The equipment described ⁱⁿ this manual ^generates and uses radio-frequency energy. ^{Ifit is}not installedand used properly, thatis, instrictaccordancewith ourinstructions,

it may cause interference with ^radio andtelevision receo- tion.

Thisequipmenthas been tested and found tocomplywith the limits for a Class B computing ^{device in} accordance with the specifications in Subpart J, of Part 15, of FCC

Rules. These rules aredesigned to provide reasonable ^pro- tectionagainstsuchan interferenceina residential ^installa- tion.

However, there is no guarantee that the interference ^will not occurⁱⁿa particular installation. ^Ifthisequipmentdoes cause interference to radio or television reception, which can bedetermined by turning theequipment on and^off, the user is encouraged to try to correct the interference bythe following measure:

•Disconnect other devices and their input/output cables one at time. If the interference stops, it is caused by eitherthe other device or^itsI/Ocable.

These devices usually require Roland designated shielded I/Ocables. ForRolanddevices,youcan obtain the proper shielded cable from your ^dealer. Fornon Roland^devices, contact themanufactureror dealerfor assistance.

If your equipment does cause interference to radio or television reception,you cantrytocorrect the interference by usingone^ormoreofthefollowing measures:

•TurntheTVorradio antenna^untiltheinterference stops.

•Move the equipment to onesideortheother of theTV

orradio.

•Move the equipment father away fromtheTV orradio.

• Plug the equipment into an outlet that isona different circuit than the TVor radio. (That is, makecertainthe equipment and the radio ortelevision set areoncircuits controlled bydifferent circuitbreakersorfuses.)

•Consider installing a rooftop television antenna with coaxial cablelead-inbetweentheantennaand TV.

m ^OPERATION

1. PLAY, EDIT & WRITE

Set up the JX-8P with the necessary equipment (such asamplifier andspeaker), thenturntheJX-8P

on, and ^{itwill be readyto}beplayed (=PLAYMode).

There are 96 different tone colors preprogramnned

in the JX-8P's memory; 64 preset tone colors, another 32 inthe internal memory, (and 32 on the optional cartridge).Youcan recallanyofthosepat- ches byflick of a switch, then editit toyour taste (= EDIT Mode). This editing operation, however, does not automatically rewrite the existing tone

color.

If you wish to write the edited tone color, an ap- propriate writing operation isrequired.The 64Preset tonecolors,howeverwillneverbeerased,while the other 32 can be inevitably replaced with new pat- ches by the writing operation (= WRITE Mode).

2. PLAY MODE

Checkifalltheconnectionsare correctlymade, then turn alltheunitson. The Displaywill respond with:

While the abovedisplayisseen, theJX-8P is being tuned up, therefore cannot be played. When the tuning-up is finally completed, the number at the rightside ofthe Displaywillbecome ^"1".

Thenthe Display will be as shown below.

If this happens, push any of the Tone _Selector Buttons other than 1, and the flashing will stop, turningtheJX-8Ptothe Playmode.

A. SELECTING ATONE COLOR ^B. PERFORMANCE CONTROL ^SECTION

Any tone color can be recalled by using the Bank Selector Button © ^{and the Tone Selector Button}

©. There are four Banks in the JX-8P as follows.

P^{: 32 Presettonecolorswhich cannotbeerased} from memory

-P: 32 Preset tonecolors which cannot beerased from memory

1 ^: 32tone colors in the Internal Memory

C^: 32 tone colors in the Cartridge Memory

In each bank ofPand- preprogrammed.

there are 32tone colors

All thetone colors can be editedtoyour taste, but thePresettonecolorscannotbe erasedfornewpat- ches. Other 64tone colors in the internal memory and cartridgecan be replaced withnew patches by the writing operation.

The Memory Cartridge can be ^easily connected or disconnected, therefore, canbe effectively usedto

expand the memory of the JX-8P.

Operation to select a tone color

® Assignthe bank you want by pressing the rele-

vant Bank Selector Button _(D.

Press the Preset Button, and theBankPand-Pare

alternately selected.

® Assign the number ^{ofthe tone color} you wish to call by pressing the relevant Tone SelectorBut- ton ©.

1) Pitch Bender /LFO Lever

Movethis lever tochangethe pitch. Guitar'sbend- ing like effect can be obtained. At ^its center posi- tion, thishasnoeffecton theJX-8P's sound, while theleftand ^rightextremesofmovementachieve the same amount^ofthepitchbend effect.Themaximum

effect ofthe bender canbe optional with theBend RangeSwitch®;^{Major 2nd,} MinorSrd, Major3rd, and Perfect 5th.

Pushing this leverforward will result in vibrato ef- fect. Ifthesoundhasnovibrato,thesoundwilltake on usual vibrato effect, and if the sound already takes on vibrato, the effect will be deepened.

2) After Touch

AfterTouch isthe effect caused by^pressing down

a key hard after pressing the key in usual manner.

The JX-8P's After Touch can change any of the following 3 effects.

Vibrato The vibrato effect is deepened.

Brilliance The higher frequency is emphasized, therefore the sound becomes brighter.

Volume The volume is increased.

Operation for After Touch

3) Portamento

The^{portamentoeffectwillbeonbysettingthiePor-} tamentoSwitchtoON^.Thetimeneededfor asound to change from a pitch tothe other can be altered by using the Portamento Time Knob ®.

4) Key ModeSelect

The JX-8P contains 6 sound modules. Six dif-

ferentkeyassignmodesareprovidedtodecidehow

these6synthesizermoduleswillbe assignedtothe keys played.

I ""J POLY with the Indicator lighted

This mode turns the JX-8Pto a 6 voice polyphonicsynthesizer assigningonesyn- thesizermoduletoeachkey pressed.This

issuitable forthesound whoseenvelope curve is similar to piano's or guitar's, therefore chosen for usual performance.

I

""J POLY with the Indicator flashing

This mode is very similar to Poly mode above assigning only one synthesizer voice to each key pressed. The ^primary advantage of this mode ^isthat only the lastnoteornotes played togetherreceive natural release length. This mode ^is

suitable for the performance with por- tamento effect.

SOLO with the Indicator lighted

This mode turns the JX-8P to a single voice synthesizer thatassignsone module to each key.

jl ^{SOLO with the} Indicator flashing This mode ^{turns the JX-8P to the} monophonic synthesizer that assigns 6 modules to one key pressed.

Please be sure thatyou are nottouching any key on the keyboard while changing thekeymodes. Otherwise,JX-8Pwilllose thesound. Ifthishappens, ^releasethekey once, then press the key ^again.

I J UNISON with the Indicator lighted

In this mode, two sound modules are assigned to each key, therefore the createdsound isricherthaninPolymode.

That is, the JX-8P becomes 3 voice sy- nthesizer.

I j UNISON with the Indicator flashing Thisissimilartothe Unison mode^above,

but the one module of the two modules

is one octave lower than the other.

C. PATCH CHAIN

Theremaybesometonecolorswhicharemoreoften used. Itwillbe handyifthesepatchesare collected in sequence and called during live performance in

the same sequence. The JX-8P's Patch Chain function allowsyouto write 8 particularpatchesin

sequence and ^recall them one after another, just bypressing buttons. Eachpatchinthe Patch Chain can retain a tone color with different settings of Key Mode, ^AfterTouch, Bender Range, Portam- entoON/Off, Bend LFODepth,Unison Detune and Portamentotime.

Operation for callingthe Patch Chain

©Press either the Patch Chain Bunon | J ^or

I "J ®. ^{Then the} Display shows "1" atthe left side, and the number and name of the correspon- ding patch.

(D Press either | "J ^{or |} 'J ^toadvanceor back up a patch program ⁱⁿ the Patch Chain.

WhileusingapatchprogramofthePatch Chain,you may notice that it does not sound ^{faithful to} each position of the knobs in the Performance Control Section (such as Bend Range, Portamento). This ^is because the settings of the Performance Control Sectionarewrittenintoeachpatchprogramtogether with othersettings,andthe actual positions ofknobs have noeffecton the sound.However, ifyoumove

the knob even slightly, the value of the parameter written inmemoryistemporarily cancelled and ready tobe ^controlledmanually. Thisdoesnot rewrite the value in memory, so if you want to retain it, ap- propriatewritingoperation is required. (SeeEditing Patch Chain in" il 4WRITE MODE" on page 22.)

Patch Chain is afunction ofremembering the com- bination ofthe 8 patch programs^{with different ef-} fect and mode settings, that is, ^it has no ability of retaining the nature of the patch programs ⁱⁿ the Chain. Therefore, ^ifthe patch programs are edited and overwritten or replaced with new patches, the Patch Chain accordingly changes.

Ifyou wantto return tothe usual Play mode, turn the Power Switch Q ^{OFF once, then turn it ON}

again.

3. EDIT MODE

Likeany analog synthesizer, theJX-8P had various parameters whichcan be editedforsoundsynthesis.

The JX-8P, however, doesnot feature l<nobs or swit- ches on ^itspanelforyou totouchormove. Instead, there^are twomethods of synthesizing. Oneis call- ingeach parameterandchangingitsvalue withthe Edit Konb. The otheris using the optional progra-

mmer PG-800 which works just like pane! con- trolsofa synthesizer.
