Arp or Composition
I'm unsure of the melody,but there really isn't a melody needed for the genre of trance your aiming for :P
sounds cool, if this is your first composition I'm jealous...I guess Reason 4 is a good program for your first to sound this good!
listen to my first one and compare, you'll be shocked
Anyways good song for a first submision
