On a competely different note... The kick (and various other drum sound) tutorials in the "Logic Studio Instruments and Effects" manual's Ultrabeat section is a great primer for creating all sorts of tasty drum sounds and once followed through can really help when programming drum sounds in the ES2 or any other synth for that matter... Not to say I wouldn't love to see Steve H's approach, but is another great source of info. I have been dialing in drum sounds for quite a bit of time and I feel that little bit of manual could help expand anyone's palette.
