The EVP88 features built-in Equalizer, (Over)Drive, Phaser, Tremolo, and Chorus effects. See these sections for details:
The Equalizer allows you to boost or cut the high and low frequency ranges of the EVP88 sound. The Equalizer is positioned after the overdrive circuit in the EVP88 effects chain.
Tip: You can achieve a very direct and aggressive sound, with a more dominant mid-range, by suppressing the treble and bass frequency ranges. If you require more precise equalization, you can insert any of the Logic Pro equalizer plug-ins into the instrument channel strip. You can also use the Tone control of the Drive effect to further contour the harshness of your sound.
Electric pianos sound best when played through tube amplifiers. Tube amplifiers offer a wide range of tones—from the subtle warmth or crunch of guitar amplifiers, to psychedelic, screaming rock distortions. The EVP88 Drive effect simulates the saturation characteristics of a tube amplifier stage. The Drive effect is the first signal processing circuit in the effects chain of the EVP88.
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 Pro 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.
A periodic modulation of the amplitude (level) of the sound is known as a tremolo. The modulation is controlled via an LFO. The Fender Rhodes suitcase piano features a stereo tremolo, and many other electric pianos have a simple, but quite obtrusive, mono tremolo, which can introduce a strange kind of polyrhythmic feel to performances.
Tip: The original Wurlitzer piano has a mono tremolo with a fixed modulation rate of 5.5 Hz. For an authentic Wurlitzer sound, select a Stereophase value of 0 degrees. For Rhodes sounds, set the Stereophase value to 180 degrees. The settings in-between result in nice, spacey effects—especially at low LFO rates.
The well-known chorus effect is based on a delay circuit. The delay time is modulated by an LFO. The delayed-effect signal is mixed with the original signal. It is the most popularly used effect on electric piano sounds.
The single Chorus parameter regulates the intensity (the amount of delay time deviation). The LFO rate is fixed at 0.7 Hz, but it can be altered with the Chorus Rate parameter (see Using the EVP88 Extended Parameters below).
Note: High values may result in the piano sounding detuned.
