Access Virus
Encyclopedia
The Access Virus is a virtual analog synthesizer
made by the German company Access Music GmbH. It was first produced in 1997 and has since been upgraded frequently, with the company releasing new models about every two years. Early models include the Virus A, Virus B, and Virus C series, each available in various hardware configurations. In November 2005, the Virus TI series was released, including the 61-key Virus TI Keyboard and the 37-key Virus TI Polar. A small desktop model was released in February 2008 called the Virus TI Snow. A revision of the TI series called TI2 came out in March 2009, featuring faster digital signal processing (DSP)
, greater polyphony, more effects in the effect section and a slightly changed design. The Virus series also has come out with two software plugin versions: TDM for Pro Tools
and VST
for TC Electronic
Powercore series. The term Access Virus can be used to refer to any one of these synthesizers.
, phase distortion (PD) synthesis
, frequency modulation (FM) synthesis
, and starting with the TI series, wavetable synthesis
.
All of the Viruses are DSP
-powered, virtual analog synthesizers. They have classic analog-style oscillators which can be tuned continuously from a pure sine wave
to a square wave
(with variable pulse-width modulation), as well as 63 "spectral" waveforms which are entirely synthetic, non-analog style waves. Oscillator waveforms may be modulated in a number of ways: ring modulation (AM), phase distortion (PD), or Frequency Modulation (FM). The Virus has an extensive Matrix Modulation specification. With the TI series, two new oscillator models were added: hypersaw and wavetable.
The filter
section is highly programmable, with two independent resonant filters which can be combined and modulated in various ways. The extensive Matrix Modulation specification allows for the creation of complex and detailed sounds. The Virus features a filter saturation stage as well as many different types of digital and analog-style distortion.
An outstanding feature of the TI series is "Total Integration": It is currently the only synthesizer that can be fully integrated in a current computer based audio workstation as a VST or AU plug-in, including the advantages of sample accurate MIDI timing, host automation as well as total recall.
operating system
updates. The Virus engine has largely remained the same since the Virus A up until the Virus C. They all utilize a single Motorola
DSP
chip and the sound is quite distinct between models when not factoring in the additional features provided by each hardware and firmware upgrade. The biggest effect of software optimisation is seen as a third oscillator control in the B-series menus.
The latest incarnation of the Virus, The TI, utilizes 2 DSP chips and represents the most significant technical overhaul of the Virus series since its inception.
The Virus Ti series allows for a very wide emulation of past and present synthesizers. It is a digital synthesizer but can emulate the characteristic sound and behaviour of analogue synthesizers whilst also retaining some digital features in order to broaden its sonic palette: Wavetable synthesis for example can only be found on a few other synthesizers, The PPG Wave series and Waldorf machines being notable examples. What separates the Virus' VA module from other analogue modelling synths in its price range is its twin multimode filter design and extensive modulation matrix. As of the Virus B OS4 update, it has 3 oscillators per voice (+1 sub oscillator per voice) with 2 filters per voice.
The basic Virus analogue modeled oscillators between the Virus A and TI are identical with the only difference being the number of voices available as well as the additional Hypersaw oscillator and digital wavetable oscillators of the Virus TI. Additionally, the raw Virus oscillators have much less high frequency content than the oscillators found on other subtractive virtual analogues such as the Clavia Nord Lead
and Roland JP-8000
. This partially explains the Virus's characteristically dark and bass heavy sound.
The twin multimode, highly resonant filter is also an important aspect of the Virus sound, the features of which have been extended in the Ti range to include grain table
, comb
and formant
filter settings.
Both Virus filters can be connected in series, parallel or set to process 2 oscillators independently. The routable nature of the filter allows the Virus to emulate an 18 dB/octave 3 pole filter for instance, by routing a 24dB/octave 4 pole filter in series with a 12dB/octave 2 pole filter, then turning the filter balance to 3 or 9 o'clock. Connecting a 4 pole filter in series with a 2 pole filter also allows for a 36dB/octave 6 pole filter configuration, which is unique amongst similarly priced virtual analogues. The interchangeable filters allow for such things as simultaneous high pass and low pass sweeps and filter modulation effects such as automated filter sweeps whilst still leaving a filter free for manual use.
Perhaps the most integral part of the Virus specification yet to be mentioned is its modulation matrix. Every parameter on the control surface of the synth and every parameter in every sub menu can be set as a modulation destination. The Virus also has a long list of modulation sources, including a random trigger. There are 3 modulation sources on the Virus A and B, which can be set to control 6 destinations. The Virus C and TI both allow for 6 modulation sources controlling a possible 18 modulation destinations. This does not include the 3 LFOs which can be set to modulate oscillators 1 and 2, pulse width, resonance and cutoff of both filters, stereo pan and any parameter you set as a source in the modulation matrix. Simultaneously if desired.
It is possible to emulate the unstable tuning of analogue synthesizers by setting a random source to modulate the pitch and detune of 1 or more oscillators such that every time you strike a note, its tuning will be very subtly different. The modulation matrix also allows for recursive modulation - setting a variable to modulate itself. This plays an important role in altering the behaviour of many of the control variables on the synth. For example, the Virus amplifier attack envelope is linear by default but can be changed via setting the amplifier envelope as a modulation source that modulates itself as its destination.
The Virus also has a complement of DSP effects, including a versatile distortion
unit that allows for rectification, analogue modelled and digital distortion as well as bit reducing and samplerate reducing effects. Owing to the 'blank slate' nature of many variables on the Virus (until you configure their action in the modulation matrix of course), the effects section is largely presented as yet another set of sound shaping tools on the synth. The Virus C and TI also includes a 3 band EQ
for even more sound shaping flexibility.
Lastly, the Virus has always been 16 parts multitimbral
for multilayered patches and ensemble performances. However, up until the Virus TI, this aspect of the Virus has been severely flawed and is often considered unusable because of the polyphonic limitations of the Virus A, B and C.
The programming methodology for a Virus A is largely the same as that of a Virus TI and so are the bulk of the sounds produced. The additional oscillators, higher polyphony, extra filter type, the EQ and revised control surface and sequencer integration of the TI however, allow for a greater palette of possible sounds over previous revisions although the Virus B and C models have aged well and still compete favourably with recent iterations of analogue modelling synthesizers. There were hardware alterations made to the TI such as the newly added balanced inputs/outputs, 24 bit/96 kHz output and the new sequencer integrated interface.
The Virus TI Snow has been unveiled at Winter NAMM 2008. It is a stripped down version of the TI Desktop. The Snow is patch compatible with the rest of the TI line. It is much smaller, sporting a minimalist interface and utilizes a single DSP chip giving it about half the polyphony and only 4 parts of multitimbral capability.
