hi!
i am fiddling around with jack, jackdmp on osx.
i read somewhere here that it would imrprove load and latency of the os.
in my case pd runs better with the built in driver of osx. but then i miss the ability to connect...
i guess i still do it wrong.
if i set buffersize in jack to 512 frames at rate 44100 how is pd to set?
in qjackctl under linux it says 23.2sec at 512frames and nbuffers 2.
if i set that in osx i get bad performance. as soon f.e i use a complex fdn~ subpatch it starts crackling.
so how can that go togehter?
second block of questions:
i tried jackdmp_68.0 on osx. it shows everything in the routing window. (i tried with sc3 and pd,sc3 connects to jackmp)) as soon as i try to select "jack" in the media menu pd vapourizes completely...
if i uninstall jackdmp and reinstall jackosx74 it works sort of. (i did uninstall the jackosx packgage before i installed jackdmp)
help....!!!

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.

oh...thats me!

Just sticking to 0.74 at the moment.

hi
everything works now (not 100%sure why that is....)
i had to completely uninstall pd, delete the pd.list in preferences.
then install pd-ext.40.3 again and i can connect it now in thejack
routing window.
before i tried to uninstall jackosx75b15 with the included uninstal
command but then pd would still look for the jackframework and crash.
weird to me was that even i deleted .pdrc it still had some of the
settings from that file.
Pd-0.40.3-extended-20071220 and jack075b15 working fine.
greets
yann

and...
if i select "jack" driver in the media menu pd crashes on the spot.
if i instead and only select "jackrouter" in audio preferences it works

*bump *

Has this been fixed for anyone?

**double bump**

I can't get sound from jack at all. I can't even start jack with qjackctl. I wish OSX were just a *bit* more like linux. ALSA-OSX anyone?

erm are you using a macintel? if so - internal sound card?

No Intel here, I wish... G4 ppc, TiBook 667mhz with Texas Instruments TAS3004.

I've used jack just fine with Linux and ALSA. To my surprise, when I opened QjackCtl just know, I actually got Jack active with the following;

/usr/local/bin/jackd -R -d coreaudio -p 512 -r 44100 -i 2 -o 2 -d AppleDBDMAAudioDMAEngine:0

I have no idea why the -R is in there, and how Jackd got away with it, but it seems to work with system sounds and Ardour2.

If I choose Jack Router from the audio preferences, PD shows up in jack, but no sound. If I [print~] the matrix, it is all zeroes.
If I choose Jack from the Media menu, complete trainwreck, many many Xruns and Pd freezes.

Yep this happens with me also on my g4 pbook. I've logged a bug in the tracker and Hans is also aware of this. He said that it should be resolved in the next release, though I not too sure which release!! :/ I should get him to clarify.

Bit off topic - have you got your HD partitioned to run OSX or Linux (Ubuntu?)

thanks

Let me just add a comment about the G4 ppc, TiBook 667mhz, as I used to have one: It is atrociously slow under Mac OS X but very usable under Linux (especially Pd!).

well i've got a gig of ram and its a 1ghz machine. It doesn't win any races but its not sluggish to use. Pd works find, but its the GUI stuff that canes it. Appraently the next version uses a better version of TCL/tk and the gfx performance is much improved. Trouble is, i dont know which version that is!...again

Its much much better when running in Jack mode, which unfortunately doesn't work at the moment!!

If Ableton ran under Linux, I would be more tempted to give it a try....sorry!

@Boonier: I've got (@least) 3 machines, the TiBook, a 'Yikes!' G4, and a Pismo Powerbook. All running partitioned, dual boot systems. Distro is Debian, 2.6.23.x with realtime patch.

My main problem right now is that the linux_rt setup works best for audio(Ardour, Jack, PD), while the OSX works best for Video(GEM). This is mainly due to a problem which has been discussed here; Gem crashes unreliably on linux with certain stock graphics cards. I wish this were resolved, so I could use only linux.
