ACCESS VIRUS OS4

LFO 1 – Panel

TRANSPOSE Transposes the entire 
SINGLE program by octaves. If your 
Virus is equipped with a built-in 
keyboard, the selected SINGLE pro-
gram is not transposed. Instead, 
the keyboard is transposed glo-
bally. 

RATE Determines the speed or rate 
of the LFO. 
In polyphonic sounds, the manu-
ally selected RATE value deviates 
slightly from voice to voice to liven 
up the sound of the LFOs, which 
also oscillate polyphonically. When 
the LFO is synced up to the master 
clock, the desired note value is 
selected via the RATE knob.

SHAPE Determines the waveshape 
of the LFO. You can select from a 
sine, triangle, sawtooth or pulse 
wave. WAVE opens a local menu. 
Here you can select 64 further LFO 
waveshapes in the display using 
the VALUE knob or the VALUE but-
tons. You can chose from a stepped 
random modulation (S&H; short 
for Sample & Hold), a smooth ran-
dom modulation (S&G; short for 
Sample & Glide) and 62 cyclic mod-
ulations that are based on the 
oscillator modes. The latter allow 
you to create interesting rhythmic 
LFO modulations.
