Another very handy way to use the patchbay is for automatically connecting inserts in Ardour. For example, I have a patchbay definition that connects Ardour to Jamin; all I have to do to connect it is create an insert in Ardour named "Jamin" (after starting Jamin, of course), and QJackCtl does the rest. Additionally, I have Ardour's master output exclusively tied to outputs 1&2, and no other programs are allowed to use those outputs. That way all the programs I'm using must be directed through Ardour's mixer, either via a bus or captured in a track. -- Sean Corbett __BlacktownSoundLabs__ [http://blacktownsound.com] -- Ubuntu-Studio-users mailing list [email protected] Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-users
