Checking the message. Device A sends a DTI message back to Device B. Device (A) Device (S) [Data set t] «I ■ ■ — [Data set 1] —........................ * More than 20m sac time internal. [Data set S] -■■■........ [Dats set 0 —..........;-► -[Request cfata] The MIDI standards inhibit non-real time messages from interrupting an exclusive one. This fact is inconvenient for the devices that support a “soft-through* mechanism. To maintain compatibility with such devices, Roland has limited the DT! to 256 bytes so that an excessively long message is sent out in separate segments. Byte sum F7H Description FOH Exciusive 41H Manufacturer ID (Roland) DEV Device ID MDL Model ID 12H Command ID aaH Address MSB LSB Data Check sum End of exclusive * A DT! message is capable of providing only the valid data among those specified by an RQ! message. * Some models are subject to limitations in data formal used for a single transaction. Requested data, for example, may have a limit in length or must be divided into predetermined address fields before it is exchanged across the interface. * The number of bytes comprising address data varies from one Model ID to another. * The error checking process uses a checksum that provides a bii pattern where the leasi significant 7 bits are zero when values for an address, size, and that checksum are summed.
