INSTRUCTIONS FOR MIDI INTERFACE
YAMAHA CS-50 & CS-60
USING THE MIDI INTERFACE
When you turn on the synthesizer for the first time, you will be in omni-on mode for receive (all channels) - selecting a
channel will select 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.
SWITCH
The switch on the control panel is to route the CS-50/60 sub-oscillator through the Mod Wheel or Aftertouch - in the up
position the CS-50/60 will be as normal - in the down position, the appropriate destination can be selected on the CS50/60 but no effect will be noticed until the MIDI Mod Wheel is advanced or aftertouch is used.
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 each) - then release.
Follow this with a note or sequence of notes as detailed 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. 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.
ASSIGNING MIDI CONTROL SOURCES TO DESTINATIONS
SOURCES DESTINATIONS (d)=factory default
AFTERTOUCH off / modulation / p.bend / vcf / CS50/60 after-touch (d)
CONTROLLER X off / vcf (d) / not used
CONTROLLER Y off / vcf / not used (d)
VELOCITY off (d) / vcf / vca
MIDI VOLUME off / vca (d)
Sources can control more than one destination at once, but a destination can only be controlled by one source at a
time. Thus if velocity is currently controlling VCF and then you switch aftertouch to VCF, velocity will then control nothing
until re-assigned.

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) 0
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 SETUP 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 assignments, 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) 94 select transpose mode
126 (mono mode) = all notes off 95 select set-up mode
127 (poly mode) = all notes off
nnn Controller X (user defined where nnn = any controller)
nnn Controller Y (user defined where nnn = any controller)
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 synthesizer (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.
