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 system exclusive 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.
