The Launchpad is just a MIDI controller = with some lights and some buttons. My intent is to set this up without = any monitor or keyboard, and then use the buttons on the Launchpad to = control recording and playback from the various channels on the = Scarlett. Here's where I'm looking for help: what can I do to get independent = access to the six channels on the interface? Is there maybe some = combination of sndio / oss / alsa / jack that will nicely present each = channel as a device?=20 Thanks, JD
