RD-300NX: Transposing the Keyboard
Use the following procedure to transpose the RD-300NX.
1. Press and hold the TRANSPOSE button.
2. While holding the TRANSPOSE button, use the DEC and INC buttons to transpose the keyboard in half-step increments by as many as 48 semitones up or down.
Note: To turn the Transpose feature off, press the TRANSPOSE button so it's not lit. To return to your previous Transpose settings, press the TRANSPOSE button so it lights again—the RD-300NX remembers the Transpose setting until you power down.
