Gain
The Gain control determines the amount of harmonic distortion.
Phaser
Phaser pedals used by electric guitarists are “classic” effect tools for electric pianos as
well—especially in the electric jazz, jazz-rock and pop styles of the seventies. Classical
four-stage phasing effects are based on phase shifting using modulated all-pass filters.
Mixing the phase-delayed signal with the original signal results in characteristic
notches in the frequency response curve, also known as the comb-filter effect. The
frequencies of the notches in the frequency range are not harmonic (as with the
resonances known from the flanger effect), and these notches are shifted up and down
through the sonic spectrum via LFO (low frequency oscillator) modulation.
Note: Logic offers more parameters in its Phaser and other modulation plug-ins. You
can use these effects alternately to, 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 60’s and 70’s, including subtle analog-style distortion. It offers the same
32 Bit internal processing and sound quality of the Logic Phaser plug-in.
Rate
Speed of the phasing effect. When set to 0, the Phaser is switched off.
Color
Intensity of sound coloration introduced by the Phaser, caused by feeding the Phaser
output signal back into its input.
Stereophase
Relative phase shift between the left and right channels, ranging from 0° to 180°. With
0° selected, the effect is most intense, but not stereophonic. With 180° selected, the
effect symmetrically rises in the left channel while simultaneously falling in the right
channel, and vice versa.
