These buttons work togethe r to create four arpegg iator modes: If the UP button is on, the notes will arpegg iate in the order played. If the DOWN button is on, the notes will arpegg iate in the reverse order in which they were played. If BOTH the UP and DOWN buttons are on, the notes will arpegg iate first in order, and then in reverse order .. If NEITHER the UP nor the DOWN buttons are on, the notes will arpegg iate in random order. The random sequenc e is weighte d. so that the first note played will sound more often than the others, and that a note will not sound twice in a row.

LOWER & UPPER

These buttons are used to assign the ARPEGGIATOR to either or both halves of the keyboard when in SPLIT or DOUBLE. In SPLIT, the arpegg iator will first arpegg iate the LOWER half of the keyboard and then the UPPER half regard less of the order in which the notes were played (except in reverse "DOWN" mode in which case the UPPER half will play first). Either the LOWER or the UPPER button (or both) can be selecte d when in Split or Double.

Sound Programming Controls

P R O G R A MM I N G

C ONT R OL S

The controls described on the next few pages are used control the sound of the 08-8. It is the settings of these controls that is actually stored in the 08-8 's program memory. Any sound recalled by the programmer can be modified (edited) by changing these Sound Programming Controls. The controls add to, or subtract from, the settings stored in the computer program. For example, the release time of the LOUDNESS ENVELOPE can be made longer than programmed simply by turning up the RELEASE control on the LOUDNESS ENVELOPE. This feature allows quick yet smooth modifications of existing programs. When selecting a program, the front panel settings do not affect the sound of the instrument. For instance, if a sound had originally been programmed with a FILTER FREQUENCY setting at 12 o'clock, but later the program is recalled with the FILTER FREQUENCY control set at 9 o'clock, the program sound will be the same as if the FILTER FREQUENCY control was set at 12 o'clock. If it is desired to further increase or decrease a control setting, and the control is already at its maximum or minimum position, simply rotate the control all the way in the opposite direction and then make your desired setting.

These switches choose the waveform of Oscillator 1. If the SAW switch is on, a sawtooth wave is selected. Sawtooth wave contains all of the harmonic overtones.

If the PULSE switch is on, a pulse wave is selected. Compared to a sawtooth wave, a pulse wave is missing some of the harmonics (the harmonic spectrum of the pulse wave is controlled by the PULSE WIDTH control), and the sound is thinner as a result. If BOTH the SAW and the PULSE switches are on, then both sawtooth and pulse waves are selected. This combination creates and extremely fat sound. The PULSE WIDTH control and the PULSE WIDTH MODULATION from the LFO will still affect the pulse wave in this mode. If NEITHER switch is on, a triangle wave is selected. The triangle wave has the harmonics of the sawtooth wave, only they are much softer in volume relative to the fundamental, and the resulting sound is closer to the pure tone of a sine wave.

Filter

The Voltage Controlled Low Pass Filter (VCF) are used to control the brightness of the sound, filtering out the higher frequencies ( the "buzz") in a very controllable manner. The Filter is arguably the most important component in a synthesizer, because it is the primary control of the timbre, or tone color of the sound. Because of this, the filter on each voice of the 08-8 can be set to two modes: 2-Pole and a 4-Pole. In the 08-8, the Filter Section also selects the sound sources (Oscillators and Noise) that are used in the patch.

RESONANCE

This control determines the amount of resonance ( "Q" or "emphasis") of the Filter. The RESONANCE emphasizes the cutoff frequency of the Fi1 ter. As the RESONANCE is incr·eased, the overall volume of the sound will increase in the 2-POLE mode and decrease in the 4-POLE mode.

MODULATION

This control determines the amount of Filter Envelope which modulates the Filter. Modulation of the Filter by the Envelope is a critical element in the synthesis of brass sounds as well as creating percussion in organ sounds, to name just a few uses. The MODULATION control also determines how much Filter Envelope will modulate OSC 2 when the F-ENV switch is on. The LFO can also modulate the Filter. See "MODULATION SECTION"

DSC l ON

When this switch is on, Oscillator l is routed into the Filter.

DSC 2 HALF /FULL

When either of these switches are on, Oscillator 2 is routed into the Filter. The FULL switch selects the full output of the oscillator and the HALF switch selects a signal level approximately 5 db below full output.

Filter Envelope

ATTACK

The Attack section of the envelope operates as soon as a key is pressed on the keyboaid. This control sets the time the Filter takes to get to its maximum effect, as determined by the MODULATION control in the FILTER SECTION. The shortest time is selected by setting the ATTACK control fully counter-clockwise.

DECAY

The Decay section of the envelope comes into operation as soon as the envelope has reached its maximum level (as soon as the Attack is completed). This control sets the time the Filter takes to reach the sustain level, as set by the SUSTAIN control, while a key on the keyboard is being held down.

SUSTAIN

This control sets the level the Filter Envelope goes to following its initial decay, as set by the DECAY control. The Envelope will stay at the Sustain ~evel as long as the key on the keyboard is held down.

RELEASE

Once the key is released, the Envelope moves to the Release section, and completes its cycle. The RELEASE control sets the time the Filter takes to go from the Sustain level, to the off level. If the SUSTAIN control is set to minimum, the Release section will have no effect on the sound if the key is pressed and held down. If the key is pressed and immediately let go (in less time than the combined Attack and Decay time), then the Release Section will still have an effect.

The Release of Envelope can be cut short by pressing the WRITE button.

When the F-ENV switch is on, the Filter Envelope modulates OSC 2 as well as the FILTER. The pitch of OSC 2 will directly correspond to the shape of this Envelope. The ATTACK determines how fast OSC 2's pitch will rjse, the DECAY determines how fast DSC 2 will decrease in pitch to the level set by the SUSTAIN control, and. the RELEASE determines how fast OSC 2 will decrease in pitch after a note has been released. The MODULATION control in the Filter Section will control the range of the effect of the Filter Envelope on both the Filter as well as Oscillator 2.

PORTAMENTO

This contro l determ ines the rate of portam ento or "glide " of each voice as that voice' s pitch is change d. Note that the portam ento of the 08-8 is polyph onic, so each voice will glide from note to note indepe ndentl y of all other notes. Portam ento als6 functi ons in UNISON mode. There are severa l Portam ento Modes. For more inform ation, see "PORTAMENTO MODES".

UNISON

When switch ed on, causes all voices to be sounded by one key depres sion. In UNISON, the 08-8 keyboard operat es with low note rule, which means that the lowest note played on the keyboard will always have priori ty. When in SPLIT, the UNISON mode is indepe ndent for the two halves of the keyboa rd, so if the uppe~ half is in UNISON, then only the lowest note of the upper half of the keyboard will affect it.

OSC 2 DETUNE

This contro l allows Oscill ator 2 to be tuned either flat or sharp relati ve to Oscill ator 1. Turnin g the contro l to the left makes Oscill ator 2 go flat and to the right makes it go sharp. The LED above the OSC 2 DETUNE contro l turns on when the Oscill ator 2 is detune d from Oscill ator 1.

THE LOW FREQUENCY OSCILLATORS (LFOS) are used for modulation at low frequencies --that is, frequencies near or below the range of hearing. If you were to listen to an LFO directly, you would not hear anything; however by controlling the frequency or pulse width of an oscillator or filter, the effect of an LFO becomes apparent. The 08-8 contains three LFOs: two are controlled from the Modulation Section on the front panel and are discussed here; the third is controlled from the Modulation Panel to the left of the keyboard ( see "PERFORMACE CONTROLS II) •

QUANTIZE

This switch quantizes the sliding portamento into semitone steps.

LFGA TO

THIS MODE CAN BE TURNED ON ONLY WHILE IN UNISON MODE. When legato portamento is on, notes will slide only when played legato, e.g. without releasing the key while going from one note to another. When notes are played detached, no portamento will occur. This feature enables portamento to be used expressively while soloing. Legato Portamento can be used in conjunction with any of the other portamento modes, but only in unison. Turning off UNISON will automatically turn this mode off.

EQUAL TIME

This switch makes the glide time between notes independent of the interval between the notes, e.g. it will take the same time to glide from CO to C£0 as it would from CO to C6. The range of the glide time is smaller· than with the regular portamento mode. Note that BEND PORTAMENTO and EQUAL TIME PORTAMENTO cannot be on at the same time.

EXPONENTIAL

This mode is essentially identical to the equal time portamento but the "shape" of the glide is exponential instead of linear. This means that the pitch will glide slower and slower as it gets closer to the destination note. This kind of portamento was used on the Oberheim Modular 2,4 & 8 voice synthesizers. Note that EXPONENTIAL PORTAMENTO cannot be on at the same time as either EQUAL TIME or BEND PORTAMENTO.

Prograrnm ing Portamento Bend

Press and hold the PORTAMENTO BEND control, and play a note on the keyboard. The C two octaves from the bottom of the keyboard (CZ) equals zero bend, and each key away from CZ (up or down) equals a quarter-tone, e.g. pressing D3 will set notes to gliss from a perfect fifth above.

Held Chords being transposed will not portamento if the PORTAMENTO BEND is on. Notes being Arpeggiated operate in the opposite manner: they will portamento only if the PORTAMENTO BEND is on. So, when using portamento with Held Chords that are being transposed and Arpeggiated, you have a choice: With the PORTAMENTO BEND on, each arpeggiated note will portamento; with the PORTAMENTO BEND off, only the chord transpositions will portamento.

CASSETTE

I NT E RF AC E

The 08-8 is equipped with a Cassette Interface which enables programs contained in the program memory to be stored externally on an audio cassette. All that is require_d to use the Cassette Interface feature is an audio cassette recorder with reasonable frequency response and a pair of mini-plug to mini-plug audio connecting cables. NOTE:

The cassette player must have an earphone or ext. speaker output (a ~INE OUT will not work).

NOTE:

The 08-8 Cassette Interface is not compatible with other Oberheim synthesizers.

8.1.

Tape Recorder Hookup Connect the Earphone or Speaker output of your cassette recorder (a Line output will not work) to the jack labeled "TO OUTPUT" on the rear of the 08-8. Connect the "TO LINE INPUT" jack on the rear panel of the 08-8 to the Line or Aux input of your cassette recorder. If the recorder does not have one, connect the "TO MIC INPUT" jack on the rear panel to the Mic input of your cassette recorder.

NOTE:

8.2.

To reduce hum, the "TO LINE INPUT" and "TO MIC INPUT" jacks have no ground connection. For this reason, it is necessary to connect both the Input and the Output cables when recording data onto the cassette recorder. Cassette Interface Controls

Press the RECORD switch on the tape recorder. You should now hear a steady tone through the main outputs of the 08-8. The MASTER VOLUME control will adjust the volume of the tone heard in the OB-S's outputs, but will not affect the level of the Cassette Interface Output.

3)

Press the RECORD switch on the 08-8. After the RECORD switch is pressed, ten seconds of the steady "leader" tone will be sent out followed by sixteen seconds of the actual memory information . During these twenty-six seconds, the light on the RECORD switch will be on. The GROUP lights (A, 8, C, D) come on in sequential order ("A", "8", "AB", "C", "AC", etc.) indicating that information transfer is taking place.

The RECORD function can be cancelled by pressing the HOLD button. 8.4.

Playing Programs From Tape Into The 08-8 1)


2)

Press PLAY on the tape recorder. You will be able to monitor the tape through the main outputs of the 08-8. The MASTER VOLUME will control the volume for monitoring the tape.

3)

As soon as the "leader" tone is heard, press the PLAY switch on the 08-8. At least three seconds of the "leader" tone must come between pressing PLAY and the rough sound of the memory information . The light on the PLAY switch will be lit from the time the switch is pressed until the first of the memory information is recognized. At that point, the GROUP lights (A, 8, C, D) come on in sequential order ("A", "8", "AB", "C", "AC", "ABC", etc.) indicating which group is being transferred . The Splits and Doubles are transferred last. ·If the t-EMORY PROTECT switch on the Rear Panel of the 08-8 is set to PROTECT, the PLAY light will not operate.

4)

If an error is detected, the PLAY light will flash.

The PLAY function can be cancelled by pressing the HOLD button. NOTE: If a cassette of patches from an 08-8 with A7 or previous software is loaded into an 08-8 with AS software, it is possible that some of the new features of the AS software (portamento and LFO invert functions) will be turned on in some of the programs. To eliminate them, simply edit them out of each patch and re-write it into memory. For more information , see the SOFTWARE REVISIONS section of this manual.

Cassette Interface

Checking Tapes

The CHECK function of the Cassette Interface enables verification of the data on a tape without actually transferring the data into the OB-B's memory. A TAPE SHOULD ALWAYS BE CHECKED AFTER RECORDING. 1)


2)

Press PLAY on the tape recorder. You will be able to monitor the tape through the main outputs of the 08-8.

3)

As soon as the "leader" tone is heard, press the CHECK switch on the 08-8. As with the PLAY switch, at least three seconds of "leader" tone must follow pressing the switch and precede the rough sound of the memory information. The CHECK light will be on during the reception of the leader tone and the GROUP lights will sequence, just as during the PLAY operation, however no actual information transfer into memory takes place.

4)

A CHECK error is indicated if the CHECK light flashes at the end of the operation.

The CHECK function can be cancelled by pressing the HOLD button. 8.6.

Possible Causes of Tape Transfer Errors A)

There is a dropout on the tape.

B)

The playback volume is too high or too low. Some trial and error may be required. Generally the best level is as high as possible before distorion occurs (approximately 3/4 of the way up). If the playback volume is too low, the 08-8 will not acknowledge the data at all.

C)

The tone control may be set improperly. It is important that the tone control(s) be set so that neither the high nor the low frequencies are attenuated.

D)

The Batteries in the cassette machine are too weak.

The Cassette Interface is designed to work with portable cassette recorders having an "Earphone", "Speaker", or "Monitor" output. The Interface is not designed to work with tape recorders having only a line output. Our experience is that monophonic recorders work more reliably that stereo units. One cassette recorder that we have found to work well with the Cgssette interface on all of Oberheim's products is the Superscope C-ZOOLP.

The 08-8 has a number of calibrat ions that are stored in its computer memory. Mast of these are envelope time calibrat ions that are set at the factory so that the envelope generato rs in the 08-8 will be matched from voice to voice and between the upper and lower voices. These calibrat ions are ~ique to each 08-8 and are stored on tape automat ically each time you save your program s. This feature is on all 08-Bs having software version A6 or above. Under normal operatio n of the 08-8, these calibrat ions should never be altered, but the followin g provisio ns for setting them can be very useful if the unusual situatio n arises in which the 08-8 is not function ing properly .

Softw are Calib ration s

Tape Stora ge of Calib ration s The calib ration s of your partic ular 08-8 stored in compu ter memory are record ed a, tape autom atical ly each time you save your progra ms. If for some reason your 08-8 gets out of calib ration (due to memor y drop) , the calib ration s on tape can be loaded back into the 08-8 in much the same manner as patch programs are loaded into the 08-8 from tape: l)

Enabl e the Casse tte Interf ace with the switc h on the rear panel .

2)

Press PLAY on the tape recor der. You will be able to monit the tape throug h the main outpu ts of the 08-8. The MASTER or VOLUME will contr ol the volume for monit oring the tape.

3)

Hold down all six butto ns in the FILTER sectio n (DSC l ON, OSC 2 HALF, DSC 2 FULL, NOISE, 4 POLE, and TRACK).

4)

As soon as the "lead er" tone is heard , press the PLAY switc on the 08-8. At least three secon ds of the "lead er" tone h must come between press ing PLAY and the rough sound of the memory inform ation. The light an the PLAY switc h will be from the time the switch is presse d until the first of thelit memory inform ation is recog nized . At that point , the GROUP light s (A, 8, C, D) come an in seque ntial order . If the MEMORY PROTECT switc h on the Rear Panel of the 08-8 is set to PROTECT, the PLAY light will not opera te.

4)

If an error is detec ted, the PLAY light will flash .

The PLAY funct ion can be cance lled by press ing the HOLD butto n. The calib ration s shoul d only be loaded in if the 08-8 has lost its progra ms, or the envelo pe gener ators do not seem to be opera prope rly. It is impor tant that these calib ration s are loadedting in only from a tape made from the same 08-8, otherw ise the wrong calib ration s will be loaded in. Checking a data tape will also check the calib ration s on that tape (See CASSETTE INTERFACE).

Software Calibrations

11.2. Master Reset ~~-If for somereason (memory drop, for example), the 08-8 seems to be functioning improperly (i.e. four voices out of tune with the other four, envelope generators are unmatched, transpose won't work), it is possible to reset the computer inside the 08-8. To reset the OB-B's computer, press all 8 PROGRAM buttons and the SPLIT button at the same time (use your elbow), WHILE MEMORY PROTECT IS OFF. The reason this a difficult procedure is so that it cannot be done accidentally, since all the envelope calibrations will be reset to zero. When this reset is done, the envelopes should be matched closely enough for normal operation, but to match them more accurately, the calibrations must be loaded in from tape. NOTE: These functions have been provided as a last resort when there seems to be no other way to correct a problem of envelope matching or transpositions not functioning. Since the consequences of these operations are not user repairable, contact your authorized service center or Oberheim Customer Service to determine whether or not these actions should be taken to solve a particular problem. 11.3. Reset of All Performance Controls ~~If this samer:eset procedure is done with ONLY WITH MEMORY PROTECT ON, all of the 08-8 functions EXCEPT the envelope calibrations will be reset. This can be useful when it is desired to reset the arpeggiator transpositions, bend amount, bend direction, split transpositions, etc. without affecting any of the calibrations.

NEW PAGE 2 FEATURES The latest version of the Oberheim 08-8 has eight exciting new features not listed in the current Owner's Manual. All of these features are retrofitable to any previously manufactured 08-8 at your local Oberheim Service Center. The new computer software is labeled AB. For a quick check to see which software is in your 08-8, enter PAGE 2 by pressing the CHORD/PAGE 2 button twice, and hold it down on the second push. While holding, press the SYNC button. While holding both of these buttons down, the software version will be displayed in the Programmer Section. If you currently have version AS software, the GROUP A and the PROGRAM 8 lights will light up. NOTE: If a cassette of patches from an 08-8 with old software is loaded into an 08-8 with AB software, it is possible that some of the new features will be turned on in some of the programs. To eliminate them, simply edit them out of each patch and re-write it into memory. The software version AB contains the following new features: 1)-2)-3)-4)-5)-6)-7)-8)--

LEGATO PORTAMENTO EQUAL TIME LINEAR PORTAMENTO EXPONENTIAL PORTAMENTO INVERT LFO FREQUENCY MODULATION ON VCO l INVERT LFO PULSE WIDTH MODULATION ON VCO 1 VCF TRACKING OF THE BEND LEVER REVERSABLE BEND LEVER RfVERSABLE MODULATION LEVER

1)

LEGATO PORTAMENTO

This mode is turned on from PAGE 2 with the DSC 1 FULL switch and is stored in the patch. THIS MODE CAN BE TURNED ON ONLY WHILE IN UNISON MODE. Turning off UNISON will automatically turn this mode off. When legato portamento is on, the portamento (any kind) will be active only when the keyboard .is played legato, e.g. without releasing the key while going from one note to another. 2)

EQUAL TIME LINEAR PORTAMENTO

This mode is turned on from PAGE 2 with the OSC 2 HALF switch and is stored in the patch. BEND PORTAMENTO (the UNISON button on PAGE 2) AND EQUAL TIME PORTAMENTO CANNOT BE ON AT THE SAME TIML When this mode is active, the glide time between any note is independant of the interval between the notes, e.g. it will take the same time to glide from CO ~o Cl 1

I

as it would from CO to C6. The glide time is controlled by the portamento rate knob. The range of the glide time is smaller than with the regular portamento mode. 3) EXPONENTIAL PORTAMENTO This mode is turned on from PAGE 2 with the OSC 2 FULL switch and is stored in the patch. BEND PORTAMENTO AND EXPONENTIAL PORTAMENTO CANNOT BE ON AT THE SAME TIME. EQUAL TIME LINEAR PORTAMENTO AND EXPONENTIAL PORTAMENTO CANNOT BE ON AT THE SAME TIME. This mode is essentially identical to the equal time portamento but the "shape 11 of the glide is exponential insteaa of linear. This means that the pitch will glide slower and slower as it gets closer to the destination note. This kind of portamento was used on the Oberheim Modular 2,4 & 8 voice synthesizers. 4)

INVERT LFO FREQUENCY MODULATION ON VCO l

This mode is turned on from PAGE 2 with the SYNC switch and is stored in the patch. With this mode on, the LFO modulation of VCO l's frequency is out of phase by 180 . degrees (phase opposition) with respect to the LFO frequency modulation on VCO 2 ar,d the VCF. 5)

INVERT LFO PULSE WIDTH MODULATION ON VCO 1

This mode is turned on from PAGE 2 with the F-ENV switch and is stored in the patch. With this mode on, the LFO _modulation of VCO l's pulse width is out of phase by 180 degrees (phase opposition) with respect to the LFO pulse width modulation on VCO 2 and the VOLUME MOD. 6)

VCF TRACKED BY THE PITCH BEND LEVER

When VCF TRACK is on, the pitch bend lev 7r controls the VCF frequency. In SPLIT or DOUBLE the VCF will only track the bend lever if it is assigned to it with the UPPER and LOWER buttons in the bend box. 7)

REVERSABLE PITCH BENO LEVER

It is now possible to reverse the direction of the pitch bend lever. To do so, hold down the UPPER and AMOUNT buttons above and below the pitch bend lever while you turn the power on. To return the pitch bend to normal operation, repeat the procedure. This setting is not stored with the pate~ but will remain in its current mode even when the power 1s turned off. When it leaves the factory the 08-8 is set for the regular direction (the right one!). 2

I

I I I I I

REVERSABLE MODULATION LEVER Same as for the pitch lever but you must use LOWER and DSC 2 ONLY ( above and below the modulation lever) while you turn on the power. As with any piece of equipment, the more you know about it, the better you will be able to use it. So experiment! You won't discover all of the capabilities of your new PAGE 2 controllers unless you do.

There are also a few features of the 08-8 that have existed in earlier software versions, but have not been explained in the owner's manual. The following features are on all 08-8s having software version A6 or above. Under normal operation of the 08-8, these features would never be used, but they can be very useful if the unusual situation arises in which the 08-8 is not functioning properly. l)

TAPE STORAGE OF CALIBRATIONS

The 08-8 has a number of calibrations that are stored in its computer memory. Most of these are envelope time calibrations that are set at the factory so that the envelope generators in the OB-8 will be matched from voice to voice ~nd between the upper and lower voices. These calibrations ·are unique to each OB-8 and are stored on tape automatically each time you save your programs. If for some reason your 08-8 gets out of calibration (due to memory drop), the dalibrations on tape can be loaded back into the 08-8 by holding down all six buttons in the FILTER section (DSC l ON, DSC 2 HALF, DSC 2 FULL, NOISE, 4 POLE, and TRACK), then pressing PLAY and then playing in the tape (MEMORY PROTECT must be off in order to play in a cassette). The calibrations should only be loaded in if the 08-8 has lost its programs, or the envelope generators do not seem to be operating properly. It is important that these calibrations are loaded in only from a tape made from the same 08-8, otherwise the wrong calibrations will be loaded in. 2) MASTER RESET

If for some reason (memory drop, for example), the 08-8 seems to be functioning improperly (i.e. four voices out of tune with the other four, envelope generators are unmatched, transpose won't work), it is possible to reset the computer inside the 08-8 by pressing all 8 PROGRAM buttons and the 3

I

I I I I I

SPLIT button at the same time (use your elbow), WHILE MEMORY PROTECT IS OFF. The reason we made this a difficult procedure is so that it cannot be done accidentally, since all the envelope calibrations will be reset to zero. To then reload the envelope calibrations, follow the procedure listed above. When this reset is done, the envelopes should be matched closely enough for normal operation, but to match them more accurately, the calibrations must be loaded in from tape. If the reset is done with memory protect on, all of the 08-8 functions EXCEPT the envelope calibrations will be reset. This can be useful when it is desired to reset the arpeggiator transpositions, bend amount, bend direction, split transpositions, etc. without affecting any of the calibrations. NOTE: These functions have been provided as a last resort when there seems to be no other way to correct a problem of envelope matching or transpositions not functioning. Since the consequences of these operations are not user repairable, contact your authorized service center or Oberheim Customer Service to determine whether or not these actions should be taken to solve a particular problem.

USING THE 08-8 MIDI INTERFACE HIDI MIDI

is an acronym for "'-isical Instrument Digital Interface. It a serial computer interface which enables synthesizers and CC"llputers to communicate. MIDI was designed to be a universal computer interface through which synthesizers and computers could communicate regardless of manufacturer. Any synthesizer or computer having a HID! interface will connect to an 06-8. is

MIDI CONNECTORS MIDI CONNECTORS are located on the rear panel of the 08-8 or, on the left end bell of an 08-8 with a MIDI retrofit. The MIDI IN connector receives MIDI information. The MIDI OUT connector transmits MIDI information from the synthesizer. Keyboard information, patch changes, and bend lever/modulation lever changes generated on an 08-8 will be sent to the HID! OUi connector. The HIDI THRU connector is used to pass MIDI information which was generated by another synthesizer/ ccmµ•Jter. Information played on an OB-8 is not available at it's own HID! THRU connector. BASIC CONNECTION The simplest application is to cor.nect 2 OB-B's together. Th~ Master OB-8 will be referred to as Synthesizer A and will, for the following demonstrations, be the cont.oller. The second GB-8 will be referred to as Synthesizer B or the Slave, e.nd 1,,1::.J.l be controlled by the Master 08-8. We will use this configuration to explain HIDI operation and associated controls. NOTE: WHEN CONNECTING COMPUTER BASED PRODUCTS TOGETHER, HAKE SUR~ POWER IS Off ON BOTH UNITS. Using-a cable with 5 pin male DIN connectors on each eno, cunneci. MIDI OUT on the master 08-8 to MIDI IN on the Slave 08-8. Turn power on and press auto tune. Notes played o~ the Mester OB-8 will also be played by the Slave 08-8.

control the other. Connect MIDI OUT on the Slave to MIDI IN on the Master. Now either OB-8 can be the Master or the Slave. Information received at the MIDI IN connectors is NOT available at the MIDI ClJT connector of the same synthesizer. This prevents an endless loop situation from occurring which would be the MIDI version of acoustical feedback.

Using the OB-8 MIDI Interface

USING MIDI WITH THE DSX The sequencing power of the DSX can be used with ANY synthesizer having a MIDI interface. With a DSX sequencer playing the Master OB-8, any synthesizer connected to the MIDI OUT connector of the Also, you Master OB-8 will DOUBLE the notes played by the 08-B. can use the {]3-8 to merely pass the DSX information to the MIDI be OUT connector causing any synthesizer with MIDI IN to controlled by the DSX.
