I have about 5 different go-to settings on my envelope-controlled filter, and only 1, maybe 2 of them, are that clichéd funk (sic) auto-wah sound a la Bootsy Collins.
- I often use it as an extreme low-pass or hi-pass filter with no envelope modulation, by turning the Sensetivity and Peaking controls to their minimum. Extreme LP yields a huge deep reggae-type sound with very little pitch definition but tons of bowel-shaking subwoofer gushiness. Extreme HP (especially with the Range control set to high and Drive direction set to up) yields a thin, quiet, tinkly metallic sound...perfect for seeding loops to create pixillated atmospheres that you can then easily play over or under once you've reverted to a fullrange sound.
- Using a bandpass filter with moderate amounts of envelope modulation is a great way to add some subtle animation to what winds up being a fairly normal-sounding grindy rock bass sound...it tends to accentuate the attack without making an overt "blap!" or "quack!" sound.
- just reversing the sweep direction from the traditional Bootsy auto-wah setting yields a sound where gentle playing sounds like completely normal unprocessed bass, but when you dig in the bottom end drops out and you get a delayed attack synthesizer-type "BEEEOOOWWWWWW" as the filter sweeps down and reintroduces the bottom end.
