The Megaman Zero series pretty much my favorite game series (Final Fantasy might take its place though...but it has some really weak games *cough8-11cough*).
Like AuralMuser said, the pitch on the melody is too low (it's in the wrong key - sounds like a fifth off). There were a couple of missing bass riffs, but then again, you are limited by 8-bit.
Wow! I've been searching long for a good remix/arrange of this song! I'm glad I found this!
This is IMPRESSIVE!!!
I always have loved this piece; such power and emotion contained in it, especially in the context of the game. Glad to hear it remixed by you. Guess my request pushed you to completing it, huh? :)
While it is not perfect, it is QUITE good, and I think you aren't giving yourself enough credit. My two areas where I feel it was lacking was the phrase at :27. The melody's pitch, while not wrong or dissonant, I wish was higher, to match the same notes as the original, and the harmony loses some of the energy and darkness too. Maybe I'm just being harsh here, but the phrase loses some of the original force.
The other part is the transition from 1:09 to 1:10. I think the key change you made further back left the original's key, which is fine, but then you return to the original's key at 1:10. So it was a bit disconcerting.
Other than that, great work! I know this was a tough one for you. The start and ending of the song have great energy and retain the original's desperation, and while the middle is a bit weaker it still stands strong. I would have liked more percussion but I think that is an 8-bit limitation that you are sticking with, so it's all good. Very enjoyable!
I didn't realize just how close I was to getting a finished product out the door when I originally talked to you. You did however provoke me to revisit it and employing some of my new skills resulted in this. :P
I'm honestly not sure what to say about the key changes, because I ripped the midi directly from the games--And that part of the notes was unaltered except in pitch. The pitch was much lower in the ripped midi, so I had to manually shift the sample root to get a higher pitch out of my instruments. Perhaps I didn't shift it quite enough?
Please contact me if you would like to use this in a project. We can discuss the details.
