Time
Higher values mean longer times. For a chart showing
equivalents in milliseconds, please see “Time” on
page 79.
Attack
[00…99]
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
[00…99]
This sets the time it takes to move from the Attack level
to the Break level.
Slope
[00…99]
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
[00…99]
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 OASYS 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
[0 (Linear), 1…9, 10 (Exp/Log)]
This sets the curvature of the Attack segment - the
transition from the Start level to the Attack level.
Decay
[0 (Linear), 1…9, 10 (Exp/Log)]
This sets the curvature of the Decay segment - the
transition from the Attack level to the Break level.
Slope
[0 (Linear), 1…9, 10 (Exp/Log)]
This sets the curvature of the Slope segment - the
transition from the Break level to the Sustain level.
Release
[0 (Linear), 1…9, 10 (Exp/Log)]
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.
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
[List of AMS Sources]
This selects an AMS source to control the EG’s Level
parameters.
For a list of AMS sources, see “AMS (Alternate
Modulation Source) List” on page 967.
Start
[–99…+99]
This controls the depth and direction of the AMS
modulation for the Start level.
Attack
[–99…+99]
This controls the depth and direction of the AMS
modulation for the Attack level.
Break
[–99…+99]
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
[List of AMS Sources]
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 “AMS (Alternate
Modulation Source) List” on page 967.
Attack
[–99…+99]
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
[–99…+99]
This controls the depth and direction of the AMS
modulation for the Decay time.
Slope
[–99…+99]
This controls the depth and direction of the AMS
modulation for the Slope time.
