the keys (After Touch). Velocity sensitivity is NOT set in
this mode; it is programmed into individual voices.

ALL THE PERFORMANCE PARAMETERS AFFECTED

BY FUNCTION MODE ARE MARKED IN BROWN on

the control panel. The Edit Recall and Voice Initialize

functions are also marked in brown, as are the Cartridge

Store/Load and Battery Check functions; even though
these items do not affect the sound of all the voices, they

are accessible from FUNCTION mode.

1. In order to examine and/or change the various per-

formance parameters, you first have to press the

brown [FUNCTION] button.

Press this

And you will see this

(The message on the second tine of the display could be

one of many It doesn't matter now.)

The red LED diplay will continue to indicate the

selected voice number (

8), and you can still play that

voice, but the LCD display will change to indicate that
the FUNCTION mode has been selected. As with

voice selection, the particular FUNCTION that appears

in the LCD display will be the last one selected, so we

don't know exactly what that is.

2. Press the [MASTER TUNE] button. This sets the

[DATA ENTRY] slider so it can adjust the overall
pitch of the keyboard.

Press this

The display will now look like this

Move slider up to

raise the pitch,

Move it down to

lower the pitch

3. While playing a note or chord, move the [DATA

ENTRY] slider up and down. The pitch will move

with the slider because you have selected MASTER
TUNE mode.

-or-

4. The two buttons next to the (DATA ENTRY] slider

normally serve as "fine" adjustments to do the same
thing the slider does as a "coarse" adjusment. In this
particular case, however, the slider by itself is enough

to tune the instrument since it is already programmed

to have fine resolution in MASTER TUNE mode. Tune
the DX7 to A = 440 Hz (slider approximately cen-
tered).

NOTE: This function is primarily for tuning the synthe-

sizer to other instruments. By limiting the adjustment
to a narrow range (+ 75 cents), we make it easier to
tune precisely with the slider. However, since each
voice can, itself, be programmed to a unique pitch...

or can be easily transposed (as explained elsewhere),

there is really no limit to the actual pitch you can
create when you press a given key

POLY/MONO

The DX7 is a polyphonic instrument capable of play-

ing 16 notes simultaneously This means that while you

are playing additional notes, up to 16 of them can sus-

tain at one time. As soon as all 16 notes have been
played, the DX7 will drop the first of the 16 notes when
the next one is played. Sometimes, however, you may
wish to have the instrument act as a monophonic (single

note) synthesizer... for example, when you're playing a

lead line. When FUNCTION mode is selected, pressing

the [MONO/POLY] button sets the DATA ENTRY con-
trols so you can make the choice.

1. Press the [POLY/MONO] button. This sets the [DATA

ENTRY] slider and buttons so they can toggle back

and forth between polyphonic and monophonic
modes.

Press this

The display will now look like this

unless MONO mode had last been selected in which

case the bottom line will indicate "MONO MODE".

2. If it is not already in MONO mode, set the instrument

to that mode by pressing the [>] button (or by pushing

the slider to the top) and see how the keyboard

reacts. Observe that if you hold down one key then

hit a higher or lower note, you will hear the most
recent key you press. Thereafter, the keyboard is set
correspondingly to high or low note priority until you

release all keys. There is no "fixed" low or high note

priority.

Press

this

And see

3. Experiment with moving the [DATA ENTRY] slider

up and down. Notice the display toggle between
"MONO MODE" (slider up) and "POLY MODE" (slider
down). Now try pressing the adjacent [<] and [>]

buttons. Notice they do the same thing as moving the
slider down (<) and up (>). This relationship is true

for most programming functions.

4. Set the instrument to POLY mode by pressing the [<]

button or by pulling the slider to the bottom. See how
the keyboard reacts. Observe that you can play
