user’s guide
A tone’s quality and
volume sounds
slightly different
depending where it is
played on the
keyboard. This is an unavoidable result of the digital sampling process, * and does not indicate malfunction.
* Multiple digital samples are taken for the low range, middle range, and high range of the original
musical instrument. Because of this, there may be a very slight difference in tonal quality and
volume between sample ranges.
When I press a
button, the note that
is sounding cuts out
momentarily or there
is a slight change in
how effects are
applied. This happens when the sounds of multiple parts are sounding at the same time while using layer,
using the Duet Mode, playing back a built-in tune, recording, etc. Pressing a button when one of these
conditions exists will cause the effect setting that is built into the tone to change automatically, which
causes the notes to cut out momentarily or causes a slight change in how effects are being applied.
