Two things:
1. There is already a cracked version of Korg Legacy Collection
2. I attended a demo of these synths and I was very impressed with the sounds quality. Although I've never used a real MS-20 or Polysix, their software emulations sound better than any other soft synth I have heard so far. I was especially impressed with MS-20's bass sounds, in a nutshell - gut-wrenching! Isn't that how we like them?
