could you tell which os ,card, platforme , distro you use ?

i use pd ,37 test10 under win2000 sp4 (but it perform perfectly on xp sp1 too on my computer)
i use zexylib,maxlib,iemlib.
i use mmio mode for best latency (i know it's sound really strange but it perform Much better than asio on my gig.)
my card is a rme hdsp9632 with a buffersize of 1,5 (1,415...) ms. (64 block)
whatever value i set on audiobuf or block it stay at 1,5...
i ve made a patch using pd as an effect (decoding live a LtRt movie mix to LCRS (surround))
it was performing quite good in sync with the screen. (indeed one video image is 40ms lenth so with a 1,5ms latency that's ok)

but i heard about the jack low latency driver . id like to know opinion from linux users....
anyway , i should already been on linux but since ive bought that new card , i don't manage to have sound with it , before it was ok with my motherboard chipset AC97 (working huh ) and as far as i remember , it had never crashed under linux against 2 or three times the day with windows, and the cpu consumption was really lower than under zindaube. something like 25 to 40 % less (using windows performance and top on linux .) i understand that this difference come from the graphical management of tck .

I use it with
OSX 10.3, build in soundcard, Pd version 0.37.0, no externals
and I like it.

PD 0.37.1 devel (Planet CRRMA, with some externals - zexy, Gem, iemlib, and more too but I forget what I have installed...) on Red Hat Linux 9 with Planet CCRMA low latency kernel. Audio with Alsa is unreliable but I will set up Jack real soon now (TM). At least I have MIDI working, I'm a Pd beginner so I'm just learning how things work. Before I switched to Linux I was using Windows 2000, Pd was almost unusable, the latency of the GUI when dragging objects was unbearable. I didn't like Windows because it kept crashing, no crashing problems with Linux so far. Hardware: soundcard Creative Labs Audigy, graphicscard GeForce2, CPU Athlon 1.6 GHz.

ho
hell
have to change my plans

pc pIII 866mhz
AC'97 onboard soundcard
intel 3D onboard card
512 Mo
win 2k sp4
pd 0.37
gem 0.888pre

hello

computer laptop : PC packard bell (bios Pheonix ) 700 Mhz, 256 Mo Ram
soundcard: RME hammerfall multiface (yeah!!)
OS: Win 2000 SP4

I dedicace this computer for audio, some blue screen (process_has_not_locked_pages), maybe the RAM.

trying to move to debian 3.1, ARRGGGGRGGGH!
It seems to be a very efficient Linux for audio, but ..... very hard to install.

this days I just want to do music, so NO LINUX, and NO PD. Too hard to do music with it for my knowledge.

I've tried Pd-Knoopix, quite cool but how recognize my sound card with it?

conclusion: Pd 0.37 with all objects (xsample = good, maxlib too) and win 2000 (scheiBe!)

I fixed all my ALSA drop-outs by doing (as root):

# echo "1" >/proc/sys/kernel/lowlatency

To activate the low latency patch (for some reason it wasn't activated, so the kernel wasn't really low latency at all...)

# gedit /etc/sysctl.conf

add the line

kernel.lowlatency = 1

To activate it permanently.

To enable realtime priority: WARNING: BIG SECURITY HOLE

# chown mynormaluser:mynormalgroup /usr/bin/pd
# chmod u+s /usr/bin/pd

Now I can run Pd with -rt and even under heavy load Pd never clicks or skips or drops out - perfect operation!

I still haven't set up Jack...

usefull info !
i'll try this with my debian demudi i dunno if it set realtime by default

have you ever test the dynebolic bootable cd ?
[url=http://www.dynebolic.org/ ]http://www.dynebolic.org/

i have make some try with it, it seems to be real nice, there is jack preconfigured, pd and lot of sound software, maybe it could work with a rme. and this one work with nesting config and files on a usb key for keeping data.

My first step with jack have really amazed me, i love this system, if only i could found a sound editor as powerfull than wavelab i think i'll go definitly with a linux system.

wow
have to try
many thx thx thx...

hi there, any chance you could give me some tips on getting pd up and running on panther osx. it seems to have installed correctly but when i select the pd application icon nothing happens. any help would be great.
