Well, '05' should ONLY be used as the byte position to start the
checksum addition if the Roland "Model" specification is exactly 1
byte long: for a 2-byte model (e.g. my GS-10 has "00 63") this should
be '06'. I guess the very latest Roland model IDs are 3 bytes long
("00 00 xx") - for those it should of course be '07'.
