Spectral processing bands not frequency-aligned with content
First off, absolutely love it.
Secondly though, has anyone else seen that Spectral mode dynamic EQ bands are not actually aligned to the frequencies they are meant to be affecting? The centre of each Spectral band seems to me to be offset about 20Hz to the left, compared to Pro-Q 4's analyser. v4.02.
I'm pretty sure the analyser is accurate so the question is, is this a display issue only, or are the actual EQ bands inaccurate with regards to frequency?
Or is it just me being dim?

Hi Colin,
You have an excellent eye! This is a display only 'issue' and does not concern processing. We're are applying a type of smoothing in order to visually make a representation of what is happening. Without getting into too much technicality, we're dividing the spectrum into small area's but if a frequency is on the far edges of this area you tend to see an offset. However, this does not affect the processing it merely sometimes looks like the processing is a bit heavier either left or right of the center frequency. We'll try to find a better solution for this in the future.
