It does? I thought it had gimpy vibrato, like always pitchbending it above the note as opposed to around it.
this has been changed to the up/down type in the latest beta, though it's been a real point of contention. some people prefer the string/guitar-style "bends upwards only" kind. i wonder if there is some sort of compromise so that both can be included... a 4xx modifier or something.
I personally had problems with the 4xx vibrato because whenever you went deeper, the higher the pitch went. It annoyed me because since this is a tracker and all, it should act the same way most other trackers treat vibrato.. At least, imo anyway.
