Note: Sibilance is
reduced only at the
Studio Vocalist EX's
pitch recognition cir-
cuitry and not in the
audio path. The fre-
quency response of
the input voice is
not affected.

Ess Sensitivity
The Ess Sensitivity adjustment allows you to decrease the amount of
sibilant energy (i.e. "ess", "tee" and "ch" sounds) presented to the input
of the Studio Vocalist EX's pitch recognition circuitry. An increase in the
Ess Sensitivity parameter increases the Studio Vocalist EX's ability to
"ignore" sibilant sounds, thereby minimizing the chance of pitch tracking
errors. This setting can need to be adjusted to accommodate different
singers. It is easily modified while the singer sings.
To adjust the Ess Sensitivity:
1. Press the Utilities button from any mode; this presents the
UTILITIES main menu.
2. Press the Audio softkey.
3. Use the Data Wheel to increase or decrease the Ess Sensitivity as desired.
4. Press the Utilities button once again to exit; this will return you to
the mode from which you entered.
Bass Rejection
The Bass Rejection Threshold control is used to increase the Studio
Vocalist EX's immunity to pitch tracking errors caused by low frequency
noise at the input. Increasing the Bass Rejection Threshold is useful for
filtering out wind, background, or microphone handling noise. Once
again, the frequency response of the audio path is not affected.
To adjust the Bass Rejection Threshold:
1. Press the Utilities button from any mode; this presents the
UTILITIES main menu.
2. Press the Audio softkey.
3. Press the Right Arrow button.
4. Use the Data Wheel to increase or decrease the Bass Rejection
Threshold as desired.
5. Press the Utilities button once again to exit; this will return you to
the mode from which you entered.
Harmony Gating Threshold
The Harmony Gating Threshold allows you to set the level which the
input voice must exceed in order for the harmonies to turn on. This can
be a handy adjustment for live performance, where the sound from other
instruments can interfere with the Studio Vocalist EX's pitch recognition.
For example, if the Harmony Gating Threshold is set at -20 dB, then any
background or stage noise at a level less than -20 dB, according to the
Studio Vocalist EX's front-panel input level meters, will not cause the
harmonies to be enabled; the dry signal is output normally. Once the
input level exceeds -20 dB (i.e. the singer sings into the microphone), the
Studio Vocalist EX will lock on to the voice and the harmonies will be
