ACCESS VIRUS OS4

Menu parameters for Oscillator-2

KEY FOLLOW Determines the 
intensity of the pitch control via 
the keyboard: At the value +32 
(standard setting) the oscillator is 
controlled normally, i.e. the octave 
you are playing is identical to the 
oscillator octave; at +63 every 
ascending octave you play trans-
poses the oscillator upwards by 
two octaves (whole note scale); +15 
transposes the oscillator upwards 
by one octave for every two 
ascending octaves you play (quar-
ter note scale); at 0 the keyboard 
control option is off.  Negative val-
ues generate opposite control 
intensities.

FM MODE Oscillator 2’s frequency 
modulation can be executed in a 
variety of ways using a different 
signal or modulation sources. You 
can also select an external audio 
signal for frequency modulation. 
Set the intensity of the modulation 
via the FM AMOUNT knob. Choose 
the sine wave for Oscillator 2 in 
order to achieve the most trans-
parent form of frequency modula-
tion. Here’s a look at the FM 
sources that you have at your dis-
posal:
