15.1 Message Classifications
Instrument SysEx operations are classified as Parameter type for send and receive of an individual parameter, and
parameter set type for bulk send and receive of a set of parameters. These SysEx types can be further broken
down into parameter categories according to the item being transferred.
The operation classification of a message is determined in accordance with the value of the "Action" field of the
PX-110/PX-310/PX-700 SysEx message. The basic format for all operation type messages is described in "15.2
Message Structure", below.
15.2 Message Structure
The PX-110/PX-310/PX-700 System Exclusive Message Format is formed of the 14 fields shown below. Whether
or not a particular field is included in a message and the length of each field depends on the message. Byte is
the minimum unit for each field length. If two values are included within the same byte, they are separated by a
slash (/).
The "act" field describes the action that the message performs. The meanings of the "index" and "data" fields
differ according to the content of the act field. The following describes each of the fields in detail.
