Thanks man
Bass should come out fine during mastering, I tucked a pad sound under the mix but think I might have set the level a touch too low. Both sounded fine once a bit of mastering compression was applied, so hopefully should get the intended result.

Don't use any of the cubase compressors much, I use the built in channel EQs quite a bit though when I'm mixing stuff together for the first time. Quick, easy and doesn't tax your processor at all.
