Latticereverb

LatticeReverb is a reverb using lattice structure. Equipped with 16 delays per channel.
Lattice Reverb is based on a reverb algorithm which uses the all-pass filter lattice topology and a delay grid with sixteen all-pass filters per channel. That’s the technical part of it, and I have to admit that I don’t understand any of it. The bottom line is, Lattice Reverb is a reverb plugin that uses some advanced mathematical algorithms to process sound.

The types of effects you can achieve with Lattice Reverb range from glitchy echoes and pitch-shifted delays to huge dark reverb and pure chaos. You can get some totally crazy sounds out of it.

twinPhaser

twinPhaser it's a double (left and right channel) phasing effect . Very low resources taken.

• Two channel settings for left and right.
• Frequency, rate, depth, feedback and mix amount for each channel.
• Enhancement effect by channel with accent for left, right or balanced.
• Pan mirror for symmetrical balancing.
• Bypass the plugin up to an audio signal threshold. Set this threshold on the bottom-right corner.
• Few presets.

SaschArt ReverseDelay

ReverseDelay offers three delay controls – Pan Width, Feedback, and Frequency. Dry and Wet signals can be mixed independently, and the Delay Rate parameter can be specified precisely with note length and Normal, Dotted, Triplet, or host tempo sync options.
The plugin’s user interface is minimalistic in design, and it consumes “extremely low” system resources.

vMPC2000XL - An MPC2000XL emulator

vMPC2000XL plugin is a close emulation of the Akai MPC2000XL sampler. The software doesn’t emulate the signal path of the original hardware, so it doesn’t color the sound per se. However, it simulates the MPC’s digital voice filter. According to the info provided by the developer, this aspect of the emulation was “tweaked by ear” to resemble the hardware as closely as possible. On the other hand, the internal circuits are not emulated, so the samples won’t sound different simply because you’re playing them via this plugin. 
More importantly, though, vMPC2000XL closely recreates the workflow of the Akai MPC2000XL hardware. Every menu screen and software feature is modeled after the original instrument. As a result, you’re getting an authentic Akai MPC2000XL experience in software format.

Moss Equalizer

Moss Equalizer works with FFT (Fast Fourier Transform) algorithms and is capable of steep frequency adjustments – from -150dB up to +60dB in the frequency domain of 10Hz to 20kHz.

With such a wide range for adjustments, the Range control in Moss Equalizer is particularly helpful. It lets you specify the minimum and maximum amplitude manually, in dB. Furthermore, the FFT algorithm can be adjusted manually as well with the provided FFT Size control.

Below it, you can choose a visual theme for the interface. Other options include Logarithmic Level and Spline Curves display, a Limiter, a Bypass switch, and a Dry/Wet mix knob for blending dry and equalized signals to taste.

An exciting feature we rarely see in other equalizer plugins is the comb filter modeling. Dialed in purposefully, it is capable of creating a vocoder-like effect. This is accomplished by using frequency characteristics that visually resemble a comb with sharp teeth, so to say. Its peak frequencies are tuned according to musical tonalities and their respective overtones.

Another useful and innovative feature is the ability to load frequency response files. The custom .MEB file format is a plain text file that can be edited with any text editor. The developer has provided a set of example files with comb filter characteristics to help new users explore the plugin’s musical filtering abilities more easily.

What’s even more interesting is that you can load frequency characteristics with a MIDI controller via regular CC mapping. This way, you can actually “play” the comb filters, not unlike a real vocoder.
