Break
Break, short for Break Point, sets the level at the end of the
Decay time.
Sustain
This sets the level at the end of the Slope time. Once it
reaches the Sustain level, the EG will stay there until note‐off
(unless it is reset via AMS).
Time
Higher values mean longer times, as shown below.
EG Value Actual Time
10 10 ms
20 44 ms
30 104 ms
40 224 ms
50 464 ms
60 944 ms
70 1.8 seconds
80 3.8 seconds
90 10.9 seconds
99 87.3 seconds
Attack
This sets how long the EG takes to move from the Start level
to the Attack level.
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
For the sake of simplicity, most of the diagrams in this
manual show envelopes as being made out of straight lines.
In actuality, though, envelopes are more likely to be made
out of curves.
In other words, each segment's level will change quickly at
first, and then slow down as it approaches the next point.
This tends to sound better than straight, linear segments.
Classic analog synth envelopes made these curved shapes
naturally. The KROME 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.

Different curve settings for up and down
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.
[00...99]
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
[00...99]
from the Break level to the Sustain level.
Release
This sets the curvature of the Release segment ‐ the
[00...99]
transition from the Sustain level to the Release level.
4–3c: EG Level/Time Modulation
Level
[00...99]
These settings let you use any 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.
Once an EG segment begins, it can't be modulat-
ed
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 more information, please see "Once an EG segment
begins, it can't be modulated" on page 33.
