The filters in the E-mu are awesome. In fact They can save you loads of desk inputs when building a drum track and allow for a subtle or extreme degrees of EQ tuning.
Here is a tip, if you haven't tried it yet...
"Sweep EQ" filters make great EQs when you combine them with a drum bank using c/controllers.
You can have 6 drums with separate sweep and Q, all tweak-able in real time, and produce radical automated mixes that go way beyond those possible from a desk.
You can also set the pan position for each drum, assign the whole lot through a stereo pair and free the samplers remaining outputs for other instruments.
Just remember to set each drum to a different group.
If you need further EQs for more drums sounds
1. Set the Q level manually into the preset, without having a controller assignment for Q (this frees the controllers allowing 12 sweeps)
And/Or
2. Re-sample the results
And/Or
3. Use another midi channel (giving you a further 6 channels to sweep and Q, or 12 to just sweep - making a total of 24)
This adds a new lease of life to old TR808 & TR909 samples, breaks or any other stuff you throw at it.
The way this allows drums to sit in the mix is indispensable, and gives many DAWs a run for their money.
Also try "High Pass Filter" on the kick.
This allows you to cut the low freqencies and drop them back in to stunning effect, a cool trick used to add more interest into a dance track.
