SOUND

●

 FILTER

Filter is a processor that changes the timbre or tone of a sound by either blocking 

or passing a specific frequency range. The parameters below determine the overall 

timbre of the sound by boosting or cutting a certain frequency range. In addition to 

making the sound either brighter or mellower, Filter can be used to produce elec-

tronic, synthesizer-like effects.

●

 EG

The EG (Envelope Generator) settings determine how the level of the sound 

changes in time. This lets you reproduce many sound characteristics of natural 

acoustic instruments—such as the quick attack and decay of percussion sounds, or 

the long release of a sustained piano tone.

BRIGHTNESS

Determines the cutoff frequency or effective frequency range of the 

filter (see diagram). Higher values result in a brighter sound.

HARMONIC CONTENT

Determines the emphasis given to the cutoff frequency (resonance), 

set in BRIGHTNESS above (see diagram). Higher values result in a 

more pronounced effect.

ATTACK

Determines how quickly the sound reaches its maximum level after 

the key is played. The lower the value, the quicker the attack.

DECAY

Determines how quickly the sound reaches its sustain level (a 

slightly lower level than maximum). The lower the value, the 

quicker the decay.

RELEASE

Determines how quickly the sound decays to silence after the key is 

released. The lower the value, the quicker the decay.

Volume

Cutoff frequency

These frequencies are 

“passed” by the filter.
