Filter sweep entire track

Hello all! I was wondering about the best way to apply a filter sweep effect to the entire track using automation.
I have done some research online and I’m thinking that you can 1) send all tracks to a group channel and then insert filter vst on that channel or to use Sends.

For the first option, what if I have tracks already going to different groups (bass, synth etc)?
The second option I’m not exactly clear on how to use sends to apply a filter effect over the entire track.

If anyone could point me in the right direction it would be appreciated.


Insert it on the master :slight_smile:
