Attack Knob; Decay Knob; Sustain Knob; Release Knob - Clavia Nord Wave User Manual

the attack phase is the time it takes for the sound to go
from zero to full amplitude after a key has been pressed.
•
A very short attack time could produce a click in
the beginning of the sound. To eliminate this, just
increase the attack time slightly.
When the attack phase is finished (and you haven't
released the key), the decay phase takes over. during the
decay phase, the sound decreases in level, and continues
to do so until it reaches the Sustain level. With a decay set-
ting of zero the Sustain Level will be reached instantly after
the attack phase of the envelope is completed.
•
With the Sustain Level set to the maximum, operating
the decAy knob will have no effect.
the sustain is the level the sound will reach after the decay
phase is finished. once this has happened, the sound will
stay steady at this level until the key is released.
the Sustain parameter is used to set a level, while at-
•
tack, decay and release parameters are all used to set
times.

the release phase is the time it will take for the sound to
decay from the envelopes current level to silence after you
have released the key. the release phase may start any-
where during the envelopes phases, it will begin as son as
a key is released.
•
A very short release time could produce a click in the
end of the sound. This is a normal physical phenom-
enon. To eliminate a click, just increase the release
time slightly.

AttAck knob

the AttAck knob sets the time interval for the attack
phase of the envelope. this is time it will take for the sound
to go from zero to the full amplitude after a key has been
pressed.
range: 0.5 ms to 45 s

decAy knob

the decAy knob sets the time interval for the decay phase
of the envelope. When the attack phase is finished (and
you haven't released the key), the decay takes over. during
the decay phase, the amplitude of the sound decreases,
and continues to do so until it reaches the Sustain level.
range: 0.5 ms to 45 s

SuStAiN knob

Use the SuStAiN knob to set the level of the Sustain phase
of the Envelope. this is the level the sound will reach after
the envelope phase has been completed. once this has
happened, the sound will stay at this level until the key is
released. With a setting of zero the amplitude will reach
zero after the decay part of the envelope.
range: 0.0 to 10.0

releASe knob

Use the releASe knob to set the time interval for the re-
lease phase of the envelope. this is how long it should take
for the sound to decay to silence after you have released
the key. With a setting of zero the envelope will instantly
reach zero when the keys are released.
range: 3.0 ms to 45 s
