INSTALLING A NEW OPERATING SYS-
TEM
The Virus C, kc and indigo use an identical op-
erating system. The differences in hardware is
detected automatically.
Load the MIDI file into your sequencer and
make sure you have chosen the right MIDI
channel and port settings. The MIDI file con-
tains the new software for the VIRUS, packed
in MIDI Sysex data.
Ensure that the MIDI clock option is disa-
bled (mixing SysEx data and the MIDI clock
can lead to malfunctions of your MIDI inter-
face).
Start your sequencer to playback the MIDI-
file.
At this stage, you should be able to watch the
VIRUS counting up the received blocks. If the
display shows ”RECEPTION FAILED,” then a
transmission error has occurred. This can be
caused by a buffer overrun of the MIDI inter-
face. In this case, you will need to upload the
entire file again. Lower the tempo of your se-
quencer before uploading (e.g. 60 bpm). To pro-
ceed, press any key followed by STORE which
will again enable the receive mode. In case that
the load procedure simply stops at a certain po-
sition, the sequencer you use is not able to
playback the file correctly. In this case, you
need to use another sequencer.
After a successful upload, press STORE to burn
the new operating system into the flash-ROM.
Never switch off the VIRUS while burning the
data! Please ensure stable power conditions
during this procedure which should take ap-
proximately 30 seconds. Now, when the VIRUS
has reseted itself, you can use the new operat-
ing system!
There’s no danger of a flawed MIDI transmis-
sion burning faulty software into the VIRUS’
memory. When the device receives MIDI data,
this information is first buffered in the delay
memory of the VIRUS, where it is checked for
errors. If the device finds an error, the loading
routine is aborted and it will generate an error
message. Then you can try repeating the proc-
ess. The old operating system will remain un-
harmed. Only when you actually initiate a burn
operation will the old operating system be de-
leted and overwritten with new data.
LOADING THE OS FROM ONE VIRUS 
TO ANOTHER
Connect the sending VIRUS’ (VIRUS 1) MIDI
Out port to the receiving VIRUS’ (VIRUS 2)
MIDI In port.
Switch on VIRUS 1 while you’re holding the
[Store] button pressed. The display will read
SYSTEM UPDATE.

Then press the [Value +], [Store], [Store] but-
tons in this sequence.
Ensure that VIRUS 2 is connected and then
press VIRUS 1’s [Value +] button to launch the
operation. 
The operating system will be loaded to VI-
RUS 2. You’ll see that this is the case by the
fact the both devices will indicate high num-
bers in their displays.
