INTRODUCTION
INTRODUCTION
WELCOME TO THE DX You have just purchased a most powerful tool for composition and performance. The
Oberheim DX Programmable Digital Drum Machine represents the latest in the Ober-
heim line of drum computers. The DX has been designed with the idea of giving you
better sound, and better control of it, than has ben previously available in a drum box
at a more economical price.
The DX generates the sounds of real drums. Actual drum recordings have been digi-
tized, stored in computer memory, and are avalable at the touch of a button. A drum
beat can be recorded in real time at any spee, remembereq, and edited to make any
beat of any length, tempo, or style-in short, any drum beat that you hear in your head
you can create on the Ox. After you have created your drum beats, you can save them
on tape for future use. Of course, the DX has a battery to keep the memory on when
the power is oft.
The DX has a MIDllntertace, which enables interconnections with other equipment
such as sequencers, keyboards, drum pads, and other drum machines.
The DX operates like a tape recorder: press RECORD + PLAY to Record your
rhythms; then press PLAY to hear It back. But there s more to it than that. There are
features incorporated into the OX that actually give you more control over your music
than a tape recorder allows. We recommend that you familiarize yourself with these
features in order to get the most out of your DX.
The OX can make most any drum beat that an acoustic drummer can create. In fact.
this rhythmic flexibility of the DX creates a new dilemma for the user. exactly WHAT
makes a good drum beat? It is not within the scope of this manual to try to answer this
question, but if you re not a drummer already. we strongty suggest spending some
time listening and studying the rhythms of your favorite music. Listen to where the
notes are and where they re NOT where the accents are, when the beat is pushed or
swung. If your drum machine sounds cold and robot-like, fl's beause you ve pro-
grammed it that way. It takes a good sense of timing to create rhythms that really
breathe.
Experiment! You ll never know what you ll discover.

Selecting A Sequence
The DX can store up to 100 drum sequences. numbered 00 thru 99. Select one by
pressing two numbers, or one of the arrow buttons. The display will show you which
sequence you have selected.
Playing A Sequence
Press PLAY. The sequence will play over and over until you press STOP. You can also
select another sequence while playing ahd the OX wil play it immediately after the first
sequence has finished.
Real Time Recording
There are two ways to record on the OX: REAL TIME and SINGLE STEP. In REAL
TIME. the sequence plays over and over and you simply press the buttons where you
want the drums to sound. In SINGLE STEP, the sequence advances one beat each
time you press either of the arrow buttons, which allows you to record your drum beat
slowly. The REAL TIME mode of recording is expiained here. The SINGLE STEP mode
of recording is explained in the section entitled STEP.

Press and hold RECORD and then press PLAY. The Metronome will click in eighth
notes and the OX wil record over and over on two measures. In RECORD, the OX
does not ERASE, so you can build your drum beat as it loops over, playing the cymbal
first, the bass drum, then the snare, etc., unti you are finished. The OX wil also Quan-
tize or raun!= off, your playing. When you have finished recording, press STOP.
You can add more parts to the sequence simply by recording once again. Erasing is a
separate process.
REMEMBER: The OX will not RECORD if the MEMORY PROTECT switch on the
rear panel is ON.

GETTING AROUND
Erasing A Sequence
If you have made a mistake, or would like to record over again, press and hold ERASE
and while holding ERASE press RECORD. The current sequence will be erased, and
you can record again from scratch. The OX will "beep" when the erasure actually
takes place. The volume of the beep is controlled by the metronome volume control.

Tempo
The DX is normally set to a tempo of 80 Beats per Minute, but can be varied within a
range of 25 to 250 Beats per Minute. You can change the tempo at any time by enter-
ing the tempo mode. Press TEMPO. The Tempo button will light and display wil show
the tempo currently selected. You can change the tempo by pressing the buttons with
the arrows to increase or decrease the tempo, or you can enter the desired Seats per
Minute on the keypad (3 digits). To exit the tempo mode press TEMPO once again.
To program the tempo in a sequence press TEMPO while in Record, set to the desired
speed and pres TEMPO once again to exit. Whenever that sequence is recalled, the
DX will recall the tempo as well. You can change the tempo at any time, but the pro-
grammed tempo will be changed only when the tempo Is set in record.
. NOTE: Not every tempo marking between 25 and 250 Beats per Minute can be
played. Near the high end of this range the tempo steps are larger than one Beat per
Minute. If you enter a tempo which cannot be played, the DX will play the nearest valid
tempo to the one which you entered. Also. if you try to RECORD an invalid tempo, the
DX will actually record the nearest valid one.
If you enter a number that is out of the tempo range. the display will flash. You must set
the tempo to be in range before you can eXIT from the tempo mode.
The arrow buttons will always step between valid tempos.
Length
A sequence can be any length from 1 to 99 bars. The DX sets a length of 2 bars for
each sequence unless you set it differently. To change the length of the current
sequence press LENGTH. Then, using the arrow buttons or the number keys, choose
the new length. The display will flash. The new length can be entered in memory by
pressing the LENGTH key again. If any other key is pressed, the length will not
change.
If you have recorded a sequence and then shorten the length, you wil lose the bars
you have cut. If you lengthen a sequence you have recorded, rests wil appear at the
end.
LENGTH sets the number of bars within a seuence. The length of each bar is set by
SIGNATURE.
REMEMBER: If the MEMORY PROTECT switch is on, the Length of a sequence
cannot be changed, although the Length can be displayed.

"" - . . . .. .. .......... -
SONGS One prominent feature of music is that it is organized into sections that repeat and
alternate with each other. The Song Mode allows you to record each section of a
piece as a separate sequence and then combine sequences into a complete
composition.
A Song is a listing of sequences. The DX contains 50 Songs, numbered 00 thru 49, in
addition to the 100 sequences. Unlike a sequence, a song does not remember the
notes, only the order of sequences thaf you wish to play. There can be as many as 255
sequences contained with!n a song, and each sequence within a song can have its
own tempo, length, or time signature. Songs make more efficient use of the OX
memory. In fact, playing three sequences in a song uses as. much memory space as a
single note in a sequence.
Selecting A Song
To enter the song mode, press SONG. The Song button wiH light and the DX will select
the song previously selected. To select a different Song simply press the number of
the desired Song.
To go back to Sequence mode, press SONG again.
Playing A Song
Once the desired song has been selected, press PLAY and the selected song wil play
from beginning to end and then stop.
As the song plays through the different sequences in it. the sequence number on the
display wil change to reflect the actual sequence presently being played. Each
sequence in the song is given an ascending PART number that reflects its order in the
song.
Creating A Song
Creating a song is different than recording a sequence. because you are not playing
any notes, just making a list of sequences.
To create a song press EDIT (while in Song mode- both SONG and EDiT buttons
should be lit.). Once you enter SONG EDIT mode, the OX wil ask you to select the
sequences that will make up the song: the "Song List:.
The arrow buttons can be used to "rewind" and "fast forward" through the song list to
get to a particular part.

There are four editing commands:
ADD: If the display shows the end of a song list (only a part number displayed on the
left side - right side blank), you can add a seuence to the end of the song byenter-
ing the desired sequence number. If a song list is empty, the first part wil be blank.
REPLACE: You can REPLACE any sequence currently displayed with another simply
by entering the new sequence number.
INSERT: By pressing RECORD and EDIT, the DX wil insert Sequence 00 into the
song list before the sequence previously displayed. You can then REPLACE
Sequence 00 with the desired sequence by entering its number.
ERASE: By pressing ERASE and EDIT, the DX will remove the displayed sequence
from the song list.
To play the song you have just created, press PLAY.
. NOTE: A song can have up to 255 parts in it. However, only the lowest two digits are
shown in the display.
REMEMBER: The DX will not EDIT a SONG if the MEMORY PROTECT switch on
the rear panel is ON.
Erasing A Song
You can erase an entire song while in Song mode by holding ERASE and pressing
RECORD. Individual sequences within the song list can be removed in the Song Edit
mode (see Creating A Song).

The OX contains six sets of voices. Each voice has three variations, and some of the
voices contain two completely different sounds. Only one voice variation can be
played at a time. The sound of each voice is contained on one or several memory
chips.
SOUNDS The OX comes from the factory with the following voices and these variations:
BASS / Bass drum, with three volume levels.
SNARE / Snare drum, with three volume levels.
HI-HAT / A hihat, with a closed and an accented sound, plus a longer "open sound.
TOMS / Toms with three pitches.
CYMBALS / A Ride cymbal, with two volumes, plus a Crash cymbal.
PERC / Two sounds: a shaker with accent, plus hand claps.
Tuning
The pitch of each of the voices can be tuned up or down half an octave by adjusting
the pitch controls located on the rear panel of the DX.
Changing Sounds
The OX drum sounds are contained on computer memory chips. By changing the
chips, you can customize your OX to your specific application.

:)UfHI:)T/CATION
SOPHISTICA TlON
The OX incorporates several functions that change the time and feel of the machine
and enable programming one beat at a time. Utiizing them wil increase your rhythmic
possibilities and make gramming faster and easier.
QUANTIZE Quantizing automatically corrects your playing to the nearest beat. The quantizing
value also establishes the smallest beat that can be recorded. and is used for estab-
lishing the value of a "Beat" as used in STEP and SWING.
The DX is normally set to quantize to a sixteenth note. To change the quantizing, press
QUANTIZE. The display wil show the value of quantizing c rrently set. You can now
enter the note value that the DX wil round off to by using the arrows to increase or
decrease the number in the display.
Quantize is a record function. That is. it only corrects what you are recording. This
enables you to record over and over on the same sequence in different quantize
modes. Quantizing is also independent of the metronome. It is possible to quantize to
the nearest quarter note, even though the metronome is clicking in sixteenth notes.
The Quantize value can be changed while in Record or Play as ell.
QUANTI ZE euens out your playing:
Quant = 1/16 . 2 . . . 3 . 4 .
QUANTI ZED...
SWING Swing is similar to Quantize in that it corrects the timing of your recordings. However
Swing wil alter the time so that the first half of the t1t gets more than half of the time,
creating a "shuffle" feel.
Press SWING. The display will show the current swing value which is normally set to
50% (the first half of the beat gets 50% of the time). To change the swing value, press
the arrows to increase or decrease the percentage. Swing is a Record function. That
, it wil record your playing corrected to the swing value you have selected.
You can apply the Swing function while Quantizing to any value from 1-2 to 1-48. If
Quantize is set to 1- , 1- , or OFF, the DX will "beep" and the QUANTIZE button
will light.

METRONOME The Metronome can be set to click in any note value between half-notes and one-
hundred-ninety-second-notes (48 clicks per 1/4 note). The Metronome defaults to
eighth notes and varies in speed according to the tempo. A dot representing the Met-
ronome pulse also appears on the display.
To change the Metronome, press SIGNATURE. The current Metronome click value wil
appear on the display. The click value can be set to any standard note value by using
the arrows buttons to increase or decrease the number in the display.

After you have set the desired click value, you may exit by pressing STOP; or you may

The Click Value can be changed in STOP, PLAY, or RECORD, in Sequence or Song
modes.
The Metronome is heard through the mixed outputs of the OX while In Record. The
click is accented on each downbeat. The Metronome also app ars at the CLICK OUT
jack on the rear panel in Record and Play and can be routed through an external
mixer. The output of the CLICK OUT jack is not accented and has been designed to
be used as a clock source for other devices, such as arpeggiators.
The OX can be set to countdown four metronome clicks before recording. See EDIT

The Metronome can also be programmed to click only when a drum or combination of
drums is played. This is useful for clocking other devices. such as the arpeggiator on
the 08-8, in uneven patterns. See Programmable Metronome blick In the GOODIES
section.

SIGNATURE The SIGNATURE buttn is used to change the time s!gnature.
The OX can be set to play in most any lime signature. There can be between 1 and 99
beats per measure, and between a half note and 1/192 note can receive one beat.
Press SIGNATURE. The current Metronome value will appear on the display. (see
METRONOME. above).
Pres SIGNATURE once more. Now the current time signature will appear on the dis-
play, and the beats per measure wil flash. You can use the arrows to increase or
decrease the beats per measure or you can enter the desired value with the keypad.
Press SIGNATURE again, and the beat value will now flash. You can use the arrow
buttons to increase or decrease the beat value to any common increment.
. NOTE: Changing the time signature of a programmed sequence causes the length
of the seque ce to be redefined in terms of the new time signature. For example if a
sequence of 3 bars of 4/4 (12 quarter notes) is changed to be 3/4. the length will be
recalculated to become 4 bars of 3/4 (12 quarter notes). Changing the time signature
can also create sequences that are longer than 99 bars.

SOPHISTICATION
STEP RECORDING STEP enables Recording a Sequence one step at a time. STEP advances at a rate
determined by the Quantize Value. Normally the Quantize Value is set to a sixteenth
note, but this can be changed-see QUANTIZE. From stop, pressing STEP places you
at the beginning of the sequence. To program a drum on a particular step, press the
desired drum button while that step is displayed. Every time any drum button or either
arrow button is pressed, the sequence advances one step. To record several drums on
one step, hold the RECORD key while pressing the desired drum buttons - this keeps
the DX trom advancing to the next step. To exit step mode. press STEP once again. If
you press STEP while in PLAY or RECORD. the sequence will step from its present
location and go back to play or record when STEP is pressed again.

RECORDING"
Deleting A Sequence
In Stop, holding ERASE while pressing RECORD once erases all notes from the
sequence, but retains length, tempo, and time signature information. At this point you
may re-program the sequence, or use this feature to program blank spaces into songs.
Erasing the sequence second time fe-sets the sequence to the standard default con-
dition of 2 bars. 80 beats per minute, 4/4 time signature. The display will verify that this
has happened by reading: "dEL ;' and will completely remove the sequence from
memory-

display wil show the message "CLr?:' and the ERASE light will be on. Press the
ERASE button and the OX will "beep" and flas all of the lights. This will clear
memory, but wil have no effect on the EDIT PARAMETERS.
