Yamaha DX7 Electronic Keyboard User Manual


 
CONVENTIONS
Nearly every button on the DX7 has several functions.
Typically, the editing parameters are labeled in violet,
the overall instrument functions are labeled in brown,
and yet other functions are labeled in white or by
reversing out the color of the button. Since this manual
is not printed in full color, we have adopted the follow-
ing conventions when referring to buttons. First, even
though the button has several labels, we name only the
button label which applies to the particular step being
discussed. That button name will be bracketed to denote
a button. In addition, in many cases we actually illustrate
the button so there is no confusion as to which control
is being discussed.
Lets look at a few examples to illustrate the conven-
tions. Find the 32 numbered green buttons, and look at
the upper left corner of that area. This is how we illus-
trate the first two buttons:
Both buttons are part of a group of 6 that are labeled
in violet "OPERATOR ON-OFF/EG COPY". When the
DX7 is in the EDIT mode, this label indicates that two
different functions can be selected or activated by each
button: (a) turning the output of an operator on or off,
and (b) copying an envelope from one operator to
another. Don't worry about what this means right now;
we describe operators and envelopes and so forth later.
Suffice it to say there are multiple uses for the buttons.
To continue, when we are discussing the left button in
the context of (a) above, the printed reference to the
button looks like this: [OPERATOR ON-OFF 1]. The
same button, used in context (b), is described like this:
(EG COPY 1]. When the DX7 is in the FUNCTION
mode rather than the EDIT mode, the brown label
below it applies instead of the violet label above it. In
this case, the identical button now prepares the DX7 so
that its master tuning can be adjusted, and the text
describes the button like this: (MASTER
TUNE
ADJ.).
When the DX7 is in PLAY mode, the green buttons
serve as Voice Selectors. The label "Voice Selector" does
not actually appear on the front panel, but when the
text asks you to play internal or cartridge voice
#
1 by
pressing Voice Selector [1], the
#
1 green button is the
correct choice. As you can see, the text reference
changes to suit whichever of the button's several func-
tions is under discussion, yet the button is always illus-
trated the same way:
In EDIT mode, press the
[OPERATOR ON-OFF 1]
button once to turn off
operator
#
1 and again
to turn it on.
In FUNCTION mode,
press the [MASTER
TUNE ADJ] button to set
the [DATA ENTRY] slider
so it can alter the tuning
of the keyboard.
We alternate between showing you the complete
display window, including the LED voice number read-
out, and just the LCD portion of the display. There is no
particular signficance to this; the abbreviated display
saves space on the printed page, and when we don't
consider the voice number readout significant for an
instruction, we omit it. Similarly in some cases we

illustrate two or more adjacent panel buttons, whereas
in other cases we illustrate just one; the multiple buttons
are to help you identify the one button we are discus-
sing.
