Appendix
 On non-part-sensitive parame-
ters the part number is ignored, but 
must still be sent as any value.
 The Virus can be switched 
between Multi Mode and Single 
Mode by parameter C123 Part Num-
ber.
 Remarks for editor/librarian pro-
grams Not all 256 bytes of a Single 
or Multi Dump are defined as a 
parameter. Some of them are 
defined for internal use or reserved 
for future applications. In a bulk 
dump these byte should not be 
changed, they should be sent to the 
Virus on the same value as they 
were received in the dump.
 One of the internal parameter 
(Page A #0) is the Sound Version 
Number. On future Virus system 
updates new parameters will be 
defined. When the Virus receives an 
older sound, the new parameters 
will be set to default values in the 
edit buffer and the version number 
will be updated automatically. The 
Virus update algorithm can be used 
from outside just by sending a 
dump and requesting it back. To 
prevent incompatibilites and confu-
sion, the Sound Version Number 
should not be changed by any other 
device that the Virus itself. When 
sounds are imported into a soft-
ware library, they should be auto-
matically pathed through the Virus 
first, before allowing a change of 
parameters. Otherwise the Virus 
might reset new parameters, when 
the sound is loaded into the Virus, 
after editing parameters.
