m-audio x-session, are the eq knobs all center detent?

[J.R.]

yeah, just want to know if the 4 rows of knobs are all center detent (at 180°) or not. I don't find anything in the net regarding this question, so maybe somebody have one and could tell me...

thanks

rows 2 and 3 are, 1 and 4 are not
