3-1: Throat Formant Pitch Key Scalling
Throat formant pitch key scaling produces natural throat formant pitch variations
across the range of the keyboard by allowing different pitch offset values to be applied to
each of four breakpoints set at appropriate keys.

Pitch
23.1 Hz ... 48.0 kHz (when "Fixed" and "Intens" ≥ 0).
≤
≤
11.4 Hz ... 24.0 kHz (when "Fixed" and "Intens" < 0).
≤
-2.00oct ... 1.98oct (when "KeyTrack").
The "Pitch" parameter is linked to the main throat formant "Pitch" parameter,
and has the same effect. When the "Pitch Tracking" parameter is set to "Fixed",
this parameter sets the throat formant pitch to a specific frequency. When "Pitch
Tracking" is set to "KeyTrack", however, this parameter determines how much the
throat formant pitch is offset from the pitch of the key played in octave units. In the latter
case negative values offset the throat formant pitch below the pitch of the key played,
while positive values offset the throat formant pitch above that of the key played. This
value also determines the main pitch on which all key-scaled variations are based (indi-
cated 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
≤
-127 ... 127.
Set the amount of pitch offset for each of the breakpoints defined by the breakpoint
key parameters, above. Negative values lower the pitch, and positive values raise the
pitch at the corresponding breakpoint. No matter what offset value is chosen, the actual
pitch will never exceed its minimum or maximum absolute value. When different offset
values are applied to adjacent breakpoints, the pitch varies smoothly between the break-
points.
