3-2: Throat Formant Amount Key Scalling
Throat formant amount key scaling produces natural throat formant variations across
the range of the keyboard by allowing different amount 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 throat formant key scaling page without
having to return to the main parameter page.
● Amount
≤
-64 … 63.
The “
Amount
” parameter is linked to the main throat formant “
Amount
” param-
eter, and determines the amount of effect the throat formant sound has on the air velocity
within the instrument. Positive values increase the air velocity, thereby increasing the
throat formant effect. Minus values decrease the air velocity, producing a more subtle
throat formant effect.
This value also determines the main amount value on which all key-scaled variations are
based (indicated by a dotted line on the graph).
● Breakpoint 1 … 4 Key
≤
C-2 … G8.
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.
● Breakpoint 1 … 4 Offset
≤
-64 … 63.
Set the amount offset for each of the breakpoints defined by the breakpoint key
parameters, above. Negative values reduce the amount, and positive values increase the
amount at the corresponding breakpoint. No matter what offset value is chosen, the actual
amount will never exceed its minimum or maximum absolute value. When different
offset values are applied to adjacent breakpoints, the amount varies smoothly between the
breakpoints.
