Issues

What
MIOI
channels
does
the FR-3x u
se
by
default?
See
the
table
on
page

•
The
FR-3x
does
not change sounds when my
sequencer
tr
ans
mits program change
nUl11bers
.
The
program
change
number probably outside
the
range
of
the
FR-3x's
registers
(see
"Program
change
messages"
on
p.
71
).
Such
"e
x
cess"
programnumbers
are
ignored
by
the
FR-3
x.
•
The
FR-3x
does
not receive the MIOI
messages
I
recorded
for
it.
That's
beca
u
se
the
"Mld" parameter
is
cu

Set
it
to
"I

(page

•
The
external sequencer
keeps
displaying a "MIOI

message
T

This
leads
to
a
coarser
resolution, andmaybe
to
audible
steps,
but
at
least,
your

w
ill
be
able
to
record
