Mr Ray 73

Although it may sound like a sampled instrument, MrRay SeventyThree is still synthesized, as the sound it produces is 100% calculated in real time. What characterizes this version of MrRay is a series of “imperfections” introduced in order to capture, with the highest possible fidelity, the sound of a Mark I. There are mallet noises, wooden noises, metallic artifacts and changes of volume for each single note.

Groove Analogizer is an “audio controlled drum synthesizer”, it means that like a vintage electronic drum tone generator (e.g. Simmons) the percussion sound is triggered by an audio input, not by a MIDI message. This also means that you must not load, in the host, Groove Analogizer as a VST instrument, it loads as a VST effect, usually in an insert slot. Download

even at the oscillator section only. In addtion the 2 inbuilt filters provide further means for tweaking.
Finally at the output section there is Spook fx and two delays in series incl. pan modulation for
delay and direct out for stunning spatial movement in stereo.

Dallas Hodgson / Open Ambience Project has announced the release of SHEPPi(Stereo Haas Effect Ping Pong Inverter), a stereo image enhancement tool modeled after the K-Stereo Ambience Processor by Algorithmix.

SHEPPi imparts a subtle, natural sense of space thanks to a combination of EQ'able synthetic early reflections, M-S widening and inverted stereo delay feedback.

This plug-in has been enhanced for both track insert as well as aux send applications, making it an excellent tool for both mastering and stereoizing purposes.


HARD LINE - Industrial Distortion - FREE VST

Our first effect plug in, (and it's FREE!) Custom noise based distortion effect ( VST ) will take your sound from a clean 'natural' gain to an extreme level of distortion that simulates a white noise waveform at it's highest setting.
See the demonstration videos here and here!

Single knob design:
- GAIN: Lowest setting is pure bypass, highest setting is extreme distortion, almost to the point of white noise.

The A-150 is a new and very improved version of our older amp, the A-110. Intended to enrich your sounds by blending both dry and wet signals, the A-150 includes a dry channel as well as a tube-simulated channel with a compressor, 9-Band EQ & five-mode filter (three different lowpass settings, highpass and bandpass). Designed for everything from drums to guitar, bass, monosynths and electric organs / piano, the A-150 serves as an aggressive, versatile amplifier.  Download
Blister is designed to be used only when all other attempts at making something sound horrible have failed. By combining tube-style gain, bit crushing and a synthesizer that detects your signal frequency, Blister barfs out a stew of noisy, atonal junk along with a variable amount of your original signal Download
Abyss is a very simple synthesizer effect intended to be inserted on your bass drum channel. While allowing the original signal to come through untouched, it adds a secondary layer of tunable, low end bass synth. This is a very easy way to add controlled low end to your bass drum without obliterating it with an equalizer Download
Designed with electric pianos, strings and pads in mind, Equivibe is a hybrid of an EQ and a vibrato effect. After splitting your input into 9 bands, those relative frequencies are then individually modulated by their own dedicated oscillator -- which is, in turn, modulated by an additional oscillator Download
The A-110 is a tube amp simulator with a built in 3 band EQ, compressor, lowpass filter, secondary tube channel with 4 amp models, dry output, etc. Although it was designed with drums in mind, the A-110 is a great tool for giving pianos, synthesizers and guitars a sometimes much-needed "umph" that can result in a more gritty, interesting sound Download
Four effects units -- a re-texturizer that adds 'crazy stuff' to your sounds, a stereo consolidator, a stereo separator and a destruction effect that combines several methods of disortion Download
The B-400 is a simple, yet robust synthesizer that provides a myriad of minor tonal variations to a core sound that falls somewhere in between an electronic piano and a basic poly- synth. This VST utilizes three oscillators (with 32 waveforms each) as well as a leslie / vibrato style flutter engine output as well as two other main output channels; one being a simple clean out, and the other a tube simulator with a 3-Band EQ. Each oscillator is able to be coarse tuned. Special thanks goes to Etric Van Mayer for his excellent Oscil8R SE oscillator module Download
Mindrot is an experimental synthesizer that primarily creates its sound by modulating an envelope generator. After that things start to get hazy: 14 faders, 13 buttons and 4 knobs of pure, unlabeled, modulation chaos Download
Based around Etric Van Mayer's LifeForce Sequencer, this auto-synth allows you to create, load, save and run patterns designed within the rules of John Conway's Game Of Life. The output is fed into three robust operators and then strung through a handful of effects (distortion, bit crushing, modulation, feedback modulation, etc.). The result is a pattern-based, rhythmic droning synthesizer with immense possibilities for tone variation Download
Both unique synthesizers with very different methods and purposes. Melodikon is an experimental synth derived from ideas that went into Oceans (found below), producing gobs of melodic and sometimes crusty goodness. IceClimber is more geared towards live performances. Designed around the idea of a 16 step sequencer, each 'step' in IceClimber contains a full synthesizer channel strip with all kinds of controllers for you to modify as it plays (including pitch input, looping resets, sequencer freezing, bit crushing, etc.) Download
Two synthesizers. Oceans is an experiment in filter modulation that produces an airy, flute-like, haunting sound. The other, Atlas 1, is a three operator beast of a synth. With feedback loops and atypical modulation methods, the result is a mutant FM synthesizer that finds itself at home within droning, lush soundscapes Download
Fully customizable, analog modeling drum machine (no samples!). Each sound is tunable, opening the doors for drastically different drum kit presets. The amplifier stage contains a tube simulator with pre and post gain as well as a clean output. Download
Three synthesizers (two mono, one poly) based upon various cross-modulations and feedback paths. While they are definitely up to the task when it comes to barfing out obnoxiousness and noise, they're also able to create plenty of pleasant sounds that add fresh texture to otherwise basic synth tone Download
