BATTER Y CHEC K In function mode, thi s button cause s th e display to show the voltage leve l o f the battery which preserve s th e DX7 interna l voice and programming memories when power i s turned off.
Keyboar d This i s a 61-ke y keyboard which has initial (veloc - ity) and after (pressure ) sensitivity, although these parameters must b e programmed into the voic e in order to b e useable . The keyboard ha s 16-not e poly - phonic capability or ca n b e switched to monophonic mode.
SETU P NOTE: Do not turn power On until all other connections have been made. Audi o Outpu t The DX7 ha s a built in headphone amplifier, s o stere o headphones may b e plugged into th e front panel jack. However , the instrument doe s not have a built in powe r amplifier, and thus requires an exter - nal amplifier/speaker system .
Additional Technical Installation Notes When connecting the DX7 t o an amplifier o r mixer, a maximum unbalanced cabl e length o f 2 0 feet will reduce susceptibility t o hum, noise , and high frequen.

a RAM cartridge before submitting the instru- ment for a new battery or repair. See page 49 for Cartridge Save and Load descriptions and directions. Please do not try to change the battery yourself ; expensive damage that is not covered by your Warranty may result.
5 . Play th e keyboard and then move the MODULATION WHEEL toward "MAX" . Notice it doe s not change the sound; that's becaus e you just turned OF F the Wheel' s effect.
HO W TH E DX 7 CREATE S SOUND S Breath Controller or Foo t Controller) to tur n note s u p and down withi n the existing envelopes , provided you are als o playing the notes on the keyboard. The more EG bias , the les s amplitude i s present when you play a note; the leve l increase s when you add EG bia s by advancing th e Wheel.
Algorithm s Different arrangements o f operator s are known a s "algorithms. " An algorithm i s something like a "patch " on a modular synthesizer ; i t define s the way the opera .
The results o f using different frequency ratios , a s wel l a s different algorithms, are shown graphically in the accompanying illustration. In the left column, you se e th e resulting waveforms create d by 1:1,2:1 and 3: 1 frequency ratios when a modulator i s stacke d atop a carrier — for example, operators 1 and 2 in Algorithm 5 o r 16 .
Envelope s an d Envelop e Generator s Conside r what happens when you play a note . The volume goe s u p to som e value, then eventually falls t o nothing, with som e sor t o f reasonabl y well defined pat - tern that i s characteristic o f th e particular instrument.
PROGRAMMIN G VOICES : A TUTORIA L ence whether th e envelop e had reache d LEVEL 3 and wa s sustaining, had just reache d LEVEL 2 , o r had not yet reache d LEVEL 1 . Whatever the leve l when you releas e the key , the sound immediately move s towar d LEVEL 4 a t RATE 4.
2. Assuming you want to initialize the voic e edit mem- ory (buffer), answer affirmative by pressin g [YES] . (If you changed your mind and don't want to initialize a voice, pres s [NO] ; the display won't change, but the voice will not b e initialized and you ca n selec t any other functio n you wish.
The "current" operator i s that one whose parameters are being displayed, and which i s ready t o b e repro - grammed. You ca n se e which one i s current (OP 1 through OP6 ) by looking at t.
3 0 With al l level s at the maximum o f 9 9 (excep t Leve l 4, which i s a t 0 ) and with Rat e 1 a t 25 instea d o f the 9 9 t o which the other rate s ar e set , the note builds u p slowl y when you pres s a key and turns off the instant you releas e the key If you coul d se e the envelope , i t would loo k something like this: 2 .
RATE] a s require d s o yo u ca n us e [DAT A ENTRY ] to adjus t Rat e 3 to a valu e o f 50 . When you play a note, observ e how the sound builds to a maximum, then falls to the sustain leve l a t a moderate rate and stay s there unti l you releas e the key, after which th e sound slowl y fades.
Instea d of takin g th e tim e t o reprogra m th e envelope , we as k yo u t o agai n us e th e Voic e Initializ e feature.. . i t save s time . 1 . T o gai n acces s t o th e "Voic e Initialize " function , pres s [FUNCTION] , an d the n [VOIC E INIT] , an d answe r th e displaye d prompts .
6 . Slide [DATA ENTRY] all the way down s o the fre- quency return s to 1.00 , and then pres s [OSCILLA- TOR-FREQUENCY COARSE] and us e DAT A ENTRY [+1 ] to se t th e frequency ratio to 2.00 . Then slowly move this slider up and down fully, or use these buttons while continuing to play a note 7 .
ALGORITHM # I These bracketed numbers show you where the on/off switching is done in the algo- rithm. Operators can be dis- abled (turned Off) using the [OPERATOR ON/OFF] buttons, but they remain Off only while programming. Stored voices have all operators On.
Press this button (Don't confuse it with [EG LEVEL], button 22) And repeatedly play notes until the display shows maxi- mum output level I f you are familia r with analog synthesizers, you may se e a parallel betwee n this sound and tha t o f a saw - tooth wave which i s going through a filter that has a lot o f resonance.
And again adjust [DAT A ENTRY] to hear the results of different frequency ratios as you play Leave Operator 2 set to a frequency ratio of 2.00 The sound you now hear will be simitar to that of a square wave in a conventional synthe- sizer.
9 . T o compare what the sound i s like with and without th e carrier, you don't have to tur n down the output leve l o f operator 1 ; you ca n simply tur n it off. Pres s [OPERATOR ON/OF F 1 ] t o tur n off the carrier, and tr y to play few notes .
preset voices, you can do so without "losing" this voice. There are two approaches to this. (A ) You ca n stor e this voic e in it s current stat e o n a RAM cartridge by following the instructions o n pag e 49 , or.
When you later tr y switching algorithms after adding FEEDBACK and activating the other 4 operators , you'll hear much more variation. 2 . Pul l down th e [DAT A ENTRY] slider and/or us e the [-1 ] button unti l you've selecte d algorithm 1 again.
In this cas e scalin g operato r 2 i s not necessar y s o you can omit the proces s o f setting its break point (which would b e done by pressin g [OPERATOR SELECT ] and adjusting the value a s desired) . Now play som e scale s and notice that the sound i s still reasonabl y uniform acros s the keyboard .
41 LFO SECTION BLOCK DIAGRAM ments. One MODULATION SENSITIVITY control i s provided for PITCH, and another for AMPLITUDE. I n order for you to hear the result o f any LFO PMD or AMD settings, the corresponding [MOD SENSITIVITY- PITCH] or [MOD SENSITIVITY-AMPLITUDE] param - ete r must be greater tha n zero .
3 . Pres s [PMD] (Pitch Modulation Depth), and adjust [DAT A ENTRY] for a value o f 50 , again, just to begin. Now play a few notes . You probably won't hear any change from when you started.
The display should look like this. Play several brief notes 10 . Now use [DAT A ENTRY] t o tur n the syn c OFF Again, play the same brief note severa l times, and listen to the pitch eac h time. You'll hear the initia l pitch o f each note change slightly a s the randomly timed note s interact with th e regularly oscillating LFO .
Programming th e remainin g 4 operator * S o far we have use d just 2 o f the 6 available operator s withi n the algorithm to creat e the voic e you are hearing.
In this case , we do not want thes e two segment s o f th e voice (OP1-OP 2 and OP3-OP6 ) t o combine; we want a "split" keyboard instead. (With another voice , you might want th e two voice segments to play to - gether, complementing one another.
46 press and hold down the [CHARACTER] button, then pres s individual buttons which correspon d to the letters, numbers, o r punctuation you wis h to use . You ca n determine which buttons produce which alphanumeric character s by looking a t the smal l dark brown "reversed " typ e in the right come r o f eac h button.
Any o f the prese t voice s can b e edite d to change them slightly, or totally I n fact, the term "primary voice " might be better tha n "prese t voice, " sinc e thes e voice s are not permanent like the preset s o f mos t other synthesizers .
Analyzin g an d keepin g a recor d o f voice s You ca n us e the EDIT mode to examine all the param- eter s o f eac h preset.. . or o f any voice . You don't have t o change anything, but the envelope or frequency ratio s or touch sensitivit y o f a voic e may b e useful to you in creating a new voice .
TH E INTERNA L AND CARTRIDG E MEMORIE S We have already describe d how t o play voice s that are store d in th e internal memories o r cartridge memories .
play a liv e performance and you want memorie s 1-3 2 to contain the voice s you plan to play in numerical order . This ca n b e done either in the internal memory or in the RAM cartridg e memory It s bes t t o have a t leas t 1 "blank" or unwanted voic e which you ca n eras e when doing this .

MAINTENANC E AND TROUBLESHOOTIN G Cleanin g Th e DX7 should b e cleane d with a soft, moistened cloth. To remove more stubborn dirt, us e a mild deter- gent solution on the cloth. D o not allow flui d to ru n into the instrument, and do not us e specia l cleaner s since solvent s can mar the finish.
DX SYNTHESIZE R GLOSSAR Y ADSR This is an acronym for "Attack-Decay-Sustain-Release" which, in turn, refers to the four controls provided on a con- ventional synthesizer's envelope generators. While the DX synlhesizers can simulate ADSR-type EGs , the DX EG s are more complex.
Fingere d Port a This i s an abbreviation for "fingere d portamento." This i s a functional mode o f the DX7 which i s available only when the keyboar d i s se t t o MONO operation.
Loa d I n th e DX7, "Load " describe s the proces s o f trans- ferrin g th e 3 2 voice s from one bank o f a ROM cartridge, or from a RAM cartridge, into th e 3 2 internal memories .
Sav e In the DX7, "Save " describe s the proces s o f simul- taneously placing al l 3 2 internal memory voice s into the correspondingly numbered RAM cartridg e memories . Sawtoot h wav e A waveform that contains the funda- mental and both od d and even harmonics.
