Re: [PD] $0 and Data Structure Templates

[Mike McGonagle]

Luke,

I think this should be allowed, hell, even the use of other $
arguments. It would be nice to be able to allow abstractions to create
their own private data structures, or at least ones that could be
named based on a creation argument.

If nothing else, it would prevent any kind of structure naming clashes
between objects that define structure with the same name.

I had, like you, tried this same thing only to find that the saves
files were then having those structures renamed.

It would also be nice if you could store a reference to any type of
data structure within one of these "private" data structures... of
course, the abstraction being passed this arbitrary pointer to a data
structure wouldn't know what to do with it, but it could be sent out
an outlet to some outside processing code. Could this be done by
adding a 'pointer' type to the structure definition? Something like:

[struct my-struct float value pointer object]

Re: [PD] Multi-slider attempt

[hard off]

i understand your question, and unfortunately don't have the answer because
datastructs are a bit foreign to me.

however...if you are going to use this structure for controlling audio or
visual processes, then won't you need to constantly poll the y-values of the
handles anyway?

[PD] $0 and Data Structure Templates

[Luke Iannini]

Hallo all,

I'm working on my complex DS sequencer, and the time has come that I'd
like to read and write sequences from it.

The problem is this: all of my templates are written like [pd
$0.note-template] to allow multiple instances of the sequencer, but
this seems to be incompatible with reading and writing data from a
subpatch ( like [write my-data.structure( - [pd $0.data] ), because
the $0 is expanded in the written file (so it's full of "template
90953loopMarkerTemplate;" etc. rather than "template
\$0loopMarkerTemplate;").

The immediate thought was to split the templates into a separate patch
altogether, and spawn it before creating the sequencer or use a
singleton approach.  But, this ruins using [change( messages from
[struct]s as well as selectively turning on and off [draw*]n elements
on a per-sequencer basis.

The only other option AFAICT is to forget DS reading and writing and
just mirror the data in lists with SSSAD, but that would be a shame
considering the capability exists already.

It seems to me that the written datastructure definition should
preserve $0, no?  Anyone have any other ideas?

(apologies if this is unclear, I'm very tired at the moment)

We wanted to do mp3 streaming vs. ogg/vorbis to keep this as mainstream 
as possible. Shoutcast was the one we knew must work so we started with 
that and never left. It would be nice to switch to Icecast due to FLOSS 
if it works as well, but we are pretty committed to mp3 as it is so 
universally accepted.

We use the GUIs for everything. Pd is only doing mp3cast. But it is all 
automated. We have a remote broadcast machine too whose interface and 
operation is all Pd/GRiPD and also it uses mp3cast~ to stream to the 
main console.

yep. It's not that we are a fan of flash but we want to be as inclusive 
as possible, not just a station for geeks. We found that flash was the 
lowest common denominator for a web player. Even Java, which we started 
with, wasn't on as many machines as flash.  We do a lot of broadcasts 
which students' grandparents etc. tune into and they could deal with the 
flash player better even than iTunes or winamp.

If there is interest in continuing specifically about radio and 
streaming, we might need to move off the Pd list? Email me directly.

Re: [PD] Peak envelope follower?

[snapshot~]

IIRC gives you the value of the first sample in the last block when banged.
It's more useful than [env~] for 'instantaneous' measurement but sorely
lacking for practical use - for instance the first sample may be atypical
and the remaining 63 (by default) completely different. Obvious, and probably
trivial, improvements to [snapshot~] would be an index argument a la [dirac~]
that lets you set the sample to read, an option to return a list, or the
largest value.

Re: [PD] [GEM] error in creating gemwin in fc8

For some reason my computer stopped using the nvidia driver and that was
causing the problem, so I used that driver again and it all seems to work
now.
although in theory it should still run without the nvidia card right?
In any case, I needed to solve this problem fast to work on some video

[PD] Chicago Patching Circle (Sunday, December 14th)

[Mike McGonagle]

Hello all,

Just a reminder about the patching session. Basically, we are on for
Sunday, December 14th, at 5pm. The location is:

Red Line Tap
7006 N Glenwood
Chicago, IL

If you are going via the EL, go to the Morse Stop, and exit to the
north end of the platform. From there, go northwest on Glenwood, the
Red Line Tap is the first door from the corner.

If you are driving, there is a parking lot to the north, 2 block. It
is a shared lot with the Trilogy center, at Estes and Glenwood. If you
need a map, you can try google maps.

If everyone who is interested in showing the work they have in
progress could email me, I would like to put together a small list of
all the participants.

Thanks,
Mike

Is it possible to retrieve the name of the parent patch?  If so, then
mabey I can rework 
rc-sssad to use the parent patchname and prepend that to the keys
automatically so that
it will yield the same results, but without having to manually add a

Before I begin, I'm sure this has all been done before but I'm not aware
of it so I'll re-reinvent the wheel.  Besides, you know how the wheel
works when you build it.

Ahh I see, I think I'm using the wrong terminology then.  I'm using
"local" as in objects with a certain osc-style prefix.  I'm using sssad
to save state values within reusable abstractions and there may be a
number of them on one song patch.  The sssad keys are set using the
objects assigned name which is $1, so 

[rc-delay~ p] has keys [sssad p/delay], [sssad p/feedback], etc...

Let's say SongA has a delay and 2 oscillators of some kind and SongB has
another delay and 2 drum samples.  The way I had it before, I could not
work on SongA and SongB at the same time because if I saved one, it
would also have the values of the second.  Now I add a prefix to each
object's name in SongA, say [rc-delay~ /songa/p] and the same with Song
B [rc-delay~ /songb/p].  then I just check for each prefix using
[rc-sssad /songa] in SongA.pd and [rc-sssad /songb] in SongB.pd, and
saving one will only save it's objects.

... anyway, thanks for sssad, it makes using my abstractions s much
easier since I can just create, fiddle, and save.

Are you using the latest version of sssad? Because new versions have
local saving already built in - you activate it by giving the
sssad-instances an additional argument, usually $0, like this: 

 [sssad somename $0]

Re: [PD] Pd as a 24/7 Icecast/Shoutcast source client (alternative)

[Ilias Anagnostopoulos]

John,

I had a look at the radio pages. Looks good. Is there any particular 
reason you chose Shoutcast over Icecast? Are you using PD solely for the 
mp3cast~? Or is it doing more than that? Are you using the GUI's for all 
of these (jack, PD, jack-rack, xmms)?

 From what I understand, ffserver is used for the flash version, right? 
I haven't really heard much about flash stuff, I personally dislike 
flash and I don't even have in installed.

Re: [PD] [GEM] error in creating gemwin in fc8

well, it seems like your Xserver is missing the GLX (openGL for X) 
extensions. since Gem highly depends on openGL, it refuses to continue...

which driver are you using? probably your Xorg.conf needs tweaking.

do other openGL apps work? a good start is glxgears (if this doesn't 
work, chances are minimal to non-existant that Gem will...)

if glxgears do work, try setting the environmental variable 
GEM_SINGLE_CONTEXT to 1. (setting this variable can be considered the 
first voodoo to do when problems occur)
