Doc, thou art correct.
Go to
http://www.access-music.de
...and download OS v6.5 for Virus C/KC series. You will magicly be awarded Banks E-H.
They're pretty good, some repeats, some new, some interesting tweaks of old favorites.
If you're using PC the just set your system to use your MIDI interface and play (Open) the MIDI file/OS update from the Access site in Windows Media PLayer (while your C/KC is attahced to your PC/MIDI interface).
The Virus will blink...it will tell you not to touch it...be patient...the blinking lights will stop...now you 512 more presets and NO DEMO SONG!!!
Good luck, and enjoy!
