I have a Creative Labs SB Audigy card with MIDI in/out on the front panel. When I start jack, these show up as 0:Audigy MPU-401 (UART) and 32:Audigy MPU-401 #2. I'm assuming 0 is the MIDI in and #2 is MIDI out. I can't seem to get MIDI in to work when I plug in a synth. I'm currently using Qtraktor and I've connected the Augidy MIDI ports to "master" for Qtractor in jack.
