EXi: STR-1 Plucked String
Attack
This sets how long the EG takes to move from the Start level
to the Attack level.
The minimum attack time is 2/3 of a millisecond–as fast as
the most punchy of classic analog synths.
For the fastest possible attack time, you can set the Start
level to +99; in this case, the EG will start instantaneously at
its maximum value.
Decay
This sets the time it takes to move from the Attack level to
the Break level.
Slope
This sets how long the EG takes to move from the Break
level to the Sustain level. Once it reaches the Sustain level,
the EG will stay there until note-off (unless it is reset via
AMS).
Release
This sets how long it takes the EG to move from the Sustain
level to silence.
Curve
Classic analog synth envelopes created curved shapes
naturally. The NAUTILUS goes a step further than vintage
synths, however, and lets you control the amount of
curvature separately for each of the four envelope segments.
When you change the curvature, the EG times remain the
same. However, greater curvature will tend to sound faster,
because the value changes more quickly at the beginning.
You may find that different amounts of curvature are suitable
for segments which go up and segments which go down.
For instance, a curve of 3 is a good default setting for
upward segments, such as Attack. On the other hand, a curve
of 6 or more is good for downward segments, such as Decay
and Release.
Attack
This sets the curvature of the Attack segment - the transition
from the Start level to the Attack level.
Decay
This sets the curvature of the Decay segment - the transition
from the Attack level to the Break level.
Slope
This sets the curvature of the Slope segment - the transition
from the Break level to the Sustain level.
Release
This sets the curvature of the Release segment - the
transition from the Sustain level to the Release level.
6–3c: Level Modulation
These settings let you use an AMS source to control the
Level parameters of the EG. The Start, Attack, and Break
levels share a single AMS source, but can each have
different modulation intensities.

[0 (Linear), 1...9, 10 (Exp/Log)]
[0 (Linear), 1...9, 10 (Exp/Log)]
Note: Once the EG has started a segment between two
points, that segment can no longer be modulated. For
instance, if the EG is in the middle of the Decay time, you
can no longer modulate either the Decay time or the Break
level.
This also means that modulating the Start level, Attack level,
or Attack time will not affect notes that are already
sounding, unless the EG is then reset via AMS.
AMS
This selects an AMS source to control the EG's Level
parameters.
For a list of AMS sources, see "Alternate Modulation Source
(AMS) List" on page 901.
Start
This controls the depth and direction of the AMS modulation
for the Start level.
Attack
This controls the depth and direction of the AMS modulation
for the Attack level.
Break
This controls the depth and direction of the AMS modulation
for the Break level.
6–3d: Time Modulation
These settings let you use three different AMS sources to
control the Time parameters of the EG. For each of the three
AMS sources, the Attack, Decay, Slope, and Release times
each have their own modulation intensities.
AMS1
Selects the first AMS source to control the EG's Time
parameters. Velocity and Keyboard Track can both be useful
here, for instance.
For a list of AMS sources, see "Alternate Modulation Source
(AMS) List" on page 901.
Attack
This controls the depth and direction of the AMS modulation
for the Attack time.
When the AMS source is at its maximum value–for instance,
when Velocity is at 127–a setting of +8 will make the
segment time almost twice as long, and a setting of -8 will
cut the segment time almost in half.
Decay
This controls the depth and direction of the AMS modulation
for the Decay time.
Slope
This controls the depth and direction of the AMS modulation
for the Slope time.
Release
This controls the depth and direction of the AMS modulation
for the Release time.
