On that note, is there a JACK command-line utility that is as easy to use as "|"? That would be cool, if a, b, and c were JACK-enabled applications: $ jack-pipe a : b : c So much faster than opening up qjackctl and making connections manually. Okay, clearly this doesn't handle multichannel very well however.
