Set the keyboard's MIDI options to KBD & Style. Now, hold down the A/B and ON buttons until the Harmony M's 3 LED lights begin to flash. Next, play a chord on with your left hand on the keyboard. The chord must be played below the keyboard's split point. This tells the Harmony M what channel to select for receiving the MIDI information from the keyboard. To exit the MIDI setup mode, press the A/B and On buttons until the lights stop flashing. You can find more advanced setup information on Page 20 of the Harmony M operating manual.

Because I have a relatively deep, soft voice, I set the Harmony M's Vocal Harmony settings to High and Higher. Then I set the Humanizer to the 9 O'clock position, and the Effects and Harmony to the 12 O'clock position. I set the input level to the 9 O'clock position, but this will depend upon your input source, mic, etc...

Hope this helps,

Gary
