Re: [PD] Digital outputs, Arduino Mega 2560 & Pduino = problems

[Tyler Leavitt]

If you attach the patch that is in question I would take a look at it. I
never had a problem with my digital outputs on my 2560.

[PD] OT: Web hosting solution for running PD

[Tyler Leavitt]

Hello list,

I write a lot of generative sound art, and for the ones I would like to
include on my online "resume" I would prefer to have streaming audio of
patches actively running rather than recorded audio. I know, it's
nit-picky, but putting a pre-recorded audio clip of a generative patch
seems dirty to me. I currently host my page from my comp (and I can do this
just fine) but I'm going to be putting it in someone else's hands for the
reliability factor.

Has anyone here had experience getting a web hosting company to allow you
to run an instance of Pd on their servers? What solutions are available to
me?

Thanks,
Tyler

Re: [PD] Stream phone call to pd?

[Tyler Leavitt]

I think the cleanest way would be to write an app that saves audio
conversations to a server, and then you can manipulate that saved audio
anyway you like from PD. I found a bunch of apps that save conversations on
SD card, but could not find any (in the limited searching I did) that have
the potion of saving the data on a web location.

[PD] [OT] Know of any live data streams (audio/video/img/txt)?

[Tyler Leavitt]

Hello list,

I'm looking to get my hands on some data to turn into sound. I was thinking
web cams, streaming audio (harder to find ambient/landscapes, I know
there's lots of radios [speech and music]), weather information, etc.
Anything that is updated/streamed fairly consistently, perhaps by the
minute would be the minimum I'm looking for. I can find traffic cams pretty
easily... whatever you think would be interesting/hard to find. I'll share
some of the stuff I find if this seems to pique interest.

Thanks,
Tyler

Re: [PD] 2009-2010 Macbook Pro 2.2GHz Latency?

[Tyler Leavitt]

10ms is around the human-ear latency, so anything at that level or below
should be good enough for guitar/drumming (this is anectodtal... Iḿ not
sure the exact science behind it). Ive never had a problem with my friends
older 13" MacBook Pro used as a guitar FX box.

[PD] Mouse data without Xorg boundaries

[Tyler Leavitt]

Hello list,

Not sure if the title explains it concisely enough, but I'm looking to get
mouse data without the screen limits of X. So basically when I drag the
mouse to the far-right boundary of the screen and continue dragging, though
my pointer stays the same on the screen, obviously there is still data
being sent from the optical mouse to the comp that states I am moving
right. How can I get this data? I'm mounting an optical mouse upside down
under a wheel and I want to read that data. I thought MouseState from
cyclone libs would give me this with the "delta" x and y, but those are
confined to Xorg's limits as well. Any ideas? I don't feel confident in
hacking mouse drivers without guidance

Perfect. Thank you guys. I haven't tried it yet but I'm sure this is
exactly what I need, as closing the actual patch is irrelevant as long as I

[PD] Switching Between Multiple Patches for Installation

[Tyler Leavitt]

Hello all,

So I have around 8 generative patches/static compositions that I want
to present as an installation. Less conceptual, more demonstrative of
Pd. So about every 2 minutes I want a fullscreen window of one patch
to close and the next patch to open fullscreen so that people can see
the inner workings (I plan to do visuals through GEM and a projector).
When I say fullscreen I mean fullscreen of the laptop, with the GEM
visuals proceeding as usual. I understand how to accomplish the
switching of the audio, but to get the patches themselves to take
focus I'm afraid I'll need to write a script in Tcl/tkl, which I have
no experience in. Does anyone have suggestions, or code from a similar
presentation they could share?

Thanks,
Tyler

It'll still be on the forums. I figured once we get some ideas in it'll be

account can PM me for it.

So the rules are loose at this point (especially since we haven't made any
=). Until I can get a working version of a bot to do this we can just do
this manually. Once we get a variety of options in the account I'll randomly
pick one and post it for the first challenge.

Re: [PD] Patch Contest Thread/List

[Tyler Leavitt]

Cool. Yeah, I don't think the app needs to do anything to grand... just take
submissions and then randomly select one once a month and auto-post on the
forum and list. I'll try and start a quick and dirty one tonight after
homework is done =)

Any suggestions on what to call this? It's not a huge deal but mmb made a
good point that "contest" isn't really applicable... he suggested
"challenge" which sounds good to me. How should we format the subject line
for the list notification email?... would [PatchChallenge] be a suitable
identifier?

Nope =). Do you have any links to tutorials or demos of what can be done
with it? I couldn't quite put together exactly what it is from the site (

Yeah I would be fine acting as a moderator (for the forum). Andy Farraday
mentioned writing an app that would take theme submissions... I don't know
how easily this could be integrated into the forum but we'll discuss that
more. It appears "Maelstrom" is the main moderator of the forums, so I'll
contact him and see about getting it setup.

I think you are misunderstanding Soares' reponse Tad. When you hit the
"reply to all" in Gmail it puts the last user's e-mail in the "To:" box,
which was you. I don't think he was trying to insult you at all, or even
direct that comment at you

Maybe I'm wrong,

Re: [PD] Patch Contest Thread/List

[Tyler Leavitt]

It was mentioned that it might be best to do this on the forums, with an
additional notification sent to the list... perhaps in the main "contest"
forum there could be a link to your web app titled "Submit Contest Idea"
where users can submit ideas. The web app could also be in charge of then
auto-posting (randomly or otherwise) a new contest thread monthly. Any
thoughts?

Yeah, the compressed/chip patch thread was what prompted me to bring it
up... would it be too spam-like to post new themes to the pd-list as well
once the thread is created on the forum? I personally check the lists at

[PD] Patch Contest Thread/List

[Tyler Leavitt]

Hello list,

I'd always thought it'd be fun if there was a patch contest similar to the
Fark Photoshop contest threads. Is there already something similar happening
in the Pd community? If not, how easily could this be integrated (if there
is enough interest) and how? Maybe it could be a sublist, like [ot] or
[pd-announce]... or just a specific tag in the subject line. It wouldn't
have to include the voting aspect that Fark has and it could change
theme/concept once a week. Is there any interest in this?

[PD] Controlling a Printer

[Tyler Leavitt]

Hello list,

I was curious if anybody has dabbled in controlling a printer through pd.
I'm waiting for a cheap one to arrive at the local second-hand store, so
while I wait to attempt it myself I thought I'd ask the list. Specifically,
I seek to control the location of the printer needle(?) that moves
horizontally. I figured I could attach a slide to it and run a guitar string
under it for some techno-slide music.

Any input appreciated,
Tyler

Re: [PD] Pd "monosymphonia"

[Tyler Leavitt]

I have been working on a generative patch of my own and have been
contemplating different methods of exhibiting it myself. In my school's art
department (of which I am majoring in) there is not much awareness of
computer/sound art, and I was thinking if I could get some other works to
display I could put together a sort of exhibit of Puredata/generative
patching...

I'm not sure how it would look, but I was considering something as simple as
a wall of 4 or 5 headphones on a hook that people could walk up to and
listen to at their leisure (kind of a play on the traditional method of
display for paintings). Maybe a little placard next to it with a blurb by
the artist about their methods/conceptions behind the work. I don't know...
I was going to further contemplate it before I asked the board, but since
you've brought it up...

Any other suggestions on how to exhibit generative patching?

Re: [PD] Pd performance at TED

[Tyler Leavitt]

I think a lot of the folks who are disappointed with this being at TED are
frustrated because they are looking at it from an academic standpoint or at
least looking at it as a non-performer. You have to remember that he is
performing, and on top of that, probably trying to make a living as a
performer. For christ's sake his name is Onyx Ashanti and he made a new name
for his music, "beatjazz" =). It's a little over-the-top and mediocre if you
are expecting some ground-breaking, concept piece or a technical
demonstration of the capabilities of Puredata... but it's not. This guy is
an entertainer who is probably combining his love of electronics with his
love of music... I don't see anything wrong with that.

Plus... isn't this just an audition?

Heh... wow. Thanks for pointing out my negligence and all the help up to
this point =)

Re: [PD] Graph a circle arc in an array?

[Tyler Leavitt]

Using the sqrt(r^2-x^2) formula I get the same results as with the [sin],
[cos]. Maybe I'm just implementing it wrong, but I can't figure out why it's
not plotting the correct y values...

Here's the patch I sent before with my implementation of the sqrt(r^2 - x^2)

Re: [PD] Graph a circle arc in an array?

[Tyler Leavitt]

I've not had any real success using the formulas with [sin] and [cos]...
maybe I'm missing something here. The only solution that I've gotten to work
is the midpoint circle algorithm with Peter's patch.

I've included a patch to show where I'm struggling... When the arc gets
drawn with bigger radiuses (and bigger arrays) there are a lot of indexes
with no value so it's constantly jumping between 0 and the correct value. Is
there a way to get pd to approximate the values in between (more or less an
average between plotted points)?

Thanks so far for all the help
Tyler

[PD] Graph a circle arc in an array?

[Tyler Leavitt]

Hello all,

I am trying to graph a section of a circle into an array. I have been trying
to wrap my head around [sin] and [cos] but none of my configurations get
results. If you had a circle with radius 100 with a center at (0, 0) I'm
trying to get the upper right quadrant (positive x and positive y). The
start point being (100,0) and the end point being (0,100).

Any ideas on moving forward?

Re: [PD] creating an engaging interactive art in public space

[Tyler Leavitt]

Even something as simple as an indicator light that is motion triggered is
enough to communicate the interactivity of the piece to the audience...
there are more creative ways of course.

[PD] [ngrid]?

[Tyler Leavitt]

Hello all,

So I posed a question about calculating triangles made by intersecting lines
is a pentagon (thanks for the help Mathieu), and now that it is done I want
to easily control the 5 vertices. I remember using [ngrid] at some point,
which is [grid] but with multiple vertices... exactly what I need. Googling
turned up this:
http://puredata.hurleur.com/sujet-1378-designing-surround-sound-mixer which
basically says [ngrid] is in the ix library. Well I can't find any mention
of ix library anywhere...

Does anyone know of this library/[ngrid]? I just installed extended 0.42.5
fresh thinking it would be in there...but nothing.

[PD] Calculating Triangles Inside A Polygon

[Tyler Leavitt]

Hello all,

I have an idea for an object that controls parameters based off of the area
of triangles inside a polygon (I was thinking volume of different harmonics
for a synth, but it could be anything). I don't even know if this
is mathematically possible, and I've done enough Googling to where I'm
beginning to think that it is not. But perhaps I just don't know how to
correctly phrase what I'm searching for...

Can anyone shed some light on this? The idea is to drag the vertices of the
polygon to change the shape, and consequentially the masses of triangles
inside. I've attached a PNG of what I'm trying to describe as far as the
triangles made by intersecting lines. If you know what I'm going for but
don't want to explain it to me, perhaps you could point me in a direction,
or give me the correct term to describe this. I'm still willing to continue
devoting lots of time to Googling/research =)

Tyler

(And in this example with the pentagon there would be 10 different
triangles... didn't mean to label the pentagon).

Re: [PD] Need Help Understanding pack

[Tyler Leavitt]

This may be getting too off topic, but just today in class our prof wrote
the variable "b" as "d" and then upon realizing his mistake corrected it and
said "the other b". Not sure if this is dyslexia or right/left related (or
if the two are very similar).

Re: [PD] hardware implementation of [*~]

Thanks everybody for the replies, exactly what I was looking for. I am so
new to this field of music/electronics that I frequently find myself
struggling to grasp fundamental concepts. Googling "mc1496 ring mod" gave me
plenty of circuits to look at, as I'm sure the couple of links you gave me
Ed will too.

Thanks a bunch.

[PD] hardware implementation of [*~]

[Tyler Leavitt]

Hello all,

So I'm getting my feet wet in digital circuitry this quarter at my
university and I've got numerous projects I want to waste my time on, one of
them being a simple ring mod effect in the same vein as the ring mod found
here: http://en.flossmanuals.net/PureData/AmplitudeModulation

My question is what would be the hardware equivalent of the [*~] object. I
guess it don't have to be digital... even an analog equivalent would help me
understand it better.

Hope this question makes sense, I don't have a good grasp on the terminology
in this field one bit.

Re: [PD] how can I clear [vd~]

Hello,

Thank you for writing that up Mathieu, I was looking for that exact fix
about 3 months ago. Could you or anybody else that wants to take up the

assuming it would need to be recompiled, and I've never recompiled a single
library or object.

Or even point me to a existing tutorial? =)

[PD] SBLive! and surround sound

[Tyler Leavitt]

Hello all,

Has anyone had luck setting up more than 2 channels output with a SBLive!
Value card in pd? I am trying to get surround sound going and have thus far
only been able to use 2 output channels with any success (using ALSA-- no
luck with JACK either).

# lspci :
02:08.0 Multimedia audio controller: Creative Labs SB Live! EMU10k1 (rev 08)

I figure maybe something in .asoundrc could fix it but am having no luck...
any help appreciated!

[PD] [route] object confusion

[Tyler Leavitt]

hello all,

this should be a basic question for probably the majority of you, but i'm a
n00b so here goes.

i'm working with the [plugin~] object and want to use a [popup] object to
make it more manageable. so my idea was pretty elementary

[listplugins(  [plugin~]---[route label]-[append
$1(--[popup]

my error is "$1: argument number out of range" so i'm pretty sure it is
expecting a float and getting a symbol. i'm sure this is a pretty basic p:d
concept but i can't grasp how to send a message with a variable symbol
coming in, if that makes sense. i need to be sending [append PhaserII( or
something similar. when i [print] the [route label] i get the PhaserII, but
it's not passing that along in the append message.

i hope you can help, if my explanation was not too confusing =)

thanks

[PD] Digital Delay Patch

[Tyler Leavitt]

Hello all,

Forgive me if it is a crime to just outright ask for a patch... but I've
been trying to make a digital delay stombox emulator with delwrite~ and
delread~ to no avail. I've searched and apparently I want to use the vd~
object, however, I am a total n00b when it comes to digital audio and can;t
understand half of the terminology in the patch help box.

If someone has a patch I could dissect, I would be forever grateful. I'm
looking to make a digital delay with feedback and delay time knobs. Any help
at all would be great, but a working example I could inspect would be
awesome.

Thanks much,

[PD] [hid] button down press

[Tyler Leavitt]

hello all...

first off, wow! i never took a look at pd before i needed to control
hydrogen via usb gamepad today, but wow... awesome program, sorry to have
looked over it for so long. that being said, many thanks to the community &
developers for making my computer audio tinkering 10x more fun!

now... i just started using it today. my current flow for sending MIDI
events via USB gamepad button downpresses is like this:

[hid]---[route key][route btn_0][route 1][makenote]

the second route object of course has more than one button (btn_0 through
btn_11) with each output going through its own [route 1] (to only signal on
the down press). needless to sat thats a lot of [route 1] objects... is
there a way i can clean this code up? something along the lines of [route
btn_0,1 btn_1,1 btn_2,1] etc

hope i made myself clear...

thanks much,
