[PD] Re: Artnetlib multiple IPs

[Lucas Cordiviola]

Hi Simon,

Is there a way to send different universes (or even the same) to 
multiple IPs with artnetlib? If I simply create another artnetudp 
object I get an "artnetudp: socket bind failed.“ error in the console.

strange i don't get the "socket bind failed.“ with 2 [artnetudp]. tested 
on Windows11 and Debian13.

eventually you can use [trigger] objects to address multiple ips or 
universes. see attached .pd file.

also if needed (and if you have an github account) you can open an issue 
on the repo:

The alternative is to use the 192.x.x.255 broadcast address, and simply send 
everything to all nodes, is this the preferred way for every situation with 
more then one node?

Thanks for any insights,

Simon
