You can also press the selected [VOICE/UTILITY] button to

turn the program change transmit function on or off for that

button. When you turn the function off, the program change

number in the display will be replaced by a row of dashes.

4. Exit MIDI Utility mode.

Press the [MIDI] button to exit MIDI Utility mode. (If you

wish, you can return to step 2 to change other settings before

you leave this mode.)

Whenever you press a [VOICE/UTILITY] button to select a voice (other than the Dual mode sub voice), the P-100

will check the program change transmit table to determine whether a program change number has been assigned to

that button. If so, and if MIDI transmission is enabled, it will transmit the program change number in question from

the MIDI out terminal.

When the program change message is transmitted, the program change number which was sent will appear in the LED

display briefly each time you press the button to select a voice. However, you will not notice this display unless you

change the transmit table settings, since the program change number assigned to each button in the Yamaha factory is

the same as the number of the P-100 voice selected by that button.
