I have the PC version, now. I found a place to download it from (wink - wink) so it's not impossible to get.
I'd still like to get an "actual" copy. I remember seeing them in the $10 bin at Wal-Mart a few years ago, but my PS2 was still working, then, so I didn't feel like I had a need for it. Now, I wish I'd have just bought it, anyway.
It's been a few years since I've used the PS version, so a lot of the intricate details of how to use it elude me, now. I've tried to use the PC version, a couple of times, but it doesn't "feel" right, for some reason. One would think that using a mouse would be more intuitive than a game controller, but it, somehow, seems more difficult. I'm going to keep plugging away, though, because I really miss being able to create music. I've tried other app.s, like Fruity Loops, but they are much too convoluted and just getting a simple drum beat takes far too much effort, especially when compared to the ease-of-use you get with the Generator.
