The help files in 2.5 no longer reflect accurately the actual screens. I have a checkbox in the editor marked Turbo LPF next to the Filter Type drop-down. I \'assumed [img]images/icons/rolleyes.gif[/img] \' it meant 18 or 24 dB/octave rather than 12, but it doesn\'t really sound like that to me.

Can anyone enlighten me?
