MIDI Monitor'
The MIDI
Monitor function
allows
you
to
view
data transmission/reception
between
the
U-20 and
external
MIDI
devices.
The MIDI
Monitor puts
the data received
from MIDI IN
or the data transmitted
from MIDI
OUT
into
a monitoring
buffer,
and
displays
it
in
hexadecimal
form.
The
buffer can hold 256
bytes,
and new
data
will
overwrite
the old
data.
