4. You can obtain a "Full Time Glissando" effect in much
the same way (with stepped pitch shift instead of a
continuous glide); just press [GLISSANDO] and then
the DATA ENTRY [ON] button.
5. Enough work — take a fun break! Now that you've
been exposed to some of the FUNCTION control
features, try using them with other voices. You can
select any voice by pressing either [MEMORY
SELECT-INTERNAL] or [MEMORY SELECT-
CARTRIDGE] and then any voice selector button
from 1 to 32. Once you've selected a voice, press
[FUNCTION] to experiment with the Master Tuning,
Poly/Mono, Pitch Bend and Portamento functions.
When you've finished experimenting, select the "E.
PIANO 1" voice again.
NOTE The following modes should be reset as indica-
ted so that the rest of the instructions in this section
can be accomplished without confusion from any
portamento, glissando, or pitch bend effects. Press
[FUNCTION], then:
A. Return to polyphonic mode by pressing [POLY/
MONO] and then [<].
B. Turn off glissando mode, if engaged, by pressing
[GLISSANDO] and [OFF].
C. Set the portamento time to zero by pressing [POR-
TAMENTO TIME] and pulling the [DATA
ENTRY] slider down so the display indicates
"PORTATIME=0".
D. It doesn't make any difference which portamento
mode is set since, with the time at zero, there is no
effect.
MIDI
MIDI is an acronym for Musical Instrument Digital
Interface. The MIDI connectors on the back of the DX7
permit 16 channels of digital information to be shared
with other synthesizers, sequencers, and computer con-
trollers. MIDI permits two or more synthesizers to be
played from one keyboard, as well as remote-controlled
voice selection and even remote-controlled voicing
within the DX series. Voice selector button [8], the
[MIDI] button, actually selects multiple functions in the
FUNCTION mode when it is pressed successive times.
When the display shows "MIDI CH ?" you use the [<]
and [>] to select any of the 16 MIDI channels for receiv-
ing information: only Channel 1 is needed to remotely
program or play multiple synthesizers (the other chan-
nels are reserved for sequencers, computer interface and
as yet undetermined future uses). Pressing the [MIDI]
button again
shows
either "SYS
INFO
AVAIL"
or "SYS
INFO
UNAVAIL",
depending
on how you
press
the
[YES] and [NO] buttons.
"SYS
INFO
AVAIL"
enables
you to program other
devices connected by MIDI cable — to send every
parameter for one voice or all 32 internal voices from
the Master to the Slave, and you can also select and play
voices on the Slave(s). To send all 32 voices to another
DX7
(or 20
of
them to
a
DX9),
once
"SYS
INFO
AVAIL"
is
displayed, press the MIDI button [8] again and, when
the display asks "MIDI TRANSIT?" press the [YES] but-
ton (memory protect must be OFF in the other synthe-
sizer). Individual voices or parts of voices can also be
transferred. If you set the instrument so it displays "SYS
INFO UNAVAIL," then you can change programs (select
different voices) and play the Slave from the Master, but
you cannot transfer voice parameters from one instru-
ment to the other.
EDIT RECALL
This function is used as an "emergency backup" to
recall a voice that was "lost" while it was being edited or
created from scratch. Please do not press this button
right now; if you already have, just press [NO] or an-
other FUNCTION button, like [BATT CHECK]. This
button's operation is described in the "FUNCTION
Mode" portion of the "Quick Basic Features" section of
this manual. See page 9.
VOICE INTT (Initialize)
This function is used to create a new voice "from
scratch," and pressing it is the first step of an alternative
method of entering the EDIT mode. Please do not press
this button right now; if you already have, the display
shows "VOICE INIT?"; press [NO] or any other FUNC-
TION button to cancel the mode. This button's operation
is described in the "FUNCTION mode" portion of the
"Quick Basic Features" section of this manual. See page
9.
CARTRIDGE FORMAT
Voice selector button [11] serves a special purpose in
the FUNCTION mode. Pressing this button selects the
cartridge FORM (format) function. Formatting erases all
the voices in a RAM cartridge. Don't experiment with
this feature unless you're willing to loose the voices on
the RAM. Instead, read the description in the "FUNC-
TION mode" portion of the "Quick Basic Features" sec-
tion of this manual. See page 9.
BATTERY CHECK
The battery backup preserves the internal RAM voice
memories when the AC power is turned off. The normal
battery voltage ranges from 2.3 to 3.5 volts. If the battery
voltage is too low, the synthesizer will operate normally
but any voices in the internal memories may be lost or
altered when power is turned off. Therefore, it is advis-
able to check the battery voltage prior to turning off the
instrument and, if it is low, be sure the internal voices
are saved on a cartridge. (Refer to page 49 for instruc-
tions on storing your voices in the RAM cartridges.)
Press the [BATTERY CHECK] button and examine
the voltage. If it is below 2.2 volts, the battery must
be replaced; if it is over 3.6 volts, something may be
wrong with the DX7.
The voltage should be between 2.3 and 3.5
CAUTION The battery is a long-life Lithium
type, and when it is exhausted (below 2.2
volts) it must be replaced by your Yamaha
dealer. Be sure you save any internal voice on
