The original MIDI is from user harlanlovestone, he was looking for an orchestral vibe, but only after taking his request I realised I didn't have any available quality orchestral instrument to use.
(for a few minutes I had Native Instrument's free demo but the demo had run out before I could export its audio T-T )
Because I still wanted to deliver to him something I tried to work out with what I had...

PS: I wasn't sure whether to put this in cinematic or experimental...
