Ironhead:Spawn

Ironhead:Spawn is a free drum machine VST plugin developed by Ugo. Compatible OS(s): Windows.

Ironhead:Spawn is a bundle of 13 individual polyphonic synths, built from mutated versions of the original Ironhead synthetic junk yard percussion kit instruments. They have grown, taken on lives of their own, and have been modified to be played across the keyboard like “normal” instruments. Their sound design abilities have expanded and they’ve been altered for a greater balance between percussive and melodic instruments, opening up a wide variety of sounds that are not possible with the original Ironhead, but while maintaining the unique Ironhead character and complimenting the original kit.

Kicks, snares, hats, cymbals, bells, rubbery basses, plucked strings, knocks, bonks, metallic smacks, tuned percussion, weird morphed noises… you can make entire pieces of music just using this bundle. The best way to think of the difference between Ironhead and Ironhead:Spawn is that Ironhead is a drum kit and Ironhead:Spawn is a whole band.

Features:

13 plug-ins dedicated to unique percussive and melodic sounds.

Morphing for each instrument, controlled by LFO, mod wheel, or automation.

Minimalist vector based interface for fast, fun, easy sound adjustments.

Instrument randomizers.

Adjustable level of random tonal variations per-hit.

Dual delays in each synth.

Over 40 presets in each plug (over 540 presets in the bundle).

As an added bonus, just as with Ironhead, Ironhead:Spawn also comes with Tunguska… a morphing multi effect plug-in that includes a pitch shifting granulator, filter, envelop follower, distortion, downsampling, and delays.

Iridesynth’s Revenge

Iridesynths Revenge is a free software synthesizer developed by NOVUZEIT. Available format(s): VST for Windows.

Iridesynth is a stereo virtual analog subtractive synth designed to provide “entertainingly unique tones” with fast and simple programming. It is capable of strong classic analog sounds, retro vintage video game arpeggios and other useful traditional tones as well as “futuristic unheard of sounds”.

Iridesynth features Additive Feedback Harmonics, self-modulating LFO parameters, multiple ADSRs, and seven range octave support. It also includes a powerful Global FX section with effects such as bit reduction, stereo flanging, microdelay, stereo reverb, and even psycho-modulation. There are eight configurable effects in all, each with two configurable parameters. Plus, Iridesynth’s GUI allows realtime manipulation of its interface’s color scheme.

Iridesynth’s Revenge expands upon this original concept of an all around “workhorse synth”, capable of leads, pads, and textures. It accomplishes this by incorporating many changes, including:

Dual Phase Distortion oscillators replace old Subtractive synthesis ones.

Iridesynth’s Revenge uses less than half the CPU power of the first Iridesynth.

No more key-to-note latency.

Now two forms of Arpeggiator available: Note-Arp / Glide-Arp.

Four Waveshapers enhance Phase Distortion capabilities.

Completely new Global FX section; includes Comb Filter, BitCrush, Multi-Delays and more.

Over 30 LFOs for extensive parameter automation capability.

Completely redesigned Iridescence FX section for enhanced GUI alteration ability.

Over 100 presets.

Completely rewritten very extensive user manual.

IQ4gui

IQ4gui is a free eq and compressor VST plugin developed by platinumears. Compatible OS(s): Windows.

Imagine a standard compressor with a filter inserted in the side-chain, so that it only responds to certain frequencies. Now imagine that instead of controlling the overall gain of the signal, it only controls the volume of specific frequencies… you just discovered dynamic EQ – IQ4gui.

In other words, it can compress or expand specific frequencies in a similar manner to multi-band compression (but with a very different character) or it can de-ess, or perform more esoteric functions such as ducking one frequency when another is prominent.

You may find it easier to imagine the process as an automatic EQ, which can be used to cut a certain frequency only when it becomes a problem, or apply a boost only when that region isn’t already loud enough.

While the audio signal passes through all four EQ bands in series, the side-chain filters are configured in parallel and are all fed from the main input, so changes to band one (for example) will not affect the amount of gain reduction or expansion applied by any other bands.

Features:

4 identical EQ bands, switchable between shelving or peaking types.

4 dynamics processing modes (up or down, compression or expansion).

RMS detection for musical dynamic shaping.

Separately tunable sidechain filters with side-chain listen option.

MS processing.
