These parameters determine the time settings
(Tl,
T2,
T3 and T4)
and the
level settings
(LI, L2 and
L3) of the
TVA
envelope.
The
"T" parameters
indicate the time it takes for the level
of the sound to reach from one point to
the
next; for example, Tl is the time between Note On and LI.
The
"L"
parameters determine the level
at
each point.
Range:
T
=
0—
127/L
= —
127
T : The greater the value, the longer it takes to
reach the next level.
L
: The greater
the
value, the
greater the
level.
In
the case of the
TVA, the envelope level
becomes after Note
Off.
