (that is: porting of code from one 
language to another is (to my knowledge) not really affected by the GPL 
(e.g.: you can chose the license again) as it usually involves re-coding 
an algorithm rather than re-using pieces of code.; but this is unrelated 
to the language a library is written in)

finally, i am still unsure about the "static linking" clause, and how it 
affects an interpreted language.
i guess, if you have a  patch that depends on a GPL'ed pdlib, and you 
are distributing your patch with this library (e.g. for convencience 
reasons), then you are kind of _statically linking_ and thus your patch 
is automatically GPL'ed too.

but i really don't know
