Re: [sc-users] [jack] max amount of channels for Jackosx?



Hi Marije,

thanks for the tip. I see that in linux it is indeed a parameter, set to 256 by default. In OSX it doesn't show up in the JackPilot application though. And the option also doesn't show up in the jackdmp --help.. Maybe it works anyway. Would you happen to know how to run jack from the commandline in osx ? I can't seem to get it running, and there is no documentation about it (everyone on osx seems to use the gui version..).

cheers & thanks,
Wouter

Hi,

I'm researching the possibility to use JackOSX for solving the
problems I'm experiencing with multiple servers on our WFS system. So
far it seems to work, but I'm bumping into some kind of maximum inside Jack. When I try to boot 8 servers with 96 channels output each (which
is what I need for our system) it stops after booting the 4th. I've
set jack to verbose mode and posted the messages I got below. It says
"JAR: Cannot register ports" as most important message. Could anyone
give me a hint on why this happens, and if there is a way around it
(maybe increasing memory size somewhere)?

On Linux there is a parameter in the JACK settings for the maximum number of
ports it can use. This has to be set before you start the JACK server.
I assume there is a similar setting in JackOSX.

So in your case, you'd want the maximum to be 9 * 96 channels. (8*96 for the
scsynths, 96 for the actual hardware ports).

sincerely,
Marije
