Equal loudness contours for bass EQ, Also useful for mix correction.

NyquistEq is a paragraphic equalizer that does not suffer from the treble warping that most digital equalizers do. Also it never clicks, and it handles deep bass well.

The reason it's called NyquistEq is because it's designed to be a filter that sounds good all the way up to the Nyquist frequency (if sampling rate is 44.1 kHz then nyquist is at 22.05 kHz).

Parametric EQ is a powerful 10 Band EQ Plug-In offering much more than what is found in traditional parametric EQs. Parametric EQ features 7 fully configurable bands and 3 additional bands, which are controlled by a unique virtual joystick for simultaneous and fast Treble and Loudness control. The 7 bands can be assigned to work as Parametric, Hi Shelf, Lo Shelf or even Notch filters – and any combination of these. Split gain controls for left and right channels give you instant access for working on channels discreetly, or moving the frequency spectrum around in the stereo image.

Very nice and easy to use 4 band parametric equalizer. Soft limiting is applied to its output.

FLOORFISH is a simple expander / gate device, easy to set up and offers a broad variety of processing, ranging from slight expansion, backgound noise attenuation to extreme gating effects.
What's different from similar units is the ability to scan the source and adjust the transistion curve accordingly.

Neon Gate is an easy to use host synchronized FX insert, which is ideal for "Trance" style rhythms.

Tom BandPass is a simple band pass filter. Sometimes you just want a simple, highly efficient filter that sounds good. If that's what you want, then this is your filter.

The Classic Auto-Filter is an analog modeled four-pole filter with resonance control. It can be used for creative effects like auto-wah-wah and filter sweeps, as well as a fixed filter for equalizing purposes. The filter is selectable between low-pass, high-pass, band-pass and band-reject (notch). The filter cut-off frequency can be modulated from the envelope follower and the LFO.
