Just downloaded and going to listen to all of them to see if I would change anything or if they are satisfying as they are. Oddly enough though your '015 Theme 04' is so close to the version I made I really about cannot tell the difference until the 40 second+ mark where you added in harder/louder drum effects. might not have been that bad for some, but I have severe OCD and it was driving me nuts listening to them on loop.

I also went in and edited the Meta Data manually and picked my own looping point within 1/1000 of a second, as some of the loops in the original had just a very tiny hiccup. I added no other effects other than to make sure they were sound balanced across the board as much as possible (unlike how some of them were louder than others, so playing the BMG at 100% might have felt too loud.) I did like you and took the original midi files, but I converted them to Stereo and added 4 more sound channels to them so they sound almost exactly like the original(just better/crisper). I don't know who they got to do it, but they made all the track sound so hollow and overdid a lot of the echo/hollowing effects. I did the same thing back in 2014 when I got the garbage 'remastered' OST.
