Looking for that specific music mixer software...

I will try to give as much info that I can but it’s not much. I’m hoping someone here can help me out =]

The software is/was a big name in the music industry. And to celebrate their anniversary they released a free full music mixer/editor/whatnot… I think the name had “2” at the end, but again I’m not sure.

I know I’m pretty vague but it’s all description I can give and remember
