a cool trick that I use in cubase 2 sorta emulate sidechain comp from a kick into a bassline....

do a volume automation on the bass, so that yer bassline audiotrack dips a little with every kick... (bounce it 2 spare the cpu if needed) u'll probably have 2 use a huge zoom and a lot of copy pasting but should yeld some nice results with a very detailed control over the all thing!!! this uplies 2 basically any audio sequencer.
