"The way to do it is to EQ your kicks with very little sub. It gets lost because it's inaudible.
The way to make a kick drum really SPANK in a mix is to kill the lowest sub completely, boost low audibles and some high frequencies. For use on the ES-1, try EQ-ing your favourite kick sound before sampling it or copying it to a memory card and on to the ES.
For a quick and easy example, using a 10-band graphic EQ (it approximates to something that a lot of people have), try the following values:
30Hz - as low as the value can go (I use a setting of -36dB)
60Hz - boost by 1-2dB
125Hz - boost by 2-4dB
250Hz - boost by 2-4dB
500Hz - cut back - I use a setting of -3dB
1kHz - cut further back - I use about -5dB
2kHz - boost by 3-5dB
4kHz - boost by 4-6dB
8kHz - boost by 6-8dB
16kHz - leave at 0dB
You'll need to approximate these for other numbers of bands, or parametric EQs, etc. If it helps, draw a curve on raph paper to see what this shape looks like, then apply that shape to your EQ module/unit/software/plugin.
Also, you may find that the boost a 4kHz drowns vocals out, so you may want to tweak that band down a little.
BTW - these may sound like weird values to use, but seriously, TRY it!"
