Hello
I know this is a stupid question but just double checking..If i install Reason 3.0 will all my sounds and refills from 2.0 still be there or will it be wiped clean?
Thanks

If you're talkin' about your own presets —i mean, the sounds that you've created— you should't be worried, your files are one thing and the application files are another completely differents.
And if you're refering to the app sounds, well, it seems like Propellerhead love to create a huge collection of sounds, i mean that they don't exclude past sounds in new versions, they just add, never substract. I hope this can help you.

I forget to say: if you made a change in the original sound and save it like the original, obviously, when you reinstall, i think, the changes will be lost. In other hand, i remember that you can't replace the original sounds from the refill folders
