| Operating
system |
| In
April 2000 Yamaha released the V1.13
operating system for the RM1x, you may
already have the latest OS (see checking
your OS) if not you may want to upgrade
to the new version. As an RM1x owner you
are entitled to FREE updates of the OS,
which will be arranged by your dealer.
Comments left on the message board said
that some dealers are refusing to order
the new ROM's unless you can specifically
identify the problems in the old OS. I
decided to fit the ROM myself and ordered
the chip direct from Yamaha, all it took
was a five minute phone call and they did
not ask if I had any problems with the
old OS. To order the chip yourself see
the final page of the owner's manual for
the phone number of the Yamaha
distributor in your country (UK
01908-366700) the part number is
XV161GO1. You will however need a credit
card as you will be charged £50 which is
credited back to you when you return the
old ROM. |
| Fitting
your own ROM |
| The
only tools you will need to fit the new
ROM are an anti-static wrist band (£5)
and a chip extractor (£1), without these
you risk damaging the chips in the RM1x
with static electricity and bending the
old ROM as you lever it out with a screw
driver etc. The first thing to do is
remove your RM's knob's, which sounds
more painful than it actually is, they
just pull off. Next remove ALL the screws
at the back of the unit, not forgetting
the one which holds in the cable tie and
taking note of which of the two types go
where. Flip your RM over and place it on
a surface that won't scratch it and
remove ALL the screws on the underside,
even the one in the middle. With a bit of
manoeuvring you should now be able to
remove the under casing of the RM leaving
all its guts secured in the top shell of
the machine. Looking inside the unit you
should be able to see two chips in the
middle of the machine that look like the
new ROM. If you look very carefully at
the printed circuit board at the end of
the chips you will see these are labelled
IC2 and IC3, the one you need to remove
is IC2. Carefully but firmly pull on the
chip with your extractor tool and it
should come out relatively easily, then
without touching the pins of the new chip
sit it on top of the holder so that the
pins fit neatly into the small holes.
Care should be taken to ensure the chip
is the right way round, there is a small
indent in one end of the chip which
should be lined up with the dent in the
white line surrounding the chip holder on
the circuit board. Give the chip a firm
push exerting pressure on the whole of
the chip at the same time to ensure all
the legs click into place in one go. To
finish off fit the base panel, replace
all of the screws and stick your knob's
back on, provided nothing has gone wrong
when you power up your RM in the test
mode you should now read MAIN ROM V1.13. |

| Check
your OS |
| With
your RM1x turned off press and hold the
PATTERN, PATT CHAIN & UTILITY BUTTONS
and turn the power on.You should now be
in the RM1x test screen, next to the
heading MAIN ROM is the OS version
number.The laterst version is V1.13. |
| What's
it all about ? |
| The
only difference in the latest ROM that I
am aware of is that a reset command is
not sent from the midi out when the stop
or rewind buttons are pressed on the RM.
This is helpful if you are using external
midi gear but can also be avoided by
having the voice of the channel the
outboard gear is on set to anything
except "phrase". |
| Should I
fit my own ? |
| Fitting
the the OS ROM yourself may damage your
RM1x if not done correctly, this may not
be covered by the units warranty. Only
fit the ROM yourself if you have suitable
experience and knowledge and are prepared
to accept the consequences ! |
