A delay effect that features pre- and post-effect filters. Each of the three delays can have its own dedicated filters, enabling you to create everything from subtle spatial effects to twisted glitch sounds.

Prysm Audio Monosc

Platform/format: PC/VST Download

The brainboxes among you will probably be able to deduce from the name that this is a single oscillator monophonic synth. It has a Unison mode (1 to 16 voices), a filter that offers four different types and - from the look of it - a very simple interface.

Xenobioz Kruudster

Platform/format: PC/VST Download

A hybrid synth plugin that sports three oscillators, three LFOs, a Randomizer key, three ADSRs, a filter and more. Kruudster is said to be notable for its drawable low resolution waveforms.

Juno Ju-X Gimmick Graph

Platform/format: Mac/AU Download

Appropriately enough, given its name, Gimmick Graph promises a new synthesis method. Its oscillator hits upon its waveform by setting how many times to twist it in a cycle, dividing it up by scanning up and down, before finally allowing the player to determine the positions of the turning points. There's a graph on the website to explain the process, but you might be better off just giving the thing a try.

Klanghelm IVGI

Platform/format: PC/VST Download

Put some "soft and subtle" saturation on your master buss or add "dense and dirty" distortion effects to individual tracks with this simple looking plugin. IVGI is said to react dynamically to the input signal and to deliver a lively, real and transparent sound.

Platform/format: PC/VST, Download

A subtractive synthesis-based drum and percussion instrument.

There are four stereo outputs, each of which has its own effects section.

SonicXTC Deep-Mono

Platform/format: PC/VST Download

Designed in the spirit of the classic '70s monosynths, this single-oscillator instrument promises to be easy to program - all of its parameters are displayed on the front panel. There are 70 presets, but the real fun may come in creating your own.

Saltline Drzewo Liść-verb

Platform/format: PC/VST Download

Two freebies in one bundle. HUE-X is an EQ that's designed for people who like to experiment with sound, giving you ten descriptively named faders to tweak.

This ad-supported instrument is based on additive synthesis technology and comes with four waveform types and 32 harmonics that can be drawn with your mouse. You can also adjust the attack, decay, sustain and release for each harmonic, while a low-pass/high-pass filter, an LFO and chorus can be called into play, too.

TA Programming SubSonic

Platform/format: PC/VST Download

Billed as "the synth that takes you back," SubSonic is a subtractive instrument that promises to give you a vintage sound. Among its tools are three oscillators, a graphical ADSR envelope, a multimode filter and reverb, delay, chorus, flanger and warper modules.

Sleepy-Time DSP Lisp

Platform/format: PC/VST Download

This level-independent sibilance processor is said to be a new type of de-esser that offers automatic sibilance detection. It does this by tracking the amplitude and pitch of its input in real time - set the reduction amount and Lisp will work on eliminating those unwanted 'ss', 'the', and 'ch' sounds.

Saltline Drzewo Liść-step

Platform/format: PC/VST Download

A simple state-variable filter (low-pass, high-pass, band-pass, band reject) that enables you to control the cutoff frequency via either the 16-step sequencer or the LFO. Modulated filter patterns are easy to create, so we're told.

TDR Feedback Compressor II

Platform/format: PC, Mac/VST, AU Download

Designed specifically for bus compression but suitable for mixing tasks as well, this plugin analyses the output signal and promises highly musical compression and the ability to handle complex signals with ease. Rather than attempting to emulate any classic hardware, it's proudly digital.

Nick Crow Lab Wagner Sharp

Platform/format: PC, Mac/VST, AU Download

This tube guitar preamp emulation certainly looks like a real piece of hardware, and it may well sound like one, too. There are two channels and a stereo mode to handle double tracking, with each channel only being activated when a signal is present in order to preserve CPU power.

Qirex Audio Qirex Player 2.0

Platform/format: PC/VST Download

TSE Audio TSE X50

Platform/format: PC/VST Download

TSE's latest emulation is of a famous US guitar amp that's been used on a lot of metal records. There were actually two very similar versions of said amp, so you get two separate channels. If you like the plug-in, consider giving the developer a donation.

Xen-Arts XenFont

Platform/format: PC/VST Download

A two-oscillator SF2 SoundFont/subtractive synthesis instrument that features full controller MIDI Pitch Microtuning, meaning that you can use it to experiment with alternative intonation systems. Load in your samples and put them through the synth engine to create new timbres.

Plogue sforzando

Platform/format: PC, Mac/AU, VST Download

This lean-looking SFZ 2.0 sample player has just one instrument slot, no fancy interface and no effects or mixer. What it can do, though, is play back files in this royalty-free format, while SF2, DLS and Acidized WAV files that are dropped in will be converted to it.

Solcito Musica BabyTron

Platform/format: PC/VST Download

Just missing the deadline for the KVR Developer Challenge 2012, this analogue-style and phase distortion virtual synth is a cutdown version of Solcito Musica's SuperTron. It gives you just one oscillator, one envelope and one filter to work with, and the interface hides knobs that aren't currently needed.

Extent of the Jam Digits 1.3

Platform/format: PC, Mac/VST Download

A significant update to this phase distortion synth that adds a full editor GUI and has much lower CPU usage. The synth was inspired by Casio's CZ series and can produce pads, glitchy sounds, basses, sweeps, leads and more. A Linux version is now available, too.

Tokyo Dawn Labs TDR Feedback Compressor

Platform/format: PC/VST Download

It seems that there are now almost as many free compressors out there as there are chargeable ones, this one being the latest example. This is an RMS-based dynamic range compressor that's designed for summing/bus use and, refreshingly, it's "proudly digital" rather than any kind of analogue emulation.

Syncersoft Analog Warp

Platform/format: PC/VST Download

A warping and morphing effect that's "designed to deliver the clear, penetrating sounds favoured by live musicians". It's said to have uses for producers who work in all manner of different genres, though the LFO section was put in with dubstep folk very much in mind.

Another effects-chain-in-one-plug-in from SonicXTC. This one comes with a chorus that can be used to help background tones to sit better in a mix, a flanger to give harmonically rich sounds more presence, and an envelope follower to provide more tonal interest and movement.

Distorque Vitamin C

SonicXTC Filta Crunch

Platform/format: PC/VST Download

Filta Crunch recreates the popular studio insert effects chain of filter (a Moog-style one, in this case), tube amp and waveshaper.

The waveshaper, meanwhile, promises to give the plug-in an extra dimension.

ToneBytes Lo-Fizer

Platform/format: PC/VST Download

Platform/format: PC/VST Download

A couple of freebies that are designed to help you to create monosynth basslines. Fratzoor is an analogue-style step sequencer that comes with randomizers for pitch, velocity and trigger. Distel was originally created as the test synth for Fratzoor, but the developer believes that it turned out well enough to be released.

SonicXTC Liquid Verb

Platform/format: PC/VST Download

A stereo delay plug-in that has two separate delay lines for left and right. You can adjust parameters for these separately, and you'll also find a couple of LFOs. There are 16 patches to show off what the effect can do.

Wok Superfake

Platform/format: PC/VST Download

This effect promises to make any saw wave sound like Roland's classic Supersaw. It does this by way of its six detuned voices, which can be spread across the stereo field. The amount of detuning can be adjusted. Although Superfake is free, you can pay €9 to remove the nagscreen that pops up when you open it.

Ignite Amps SHB-1

Platform/format: PC, Mac/VST, AU Download

Although the SHB-1 is a software recreation of the hardware bass amp of the same name, it was actually built before the 'real' model so that the player who commissioned it - Federico Fulceri - could take it for a test drive. It's billed as an "Extreme Bass Head" so expect plenty of grunt.

Tok-Tok Neuser

Platform/format: PC/VST Download

An experimental synth that was created with SynthMakerCM, the version of SynthMaker that's supplied on our sister magazine Computer Music's cover disc. Waveforms can be drawn onto the oscillator and you can create a filter-modulated sound with a few clicks and knob turns.

Platform/format: PC/VST Download

Variety Of Sound Density mkIII

Platform/format: PC/VST Download

Already nominated in our poll to find the best free VST plug-ins in the world today, this compressor has had some "deep optimisations" made to its engine which should be particularly useful in mastering situations.

Vladg/Sound Limiter No6

Platform/format: PC/VST Download

A modular limiter that's designed for mastering. There are five modules: an RMS compressor, a peak limiter, a high-frequency limiter, a clipper, and a true peak limiter. The plug-in can do both brickwall and soft limiting and sports M/S and multiband modes.

RobotPlanet BattleComp Vintage

Platform/format: PC/VST Download

There's no proper interface for this one (so its look will depend on the host you're using) but BattleComp Vintage is said to be a smooth compressor with an EQ and a high-pass filter on its internal sidechain, plus a soft clipping circuit at the output stage to control peaks.

Wok Bassimo

Platform/format: PC/VST Download

DDMF ColourEQ

Platform/format: PC, Mac/VST, AU Download

Not just another EQ, we're told, but one that sounds unlike any other. The five bands of super-parametric peaking filters are responsible for this uniqueness, apparently - you have one more parameter on top of the standard gain/width/frequency to influence the curve shape.

Syncersoft Bass Landscapes

Platform/format: PC, Mac/VST, AU Download

Previously featured in one of our paid plug-in round-ups, this bass boosting plug-in can now be yours for nothing. You can use the low-mid boost to help sit your bass or kickdrum in the mix and turn on tube emulation for a vintage feel.

Syncersoft Analog Voice

Platform/format: PC/VST Download

A subtractive synth that promises extended modulation possibilities. There are four types of analogue-style filter onboard, plus delay and reverb effects and a tempo-syncable LFO. The detune effect, meanwhile, can add strangeness and fatness.

Mothman Z3000 and 2000

Platform/format: PC/VST Download

The developer admits that he won't have time to update these two synths any time soon, so has decided to set them free. The Mothman Z3000 is a 16-voice polyphonic instrument while the 2000 is a 2-oscillator subtractive beastie.

Syncersoft Lizard Morph

Platform/format: PC/VST Download

A detune and morph effect that's said to be particularly useful to anyone who's looking to produce the powerful, penetrating sounds that are associated with a lot of contemporary dance music. The LFO section, meanwhile, has been included with dubstep producers particularly in mind.

LSR Audio LVLMeter

Platform/format: PC, Mac/VST, AU Download

A vintage-inspired stereo peak level meter that comes in 32-bit and 64-bit varieties. That's all there is to say, really; the only other things you'll find in the way of a 'feature' are markers to indicate peaks.

Syncersoft Q9 Oldvox

Platform/format: PC/VST Download

Yet another Syncersoft release, Q9 Oldvox is an analogue-style synth that's said to deliver a sound that's warm and fat. The two oscillators are complemented by filters, LFOs and a delay effect.

Fsynthz PhybAce Pilot

Platform/format: PC/VST Download

A physically modelled bass guitar that emulates the string, pick, body resonances and pickups. There's a slide mode, too, for legato playing.

Syncersoft Saw Landscapes

Platform/format: PC/VST Download

Based on the Bass Landscapes plug-in we covered a few months back, Saw Landscapes is a synth that can be used to create both musical sounds and FX. It has a stompbox-style interface that should appeal to those who want to keep their controls simple.

Bass Gnomes Clarity and Full Phase

Platform/format: PC/VST Download

A couple of phase-related effects: Clarity uses phase shifting and comb filtering to enhance the clarity of your audio signal; and its little brother Full Phase allows phase tuning via a process that involves inverting a stereo channel "phased against the opposite corresponding channel to isolate common stereo field characteristics".

Xenakios HourGlass

When trying to picture this new synth, the developer suggests that you "Imagine rummaging through an abandoned factory and finding this rusted box.

Madrona has pulled the reverb unit out of its Aalto synth, packaged it up in an Audio Units plug-in and then served it up as a free download. It's not exactly a complex device, having just dry/wet mix and brightness controls, but that'll make it easy to use, and CPU efficiency is also promised.

NTS Audio Labs Benassi Bass

Platform/format: PC/VST Download

This might just be the first free synth to be based on (and named after) the sound of a specific artist: its sole purpose appears to be to give you the Benny Benassi bass sound. To this end, there are two sine/saw oscillators, a double saw oscillator, a resonant filter, reverb and a glide option. What's more, 32 presets are included.

Prodyon Phenome

Platform/format: PC/VST Download

An 8-layer/8-part multitimbral SoundFont player that gives you typical synth-like features such as filters, an ADSR envelope and arpeggiators. You can make individual settings for each layer (MIDI channel, volume, pan, mute etc) and there's full MIDI Learn functionality.

Tekky Synths VoCoGaTe Free

Platform/format: PC/VST Download

It may have been originally designed to process vocal samples with its pitch shifting and gating abilities, but Tekky Synths says that VoCoGaTe's purpose now is to help you create "infinite percussion variations". This free version (the full one costs €30) has no main detuner, no FX and only one active patch but is properly functional.

DSK Overture

Platform/format: PC/VST Download

DSK is attempting to put an orchestra in your DAW with this one: there are 40 symphonic instruments and a drum kit. The plug-in has a four-layer architecture; layers can be stacked or sent to different MIDI channels. A range of sound-shaping options is available to each layer.

GTG Synths NR2010

Platform/format: PC/VST Download

The developer says that this, his "personal workhorse synth," was built for personal use but is now being made available to everybody. It's an analogue-style polysynth with a 24dB filter, envelopes and modulation effects.

Necromare Music Polyslop

Platform/format: PC/VST Download

This is Necromare's first instrument - full marks for choosing such an excellent name for it. It's a simple synth that's designed to emulate vintage Arp/Moog sounds, though the developer isn't making any great claims for it, saying that it was made "as more of a test than anything else".

A.O.M. Invisible Limiter

Platform/format: PC/VST Download

A simple proposition, this: The Invisible Limiter is a transparent look-ahead brickwall limiter with automatic attack/release time optimisation. It's said that the plug-in's limiting algorithm minimises the difference between the original and limited materials.

Mildon Studio Optobongo

Platform/format: PC/VST Download

If you're lacking a go-to bongo plug-in, here's a free option that varies the location and intensity of the hit each time you trigger it. It's based on "an authentic cowhide bongo made in the mountain province of Benguet, Philippines," apparently, with the developer also saying that "if you're making the soundtrack for the next Pocahontas sequel, maybe this can come in handy".

DSK Music DSK SF2

Platform/format: PC/VST Download

The SoundFont format remains surprisingly popular, so much so that DSK has considered it worthwhile upgrading its SoundFont player to version 2. This adds a portamento time control, filter amp envelope, delay and a "redistributed GUI".

Sir Elliot Five-Band Graphic Equaliser

Platform/format: PC/VST Download

This simple graphic EQ was inspired by Sir Elliot's old BSR equaliser - having fewer bands reduces the chance of having an overly processed mix, he reckons. It's designed for mixing and mastering. You can see and hear if for yourself if you watch this video.

Loop&Sound Eternity

Platform/format: PC/VST Download

Each of this synth's two oscillators can draw on a library of around 140 waveforms and operate in Single/Dual/Fat/Ultrafat modes. There's also the 'custom randomisation' feature to tell you about, which can be assigned to any knob and promises to aid the speedy generation of new sounds. You'll have to register on the website to download this one.

Wok dTUNE

Platform/format: PC/VST Download

dTUNE works by adding a pair of detuned voices to the audio signal that you feed it, thus fattening it up. Simply set the amount of detuning, stereo spread and mix level and away you go. The full version costs €9, but if you can live with a nag screen and without the option to save presets, you can have dTUNE for free.

acid.milch&honig Stylobox

Platform/format: PC/VST Download

One look at the GUI for this one should be enough to let you know which buzzy, portable instrument it emulates. Let's put it this way: if Rolf Harris has a DAW, he'll probably be interested. Stylobox is donationware, so put something in the pot if you're going to use it.

acid.milch&honig Transistor Drums 2.0

Platform/format: PC/VST Download

The second version of this vintage-style drum machine makes some changes to the way the drum sounds are generated. The kick is virtual analogue rather than sampled; the snare an analogue/sample mix rather than being just sampled; and the clap granular sampled rather than just sampled. Again, Transistor Drums 2.0 is donationware.

Audiocation AC1 Compressor

Platform/format: PC/VST Download

Yet another compressor, this one makes the not unusual claim to be low on CPU usage but high on sound quality. Choose your ratio, make tweaks using the Attack, Release, Threshold, Softknee and Output Gain controls, and check signal levels in the analogue-style meter.

H G Fortune Alphatron Basic

Platform/format: PC/VST Download

Even the developer admits that this is "just a simple VA synthesizer", but its trick is that the third oscillator uses digital waves. This means that you can produce tones other than typical analogue ones, and there's also a step sequencer. This free version has some limitations - upgrade to the Pro edition for €29 to see them removed.

Fsynth Clavidium

Platform/format: PC/VST Download

This additive synth certainly isn't a looker but its developer reckons that it offers "great sound" and low CPU consumption. What's more, the distortion is described as state-of-the-art. Originally designed for producing harpsichord and Clavinet sounds, its potential sound palette actually promises to be rather more wide-ranging.

Melda Production MFreqShifter

Platform/format: PC, Mac/VST, AU Download

"An extremely versatile frequency shifter which, unlike pitch-shifters, doesn't keep harmonic relationships and can provide everything from mild stereo expansion to complete destruction." That's what Melda Production has to say about MFreqShifter, and if you want to upgrade to the Pro version, you can do so for €30.

Hello Robot Rocket Punch and Bit Box

Platform/format: PC/VST Download

Hello Robot are actually a band that likes "video game music, lo-fi, 8-bit, glitch and noise". The two plug-ins they've developed fit their personality: Rocket Punch is a synth with adjustable bit-rate, while Bit Box is an 8-bit drum sampler that comes with over 500 video game chip sounds.

Mildon Studios Vocal Spread

Platform/format: PC/VST Download

Simplicity is the watchword here: this plug-in is designed to enhance your vocals' stereo spread, making them cut through the mix and sound wider. It can work on instrumental parts, too, and tweaks are made using Body and Spread controls.

DSK Music DSK Guitars

Platform/format: PC/VST Download

The name says it all really: three separate plug-ins that emulate acoustic, steel and nylon guitars. A very similar GUI is used on each of them, and keeps things simple by presenting you with just ADSR and level controls.

DSK Music TechSynth

Platform/format: PC/VST Download

DSK has been busy, for as well as releasing those three virtual guitars, it's given us this two oscillator synth. Each of these can choose from five waveforms, and you've also got a filter, amp envelope and delay effect. 60 presets are included, so there are plenty of sonic starting points.

SyS Audioresearch n0t0mizor

Platform/format: PC/VST Download

n0t0mizor gives you a simple way of generating randomised MIDI notes, though you can define certain parameters yourself. It doesn't affect any MIDI information other than pitch, and its output can either be used inside your DAW or sent to an external instrument.

Tactile Sounds TS-Substance

Platform/format: PC/VST Download

If you were asked to come up with a list of things that you'd like to see in a new free soft synth, simplicity, flexibility and (good) sound quality would probably be on it. This is what Substance promises: it was inspired by the classic analogue polysynths of the past and has two oscillator sections, two LFOs, two envelopes and two filters.

AuraPlug Freetortion Series

Platform/format: PC, Mac/VST, AU Download

OK, it's not new, but Mac users should be aware that Auraplug's Freetortion Series, which contains six guitarist-friendly amp/FX plug-ins, has just been ported to OS X. The only stipulation is that you'll need an Intel-based machine to run them.

Togu Audio Line TAL-NoiseMaker

Platform/format: PC, Mac/VST, AU Download

We previewed this one last week, and now it's available. It's an improved version of the already excellent TAL-Elek7ro, but comes with a new synth engine and an effects section with reverb, chorus and a bit crusher. Could this make a late push for the title of best free VST plug-in in the world today?

Wok Dronos

Platform/format: PC/VST Download

A virtual analogue synth that specialises in creating drones might not seem too appealing, but Wok says that Dronos is capable of producing "a warm, ever-evolving sound which remains tonally playable". The free version is monophonic and has a nag-screen.

Boomplug BoomComb

Platform/format: PC/VST Download

Seemingly Boomplug's first plug-in, this is a MIDI-controllable comb filter. The delay time is in Hz, and can be set by pressing MIDI keys or 'bent' using the pitch wheel, which effectively means that it can be played like an instrument. There are GUI and non-GUI versions available: you'll have to use the latter if you're running Windows XP.

Plektron WTComp

Platform/format: PC/VST Download

Fancy some free analogue tube-style compression? That's what WT Comp promises, and Plektron has kept things simple on the interface. Although it says that "the internal structure is very advanced," all you have to do in terms of tweaking is adjust the Warm (compression) level to taste.

Togu Audio Line NoiseMaker

Platform/format: TBC, Info

Togu Audio Line is one of our favourite freeware developers, so we thought we'd like to know that it has a new synth on the way that goes by the name of NoiseMaker. There are no specs yet, but you can hear and (sort of) see it in action in this strange preview video.

Sir Elliot Brass Instrument Equaliser

Platform/format: PC/VST Download

It's rare to find an EQ that's so explicitly designed for use on one group of instruments, but yes, this one really is said to be made for use "solely" on trombone, saxophone, trumpet and other brass parts. If you want to hear it in action, check out the videos here and here.

DUY Z-Room

Platform/format: PC, Mac/VST, AU, RTAS, MAS Download

Previously charged-for (we think), this cross-platform reverb plug-in can now be yours for nothing. The developer believes that "high quality density and diffusion provide unparalleled sound quality," and there are 50 presets. You'll have to fill in a registration form to get the download, but that's the only price to pay. Note that the PC version is RTAS only.

WOK Simprev

Platform/format: PC/VST Download

The latest freebie to be cooked up by WOK (do you see what we've done there?) is a simple reverb plug-in. And we really do mean simple: just Time, Damp and Mix controls are included, along with a chunky Bypass button. You'll be nagged for a donation until you make one, but Simprev is fully functional.

J1000 plug-ins

Platform/format: PC/VST Download

There are four EQs in this new range from J1000: Alpha (for post production); Beta (for mixing); Gamma (for mastering); and Delta (a mixing EQ "with a twist"). Developer Jovan Iljadica says of his plug-ins: "They are just regular equalizers made according to my ideas of how should they look and react".

Minimal System Contakt

Platform/format: PC/VST Download

There are two oscillators in this synth, each of which can choose from five waveforms. The oscillators can be mixed, while there are also delay, filter and reverb modules and a built-in oscilloscope.

WOK Simpshi

Platform/format: PC/VST Download

WOK has also served up (you see what we've done there again?) this pitch shifting effect, which is designed "mainly for non-percussive material". Before you get too excited, though, bear in mind that the developer says: "it is the result of some testing and experimenting, so don't expect high quality results". Well, at least he's honest.

Sir Elliot Little Black Box and LRC-II

Platform/format: PC/VST Download

A couple of compressors from this knight of the free software realm. Little Black Box is a low dynamics offering that's said to be appropriate for rock music production, while LRC-II promises to be suitable for use on jazz and dance material.

Homegrown Sounds Harmonic Enhancer

Platform/format: PC/VST Download

Built by the developer for personal use but now available to all of us, Harmonic Exciter enables you to add harmonic distortion at around 10k and 100hz. The idea is that you can use it to brighten up dull audio, particularly the top end.

Martinic Combo Model V

Platform/format: PC, Mac/VST, AU Download

OK, it's not strictly a new plug-in, but it's been a bit of a PC-fest over the past few weeks (OK, a lot of a PC-fest) so Mac users will be pleased to learn that the Combo Model V organ is now OS X-compatible too.

Full Bucket Music Mono/Fury

Platform/format: PC/VST Download

Korg's Mono/Poly was a big hit among synth heads in the early '80s, and that's the instrument that inspired the creation of this one. It promises to offer "close emulation of behaviour and all controls," and the developer also reckons that it's light on CPU usage.

eaReckon FREE87 series

Platform/format: PC/VST Download

Not just a new free plug-in, but a new series of free plug-ins. The FREE87 range currently contains a compressor with integrated brickwall limiter, a gate, a 1-band parametric EQ and a brickwall limiter, and all have very simple interfaces.

Platform/format: PC/VST Download

This plug-in, which was originally created for KVR's Developer Challenge 2009, enables you to use your video game guitar controller (one that's DirectInput compatible) as a MIDI controller for your DAW. This update fixes various issues and adds a couple of new features.

Lday Athmonova2

Platform/format: PC/VST Download

Yet another virtual analogue synth for the pile: this one gives you an oscillator, filter, LFO, three envelopes and overdrive/distortion, delay and stereo widening effects. As such, it doesn't really do much more than a hundred other synths, but give it a try and see how it fits.

Martinic Combo Model V

Platform/format: PC/VST Download

Drawbar organ emulations seem to be disproportionately common in the land of free plug-ins - this latest offering is modelled on a "well-known combo organ from the '60s". As well as the organ emulation, there's also a vibrato unit with adjustable speed and depth.

Martin Eastwood Audio Mverb

Platform/format: PC, Mac/VST, AU Download

This open-source reverb is based on "the figure-of-eight reverb structure suggested by Dattarro, which uses a bank of all-pass filters to smear the phase followed by a loop of multi tap delay lines that feedback into themselves to create echoes". Eastwood has also added another delay and a multitap delay to act as predelay and early reflections.

Pluggotic Squosc and Footile

Platform/format: PC/VST Download

A couple of quirky effects plug-ins from Pluggotic with suitably offbeat names. Squosc is a seemingly unpredictable compositional aid that features constantly running oscillators that are modulated by an envelope follower, while Footile is based on a serial multi-FX design. The plug-ins come with presets that are described as "horrible" and "unsuccessful" respectively.

g200kg RoVee

Platform/format: PC/VST Download

This cutdown version of g200kg's KeroVee (which has just been updated) is a basic voice-changing plug-in. It enables you to make a male voice sound female and vice versa. You can also add a robotic-style effect into the mix.

Pianovintage 1984

Platform/format: PC/VST Download

A traditional-looking synth that gives you a pair of oscillators and filter and envelope sections. There are chorus and delay effects, too. You might be put off by the fact that only eight presets are supplied, but this is a simple looking instrument so programming your own shouldn't be too difficult.

Saltine Hotel S.O.A.P

Platform/format: PC/VST Download

Designed with the forthcoming FreePlayer guitar effects controller in mind, this pitch bending effect (the acronym stands for Son Of A Pitch) is said to be suitable for use as a virtual whammy bar and for more extreme pitch bend tasks. The dead zone control enables you to adjust the pitch response to suit your playing style.

Tekky Synths THriCe

Platform/format: PC/VST Download

Although the full version of THriCe costs €30, there's also a free iteration that has most of its features (only filter modulation by the 3 StepSeq LFOs is missing). What we're dealing with here is a 3-oscillator synth, with each oscillator having its own multiband filter. There's also an internal sequencer and an FX section.

Tactile Sounds TS-808

Platform/format: PC/VST Download

TS-808 is - wait for it - an emulation of the Roland TR-808 drum machine (you got the subtle hint didn't you?). As you probably know, it isn't the first, but Tactile Sounds points out that this is a proper synth rather than a sampler, and that you have more sound-shaping controls than on the original hardware. You've got eight outputs to play with, too.

Now at version 3.5, Cerebrum is a groovebox-style drum machine that comes equipped with five drum synth modules, 150 drum sounds and a bassline synth. Each module has two 16-step pattern sequencers. The intention is that the software will be used in a live situation to create beats on the fly. The freeware version is the same as the full one except for the fact that multiple outputs are disabled.

ViSynth is another of those 'inspired by but not a copy of' virtual instruments – it's a monophonic synth based on MFB's Synth Lite. There are a couple of oscillators and a sub oscillator: we trust the sound is appropriately vintage.

Your DAW probably has its own built-in MIDI editor, but that hasn't stopped AZ Audio from releasing this plug-in version. It's also a pattern sequencer – you can use up to 64 patterns of variable lengths.

NoiseSoft Hard Line Industrial Distortion

Platform/format: PC/VST Download

Lots of developers claim that their plug-ins are easy to use, but few processors can be quite so simple as this distortion unit. It features just one knob: dial it fully to the left and the effect is bypassed; turn it fully to the right and you've got extreme distortion on a white noise level.

LePou HyBrit Series

The name alludes to the fact that these guitar amp plug-ins are based on not one British model but two (we're not told which). You get preamp, head and FullStack versions for maximum flexibility.
