Kronos Synth has some advanced ADSR modeling features to tailor your sound.
Click here for the Kronos manual.
EGs (Envelope Generators)
The modeling section is divided into three parts: Level, Time, and Curve. All of these three components are defining a single curve, so when adjusting your sound, it is important that you check all three of them.
Also, due to these advanced options, it is possible to create an inverted ADSR curve shape, that is, an upside-down ADSR curve shape.
Level (In order of sequence):
- Start (0): Initial level at time 0
- Attack (A): Level to change to following the start level
- Break (B): Level to change to just before the sustain level
- Sustain (S): Level to sustain before the key is released
- Attack: The length of time between the start level and the attack level.
- Decay: The length of time between the attack level and the break level.
- Slope: The length of time between the break level and the beginning of the sustain level
- Release: The length of time between the end of sustain level and the release falloff
Note: Take note that sustain time is not included as it is dependent on how long you hold the key. The length of sustain ends upon release of the key.
I can't find detailed information on the curvatures available, but it appears that 0 is a linear curve and I am guessing that it gradually accentuates the S curve as the numbers get higher.

Final Note: In Kronos, the levels and times are defined by values 00 ~ 99, which most likely are percentages of some given voltage and a time frame (ms).
