Smart
The Smart type allows you to set the basic key for the chord accompani-
ment. Once this is set, you can simply press single keys in the scale and
have harmonically appropriate chords played automatically. For example,
with the key set to C, playing an D will result in an D minor chord (rather
than a harmonically inappropriate D major).
The Smart type is not only a convenient feature for easily playing various
chord progressions in a specified key, it’s also an excellent learning tool to
find out how chords relate to each other harmonically in a given key.
