Checksum EOX (End Of Exclusive) Regarding the address please refer to "3. Parameter Address Map. " Regarding the checksum please refer to "4. Supplementary material. " System Realtime Message Active sensing Status FEH * This will be transmitted constantly at intervals of approximately 210 msec. 3. Parameter Address Map (Model ID = 1AH) All the numbers of address, size, Data, and Default Value are indicated in 7-bit Hexadecimal-form. A 7-bit byte can express data in the range of 128 steps. For data where greater precision is required, we must use two or more bytes. For example, two hexadecimal numbers aa bbH expressing two 7-bit bytes would indicate a value of aa x 128 + bb. Example of an Exclusive message and calculating a Checksum Roland Exclusive messages (DT1) are transmitted with a checksum at the end (before F7) to make sure that the message was correctly received. The value of the checksum is determined by the address and data of the transmitted exclusive message. How to calculate the checksum (hexadecimal numbers are indicated by `H') The checksum is a value derived by adding the address, size and checksum itself and inverting the lower 7 bits. [. . . ] In a case in which two or more messages consecutive messages have the same status, MIDI has a provision called "running status" which allows the status byte of the second and following messages to be omitted. Thus, the above messages have the following meaning.
