The Virus and Sequencers

Virtually all parameters of the 
Virus are accessible via MIDI so 
that, for example, you can manipu-
late knobs and buttons and record 
these movements to a sequencer. 
You may then route these com-
mands back to the Virus, which 
will respond to these automated 
instructions automatically. MIDI 
controllers have proven effective 
for this external control option 
since these commands – in con-
trast to system exclusive data – are 
transported very swiftly. Beyond 
that, they’re easy to edit graphi-
cally in all standard sequencer pro-
grams.

In order to be able to record the 
movements of knobs and status 
changes of buttons on the Virus to 
a sequencer, you must connect the 
MIDI Out of the Virus to the MIDI 
In of the computer or sequencer. 
You also have to enable reception 
of MIDI controllers and MIDI poly-
pressure commands in the 
sequencer so that this data is not 
subject to one-sided filtering. 
Whenever appropriate, you also 
have to enable reception of this 
automation data on the Virus. To 
this end, go to the Cntrl menu and 
take a look at the MIDI parameters. 
You’ll find a parameter called Panel 
that offers the options Internal, 
Internal+Midi and MIDI. This is 
where you determine the destina-
tion to which the knobs and but-
tons send their data. Internal 
means that the knobs and buttons 
send data exclusively to the sound 
generator and not to MIDI. There-
fore, select Internal+Midi or MIDI 
so that data is sent to the 
sequencer via MIDI. Note that the 
MIDI option disconnects the knobs 
and buttons from the Virus’ inter-
