Controller Code 40 = Modulation Wheel

Actually, most of the MIDI control changes you will use

are already preset as controller codes 10-27. But just as an

example, let’s define controller code 40 as Modulation

Wheel. The MIDI control change number for Modulation

Wheel is 01. (see MIDI data list on page 11)

Enter PA mode by pressing the mode switch for about 1

second while in CA mode. The upper readout will show

PA.

Controller code 41 = Op. 6 Frequency Fine

Press bank A switch 11 (CONTROL CHANGE). The

upper readout will show CC.

Enter the controller code that you want to define (in

this example, 40), using the bank B switches 0-F.

Enter the MIDI control number you want. (in this

example, 01)

Enter the DATA TYPE. (0, 1 or 2) This will only apply

to Foot Switches 1 and 2. (for details, see page 00.)

For now, just enter 0.

Go to CA mode and assign controller code 40 to a

controller, for instance CS3. Then, go to PLAY mode an

try out CS1. It will perform the same function as the

Modulation Wheel.

In reality, of course, it would have been much simpler

just to assign controller code 11 (which is already preset

as Modulation Wheel), without bothering with PA mode.

The above example is for your future reference.

PARAMETER CHANGE

Use this to define a controller code as a SYSTEM EXCLU-

SIVE: PARAMETER CHANGE. System Exclusive messages

include an ID byte which is different for each manufac-

turer. So, controller codes you define here will affect only

Yamaha MIDI products. You may use Parameter Change to

change any voice parameter of the tone generating unit.

As an example, let’s try changing the Op. 6 Frequency Fine

of the DX7 (or TX).

Enter PA mode from CA mode (if you are not already

in), by pressing MODE for about 1 second. The upper

readout will show PA.

Press bank A switch 12. (PARAMETER CHANGE) The

upper readout will show PC.

Enter the controller code you want to define, using the

bank B switches O-F. In this case, let’s define controller

code 41.

The upper readout shows LM (Limit). This is where you

set an upper limit to the data number. If you check the

DX, you will find that the Op. 6 Frequency Fine has a

range of 0 to 99. So, choose a limit of 99 by pressing

bank B switch 6. (For details why, see page 00)

Now the upper readout will show G. (Group) Look in

the DX7 MIDI data list and find the group number for

the parameter you want. In this case it is 00, so enter 00.
