The

(OEGs).

providing individual articulation (at-
tack, decay, etc.)
for
each note. The remaining OEG (DEG
3) dynamically changes the VCF Cutoff and Noise level.
All Digital Envelope Generators use en advanced

,
design. In addition to the normal
Altack.
Decay, Sustain
and Release functions, they include
EAEAK
POINT and
SLOPE functions. which control an extra envelope Stage
that can create either a second attack or a second decay.
These newly designed
OEGs
provide. highly improved
percussive and instrumental sounds and many new
special effects.
In WHOLE Mode. the
8
OEGs
that provide
DC0
articulation
(Volume Envelopes) are all controlled by the OEG 1
parameters
(5

),
so
that all
notes
are articulated in
a similar way. In
this.mode
the
DEG 2 parameters have no
effect (and appear blank if you try to access them).
In DOUBLE Mode, two
OCOs
and two
DEGs
are assigned
to each note. Each DEG (and OCO) may be programmed
separately, creating a wide range of complex, dynamic
sounds.
DC0
1 is controlled by OEG 1
