For example, if you want to lower the pitch by 2 notes (two half-steps or a whole step), press the MIDI/SELECT button then the “flat” key twice. Press the MIDI/SELECT button to finish the change.

Octave Keys: To change the Radium’s octave range, press the OCTAVE UP or OCTAVE DOWN button, according to your preference.The octave shift range available includes a maximum increment of plus or minus three octaves and the display will read “-3”,“-2”,“-1”,“0” (for default),“1”,“2” or “3”, corresponding to the setting currently selected.

MIDI CHANNEL Key: By pressing the MIDI/SELECT button, then pressing the MIDI CHANNEL key, you select your keyboard’s transmitting MIDI channel.The default channel will be 1 when the Radium’s power is first turned on.To change this setting (for example, to set MIDI channel to Channel 2), do the following:

2.Press the MIDI CHANNEL key.

3.Press the “2” key, then the Enter key. Lastly, press the MIDI/SELECT button one more time (this will change the MIDI transmit channel from 1 to 2.)
