SC_JACK_DEFAULT env too long

Questions
#1

hi, i have a problem with the “SC_JACK_DEFAULT_OUTPUT”.setenv( String).
I need to run this long string (= 1055 char) :

"firewire_pcm:000a9200c6100511_Output 1L_out,firewire_pcm:000a9200c6100511_Output 2R_out,firewire_pcm:000a9200c6100511_Output 3L_out,firewire_pcm:000a9200c6100511_Output 4R_out,firewire_pcm:000a9200c6100511_Output 5L_out,firewire_pcm:000a9200c6100511_Output 6R_out,firewire_pcm:000a9200c6100511_Output 7L_out,firewire_pcm:000a9200c6100511_Output 8R_out,firewire_pcm:000a9200c7030496_Output 1L_out,firewire_pcm:000a9200c7030496_Output 2R_out,firewire_pcm:000a9200c7030496_Output 3L_out,firewire_pcm:000a9200c7030496_Output 4R_out,firewire_pcm:000a9200c7030496_Output 5L_out,firewire_pcm:000a9200c7030496_Output 6R_out,firewire_pcm:000a9200c7030496_Output 7L_out,firewire_pcm:000a9200c7030496_Output 8R_out,firewire_pcm:000a9200c0000774_Output 1L_out,firewire_pcm:000a9200c0000774_Output 2R_out,firewire_pcm:000a9200c0000774_Output 3L_out,firewire_pcm:000a9200c0000774_Output 4R_out,firewire_pcm:000a9200c0000774_Output 5L_out,firewire_pcm:000a9200c0000774_Output 6R_out,firewire_pcm:000a9200c0000774_Output 7L_out,firewire_pcm:000a9200c0000774_Output 8R_out"

The connection fail for the last port; the max size of the string seems to be 1023 char
“SC_JACK_DEFAULT_OUTPUT”.getenv.size → 1023.
How can i fix this problem ?
thank you

Never found this way of working with JACK to be all that useful. Have you considered using a series of jack_connect commands? You might need to install it though…

[
   ["from_here", "to_there"],
   ["from_here", "to_there"],
].do({|v|  format("jack_connect % %", *v).unixCmd })

Merci !
I didn’t know the jack_connect command. I will try this as soon as possible. it seems perfect.

this is great for me !
I need to run:"SC_JACK_DEFAULT_OUTPUTS".unsetenv;"SC_JACK_DEFAULT_INPUTS".unsetenv
before s.boot to avoid autoconnection. and then I run

[
  ["from_here", "to_there"],
  ["from_here", "to_there"],
].do({|v|  format("jack_connect % %", *v).unixCmd })
