Anyone knows any Saturation plugins to suggest to try out?
Also what Saturation plugin are you using and why?
Lets start discussing about Saturation.:p

What kind of saturation are you looking for? What are you going to use it for?

Anyway some good allround freeware ones are VoS FerricTDS, TesslaPro mkii, voxengo tube amp. I don't really use that many dedicated saturation plugins, I mostly use analog EQ/channel/compressor/whatever simulations that have some sort of saturation going on in them.

There isn't any freeware stuff that I particularly recommend the saturation on, however BootEQ mk III has a good saturation section, and roundtone, for the price, is wonderful.
The best tape effect I've used is VTM, but that's pricey. However roundtone does some stuff vtm doesn't, both're worth purchasing.

Sknote Grasso is amazing , also the saturation in Cytomic Drop filter is amazing too ! For real tape sound uad studder and roundtone !

I use a tape sim plugin on every bus, every time. At least I have for the last few years. Kramer Tape is usually my first pick but I'll use Nomad Factory's Magnetic II, Tonebooster's Reelbus or SKnote's Roundtone as the situation or CPU load dictates. I tend to add them after I've achieved an acceptable mix then tweek to suit.

I regularly use
free
Variety of Sound's several plugs that have saturation sections
why, they combine saturation with compression
paid
Toneboosters Ferox and Reelbus
why, quality
Melda Prodcutions multiband saturator
why, flexibility, quality

Fabfilter Saturn and Sknote Roundtone are the favorites that I have tried. Both offer high quality oversampling for a true analog experience.

Roundtone (especially the newest version) is MONEY. Love that shit.

This one is only about tape drive (BootEQ emulates a tube sat not a tape sat)

You can also try Ferrics from Variety of Sound (tape drive plus tape dynamic), Roundtone and Reelbus are amazing (and cheap) and VTM is definitely a jem.

Fabfilter Saturn is great for saturation.

Reelbus is nice too.

I am using waves mpx tape, fabfilter saturn and sknote roundtone the most. Aphex aural exciter also is nice.

What are you trying to achieve ?

You killed me, I though it was out .

But no, still mkII over here.

One or more of the following plugins are used in our projects when we want some character introduced.

Slate VCC
Slate VTM
Soundtoys Radiator

Another good saturation plugin is FXpansion Maul.

It would be nice if the GUI was re-sizable since it takes up a lot of space.
