You're right about this one -
http://www.vgmusic.com/music/console/ni ... ITY_18.txt - it's awful. I deleted it. I've deleted other files by that guy before too, so I don't know how that one got past me - some do sometimes...
And that's just the thing... the staff here aren't omnipotent by any means. We're actually (in my opinion) understaffed and have a lot of midis to get through. I'm the
only active updater, for a start. And while we strive to familiarise ourselves with many soundtracks (or at least I do, I'm always seeking new OSTs irrespective of having played the games... can't speak for others), our knowledge isn't entirely encyclopaedic, and in many cases when updating we just go with our intuition on what sounds like its been well sequenced.
Sometimes stuff does slip through the net like the aforementioned file, so you are encouraged to point things like this out (read the sticky on this board), and we (probably I) will broach it on a case-by-case basis. We don't have pride and won't be offended by it. In a perfect world I'd make an effort to listen to the original version for every midi cover I listen to, but in practice that isn't feasible time-wise, and will just mean the site never gets updated. It already doesn't get updated often enough.
The other "bad" midis you listed aren't bad enough to delete. The Sonic R one, while inaccurate compared to the second one, isn't appalling - and actually the other Sonic R one is completely missing the melody line on some devices - probably due to use of Roland variation banks without using a proper MIDI reset... that's my guess without investigating. Similar sort of story for the Pokemon ones... they're kinda poor, but they were added some time ago, and they're not so awful that they should be removed.
Naturally, complaining about the quality of files in the new-files is pointless unless you complain directly to the sequencer, because that really isn't anything to do with us until it gets added.
I have not taken into account who made the bad files, I make no personal offence to them. Whoever made them is unimportant, what matters is that they were accepted in VGmusic when they shouldn't have been.
It's entirely important who made them. The files don't become property of vgmusic once they're accepted; we just host them. They take responsibility for their goods (or craps, whichever the case may be). Bad files reflect on the archive as a whole, so the really crap stuff is deleted somewhere along the line (generally speaking), particularly amongst new submissions - that is, anything I deal with.
