Understandable, but the way I see it is creating a tribute or rendition to the songs, no matter what the notes you use. Moreover, the unique notes are tough to use in most MPC remixes, so most of the time I use the usual notes. I tried using other notes for my MPC songs, but they do not sound well most of the time. Granted, if one would use those particular notes where it is noticeable, kudos. But, I have yet seen it on the more neater and majority of songs. Besides, I believe every note provided by MPC is just as valid as the dog, baby, or pig sounds. Thus it meets the point of using MPC.
Heck, I think all the notes are unique, they're just so wacky XD
As for a type of MIDI maker, meh... I find MPC much more fun and challenging considering the restrictions.
I do however try to make my remixes my uniqueness by at least adding things that are nonexistent in the actual song. Occasionally, I'll add some dogs, cats, etc. into it if it fits.
In this Mega Man song in particular, I threw in some drumrolls and subtle tweaks to make less of a carbon copy to the actual Shade Man.
