These
parameters
determine the
time settings (Tl, T2, T3
and T4) and the
level settings (LI, L2,
L3
and L4)
of the
TVF
envelope.
The
'T"
parameters indicate
the time it takes for the
cutoff frequency to
reach the next
cutoff
frequency.
(For example,
Tl is the time it takes the
cutoff frequency to change
from Note On to
LI).
The "L"
parameters
determine the amount by which
the cutoff frequency is changed
at each point.
Range:
T
= 0—
127/L1
=0—
127
T
: The
greater the
value, the longer the time
it takes to reach the next level.
L
: The
greater the
value, the higher the cutoff
frequency.
The
value set
here
follows adjustment by
the TVF envelope depth before
changing the
cutoff
frequency.
