Checksum problem with sxformat

    Apr 30 2014 | 6:22 pm
    I've been trying to send SysEx messages to an Edirol SD-20 and am having problems with the checksum.
    The manual says the checksum for data 02 the checksum should = 13 = 0DH, however this is not what I am getting.
    Any help would be greatly appreciated
