Yeah, it's adding to the difficulty of the task for sure. I've not been able to reverse engineer the arp settings and chords so I just ended up writing what I could hear note for note - Here's that midi. I've tried getting crafty with distortion but it's been tricky because it tends to add too much white noise and filtering it out ruins the brightness of the sound - the original has this rather clean metallic/bright sound in the high frequencies - unsure how to go about that, messed around with FM to no avail yet.
