• Amplitude & Filter Envelope Release Time
• Settings: -64 … +63

Sets the release time of the amplitude & filter
envelope generator. “Release time” refers to the
length of time it takes for the envelope to fall to
“zero” level after the note has been released.
Positive values produce a slower release while
negative values produce a faster release.

• Amplitude Level Scaling Breakpoint
• Settings: C-2 … G8

Amplitude level “scaling” ( or “key scaling”)
produces natural level variations across the VL70-
m note range by allowing an increasing or decreas-
ing amplitude “depth” curve to be applied above or
below a specified “breakpoint” note. The
“AmpLvlScBP” parameter specifies the breakpoint
note.

 (VOICE mode only)

• Amplitude Level Scaling Depth
• Settings: -64 … +63

This parameter specifies the amount of amplitude
level key scaling to be applied above or below the
breakpoint note specified by the “AmpLvlScBP”
parameter, above. A setting of “+00” produces no
key scaling. Positive values apply scaling to notes
below the breakpoint (i.e. on a keyboard, notes to
the left of the breakpoint), producing a gradual

lowering of amplitude level down the scale.
Negative values apply scaling to notes above the
breakpoint (i.e. on a keyboard, notes to the right of
the breakpoint), producing a gradual lowering of
amplitude level up the scale. Higher positive or
negative values produce a greater variation in the
amplitude level.

• Pitch & Embouchure Envelope Initial Level
• Settings: -64 … +63

Sets the initial level of the pitch & embouchure
envelope generator. A setting of “+00” starts the
pitch envelope at normal pitch. Positive values
raise the initial pitch while negative values lower
the initial pitch in relation to normal pitch.
