ACCESS VIRUS OS4

Input

the Virus, so the noise level of the 
analog-digital converter increases 
automatically. Consequently you 
should dial in the cleanest, loudest 
possible signal at the external 
sound generator. The Virus fea-
tures a signal level indicator that 
allows you to monitor the signal 
level visually: see LED MODE in the 
CTRL menu. (see “LED MODE” on 
page 181).) You should only turn up 
the INPUT BOOST when you are 
unable to dial in a sufficient signal 
level prior to the external inputs. 
At a value of 0, the signal level is 
not boosted at all.

This is a global parameter, i.e. it 
affects all involved PARTs and 
INPUT DIRECT THRU (see para-
graph below). It is not stored along 
with the SINGLE PROGRAM.

In the Virus you have the option of 
using the external analog inputs 
instead of the internal oscillators 

as signal sources that can be pro-
cessed by the filters, envelopes and 
the internal effects. In addition to 
the external analog inputs, you 
also have two internal stereo aux 
paths or subgroups available as 
signal sources in MULTI MODE. The 
output signals of other PARTs can 
be routed via their respective OUT-
PUT SELECTs (see appropriate sec-
tion) to these aux paths.

You can chose from:

 

OFF    The PART is not assigned 

an external input but works with 
its own sound sources (the oscilla-
tors and the Noise Generator) in 
the manner of a conventional ana-
log synthesizer.

 

DYNAMIC    Instead of the inter-

nal sound sources, an external sig-
nal source is routed to the filter 
section. The envelopes remain 
functional so you have to play 
notes in order to hear the external 
signal source. For instance in this 
mode you can manipulate the vol-
ume to “chop up” the input signal 
much the way a gate does. If you 
turn FILTER KEY FOLLOW up, the 
input signal is filtered by a differ-
ent filter frequency depending on
