I didn't have any specific ideas in mind when I was working on getting
libpd running on the BUG. I started working on it when I started with
the company, as a way to gain some understanding of OSGi and jni
bindings. I thought it might be useful to experiment with ideas like
graphical event-driven programming and WYSIWYG GUI design, and I
thought libpd might be a good way to get those things up and running
quickly. I've also been interested in prototyping digital instrument
design, and having a small programmable DSP platform with easy access
to an accelerometer, camera, and analog and digital IO seemed like a
useful tool.

errordeveloper, I agree, the price point doesn't work for everybody.
To be clear, I wasn't trying to sell units, I just wanted to share
something that I had done. We've tossed around the idea of a high-end
audio module. I'll pass that information along if we end up doing it.

[PD] libpd and BUG Labs

[Andrew Turley]

I work for BUG Labs. In my spare time I've been playing around with
some ideas for using libpd on our device. I put up a blog post about
my work here:
http://community.buglabs.net/aturley/posts/240-libpd-Embedding-Graphical-Programming

Nothing revolutionary, but I thought people might enjoy seeing Pure
Data on yet another platform (in this case, running in OSGi on ARM).

Re: [PD] Pd - DSP in a web app

[Andrew Turley]

Those are both good reads. The "Web Audio! All Aboard" article is
pretty inspiring.

As for running Pd on a server, if the user's don't need to share data
(for example, if you are streaming the results of their patches back
to them) you could run one instance of Pd per user. That way one user
couldn't kill audio for everyone.

In most of the work I've done the web UI interacts with Pd patches,
but it doesn't actually send patches, so to the extent that I trust my
own patching ability, I can feel fairly certain that my instance of Pd
won't crash. I guess I assumed that with the sequencer that's the type
of thing you would be doing.

Re: [PD] Pd - DSP in a web app

[Andrew Turley]

A few people (myself included) have built web UIs that control PD
patches that run on a server. The technique I've used involves an http
server that acts as a gateway, transforming http requests into OSC
messages which are then sent to PD patches. My blog has some info
about some of my experiments:
http://www.pillowsopher.com/blog/

I've also been looking at wrapping libpd
(http://gitorious.org/pdlib/pages/Libpd) in a web server (maybe
writing a node.js binding?) and using that to generate audio based on
data from a web browser.

You can check out [Phasor~] over at Noisebridge. It's a group for

They meet "irregularly".

You might also check out the Bay Area Computer Music Technology Group
(BArCMuT) for some like-minded individuals.

Re: [PD] any mac OS terminal experts?

[Andrew Turley]

So first off, you don't need to call them with 'open' from the command
line. You can just run them directly like any other command, like
this:
  echo "a b c 1 2 3;" |
/Applications/Pd-extended.app/Contents/Resources/bin/pdsend 3939
The command reads the standard input and sends the data to PD.

Assuming you have a PD patch running with a netrecieve object
listening to port 3939, you can send the same message as above with
this Ruby code:

  require 'socket'
  hostname = "localhost"
  port = 3939
  s = TCPSocket.open(hostname, port)
  # don't forget the semicolon!
  s.puts("a b c 1 2 3;")
  s.close()

Re: [PD] any mac OS terminal experts?

[Andrew Turley]

You should be able to run them from the command line. When you say
that you are "opening the files", do you mean you're clicking on them
in the Finder? As you've said, that will just open up a terminal
window.

Also, these commands just communicate with strings over a TCP socket.
If you're comfortable with socket programming in Ruby then you don't
even have to use pdsend and pdreceive.

Re: [PD] iPhone control

[Andrew Turley]

I've used the various OSC controllers (MRMR, OSCemote, TouchOSC) and
I've written some custom web apps to control things (I have some posts
over at www.pillowsopher.com/blog). The OSC stuff is faster (more
responsive and less latency) than the web stuff, but I liked the
degree of control the web apps gave me. OSCemote is a nice compromise
because you can create a UI using HTML and JavaScript.

Re: [PD] making scales from frequency values

[Andrew Turley]

The ratios are maintained because you're multiplying (I'm not quite
sure what you mean by "even out"). But yes, you could also convert to
MIDI and then use addition, and then convert back to set the
oscillator. Six of one, half-a-dozen of the other.

Re: [PD] making scales from frequency values

[Andrew Turley]

Just FYI, looking at BT2,BT3 and BT4 I see that the ratios of the
first partials is pretty close to a major second. Also, the ratio of
the first and second partials is just about 2.64 for each of the tones
you have given, which works out to something like 1 octave + a 4th
(between the major and diatonic).

The attached patch lets you set the first partial frequency (either
specifying the exact frequency or using the slider to select a MIDI
note), then sets the remaining partials as a ratio of the first
partial. I calculated the ratios using the ratios from BT2.  This
should give you an idea of how to maintain the spacing of the
partials. You can then use a chart like the one Derek included to
figure out which frequencies to use for the first partials, or you
could play around and find them by hand.

Does that help at all?

[PD] TUIO iPhone web app and web server

[Andrew Turley]

I put together a little iPhone web app and a Python web server that
let you send TUIO messages using Safari. The web app sends multitouch
information to the web server, which takes care of translating them
into TUIO messages. I thought maybe some people on this list might be
interested in it.

Here's a blog post that talks a little bit about my motivations:

The easiest way that I know of is to set up an IAC loopback device

Re: [PD] XBOX 360 controller to pd (noob question)

[Andrew Turley]

Have you installed drivers for the controller? You might want to start here.

http://tattiebogle.net/index.php/ProjectRoot/Xbox360Controller

I've used his PS3 driver. It only seems to work with USB, not over
Bluetooth. I don't know if the XBox driver supports Bluetooth
connectivity or not. Once you have the controller hooked up you should
be able to use the [hid] object to get the inputs.

Re: [PD] max for live

I think the nicest thing about the Live/Max integration is that you

Re: [PD] osc on winXP

[Andrew Turley]

[dumpOSC] seems to require a port argument, otherwise it will not be
created correctly. Thus, you need:

[dumpOSC 9393]

rather than just:

[dumpOSC]

Also, if you try to create a second instance of [dumpOSC] with the
same port as an existing instance, the new instance will not be
created.

I hope that helps.

I'm working on an application where I want to take a snapshot of the

The part I'm having trouble with is getting the output from [fft~]. In
the help file for [fft~] they use [print~] to print out the vector
coming from the [fft~] object.

I think I know how to manipulate the list once I have it, so that part
isn't a problem. I just want something that I can [bang( every once in

There's [pdp_mgrid], which will divide the camera's field into a grid

[PD] pasted objects now end up under the original object

[Andrew Turley]

I'm running Pd-extended 0.40.3 on an iBook G4 in OS X 10.4.11, and
I've noticed that if I copy an object and then paste it to the same
place, the newly pasted object ends up under the old object. This is
annoying because if I have some objects that are already connected to
other objects and I copy and paste them, I then have to move the
original objects out of the way to get access to the newly pasted
objects. I feel like in the previous version of Pd-extended the newly
pasted objects end up on top of the old objects, so that you could
just paste and them move them out of the way.

So first, is my memory of the old behavior correct? Second, is this
the behavior people would expect? Third, are people seeing this across
platforms, or is it just me?

Re: [PD] Newbie request

[Andrew Turley]

The [fiddle~] and [bonk~] objects should let you capture all of the
information that you are looking for. As far as getting that
information from Pd to Liquid Media, that may be the tricky part. Your
current pedals are sending keystrokes straight to Liquid Media. Do you
know if there is a way to control Liquid Media via MIDI messages, or
some sort of message sent via a socket connection (maybe OSC)? If so,
then you might be able to use Pd to capture your pedal input and then
combine that with the information from [fiddle~] and/or [bonk~] to
send the appropriate information to Liquid Media. If the only way to
control Liquid Media is through keystrokes, then you might need to
write some software that intercepts the keystrokes from the pedals and
changes them depending on what is going on in Pd.

[PD] sending applescript events

[Andrew Turley]

Has anyone done any work getting Pd to send applescript events? I know
I can use [shell] and osascript, but then I incur the cost of starting
a new program. I've been playing around with appscript in Python, but
I haven't had much luck getting the Python extension to Pd working, so
that's out for now. So has anyone tried anything else?

Re: [PD] reading suggestions for wii/sensor data conversion

[Andrew Turley]

>From what I understand about pmpd, it looks like you can send an force
message to a mass object. As Claude says, F=m*a, so you can calculate
the force to send to the object based on the object's mass and the
acceleration data coming from the Wiimote.

You will probably have to scale the signals coming from the Wiimote to
use in your application. For example, if the acceleration on one axis
is 542, you will have to decide what you want that to mean in your
model.

Also remember that gravity causes acceleration, so even if you aren't
moving the Wiimote you will still detect accelertion. You may want to
try to remove that from your calculations.

I'm not sure if any of this is helping. I've been playing around with
accelerometers a little bit lately, so I might be able to help you,
but I'm still not sure I fully understand what you're trying to do and
where you're running into trouble.

Re: [PD] looking for a way to execute a program from pd

[Andrew Turley]

Wow, thanks. I didn't know about pdsend and pdreceive, I had always
just written my own network handling scripts and/or used netcat. Since
I don't need pd to deal with any of the program output this may be a
good avenue to explore.

[PD] Fwd: Wii remote controller and Mac OS X

Hrmm ... well I just hooked up my regular SIXAXIS controller (not the
 GH controller), and I'm not getting the XYZ data either. Sorry about
 that, I assumed it would work the same way.

 And the GH controller is USB, not bluetooth. It is wireless, but they
 use their own communication protocol, not bluetooth. I'm not sure why
 they did that. My only guess is that it saved battery life, or shaved
 $0.50 off the price of the controller.

[PD] looking for a way to execute a program from pd

[Andrew Turley]

Hey, I was wondering if there was a way to execute a program from pd.
Specifically, I would like to use the osascript command in Mac OS X to
send a command to iTunes.

I can write an external to do this, but if there is already something
out there to do then then I will use that.

Re: [PD] Wii remote controller and Mac OS X

[Andrew Turley]

Oops, I should be a little more specific ... what I described was my
experience with the Guitar Hero controller, which as far as I can tell
is just a repackaged SIXAXIS controller that sends a different device
ID. It may be slightly different for the regular SIXAXIS controllers,
but use [print] and see what you get.

Re: [PD] Wii remote controller and Mac OS X

[Andrew Turley]

I hooked up a [print] to the [hid] object's first outlet. If you do
that you should see a constant stream of messages that look like this:
...
0x002c 561
0x002d 593
0x002e 512
...

0x002c, 0x002d and 0x002e identify the X, Y and Z messages, and the
numbers after them are the values. I was expecting them to show up as
regular gamepad messages, so I actually didn't know that I was getting
them at first.

Re: [PD] Wii remote controller and Mac OS X

[Andrew Turley]

For the record, the SIXAXIS controller works well in Mac OS X with this driver:

http://tattiebogle.net/index.php/ProjectRoot/Ps3Controller

I've used that for the Guitar Hero controller. Using the [hid] object
I get 3 continuous values from the XYZ sensors.

Re: [PD] HID: Am I doing this right?

[Andrew Turley]

I don't know exactly what you're trying to do, but it might just be
easier to use [key], [keyup] and [keyname].

But if you do want to use [hid], once you have the device open you
have to send a [1( to start polling. You might want to just hook a
[print] object to the output to see what kind of info is coming out,
and then [route] the messages accordingly.
