Basic Message Structure

System Exclusive messages that are exclusive to this Instrument are sent and received using Individual Parameter Transfer,
which gets its name from the fact that individual parameters are sent and received. A number of different messages are
provided to cover each particular operation. The field in the SysEx message that specifies the message type is the action
(act) field. The format of the "body" part of the message depends on the "act" value.
The table below shows the body format for each action of Instrument-specific system exclusive messages. An actual message
consists of the items indicated by "Y", from left to right.
