A Quick Tour of UniQuest For EWI 4000s

22 of 44 UniQuest for EWI 4000s

BREATH MOD

• Range is 0 to 100%. This control allows you to change the filter cutoff frequency

with your breath pressure. Higher values apply more modulation to the cutoff

frequency.

BREATH CURVE

• Range is -50% to +50%. This parameter sets the mapping of breath pressure to

cutoff frequency for this filter. 0% means a linear 1:1 mapping as follows:

Filter LFO Parameters

Not only does each filter have a dedicated LFO that can be used to modulate its cut-

off frequency, this LFO can be controlled in real-time by your breath pressure for a

variety of exciting performance effects.

LFO FREQUENCY

• Range is 0 to 100%. This control changes the LFO rate.

LFO DEPTH

• Range is 0 to 100%. This control changes the amount of LFO modulation that is

applied to the cutoff frequency. Higher values result in more modulation.

LFO BREATH

• Range is -50% to 50%. This control modulates the LFO DEPTH, allowing your

breath pressure to control how much LFO modulation is applied to the filter’s

cutoff frequency. Positive values cause greater breath pressures to result in

greater amounts of LFO modulation, while negative amounts of this control

cause greater breath pressures to result in lesser amounts of LFO modulation.

Note that since negative values of LFO BREATH reduce the amount of LFO Modu-

lation, LFO DEPTH must be set to 100% to achieve the curve shown in the illustra-

tion above.
