Instrument-Specific System Exclusive Messages

16 Format

This section explains the format of the Instrument-specific System Exclusive Messages. See “Part V Parameter List” for information about what type of data can actually be sent.

16.1Message Classifications

Basically, the operation that corresponds to Instrument-specific system exclusive messages is parameter data transfer. The following operations can be performed from an external device using this parameter transfer message.

•Modification of an individual Instrument parameter

•Import of an individual Instrument parameter value

In addition to parameters being used as device setting values, some parameters act as commands when received by the Instrument and as device status information when sent from the Instrument.

The following table shows the parameter category for each type of transfer.

16.2Basic Message Structure

Since Instrument-specific System Exclusive messages are sent and received on an individual parameter basis, the Individual Parameter Transfer method is used, and a number of message types are provided to suit specific operations. 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.
