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 (which for the Pitch EG is always
0). Once it reaches the Sustain, 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 the Release level.
Level
Each of the four levels can be either positive or negative.
Positive levels will make the pitch (or other AMS destina‐
tion) go up from its programmed value; negative levels will
make it go down.
Note that, unlike the Filter and Amp EGs, the Pitch EG's
Sustain Level is always 0.
Start
This sets the initial EG level at note‐on.
Attack
This sets the level at the end of the Attack time.
32
Break
Break, short for Break Point, sets the level at the end of the
Decay time.
Release
This sets the level at the end of the Release time.
Curve
For the sake of simplicity, most of the diagrams in this man‐
ual 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 PS60 goes a step further than vintage synths,
[00...99]
however, and lets you control the amount of curvature sepa‐
rately for each of the four envelope segments.

[00...99]
Curve = 0 (Linear)
When you change the curvature, the EG times remain the
[00...99]
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 suit‐
able 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
[–99...+99]
This sets the curvature of the Attack segment ‐ the transition
from the Start level to the Attack level.
[–99...+99]
Decay
This sets the curvature of the Decay segment ‐ the transition
from the Attack level to the Break level.
