Everyone has already chimed in, and I don't even use BandSlab by Snakewalk (sticking with splat for as long as possible), but please we're talking about a plug that has been around since version 6 at least. So over 10 years old. Of course this plug will cause issues...it wasn't a very stable plug in the first place...so combine that with the plugs age and it = trouble. Depending on what you use it for, Wave's has an excellent vocal tuner that if you keep your eyes open will only cost 30 bucks. If you're more after an effect ala Believe...then stump up for the basic Melodyne which is about 90 dollars, but correct me if I'm wrong.
