FILT 1 SELECT
FILT 2 SELECT
This control feature is used to allocate the three knobs RESONANCE, ENV AMOUNT and KEY FOLLOW
to the first filter, second filter or both filters. The currently active assignments are indicated by the
integrated LEDs. To control both filters simultaneously via the knobs, you must first press both buttons
simultaneously. SELECT pertains to the corresponding knob located on the Virus only, but not to the
sound parameters it controls. These parameters exist  separately in both filters regardless of the SELECT
setting. This is why for instance you should control the resonances of the respective filters via different
MIDI Controllers. In actuality SELECT only determines if the knob in question sends its value to the first
filter, second filter or both filters.
ATTACK
Determines the amount of time it takes for the filter envelope to rise to its maximum level. The higher
the ATTACK value, the longer it takes for the envelope to rise to maximum volume after the start of a
note.
