ABOUT LAST
STEP AND
SCALE
The default setting
is
4/4 time, shown
by
the
red
light
at
the left
side
of the chart. In this,
the lowest
of the four
chart lines,
the 16
Main
Keys
are shown
divided into 1 bar of 4 crotchets, therefore
the
value
represented
by
each Main
Key is a
semi-quaver,
or
1/16 note.

A bar of 4/4 time
To enter the Pattern other
than
above, such
as 3/4,
a
bar consists
of
12. steps,
so it
is
necessary
to
change the
total
step
number from 16
to 12. (See
a. Setting Last
Step on page

A
bar of
3/4
time
The chart line second from the
bottom
is
divided
into half
a
bar of two
crotchets, in
which the 16
Main
Keys
represent
a
dem (semiquaver, or
1/32
note. Although patterns may be only half-a-bar
long,
two patterns may
be chained
to play consecu-
tively.
(See c. Chaining patterns
together
on
page
29.)
The third line
up
on the
chart
is similar
to
the
first,
except for
three
beats
(or
6)
in the bar
instead of
common time. The
fourth
line is similar to the
second line, but again caters for
3
or
6 beats
in
the
bar. The Scale may be
set to
any of the
lines. (See
b.
Setting
Scale.)
The Pattern of
4/4
with
triplets also
consists of 1
2
steps. If, however,
entering the
Pattern
with the
Scale set
to 4/4,
the
total piaying
time will
be
three
quarter of
the common
time.
So,
it
is necessary
to
change the time of
each
step. (See
b.
Setting
Scale.)
The
Last Step is set
so that
