Connecting to MIDI Devices

Transmitting/Receiving
Sound Selection Data—
Program Change

Program Changes are messages that tell an instrument to

“switch to sound number x.”

When the other device receives this message, it will switch to

whichever of its sounds corresponds to the number

contained in the message.

When you press the ep-90/70’s Tone button to change tones,

a Program Change message with the corresponding Program

Number is sent via the MIDI Out connector. Furthermore, a

Program Change message received via the MIDI In connector

changes the tone to the one with the corresponding Program

Number.

Each time the power is turned on, the instrument will always

be set to “On” (it will transmit/receive Program Change

messages).

If you set it to “Off,” the ep-90/70 will no longer send out

Program Change message when you change the tone being

used. Also, the ep-90/70 will then ignore any Program

Change messages when that are sent to it by an external unit,

and will not change the tone it is playing.

While holding down the [Piano 1] button,

[Piano 2] button, and [Harpsichord] button,

press the “E5” note to turn the setting On,

or the “F5” note to turn the setting Off.

→ For the notes that correspond to each setting, refer to

“Functions Assigned to the Keyboard” (p. 31).
