Logic Tutorial: Busses, Compression & Glue – Step-by-Step

Logic expert Alex Holmes concludes the latest tutorial with a look at using busses, compression and glue…

13: To add a simple top layer, we duplicated the sub track, then made some tweaks to the sound to make a brighter and more interesting version. As this is a higher sound, we can add some chorus to increase the width.

14: To keep this sound in check, we’ve rolled off the lows below 100Hz, and dialed in some moderate compression. We’ve also got the duplicated sidechain compression from the sub, but have pulled it back a bit so it’s more subtle.

15: We now want to tie the parts together so the next step is to send both of the bass sounds to a buss, and both of the kick channels to a separate buss. That way we can process them as a whole.

16: On the bass buss, we’ve added a brightening EQ, subtle drive, tight room reverb and high frequency widening, and on the kick buss some brightening EQ, gentle compression and a little drive.

17: Depending on what other elements are added next, we might now send both busses to a kick and bass buss. For simplicity, let’s just add an SSL-style glue compressor to the master output to duck two or three dB and gel the two together.

18: One final tip and a great way to test the clarity of the low end, is to cut out all the highs on the master output using a LP filter, and listen to whether you can hear both the sub and the thump of the kick.
