Use the Logic Pro Ringshifter envelope follower
The oscillator Frequency and Dry/Wet parameters can be modulated with the
internal envelope follower—and the LFO (see Use the Logic Pro Ringshifter LFO).
The oscillator frequency even allows modulation through the 0 Hz point, thus changing
the oscillation direction.
The envelope follower analyzes the amplitude (volume) of the input signal to create a
continuously changing control signal—a dynamic volume envelope of the input signal.
This control signal can be used for modulation purposes.
Envelope Follower parameters
• Power button: Turn the envelope follower on or off. When it is turned on, you can access
the following parameters.
• Sensitivity slider and field: Determine how responsive the envelope follower is to the
input signal. At lower settings, the envelope follower reacts only to the most dominant
signal peaks. At higher settings, the envelope follower tracks the signal more closely
but may react less dynamically.
• Attack slider and field: Set the response time of the envelope follower.
• Decay slider and field: Set the time it takes the envelope follower to return from a higher
to a lower value.
Use the Logic Pro Ringshifter LFO
The oscillator Frequency and Dry/Wet parameters can be modulated with the LFO—and
the envelope follower (see Use the Logic Pro Ringshifter envelope follower). The oscillator
frequency even allows modulation through the 0 Hz point, thus changing the oscillation
direction. The LFO produces continuous, cycled control signals.
Ringshifter LFO parameters
• Power button: Turn the LFO on or off. When it is turned on, you can access the
following parameters.
• Symmetry/Smooth sliders and fields: Change the shape of the LFO waveform.
• Waveform display: Shows changes to the LFO waveform shape.
• Rate knob and field: Set the waveform cycle speed of the LFO.
• Sync button: Synchronize the LFO rate with the project tempo, using musical
note values.
