CHAPTER 11
The VIRUS and Sequencers

Sequencers are used for recording and playing
back MIDI data i.e. notes and controller infor-
mation. To receive MIDI, the sequencer’s MIDI
Out must be connected to the Virus’ MIDI In.

If you want to use a Virus KC or indigo as your
master keyboard, its MIDI Out must also be
connected to the sequencer’s MIDI In. This con-
nection also makes sense for Virus C or Virus
Rack users: All Virus controls and parameters
can send their data as MIDI signals, which can
be recorded into the sequencer alongside the
note data from the keyboard.

MIDI data can be sent and received via 16
channels per MIDI cable: In Multi mode, the Vi-
rus can play back up to 16 different sounds at
the same time. Sequencers have separate
tracks which can be freely assigned to different
channels, so each sound can be individually ad-
dressed (the MIDI channel of each track should
be set accordingly). If the sequencer has multi-
ple MIDI outputs to allow several devices to
have their own dedicated MIDI line, then the
output port must also be defined for each track. 

The Virus Multi mode consists of 16 Parts, each
of which references a Single sound. The MIDI
channel for each part can be freely assigned. If
you set three Parts to the same MIDI channel,
all three sounds will be played at the same time
when you hit the keyboard. Although layering
can be useful during live concerts, it is more
likely to get in the way when working with a se-
quencer (as sequencers can control each
sound individually). Tip: It is a good idea to set
the MIDI channel of each Part to match its Part
number: Part numbers appear at the top left of
the display, so you will be able to see the cur-
rent MIDI channel at all times.

The Multi program M0 'Sequencer' is already
set up this way, so you can start working with a
sequencer right away. Press the MULTI button

and select the program M0 using the Value but-
tons. The PART buttons are used to scroll
through the 16 Parts. Changes to Virus parame-
ters will affect the currently selected Part only.

MULTI SINGLE mode is perfect for working with
sequencers: Press the MULTI and SINGLE but-
tons at the same time (so that both LEDs light
up). You are still actually in Multi mode, program
M0, but this now appears in a form which gives
you full access to all 16 individual sounds
(switchable using the Part buttons). Just like in
Single mode, you can change the sound with
the VALUE keys, modify it in any way, then save
your work by pressing the STORE button.
Sounds in other Parts are not affected by any of
these actions.

Please note that in Multi mode only a single in-
stance of the Delay/Reverb effect is shared by
all 16 Parts. Changes to Delay/Reverb parame-
ters will therefore affect all sounds involved. The
only parameter which is available for individual
Parts is the effect send. In Multi mode, Delay/
Reverb settings are stored within the Multi pro-
gram, and any such settings in the Single pro-
grams are ignored.

The number of possible tracks in modern se-
quencers is not limited to 16. Also, several
tracks can send data over the same MIDI chan-
nel. This has many practical uses, e.g. record-
ing notes and parameters for the same sound
on separate tracks considerably simplifies fur-
ther editing (see also below: Parameter control
via MIDI).

The Virus KC and indigo keyboards always
send MIDI data over the channel defined in the
current Part. If the Virus keyboard is being used
as the master keyboard for a modern sequenc-
er, the channel setting makes no difference
here: The sequencer ignores MIDI channel in-
formation from the keyboard, and sends data
