1-2: Harmonic Enhancer Overdrive Key Scaling - Yamaha VL1 Owner's Manual

Further, the higher
breakpoint applies to the
specified note while the
lower one actually applies
to the next note to its left.
If more than two break-
points are set to the same
note, only the lowest and
highest of these will
function as ends of the
corresponding key scaling
segments while the rest
are ignored.
Feature Reference
Breakpoint 1 & 2 Offset
≤
-64 ... 63.
Set the amount of cutoff frequency offset for each of the breakpoints defined by the
breakpoint key parameters, above. Negative values lower the cutoff frequency, and
positive values raise the cutoff frequency at the corresponding breakpoint. No matter
what offset value is chosen, the actual cutoff frequency will never exceed its minimum or
maximum absolute value. When different offset values are applied to adjacent break-
points, the cutoff frequency varies smoothly between the breakpoints.

1-2: Harmonic Enhancer Overdrive Key Scaling

Harmonic Enhancer overdrive key scaling produces natural timbral variations across
the range of the keyboard by allowing different overdrive offset values to be applied to
each of two breakpoints set at appropriate keys. Key scaling can be applied independently
to the carrier and modulator overdrive parameters.
Carrier Parameters
Modulator Parameters
• Separate key scaling parameter pages are provided for the carrier and modula-
tor overdrive parameters. The appropriate key scaling page will be selected
when you press ¶ ("KSC") from the main carrier or modulator parameter
page.
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.
CrrOvr, ModOvr
≤
0.063 ... 15.31 kHz.
The "CrrOvr" and "ModOvr" parameters are linked to the main harmonic en-
hancer "Over Drive" parameters, and set the amount of distortion produced by the
carrier or modulator. This value also determines the main overdrive level on which all
key-scaled variations are based (indicated by a dotted line on the graph).
