i'm all new to pure data(allready in love and hooked), read some manuals en tutorials for about a week now and this is probably my fourth patch, so maybe i'm doing something really stupid and obvious(hope so).

i'm expiriencing these pops&clicks with everything that changes in the patch. it's hard to discribe for me in english but in this case(but happens with everything) a phasor~ melody is gong into a bpf~ wich centre frequency is randomly changed every 100ms/200 ms(it doesn't matter) now every time the center frequency is changed there is a click or pop coming thru my speakers. some louder than other.
try'd lowering the output volume wit *~ 0.5 for instance but this didn't work.

my delay time is set to 50 ms but even changing it to 500 ms doesn't change a thing.
this happens as well when using my internal soundcard as using my fasttrack pro.
im using pd40.3 extended on a 2.4ghz 2gb ram macbook pro.

Well maybe we could have an informal meetup somewhere or somesort? I can probably sort some space in the building where i work....

but my computer has a cracked logic board which i can't fix right now, so i don't know what i can do.

Ah sh*t that is a bummer. ISn't that a new Macbook (pro)? Ouch. Under warranty? If not, dont even think of getting some company to fix it - you might as buy a new laptop....Unless you feel confident in sourcing the part and getting the tork screwdrivers out (its actually not too hard)

Blo*dy Apple. I've had logic boards fail repeatedly. My multiple friends' Macbook hard drives have started making a loud ticking noise and just failed. I thought Apple were through all that

hello,

i really twist my mind over this for a longer time... i tried many different buildups but nothing worked so far

this is what i did:
i built a very simple patch of a selfcontrolled feedback in pd

the things i use:
-macbook pro
-pd
-2 piezos (mics) soldered on a cables with jacks
-metalplate

a piezo:

so i attached the 2 piezos on the metalplate, plug one jack in the line in, one in the line out and start the patch.

theres one piezo used as a mic and one as a loudspeaker (together with the object) both are attached on the same metalplate.

the circle is closed... there is a feedbackloop that goes through the object and through my computer.

when i talk or make other noises i can feed the feedbackloop...

the pd patch controls the feedback so it wouldnt grow to much, the aim is to get the larsen tones:

http://en.wikipedia.org/wiki/Audio_feedback

....this works really fine with my macbook pro because of its build in headamplifier.

i really can hear my voice and all the high frequented noise i make (the piezos have got a spectrum of 2900 ± 500 Hz)

now i want to plug more of these together. for this i use a m-audio 1814.
but i just hear a feedback, no voice or noises. sounds like they were cutted out.

i tried:
-the mic preamp
-the headphoneamp (it has got 2)
-an external booster
-different buffersizes with jackpilot
-different delays

NOTHING...

whats so special about the macbook preamp ? or is m-audio just lame ?

greetz...

for the first time in a year or so, i am trying out some gem visuals, and it all used to work fine on my old powerbook,

but now, on a macbook (not pro, os 10.4), [pix_texture] is not really working properly. it will play SOME of my jpgs, but most of them return a 'GL : invalid value' error.

i read a lot of mailing list archives and internet pages, and some people suggested turning on mode 0 or mode 1, quality 0 or quality 1..etc but nothing works.

is anyone here using gem on a macbook? do you also get this problem? any solutions?

Summary: JackOSX 0.75 crashing Pd 0.40-2
Initial Comment:
The latest beta of Jack for Multiprocessor support: http://www.grame.fr/~letz/JackOSX.0.75b15.pkg.zip
Is crashing the latest version (autobuild) of Pd-extended 0.40-2 when Jack is selected from the Media menu.

Search the forum for setting up Jack, its a FAQ - basically let Pd do it's own configuration and set everything from inside jack.

...and use Jack OSX as your audio driver, regardless of whether you're using a soundcard or built-in.

Portaudio seems to be buggered. Pd natively supports Jack

Hi guys!
I've been running the "old" version of Pd-extended (38.something) on an Intel Macbook for about two months now and recently switched to the new version (39.3). But as you may have guessed from the title, there's a huge problem now I didn't have with the older version: I'm getting glitches in my audio output, ranging from clicks to longer "buzzy" sounds, whenever I set my Creative Xmod external soundcard as the output device, the Macbook's internal output works normal.
And no, it's not a CPU problem, since I was smart enough to download the Intel version of Pd-extended and I didn't have this problem with the old version which was ppc only if I recall correctly. Also, I'm getting those glitches even with the simplest [osc] to [dac~] patches.

This is starting to drive me insane. Any help would be kindly appreciated.

By the way! WHY does Obi's patch here require 20% cpu load on my 2.4ghz dual core macbook pro, but only 8% on my 1.5ghz G4???? Anyone else able to see this?

people seem to have got it going...here check the mailing list archives
