starting to get frustrated!!! with the whole bass thing help please please

Hello all I now purchased a “drum&bass” Kit installed properly I hope and to no avail still no bass is it defective ?? What am I doing wrong ?? Do any of the factory presets have bass why can’t I hear them

Drum & bass is a genre and it is a drum kit designed for the drum & bass songs - they are literally a snare drum and bass drum there is no bass guitar in any of the stock beats or premium content library. You can listen to samples of each of the kits and songs and you will not find any other instruments but percussion.

if you want songs that have bass lines along with the drums, download this:
(there are others… you should try several)

then, down any songs that say “with bass”:

that should get you started!
