Roland EM-50 User Manual

The next message is Ctr. It means that the EM-50
is checking the checksum of the SysEx data (remem-
ber those?).
The next two messages, La and F 13h, indicate
that the data are being read from disk and that the
Flash ROM (the memory where the operating system
resides) is being updated.
3. Wait until the Core lete message is displayed,
then switch off the EM-50.
4. Hold down the [WRITE] button while switching
the EM-50 back on. This will initialize it.
5. Eject the disk and store in a safe place.
Possible error messages when using SysLoad/Sys-
Save
The following messages will abort the SysLoad or Sys-
Save operation. You thus need to repeat the entire
procedure if you manage to cure the problem or
obtain another disk.
CSumErr—The checksum of the SysEx data is incor-
rect. Ask your Roland dealer for another disk.
SysErr—A system error occurred. Try again, possibly
with another disk.
WRProt—The disk is write-protected. Disable its pro-
tection.
DskErr—The disk is probably damaged and cannot
be used.
DskFull—The remaining disk capacity does not allow
to save your data to this disk. This message is only dis-
played when you are trying to use a 2DD floppy
rather than a 2HD one for saving the operating sys-
tem.
NoDisk—You forgot to insert a floppy disk.
NoFile—The disk you inserted doesn’t contain an
operating system file. Insert the correct disk.
14.3 Updating the EM-50/30's
operating system via MIDI
The other way of updating the EM-50/30's operating
system is to do so via MIDI. In the case of the EM-30,
this is your only option. If you work with an EM-50,
you may prefer to use the SysSave function (see page
60) because it’s faster.
Note: Before updating the operating system, be sure to
archive your User Programs, Custom Styles, and song to
disk (see page 57) or via MIDI (see page 55). Updating the
system version indeed erases the entire contents of the
internal memory. Also, do not forget to make a backup of
the current system version. You may need it if turns out the
new version doesn't work.
1. Connect the EM-50/30's MIDI IN port to the
seguencer's MIDI OUT port.

For best results, use a computer with Cubase of Audio
Logic.
2. Switch off the EM-50/30, wait a few seconds, then
hold down TONE/ONE TOUCH [7] +
[METRONOME] while switching the EM-50/30 back
on again.
The display now shows the UF Hate message.
3. Start the sequencer and load the file you wish to
transfer to the EM-50/30.
4. Start playback on your sequencer.
As soon as the first data blocks arrive, the display will
show allFch w message.
5. Wait until the Come 1 ete message is displayed,
then switch off the EM-50/30.
6. Hold down the [WRITE] button while switching
the EM-50/30 back on. This will initialize it.
14.4 Initializing your EM-50/30
(Factory)
After working extensively with your EM-50/30, you
may want to recall the original factory settings. This is
not indispensable because you could use the Resume
functions in Parameter and MIDI modes to restore
the original Parameter and MIDI settings. Initializing
your EM-50/30 means that all User Program, Parame-
ter, and MIDI settings will be replaced with the origi-
nal settings — except for the Recorder song that will be
empty after initializing your EM-50/30.
Here is how to initialize your EM-50/30:
1. Power off your EM-50/30.
2. Hold down the [WRITE] button while turning
your EM-50/30 back on again.
The message Factora! will inform you that the
EM-50/30 has been initialized.
