OK that changes things a bit. I download midi files a lot. And 90% are terrible. They seem to be re circulated and re edited over and over by in my opinion people with bad taste or no musical background.
Most I think are generated on a Home Keyboard sequencer or buy miss using Band in a box.
You do get lucky from time to time and can tell right away if the sequence was made by a person with actual talent.
I just look for god drum parts which is the hardest to find. Drums are often loops and you can spot BIAB loops by the stupid rolls that are always off time. The drums are often the wrong groove for the song.
The guitar parts are often a joke too. Wheezy saxs pretending to be BU vocals? Piano parts are sometimes the best part of the sequence so I often keep those. Anyhow, most download midi files are not worth the bother to fix.
I will look and have bookmarked many midi sites and if I get lucky I will take that sequence and fix it up. If not,it's faster to make my own.
But if this is what your talking about I totally see what you are getting at.
