INSTRUCTIONS FOR MIDI INTERFACE
YAMAHA CS-70
USING THE MIDI INTERFACE - - -
When you turn on the synthesiser for the first time, you will be in
omni-on mode for receive (all channels) - selecting a receive channel
will also set omni-off. See next page for factory default settings.
When you select a receive channel, this will be stored in memory and
will be remembered for when you subsequently turn on the synth - all
parameters listed on the next page are stored.
If you want to put the machine back to the factory default settings
at any time, switch the synth on whilst holding the red push button
pressed - hold for a couple of seconds then release.
RED PUSH BUTTON
Two modes are available by pushing the red push button.
1) SET-UP MODE - Setting MIDI channels and assignments.
Give the red push button one short press (half a second) - then release.
Follow this with a note or sequence of notes (on remote synth) as given
on page 2. After selecting a channel you will be automatically returned
to playing mode but after making assignments you will need to press the
ENTER key (Top C) to return to playing mode. This is to enable you to
make the multiple key presses required when re-assigning sources to
destinations. (N.B. set-ups are stored in non volatile memory).
2) TRANSPOSE MODE -
Press and hold the red push button for four seconds - then release.
Middle C will sound on the synth and continue to sound until you
press a key (on the remote synth). The note that you press will be the
new middle C for MIDI IN. You can set any value up to two octaves up or
down. Settings outside this range will be ignored. Note that transpose
mode cannot be entered from program mode. [Transpose is not stored]

NOTES
1) Controller X can be any MIDI controller.
After pressing the red push button twice to enter SET-UP mode,
operate the required MIDI controller before pressing the C or
Db key that will assign it to VCF or ***.
If you do not operate a controller before pressing the C or
Db key, then controller X will respond to MIDI controller
16 - that is General purpose controller 1 (10 hexadecimal)
2) Controller Y can be any MIDI controller.
After pressing the red push button twice to enter SET-UP mode,
operate the required MIDI controller before pressing the A or
Bb key that will assign it to VCF or ***.
If you do not operate a controller before pressing the A or
Bb key, then controller Y will respond to MIDI controller
17 - that is General purpose controller 2 (11 hexadecimal)
3) Controller X/Y will take priority over other control messages,
so if controller X/Y is the mod wheel, mod wheel messages will
operate whatever controller X/Y is currently assigned to,
instead of operating modulation.
4) Receive channel and omni-on setting will return you directly to
playing mode, all other keys will let you stay in SET-UP mode
until you press the ENTER key (Top C)
5) The ENTER key (Top C) also resets all controllers to their
default values - off in most cases - on for volume - centre
for pitch bender.
6) After pressing the red push button twice to enter set-up mode,
the first assignment that you make for any given source (after-
touch for example) will cancel all other destinations currently
assigned to that source - if you want to make multiple assign-
ments, you will have to do this in the same set-up session, in
other words, before you press top C.
- For example - irrespective of what aftertouch was previously
assigned to, pressing F (and release) will assign it to VCF only
- to make aftertouch also bend pitch, you will have to press E
( and release) before pressing the top C which will ENTER the
information and store it in n.v. memory.
OTHER SET-UPS WILL REMAIN UNALTERED UNLESS SPECIFICALLY CHANGED
7) Control change commands recognised - (numbers in decimal)
121 reset all controllers 01 modulation wheel
123 all notes off 07 Main volume
124 omni mode off (always poly) 64 sustain pedal
125 omni mode on (always poly) 65 portamento
126 (mono mode) = all notes off 94 select transpose mode
127 (poly mode) = all notes off 95 select set-up mode
nnn Controller X (user defined where nnn = any controller)
nnn Controller Y (user defined where nnn = any controller)
N.B.- Controller X default = 16 : Controller Y default = 17
8) Other commands recognised - (numbers in hexadecimal)
8nH notes off 9nH notes on & velocity
BnH control change (see above) CnH program change
DnH channel pressure (aftertouch) EnH pitch-bend change
FEH active sensing

MIDI CONTROL OF RED PUSH BUTTON
The red push button can be "pressed" via MIDI as MIDI switch number
95 (5Fh) for regular program mode or 94 (5Eh) for transpose mode.
The selection of the push button is enough, it doesn’t matter if it
is being turned on or off.
In hexadecimal BX - 5F - 00 = program mode
In hexadecimal BX - 5E - 00 = transpose mode
Where X is the current MIDI channel.
[n.b. whilst in program/transpose modes the MIDI is in omni on mode]
MIDI CONNECTORS - -
MIDI IN should be connected to a MIDI OUT or a MIDI THRU
similarly MIDI OUT should be connected only to a MIDI IN
and a MIDI THRU should also be connected only to a MIDI IN.
MIDI OUT is the signal from the synthesiser (or drum machine etc.)
that is to be sent to another instrument. MIDI IN is a received
signal that contains MIDI information from another synth, and MIDI
THRU is an exact copy of information arriving at the MIDI IN socket.
This allows several instruments to be connected together.
If you want to wire your own MIDI cables the following information
may be useful.
1) Although a 5 pin connector is used, only two connections plus an
earth connection are required.
2) If you look at the din plug from the wiring side you will see
that the pins are numbered. From left to right (or clockwise) these
are 1 - 4 - 2 - 5 - 3.
3) The pins numbered 1 & 3 are not used.
4) The screen (earth) is connected to pin 2 (centre pin)
5) Pin 4 of one plug should be connected to pin 4 of the other
6) Pin 5 of one plug should be connected to pin 5 of the other
7) You should now have a working MIDI lead
8) It is preferable to label one end of the cable MIDI IN & the
other end MIDI OUT, to avoid confusion.
