Vcf Cutoff; Feg Depth - Yamaha AN1x Owner's Manual

VCF Cutoff

The VCF Cutoff setting determines the cutoff frequency
of the VCF. The value set here is related to the assigned
VCF Type in the MIX/VCF parameter group (see page
67).
For example, when the filter type is set to Low Pass
Filter, the lower frequencies are passed while higher
frequencies are cut off. Turning the knob to the right
increases the VCF Cutoff frequency, as shown in the
graph below.

VCF Type = Low Pass Filter
Settings: 0 ~ 127
Resonance
The Resonance setting determines the amount of
resonance boost, or emphasis of harmonics near the
cutoff frequency. Turning the knob to the right produces
a higher resonant peak (producing sharper high tones),
while turning it to the left produces a relatively flat
response. A setting of "0" applies no resonance.

FEG Depth

The FEG Depth setting determines the range of
movement of the cutoff frequency. Turning the knob to
the right increases the FEG Depth. Negative values
reverse the shape of the envelope. When not using the
FEG, set the value to "0".

Vel Sens
(Velocity Sensitivity)
The Velocity Sensitivity setting determines how the VCF
responds to velocity, or keyboard playing strength.
Turning the knob to the right increases dynamic range
according to how hard you strike the keys, and turning
it to the left produces the opposite effect (i.e., a lighter
touch increases the dynamic range and a heavier touch
decreases it). A setting of "0" creates no change in
dynamic range by playing strength.
Settings: -64 ~ 0 ~ +63
