Note1 The PX-150,PX-750, AP-250, and PX-350M do not support Note Off Velocity. For these models, Velocity for send
Note Off messages is a fixed value (40H). The High Resolution Velocity Prefix message is not sent for a Note Off message.
Receive Receipt stops a note being sounded by a note on message. (Note1)
When a High Resolution Velocity Prefix message is received immediately prior to the Note Off message
and the lower seven bits of the 14-bit Velocity are set, the 14-bit resolution note off of the note being
sounded is performed.
For information about the relationship between the Note On/Off message and High Resolution Ve-
locity Prefix message, see "4.3 Instrument Velocity Resolution".
Note off by making the Note On Velocity 00H is identical to note off by the combination of High
Resolution Velocity prefix message 40H and Note Off Message 40H.

function is enabled when the Instrument is turned on, and disabled by receipt of a Note Off message with a Velocity value other
than 00H.
