Filter Plug-In for soundshaping

Hello,

I am using ableton's Auto-Filter a lot recently to shape and sculp sounds.

But when I compare it to the filter of a few of my plug-ins, especially Omnisphere, I find that it obviously lacks a lot of features. Are there any filter plug-ins, commercial or free, that you can recommend that include the following features?

- different types of filters (12db, 24db etc.)
- a "key" sensitivity-option (the cut-off value is not absolute but has a certain relativity to the midi-note being played)
- obvious features such as different waveforms for the lfo
- sidechaining

When I compare Omnisphere's filters I realise that a filter is not a filter. They can sound very different. But since I can only use Omnisphere's filters inside the Omnisphere instrument, I would love to use a plug-in that has a lot of different filter types with lots of options.

Thanks for any advice/tips!

P.S. I've been reading on these forums for a long time, and this is my first post!
