ACCESS VIRUS B
RACK "CLASSIC" (2000)

 

Rackmount version from the B series evoution from previous Virus model A with less polyphony and 1 less digital oscillator at lower budget price.

 

tech
structure

info RACKMOUNT main panel features a 16 x 2 lines display, 5 knobs, 16 leds and 12 buttons.

Front panel terminal connectors:
- audio signal inputs.
Back panel terminal connectors:
- audio inputs
- 2 main outs + 2 AUX
- Midi interface.

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


 

edit VOICE physical-modeling DSP core generates 16 voices polyphony at 24 Bit resolution and converters at 18 bits. The Virus synthesis is a mix of virtual analog modeling and short PCM waveforms, these are the Harmonic Spectral Waveshapes.
STRUCTURE a voice is composed by 2 oscillators + 1 suboscillator + 1 noise source (3 colors : white, pink or highpass)

fx PERFORMANCE system handles 16 parts with individual settings:
- velocity assignable to FM, panning, osc shape and width
- variable portamento time
- 4 mono playmodes with glide
- 2 voices stack with detune
- Midi channel
- key zone
- transpose
- pitch detune
- analog out / volume
- note priority
- FX amount
- knobs can be assigned to any parameters.

edit ENVELOPE 2 EGS:
- EG1 AMP: 4 segments + 1 time
- EG2 filter: 4 segments + 1 time with EG polarity.
TIP: the "Punch" option boost the attack on the EG1.

 

EG




filterFILTER
section features 2 filters (-12 dB each) can be combined in 2 serials (SER 4 / SER 6) , 1 parallel (PAR 4) or directly to independent mode (SPLIT) .
Both filters feature 4 different models:
- lowpass
- highpass
- bandpass
- bandstop
The saturation parameters emulates a tube distortion.

 


lfo LFO
up to 3 delayed modulators:


  LFO1 LFO2 LFO3

midi
ARPEGGIATOR each part features an arpeggiator with latch, gate, swing , octave range and 6 modes/directions: up, down, up/down, random, "as played" and "chords".
SYNC arpeggiator, delay and LFO can be sync internally from 63 to 190 BPM (17 time dividers) or slaved to external Midi clock

 


fx EFFECTS
there are 34 effects split in 4 categories:
- master : delay and reverb
- chorus
- analogue boost
- 32 bands-vocoder.
External signals can be processed by the analog inputs.

 


edit MEMORY :
- 256 patch rom (first OS)
- 256 patch ram (first OS)
- 1024 in updated version (factory songs are deleted)
Battery replacement: Memory system works with a 3V CR-2032 on the board.

REVIEW "Something between A and B, with less features but THE classic VIRUS sound. People sell it for peanuts: if you don't mind for the limited interface, then go for it!"
