Creating and Editing Single Sounds
Page 15
DECAY
This will only affect those sounds which feature decay. Decay
is the effect of something fading away as you hold a key on
the keyboard. A piano sound is a good example of a sound
which has decay. As you hold down the key, the sounds fades
away or decays. Eventually you will hear no sound at all.
An organ sound, on the other hand, has no decay. The level
of the sound remains the same as long as you hold down a
key. The decay function is used to adjust the amount of time
it takes a sound to decay, (in the case of our piano sound
that would be the amount of time it took between when the
sound is at maximum level and the point at which we no
longer hear anything).
Since this function can be used to either increase or decrease
the decay time of the original sound, the original decay time
of the sound can be restored by setting the value to zero.
RELEASE
The release function is used to adjust the amount of time a
sound continues to play after the key has been released.
This release time: increases as the value is increased.
Maximum release times can last for more than twenty or
thirty seconds after a key has been released.
Since this function can be used to either increase or decrease
the release time of the original sound, the original release
time of the sound can be restored by setting the value to zero.
FILTER CUT-OFF
In its simplest form, this is the sounds most important tone
control. Cut-Off is one half of the main filter controls, (the
other being Resonance). Usually these two are used in
combination for powerful manipulation of a sounds tonal
character. As the value is decreased, the filter closes allowing
less of the original sound to pass through. This generally has
the effect of making the sound warmer and less fizzy.
Increasing the value opens the filter, increasing the brilliance
of the sound.
