Points to Remember
The inverted forms of chords (in the case of a major
chord for instance 3—5—l and 5—l—3, etc.) are also
recognized.
Any combination of notes other than those listed above
is ignored.
In the case of augmented and diminished chords, the
lowest note played on the keyboard is considered to
be the root of the chord.
Sixth chords are distinguished from minor sevenths
as follows: If the lowest key played is the root of the
sixth, the PortaSound considers the chord to be a sixth
chord, while all other key combinations produce minor
sevenths.
In a similar manner, seventh flat-five chords are dis-
tinguished from minor sixths according to whether the
lowest note played is the root of the sixth (in which
case the chord is considered a minor sixth) or not.
With seventh flat-five chords, the lowest key played
is treated either as the root or the seventh.
Overview
By using the Duet feature, you can have the PortaSound
automatically perform a second voice that harmonizes per-
fectly with any solo part you play in the MELODY SECTION
of the keyboard. This gives the impression of a duet (a per-
formance with two instrument parts), even though you are
playing only one part yourself.
To be able to use Duet, the PortaSound must be set to one
of the AUTO ACCOMPANIMENT modes (Single Finger
or Fingered).
Operation
1. Select SINGLE FINGER or FINGERED mode (3a).
2. Press the DUET button (7).
Its red indicator will light up. The PortaSound is now ready
to perform an automatic Duet.
3. Start Auto Accompaniment or play Single Finger Chords.
Once an Auto Accompaniment is playing (or a Single
Finger Chord is pressed), any melody lines you perform
with your right hand will automatically be accompanied
by a second voice in harmony with the accompaniment.
(The sound of this second voice is that of the currently
selected instrument.).
Points to Remember
With the Duet function on, the MELODY SECTION
is monophonic — only one note can be played at a time.
If more than one key is pressed simultaneously, only
the highest one will sound.
Pitch bends and portamento can be used with Duet.
Duet has no effect on SONG MEMORY MELODY
playback.
The Duet sound data is all output on the same MIDI
OUT channel.
Duet works even if the entire Auto Accompaniment
ORCHESTRATION is turned off. This lets you play
a duet without any accompaniment sounds.
Duet is canceled if a melody memory is turned on for
recording.
