Tone knob: Equalizes the sound before it is amplified or distorted by the virtual tube
amplifier circuit. You can use low Tone values to set a mellow tonal color. If you find
that the sound is too soft, boost the treble portion of your sound with the Equalizer
effect. If you prefer harsh distortion characteristics, typical of overdriven transistor
stages, use higher Tone parameter values. If the sound becomes too hard, you can
suppress the treble portion of your sound with the Equalizer effect Treble control.
Using the EVP88 Phaser Effect
The phaser pedals used by electric guitarists were also popular among electric
pianists—especially in the electric jazz, jazz-rock, and pop styles of the 1970s.
The Phaser effect runs the original signal through a series of four filters that enhance
particular aspects of the EVP88 frequency spectrum. This filtered signal is slightly phase
delayed and is mixed with the original signal, resulting in frequency “notches in the
frequency spectrum. The notches in the phase-delayed signal are moved up and down
through the frequency spectrum by an LFO (low frequency oscillator) modulation. This
results in the amplitudes of the two signals reaching their highest and lowest points at
slightly different times.
Note: Logic Studio offers a far more sophisticated Phaser effect (and other modulation
plug-ins), which can be used instead of, or in conjunction with, the EVP88’s Phaser. The
parameters found in the EVP88 Phaser have much in common with the best analog
phasers of the 1960s and 1970s, including subtle analog-style distortion.
Rate knob: Determines the speed of the phasing effect. When it is set to 0, the Phaser
is turned off.
Color knob: Sets the amount of the Phaser output signal that is fed back into the Phaser
effect input. This has an impact on the tonal color of the phasing effect.
Stereophase knob: Determines the relative phase shift between the left and right
channels, ranging from 0 the effect is most intense, but not stereophonic. At a value
of 180 the effect symmetrically rises in the left channel while falling in the right channel,
and vice versa.
