1-4: Harmonic Enhancer Modulator Index Key Scaling - Yamaha VL-1 Feature Reference

Feature Reference
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 ... 4 Offset
Set the amount of level offset for each of the breakpoints defined by the breakpoint
key parameters, above. Negative values reduce the carrier level, and positive values
increase the carie level at the corresponding breakpoint. No matter what offset value is
chosen, the actual carrier level will never exceed its minimum or maximum absolute
value. When different offset values are applied to adjacent breakpoints, the carrier level
varies smoothly between the breakpoints.

1-4: Harmonic Enhancer Modulator Index Key Scaling

Harmonic Enhancer modulator index key scaling produces natural timbral variations
across the range of the keyboard by allowing different modulator index offset values to
be applied to each of four breakpoints set at appropriate keys.
The § and ¶ buttons ("Bpag" and "Fpag") can be used to go directly
•
backward or forward to the next harmonic enhancer key scaling page without
having to return to the main parameter page.
ModIdx
The "ModIdx" parameter is linked to the main harmonic enhancer modulator
"Index" parameter, and sets the amount of modulation applied to the carrier. This value
also determines the main modulator index on which all key-scaled variations are based
(indicated by a dotted line on the graph).
Breakpoint 1 ... 4 Key
Allows four 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.
