Simply layering drumsamples doesn't give you the sound you want? Try this technique. Please listen to the recording (see link below) to compare for yourself (preferably on a system with bass/woofer).

NOTE: FREE downloadable (lowpassed) kickdrumsample (SUB.wav) included in the link below, which you can load into your electribe SX and apply the technique!

NOTE #1: I made the length of the kickdrum extremely long, so you can adjust the length using the decay-param to your liking.

NOTE #2: the basic idea is to send your kickdrum + bassline to one lowpassed bus (e.g. fx3), and compress the other (highpassed) material in the other bus (e.g. fx2)
