1. Short description
2. Hardware / Connections
The module generates maximum four part chords within a range of maximum 9 octaves. To your
disposal are 32 chords in 2 banks which can be put additionally into the first or second inver-
sion. As a further variation the respective second note of the set chord (CV gate 2) can be trans-
posed down about one octave. So in total there are 192 chords to your disposal.
The module can be used for the generation of 2 -note, 3-note or 4-note chords plus a fifth arpeg-
gio voice.You have 3 operating modes for manual calibrations plus quantized or not quantized
control via CV inputs.
The notes of the chord can be spread sequentially via the separate arpeggio output. Via the CV
input the arpeggio can be spread or be put into scale mode (quantizer).
The arpeggio can be played in all three modes.

2.1 Connection to the modular system (Doepfer Bus)
The module is delivered with a connected
ribbon cable for the Doepfer bus. The red
lead marks -12 volt. Connecting the module
please note the right polarity!
If the module is poled accidentally wrong
safety diodes avoid the immediate destruc-
tion of the module but further damages can-
not be excepted.
So please pay attention: Check the connec-
tion various times before switching on!
Attention: Please check the correct connec-
tion several times before switching-on the
module!
PLease note!!
The miniature precision ruler at the board is
adjusted exactly to the correct justification of
the reference voltage for the AD and DA con-
verter. It must not be readjusted! The modu-
le would not more run precisely. A probably to
big voltage could also damage the circuits.

3. FUNCTIONS
3.1 Mode
Please choose one of the three modes with the switch:
MANUALLY:
Chords are set manually at the module.
In this mode fundamental note, octave, chord and inversion are set manually. A changing of the
chord (chord, inversion) is displayed by blinking of the LEDs.
The adoption of the new adjusted chord happens with the OK switch. Keynote, octave and 2nd
tone will be adopted directly without affirmation.
The inputs CHORD, TRANSPOSE and TRIGGER are inactiv.
2nd tone can be operated externally and adopts a possibly previous changing of the chord.
QUANT:
The output voltages of the chords follow the voltage at the transpose CV input starting from 1 volt
in halftone steps (quantized).
In this mode too you can put manually keynote, octave, chord and inversion. Additionally the
parameters can be effected also via CV input for CHORD and TRANSPOSE (starting from 1
volt). A changing of the chord is indicated by blinking LEDs.
The adoption of the new adjusted chord happens with OK switch, a positive trigger-in-impuls or
the changing of "2nd tone".
Starting from 1 volt at the transpose input the keynote can be adjusted via CV. Then the octave
will be added to the adjusted octave of the octave switch.
Keynote, octave and 2nd tone will be adopted immediately.
DIRECTLY:
The output voltages of the chords follow directly the voltage at transpose CV input (not quanti-
zed).
In this mode the input voltage is not quantized but the tone pitch of the chord follows directly the
input voltage. The tone key, tone pitch and octave
are determined directly by the impressed voltage.
You adjust the chord here the same way as in mode QUANT.

Button <> changes between the two chord banks
Button up/down Change between the chords of the bank upwards or downwards
Button OK Adopts the choosen chord

3.3 Chord inversions
With the push button you can set the inversion of a chord:
ROOT: basic position
1st: first inversion
2nd: second inversion
ROOT:
In basic position the chord starts with the root as low-pitched note on the first CV-output.
1st:
The first inversion transposes the root about one octave up. The chord removes and starts now
with the second note as the lowest note.
2nd:
The second inversion additionally transposes the second note about one octave up. The chord
removes again and now starts with the third note as the lowest note.
The inversions cannot be changed directly via seperate CV input. But this you can do via
CHORD CV input, because the chords with their inversions are arranged
one after the other in the CV list (see schedule of the chords).

3.4 Second note ( 2ndTone)
3.5 Generate chord via CV input (incl. position)
The second note of the chord can be transposed down about one octave. This offers a further
chord variation.
In contrast to the inversions here at the CV outputs the chord doesn`t remove.
This affects also the arpeggio: The notes don`t go down equally any more (octave step in
second note).
The transposition of the second note down is indicated by LED.
The shifting can also happen via positive impuls of trigger at the 2nd note input.
In mode QUANT/DIRECTLY you can set the chord via CV input CHORD. Assumed is an ave-
rage input voltage about 5 volt:
Chords at the bank left:
Starting with MAJOR in halftone steps down you have Root, 1. inversion and 2. inversion in
paralell.
Chords at the bank right:
Starting with MINOR in halftone steps up you have Root, 1. inversion and 2. inversion in para-
lell.
3.6 Keynote/ octave via CV input
In mode QUANT / DIRECTLY you can set root and additional octaves via CV input TRANSPOSE.

4. ARPEGGIATOR
The CLOCK sets the notes of the chord serially on the arpeggiator output (depending on the
playmode).
You can set the clock manually with the key A-CLOCK or automatically with external clock. The
playmode is set with the key A-DIR or automatically with clock impulse via A-DIR input.
The arpeggiator has four playmodes:
UP - LED up on - direction forward (loop=4 steps)
DOWN - LED down on - direction backwards (loop=4 steps)
UPDOWN - LEDs up+down on - direction alternated forward/backwards (loop=6steps)
RANDOM - LEDs up+down off - direction randomized
You choose the CV of the arpeggio output only by clock input. That means a new chord choise
starts with the next arpeggio clock at the arpeggio output.
You can use the arpeggiator in all three playmodes likewise.
The arpeggio can be spread independently of the chord. You can select the spreading with dif-
ferent voltages at the CV-INPUT jack:
0..2 volt and 4..5 volt no Spreading (normal output):
The chord is played in the original tone pitch.
3..4 volt spreading first step:
The chord is spread up about 1 octave.
(the chord at the outputs 1 to 4 stays the same)
2..3 volt spreading second step:
The chord is spread up about two octaves.
(the chord at the outputs 1 to 4 stays the same)

Arpeggio spreading second step:

The arpeggiator can also work as a quantizer. Then you use the choosen chord as scale. The
keynote is determined by the keytone. The scales are limited on the 4 tones
of the chord.
The scalemode cannot be played manually but gets active starting from a voltage of 5 volt at the
CV input "INPUT". Then the ARP-DIR-LED´s are off.
In this mode the arpeggiator doesn´t play the chord sequentially, but quantizes the input volta-
ge at "INPUT" from 5 volt into a scale, which is determined by the chord as scale and the key-
tone as keynote. A positive trigger impuls at A-CLOCK input makes the quantization.
Chromatical keytone:
If you choose one of the two chords "OCT RANDOM" or "RANDOM" the chromatical scale (half-
tone steps) is set automatically.
At all other chords the notes of the chord correlate with the scale (see schedule).
The 5 CV outputs are set on the 1v/ octave characteristic (via hardware). To compensate varia-
tions of connected VCO`s, for each output you can separately adjust in small steps the
1v/octave spreading or an offset.
Start the menu: The unit has to be set in normal function! The menu can be set in all playmo-
des: Press button OK and then press button <>.
Choosing the CV output you want to calibrate:
The 5 yellow LEDs up (UP, DOWN, ROOT, 1st, 2nd) indicate the choosen CV output 1 to 5 from
left to right. You choose with both of the push buttons (down to them) to the right or left.
Choose voltage fot note and octave:
Keynote with rotary switch, switches OCT and MODE set the octave:
MANUALLY: with switch OCT: octaves 1, 2, 3
QUANT: with switch OCT: octaves 4, 5, 6
DIRECTLY: with switch OCT: octaves 7, 8, 9
>>A changing of the voltage influences only the just choosen CV output.
Change between 1v/oct or offset setting and calibration:
With button<> you can change between 1v/oct (left chord LED on) or offset calibration (right
chord LED on).
You can change the value starting from an average value seven steps up or down. The avera-
ge value is on ADD 9 LED.
With the curser-down-button into direction random you can enlarge the spreading (or offset).
With the curser-up-button into direction major you can reduce it.
Finish of calibration- save settings:
When the calibration is finished, press the button OK. Then you will change into normal mode
and the set values don`t get lost but saved permanently in the
internal EEPROM. At a reboot they are reloaded automatically.
