KEY TRIGGER
Activates the synchronization of the LFOs at the start of a note: The LFO no longer oscillates freely, it
restarts its wave cycle at the beginning of each note.
With the function KEY TRIG PHASE in the EDIT menu, you can select the position within the wave cycle
at which you want the LFO to start oscillating at the start of a note.

AMOUNT
This button does not actually control a parameter, it opens a local menu. This menu contains
independent modulation intensities for controlling the following parameters via LFO 2:
independent modulation intensities for controlling the following parameters via LFO 2:
SHAPE 1+2
The SHAPE parameters of both oscillators jointly
FM AMOUNT
The Frequency Modulation Intensity
FILTER 1
The frequency of the first filter
FILTER 2
The frequency of the second filter

While you are dealing with one of the parameters discussed here, the corresponding LED will
flash. If this parameter is assigned a value other than 0, the LED will illuminate continuously
when you exit the menu.
Between the two positions FILTER 1 and FILTER 2 you will find the position FILTER 1+2, which
flash. If this parameter is assigned a value other than 0, the LED will illuminate continuously
when you exit the menu.
Between the two positions FILTER 1 and FILTER 2 you will find the position FILTER 1+2, which
lets you jointly control the modulation intensities of both oscillators. In this position, the
FILTER 1 and FILTER 2 LEDs flash.
FILTER 1 and FILTER 2 LEDs flash.

SHAPE
This control feature lets you determine the waveshape for the WAVE section (one of 64 variable
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
WAVE SEL/PW has two functions, depending on the SHAPE (see appropriate section) value:
WAVE SEL/PW has two functions, depending on the SHAPE (see appropriate section) value:
1. When SHAPE has a value lower than that of the center position, then WAVE SEL/PW lets you select
from the 64 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.
