When you press multiple keys, there
are notes which are not sounded.
Depending on the mode (Auto
Accompaniment, Vector Synth, etc.),
the amount of notes voiced are
different.
Don't worry, you can play up to 28
notes simultaneously in Normal
mode.
You are playing with a Voice which
consist of some notes. As you make
a combination of Voices with the
Vector Synthesizer, some preset
Voices are made of several notes.
For example, with a Voice made of 4
notes, you can play up to 7 notes at a
time (4 by 7 equals 28: maximum
notes).
This is not a problem. Lessen the
notes you play at a time.
