Total Integration

The concept of totally integrating a synthesizer, which essentially means streaming audio from the Virus TI into a plug-in hosted by your digital audio workstation, certainly made some waves. Features such as sampleaccurate MIDI timing and the ability to process the output of your synth directly with other effect plug-ins are unique to the Virus TI. If you want to work with a hardware synthesizer and enjoy the benefits of a software plug-in at the same time, there is no better option.


Premium quality semi-weighted keys and loads of tactile control, including a tap tempo button, turn the Virus TI keyboard into a performer’s command station. And with pro grade D/A converters and balanced outputs at studio level, you are guaranteed to deliver a ”hot” performance. Process other instruments by feeding them through the Virus’ sound engine using the analogue inputs to open up a completely new level of interaction with your band members. And by the way, it’s built like a tank.


Three main oscillators and one sub oscillator per voice. A main oscillator can comprise of various oscillator types including the classic virtual analog oscillators (saw, variable pulse, sine, triangle, 62 spectral waves with several FM modes) and hypersaw (a multi saw-tooth oscillator with up to 9 stacked oscillators, 9 sub oscillators and sync oscillator at the same time). Wavetable oscillators with 100 multi-index wavetables, feature variable resolution and optional pulse-width modulation. Graintable oscillators apply granular synthesis techniques for independent control of pitch and formants to warp a waveform beyond recognition. Formant oscillators sound like running a signal through a massive, modulatable filterbank with hundreds of resonant bands being morphed by the wavetable index.


Two fully independent filters (lowpass, highpass, bandpass, bandstop) with an optional saturation module located in between both filter blocks. The saturation module can add one of several distortions and lo-fi effects or an additional low/-high-pass filter. Optional self-resonating Moog™ cascade filter simulation with circuit overload and 1-4 poles.


Two-dimensional modulation matrix with six slots (1 source and 3 modulation targets each). Every feasible parameter can be modulated in realtime. Three LFOs with additional hardwired destinations along with one user-definable slot. Two lightning-fast, multi-stage envelopes (ADSTR) - LFOs can be used as ramp generators as well.


The FX section has independent delay and reverb per patch (even in multi mode), along with multiple distortion/lo-fi algorithms, phaser, chorus/flanger, character control, ring modulator / shifter, EQ plus a global vocoder. There is no difference between single and multi modes - patches sound exactly the same.


Each patch contains it’s own arpeggiator pattern feat. 32 programmable steps (length and velocity can be adjusted per step) along with a global control for swing/shuffle timing and one for note lengths. Pretty much every parameter including the pattern itself, the amount of octaves and many more can be controlled using the modulation matrix.


Virus TI Desktop/Keyboard/Polar: 6 balanced outputs (@ +4dB), backed by 192 Khz/24bit D/A converters, with soft-limiting. Two inputs with 24-bit A/D. Dedicated headphone out. MIDI in, out, and thru. S/PDIF digital audio (44.1/48 kHz) inputs & outputs. USB is used for MIDI and audio transmission (adding 3 additional stereo audio outputs) and works at 12Mb/s. Virus TI Snow: 2 outputs (@ +4dB) , backed by 192 Khz/24bit D/A converters, with soft-limiting. Two inputs with 24-bit A/D. MIDI in and out. USB is used for MIDI and audio transmission (adding 3 addition stereo audio outputs) and works at 12Mb/s.


Virus TI Desktop: Sleek charcoal-gray finish, Red and white LEDs, white display, wood rail on front. I/O panel can be rotated for convenient rack-mounting. Virus TI Keyboard: Premium quality semi-weighted keyboard with 61 keys, velocity response and aftertouch. Hold and control pedal inputs. Sleek charcoal-gray finish, red and white LEDs, white display. Wood side panels. Virus TI Polar: Great synth-action keyboard with 37 keys, velocity response and aftertouch. Hold and Control pedal inputs. Winter-White finish, aluminium and wooden side panels, white LEDs and display, wood rail beneath the keyboard. Virus TI Snow: Winter-White finish, white LED and display, wood rail beneath the front panel.

Surround sound output

Every part can be panned dynamically between two stereo outputs for quadraphonic effects.

Hardware controls

Virus TI Desktop/Keyboard/Polar: 32 knobs, 43 buttons, 73 LEDs and Pitch/-Modulation wheel if applicable. Virus TI Snow: 6 knobs, 21 buttons, 18 LEDs


Virus TI Desktop/Keyboard/Polar: Between 25 to 110 voices*, depending on the complexity of the patch.

Virus TI Snow: Between 25 to 110 voices*, depending on the complexity of the patch.

*Estimates are based on single mode performance results may vary in multi mode.

Multi Mode

Multi programs can have fully-independent embedded singles, without the links to single banks required by most synths. This provides freedom from breaking other programs.


Virus TI Desktop/Keyboard/Polar: 1024 RAM and 3328 ROM sounds, 16 embedded multi patches along with 112 conventional multi slots, 16 parts in multi mode. Virus TI Snow: 512 RAM and 512 ROM patches, 64 embedded multi patches, 4 part in multi mode.

Remote Templates

Turn the Virus into a MIDI remote, the sound engine will still work independently. 32 user programmable templates to reassign most panel knobs controlling control third party plug-ins and MIDI synthesizers (TI Desktop/Keyboard/Polar only).

Smooth parameter changes

Adaptive control-smoothing provides parameter changes with no zippering artifacts. With knob quantize, a clock ratio is selected and parameter changes are updated at specified intervals only. The result is sample-and-hold parameter
movements, evocative of step sequencer sounds.


The unique DJ style audio slicer turns the Virus TI into an powerful realtime FX for
DJ applications.

Total Integration

Total Integration is our proprietary technology, which seamlessly links any Virus TI model and a computer to create a unified system consisting of a powerful hardware synth and a virtual instrument plug-in, which not only controls the Virus TI but also receives audio from it, in order to allow post-processing right inside your computer. This way you get the best of both worlds: Your Virus TI will calculate all
the voices and effects and therefore makes the CPU of your computer available for other tasks. Since it is driven by the Virus Control plug-in, the timing (unlike normal MIDI and USB-MIDI timing) will be sample-accurate, and all sound data will be saved within the song or project. Virus Control also offers sophisticated editing capabilities, along with an easy-to-use librarian page to keep track of all your Virus TI patches.

The Virus TI’s analogue input and outputs can double as an audio interface, the MIDI sockets can double as a MIDI interface. Virus Control is an VST/AU/RTAS compatible plug-in. Total Integration is certified for the following hosts: Apple Logic 8, Steinberg Cubase 4, Ableton Live 7, Digidesign Pro Tools 8, Cakewalk Sonar 7, ImageLine FL Studio 8.
