U know what you do bro?
You Open a New empty Project in
Logic
Then select audio file......Add you finished track there
Now open another channel and make it an audio file also....in this channel....put the Kick Drum/lo range
But...because you don't want to fk up the sonics of
the original track.....I WOULDN'T suggest EQing the two
tracks to mesh together....because it'll screw up the sound....
BUT what you want to do in this new project.....is Add the Kick where you want.....and 'Duck' the whole music track.... using a tight sidechain compression...with a mid-fast release
And instead of EQing the 'music track' to fit the 'drum track'.....do it the other way around...
Hollow out the drum track using eq....so the music track can easily pass thru without clashing.....(Using a HalfPipe slope in the lo end)
New project and just add the two sound files together. easy peasy
