A. Introduction
With the Wersimatic CX 2 Rhythm & Accompaniment unit (hereafter known simply as
the CX 2), you have the finest device of its kind available today. Not only does the CX 2
have a fantastic selection of instruments and patterns, but you can also program your own
rhythms and accompaniments.
The purpose of this manual is to help you learn the CX 2 and all its capabilities, so you
can play with a background orchestra that is the envy of the professionals.
We will use a simplified approach, showing you the purpose of each panel control and
how you, may use it to get the desired effect. The control panel, with number-coded
switches for easy reference, is shown throughout the manual, so you are never far away
from a quick check on what we are calling for. Once you have learned how to use the
CX2's basic functions, you can move on to programming, in which you get to use your
creativity in composing your own rhythms and accompaniments. For programming, of
course, you need the optional "Instrument and Programming" panel (standard in the
freestanding CX 2 and Galaxy). The good news about programming the CX 2 is that you
don't have to be a computer expert to do it!
The best way to learn the CX 2 is to have one in front of you so you can try the various
functions as you learn about them. The instructions given here apply regardless of the
organ model your CX 2 is in. There are a few slight differences in using the freestanding
CX 2, but they are so noted in the text.

B. Operating Instructions
You will find that the CX 2 is quite simple to operate, once you acquaint yourself with its
controls. And, since all CX 2 functions are initiated from the control panel, we'll begin
our operating instructions by introducing you to the various switches and controls on the
main panel. (There is also an instrument and programming panel which we will get into
later.)
Hopefully, you are in front of a CX 2 unit as you are reading this manual. You can learn
faster by actually trying the functions as you read about them. Refer also to the line
drawings of the panel found throughout this manual. To make it easy for you to locate the
switches as they are called for, we have numbered each switch in the drawing, and refer
to the switch both by title and number in the text; ex.: Start/Stop (36).
Looking at the panel, you will notice that the switches are color-keyed. This also will
make using the CX 2 easier, since you will eventually be able to locate a switch more
quickly, once you recognize it by color.
The switches are the momentary type (Digitast); that is, when you depress a switch, it
doesn't lock, but spring-returns. Depressing a switch will initiate a function, as indicated
by a light-emitting diode (hereafter known as LED), which glows when the function is
active. Depressing the switch again stops the function (LED goes out).
In the lower left-hand corner of the panel you will see some conventional-looking rotary
controls. The "Tempo" controls, of course, permit you to adjust the tempo of your rhythm
over a wide range; Tempo -the upper knob -is a coarse adjustment; Fine Tempo -the
outer ring -permits a closer adjustment. Volume is self-explanatory. The Balance
control allows you to control the volumes of the rhythm and accompaniment with relation
to each other -turn it clockwise and the rhythm instruments get louder relative to the
accompaniment instruments; turn it counterclockwise and the reverse is true.
In the upper right-hand corner of the panel there is an LED display Tempo/Tuning that
lights up in red numbers (like a calculator) when you turn on the unit. The numbers that
appear there will have meaning as you go through the CX 2's functions.
There is no better way to learn to do something than by doing it, so let's turn on the CX
2and start learning.
If your CX 2 is in an organ, it will turn on with the organ. The free-standing unit has a
power switch on the rear panel.
At turn-on, the LED display Tempo/Tuning will show the frequency of the organ's master
generator, based on the note middle A, or 440Hz. This, of course, tells you if the organ is
in tune; you should set the reading to 440 by varying the organ's Master Pitch control.
(Disregard this for the free-standing unit, since it is an independent unit and has no
separate "master

generator" to set) After about 30 seconds, the 440 indication will disappear and be
replaced by the tempo rate. You can restore the tuning frequency by depressing the
switch Reset (9).
You will note that the following switches are active (LED lit) at turn-on:
Reg/Play (5)
Acc/Mem (8)
Disco (10)
Composer (29)
To start the rhythm, depress Start/Stop (36). You will hear a disco rhythm (provided a
free-programmable composer program is in memory; more about this in the section
"Programming").
If the Tempo/Tuning display was indicating the tuning frequency, you will notice that it
immediately switched to the tempo rate when you pushed Start/Stop (36). This transition
also occurs if a rhythm (switches 10 -17, 20 -27) is selected. You can vary the tempo
rate from 20 to 240 beats per minute via the Tempo controls. Or, if you wish. you can
select a preset "standard" tempo rate for any rhythm you happen to be in by depressing
Tempomat (33). This is a programmable feature; we'll show you how to do it in the
chapter "Programming".
The CX 2 has 64 different rhythm patterns, selectable in four groups of
16 rhythms each. The following instruments comprise the rhythm section:
Bass drum, snare drum, hi hat (long/short), tom tom (low/high), conga
(low/high), cymbal, tambourine, brushes, maracas, cowbells, claves and the
synthesizer drum (synthe-drum).
While we're talking about instruments, it is worthwhile mentioning that the CX 2 is a
stereo device; if you have a stereo organ, it uses both channels; if you have a free-
standing CX 2, you can use it through a stereo amplifier system. Of course, if you have a
monaural organ, the CX 2wilI have been wired for single-channel use. In stereo, you will
notice that some instru-

AM 354-01-405 7
ments predominate in one channel or the other. This gives the sound a remarkable "three-
dimensional" effect. And note this: on intros and breaks, the rhythm "moves" between
channels, adding to the realism.
To select the first group of rhythms, depress Rhythm 1 (18). Now, when you select a
rhythm from switches 10 through 17, the rhythm you hear upon depressing Start/Stop
(36) will be the first variation of that pattern. For example Disco (10) + Rhythm 1(18) =
Disco 1.
Selecting Rhythm 2 (19) gives a second variation (Disco 2) and Rhythm 3 (28) gives a
third variation (Disco 3). Selecting Composer (29) gives a variation dependent on what
has been preprogrammed into the composer memory (more in "Programming").
Selecting from the rhythm groups 1 through 3 (switches 18, 19 and 28) plus the rhythms
of switches 20 through 27 will give one of three distinct rhythms. For example, switch
25 + Rhythm 1(18) = Rock 'n Roll; 25 + Rhythm 2 (19) = Jive; 25 + Rhythm 3 (28) =
Shuffle. Again, what is in the Composer (29) mode depends on what is in the composer
memory.
Select a rhythm (any rhythm) and start the rhythm (switch 36). You will notice a small
blinking indicator in the Tempo/Tuning display. This is the downbeat indicator, which
flashes at the first beat of each measure. This gives you a visual reference to precisely
determine the start of the rhythm.
While the rhythm is running, momentarily depress the switch Intro/Break (35). In the
next measure, you will get a solo drum break, consisting of a sequence of four different
percussion instruments spanning one measure. If you press switch 35 and hold it down,
the drum break will begin immediately and go on as long as you hold the switch down.
Now stop the rhythm (36). You can start the rhythm again by pressing Intro/Break (35),
which will open the sequence with a percussive introduction lasting a measure, after
which the selected rhythm will commence.
Another way to start the rhythm is via the lower manual or pedals. You must first preset
the unit by depressing Syn Start (32). Then when you depress a note on the pedalboard or
lower manual (or the keyboard of the free-standing unit), the rhythm will start. This is
great when you want the rhythm to start during your performance. You then stop the
rhythm the usual way (36).
Aside from the fully automatic functions of the rhythm section, there is also a semi-
automatic function. Depress the switch Man Rh (31) but do not start the rhythm. Strike
keys in the lower manual (or free-standing keyboard) and the snare will sound with each
individual key struck. In legato playing, the snare will sound only with the first key
stroke. The pedals will sound the bass drum and cymbals.
Pressing Start/Stop (36) or Intro/Break (35) cancels the semi-automatic mode and
initiates the selected rhythm. However, pressing Man Rh (31) again will stop the rhythm
and return the unit to semi-automatic mode.
Before we proceed further, you should review the functions introduced here and spend
some time getting to know your rhythm section.

The Rhythm
Instruments
I&P Panel
Roll
Changing the
Instruments
At this point, let's look at the Instrument & Programming Panel (hereafter known as the
I&P panel).
Select a rhythm and start the rhythm unit. With switch Reg/Play (5) active (LED lit), you
will see the switch has the name of one of the rhythm instruments printed (in orange) near
it. Each time an LED flashes on, the instrument for that switch is active. By observing the
LED's, you can see exactly which instruments comprise any rhythm and when they are
active.
If you press an instrument switch, that instrument will sound, giving you the capability of
a solo percussive performance from the I&P panel. And here's a bonus: If you depress
and hold Snare loud (P3) and Snare soft (P4) simultaneously, you'll get a snare roll,
somewhat faster than a 1/16th rate. If you activate Roll (4) -LED on -on the main panel,
you can roll any instrument on the I&P panel at a 1/16th rate by holding its switch down.
If Roll (4) is active and you press P3/P4, the result is a unique tempo-variant-accentuated
roll. . . well, you'll have to try it; words can't describe it.
Your can change the instrumental makeup of your rhythm by switching out certain
instruments. To do this, turn off Reg/Play (5) on the main control panel (LED off). All
the LED's on the I&P panel will light. When you press an instrument switch, its LED will
turn off and that instrument will be inactive. Press the switch again and the instrument
will be restored. The bass drum or snare can be deactivated by pushing either "+" or "-"
for either instrument.

It is possible to mix rhythms in the CX 2. The switch Add/Erase (3) allows you to do this.
For example, suppose you wish to mix the rhythms March 1 and Waltz. Here's how:
Example 1: Mixing Rhythms
Push switch: Function:
Reset (9) Resets CX1
March (17) Rhythm select March
Rhythm 1(18) Group Select
Start/Stop (36) Starts rhythm
Add/Erase (3) Add next selected rhythm
Waltz (27)Rhythm select Waltz
The result is a March-Waltz.
Note: If you activate Tempomat (33), the tempo will be that of the march. If
you wish a waltz tempo; you must select Waltz first, then add March.
You can also mix rhythms of different groups:
Reset (9)
March (17)
Rhythm 3 (28)
Start/Stop (36)
Add/Erase (3)
Rhythm 1(18
Waltz (27)
Or you can mix all the rhythms of the same select switch:
Reset (9)
Rhythm 1(18)
Swing (26)
Start/Stop (36)
Add/Erase (3)
Rhythm 2 (19)
Foxtrot (26)
Add/Erase (3)
Rhythm 3 (28)
Swing Fox (26)
If you push the rhythm switch (26), the rhythm will revert to group 1 -Swing. If
you push one of the group switches (18, 19, 28), the rhythm will revert to that
group.
Before we move on, we want to remind you that 24 instruments comprise the CX 2
rhythm section. A live drummer would have his hands (and feet) working overtime to
keep that many instruments going

The Accompaniment
Section
LM Accompaniment
Range
The accompaniment section of the CX 2 is a backup orchestra consisting of 13
instruments assigned to three parts:
Bass: Tuba, bass guitar, synthesizer bass;
Chords: Strings, piano, guitar, wah wah guitar, organ;
Melody (arpeggio): Brass, clarinet, strings, bells, banjo.
The accompaniment is activated via the switch Accomp (30) and is compatible with the
selected rhythm pattern.
As a first step in getting to know your accompaniment section, depress Accomp (30), but
do not start the rhythm. The tuning frequency of the accompaniment generator will
appear on the Tempo/Tuning display. (This is also true of the free-standing CX 2, which,
while it shows no master frequency indication at turn-on, will show the frequency of its
internal generator when 30 is pressed.) If the unit has been on, depress Reset (9), then
Accomp (30) to see the tuning frequency.
The accompaniment frequency should be close to that of the organ master generator, or
440 Hz. The frequency should be pre-adjusted, so you should be ready to go. The organ
frequency can be set by the organ's master pitch control. Compare the two frequencies by
turning Accomp (30) on and off (on = accompaniment; off = organ). For the free-
standing unit, you can set the accompaniment to the pitch of another instrument with the
Pitch adjustment on the front panel, under the I&P switches.
The frequencies involved here can be set to within tenths of a hertz. Don't worry about
small differences, though; a 1 Hz difference is only 1/25 of a half-tone step. In fact, a
little dissonance may be desirable, as in the "tempered" effect of a piano note when the
three strings are slightly out of tune with each other. Let your ear be the final judge!
Now you're ready to start the accompaniment section.
Select one of the rhythms and depress Start/Stop (36). The rhythm will
start. Push Accomp (30) -LED on.
