Running filter fades inside the performing rig removes the need to rely on the house mixer for energy control
Instead of using channel faders on a house mixing desk, a performer can use lowpass and highpass filters built into their instruments to bring elements in and out. Keeping the mixer as a pure summing device and performing all volume and energy changes with filters means the performer retains full control regardless of the house setup. Lowpass filters fade hi-hats, snares, and rides; a highpass filter removes (or nearly removes) the kick drum during breaks. The technique also exploits the musical character of filter sweeps — elements don’t simply disappear, they are sonically shaped as they exit. A practical constraint is that each instrument or bus needs its own controllable filter.
Examples
Lowpass cutoff on percussion buses to fade out hi-hats and snares; highpass on the SP-16’s kick bus to pull the kick during a breakdown while the kick waveform remains at low frequencies.
Assessment
Explain the audible difference between fading a hi-hat with a channel fader vs. a lowpass sweep. Then patch a highpass-out-the-kick breakdown for a four-bar phrase in a Eurorack or VCV Rack context.
