Applying Harmony to Your Right-hand Melody (HARMONY/ECHO)
Among the Voice Effects, Harmony is one of the most impressive. It automatically
adds harmony parts to the notes you play with your right hand—immediately giving
you a more full and professional sound.
1
Turn the [HARMONY/ECHO] button on.
2
Turn on both the [ACMP] button and [SYNC START] button
(page 47) and make sure that the RIGHT 1 part is on (page 34).
3
1
Play a chord with your left hand to start the Style (page 48) and
play some notes in the right-hand range of the keyboard.
You can also use the Harmony effect with the Style stopped. Simply hold down a
chord with your left hand and play a melody with your right.
Many of the Voices have been automatically set to play certain Harmony/Echo types
that match the particular Voice. Try out some of Voices. You can also change the
Harmony/Echo type: [FUNCTION] → [G] HARMONY/ECHO.
