DECAY (Rats)
Determines the rate at which the envelope contour
falls from the maximum (Attack) level lo the BREAK
POINT level, after the ATrACK phase is completed,
. If BREAK POINT equals
3
:
, the DECAY parameter
has no effect. There needs to be at least a
:
number difference in starting 8 ending Levels for
Rate parameters lo have a” effect (the Attack peak
is always
3
:
.)
The bigger the difference, the longer
the actual lime produced by a given DECAY value.

fix
example. assume DECAY is
jl
:,
with BREAK
POINT
(B.p.)=
3g,
the actual Decay cycle lasts
about 0.5 seconds. With BP.=
?‘p,
it lasts about
1.2 seconds (DECAY=
3
:).
Al BP.=
25,
it lasts
about 3 seconds, and at ZL:. about
5 seconds.
*
SLOPE and RELEASE are similarly affected by
changes to BREAK POINT and/o: SUSTAIN levels.
The bigger the
defference
between starting 8 end-
ing levels. the longer the actual time produced by
a
particular Rate value.

BREAK P. (Break Point, Level)
‘Q
,
Determines the envelope level at which the Decay rate
changes to the Slope rate. This allows complex two-
part decay or decay/attack transients
lo
be created
(see Slope description below for examples).
l If the Break Point level is set to maximum
(
3
:
).
the
extra envelope stage is effectively disabled, and the
envelope becomes a conventional
ADSR
type. (In
this case, SLOPE is used instead of DECAY to set
the actual decay rate from the ATTACK peak to the
SUSTAIN level.)
*You can also produce a regular
ADSR
by setting
BREAK POINT lo the same value a$ SUSTAIN level.
This method allows DECAY to contr4l the decay rate.
but requires you to change BREAK TOINT whenever
you change SUSTAIN.

SLOPE (Rate)
I
Determines the rate at which the envelope contour
moves from the BREAK
POINTlevel
to Ihe SUSTAIN
level.
*If
the Break Point level is LOWER than the Sustain
level, then SLOPE functions as a second
ATrACK
(the envelope moves UP lowards the Sustain level).
-If
the Break Point level is HIGHER than the Sustain
level, then SLOPE functions as a second DECAY (the
envelope moves DOWN towards the Sustain level).
*Slope has no effect when Break Point and Sustain
are set to the same value.

SUSTAIN (Level)
Determines the constant envelope level at which the
sound is sustained after the Attack, Decay and Slope
phases are completed, for as long as the key is kept
deoressed.

RELEASE (Rate)
Determines the rate at which the envelope contour
falls from the Sustain level to zero after the key is
released.
-If
the envelope has not yet reached the Sustain level
(if still in the Attack, Decay or ‘slope phase), then
the envelope level will fall from its CURRENT value
to zero at the Sustain rate.
l
As
wilh
Decay and Slope, changing the Sustain level
automatically changes the actual Release TIME
(because Release is a rate.).
