Channel Message

Instrument Velocity Resolution The upper seven bits of the 14-bit resolution correspond to the

Note On/Oﬀ message, while the lower seven bits correspond to the High Resolution Velocity Preﬁx

message.

Note On/Off High Resolution Velocity Prefix

Upper 7 bits

Lower 7 bits

14bits

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 p erformed.

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/Oﬀ message, and the lower seven bits are cleared to 00H immediately following note on by the

Note On/Oﬀ message. 7-bit resolution note on using only the Note On/Oﬀ message also continues to be

supported.

For details about each message, see ”5 Note Oﬀ”, ”6 Note On” and ”7.20 High Resolution Velocity

Preﬁx”.
