Instrument-Specific System Exclusive Messages

16 Format

16.1 Message Classifications

The SysEx operation of this Instrument is basically a parameter data transfer operation. The following operations can be

performed from an external device using this parameter transfer message.

• Change of a specific Instrument parameter value

• Batch change of multiple Instrument parameter values

• Import of a specific Instrument parameter value

• Batch import of multiple Instrument parameter values

Parameters can be used for more than just device setting values. There are parameters when writing data that operate as

commands, and parameters when reading data that indicate the status of the Instrument. The following table shows the

parameter category for each type of transfer.

16.2 Basic Message Structure

Instrument-specific system exclusive message operation can be broadly divided between two methods: Individual Parameter

Transfer (single parameter send/receive) and Bulk Parameter Set Transfer (batch parameter send/receive). Each method

includes a number of different messages. 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.
