JOB  #10: LFO
FUNCTIO NSet LFO  parameters  for selecte d voice.
On  the RX7,  LFOs  (Low Frequency Oscillators)  can be used
to  alte r th e pitch  and/or  volume  of voices  for a  variety  of
effects  such as vibrato,  tremolo  or “distortion”.  The LFO
parameters  available are
1 : Frequency - determines  the speed  of the  LFO effect.
Values:  2.4, 5.6 , 6.0 , 6.4 , 6.9 , 9.8 , 48.8 , 78.1
Hz  (cycle s per second)
2:  AMD  (Amplitude  Modulation Depth) - determines
the  intensity  of the  effect on  the amplitude  (=
volume  level) of a  voice  (“tremolo”  depth).
Range:  0~3
3 : PMD  (Pitch  Modulation  Depth) - determines the in-
tensity  of the  effect on the  pitch of a  voice
(“vibrato”  depth).
Range:  0 ~ 7
OPERATIO N
1. Selec t Job  #10. One  of the  following types  of display
will  appear.
Switch  between  them with numeric keys  1, 2, 3  according
to  the  menu  written  immediately  above the PATTERN
SONG  key.
1:
Raising  the valu e increases the  cycle speed.
2.
0 indicates  no effect.  Higher values increase  vibrato intensity.
3 :
0  indicates  no effect.  Higher values increase  tremolo intensity.
Experiment  with various  settings  to get an idea of  the pos-
sibilities.
JOB  #11: POLY
FUNCTIO NSets polyphonic  number of selected  voice.
•  Range:  1 ~ 8
The  “polyphonic  number” determines  the maximum number
o f notes  that can be output  simultaneously  by one  voice.
Usually,  it is lef t at  1. Sinc e only one  note can sound at a
time  with this  setting, hitting the same  Instrument key con-
secutively will damp the previous output of that voice. During
fast drum rolls, for instance, this leads to an unnatural effect,
which  can be avoided  by raising  the poly  number.
The  poly number  value is also  set to over  1 with  instruments
such  as Brass  or DX7-Orchestra when  these are to be used
fo r chords  (harmonies).
*  The  maximum  polyphonic  number that can be set  for a
voice  depends on its  pan setting.
OPERATIO N
1. Select  Job #11 .
2 . Use  the - 1/NO  and + 1/YES  keys or DATA  slider to
input  the desired  polyphonic number.
JOB #12: EFFECT
FUNCTIO NSets effect  parameters  for selected voice.
Basically,  this Job functions  somewhat like a  combination
of  digital  delay and pitch  shifter:  it repeats the sound  2, 3
or  4  times, depending  on the Simul Number setting. (If the
delay  time is 0 and  the poly  number  is set  accordingly,  these
“repeats” sound simultaneously to form a “chord” depending
on th e pitch  settings.)  Since each  of these  repeats  can have
a  different  pitch, level or  pan setting, you can,  for instance,
have the the sound bounce between left and right channels
while playing a “melody”, or gradually recede towards the
left  background  with a rising  pitch.
With a bit of imagination and experimentation, the following
parameters allow you to create a whole host of interesting
effects.

							KEY ASSIGN
OVERVIEW
The Key  Assig n mode  lets you:
*  Assign  any voic e to  any Instrument key.
*  Assign  one voic e to  the  whole upper  row of Instrument  keys.
*  Alter  the pitch , level , pan and  decay o f voice s for  eac h Instrument  key.
*  Adjust  the accen t level s for  eac h Voice .
*  Assig n a  function  to a connected foot  switch.
*  Sav e al l Key  Assig n dat a to  on e o f four  internal memory  locations.
*  Loa d Key  Assig n dat a from  memories.
NOTE : Th e “Drum  Set” Chart  at the  end  of thi s manual  will help  you remember  your Key Assign  settings. Cop y i t and  enter
the  data for  your individua l “drum  sets”.
Pres s KEY  ASSIG N to enter  this mode . The  displa y will show the  Job selecte d last . T o specify  any other  Job, press  JOB. Th e
lower  line o f the  LCD  will as k you  to input  the number  of the  desire d Job :
Enter  the Job  number  with the numeric keys.
Data  is input  via the  - 1/N O and  + 1/YE S keys and  the DATA  entry slider
JOB #01: VOICE  ASSIGN  JOB  #02: PARAMETER ASSIGN
FUNCTIO NTo assig n any  voice  to any  Instrument keys.
OPERATIO N
1. Selec t Job  #01 .
2 . Selec t the  desire d Instrument key  by tapping  it. (Thi s
als o lets  you  chec k which  voices are currently  assigned
to  which  keys.)
3 . Use  the - 1/N O and  + 1/YES  keys and/or  the DATA
entry  slide r to  selec t the  voice  you want  to assig n to  the
key,  or input  the voic e number directly,  referring to the
Voic e Lis t in  the  BASIC  CONCEPTS  AND FEATURES
section.
* The  voice  is assigned  as soon  as it appears  on the  LCD.
Note  that all data settings  previously made for the selecte d
Instrument  key according  to the  following  Job #02 are
thereby  erased.
FUNCTIO NTo alter  the pitch,  level, pan and/or decay
o f voice s assigned  to specific  Instrument keys.
Note  the difference to alterations  made with EDIT  VOICE:
The  Parameter  Assign changes  ONLY affect the  voice as it
i s  played by the  selected Instrument  key, while  the Edit Voice
changes  affect that voic e in  all case s (i.e . also  in existing
patterns  or as played  by external MIDI  devices). Therefore,
similar  to Edit  Pattern,  the values  set with  Parameter  Assign
are  displaye d for  each  Instrument  key as offsets  relative to
the  basic  Edit Voice value.
OPERATIO N
1. Select  Job #02.
The upper  line o f the  LCD  displays the  previously se-
lected  key and its assigne d voice .
2 . Selec t the  desire d Instrument key by tapping  it.
3 . The  lower line of the  LCD  will show  any one  of the  fou r
parameters  listed furthe r below,  its key  value  and offset
to  the  basi c Edit Voice value.  Parameters are selecte d
with  numeric  keys 1 through  4 according to  the menu
marked  “*”, printed immediately  above numeric key 7.

							Example: The  MULTI LED lights  up, and  you  can now  continue
immediatel y with  Mult i Step setting  as described  below.
JOB #04: MULTI  STEP
The above display means  that th e decay value  of 1 6 for  the
selected  key is 5 units  larger  (+) than  the basi c Edit  Voice
value  of 11 . (An  offset  of 0 0 thus  indicates  that the key  value
i s  currently  identical with the basi c value.)
*  Note  that the Edit  Voice value  can only be offset  up to
its  own  minimum  or maximum.  Once this is reached,  input
o f greater  offsets will be ignored.

JOB  #03: MULT I VOICE
FUNCTIO NTo assig n a single  voice to the  upper row  of
Instrument  keys (A through  L).
Multi  Voice  assignment  makes all Instrument keys  in the
upper  row produce  the same  voice, letting  you create  a special
“keyboard”  dedicated to a single  voice for easier  Pattern
writing,  etc.. Generally,  it is meaningful  only in conjunction
with  the next  Job, Multi  Step, or  the preceding  one, Parameter
Assign.  Both may be  used to adjust the  level, pitch, pan  or
decay  for each upper row  Instrument key.
OPERATIO N
1. Selec t Job  #03.
2 . You  can now select  the voic e you  wish  to assig n to keys
A  through L  by tapping  its Instrument  key, or els e turn
the Multi Voice function off by pressing - 1/NO.
3 . As  soon  as you  assig n a  Multi  Voice , th e Multi  Step
mode  is entered  and the LCD  shows a Multi  Step display,
suc h as :
FUNCTIO NTo change  the pitch,  level, pan and/or  decay
o f the  Multi  Voice  for each  upper-row  In-
strument  key.
Th e Multi Step  function can only  be accesse d i f a  Multi Voice
i s  currently assigned  to the top-row  Instrument  keys. (See
previous  Job #03. )
With  Multi  Step, the  basic  Edit Voice  parameter  values are
offset  in equal  steps for  eac h key  from  B to  L (from left  to
right),  with key A retaining  the original  Edit Voic e value.
For  instance,  if you  choose pitch  steps o f +100  cents (=1
semitone),  each upper-row  key will sound  one semitone higher
than  the one to its  left, starting  from the  original Edit Voice
pitch  of key  A. This  means you  can then  play melodic  lines
(and,  depending on the  Edit Voic e poly number,  even har-
monies)  on the upper row of instrument  keys like on a  key-
board.
OPERATIO N
1. If  you have  just used  Job #03 , Multi  Voice,  this Job will
already  be selected .
Otherwise,  select Job  #04 .
2 . As  with Parameter  Assign explained  above, the lower
line  of the  LCD  will show any  one  of the  parameters
pitch , level , pan  or decay , along  with its  offset step  per
key .
Parameters  are agai n selecte d with  numeric  keys 1
through  4.
3 . Th e offset  step i s adjusted  with the - 1/NO  and + 1/YES
keys  or DATA  slider. The  new  value doe s not  becom e
effective  until you press  ENTER  (= START  key). Doing
s o  momentarily  displays the message “set!”.
• Ste p Ranges
Th e ste p ranges  given below are  again offsets relative to the
the  Edit  Voice  value,  which  is always  retained  by key  A.
Similar  to what  was said for Parameter Assign,  this value
can  only be  offset up to its own  minimum or maximum,  and
al l furthe r offsets are  ignored.
In  other  words,  depending  on the current  Edit Voic e pa -
rameter  values of the  selecte d Multi  Voice , certain  Multi Step
settings  may cause  minimum/maximum to be reached  by one
o f the  upper-row  Instrument  keys. All keys  to the  right  of
31 
						

							that key  will  then  sound  the same , sinc e they  are
“overstepping”  the minimum/maximum  Edit Voice  value.
I f  thi s happens, you  may want to alter the respective  Edit
Voice  parameter  value.
1: PITCH Ste p -20 0 ~  +20 0 cents  (in 10-cen t steps),
i.e. up to +/- 1 whole tone.
Setting  positive  values, e.g . +10 0 (= 1  semitone),  creates
a  scal e o f notes  that get higher  towards  the right, like
on  a piano.  Negative  values like - 20 0 ( = 1  whole  tone)
caus e the notes to become  lower towards Instrument
key  L (opposite  of a  normal  keyboard).
2 : LEVEL  Step -1 0 ~  +10
Positiv e step  value s make upper  Instrument keys sound
louder  towards  the right, while  negative step values  lower
the  volume  in that  direction.
3 : PAN  Ste p -5  ~ + 5
The  further  the Instrument  key pressed  is locate d towards
the  right,  the more  the pan  position  of the  sound  is moved
towards  the right  channel (positive ste p values)  or to-
wards  the left  channel  (negative step  values).
4 : DECAY  Step -10  ~ +10
Positive  step values make  the Multi Voice  decay shorter
towards  Instrument  key L, while negative  ones caus e
longer  decay  in that  direction.
*  Individual  settings for  all fou r parameters  can be use d
simultaneously.  Note, however, that  you will no  longer
be  able  to check  the Step value  on the  display  once you
switch  parameters with  the numeric keys.  (After switching,
the  step  is always displayed  as “0”,  regardless  of the  actual
setting.)
*  Once  you have made Multi  Step settings and exited  from
this  Job,  further  alterations  of these  values  must be  made
by  accessin g this  Job #04  directly and  NOT by first  se-
lecting  Job #03, Multi Voice.  Doing so would  erase all
current  Multi Step settings.
*  Parameter  Assign can be used  instead of or  in addition
to  Multi  Step to alter  the parameter values  individually
for  each  Instrument  key.
As  an  example,  this allows you  to create any kind of
personal  “keyboard”  with the keys A  through  L, for  in-
stance  representing  a major  or minor  scale.
JOB #05: ACCENT  LEVEL
2. Selec t th e voice  whose  Accent  you wish  to program with
its Instrument  key.
(All current Accent  levels can  be checked  by pressing
various  Instrument  keys in succession. )
3 . T o switch between Accent  1 and  2, press  the corre-
sponding  ACCENT  button.
4 . Input  the Accent  value with the - 1/NO  and + 1/YES
keys  or the  DATA  slider.
*  The  Accent  values are again  offsets which are added  to
or  subtracte d from  the Edit  Voice  level. Though their
theoretical  range is from  -63 to +63,  Accent s ar e als o
limited  by the  maximum/minimum  voice level value.  If a
voice s level  is already  set to,  say , 6 0 (i.e . 3 below the
maximum  level setting  of 63) , al l Accent  2 values over 3
(i.e . from  +3 to  +63)  give the same effect, namely  of
raising  that voice s level  to 63 when the  ACCENT  2 is
pressed.
JOB  #06: FOOT  SWITC H ASSIG N
FUNCTIONAssigns  the function  of any  front panel key
to  a  connected  foot switch .
Applications  for this function are  entirely up to your imag-
ination.  You could  assign  the voic e o f a  specifi c Instrument
key,  for instance  the Bas s Drum  of key  A, and “play” the
BD  with  an optional foot  switch. Or you  could  use the foot
switch  to add  Accents , or  assig n i t to  + 1/YES  to shift  up a
variety  of settings,  for example  selecting the next Pattern  to
be  played,  etc., etc. .
Default  setting is START/STOP , with  which  a connected  foot
switch  functions  as a  combination  of the  START  and
STOP/CONTINUE  keys.
OPERATION
1. Selec t Job  #06 . The display  will ask
FUNCTIO NProgramming  the volume  changes achieved

							MIDI
OVERVIEW
The variety  of applications  for these  functions  is enormous, letting  you use the RX7  as a state-of-the-art MIDI  sound source and
controller.  For examples,  they allow  you to:
*  Pla y any  or all RX7  voice s from  up to 16 external  keyboards and/or  sequencers by assigning  MIDI note numbers to each  RX7
instrument  and MIDI  channels  to as many  as 1 6 o f them.
*  Use  single RX7  voice s a s sound  source s for  external  keyboards or sequencers,  allowing you e.g. to  play  scale s and  chords with
these  voice s from  synthesizer keyboards.
*  Instantly  and remotely  select up  to 16 different RX7 voices  for playing  from an external  keyboard simply by switchin g MIDI
channels .
* Use  a synthesizers  pitch bend wheel  to control  pitch bend effects  for RX7 voices.
*  Play  external  MIDI source s from the  RX7 Instrument  keys according MIDI  note data output by  the RX7  on up  to 16 MIDI
channels.
*  Use  the RX7  as a  sequencer.
*  Transmit  or receiv e bulk data.
T o b e abl e to  make full use  of the  information  given in this section, you  will have  to have a  basic understanding  of the  MIDI standard.
A  guide  called “The MIDI  Book” is available from your Yamaha  dealer. Consult  this or other  publications for more details  on
MIDI.
The  rear  panel  MIDI  IN terminal  must be connected  to the external  devices MIDI  OUT for external  MIDI control  of the
