I just installed a Korg EXB M256 memory expansion board which shows up in the M3 Expanded start-up screen as installed, and also shows up as 100% free under RAM2 on the Media/EX-USB PCM tab.
I'm trying to load EXPCM01 - 4 (from the internal SD card), but when I highlight them and press Load, I just get a message that says "No medium".
Please does anyone have any pointers? I can't find an answer by searching the forum.
**Update** Since posting, I think the M3 is trying to load from a non-existent USB drive. Do I need to point the system to the internal SD card? (P.S. I tried downloading the EXPCM01-4 files from Korg but the links seem to be dead

Thanks in advance!
Mark.
