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.
7–1c: 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.
By using different settings for each of the three levels, you
can cause both subtle and dramatic changes to the EG shape,
as shown below.
EG Level Modulation
Once an EG segment begins, it can’t be
modulated
Once the EG has started a segment between two points, that
segment can no longer be modulated. This includes both the
time of the segment, and the level reached at the end of the
segment.
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.
As another example, let’s say that you’ve assigned the
Common LFO to modulate Break Level. The LFO may be
moving all the time, but the Break Level is only affected by
the LFO’s value at the instant that the Decay segment starts.
After that, the level is fixed.
Finally, 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 “Alternate Modulation Source
(AMS) List” on page 901.
Start [–99…+99]
This controls the depth and direction of the AMS modulation
for the Start level.
For example, if you set the AMS source to Velocity and set
Start to +99, the Start level will increase as you play harder.
If you instead set Start to –99, the Start level will decrease as
you play harder.
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.
7–1d: 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.
EG Time Modulation
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 “Alternate Modulation Source
(AMS) List” on page 901.
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.
For example, if you set the AMS source to Velocity and set
Attack to +99, the Attack time will get much longer at higher
velocities. If you instead set Attack to –99, the Attack time
will get much shorter at higher velocities.
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.
