Access Virus Rack XL User Manual page 13

The LFOs feature 6 continuous variable wave-
shapes each, including a triangle with variable
symmetry and infinitely variable aperiodic oscil-
lations for random variation of the controlled
parameters. The LFOs are capable of poly-
phonic as well as monophonic oscillation. In
other words, if several voices are active, the
LFOs can run independently or in sync. A
number of keyboard trigger options enable you
start LFO waveshapes with variable phase
lengths at the beginning of a note and/or to cy-
cle once only, like an envelope.
Next to the numerous "hard-wired" or fixed
modulation configurations, you can assign six
modulation sources to up to nine different mod-
ulation destinations via the Modulation Matrix.
For your modulation sources, you have LFOs,
velocity, the pitch bender, aftertouch, the mod-
ulation wheel, numerous MIDI controllers and
other sources to chose from. For your modula-
tion destinations, you can select any sound pa-
rameter of the Virus that is conducive to being
remote controlled.
Up to 16 arpeggiators are available in MULTI
mode. These give you countless options for
creating arpeggios, which can also be synced
up to MIDI clock.
Sounds and effects are patched out via four au-
dio outputs which of course can also be used to
route two stereo signals out.
The Virus rack XL comes with a powerful soft-
ware editor for PC and Macintosh. It lets you
edit and manage sounds on a large-scale user
interface. You can access every sound parame-
ter of the Virus rack XL directly via mouse click.
When you edit a parameter, the Virus will render
the changes immediately in real time. Accord-
ingly, every parameter change that you make
using the encoder knobs (those knobs without
left and right control range limits) on the Virus
rack XL appears immediately on the screen. In-
cidentally, this editor is based on Emagic's pop-
ular SoundDiver.
In all modesty, we are especially proud of a fea-
ture we developed called Adaptive Parameter
Smoothing. For the first time in the history of
synthesizers equipped with memories, you can
manipulate a knob or control feature without an
audible step or increment. In other words, the
sound does not change abruptly but SEAM-
LESSLY. No more zipper noises! The Virus re-
sponds just as smoothly as analog synthesizers
did prior to the introduction of digital sound
storage.
And users of contemporary software sequenc-
ers will appreciate the fact that the Virus sends
all sound shaping commands immediately in
the form of MIDI Controller or Poly Pressure da-
ta (and of course accepts all of the correspond-
ing Controller and SysEx messages). This
feature lets you dynamically control the Virus
and all its functions via computer.
Although far from complete, the features listed
above give you some indication that you now
own an exceptionally versatile, high-quality mu-
sical instrument that will give you plenty of joy
for years to come. We certainly hope you can
fully exploit the enormous potential of this fine
instrument.
Have fun and enjoy!
