Odin 2 - The WaveWarden [FREE}

Odin 2 is open-source! You can find the source code repository on the GitHub project page. Probably aimed more at the beginner wishing to learn syntheis but ODIN 2 does have some great features not found in other FREE vst's, such as the interchangeable FX section and numerous types of oscillators.Sounds pretty good and definitely worth checking out!

Look no further, Odin's got you covered! The sound of this 24-voice polyphonic beast will take you from your studio right to Valhalla. Earth shattering basses, exquisite leads or mad FX, Odin's got them all! Use the classic sound of analog waveforms - or draw your own. High quality emulations of legendary analog filters like the Moog-ladder or the Korg-35 further shape your signal. Round your sound off with four onboard FX, or get crazy with modulation. There's much to discover in Odin 2. Version 2.2.4 - fixed Legato carrying current value over to Attack rather than to current ADSR section - ChipDraw tables now available as LFO waves - XY-Pad automation can now be recorded in DAW - added background fill to chipdraw and wavedraw editors - disabled "Made with JUCE" splashscreen - fixed permissions path in mac installer script when copying file over from old soundbank location - added new patches to factory sound bank - git commit hash is now displayed in the help-section

Vital - Mat Tytell

Fantastic new spectral morphing wavetable synth with quite a unique character in the sound department and several very interesting features not found elsewhere, such asstereo spreadv on the LFO. There's more than a a dash of Serum and Arturia Pigments in the look and features. The free version has some limitations compared to the paid version, but, hey this is a real steal for being totally free.

Valhalla Delay - Valhalla

Probably one of the very best delays out there which is more than just its name suggests.

Echoes of the past, present and future
Valhalla Delay is our take on classic and modern delay and echo units. Tape echo, BBD, old-school digital, pitch shifting – we’ve got you covered. ValhallaDelay offers the classics, and expands them into new dimensions, with the unique Ratio and Quad delay styles, the Ghost mode (which adds frequency shifting), and a powerful diffusion section that can create anything from smeared echoes to ethereal reverbs. Set the controls for the heart of the sun with ValhallaDelay!

Valhalla Delay has ten different delay Modes:
Tape: Modeled after vintage tape echoes, with all the features and quirks that were loved in the old hardware.
HiFi: A higher fidelity tape echo, where the ability to precisely sculpt the sound is in your hands. .
BBD: A dark, low fidelity bucket brigade delay model.
Digital: A cleaner, higher bandwidth delay, with the ability to dial in digital dirt.
Ghost: A Valhalla DSP original! Combines the tape model from the HiFi mode with frequency shifting and a unique diffusion algorithm, for sounds that will split your skull in two.
Pitch: A digital delay with added pitch shifting. Perfect for micro-shifting vocals, adding harmonies to synths, creating vast shimmering soundscapes, or shrieking sounds that forever spiral upwards or downwards.
RevPitch: Reverse pitch shifting! Everything that goes in, comes out reversed.
BBDuck (new in 1.5.2): A brighter BBD model, with brightness that tracks the delay time (shorter delays are brighter, while longer delays are darker), and ducking.
Clarity (new in 1.5.2): A clean “digital” delay, with a program dependent limiter, so you can SLAM the drive gain without getting distortion. Deep and wild modulation waveforms, selected by the Era control. Ducking!
DuckTape (new in 1.5.2): A tape delay with built-in companding noise reduction and ducking.

Five tape Styles, for controlling the number of delay voices:
Single: Same delay length & modulation for left and right channels.
Dual: Independent delay lengths for left and right channels.
Ratio: The right channel is set to a ratio of the left channel, and the feedback of left and right channels is mixed. Perfect for sounds that slowly transition from delay to reverb-esque.
PingPong: A delay that bounces between the left and right channels, with the ability to set the left and right delays independently.
Quad: Models the multi-head tape echoes of the 1960s and 1970s, with up to 4 delay taps on tap.

Cool features:
Delay lengths ranging from 0 msec to 20 seconds. Dial in choruses and flangers, slapback echoes, longer delays, or long Frippertronic loops.
Sync the delay to the beat, with straight/dotted/triplet options. Or, control the length via milliseconds.
Age control, for adjusting the artifacts of the delay mode. Clean and shiny, old and dusty, or anywhere in between.
Powerful Diffusion section, that can be used to smooth out the attacks of delays, or can be an amazingly smooth and lush reverb in its own right. Up to 20 seconds of diffusion time possible!
Era control, for selecting between different variants of the delay modes.
Ducking control (in BBDuck/Clarity/DuckTape modes), for having the echo level track the input signal volume.

Zebra2HZ - UHE

This is the so called 'Dark Zebra' version with a bank of presets from the famous soundtrack composer 'Hans Zimmer' and others. Customized to his own taste with several new features.The new GUI is really nice indeed!

A bank of over 400 presets, a collaboration between Hans Zimmer and Howard Scarr. Practically all Zebra sounds in the The Dark Knight as well as The Dark Knight Rises soundtracks are included, plus several more that didn’t quite fit into the scores. The pack also includes Hans' custom built update from a licensed Zebra2.x to the version you can see in this video, ZebraHZ. Several of the more recent patches make use of the extra features available in ZebraHZ.

Supermassive - Valhalla

A hybrid of a Delay and Reverb in combination which can produce some really uique sounds. It's Valhalla so it's got to be good, and best of all it's entirely FREE!

ValhallaSupermassive is designed to blow your mind and your music to new levels of consciousness and experience! Luscious clouds of reverb, otherworldly delays, swelling waves of feedback unlike any you’ve heard before.

ValhallaSupermassive has been designed from the ground up for MASSIVE delays and reverbs.

Supermassive uses a variety of feedback delay networks, where each delay in the structure can be up to 2 seconds long. Combine these long delays with the unique WARP control, and the results range from echoes that slowly fade in, to cascading harmonic echoes, to lush reverbs, onwards to reverbs that decay way over the course of minutes.


Features:
• Tempo synced delays, up to 2 seconds
• Multiphase delay modulation
• DENSITY control, that allows you to dial in pointillistic echoes, lush reverbs, echo clusters, and all sorts of sounds in between.
• Eight unique delay/reverb MODES, named after celestial objects:
- • Gemini: Fast attack, shorter decay, high echo density.
- • Hydra: Fast-ish attack, shorter decay, low to high echo density (depending on the DENSITY control setting)
- • Centaurus: Medium attack, longer decay, medium to high echo density (depending on the DENSITY control setting)
- • Sagittarius: Slow attack, longer decay, high echo density
- • Great Annihilator: Medium attack, very long decay, medium to high echo density (depending on the DENSITY control setting)
- • Andromeda: Slowest attack, very long decay, very high echo density
- • Lyra: Fast attack, shorter decay, low echo density
- • Capricorn: Fast attack, shorter decay, medium echo density
• Cross-platform preset browser
