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

(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

(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.
