PS it is nowhere near 3am yet lol.
You could play your audio in some DAW software such as Sonar or Reaper and record MIDI from your KN7000 over the top of it. However, you'd have to learn the software and in my opinion a tablet is a bit underpowered for that sort of software, you might get lag. KN7000s sequencer is made for doing just what you are trying to do and (whilst it is a bit of a process) it does keep it neat and 'simple' in my opinion... once you have figured it out.
