EG (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. SENS I-
TIVITY (AMP LITU DE) is used to set the sensitivity
(refer to page 1 3.)
Applying EG BIAS to a modulator results in brilliance
effects, while applied to a carrier it results in volume
variation effects. In 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
GENERAT ION section on page 9.
2. BREATH CONTROL
The LFO modulation effect programmed can be contro ll ed
using an optional BC1 breath controller. The effect is
controlled by blowing into the BC l mouthpiece. The
effect will not be audible unless breath is applied to the
controller.
Controls the effects according force
