1:13-1:15br

br
Im pretty sure this bass is utilizing Fm8, but what kind of oscillators and parameters should I be shooting for to get a very deep monster bass like these?br
br
Many of the proficient monster bass tutorials, such as dan larsonns of Loopmasters, produce great growls but they don’t attain this deeper sound Im going for…br
br
Any tips on getting this sound?br
br
Thanks!
