Drive effect parameters
On/off button: Turn the Drive effect on or off.
Drive mode switch: Switch between two types of distortion effect.
Gain knob and field: Set the amount of harmonic distortion.
Tone knob and field: Equalize the sound before amplification or distortion by the virtual
tube amplifier circuit.
Use low Tone values to set a mellow tonal color. If the sound becomes too soft,
boost the treble portion of your sound with the EQ Treble control.
Use higher Tone values for harsh distortion characteristics, typical of overdriven
transistor stages. If the sound is too aggressive, suppress the treble portion of your
sound with the EQ Treble control.
Logic Pro Vintage Electric Piano Chorus effect
Chorus is the most commonly used effect on electric piano sounds. The Vintage Electric
Piano 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.
Chorus parameters
On/off button: Turn the Chorus effect on or off.
Rate knob and field: Set the speed of the Chorus effect, in Hz. High values may result in
the piano sounding detuned.
Intensity knob and field: Set the intensity of the Chorus effect. Technically, this sets the
amount of delay time deviation.
Logic Pro Vintage Electric Piano Phaser effect
The Vintage Electric Piano Phaser effect is based on analog phaser pedals used by electric
guitarists in the 1960s and 1970s, including the subtle analog-style distortion typical of
these units. These phaser pedals 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 Vintage Electric Piano frequency spectrum. This filtered signal
is slightly phase delayed and mixed with the original signal, resulting in 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.
