Looking at your last (private) message:
The audio doesn't stall per se, it's more like values aren't getting updated consistantly so say a pitch sweep will "jump" along with the numerical input.
... it's sounding more and more like the real-time issue that Miller pointed out. A pitch sweep shouldn't be interrupted like that, in my experience, unless you have some other processor-greedy apps running at the same time.
However, the performance of Aqua Tcl/Tk doesn't help things, either. Controls like number boxes cause a bunch of screen-redraw interrupts that are themselves greedy. Part of it is apparently AquaTk canvasses still use QuickDraw.
Still, the stated specs on your machine should be able to run PD fairly well, as long as you minimize the screen updates on patches where you demand good audio performance.
And I agree, jMax 4.0 has a very attractive, seductive screen interface. Pity it crashed the first time I tried to turn on DSP. :-/
I think there's a lot still to be optimized in the MacOSX port, though, both in user experience and in performance. Chris Clepper wrote recently about compiling with different optimization settings. Might be worth a bit of experimentation...

Hmm...
So it's a Tcl/Tk thing, or a getting Tcl/Tk to work well with Pd thing?
Honestly at this point I'd rather use Pd (more active community, developed well and often, seems a bit more avant guard, etc.) but I'm really only interested in real-time tweaking... If there's a chance things could improve I'll pursue Pd but if that's just the way Tcl/Tk is on OS X I'll go with jMax also.
Is Tcl slow on the linux platform? Early jMax and early Pd were both dog slow on my linux PII 200 last yearish...
JMax has a nice interface (java anti-aliasing etc.) and it's actually being developed pretty intensly. 4.0.0 is looking good.
thanks Adam, Miller et.al, -ryan

Okay, if you're running such a recent Tcl/Tk, it's not the bug I was alluding to, and more like what Miller mentioned. The current Tcl/Tk's are hard to work with because the screen interrupts can cause skips in the sound buffers.
It does run pretty well if you do *not* rely on live updating numberboxes and the like. You can always increase the buffer size by one notch, too.
I've just downloaded jMax, but I haven't had a chance to test it. It sure looks a lot prettier, though. Sigh.

Hi,
Thanks for that tip.
I am using 8.4.1 just compiled last week. The
audio
doesn't stall per se, it's more like values aren't getting updated consistantly so say a pitch sweep
will
"jump" along with the numerical input.
A friend told me Pd on osx runs better than jMax. This hasn't been my experience at all so I thought
I'd
get some feedback from other pd osx users.
thanks again, ryan

If you're running Jaguar and are experiencing a stalled graphical interface, do make sure you're running the latest (8.4.1) Tcl/Tk. The most recent builds at Sourceforge are nice
looking
(antialiased text... which may not help performance). Mac OSX 10.2 introduced some issues with older versions of Tcl/Tk which have subsequently been fixed.

Stalled audio input is another matter. I have an iMac with similar specs, and it's tricky to get good performance.
Best of luck, adam

Hi there,
I read that Pd is "(somewhat shakily) running on Macintosh OS/X" and decided to give er a try...
I
was
wondering if one of the "shakes" is jumpy
unresponsive
mouse input? When clickin on a number object
and
moving the mouse up and down, there appears to
be
certain freezing and skipping in the interface
(also
observable in audio output).
Is this the state of affairs or do I have
something
mis-configured, I have a G3 400, 512mb ram,
OSX.2.1.
thanks, ryan
