SubBass use tips in Logic Pro for iPad
Unlike a pitch shifter, SubBass generates a waveform that is not based on the waveform of the input signal; instead it uses a sine wave. Given that pure sine waves rarely work well in complex arrangements, make sure to use the Wet and Dry sliders to control the amount of—and balance between—the generated and original signals.
Use the High parameters and the Low parameters to define the two frequency bands that SubBass uses to generate tones. Center High and Center Low define the center frequency of each band, and Bandwidth High and Bandwidth Low define the width of each frequency band.
The Ratio High and Ratio Low knobs define the transposition amount for the generated signal in each band. This is expressed as a ratio of the original signal. For example, a Ratio value of 2 transposes the signal down one octave.
Important: Within each frequency band, the filtered signal should have a reasonably stable pitch in order to be analyzed correctly.
In general, narrow bandwidths produce the best results, because they minimize frequency intermodulations which can lead to unpleasant artifacts. Set the Center High knob value a fifth higher than Center Low, a factor of 1.5 for the center frequency.
Derive the sub-bass to be synthesized from the existing bass portion of the signal, and transpose by one octave in both bands, using a Ratio of 2. Do not overdrive the process or you will introduce distortion. If you hear frequency gaps, move one or both Center frequency knobs, or widen the Bandwidth of one or both frequency ranges a little.
Tip: Be prudent when using SubBass, and compare the extreme low frequency content of your mixes with other productions. It is very easy to over-enhance the low end of some tracks, resulting in an unbalanced mix.
