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 HP 237R’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 HP 237R will no longer send out Program Change message when you change the tone being used. Also, the HP 237R 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.
