Hi there,
Recently jack is supporting running multiple, named instances of the server and thus, theoretically, allowing for using in/outputs from more than one sound card. I found out that in order to use this feature the clients must connect to a specific jack server, therefore they should accept a jack server name argument or somesuch.
Apparently, the only known client supporting this feature is ardour (CVS) and so I had not yet tried it. Are there plans to include this functionality in PD? If so, any time soon?
