Harmonic Enhancer HPF key scaling produces natural timbral variations across the
range of the keyboard by allowing different cutoff frequency offset values to be applied
to each of two breakpoints set at appropriate keys. Key scaling can be applied independ-
ently to the carrier and modulator high-pass filters.
•
Separate key scaling parameter pages are provided for the carrier and modula-
tor high-pass filters. 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.
● CrrHPF, ModHPF
≤
17.0 Hz … 11.2 kHz.
The “
CrrHPF
” and “
ModHPF
” parameters are linked to the main harmonic en-
hancer “
HPF Cutoff
” parameters, and set the cutoff frequency of the carrier or modu-
lator high-pass filter. Frequency components below the specified frequency are cut off.
This value also determines the main cutoff frequency 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.
1-1: Harmonic Enhancer HPF Key Scaling
■
If two breakpoints are
set to the same note, the
lower one functions as the
end of the key scaling
segment connecting to the
next lowest breakpoint
while the higher one
functions as the end of the
segment connecting to the
next highest breakpoint.
