384 Chapter 24 EVP88
Tone
The Tone control equalizes the sound before the virtual tube amplifier circuit amplifies
or distorts it. You can choose a more mellow tonal color here, and still boost the treble
with the equalizer after the overdrive circuit. If you prefer harsh distortion
characteristics typical of overdriven transistor stages, use higher tone parameter values.
If the sound becomes too hard, you can defeat the treble via the Treble control, post
the overdrive process.
Gain
The Gain control determines the amount of harmonic distortion.
Phaser
The phaser pedals popularized by electric guitarists are also popular among electric
pianists—especially in the electric jazz, jazz-rock and pop styles of the seventies. Classic
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 called comb-filtering. The frequencies of
the notches in the frequency range are not harmonic and these notches are shifted up
and down through the sonic spectrum by LFO (low frequency oscillator) modulation.
Note: Logic Studio 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 60s and 70s, including subtle analog-style distortion. It offers the same
32 Bit internal processing and sound quality of the Logic Studio Phaser plug-in.
Rate
Sets the speed of the phasing effect. When set to 0, the Phaser is switched off.
Color
Sets the intensity of sound coloration introduced by the Phaser, caused by feeding the
Phaser output signal back into its input.
