*1 Sustain
With piano tones and other sounds that decay, the pedal acts
as a damper pedal, with sounds being sustained longer when
the pedal is depressed. With organ tones and other continuous
sounds, notes played on the keyboard continue to sound until
the pedal is released. In either case, the sustain effect is also
applied to any notes that are played while the pedal is
depressed.
*2 Sostenuto
This effect performs the same way as sustain, except that it is
applied only to notes that are sounding already when the
pedal is depressed. It does not affect notes that are played
after the pedal is depressed.

Messages
The MIDI messages explained here can be sent and received
when the keyboard is connected to a computer by USB
connection. Note, however, that you need to install the USB
driver from the CD-ROM that comes with the keyboard on
your computer to send and receive these MIDI messages.
There is a wide variety of messages defined under the MIDI
standard, and this section details the particular messages that
can be sent and received by this keyboard. An asterisk is used
to mark messages that affect the entire keyboard. Messages
without an asterisk are those that affect only a particular
channel.
NOTE ON/OFF
This message sends data when a key is pressed (NOTE ON)
or released (NOTE OFF).
A NOTE ON/OFF message include a note number (to indicate
note whose key is being pressed or released) and velocity
(keyboard pressure as a value from 1 to 127). NOTE ON
velocity is always used to determine the relative volume of
the note. This keyboard does not receive NOTE OFF velocity
data.
Whenever you press or release a key on this keyboard, the
corresponding NOTE ON or NOTE OFF message is sent from
the USB port.

NOTE
• The pitch of a note depends on the tone that is being
used, as shown in the Note Table on page A-1. Whenever
this keyboard receives a note number that is outside its
range for that tone, the same tone in the nearest
available octave is substituted.
