Suppose you're working with operator and you set the level of the the first operator and then you apply velocity modulation in the operator shell, so far good but when the note played is at high velocity, the sound produced would go over the set level. This is something that I've never encountered on any other synths I've used. This "issue" is not limited to velocity, it does the same with keytrack as well.

I don't know how others feel about this but I find it as an undesirable trait in all the stock instruments.
