I am new to the forum. This is my first post with a question on the 2480. I just bought a 2480cd. I decided to upgrade it to the latest download from the Roland site. I did the midi upgrade and followed the instructions. It worked and the system and boot were upgraded to 2.505. However when I ran test mode I noticed that the Sub System is 1.000. Is that normal or is there another upgrade. Also I got a message the the SPC version does not match. I searched for SPC and can find nothing referring to that or to the subsystem upgrade. everything else tests fine. Is there a fix to these two issues? Thanks for any information.
