Vintage Clav Modulation effect in Logic Pro for Mac
Vintage Clav features a choice of three modulation effect types Phaser, Flanger, or Chorus.

Modulation effect parameters
On/off button: Turn the Modulation effect on or off.
Mode pop-up menu: Choose Phaser, Flanger, or Chorus as the modulation effect.
Intensity knob and field: Set the depth of the phasing, flanging, or chorus effect. Use of high Intensity values leads to ensemble-type effects when the Chorus effect is active.
WARNING: When the Phaser effect is active, high Rate and Intensity values lead to very deep, self-oscillating phase shifts that can damage ears and speakers.
Sync button: Synchronize the Phaser or Flanger effect to the host application tempo. The Rate knob sets bar and beat values, including triplets.
Rate knob and field: Set the speed of the phasing, flanging, or chorus effect. The rate is set in hertz values, or bar/beat values when the Sync button is turned on.
