ThePhonesjack
If you prefer to play with headphones for high quality personal monitoring, plug a
standard stereo headphone set into the rear panel PHONES jack. The internal
speakers are automatically disconnected.
Use the VOLUME slider to adjust the headphone volume.
TheDamperjack
An optional footswitch can be plugged into the DAMPER jack for sustain control.
The footswitch operates like the damper pedal of an acoustic piano. Press for sus-
tain, release for normal sound.
TheAux.Outjack
Connect the rear-panel AUX. OUT jack to amplified speakers, amplifiers or domes-
tic hi-fi units for external amplification. Use audio cables with standard 1/4" jacks
and plug into the LINE IN or AUX. IN of the external amp. system. To use the
external amp. system only and exclude the internal speakers of the GK330, plug a
jack into the PHONES jack.

ment is in NORMAL mode. Every time you turn on your instrument, it sets to NOR-
MAL mode.
To return the instrument to NORMAL mode, press the [MODE] button to the left of
the display.

The GK330 has 147 PCM voices including 7 percussion kits that you can select and
play on the keyboard.
After turning on, the GK330 sets to NORMAL/VOICE mode with the display showing
a black arrow pointing to the NORMAL mode in the top left hand corner of the display
and the VOICE 1 message at the center.
In VOICE mode, you can select and play voices.

<------------ PERCUSSIVE SOUNDS ------------->
SelectaVoicewiththe numeric keypad
Using the numeric keypad is the quickest way to go directly to the Voice you need,
but you must know the exact number of the voice. The name and corresponding
number of all the Voices in memory are silkscreened above the display on the right.
You’ll see that they start from number 01 through to number 147.
Two-digit voice numbers are selected by entering the two digits in sequence.
For example, to select Voice number 17 (Organ 1), press button [1] then button [7].
Three digit voice numbers are entered by first pressing the [VOICE]/[+100] button
to specify the “hundreds”, then pressing the remaining two digits in sequence.
Dualvoice(playtwolayeredvoices)
To play with the DUAL option (with two layered sounds), press the [DUAL] button.
The message “VOICE 2” appears in the display as well as the voice number as-
signed to the layered section.
If you play on the keyboard, you will hear two sounds for every note played. In our
example, you will hear the Piano voice (01) together with Strings (49).
In DUAL mode, whatever voice selection you make will always be assigned to the
second voice.
To return to NORMAL single voice play, press the [DUAL] button again.
Keyboardpercussion
To play percussive instruments on the keyboard, select one of the 7 available Drum
Kits from the DRUMKIT group. The DrumKits are recalled using exactly the same
method used to recall a Voice; by inserting the corresponding number on the nu-
meric keypad when the instrument is in NORMAL mode (not DUAL or SPLIT).
For example, to recall the STANDARD Drum Kit, simply input voice number 141.
1. Press the [VOICE]/[+100] button to select the “hundreds”.
2. Insert the two remaining digits; “4” then “1”.
With a DRUMKIT selected, the keyboard transform into a device which plays all the
percussive sounds of a real drum kit. You can see what kind of percussive instru-
ment each note plays by referring to the silkscreened markings on the rail under the
keyboard.
To return to normal playing, simply recall a Voice from any group except the Drum
Kit group.
Note: To play all the sounds of a Drum Kit, it is important to remember that the
keyboard must not be in Split or Dual mode. Be sure, therefore, that the left
display arrow is pointing to the NORMAL function.

ThePerformances
So far, you have learnt how to select single and combined Voices in Normal, Dual
and Split modes using several panel interventions. If, every time you want to create
a preferred sound combination, you have to take several steps to arrive at your goal,
you would ask yourself if there wasn’t a quicker way of selecting what you want. The
answer lies in the PERFORMANCES which offer a quick and simple method of
recalling a panel situation at the touch of a single button.
APERFORMANCE is simply acombinationofvoices andotherpanelsettings (Voices,
Track Volumes, Effect type and level, Style, Variation, Chord Recognition mode,
Split Point, etc.). The GK330 contains six Performances which recall factory-set
panel configurations, but you can also memorize your own Íèmbinations using the
STORE PERFORMANCE feature.
SelectingthePerformances
1. Take a quick look at the display, then press one of PERFORMANCE buttons (P1
- P6); for example, press the [P1] button.
The display shows the situation recalled by the Performance.
If you were playing in NORMAL mode, after selecting the Performance you will
find that the keyboard will be split and the mode will have changed to either
Fingered, or One Finger, to enable the Styles. You will also see a change of
Style number. For more information about how to recall Styles by selecting the
Performances, refer to the section entitled “The Styles” on page 9).
2. Repeat theselectionsfor allthe other Performancebuttons, observethe changes
in the display and play on the keyboard to listen to the change of voices.
BalancingtheLowerandUpper sections
If you are playing in Normal mode with Voices on a Split keyboard, you may at some
stage want to adjust the volume of one section with respect to the other. Using the
[MIXER] Volume controls, you will be able to balance your Upper and Lower voices
to the levels required very easily.
The MIXER consists of 5 twin buttons organized in two rows. The top row of buttons
are [INCREASE VOLUME] controls while the bottom row are [DECREASE VOL-
UME] controls. When you are playing with voices only, voice balancing tasks re-
quire the use of the [UPPER] and [LOWER] controls only. The other three controls,
(Drums, Bass and Accomp), are explained under Styles on page 11.
To increasethe volumeof, the Uppersection, forexample, pressthetop [INCREASE
VOLUME] button and hold it down until you reach the Volume required. The display
shows the Volume level of the Upper section.
To decrease the volume, press the bottom [DECREASE VOLUME] control.
If the Upper section is playing with the DUAL effect, the [UPPER MIXER] controls
adjust both voices at the same time.
