Hello Everyone,

I have a complex synth bass track with a stereo field on the top which I would like to retain, but I would like to make sure all frequencies maybe 500 Hz and below are mono.   

Was wondering what the easiest way to achieve this is.   
 
If it was a flat bass sound, I would use the interleave "mono" button, but can't here.

Thanks!

Put a filter on for 500 and below and bounce to a new track, then change the filter to 500 and up maybe? Would you give a track for each to what you want with. Probably better ways though.
 
 

You could use two aux tracks, one with a highpass, one with a low, and process however you like.

Watch out for phase cancellation if you sum to mono. Might need to use channel tools to add delay to either the l or r side if you find you're getting cancellation.

You could check out Mongoose from Boz Millar of Boz Digital for an idea.

Had not heard of that one. Looks very similar in function / purpose. Good find!

+1 to Bozlabs Mongoose

Ozone 6 and 7 have a multiband "stereoizer". Let's you narrow or spread individual frequency ranges.

Take any EQ with a mid/side setting (graphic or parametric)... put it on your master bus, pull down the bass frequencies in the side channel, maybe push it up a little in the mid channel to compensate.
 
Not sure if Sonar comes with such an EQ - I use Fabfilter Pro-Q 2. Voxengo offers a couple of free EQs that allow mid/side adjustments too.

+1 for Ozone Imager module. That way you have control over what bass frequencies are narrowed all the way to mono if you want.
