Ringshifter oscillator parameters in Logic Pro for iPad
In both frequency shifter modes and Ringmodulation Sine mode, the internal sine wave oscillator is used to modulate the amplitude of the input signal.
In the frequency shifter modes, the Frequency parameter controls the amount of frequency shifting, either up or down, applied to the input signal.
In Ringmodulation Sine mode, the Frequency parameter controls the frequency content, or timbre, of the resulting effect. This timbre can range from subtle tremolo effects to clangorous metallic sounds.
Oscillator parameters
Operating Mode pop-up menu: Choose an operating mode for Ringshifter:
Ringmodulation Sine: Turn on to use the internal sine wave oscillator to modulate the input signal.
Ringmodulation Sidechain: Turn on to modulate the amplitude of the input signal with the audio signal assigned via the side chain input.
The sine wave oscillator is switched off, and the Frequency controls are disabled when Side Chain mode is active.
Frequency Shift Single: Turn on to generate a single, shifted effect signal.
The oscillator Frequency control determines whether the signal is shifted to a positive value on the right side of the Frequency knob or to a negative value on the left side.
Frequency Shift Dual: Turn on to produce one shifted effect signal for each stereo channel—one is shifted up, the other is shifted down.
The oscillator Frequency control determines the shift direction towards the left or the right channel.
Freq Shift Mode buttons: Switch the scaling of the Frequency control.
Exponen(tial): Exponential scaling provides extremely small increments around the 0 point, which is useful for programming slow-moving phasing and tremolo effects.
Linear: Linear scaling is even across the entire control range.
Frequency knob and field: Set the frequency of the sine oscillator.
Oscillator frequency modulation parameters
Env slider and field: Determine the impact of incoming signal levels on the oscillator modulation depth.
LFO slider and field: Determine the amount of oscillator modulation by the LFO.
