VELOCITY FILT 1 ENV AMT

Determines the intensity of the VELOCITY control for the modulation of Filter 1’s cutoff frequency by the
filter envelope.

VELOCITY FILT 2 ENV AMT

Determines the intensity of the VELOCITY control for the modulation of Filter 2’s cutoff frequency by the
filter envelope.

VELOCITY RESONANCE 1

Determines the intensity of the VELOCITY control for the resonance of Filter 1.

VELOCITY RESONANCE 2

Determines the intensity of the VELOCITY control for the resonance of Filter 2.

VELOCITY VOLUME

Determines the intensity of the VELOCITY control for the volume.

VELOCITY PANORAMA

Determines the intensity of the VELOCITY control for the Panorama position.
