There's Serum, Sylenth, Omnisphere.. I mean the list really goes on and on when it comes to synths, sounds, etc. Then there's Komplete, Native Instrument's flagship production suite. As far as I'm concerned, this is the one to start with and make the cornerstone. I'm still using 9 and learning more every day. I'm certain 11 is everything I expect it to be and with an intro rate of $199, it's more affordable than ever. This isn't a sales pitch, I just really like the product so I'll just shut up and let you click the link and find out for yourself. Enjoy!
