Want to buy Wavelab 6

That’s it!
I can’t find it anywhere.

You can buy Wavelab 8 full version, and then download Wavelab 6 (i assume you want the full version of Wavelab 6). The full version Wavelab 8 license will support full version Wavelab 6.

Wavelab 6 available on the downloads page, under “Unsupported Products”:
http://www.steinberg.net/en/support/downloads.html

Then you have Wavelab 6 and Wavelab 8 on the same machine (with all the other stuff Wavelab 8 has, like DDP, etc).

Don’t know about lesser versions (like elements, essential, etc)

thanks, bob99!
