Chapter 8 Modulation 103
Delay
The effect signal is routed through a delay, following the oscillator. The Level control
sets the level of the delay added to the ring modulated or frequency shifted signal.
Note: A Level value of 0 passes the effect signal directly to the output (bypass).
The Time control sets the delay value from 0 to 2,000 milliseconds. Activation of the
Sync button synchronizes the delay to your Logic song tempo, in musical note values.
Output
The RingShifter offers a feedback loop, which operates independently of the delay
section, by routing the output of the RingShifter back into its input. Feedback gives the
RingShifter sound an additional edge, and is useful for a variety of special effects. In
combination with a slow oscillator sweep, it produces a rich phasing sound. Comb
filtering effects are created using high Feedback settings with a short delay time
(< 10 ms). Using longer delay times in combination with Feedback creates spiralling
and continuously rising and falling frequency shift effects.
The Stereo Width rotary control determines the breadth of the effect signal in the ste-
reo field.
Note: Stereo Width only affects the effect signal of the RingShifter, not the dry input
signal.
The Dry/Wet rotary control sets the mix ratio of the dry input signal and the wet effect
signal. If required, the Dry/Wet mix can also be modulated with an envelope follower
and LFO. The modulation depth for the envelope follower and LFO is set indepen-
dently with their bipolar sliders
Modulation Sources
The Oscillator Frequency and Dry/Wet mix ratio parameters can be modulated via the
internal Envelope Follower and 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, and uses
this to create a continuously changing control signal—a dynamic volume envelope of
the input signal. This “control signal” can be used for modulation purposes. The Power
button turns the Envelope Follower on or off. The Sens(itivity) slider determines how
responsive the Envelope Follower is to the input signal. At lower settings, the Envelope
Follower will only react to the most dominant signal peaks. At higher settings, the
Envelope Follower will track the signal more closely, but may react less dynamically. Try
to find a suitable median (compromise) setting for the input signal. The response time
of the Envelope Follower is set with the Attack slider. Decay controls the time it takes
the Envelope Follower to return from a higher to a lower value.
