OCILLATOR
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 interpolated, 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 values 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 Waveselect/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).
PARAMETER REFERENCE MANUAL12
Balance •
-64 to +63: Adjusts the relative levels of oscillator 1 and oscillator 2 (including FM), whereby -64 is oscillator 1 only and +63 is oscillator 2 only. Note that this parameter is mirrored in the oscillator 2 menu. Modulation destination “Osc Balance”.
Oscillator 1 (HyperSaw)
This information only applies to oscillator 1 in HyperSaw mode
Mode •
Classic, HyperSaw, WaveTable etc.: Selects the basic type of oscillator.
Density •
1.0 to 9.0: The number of sawtooth waves used. The volumes are cross-faded for completely smooth transitions. Modulation destination “Osc1 Shape“.
Spread •
0 to 127: Detuning of individual sawtooth waves within the HyperSaw. Modulation destination “Osc1
PulseWidth”.
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).
Balance •
-64 to +63: Adjusts the relative levels of oscillator 1 and oscillator 2 (including FM), whereby -64 is oscillator 1 only and +63 is oscillator 2 only. Note that this parameter is mirrored in the oscillator 2 menu. Modulation destination “Osc Balance”.
Sync •
Off, On: Switches oscillator 1 Sync off/on.
Unlike Classic oscillators where oscillator 2 can be synchronized to oscillator 1, HyperSaws are always synchronized to their own internal sync oscillator. In HyperSaw mode, FM Amount controls a frequency offset
OCILLATOR
parameter instead, controlling how much higher the pitch of the oscillator is than its master. To differentiate
this function from standard oscillator synchronization, it is called Sync.
Modulation destination “Osc2 FM Amount”.
About HyperSaw and SubOscillators : Similarly, HyperSaw oscillators also have their own integrated sub
oscillators - up to 9 square waves tuned an octave below the main oscillator, one for each saw wave.. To differentiate these from the Classic sub oscillator, they are called HyperSub. The sub oscillator volume control
cross-fades between the main HyperSaw oscillator and its HyperSub.About HyperSaw and SubOscillators.
Similarly, HyperSaw oscillators also have their own integrated sub oscillators - multiple square waves tuned
an octave below the main oscillator. To differentiate these from the Classic sub oscillator, they are called HyperSub.
Sync Frequency •
0 to 127: Adjust the frequency of the internal sync oscillator. If sync is set to off, this parameter will be not
available.
Oscillator 1 (WaveTable)
Mode •
Classic, HyperSaw, WaveTable etc.: Selects the basic type of oscillator.
Index •
0 to 127: This determines the playback position within the currently selected Wavetable. Each of the 128
available values represents either a particular wave or the interpolation of the two nearest waves. Modulating
the Index of a wavetable with an LFO or Envelope will often result in a highly-dynamic variation in the timbre
of a sound, impossible via any other means.
Table •
Sine ... Domina7rix: Selects one of many wavetables.
Interpolation •
Use this parameter to determine how smoothly the different waves in the current Wavetable are blended into
each other as the Wavetable Index of the respective oscillator is swept.
Since the number of waves differs with each Wavetable, the result of this will depend on which table you
have selected.
Each Wavetable refers to a selection of different original waves, through which the oscillator can sweep in realtime. At the default (0) setting of Interpolation, each of the 128 positions of the Wavetable Index represent
PARAMETER REFERENCE MANUAL14
a unique mix of the two nearest waves, resulting in a smooth morphing of the timbre as you sweep the Index
position.
With Interpolation at zero position, the waves are blended as smoothly as possible, with the mid-point
between each wave representing a 50/50 mix of the two nearest waves. As you increase the value, an increasingly large “dead-zone” is created between each of the original waves, and the blend rate is increased
accordingly until, at the maximum value (127), a stepping effect is achieved.
The net result is a very different characteristic from when the waves are blended smoothly, in two very important ways: rstly, that slow LFO modulations of Wavetable Index will generally result in a somewhat rhythmic
effect that is difcult to achieve by other means, and secondly, the original waves will be presented much
more distinctly, and may often appear much brighter as a result (not that they are, mind - it’s just that pinpointing the exact value out of 128 possibilities at which a wave is not blended with any other, can be rather
tricky!)
Interpolation is also available as a destination in the Mod Matrix (Osc1/2 Interpolation).
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).
Balance •
-64 to +63: Adjusts the relative levels of oscillator 1 and oscillator 2 (including FM), whereby -64 is oscillator 1 only and +63 is oscillator 2 only. Note that this parameter is mirrored in the oscillator 2 menu.
Modulation destination “Osc Balance”.
Oscillator 1 (Wavetable PWM Oscillator)
The WavePWM oscillator takes two instances of the same wavetable, and phase-shifts them against each
other to achieve an effect reminiscent of the traditional pulsewidth modulation of a pulse wave oscillator.
Mode •
Classic, HyperSaw, WaveTable etc.: Selects the basic type of oscillator.
Index •
This determines the playback position within the currently selected Wavetable. Each of the 128 available values represents either a particular wave or the interpolation of the two nearest waves. Modulating the Index of
OCILLATOR
a wavetable with an LFO or Envelope will often result in a highly-dynamic variation in the timbre of a sound,
impossible via any other means.
This parameter can be modulated via the Mod Matrix and the LFO’s - please select Wavetable 1/2 Index
from the list of available destinations
Please note that Table 0 (Sine) contains only a sine wave, and as such, the Index parameter will have no effect on it.
Wavetable •
Selects the current Wavetable - each being a unique collection of different waves from which all manner of
different timbres may be achieved.
PulseWidth •
At zero position, all the even-numbered harmonics are cancelled out, creating a hollow sound similar to a
50% pulse wave - when the value reaches 127, the whole wave is almost entirely cancelled out, resulting in
a much thinner sound.
This parameter can be modulated via the Mod Matrix and the LFO’s - please select Osc1/2 Pulse Width
from the list of available destinations
Detune •
As with traditional PWM, much of the fun comes from modulating the pulsewidth by an LFO, which creates
the characteristic warmth of detuned oscillators - the Detune parameter creates this effect automatically,
with no further modulation assignments.
Interpolation •
Use this parameter to determine how smoothly the different waves in the current Wavetable are blended into
each other as the Wavetable Index of the respective oscillator is swept.
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).
Balance •
-64 to +63: Adjusts the relative levels of oscillator 1 and oscillator 2 (including FM), whereby -64 is oscillator 1 only and +63 is oscillator 2 only. Note that this parameter is mirrored in the oscillator 2 menu.
PARAMETER REFERENCE MANUAL16
Hint: If you do not make use of either the PulseWidth or Detune parameters, switch back to Wavetable mode
to save on DSP and increase polyphony!
Tips for auditioning the Wavetables
As with the majority of the Wavetable content, it is advisable to audition them at relatively low pitch (we suggest setting Oscillator Semitone to -24). This is because the lowest audible frequency (the fundamental) in
any table is always pitched to middle C3, but in many of the brighter-sounding tables, the fundamental plays
little part in the overall timbre, and the upper harmonics (often where all the action is) can be very difcult to
perceive at high pitch, or are simply ltered out altogether.
Since there are many differences between the tables in terms of their spectral dynamics, it is a good idea
to audition them all in a variety of different ways. Simply sweeping through the Index by hand is one way,
but can give very misleading impressions as to the usefulness of the table. Try rst with a slow LFO (triangle
wave) and then a fast envelope sweep in both directions to get a better idea of what the table may or may
not be good for.
Remember, for those tables with several contrasting waves, subtle modulation is often the key.
Don’t forget to try them all with different settings of the new Interpolation parameter.
Oscillator 1 (Simple Grain Table)
The remaining oscillator modes all make use of a new technology for the Virus TI, called Grain Table. The
basic idea behind this technology, is to take the existing wavetables, and apply similar techniques as
those used in some granular sampling and pitch-shifting algorithms to open up a whole new world of
possibilities. Each of the two main types: Grain Table and Formant Table are presented in both Simple
and Complex formats. In each case, the Simple mode offers fewer parameters, and a higher polyphony
than Complex, with the values of parameters common to each mode remaining constant.
It’s important to note that the characteristics of the Grain Table and Formant Table oscillators are quite
different to those of traditional “granular” sampling/synthesis techniques, which tend to be associated with other-worldly “clouds” of sound. In the Virus TI, we have instead employed the technology to
achieve a very musical result which should prove every bit as useful as the other oscillator types in all
manner of musical projects.
Mode •
Classic, HyperSaw, WaveTable etc.: Selects the basic type of oscillator.
OCILLATOR
Index •
Determines the playback position within the currently selected Wavetable. Each of the 128 available values
represents either a particular wave or the interpolation of the two nearest waves. Modulating the Index of a
wavetable with an LFO or Envelope will often result in a highly-dynamic variation in the timbre of a sound,
impossible via any other means.
This parameter can be modulated via the Mod Matrix and the LFO’s - please select ‘Wavetable 1/2 Index’
from the list of available destinations
Please note that Table 0 (Sine) contains only a sine wave, and as such, the Index parameter will have no effect on it.
Wavetable •
Selects the current Wavetable - each being a unique collection of different waves from which all manner of
different timbres may be achieved.
Formant Shift •
Use this parameter to sweep the pitch of the formants in the wavetable by +/- 64 semitones. The effect is
reminiscent of oscillator sync, and can be useful for both extreme lead sounds (try broad sweeps!), as well
as subtle timbral variations.
The movement within a wavetable will still be recognisable as you sweep through the Index points, but you
will notice a very different character to the same table as played by the standard Wavetable oscillator.
A useful property of the Simple version is that the fundamental frequency can always be heard, no matter
where you set Formant Shift.
This parameter can be modulated via the Mod Matrix and the LFO’s - please select Osc1/2 Formant from
the list of available destinations.
Hint: Use the Simple modes where possible if polyphony is a concern - they eat a lot less DSP power than
the ‘Complex’ modes.
Interpolation •
Use this parameter to determine how smoothly the different waves are blended you sweep the index parameter.
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).
PARAMETER REFERENCE MANUAL18
Balance •
-64 to +63: Adjusts the relative levels of oscillator 1 and oscillator 2 (including FM), whereby -64 is oscillator 1 only and +63 is oscillator 2 only. Note that this parameter is mirrored in the oscillator 2 menu.
Oscillator 1 (Complex Grain Table Oscillator)
Here we have the purest application of the Grain Table technology - and a very powerful oscillator indeed.
Mode •
Classic, HyperSaw, WaveTable etc.: Selects the basic type of oscillator.
Index •
Determines the playback position within the currently selected Wavetable. Each of the 128 available values
represents either a particular wave or the interpolation of the two nearest waves. Modulating the Index of a
wavetable with an LFO or Envelope will often result in a highly-dynamic variation in the timbre of a sound,
impossible via any other means.
This parameter can be modulated via the Mod Matrix and the LFO’s - please select Wavetable 1/2 Index
from the list of available destinations.
Please note that Table 0 (Sine) contains only a sine wave, and as such, the Index parameter will have no effect on it.
Wavetable •
Selects the current wavetable - each being a unique collection of different waves from which all manner of
different timbres may be achieved.
Formant Shift •
Use this parameter to sweep the pitch of the formants in the wavetable by +/- 64 semitones. The effect is
reminiscent of oscillator ‘sync’, and can be useful for both extreme lead sounds, as well as subtle timbral
variations.
At 12 o’clock position, the sound will be identical to that of the standard Wavetable oscillator. As you sweep
through the other values you will hear a fascinating shift in the spectra of harmonics, and a very different
character to the same wavetable played by the standard Wavetable oscillator.
In contrast to the Simple version, the fundamental frequency is shifted along with the rest of the wave, resulting in a more dramatic effect.
This parameter can be modulated via the Mod Matrix and the LFO’s - please select Osc1/2 Formant from
the list of available destinations.
OCILLATOR
Formant Spread •
By adjusting the spread of the formants, a very complex effect is achieved - something like an unholy alliance between a sub-oscillator and a sync-sweep could be one way of describing it, although the depth of
the effect is highly-dependent on the current value of Formant Shift.
For an effective demonstration, try sweeping from 0 (default) through to 127, with Formant Shift set at 12
o’clock position.
This parameter can be modulated via the Mod Matrix and the LFO’s - please select Osc1/2 Spread from the
list of available destinations.
Local Detune •
Use this parameter to achieve the effect of two detuned oscillators an octave apart. Note that this parameter
is most effective when Formant Spread is set to a relatively low value.
Interpolation •
Use this parameter to determine how smoothly the different waves are blended you sweep the index parameter.
Semitone •

Hint: Use the ‘Simple’ modes where possible if polyphony is a concern - they eat a lot less DSP power than
the ‘Complex’ modes
Oscillator 1 (Simple Formant Table Oscillator)
The Simple Formant Table oscillator is similar in concept to the Simple Grain Table oscillator, only with one
crucial difference: the formants remain xed as you play up and down the keys. This effectively turns the
oscillator into a kind of lterbank, comprising up to 256 resonant bandpass lter poles, whereby the cutoff of
each pole is determined by the harmonics in the current wavetable index.

oscillator.

Oscillator3 waveform. Note that if “Pulse” is selected here, its pulse width will follow that of
oscillator 2.
Semitone •
-48 to +48: The pitch of oscillator 3. If Slave mode is selected, this value will be ignored and oscillator 3 pitch
will track oscillator 2 pitch.
Modulation destination “Osc3 Pitch“.
Volume •
0 to 127: The level of oscillator 3 when switched on. See “Mode/Wave” above.
Modulation destination “Osc3 Volume”.
Detune •
0 to -127: Fine-tunes oscillator 3 downwards. Ignored if Slave mode (see “Mode/ Wave” above) is selected.
Modulation destination “Osc3 Detune“.
Oscillator 2 (Simple Grain Table)
Mode •
Classic, HyperSaw, WaveTable etc.: Selects the basic type of oscillator.
Index •
Determines the playback position within the currently selected Wavetable. Each of the 128 available values
represents either a particular wave or the interpolation of the two nearest waves. Modulating the Index of a
wavetable with an LFO or Envelope will often result in a highly-dynamic variation in the timbre of a sound,
impossible via any other means.
PARAMETER REFERENCE MANUAL28
Wavetable •
Selects the current Wavetable - each being a unique collection of different waves from which all manner of
different timbres may be achieved.
Formant Shift •
Use this parameter to sweep the pitch of the formants in the wavetable by +/- 64 semitones. The effect is
reminiscent of oscillator sync, and can be useful for both extreme lead sounds (try broad sweeps!), as well
as subtle timbral variations.
Interpolation •
Use this parameter to determine how smoothly the different waves are blended you sweep the index parameter.
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).
Balance •
-64 to +63: Adjusts the relative levels of oscillator 1 and oscillator 2 (including FM), whereby -64 is oscillator 1 only and +63 is oscillator 2 only. Note that this parameter is mirrored in the oscillator 2 menu.
Oscillator 2 (Complex Grain Table Oscillator)
Mode •
Classic, HyperSaw, WaveTable etc.: Selects the basic type of oscillator.
Index •
Determines the playback position within the currently selected Wavetable. Each of the 128 available values
represents either a particular wave or the interpolation of the two nearest waves. Modulating the Index of a
wavetable with an LFO or Envelope will often result in a highly-dynamic variation in the timbre of a sound,
impossible via any other means.

Wavetable •
Selects the current wavetable - each being a unique collection of different waves from which all manner of
different timbres may be achieved.
Formant Shift •
Use this parameter to sweep the pitch of the formants in the wavetable by +/- 64 semitones. The effect is
reminiscent of oscillator ‘sync’, and can be useful for both extreme lead sounds, as well as subtle timbral
variations.
Formant Spread •
By adjusting the spread of the formants, a very complex effect is achieved - something like an unholy alliance between a sub-oscillator and a sync-sweep could be one way of describing it, although the depth of
the effect is highly-dependent on the current value of Formant Shift.
Local Detune •
Use this parameter to achieve the effect of two detuned oscillators an octave apart. Note that this parameter
is most effective when Formant Spread is set to a relatively low value.
Interpolation •
Use this parameter to determine how smoothly the different waves are blended you sweep the index parameter.
Semitone •
-48 to +48 semitones: Adjust the pitch of oscillator 1 in semitones. Modulation destination “Osc1 Pitch“.
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).
Balance •
-64 to +63: Adjusts the relative levels of oscillator 1 and oscillator 2 (including FM), whereby -64 is oscillator 1 only and +63 is oscillator 2 only. Note that this parameter is mirrored in the oscillator 2 menu.
