SHAPE
This control feature lets you determine the waveshape for the WAVE section (one of 64 variable
spectral waveshapes). The waveshape is infinitely variable from sawtooth through to pulse waves.
Wave or pulse width selection is executed via the SHAPE and WAVE SEL/PW control features (see
appropriate section): If SHAPE has a value less than the value of the center position, then WAVE
SEL/PW determines the waveshape; if the SHAPE value is higher than that of the center position,
then WAVE SEL/PW determines the pulse width.
WAVE SEL/PW
has two functions, depending on the SHAPE (see appropriate section) value:
> When SHAPE has a value lower than that of the center position, then WAVE SEL/PW lets you
select from the 64 spectral waveshapes available in the ROM of the Virus. Waveshape 1 is a sine
wave; No. 2 a triangle, the remainder of the waves feature different combinations of frequencies.
> When the SHAPE value is higher than that of the center position, then WAVE SEL/PW determines
the pulse width: At the far left position the pulse width is 50%, at the far right it is 0%, which
means the wave no longer oscillates.

Description
In polyphonic mode, each of the voices involved is assigned a dedicated
LFO.
In polyphonic mode, all voices are assigned the same LFO.
