We use lters in synthesizers for changing and shaping the timbre of a sound. The Virus TI Snow has two
lters, which can be run in series or parallel. ‘Series’ means that the output of Filter 1 goes straight into Filter
2, and it is the output of Filter 2 that you hear.

‘Parallel’ means the oscillator signal is divided into two channels, one of which goes into Filter 1, the other
into Filter 2. In this case, you hear a mixture of the outputs of both lters. The following parameters are avail-
able to edit via the 3 Value knobs.
Mod Menu
Please select patch “Tutorial 5” RAM8 8-5). Press EDIT/SHIFT + MOD to enter the Modulation menu.
‘Modulation’ is the term used to describe a function which changes the value of another parameter over
time. Specically for this purpose, the Virus has 3 LFOs or ‘Low Frequency Oscillators’. These are different
from the oscillators used to generate the sound, as they operate at much lower speeds.
The LFOs have been designed to run at an independent rate, or to slave to the overall tempo of the current
patch or Multi. If they are set to Rate, then you can choose a value between 0 - 127, and if they are set to
Clock, you can choose a divider setting, based on a whole bar of 4/4, whereby 1/4 represents a rate equiva-
lent to quarter notes or crotchets.
