When the resonant peaks of the lowpass filters pass through the overtones of the sound being
filtered, those overtones are reinforced. This gives the filter a nice character that sounds vocal,
quacky, or zappy, depending on how it’s used. When the resonance is turned up past 8, the
filters begin to self-oscillate at the cutoff frequency, producing a sine wave tone. The Keyboard
Control Amount control sets how much the filters’ cutoff frequencies track the keyboard note that is
played. As you play higher on the keyboard, the cutoff frequency goes higher, too.
The Voyager features two filter modes: Dual Lowpass and Highpass/Lowpass
DUAL LOWPASS MODE:
The Voyager’s Dual Lowpass filter mode features two lowpass filters which are routed to the left
or right audio output. The Cutoff knob controls the frequency cutoffs of both filters. The filters can
be set to the same cutoff frequency, or different cutoff frequencies with the Spacing control
(figure 20). When the two filters are set at different cutoff frequencies and routed to two different
speakers, what you hear is a fantastically swirly and vocal sound – sometimes sounding similar to a
phaser effect.
