A NDROMEDA A6 R EFERENCE M ANUAL 145
NORM 1
A
NORM 1 envelope will proceed through its cycle to the Sustain stage as long as a
key is being held down (Note On). The Release 1 stage starts when the key is let go
(Note Off). But if the key is let go before the Sustain stage is reached, the envelope
“jumps” to the Release 1 stage. Also, if the key is let go then immediately played
again, the envelope will resume from its current level.
Start: The envelope is started by the beginning of a Note On event.
Progress: During the Note On, the envelope proceeds normally through Delay,
Attack, Decay 1, and Decay 2 stages to the Sustain stage.
Sustain: 1. If the Note On is held until the Sustain stage is reached, the Note
On or a Sustain Pedal On will hold the envelope at the Sustain level
until a Key Off and a Sustain Pedal off occur. The envelope will
then proceed to Release 1 and continue through to the end of the
envelope. See
EXAMPLE 1 .
2. If the Note Off occurs before the Sustain stage is reached, a Sustain
Pedal On will “jump” and hold the envelope in the Sustain stage at
the current level until a Sustain Pedal Off occurs. The envelope will
then proceed to Release 1 and continue through to the end of the
envelope. See
EXAMPLE 2b .
Key Release: 1. If a Note Off event (assuming the Sustain Pedal is off) occurs while
the envelope is in the Sustain stage, the envelope will proceed to
Release 1 stage and progress normally through the envelope to
the end. See
EXAMPLE 1 again.
2. If a Note Off event (assuming Sustain Pedal is off) occurs before
the envelope reaches the Sustain stage, the envelope will jump
immediately to the Release 1 stage, at the current level, and proceed
to the Release 2 level according to the time setting of the Release 1
stage. When the Release 2 stage is reached the envelope will
proceed normally through to the end. See EXAMPLE 2a .
NORM 1, EXAMPLE 1
This is a NORM 1 envelope with the
Note Off occurring after the SUSTAIN
stage was reached.
Note that a Sustain Pedal On will also
hold the envelope at the SUSTAIN level.
When a Note Off or Sustain Pedal Off
occurs, the envelope will proceed into
the RELEASE 1 stage.
