3-2: Vibrato Attack Rate Key Scaling

Vibrato attack rate key scaling produces natural attack rate variations across the
range of the keyboard by allowing different rate offset values to be applied to each of two
breakpoints set at appropriate keys.
The § and ¶ buttons ("Bpag" and "Fpag") can be used to go directly
•
backward or forward to the next Vibrato key scaling page without having to
return to the main parameter page.
AtRate
The "AtRate" parameter is linked to the main Vibrato "Attack Rate" param-
eter, and has the same effect. This value also determines the main attack rate on which all
key-scaled variations are based (indicated by a dotted line on the graph).
Breakpoint 1 & 2 Key
Allows two separate key scaling breakpoints to be set at any notes between C-2 and
G8. You can position the cursor at the appropriate breakpoint key parameter and use any
of the normal data entry procedures, or use the keyboard. To use the keyboard for break-
point entry, position the cursor at the appropriate breakpoint key parameter, press the •
button ("Kbd"), and then press the key at which you want to set the breakpoint while
"Kbd" appears in inverse characters.
No breakpoint can be set to a key lower than the breakpoint to its left.
Breakpoint 1 & 2 Offset
Set the amount of attack rate offset for each of the breakpoints defined by the
breakpoint key parameters, above. Negative values reduce the attack rate, and positive
values increase the attack rate at the corresponding breakpoint. No matter what offset
value is chosen, the actual attack rate will never exceed its minimum or maximum
absolute value. When different offset values are applied to adjacent breakpoints, the
attack rate varies smoothly between the breakpoints.
