Oscillators
The Virus TI has a total of ve internal sound-generation sources: Three main oscillators, a sub-oscillator and
a noise generator.
Several different oscillator modes are available, each with its own distinct characteristics, including: Classic
(as in previous Virus models), HyperSaw (up to 9 layered, detunable Saw waves), WaveTable (smoothly in-
terpolated, additive waves with optional PWM), Grain Table and Formant Table (which both work by applying
granular audio techniques to the wavetables).
Oscillator 1 (Classic)
Mode •
Classic, HyperSaw, WaveTable etc.: Selects the basic type of oscillator.
Shape •
Spectral Wave ... Sawtooth ... Pulse: Waveform mix. At minimum, you will only hear one of the 64 spectral
waves, at dead centre you will hear a pure Sawtooth, at maximum a pure Pulse wave. Set intermediate val-
ues for different mixtures (these are displayed as percentages).
Modulation destination “Osc1 Shape”.
Wave Select / Pulse Width •
Two distinct functions, depending on the value of the Shape parameter (see below): If Shape is anywhere
below centre, Waveselect/PW will select a spectral wave. If Shape is set to “Sawtooth” or above, the Waves-
elect/PW knob will control pulse width instead...
Sine, Triangle, Waves 3 to 64: Spectral Wave function. Modulation destination “Osc1WaveSelect“. or 50.0%
to 100%: Pulse width function. Modulation destination “Osc1PulseWidth“.
Semitone •
-48 to +48 semitones: Adjust the pitch of oscillator 1 in semitones. Modulation destination “Osc1Pitch“.
Key Follow •
-64 to +31, Norm, +33 to +63: How much the pitch of oscillator 1 follows the keyboard (i.e. MIDI note
number). Press both Value buttons at the same time for normal tuning (Norm).
