Sysex Checksum

Post by asdvw43 »

Sysex checksums are used in music device data, one can request or send sysex data both ways, Computer<->Device

Portions of data must have a sum counted for a generated 7-bit checksum to pass inside the device

Sysex 7-bit Checksum:

CSM = 128 - (sum Mod 128) And 127

' sum would be sum of selected bytes from document, not a count
