The Ensembletron String Synth

Planet Botch’s new Ensembletron VSTi serves only one purpose, but it serves that purpose extremely well, in an eminently user-friendly manner. This is a virtual analogue string machine inspired by classic 1970s beasts such as the Solina and Roland string synths. However, the Ensembletron is by no means a copy.

Apart from offering a high quality yet gritty and slightly rough string sound with a great balance of fidelity and warmth, the Ensembletron features a unique three-stage Ensemble section which animates and adds stereo spatial spread to the output. As you might expect, there are adjustments for slow attack, decay and sustain, but there’s also an advanced yet simple-to-use Tone Management system which can significantly change the character of the sound from vintage to modern.

u-he protoverb

Protoverb is an experimental reverb based on the idea of a "room simulator". Most algorithmic reverbs try to avoid resonances or model the reflections of sound from a rooms walls. Protoverb does the opposite. It builds up as many room resonances as possible, modeling the body of air in the room. It therefore does not need to modulate or colour the signal. The result is a very natural sounding reverbration with some interesting features: Long standing frequencies resonate louder, as if the air takes some time to get excited. Multiple instruments don't mash into a diffuse mud, they stay distinct. If you play a short melody, the room seems to repeat a ghost echo of that melody. Those properties are indeed found in churches and large halls, but they're rarely found in conventional algorithmic reverbs.

Grace sampler

Grace makes up for it with a brilliant workflow and easy access to all of the plugin’s parameters. Building a new sample library from scratch is an incredibly simple task with this plugin.
In addition to the standard sample editing controls, Grace also features a highly flexible modulation section which can help you transform static samples into exciting and lively sounds. It also comes with a nice sounding set of multi-mode filters, a pair of step sequencers and several XY pads which are very helpful in live performance situations.
Following a similar workflow ethic as the one we’ve seen in One Small Clue’s amazing Poise drum sampler, every possible action can be achieved in no more than just a couple of clicks. Building an entirely new preset from scratch (with modulations and everything else) is most often done in a matter of minutes. Compared to various more powerful (and quite often needlessly over-bloated) sampler instruments on the market, Grace is an absolute joy to use.

Rhythm Labs Twin Delay

Twin Delay is a VST plugin designed for emulation of digital and analogue delay effects. The program is not an exact copy of already existing hardware-based equipment, nevertheless it can be used for producing a majority of popular effects, as well as some modulation and 'unusual' effects, for instance Flanger, Metallizer. Special attention have been given to analogue delay algorithms, that make it possible to create beautiful and original sounds, frequently used in such genres as IDM, Experimental, Breaks and especially Dub, as well as genres that use Dub elements: Dub techno, Dubstep, Dubwise and so on.

Rythm Labs Mo-Verb

Mo' Verb is a reverberator, based on original algorithms, combining simulation of spring and digital reverbs. In our plug-in we did our best to provide basis for creating of wide spectrum of timbres, make smooth and warm sound, handy and intuitive interface for making the required sound easy and fast. While making our reverb algorithm we used specially created program for the search of inner parameters to make the sound of the reverb smooth and clear.

TDR Nova

NOVA is a parallel dynamic equalizer. Appearing in the familiar layout of a parametric equalizer, each band also includes a full featured dynamics section allowing the processor to cover an impressively wide range of applications. Be it a master lacking density, the drum bus asking for more crispiness, or a sibilance problem in your perfect take: NOVA has an elegant answer.

A user friendly WYSIWYG drag and drop display paired with a classic “knob” interface gives quick and smooth access to the various parameters driving NOVA’s powerful processing capabilities. With its four dynamic EQ bands and additional high-pass and low-pass filter sections, NOVA can meet the most exotic demand. Intuitive equal loudness functions help finding the optimal setting without getting distracted by loudness differences.

In practice, the processor covers a whole bucket of tasks:

Parametric equalization
Dynamic equalization
Frequency selective compression/expansion
Multi-band compression/expansion
Wideband compression

Noisebud Midsider

Midsider will help those who work with Reaper to add mid/side capabilities to any plugin with a minimum of setup. Check the tutorial video, you’ll be mid/side’ing in no time.

If you use Midsider for creative effects, remember that anything added to just the side signal will be lost in mono. Use our plugin Leaky or use other methods to add some of your effect to the mid channel as well.

Sanford rev + delay

Sanford Reverb was originally priced at $25 when it was first released back in March 2009. The plugin was updated to v2.0 in July that same year, with the price increased to $35 for the full version. The brand new v2.1 iteration of Sanford Reverb is completely free to download from the developer’s website and also compatible with 64-bit systems. This is the third Sanford Sound Design product that was re-released as freeware this year, following Sanford Delay and Bass Tightener.

The plugin is one of the most versatile freeware reverbs on today’s market, at least when it comes to 64-bit compatible products. Sanford Reverb offers ultra precise control over early reflections (three early reflection points per stereo channel with time, pan and level parameters), global pre-delay, time and damp controls, MIDI learn, modulation for emulating cavernous spaces and a pair of filters for tone control. The plugin also features freeze mode for creative sound design. Freeze is one of the most fun features you can find in a reverb effect, definitely worth experimenting with. It works great for enhancing the sound of soloed instruments, lush vocals, or even those huge EDM style build-ups.
The CPU usage is surprisingly low for a reverb plugin. During our test on a single core Intel processor in MuLab 6, the CPU hit never exceeded 3% for a single instance of Sanford Reverb. The plugin strikes a nice balance between a quality reverb sound and low resource consumption, which are the two main qualities of a good reverb effect for everyday use in mixing situations.

Marazmator 2.0

Marazmator 2.0, a freeware experimental virtual synthesizer .

Marazmator was written in Delphi and the developer spent over ten years making it (according to the info available in the official product announcement). The fact that the plugin was in the making for such a long period of time is probably the reason why the GUI is so small by today’s standards (only 560 pixels wide). On the other hand, Marazmator is a very stable plugin, which is obviously a positive result of such a long development cycle.

DQ65 Free Dynamic Equalizer

DQ65 is a 5-band dynamic equalizer with a simple yet quite effective workflow. The plugin features two gain controls per band, one for louder one one for quieter parts of the signal. By controlling the value of this two parameters, it is possible to process the signal in ways which wouldn’t be achievable with a standard parametric EQ.

Hysteresis

If you want to create wild glitch-type effects then Glitchmachines should be your first stop. The company makes some incredible paid plug-ins but Hysteresis is one of its free offerings, combining a delay with a stutter module in an effect capable of making robotic timbres and wildly malfunctioning rhythmic patterns.

Hadron Particle Synthesiser

The Hadron Particle Synth is actually a hybrid of several things – as well as being a synthesizer, it’s a sampler and an effect. Like other granulator effects it breaks down sound into tiny pieces, making it ideal for creating strange vocals as well as delicate distortion. Partikkel Audio is so confident this is a leap on from granular synthesis that the company has dubbed the technology “particle synthesis”.

http://www.partikkelaudio.com/downloads/hadron-particle-synthesizer

Fracture

Fracture is another of Glitchmachines’ free effects. It works by buffering the incoming audio then sending it through a filter, three LFOs and a delay, a process capable of shaking your sounds apart. Its interface is a little less intuitive than Hysteresis, but it’s just as capable of creating hyper-detailed sounds. The fun to be had from Fracture is almost endless, but combining it with a saw wave to create massive iridescent lead sounds is probably one of the most fun things you can do with it.

http://glitchmachines.com/downloads/fracture/

Defacer

Audio Assault’s Defacer is the most metal plug-in you’re likely to find, both in name and function. It’s basically a distortion effect, but one that totally mangles any incoming audio as opposed to just making it rough around the edges, and with a few twists of the knobs you can add pretty much any sound and be given a tinnitus-inducing blast of noise. When you need to make some noise but nothing else is quite cutting it, Defacer is one to try.

Klanghem MJUC jr.

MJUC jr. is the little brother of the colorful MJUC.

It's a variable-mu** design with lots of vibe. capable of smooth leveling but also heavy pumping effects. With its two gain stages and interstage transformer simulation it offers a very deep and lively soundstage.
The three-position timing switch not only controls the attack and release times of the unit, but also the slew rate of the transformers and the timing of the other parts of the circuitry, that are directly influencing the generated harmonics (saturation).

Cherry Snare

Acoustic snare drum
This custom snare drum was hand crafted by Ebenor Percussion into cherry wood. This is a warm sounding 14x7 inches snare drum with a 1/2 inch thickness and a 45 degree chamfer, mounted with triple flange hoops dressed by a 2 plies coated drumhead.

It was recorded using 5 microphones (2 on top, 1 at the bottom and a stereo matched pair for the room sound), giving the possibility to mix the final sound from 4 channels. Top and bottom condenser mics were recorded through a tube preamp using NOS vintage 12AX7 tubes driven to a class A digital converter. Top dynamic mic and the stereo room condenser mics were picked up from a top notch soundcard's transistor preamps.
