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 
position, the sequencer you use is 
not able to playback the file cor-
rectly. 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 pro-
cedure which should take approxi-
mately 30 seconds. Now, when the 
Virus has reseted itself, you can use 
the new operating system!

There’s no danger of a flawed MIDI 
transmission burning faulty soft-
ware into the Virus’ memory. 
When the device receives MIDI 
data, this information is first buff-
ered 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 
process. The old operating system 
will remain unharmed. Only when 
you actually initiate a burn opera-

tion will the old operating system 
be deleted and overwritten with 
new data.
