suppose you have two subpatches both heavily taxing the cpu with
audio-rate signal processing, but due to your switch, you only want one of
them on at once. is there a way to selectively disable dsp on a subpatch
basis? i saw something in the help files about a similar trick for
blocksize, but perhaps i havent dug deep enough to into the scheduler code
or help files to know if something like a simple toggle .x40203 DSP 0 method
exists..

hi,
exactly for that purpose, but for different kind of data,
you can find :

for audio signals :

spigot~ from http://ydegoyon.free.fr/software.html

for pdp video processing :

pdp_spigot from http://ydegoyon.free.fr/pidip.html
for other data, like messages or floats,
the built-in spigot, demux or moses
can do the trick.
cheers,

hi,
I would stick process 1 in one subpatch, process 2 in a second
subpatch, and
control them by sending 1's and 0's to switch~ objects inside each
subpath,
turning them on or off. This just turns dsp on/off for that subpatch.
i do think, that "signal flow" was *not* referring to pd's signals but
rather to messages (considering the terms "Gem" and "video processing"
in the original mail)
but of course [switch~] this is perfect for this kind of things.
[moses] just works on streams of floats, so it is not really useful
for unspecified "messages"

nice. using the built in [==] makes a lot more sense than the [invert]
object i was using...

for this, try [switch~], which serves the function of "switch"ing on and
off DSP for a subpatch. send it a toggle.
somewhere i remember seeing an abstraction which would detect when the
inlet~ level is quiet and [switch~] off DSP at that time, and turn it on
again when it gets more level ... i thought it was a good idea, as long
as there's some envelope to avoid clicks. can't find the abstraction now
though...

The [threshold~] object is your friend here.
I use this technique quite a bit for things like volume envelopes and
filters.

I will have to take a look at this patch. What are the advantages of
using [sigzero~] (which I am guessing bangs the output when the signal
gets to zero) over something like [threshold~] which gives you control
over low value bang and high value bang, along with jitter control?

Subject: [PD] py/pyext and dyn~
Dear Thomas,
Being a great fan of py/pyext, I recently tried to use dyn~ in
combination.
...
It turned out that I did not read carefully your webpages...
I received a "Fatal Python error: PyThreadState_Get: no current thread" as
a response :-/
But just to be really sure, is it so that dyn~ does only accept the
dynamic
...
creation of standard Pd objects
and not the one of complex objets like the ones created with py/pyext?
If yes, do you see any chances in the futur that this might happen?
In fact I would really like to use py/pyext to drive dyn~ to build pd
objects containing py/pyext objects...
cordially,
vincent

A hexdump would be a way to see the actual bytes, but I think you would
want

to see sample frame values. That would mean reading the header of the WAV
file and based on the number of channels and the sample type printing a
listing of human readable decimal numbers.
One way to do this in pd, is to write the sound to a table with soundfiler
I

think, and then reading the table and printing it out to the console or
putting it in a textfile object and saving that.  The table has to be big
enough, but if you really want to see the sample values, you are probably

Subject: [PD] loading libraries in OS X?
Hello Everyone
I am in the process of switching computers, and operating systems, from
windows 98 to mac OS X, and I am trying to load all of my patches that I
wrote in windows to my new computer.
I had no trouble installing pd on OS X, but now I can't figure out how to
load libraries (percolate, especially!) on to Pd. I know how to do it on
the DOS command line.
Is the syntax the same? i.e.:
pd -lib percolate ........or whatever...
It seems like I am missing a pretty simple solution, though I would like
to have Pd for OS X running as soon as possible, so any help would be
greatly appreciated.
Thanks!
David

To run pd from the terminal I am using the command "open pd", but when I

I think my problem has a lot to do with my lack of familiarity with the
unix syntax. Right now I can run pd from the terminal using the command
"open pd", but when I add the tags to add libraries, the shell looks for
them as if the tags were file names.
where is the .pdrc?
do I need to change the settings on the terminal?

have the .pdrc or at least an alias (on your .tcshrc file)
