Hello everyone, recently I acquired a digital piano (KORG LP-350). Problem is once I connect both midi In and Out ports to the Audio interface (M-Audio Fast Track Pro). I get no sound from the Reason program. The only hint that I get that Reason recognizes the piano is that when I play a note the audio track gets highlighted in a bright green color that rises up and then back down once the note has been played. I know the problem isn't the audio interface or Reason application itself since I have tested another midi compatible device with success (MicroKorg). I would really appreciate it if I can get some help from you guys. Thank you for your time.
