I've been trying to use my Microkorg Xl with Samplitude 14 as a MIDI device but can't seem to get it to work. The program recognizes it and I set the MIDI In as the MK XL then I choose Vita as my synth and try and play some notes on my Korg but I get nothing. I'm using the USB connection. Can someone please help me with this? I'm probably overlooking something very simple but would appreciate any input.
