If you want all the old programs for the K2000 go to: ftp://ftp.funet.fi/pub/sci/audio/instruments/k2000/
If you can't find the GM disk, I think I have it on the hard drive of my K2000s. I will need your email address. The people at godlike are great people. They used to be Mastering VAST. I've learned a lot from those guys.
