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 Oberheim 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 digitized , 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 robotlike, fl' s beause you ve programmed 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.

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 entering 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 programmed 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.

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.

:)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 establishing 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 .

SWING

QUANTI ZED...

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.

The Metronome can be set to click in any note value between half-notes and onehundred-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 Metronome 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 continue to the time signature by pressing SIGNATURE once more. (See Signature.

The Click Value can be changed in STOP

, PLAY, or RECORD modes.

, in Sequence or Song

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 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

PARAMETER 00.

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 display, 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 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 arrow button is pressed

, the sequence advances either 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 th e 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.

The DX can copy a rhythm from one sequence to another. This is useful to make changes in a rhythm without erasing the original or strting over from scratch.

Press COPY. The display shows the sequence to be copied from (on the left.

) Select the desired Sequence number. Press COpy again and the display wil show the destination Sequence. Select the desired Sequence number. Press COpy a third time and the Copy wil execute.

REMEMBER: The DX will not copy If the MEMORY PROTECT switch on the rear panel is ON.

Appending Sequences

Appending a sequence is similar to copying them except that while the old sequence with the new one, APPEND ADDS

COpy REPLACES the new sequence to the end of the old one. The process is the same as copying a sequence , but hold RECORD while presing COPY the third time to execute.

Appending sequences is useful when the same set of rhythms is to be played over and over , for example in a composition having 3 bars of 4/4 followed by 1 bar of 7/8 as a basic phrase element. By making a sequence of 3 bars of 4/4, another of 1 bar of 7/8

and then appending the 7/8 onto the end of the 4/4

, you have quickly created your basic phase element , which can then be repeted over and over, and combined wrth other sequences as part of a song.

It is possible to append a sequence to itself. This eftectively doubles the length of the sequence. It is also possible to append sequences , one after another , to one sequence. Appended sequences can be of any time signature or length; however

, the tempo and signature of the first part of the seuence will be applied to the rest of the sequence as well. If sequences of different time signatures are appended together

, the length may not equal an exact number of mesures and this wil be refiected by a "

(for Plus) in the length of the sequence. For example, appending a 7/8 sequence to a

4/4 sequence (each of 1 bar length) will cause the display to read:

'" P" because the length of the new sequence is not quite 2 bars of 4/4.

Copying And Appending Songs

Just as one can copy or append a rhythm from one sequence to another

, a song list can be copied or appended from one Song to another.

The procedure is the same as copying or appending sequences done from Song Mode.

except that it must be

REMEMBER: The DX will not copy or append if the MEMORY PROTECT switch on the rear panel is ON.

Free Memory Display

To check the amount of available memory, hold the RECORD button while in Stop

(Sequence or Song Mode). After a moment

, the display wil show the percentage of memory left. The percentage of memory available at a grven time varies depending on the length at the current sequence.

The DX has the capacity to store 2200 events. An event Is any time that

OX voices are playing. If all six voices are playing on every event any or all the

, that adds up to

200 notes that can be stored. There are amongst sequences. In general many ways this capacit can be divided

, it is best to take advantage of the repetitive nature of music by constructing songs from short sequences.

Each part of a song requires one-third as much memory as a single event in a sequence! A song consisting of one bar repeated eight times uses less than one fifth the memory of an eight bar sequence. Therefore

, the most efficient use of memory is achieved by using the SONG mode whenever possible.

Data Check

One of the features of the DX is a data check routine that runs automatically when the unit is turned on and when leaving the Data Storage mode. The data check routine looks at each sequence and song to make sure that it is properly configured in memory.

Bad Sequences can appear in the DX' s memory several ways , by loading a cassette tape with more than 2200 notes from a OMX into a OX

, for example. If there is ilegal information in a sequence, the Data Check routine wil alternately flash the Sequence

Number followed by "dEL?" and the ERASE key will light. If a bad Song is discovered the Song key will light up as well. Press ERASE to delete the bad Sequence. If any other key is pressed the sequence in question will not be deleted

, and it wil look more bad Sequences.

for

After checking all of the sequences and songs the OX wil return to normal operation.

However , if any bad sequences or songs remain in the memory (ones that you declined to delete), the display wil flash " bAd" and the unit wil " beep:'

. Note: Be careful when working with bad sequences (ones that you didn particular , any attempt to alter a bad sequence by Recordin t delete). In g, Erasing, etc. wil almost always cause the DX to crash. See " If Your DX Gets Lost:

Ram Check

Besides the above mentioned Data Check routine, a Ram Check routine is run when the OX is turned on. This routine checks for random data in the memory. Random data of this type can result from a loss of power to the memory, for example. If the data in the memory is bad , the OX wil " beep " and display " bAd;' followed by a "

CLa" message while the ERASE key lights up. Pressing the ERASE key erases everyhing in memory and resets the Edit Parameters to their default values.

If Your DX Gets Lost

Under certain circumstances many computer based products can lock up. In particular . if the message " Err " appears unexpectedly, the OX has gotten lost. In this instance clearing memory will solve the lock up problem

, we STRONGL Y ADVISE

, but you wil lose aU your work too! If this condition ever happens recording your memory on a cassette. Immediately enable cassette mode on the back panel and follow the directions In the CASSETTE INTERFACE section of this manual. When your memory Is safely on cassette , proceed as follows: Press any key and the OX will attempt to proceed. It wil usually succeed , but wil occasionally lock up once again. If it locks up again , even turning the power off and then on again may not help.

When All Else Fails

If your OX does not respond to the above methods of resuscitation , turn the power off.

Then while holding the ERASE key, turn the power on again. This Failsafe Erase Mode wil clear memory and reset the Edit Parameters to t!1eir default values.

When this feature is on , external Timing Sources (EXTERNAL CLOCK

. TAPE SYNC or MIDI) will cause the OX to enter play mode automatically. Because the OX is always looking for a clock signal in this mode

, any signal (even noise) that is present at the

CLOCK IN or FROM TAPE jacks wil place the DX into Play. This may cause occasional false starts. However , the OX wil not false start once the leader tone is detected at the FROM TAPE input. When Auto Start is oft

. the OX wil not detect external signals until you press PLAY. You can only Auto Start from Select Sequence or Select Song modes.

If AUTO START is on , pressing PLAY while stopped wil run the OX from the Internal

Clock. This makes it easy to switch back and forth from internal to external timing.

03 CLOCK OUT RATE

(24 48, 96)

This parameter sets the rate of the EXTERNAL CLOCK OUTPUT, used for slaving other equipment to the OX , such as other Oberheim Drum Machines or Sequencers.

The numbers select the rate of the external clock (pulses per quarter note); set this to

96 for Oberheim equipment.

. NOTE: The Clock Out Rate cannot be faster than the Clock In Rate. For example , if, the Timing Source is set to MIDI (which uses a clock rate of 24 pulses per quarter note), the Clock Out Rate cannot be faster than 24.

04 SET PROGRAMMABLE CLICK

The Metronome Click can be set to click when one or several particular drum buttons are pressed. This allows the click to be used as a programmable trigger output. Holding down any combination of drums first. then pressing RECORD wil cause a Click output in play only when that combination of drums occurs together. The normal steady metronome click wil still be given in record mode. The Click can be set to normal (steady) by hitting RECORD while holding ERASE.

STORAGE

The OX Data Storage feature permits offline backup storage of all of your rhythm programs.

Making backups of your wqrk is something that you should do frequently, with aU your machines. You ll find that keeping copies of your programs wil help speed up your work and eliminate duplication of effort.

What was that rhythm I had before?' No matter , if you ve got it stored. You can load it back into your OX (or anyone else s for that matter) and get on with it.

The OX can store its memory in two ways: via the TAPE jacks onto Cassette , or via

MIDI to another OX or other MIDI device.

TAPE INTERFACE

The DX' s Cassette Interface allows programs to be stored externally on an audio cassette. The tape recorder should have a Line or Aux Input if possible; either Line Level or Speaker Level (Earphone) outputs.

Connection

Connect the Speaker or line Output of your cassette recorder to the jack labeled

FROM TAPE" on the rear of the OX. Connect the "TO TAPE" jack on the rear panel of the OX to the Line or Aux input of your cassette recorder. Connect both cables so that you can monitor the tape through the OX,

Errors

If the DX cannot read the tape properly, the display will read " Err:' for ERRor in data. II this happens , one of the following might be responsibJe:

Tape playback volume. Gelling the OX to read the data properly and reliably generally is a function of the proper playback level. The bet level should be as loud as possible without distortion. Some trial and error is probably necesry, however. Some users find that the cassette intertace reads the data the be when the playback level is tumed all the way up. The data can be distorted to a certain extent and still playback properly. If the playback volume is too low , or If the tape recorder is connected incorrectly, the DX wil not acknowledge the data at all.

The leader tone Is too short. At least three

sends of

the " leader " tone should come between pressing PLAY and the rough sound of the memory information. Generally, if the leader tone is too short, the DX wil immediately read " Err:'

The tone control may be set Improperly. It is important that the tone control(s) be set so that the high frequencies are not attenuated. Some trial and error is involved here too.

Many cassette recorders invert the phase of the signal in the process of recording and playing back. If tapes made on your casstte recorder NEVER check properly and result in the " Err " message , inverted phase may be the problem. To set the DX to read inverted data , press the 0 button before pressing PLAY or LOAD. The display wil read

-CAS:' indicating that the DX is expecting inverted data.

TALK TO THE WORLD

The OX can be connected to most other electronic musical instruments

, as well as computers and tape recorders. The OX can operate in sync with other equipment by interconnecting timing signals, and notes can be exchanged via MIDI or trigger pulses.

The OX is designed to operate synchronously with a variety of other devices. The OX can start automatically from these devices as well as slave to its own tape sync pulse while driving other devices.

The OX sounds can be played from other sources

, such as trigger pulses and MIOI notes. Notes played on another MIDI drum machine can actually be recorded on the

OX.

Using The DX With Oberheim Sequencers and Drum Machines

The OX . DSX Polyphonic Sequencer, and DMX Orum Machine have been designed to operate in sync with each other. When the OX runs in tandem with a DSX or another drum machine , one unit must be the master and the others

, slaves.

Other Sequencers and

Drum Machines

There are a variety of ways that the OX can be connected to other equipment. Consult the INTERFACE GUIDE as well as the manual for your other equipment tor the optimum hookup for your application.

SYNCHRONIZING WITH

THE EXTERNAL CLOCK

The Exernal Clock generally provides the "

tightes" syc

between machines and is the recommended timing source if you have a choice of hookups. The DX can be set to three different clock rates: 96

, 48 , or 24

Puls per

Quarter note. Most equipment uses one of these standards. The extemal clock can be use for timing at the same time that MIDI is use for notes.

Setup

For bes results , tum off both units before conneting. Using a cable with a 1/4" phone plug at each end, connect the CLOCK OUT jack on the rear panel of the unit to be the master to the CLOCK IN jack on the rea panel of the unn to be the slave.

The DX can be interfaced wnh other Oberheim components using the tape jacks instead of the clock jacks. Try this hookup is you experience excesive noise.

Auto Start

If a slaved DX has its Auto Start function tumed on , n will recognize incoming clock pulse and automatically enter the PLAY mode whenever clock pulse start. If n does not se any pulse for 125 miliseconds (1 /8 seond), n wil automatically

STOP. These feaures allow the DX to be remotely stared and stoppe by the extemal clock pulse.

Note that pressing STOP will not stop the DX clock pulse continue; the DX wil recognize the continuing clock pulse and jump back into PLAY after the STOP buton is release. To stop the slave DX

Turning on SONG CHANGES (EDIT PARAMETER 12) enables remote selection of

Songs (not Sequences) via MIDI. The DX transmits and receives Songs 00-49.

Press RECORD and PLAYas before. The slave units will start as soon as the master

OX starts recording.

Recording as

Slave

Follow this procedure: Turn AUTO-

START OFF (Edit Parameter 02); Place the DX into

Record by pressing RECORD and PLAY; Then start the master clock source.

METRONOME AS CLOCK

SOURCE

The DX has also been designed to slave sequencers and arpeggiators

, using the metronome output. The CLICK OUT outputs the metronome at all times for this reason.

The Tempo as well as the Click Value of the Metronome wil control the rate of the metronome pulses. The Metronome output is -; 12 Volts DC

, 900 millseconds duration.

The Metronome can be set to click in a programmable rhythm instead of a steady click. See EDIT PARAMETER 04 (SET PROGRAMMABLE CLICK).

SYNCHRONIZING TO TAPE

You can record a sync tone from the OX onto tape

, and then use the sync tone on tape to control the DX. Sync to Tape is achieved by recording a sync tone from the TO

TAPE jack on the Rear Panel on to a track of a tape recorder

, and then playing it back to the FROM TAPE jack.

Recording The Sync Tone Onto Tape

When monitoring your tape recorder, you should hear a steady tone which is the

Leader Tone. Record the leader tone at a level of between - 5db and 0 db. Some experimentation wil give the best results for your particular setup. After recording 5 to

10 seconds of leader tone

. press PLAY on the DX at the point you wish the sequence to start. The leader tone will give way to a chattering sound much like the sound of the cassette data. This is the timing data. When the DX stops playing the leader tone will return.

F A

The DX will output the timing data only while in RECORD or

PLAY. In STOP or other modes , the output wil be the leader tone. Make sure the tempo that is set on the DX is the proper tempo, because the tempo wil be controlled by the sync tone when playing back. (Because the DX is reading timing information from the tape

, the DX wil tollow changes in the tape speed within a range of about 20% up or down.

Playing The Sync Tone To

Sync The OX

Connect the LINE OUT of the tape recorder to the FROM TAPE jack of the DX.

Set the TIMING SOURCE to " S" for tape Sync (EDIT PARAMETER 01), and turn

AUTO START " ON" (EDIT PARAMETER 02). Start the tape recorder. The DX recognize the sync tone , and will start when the timing data on the tape begins and will stop when the timing data ends.

If the DX does not respond to the sync tone or if It loses time

, adjust the level of the sync tone from the tape recorder. Generally louder is better.

Note that pressing STOP on the DX wil not stop it if timing data continues; the DX will recognize the continuing timing data and jump back into PLAY after the STOP button is released. To stop the DX , it is necessary to stop the tape.

IMPORTANT: TO and FROM TAPE should be disconnected when using Timing

Sources other than tape to avoid timing errors caused by noise.

Hints

A word of advice: Getting sync to tape to work properly will probably require a bit of trial and error. So don t get frustrated if it doen t work perfectly the first time. Once you get it right, mark your settings so that it will work easily next time.

Record the Sync Tone First

Because syncing the OX or any other computer device to a previously recorded track (such as piano) is diffcult

, it is best to record the DX first , and then record the other tracks while listening to the DX. Once the sync tone is recorded , the drum machine can be reprogrammed and rerecorded at any time if desired.

A good way to achieve great drum parts is to first program a drum beat with the basic feel of the piece. Record this beat and the sync tone first. Then , after the other parts have been recorded while playing along to the basic beat. the drums can be reprogrammed to work with the recorded parts. Becuse the sync tone has been recorded first. the drum machine can be recorded last or several times during the recording sessions, and maintain perfect sync.

Check the Sync Tone / There is nothing

wors than

discovering that the sync tone doesn t sync after everyhing else has already been recorded. So

, make sure that the

DX reads the sync tone properly before recording anything else.

Set the Tape Recorder to Sync / Remember to use the Sync Playback setting if you have one (sometimes called sel-sync or simul-sync) when playing back on your tape recorder. This tape recorder feature allows playback of the tape from the record head hlch keeps the timing straight when overdubbing parts. Most three head multitrack tape recorders have this setting.

Tape Dropouts / Tape dropouts can be a problem when using sync to tape, especially on multitrack cassette recording systems. Use fresh. good quality tape for best results.

Crosstalk and Signal Blee

/ The sync tone is definitely susceptible to crosstalk from adjacent tracks of a multtrack tape recorder. Depending on the recorder , blank adjacent tracks may be necessary to maintain sync. However , the use of noise reduction may eliminate the need for a blank adjacent track.

Bleedthrough of the sync tone to other tape tracks is also a problem

. but a major cause of " bleeding sync tone " is the electronics between the drum machine and the tape. On many mixing consoles, routing the sync tone through any of the mix busses frequently causes the sync tone to bleed into al/ the busses. The best way is to patch the sync tone directly in and out of the tape recorder and keep it out of the board altogether. If more gain is needed for proper recording level. use a miGrophone input or an outboard amplifier to increase the gain. Other electronics, such as mult-channel noise reduction systems may also contribute to crosstalk.

- -...... ....--- - - -..----..----

F A

Noise Reduction / Generally, sync to tape wil work bener without noise reduction.

Noise reduction won t record the sync signal better , since the level o f the sync tone doesn t change appreciably the way that music does. However

, using noise reduction may reduce crosstalk between the sync signal and adjacent tracks. This is another one of those things to experiment with!

Recording Sync instead of the DX / Many musicians working with 4 and 8 track tape recorders don

t record the drum machine on tape at all-

they record only the sync track , and then use the sync tone to slave the drum machine when overdubbing other parts and during mixdown.

TRIGGERED NOTES

I TRIGGER INPUT Programming: I

Rccess EDIT PRRRMETERS:

The OX has an external trigger jack which enables you to control any drum or any combination of drums from an external source , such as a footswitch or a GATE.from a sequencer such as the Oberheim OSX.

The External Trigger Input acts essentially the same as pressing one of the drum buttons on the front panel. When in record , triggering any of the voices externally wil cause them to be recorded subject to the same correction schemes (QUANTIZE and

SWING) that would apply to the buttons on the front paneL

The Trigger Input is designed for a switch closure, or an inverted Moog S-

Trig type trigger. To utiize an acoustic signal such as a live drum or Simmons type drum pad. it is necessary to utilize one of the trigger interface devices on the market.

Programming the Trigger

Input

The External Trigger can be set to piay any of the drum buttons. or a combination of buttons. To set which ones are triggered, select EDIT PARAMETER 06 (see EDIT

PARAMETERS), hold the desired drum button or buttons then trigger the input. The drums will piay and the DX wil " beep:' To remove the trigger setting, hold ERASE and then trigger the input.

Several drum buttons can be assigned to be triggered by the external input. Realize that only one of the three buttons on each voice can be played at a time. so that if

, for example, you attempt to assign two of the Toms to be triggered at once

, only one wiil sound.

EDIT

The OX can transmit and receive notes played via MIDI. Drum notes are the same as melodic notes. This means that a DX can be played from a keyboard , MIDI drum pads or even another DX. MIDI notes such as these can also be recorded andplayed back as well.

Note that playing notes on synthesizers from MIDI drum machines usually does not work , because drum notes have a shorter duration than most synthesizers are capable of playing.

Setting Notes to Drums

Since correlating drums with keys on a keyboard is a matter of personal taste

. the DX enables programming a MIDI note to any of the DX drum buttons. This can be done using EDIT PARAMETERS 13 & 14.

Connect the MIDI OUT from a controller such as a keyboard or another DX to the MIDI

IN of the DX. All notes must be withi" a two and one-half octave range

, starting at the transposition setting, so change the transposition setting if the notes are not within the desired range (EDIT PARAMETER 14). Hoid RECORD and press the note desired to be the bottom of the range. The MIDI note number will appear in the display.

Next . select EDIT PARAMETER 13. Playing a note into the MiDI IN while holding a drum button sets the note to that drum. Playing a note into the MIDI IN while holding

ERASE sets the note not to play any drums. Several notes can be assigned to a particular drum button but each note cannot be assigned to more than one drum. Pressing

RECORD and ERASE clears all settngs.

There is an informal standard arrangement used by other drum machines which is incorporated within the DX' s default configuration shown in the accompanying keyboard diagram. The DX can be reset to this configuration by pressing RECORD &

COpy while in EDIT PARAMETER 13.

When using the OX to transmit drum buttons to another instrument, only the highest note programmed to that drum wil be transmitted.

REALTIME MIDI RECORD

One additional feature of the DX is the ability to transfer sequences between brands

diferent

of drum machines. This is done by recording on the DX while slaved to another drum machine. The second machine sends notes across MIDI as it plays them

, and the DX simply records the notes that are received.

To transfer sequences this way:

Connect the two drum machines so that the OX is the slave unit.

Set the EDIT PARAMETERS on the DX:

same as master probably On

Set the master drum machine to transmit MIDI timing. Make sure that the Tempo

Length , and Quantize settings of the slave are appropriate for the sequence to be recorded. Press RECORD and PLAY on the slave unil, then start the master.

Remember that the DX wil record the assigned MIDI notes, which are not necessarily the same drums on both machines. Make sure that the drums of the master machine are assigned to appropriate buttons on the slave. See "

Setting Note to Drums;' above.

Some other models of drum machines can also record from the DX via MIDI. If the drum machine can read MIDI notes from the DX, it should be able to record them. For more information , refer to the INTERFACE GUIDE as well as the owner manuals of the other drum machines.

FOOTSWITCHES

On the rear panel are two jacks for footswitches. These inputs are designed to be used with switches with a MOMENTARY CLOSED configuration such as those available from Oberheim.

Start Faatswitch

When in sequence mode (all button lights off pressing the START footswitch will play the sequence from the beginning. Pressing it again wil stop it. Pressing it once more

wil restart the sequence from the beinning.

When in song mode (Song button light on) the switch works a bit differently. From

STOP , pressing the footswitch starts the song from the

beinning. Pressing it again

will stop it. If the footswitch is pressed once more , the song will continue from where it stopped.

Next Footswitch

When in sequence mode (all button lights off pressing the NEXT footswitch advances the DX to the next sequence. When playing a sequence

, the DX wil wait until the sequence currently being played is finished before starting the next sequence.

When in song mode (Song button light on) the switch works a bit differently. From

STOP , pressing the footswltch advances the DX to the next song. While playing a song, if the NEXT footswltch is held down at the end of a sequence

, the DX wil vamp;' that is

, repeat the current sequence, and not advance to the next sequence in the song. Releasing the switch will allow the song to continue.

MORE INFORMA TION

ABOUT MIDI

MIDI (Musical Instrument Digital Interface) is designed to allow computer controlled musical instruments such as the OX to communicate with each other.

Messages

There are several different types of data messges that are transmitted via MIDI:

VOICE / These are messages about notes. MIDI transmits a NOTE ON and a NOTE

NUMBER when a note is played on a keyboard or drum machine. On some devices velocity is transmitted as well. When the note is release

, a NOTE OFF is transmitted.

Levers , Wheels , Program Changes , Footswitches, and Pressure are also transmitted as Voice Messges, however these are not utilized by the ox.

COMMON / Among the Common Messages is Song Select

, used to change from one

Song to another.

REALTIME / These are commands that control sequencer timing and start/stop information , that tell a slaved sequencer or drum machine when to start and at what tempo to play.

EXCLUSIVE / Exclusive messages are used for data storage and anything else specific to a particular machine. Each manufacturer has its own System Exclusive

10.

Channels

MIDI transmits on 16 independent channels at once , which means that information for many different machines can be transmitted on the same MIDI cable. The OX can transmit on any channel, and receive on any channel. EDIT PARAMETER 07 sets the receive channel , EDIT PARAMETER 08 sets the Transmit Channel.

Omn;

Mode

The DX can be set to receive on all 16 channels at once by turning OMNI MODE on.

EDIT PARAMETER 09 turns on Omni Mode.

Timing

MIDI sends start and stop commands for running sequencers and drum machines.

Timing pulses are also transmitted at a rate of 24 pulses per quarter note. The exact rate depends upon the master Tempo setting. Set EDIT PARAMETER

01 to " d" to slave the DX to MIDI. Turn on EDIT PARAMETER 10 to transmit MIDI timing. To receive MIDI timing set EDIT PARAMETER 01 to "

Song Select

The SONG SELECT command enables remote selection of Songs (not Sequences) via MIDI. The DX responds to Songs

009.

MORE INFORMATION

ABOUT DlmTAL AUDIO

The DX is not a Synthesizer. It does not synthesize sound. What it does is play back sounds from it memory. These sounds are stored as numbers

, inside special integrated circuits called ROMs (Read Dnly Memory) which are pre-programmed. Before explaining how digital audio works , let's digress for a minute and discuss how regular analog audio works:

Sound , as far as your ears are concerned. is caused by very small but regular changes in atmospheric pressure. The air moves back and forth, over and over

, alternately pushing and pulling on your eardrums and the rest of your body. When these waves of air occur between 20 and 20 000 times per second, your brain perceives them as sound. Anything that makes noise must ultimately disturb the air in this sort of regular way. Look at the low frequency speaker in your sound system. If you turn the voiume way up (don t damage your speakers , though!) you will see the speaker (and feel the air near it) moving in and oUl, in exactly this sort of regu(ar movement.

So what any analog audio system does , is provide a pattern of regular movement

(oscilation) for the speaker to move in , so that you feel the air moving in this same pattern so that your brain can translate all this into sound and you can HEAR! Look at a

, phonograph record very ciosely and you wil see the same repeating wiggles that are amplified by your amplifier to move your spekers.

Digital audio stores, not the oscillations that move your speakers, but a series of numbers that represents those oscilations. Take the groove from that phonograph record and, in your mind , stretch it out in a straight line and piace it on a piece of graph paper.

Now if you went from the left end of the graph to the right, and everY centimeter wrote down a number that represented how far that phonograph wiggle moved up and down , you would become a recorder of digitl audio. Now

, if you took another piece of graph paper and plotted all those numbers that you just wrote down

, you would do what a digital audio recorder does to play back.

So what is programmed inside an ROM in the OX is a series of numbers (lots of numbers!) that represents the sound of a snare drum. Another one has the representation of the sound that a cymbal makes . and so on , for all of the sounds.

This Glossary contains definitions of terms as used in the OX Manual.

Address

A location in memory that contains DATA.

Beat Value

The note value of the time signature. In a time signature of 3/4 equal to a quarter note

, the BEAT VALUE is

, and there are three quarter notes per measure.

Click Value

The note value of the metronome click. The CLICK VALUE can be the same or differ-

ent than the BEAT VALUE.

Control Voltage

An electrical signal which can be used as an input to Voltage Controilable devices

such as Oscilators

, Filters , Amplifiers , etc.

Data

DATA is the information that is processed by the MICROPROCESSOR. It is stored in an ADDRESS.

Default

The result of not making decisions concerning parameters in the DX. If you do not specify how long a sequence is to be for example, the DX will DEFAULT and specify that the length is to be two bars.

Event

Any number of drums that are played on the same beat. The DX has the capacity to store 2200 EVENTS , each of which can contain between 1 and 6 notes.

Gate

An electrical signal which can be used to trigger Envelope Generators and other time dependent devices.

Master

The unit that provides timing, notes, or other data to control slave units that are connected to it. Changing the master wiU generally change aU of the siave units as well.

Microprocessor

The MICROPROCESSOR is the " brain " of the DX. It looks at the

SOFTARE instruc-

tions and then carries them out , reading DATA from the proper ADDRESSES

, performing the instructed function , and then writing the result in the proper ADDRESS.

Part

In the DX the term PART refers to a segment of a Song. Each Sequence recorded in a

Song adds another PART to the Song. There can be up to 255 PARTS contained in a

Song, each PART can be one of the one hundred sequences.

Punch Out

Punch In

Switching from Play to Record (punch in) or Record to Piay (punch out) without stopping. A recording studio term.

Quantize

A process of rounding off , in the case of the DX the rhythms that are played , to the closest specified increment. in the DX , your recordings can be QUANTIZED to the nearest Half note , Quarter note, Eighth note , or other smaller subdivisions down to a

1/192 note.

RAM

RAM or Random Access Memory acts like a piece of scratch paper for the MICRO-

PROCESSOR. Unlike Read Only Memory (ROM , PROM , or EPROM), RAM can be read from AND written into by ttie MICROPROCESSOR. RAM is usually used in a oomputer sysem to store information that is constantly changing. In the case of the

, that includes notes , tempos , sequences , etc.

ROM

This acronym stands for Read Only Memory, which is exactly what it is

, a memory chip that can only be read by the MICROPROCESSOR , and can not be written into iike the

Random Access Memories .

(RAM).

Sequence

A succession of events stored in the DX as numbers. The DX wil remember the events as played and then wil repeat them upon command.

Slave

A unit that is controlled from another source. The remote source can provide timing, notes , or other data to control slave units that are connected to it.

Software

The computer program or instructions that the computer follows to do its assigned task. In the DX and other Oberheim products, the SOFTARE is stored in ROMS located on the circuit boards.

Song

A combination of sequences.
