So,

Do you guys use sub bass as part of each particular sound you make (for example one of three oscillators would be a sub bass), or do you have just one track for sub bass and modulate it in accordance with the rest of the bassline?

So when i have like 10 separate bass tracks with different patterns plus a sub bass track, i should low cut the modulated bass tracks like at 100hz and leave the rest for sub bass?

So do people use sub bass under EVERYTHING? If i created 130bpm dancable beat and added some filthy basslines to it with massive and some wobbles with scream-filter, would I still have to add an additional track just for the sub bass?
