Listening to the Factory Sounds
The program memory of the Virus was loaded with sound programs (SINGLE PROGRAMs) and sound
combinations (MULTI PROGRAMs) before it left the factory. To hear the SINGLE PROGRAMs (and gain
an initial impression of the possibilities your new instrument has to offer in terms of sounds), first make
sure your MIDI source is sending on MIDI Channel 1.
Press the SINGLE button. A number, a letter, number and name appear in the display. These indicate
the the MIDI Channel, the current Program Bank (A or B) as well as the number and name of the current
sound program. Now if you play notes you should be able to hear this sound and a ¼ note (the round
dot at the end of the note staff is solid black) should appear in the display every time you press a key and
release a key. If you do not hear a sound but you see a half note (blank note head)  check to see if you
are sending on the wrong MIDI Channel.
Press the VALUE button to call up the 128 single programs of Bank A in sequence. (The VALUE pot is
inactive in this operating mode.) To hear the remaining 128 single programs stored on Bank B, use the
PARAMETER button to activate the other program bank.
Listening to the Multi Programs
The Virus not only has the capability of playing single programs, but also combinations consisting of
more than one sound (MULTI PROGRAMs) simultaneously (MIDI Multi Mode). To call up the
multiprograms, press the MULTI button and select these combination programs via the VALUE button.
The Virus features „only“ 128 multiprograms, so you don’t have to switch back and forth between banks
they way you just did while activating single programs.
The majority of available MULTI PROGRAMs contain sound combinations that are controlled via a single
MIDI channel. In these multiprograms, the sounds involved are allocated side-by-side (split) or on top of
one another (layered) on the keyboard. In other MULTI PROGRAMs, the sounds are divided up over
several MIDI channels to make it easier to work with a sequencer. If you activate a MULTI PROGRAM
and hear a single sound only, then you should control this MULTI PROGRAM via several channels.
Your First Sound Program
If you have never created or changed a sound on a synthesizer, we now have the pleasure of introducing
you to this fascinating process.
Select the single program A127 - START -. Press any key on the connected keyboard. You should hear a
sound that, for lack of better description, is a bit harsh or biting, but above all completely static. It
should start immediately after you press a key and sustain indefinitely for as long as you hold the key
down. As soon as you release the key, the sound should end abruptly. This sound is not designed to be
especially pleasant; it is intended to be as neutral as possible to give you a basis from which you can
begin creating or shaping your own sound.
