Amp Designer tremolo and vibrato in Logic Pro for iPad
Tremolo and vibrato are controlled by several switches and two knobs in the Modulation FX section. Tremolo modulates the amplitude or volume of the sound, and Vibrato modulates the pitch of the sound.
Note: The Effects section is placed before the Presence and Master controls in the signal flow and receives the pre-amplified, pre-Master signal.
Modulation FX parameters
On/Off switch: Turn the tremolo or vibrato effect on or off.
Type pop-up menu: Tap to choose either Tremolo or Vibrato.
Depth knob and field: Set the intensity of the modulation for either tremolo or vibrato.
Speed knob and field: Set the speed of the modulation in hertz. Lower settings produce a smooth, floating sound. Higher settings produce a rotor-like effect.
Sync Mode buttons: Choose Sync to synchronize the modulation speed with the host tempo. Choose Free to set values in Hertz with the FX Speed knob. In Sync mode, you can use the FX Speed knob to set the modulation speed to different bar, beat, and musical note values (1/8, 1/16, and so on, including triplet and dotted-note values).
