EarthQuaker Devices’ Interstellar Orbiter was designed for Kid Koala to be used on his Satellite Concert tour. It’s a dual resonant filter controlled by a single LFO that sweeps each filter in opposite directions. It has three universal controls: a master frequency control that governs the center frequency of both filters, a master rate control for the LFO and direct control for blending in the unaffected dry signal. There are expression pedal jacks for both the master frequency and LFO rate. Each filter is voiced differently and has controls for LFO intensity, resonance and mix. It can do everything from wah emulation to complex vocal formant filtering, and even outlandish rotary speaker effects. You can create very vocal sounds by using the LFO to control both filters, and by fine-tuning the resonance, intensity and master frequency.
