Note: Logic Pro offers a sophisticated Phaser effect (and other modulation plug-ins) that
can be used alongside, or to replace, the integrated Vintage Electric Piano Phaser effect.
Phaser effect parameters
On/off button: Turn the Phaser effect on or off.
Rate knob and field: Set the speed of the phasing effect. The rate is set in Hz values, or
bar/beat values when the Sync button is turned on.
Sync button: Synchronize the Phaser effect to the host application tempo. The Rate
knob sets bar and beat values, including triplets.
Color knob and field: Set the amount of Phaser output signal that is fed back to the
effect input. This changes the tonal color of the phasing effect.
Stereo knob and field: Determine the relative phase shift between the left and right
channels.
At a value of 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.
Logic Pro Vintage Electric Piano Tremolo effect
A periodic modulation of the amplitude (level) of the sound is known as a tremolo. This
modulation is controlled with an LFO in Vintage Electric Piano. The Fender Rhodes suitcase
piano features a stereo tremolo. Other electric pianos have a simple, often obtrusive, mono
tremolo that can introduce an unusual polyrhythmic feel to performances.
Tremolo effect parameters
On/off button: Turn the Tremolo effect on or off.
Rate knob and field: Set the speed of the tremolo effect (LFO frequency). The rate is set
in Hz values, or bar/beat values when the Sync button is turned on.
Sync button: Synchronize the Tremolo effect to the host application tempo. The Rate
knob sets bar and beat values, including triplets.
Intensity knob and field: Set the amount of amplitude modulation.
