*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

There is a wide variety of messages defined under the MIDI stan-
dard, 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 re-
leased (NOTE OFF).
A NOTE ON/OFF message include a note number (to indicate note
whose key is being pressed or released) and velocity (keyboard pres-
sure 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 correspond-
ing NOTE ON or NOTE OFF message is sent from the MIDI OUT
terminal.
