You can change the expression of the sound in real time by operating the [EG FILTER] knob while playing phrases.
This list explains the control types of each EG and Filter.
EG (Envelope Generator)
EG allows you to determine how the level of the sound changes in time. This lets you to reproduce a variety of sound
characteristics of natural acoustic instruments—such as the quick attack and decay of percussion sounds, or the long
release of sustained piano sound. The YC61 controls the following three characteristics with a single knob.
How these three characteristics change with a single knob operation is referred to as EG control type. The YC61 has 11
types. The type can be set using the [EXIT] [EG FILTER] knob operation, or from the “EG Control” (page 43).
Graphs below show how the Attack, Decay, and Release change when the knob is turned from the center (= 64) to the left
and right in each type.
EG/Filter Control Type List
Attack Determines the time which the sound reaches its maximum
level after the key is played. The lower the value, the quicker
the attack.
Decay Determines the time it takes for the sound reaches its sustain
level (a slightly lower level than maximum). The lower the
value, the quicker the decay.
Release Determines the time it takes for the sound decays to silence
after the key is released. The lower the value, the quicker the
release.

Atk&Dcy&Rls A/B
Types which the Attack, Decay, and Release are
all changed by the knob.
Attack/Decay/Release
Types which only one of Attack, Decay, and Release is
changed by the knob.
Atk&Rls A/B/Minus
Types which the Attack and Release are changed by the knob. “B” is suitable for
making pad sounds. “Minus” enables creation of unusual sounds, since turning
the knob clockwise reduces the release time.
Dcy&Rls
A type which the Decay and Release
are changed by knob operation.
Atk&Dcy A/B
Types which the Attack and Decay are changed by the knob.
“B” has less change.
