Hi, ive been trying to make heavy bass lines such as those used in productions from Getter, Barron, and Rekoil. Im not trying to replicate their style but I want to know the logic behind their sound design. Can anyone guide me in the right direction in making sounds such as these? Here are some tunes that are MASSIVE with these sounds. It would be much appreciated!
