NORM 2
A
NORM 2 envelope is very similar to a NORM 1. The main difference is that a NORM 2
envelope jumps to the Release 2 stage (instead of the Release 1 stage in NORM 1) if the
key is let go before the Sustain stage is reached.
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. (This is the same as NORM1 mode.) 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 2 and continue through to the end of the
envelope. See
EXAMPLE 2b (Note Off during ATTACK) and 3b (Note
Off during the
D1TIME).
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 2 stage, at the current level, and proceed
to 0 according to the its time setting.
See
EXAMPLE 2a (Note Off during ATTACK) and 3a (Note Off during
D1TIME).
NORM 2, EXAMPLE 1
This is a NORM 2 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.
