The Parameters
 
TRI    Linear FM with a bipolar tri-
angle generated by Osc1.
 
WAVE    The selected Osc1 wave 
is the FM source. This lets you in 
some cases create typical DX7-FM 
sounds (here OSCILLATOR 1 SHAPE 
should be set to WAVE).
 
NOISE    The noise generator is 
the FM source (see also NOISE 
Color). Excellent for drum sounds.
 
INPUT    Here the mono or stereo 
signal from external analog inputs 
or from an internal aux bus may be 
routed to the frequency modula-
tion. The input FM is in real stereo, 
even in connection with UNISON 
mode.

FILT ENV -> PITCH This parameter 
determines the intensity at which 
the filter envelope controls the 
pitch of the second oscillator 
(PITCH OSC 2).
FILT ENV -> FM It determines the 
intensity at which the filter enve-
lope controls the frequency modu-
lation (FM AMOUNT). This as well 
as the previous parameter are ”rel-
ics” from the predecessor model of 
the Virus. Modulations such as 
these may also be implemented 
via the Modulation Matrix (see the 
section ”ASSIGN” below).
