4-1: Growl Speed Key Scaling - Yamaha VL1 Owner's Manual

Feature Reference
Speed
≤
0 ... 127.
Sets the speed of the growl effect. The higher the value the faster the growl.
Randomness
≤
0 ... 10.
The "Randomness" parameter can be used to introduce random variations in the
speed of the growl effect. The higher the value the greater the random variation.

4-1: Growl Speed Key Scaling

Growl speed key scaling produces natural growl speed variations across the range of
the keyboard by allowing different speed offset values to be applied to each of two
breakpoints set at appropriate keys.
Speed
≤
0 ... 127.
The "Speed" parameter is linked to the main Growl "Speed" parameter, and has
the same effect. This value also determines the main speed setting on which all key-
scaled variations are based (indicated by a dotted line on the graph).
Breakpoint 1 & 2 Key
≤
C-2 ... G8.
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
≤
-64 ... 63.
Set the amount of speed offset for each of the breakpoints defined by the breakpoint
key parameters, above. Negative values reduce the growl speed, and positive values
increase the growl speed at the corresponding breakpoint. No matter what offset value is
chosen, the actual speed will never exceed its minimum or maximum absolute value.
When different offset values are applied to adjacent breakpoints, the growl speed varies
smoothly between the breakpoints.
