Channel Message; Note Off; Note On - Casio PX-S1100RD Manual

Part II

Channel Message

Instrument Note On Velocity Resolution The upper seven bits of the 14-bit resolution correspond
to the Note On message, while the lower seven bits correspond to the High Resolution Velocity Prefix
message.

Note On

Upper 7 bits
The initial default value for the lower 7 bits is 00H. Receipt of a High Resolution Prefix message
causes the lower seven bits to be set, but note on is not performed.
Receipt of a Note On message causes the upper seven bits to be set with note on performed with
14-bit resolution Velocity.
The High Resolution Velocity Prefix message corresponds the message immediately following the
Note On message, and the lower seven bits are cleared to 00H immediately following note on by the Note
On message. 7-bit resolution note on using only the Note On message also continues to be supported.
For details about each message, see "6 Note On" and "7.20 High Resolution Velocity Prefix".
