Unfortunately setting jack only to capture doesn't help.Jack stops.I've tried many different scenarios in jack but only playback is opened.I've also tried using hw:1 (Roland SP-606) and hw:1,0 (usb audio). In capture-only mode I get the classical: 00:54:29.580 Could not connect to JACK server as client. - Overall operation failed. - Unable to connect to server. Please check the messages window for more info. As for the midi light load feature,I think it's somehow connected to an error message(bug) some SP-606 users (and myself) reported "MIDI Buffer Full!". Thank you for your time. ------------------------------------------------------------------------------ Everyone hates slow websites. So do we.
