Hi! I'm looking for a way or plugin to use with pro tools 9 to get the bass mono from a certain frequency to avoid anti phase when mastering for vinyl. I know bx_digital masting eq is able to do so I guess it is a little too expansive. I would rather prefer something more easy and freeware if possible as I have a mastering chain already but just this part is missing. All I need is a Hz-knob for the frequency to choose where "bass is mono" starts. Is there any way to do so, a plug or anything else? Any suggestion will be appreciated! Thanks!
