DIGITAL
FUNCTIONS
The
microprocessor,
in
addition
to
storing
programs,
directs
and
controls
all
Level
2
functions.
Some
of
the
Level
2
functions,
such
as
Auto
Trig
and
Interface
on-off,
are
basically
"change-of-status"
functions,
and
require
little
memory
The
"recording"
functions
—
the
sequencer,
the
arpeggiator,
and
the
program
sequencer
-
require
recording,
not
only
of
status
and
voltage
amounts,
but
of
time
values.
This
requires
a
time-measuring
circuit,
so
the
low-frequency
oscillator
(LFO)
is
used
as
a
clocking
circuit.
The
resulting
pitch
and
timing
information
is
stored
in
memory,
and
recalled
when
the
appropriate
"real-time"
function
is
selected.
THE
SEQUENCER
In
the
sequencer
record
mode,
the
microprocessor
determines
and
stores
trigger
status
and
keyboard
control
voltage.
When
the
sequencer
mode
is
activated,
the
LFO
is
unconditionally
set
at
67
Hz.
This
allows
timing
discrimination
of
7.5
milliseconds
(the
duration
of
a
note
will
never
be
off
by
more
than
7.5
milliseconds).
The
sequencer
stores
every
change
in
trigger
status
and
every
change
in
keyboard
voltage,
whether
or
not
they
occur
simultaneously.
The
following
musical
example:
will
be
stored
in
this
manner.
