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.

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.
