Hello,
I'm working on a project of simulating 3 dimensional manifolds different from the Euclidian space and I need to find a way of rendering thousands of sound sources in real time.

All the sources will emit the same sound, but anyway, rendering with normal spatialization patches is impossible, I imagine.

Any ideas on how to do it?

Thanks!

Hello,
I've been using a Mac Mini running pd-extended and two arduino boards attached to it to control some electric motors of an installation. I use Pduino and the StandardFirmata uploaded into arduino and I had no problems until I decided to do a file transfer from my MacBook into this Mac Mini using Bluetooth. I opened the Setup Bluetooth Device, I chose to open a connection to my computer and did the file transfer.

Unfortunatelly, when I opened the patch I've been working for several months, one of the two arduino boards was not working. The comand

[open 2<
|
[arduino]

started to cause an error message saying the port I was using was no longer of my arduino but the tty.Bluetooth port related to my MacBook. I turned off the Bluetooth Devices of both computer but the tty port related to that bluetooth transfer is still in "the place of" my arduino usb tty port.

Then I tryed all the possibilities: [open 0<, [open 1< and [open 4< to try to find the right tty port. The [open 3< is already in use by the other arduino board which fortunatelly is still working. When i tryed [open 5< I received the message that I could only use more than four ports on .

Do anyone no how to manage these tty ports? Can I erase the tty port related to the bluetooth transfer? Will that cause my arduino tty port to come back to the list in which pure data can access?

I'm a bit scared because the installation will be exposed in two weeks!

Thank you very much for your attention.

Hi.

Im trying to compile the Pd-0.40-2 on a PowerPC G4 running OS X and i get this error:

gcc: installation problem, cannot exec 'i686-apple-darwin8-gcc-4.0.0': No such file or directory
lipo: can't figure out the architecture type of: /var/tmp//ccPB9Ubs.out
make: *** [../bin/pd] Error 255

I As you see I use gcc-4.0.0 to compile it. Any suggestions?

Thank you.

Sergio.

Hi all!
I would like to use some objects from a C++ library in my PD object. The point is as far as i know, the PD object must be writen in C and have to have some specific functions. So the point is, if Im implementing my PD object I cannot use the C++ objects I wanted. Another possibility would be to write something in C++ and declare the PD object as extern "C"{} but then I really dont know what would happen, because I never used a PD implementation as a linked object. Would I loose the graphical interface? Should I compile the whole PD in C++?
Any sugestions?

Thank you very much.

Sincerely,
Sergio.

Hi people,
Is it possible to send midi messages from Pd directly to Reason without passing through my soundcard?
The solution I found is to set in the Pd preferences the output device as being my MOTU. Then I connect the output of this MOTU to its input with a MIDI cable (I know this isnt elegant). I turn on the Reason and it receives the MIDI signals. The problem is that sometimes I have MIDI overflow. I imagine there might be a lower level solution that could send the information without passing through my soundcard.
It would be like rewiring Reason to work with Pd.

Any suggestions?

Thank you all,

Sergio.

Hi,
I use PD to work with rhythmic interaction so I need as less latency as possible. I set in the preferences menu 10ms of latency. More then that is too much for my applications and latency starts to become perceptible. But then i realized all the audio output (and in fact, also the input) get cutted in pieces and it is impossible to play something using the PD audio output. Is it a RAM or a Processor problem (I use PowerBook G4 and 768 MB RAM)? Any solution?

Thank you very much,

Sergio.

Hi,
ive noticed something about the [metro] object. If I turn the DSP on the metronome becomes slower and if I move the mouse with the DSP on then it becomes faster. I use a PowerBook G4 and the X Tiger. Is there any other more reliable way of counting the time in PD that isnt attached to the DSP nor to the mouse movement?

Thank you very much,

Sergio.

Hi,
I need to record a sequence of .wav files from an array. At each bang the array is filled up with the information I want to record. But at each bang I need the file name to change in a way I get in the end something like file1.wav, file2.wav, file3.wav...
I have tried the [makefilename] and it works to build the names but then the [soundfiler] doesnt accept just the file name, it needs a message like 'write -wave file%d.wav array'. I tried also to pack the messages 'write', '-wave', 'file%d.wav' and 'array' but then the soundfile object doesnt recognizes this as a writing message.
Does anyone can help me with that?
Thank you very much for your attention.

they do emit the same sound at the same time, but as their distances from the listener varies, they have to be generated by the speakers in different moments. many of them might have a very low loudness energy due also to their distance, but it's important that this generation were done as realistic as possible, although these spaces are imaginary 3 dimensional manifolds.

if you have news about someone who solved this problem in other situations, please, let me know.

thanks a lot for your reply!

Hi.

Continuing the problem... I tried now to compile the Pd-0.39-2 package. It asked me the Wish.app which I installed. Then I got an error which says:

Error in startup script: image not found
while executing
"load $pd_guidir/bin/libPdTcl.dylib"
invoked from within
"if {$pd_nt == 2} {
# turn on James Tittle II's fast drawing
set tk::mac::useCGDrawing 1
# set minimum line size for anti-aliasing. If set to ..."
(file "/usr/local/bin/pd.tk" line 44)

Any ideas?

Thanks.

Sergio.
