EG (Envelope Generator)
For the most part, each sound changes over time in a distinct way, such as volume. For example, when
you play a note on a piano, the note begins at the maximum volume, and gradually diminishes. When
you release your finger from the key, the sound disappears quickly with a brief decay. Volume curves
such as this are an important aspect of how we identify the sound of a specific instrument. This type
of change also occurs in the tone and pitch, as well as in the volume. On a synthesizer, this type of
change is produced by an EG. The microKORG2 has dedicated EGs for the filter and for the amp.
These EGs can also be used as virtual patch sources, so you are free to use them to vary the pitch or
numerous other aspects of the sound.
Some example settings are shown below.

FILTER EG
Here you can make settings for the filter EG, which applies time-variant change to the tone.
Configure these filter EG settings to make the tonal character of the sound change over time.
The EG Intensity parameter controls how much the filter EG is applied.
Create the desired sound curve by adjusting the ADSR parameters: Attack [1], Decay [2], Sustain [3]
and Release [4].
For details on how the EG (envelope generator) works, refer to the previously listed information.
1. Attack [0...127] (CC#85)
Sets the time from note-on (when the key is pressed) until the attack level (maximum value of the
envelope) is reached.
2. Decay [0...127] (CC#86)
Sets the time from when the attack level is reached until the sustain level (SUSTAIN) is reached.
3. Sustain [0...127] (CC#87)
Sets the cutoff frequency that’s maintained after the decay time has elapsed until you release the
key.
4. Release [0...127] (CC#88)
Sets the time it takes from note-off (when the key is released) until the level reaches 0.
