Part IV Instrument-Specific System Exclusive Messages 19 Format This section explains the format of the Instrument-specific System Exclusive Messages. See "Part V Parameter List" and "Part VI Parameter Set List" for information about how parameter sets actually are transferred. 19.1 Message 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 • Batch modification of a particular Instrument parameter set • Import of an individual Instrument parameter value • Batch import of a particular Instrument parameter set 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.
