ЕС (ENVELOPE GENERATOR) BIAS:
When EG BIAS is ON, volume or brilliance (wow) variation
effects can be added with the controllers by varying the
level of each operator's envelope generator. MOD. SENSI-
TIVITY (AMPLITUDE) is used to set the sensitivity
(refer to page 13.)
Applying EG BIAS to a modulator results in brilliance
effects, while applied to a carrier it results in volume
variation effects. іп some cases, if the carrier sensitivity
is maximum and the controller is set to its minimum, no
sound will be produced.
As for "modulator" and "'carrier"", refer to the FM TONE
GENERATION section on page 9.
2. BREATH CONTROL
The LFO modulation effect programmed can be controlled
using an optional BC1 breath controller. The effect is
controlled by blowing into the ВС1 mouthpiece. The
effect will not be audible unless breath is applied to the
controller.

EDIT RECALL:
This function makes it possible to recall a voice that was
previously being edited or created.
If, for example, the PLAY mode is accidentally or pur-
posely entered while editing, the voice that was being
edited can be recalled with this function.
If the key is pressed, the display shows
"EDIT RECALL?'. Pressing the DATA ENTRY
key then causes the "АНЕ YOU SURE?" display. Verify
by pressing the key again, and the voice previously
being edited will be restored.

VOICE INIT (Voice Initialize):
This function sets up the basic voice data for creating new
voices. Press the[VOICE INIT]key and the display panel
will read "VOICE INIT?" Press the key and the
ОХ9 will respond with "ARE YOU SURE?" Verify by
pressing the key second time. This sets up the basic
voice data and activates the DX9 EDIT mode.
e BATTERY CHECK
A backup battery power supply is built into the DX9 so
that voice data will be maintained even when power to
the instrument is off. The state of the backup system can
be checked by pressing the
key. The operational battery voltage range is from 2.2 volts
to 3.3 volts. If the backup battery voltage drops below 2.2
volts, replacement of the backup system is necessary. The
backup system consists of special batteries which can be
replaced only by a Yamaha dealer. Contact your nearest
Yamaha dealer when replacement becomes necessary.
@ MEMORY PROTECT
MEMORY
PROTECT
The 0Х9% internal MEMORY PROTECTION function will
prevent any accidental erasure of the internal voice data.
You will first have to turn the MEMORY PROTECT OFF
in order to STORE or LOAD the voice data. Also, do not
forget to turn the MEMORY PROTECT function back ON
after storing or loading operation.
