 Dry slider and field: Sets the amount of dry (non-effected) signal.
 Wet slider and field: Sets the amount of wet (effected) signal.
Using the SubBass
Unlike a pitch shifter, the waveform of the signal generated by the SubBass is not
based on the waveform of the input signal, but is sinusoidal (it uses a sine wave). Given
that pure sine waves rarely sit well in complex arrangements, you can control the
amount of (and balance between) the generated and original signals using the Dry and
Wet sliders.
You define the two frequency bands (which the SubBass uses to generate tones) with
the High and Low parameters. High Center and Low Center define the center frequency
of each band, and High Bandwidth and Low Bandwidth define the bandwidth of each
band.
The High Ratio and Low Ratio knobs define the amount that the generated signal is
transposed for each band. This is expressed as a ratio of the original signal. As an
example; Ratio = 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 avoid unwanted
intermodulations. Set High Center a fifth higher than Low Center, which means 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 (Ratio = 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 the SubBass, and compare the extreme low frequency
content of your mixes with other productions. It is very easy to go overboard with it.
