TYPE2
In this screen,
you
can
make
a
loop.
You
can
make
a stable sustain
sound more
successfully
if
using
the continuation
of similar
waves.
When
the
Loop Mode
FWD
(Forward)
is
selected, the
left
side of
the
center
line
shows
the
waveform up
to
the
End
point,
and
the right side
shows
the
waveform
from
the
Loop
point.
By
connecting
waves
deftly
on
this
line, a
natural sustain
sound
can be obtained.

POINT-
LOOP POINT
In
the
Loop
Mode
ALT
(Alternate), the center
line
becomes
the
Loop
point
when
the cursor
is
put on
the
Loop
position.
Therefore,
you
can
see the
waveform
turned back
at
the
Loop
point.
When
the cursor
is
on
the
End
position,
the
waveform
is
turned back
at
the
End
point.
In this
mode, though,
looping
is
normally
quite
difficult.
