Format
Message Format: BnH 54H vvH

kk: Source Note Number
Send This message is not sent by this Instrument.
Receive Receipt of this message first stores the Source Note Number for the next note. When the
next Note On is received, the portamento effect is applied to the note using this Source Note Number as
the pitch start point and the Note On event key number as the end point. If there already is a note being
sounded by Source Note Number at this time, the new note on is not performed and the portamento
effect is applied to the pitch of the note being sounded. That is to say that legato play is performed.
