ACCESS VIRUS A (1997)


The first of the famous VIRUS synthesizers family started at the end of the nineties.

full of knobs!
virus A technical info

info MODULE with optional rackmount ears.
The main panel features a 2 x 16 lines display, 27 buttons and 32 knobs with relative or absolute position mode.

Back panel terminal connectors:
- 3 stereo outputs
- 1 stereo or 2 independent mono inputs
- Midi IN and OUT that can be also switched to THRU
- headphones using first left out.

acPower supply is external PSU - 12 VDC 1A (+ polarity

 

 

edit VOICE physical-modeling DSP core generates 12 voices polyphony at 20 Bit resolution.
The synthesis is a mix of virtual analog modeling and short PCM waveforms - these are the Harmonic Waveshapes.
A voice is composed by 2 oscillators + 1 suboscillator + 1 noise source:

Wave sync - 1>2 -
FM - 1>2 -




filterFILTER
2 filters (-12 dB each) can be combined in 2 serial, 1 parallel or directly to independent mode. Both filters feature 4 different models:
- lowpass
- highpass
- bandpass
- bandstop.
The Keyfollower option and filter saturation (it basically emulates a vacuum tube distortion).

 

EG

 



adsr ENVELOPE
2 EGs:
- EG1 AMP: 4 segments + 1 time
- EG2 filter: 4 segments + 1 time with possible EG inversion.

 



fx
PERFORMANCE system handles 16 parts with individual settings:
- velocity assigned to FM, pan, osc shape and width
- variable portamento time
- 4 different mono playmodes
- 2 voices stack (with detune)
- Midi channel assign
- key zone assign
- note transpose
- pitch detune
- analog out / volume
- note priority
- FX amount
MIDI full Control Change implementation + full exclusive systems TIP: there are 2 freely assignable knobs to any Midi CC#.


lfo LFO up to 3 delayed modulators:

MATRIX like a modular, the Virus handles 3 internal routings or virtual patchcords that connect a modulation source to a destination.
Here's a simplified table:

fx EFFECTS
there are 2 digital FX onboard:
- chorus: with rate, depth, delay, feedback and LFO shape
- delay: with rate, time, modulation LFO and feedback.


 

midi ARPEGGIATOR simple function with latch and 4 directions: up / down / up-downd / as played. Virus arpeggiator and LFO1-LFO2 can be sync internally from 63 to 190 BPM (there are 17 time dividers) or slaved to external Midi clock.
