updating PD
by joseph moore 19 Jan '04

19 Jan '04

OK, I know this is an easy question. I have PD extended .37 installed on my mac running OSX 10.3. I want to update PD to .37-1test so I can use jack. My very is question is this: what is the best way to update, what files should get replaced and where? Very new to anything that requires more than a simple click install so bear with my very newbie question. Thanks, Joe _________________________________________________________________ High-speed usersbe more efficient online with the new MSN Premium Internet Software. http://join.msn.com/?pgmarket=en-us&page=byoa/prem&ST=1

PD with jackd non-power of two buffer size
by Daniel Hawthorn 18 Jan '04

18 Jan '04

Hi list, I've got jackd up and running (with some modifications) using a frame size of 441, sample rate of 44100, and 3 periods/buffer on a M-Audio Quattro. This works fine for (for instance) fluidsynth, but PD gives me repeated "Partial read" errors. Does anyone know how to correct this so that I can run PD using jack on my Quattro under reasonable latencies? Any help would be appreciated. -Daniel

Weirdness & Linux version 0.37.1
by Brad Kligerman 18 Jan '04

18 Jan '04

Try the following using "Pd version 0.37.1 devel" for linux... 1- Create a patch with a _Hslider_ controller entering a name in the _receive-symbol_ properties box. 2- Save the patch, close and then re-open it. 3- The _receive-symbol_ variable is copied into the controller's _name_ variable. This is reeking havoc with my patch's interface. It doesn't happen on my Window's build, nor with Vslider or any other controller that I use. Any ideas on how to get around this? Thanks. /brad

I have tested it in Linux and it it seems to be working now, but I would appreciate if someone could compile it for Windows since I haven't been able, yet, to build PD in Windows (any pointers on this would be appreciated too ;).

pthread_setschedparam problem on OSX + fix
by cgc 17 Jan '04

17 Jan '04

I've been meaning to post this change for a long time, and have been negligent about it. The pthread_setschedparam() hack that helps pd's audio not drop on OSX is absolutely fatal when used with GEM. The reason for this is that OSX uses OpenGL for the entire UI and GL requires context switches to handle multiple applications sharing the hardware. When Pd sets it's pthread priority higher than the UI, this context switch can be blocked resulting in a complete lockout of UI events as GEM grabs all the CPU resources and refuses to relinquish the context. The fix is to add the -rt option as prerequisite and not make this the default action (a check to make sure GEM is not loaded would be good to have as well): #ifdef MACOSX if (sys_hipriority) { struct sched_param param; int policy = SCHED_RR; int err; param.sched_priority = 80; // adjust 0 : 100 post("pd: real-time mode - using pthread_setschedparam\n"); err = pthread_setschedparam(pthread_self(), policy, &param); if (err) post("warning: high priority scheduling failed\n"); } #endif /* MACOSX */

by Roman Haefeli 17 Jan '04

17 Jan '04

I'm looking for an object like the [curve~]-object in max/msp. If there isn't any, I'd like to create something similar, but for this I would need an [pow~]-object (like [pow], but for signals. Or is sombody fit in maths and knows how to create a [pow~]?
