1. Matt Tytel Helm (Made By the Creator of Vital)

More Info & Download

Matt Tytel Helm - Top 7 Plugins For Dubstep (With 11 Best FREE Effects & Synths) | integraudio.com

Helm is a great subtractive soft-synth to create all EDM genres, which comes with 200 presets.

It has two oscillators with interesting waveshapes and 32-voice polyphony and is connected via a mod knob, which is a great way to alter the timbre of the oscillators. In addition, it has switchable modules, a filter, a filter envelope, two mono LFOs, one poly LFO, a modulation envelope, and a step sequencer. 

Key Features:

  • Four oscillators.
    Helm includes two main oscillators that come with a wide range of shapes. There’s a mod knob between them so that you can blend them. The knob can be modulated for some extra control. There are also sub and noise oscillators that offer further sound design control. A mixer helps blend all these oscillators and can also be modulated.
  • Powerful dedicated formant filter.
    Helm includes a feature that’s not usually found in free synths: a formant filter. The formant filter has an X/Y pad to help you visualize the filtering, and sounds excellent. It’s particularly useful for creating Dubstep’s signature wobble sounds. You can modulate its parameters through the LFOs provided for some genre-accurate sounds.
  • Multiple modulation sources.
    Helm includes multiple modulators, like two LFOs, a Poly LFO, amplitude and filter envelopes, a modulation envelope, a step sequencer, and keyboard modulation knobs like aftertouch, note, velocity, random, pitch wheel, and mod wheel. Each of these modulators has the Helm logo included in its interface. By clicking on it, sliders appear underneath each parameter that can be modulated, and by dragging them, you can set up modulation settings. It’s a very easy and clean interface.
  • Functional effects.
    Helm includes four effects: delay, reverb, distortion, and stutter. All of the effects parameters can be modulated for extra control. The stutter effect is especially eye-catching since it’s not usually featured in software synthesizers. It is excellent for creating glitchy sounds or adding moments of unpredictability to your patches.

Compatibility:

Helm is available on GNU/Linux, Mac OSX, and Windows, in LV2, VST, VST3, and AU formats, or as a standalone synthesizer.

Summary:

Helm is an excellent free synth. The oscillators and effects are great, and their true power lies in features like the stutter effect, formant filter, and modulation system. The fact that it’s free makes it even more appealing since you can customize and redistribute it. I’d suggest this plugin to every beginner producer looking to start Dubstep music production.

Michael Ourednik Argotlunar Review - 11 Best Granulizer Plugins | Integraudio.com

Argotlunar by Michael Ourednik is a multi-fx, delay, filter, time-stretcher, and a granulizer plugin.

Argotlunar is designed specifically as a real-time delay-line granulator. It does an interesting job of creating an exciting sound design from an audio stream. In this granulizer, you can control the duration, panning, delay, amplitude, glissando, pitch, envelope, and filter of the grains. The grains are then mixed together and sent for output.

Key Features:

  • Grain control
    Argotlunar operates in real-time and functions as a granulator, breaking the incoming audio stream into short grains. Each grain can have random settings for various parameters, including amplitude, panning, duration, delay, pitch, glissando, filter, and envelope. These settings allow for intricate and detailed control over the sound. In addition, it can play up to 20 grains simultaneously, offering extensive possibilities for sound layering and texture creation.
  • Feedback Functionality
    The output of all grains is mixed and can be fed back into the main input, enabling you to create chaotic, densely layered, and distorted sounds.
  • Synchronization with Host Tempo
    Time-related parameters can be synced to the host tempo, making it easier to achieve rhythmic and pulsing textures synchronizing with the project’s tempo.
  • Quantization of Pitch Parameters & Correlation of Parameters
    Pitch-related parameters can be quantized, allowing for harmonic and melodic effects and adding musicality to the granular synthesis process. Many parameters in the plugin can be correlated, allowing for complex and interrelated sound manipulations. For example, filter cutoff can be correlated with pitch, resulting in higher cutoffs for higher-pitched grains and vice versa.
  • Filter and Envelope
    The plugin features a 12dB state variable filter, which offers high-pass, band-pass, low-pass, and notch filter types. Additionally, it includes a parabolic grain amplitude envelope.

Compatibility:

Argotlunar is available for both Windows and Linux operating systems as VST plugins. Additionally, it is also available as an Audio Unit (AU) plugin on macOS.

Summary:

Argotlunar is a powerful tool for sound designers, producers, and experimental musicians who want to explore unique and surreal audio transformations through real-time granular synthesis. Its capabilities and flexibility make it valuable to any creative audio processing toolkit.

Based on creative physical modeling of old drum machine circuits, ChowDSP brings this unique kick drum synthesizer.

Chow Kick offers practical parameters for adjusting the overall body, tone, and fundamental frequencies within two simple sections that allow you to control and monitor your synthesized kick drum entirely.

Besides the factory controls of Chow Kick, you can extend its functionalities as it’s open-source software. So if you know how to code and have some knowledge of DSP, you have a good starting point to create the kick drum plugin of your dreams.

Key Features:

  • Pulse shaper
    Within the pulse shaper section, you can find a set of parameters to generate a synthetic pulse whenever the kick drum is triggered. Here, you can modify the width and maximum amplitude of the generated pulse. Then, you can modify envelope parameters like decay and sustain. Lastly, you can set the number of polyphonic voices the kick synthesizer uses with the bottom left “Voices” control, which can benefit kicks with long decay.
  • Sound-shaping Parameters
    You can add a character with unique parameters: the “Damping” knob controls the global feedback or decay time around the filter. Then, the “Tight” knob is a simplified compressor that lowers the filter’s resonance as the amplitude increases. Next to it, there’s the “Bounce” knob that controls the pitch modulation of the kick drum. Lastly, you will find the “Tone” knob that either accentuates or dampens your kick drum’s high frequencies.
  • Resonant Filter with Nonlinear Modes
    ChowKick utilizes a resonant filter with several nonlinear modes. This filter is essential for shaping the kick drum sound’s body and tonal characteristics. The nonlinear modes introduce various tonalities and harmonics, enabling sound designers to craft unique and diverse kick drum sounds.
  • MIDI Note Tuning
    One of the notable features of ChowKick is its ability to be “tuned” with incoming MIDI notes. You can control the pitch of the kick drum by sending MIDI notes to the plugin.

Plugins with this potential are often pricy or don’t deliver good enough results, but Chow Kick puts itself as one of the best kick drum synthesizers, and it doesn’t cost a penny. Its fully adjustable parameters and wide range of possibilities make it an excellent pick for sound designers.

17. GVST

More Info & Download

GVST GSnap - The 6 Best Pitch Shifter Plugins (With 3 FREE Pitch Shifter Plugins)

With a simple GUI, the GSnap by GVST is a free auto-tune effect that offers subtle or extreme modulations.

Developed by Graham Yeadon, the plugin allows you to correct the pitch of vocals and create special vocal effects, such as the well-known T-Pain or Cher robot-voice effect, by applying extreme settings. However, GSnap’s algorithm suits simpler, more extended notes with steady transitions instead of choppy melodic rap vocals. 

Key Features:

  • Correction
    This section allows you to determine the parameters of when and how the automatic pitch correction kicks in. You can set the threshold in cents and change the amount of pitch correction. A higher amount of correction will result in the reduction of vibrato. Similarly, you can adjust the attack and release to control the smoothness of the processing.
  • Detection
    The detection section lets you change the minimum and maximum frequencies detected. Typically, you want to stay somewhere that provides the best results, which depends on your audio material. However, try 60 Hz (minimum) and 800 Hz (maximum) as a general guide. It should detect the fundamental frequencies well while keeping the formant separated. Likewise, you can adjust an input gate, which avoids random detection caused by recording noise. And the speed parameter changes how fast the plugins detect pitch changes.
  • Tuning
    The vertical keyboard on the left of the parameter lets you select the notes of your key/scale. Furthermore, you can also see a live graph displaying the input notes (red) and output notes (green). And you can make pitch bends, add vibrato, change vibrato speed, and customize the reference pitch in the MIDI section.
  • MIDI Control Mode
    GSnap offers a MIDI control mode, which enables you to fit a vocal recording to a new melody. In this mode, the plugin can snap the pitch to specific MIDI notes in real time while playing a MIDI controller or following a pre-programmed MIDI sequence.
  • Friendly User Interface
    The plugin features a user-friendly interface with 12 knobs controlling all its parameters. These knobs are labeled to indicate their functions, and each has a user-editable readout below for precise adjustments.

Compatibility:

GSnap is available for Windows XP or higher 32-bit and 64-bitmacOS 10 or higher 64-bit, and Linux 32-bit or 64-bit. It comes in VST 2 format.

Summary:

To summarise, GSnap has gained popularity among music producers and audio enthusiasts for its simple yet powerful pitch-correction capabilities, and it has become a valuable tool in many creative audio projects.

u-he Hive 2 - Top 12 Subtractive Synth Plugins (And 8 FREE Synths) | integraudio.com

U-he launched Hive as a soft-synth with a synthesizer architecture similar to Sylenth and Spire, adding their twist & innovation to this incredible software.

Years later, in 2015, they launched Hive 2, with some upgrades and improvements, including the wavetable functionality. It has two main oscillators on which a standard waveform or a wavetable can be loaded, with up to 16 unison voices, two sub-oscillators, three different synth engines, and, most importantly, low CPU usage. Yes, the plugin is light on CPU, given its vast functionality.  

Key Features:

  • Extensive Synth Engine
    You can choose from three different synth engines: Clean, Normal, and Dirty, each of which varies in its internal circuitry, envelope, oversampling, and detuning algorithms, and the choice of models of filters that are used. All these differences bring about a change in the fundamental characteristic of the sound.
  • Huge Sound Bank
    With about 2300 presets from categories like basses, poly leads, mono leads, keys, pads, plucks, etc., the plugin packs a versatile range of sounds for different genres and purposes. You can also save and organize your presets by adding their tags (bright, dark, clean, phat, etc.), features (mono, poly, chord, etc.), and categories. A browser can search the presets by their names and navigate through them.
  • Good-quality Sound Generators
    The two main oscillators in the Hive2 can generate the following waveforms: saw, square, sine, triangle, half pulse, and narrow pulse, along with pink and white noise are of high resolution. You can also load up a wavetable and choose a waveform from that table. In addition, you can load up your wavetables by saving the WAV file of that audio in the same directory as others. Wavetables can be further edited by changing their phase, position, how they are looped, etc.
  • Immense scope for Programming & Processing
    There’s a dedicated display section for the Arpeggiator and Sequence called as “Arp/Seq” section. In the sequencer, you can load up to sixteen steps and add settings like Gate, Transpose, velocity, and Mod. You can use the Mod value to assign modulating destinations to the Mod matrix. Two function generators sync the ADSR and adjust its curve as exponential or logarithmic.
    For modulation, you can drag and drop any parameters with a crosshair symbol next to the destination of your choice. In addition, Hive 2 also allows you to quantize your signals using the scale quantizer. Further, there’s an X/Y pad also available for modulation.
    The effects in the u-he are compressor, distortion, chorus, phaser, equalizer, delay, and reverb, and they can be used in any sort that you like. In addition, the effects section has an aesthetic, colorful display that is pleasing to the eyes. Lastly, the Scope (short form for Oscilloscope) section allows you to see the movement of your waveforms by simply dragging and dropping them onto it.
  • Advanced Interpolation algorithms
    Hive provides four different algorithms for interpolating between the frames: switch (sudden jumps between frames), crossfade (smooth interpolation between waveform magnitudes), spectral (smoothly interpolates between waveform magnitudes and phase), and zero phases (like spectral, but phase adjusts each partial to zero first).
  • Structured visual display
    You get a fairly organized structure of the subtractive synthesis process, with everything loaded on a single window, easily switchable tabs and sections like fx, scope, seq/arp, etc., and laid out amps and LFOs and their knobs and sliders. The signals are also easy to route with an easily understandable signal flow.

Compatibility:

The minimum OS requirement for the Hive 2 is a Mac OS X 10.7, a Windows 7+, or Linux. It is available in AU, VST2, VST3, AAX (Pro Tools 10.3.7+), and NKS with 32-bit and 64-bit versions).

However, the latest version of Avid’s toolkit for building AAX plugins is not compatible with the Apple SDK needed to build plugins for Apple’s new ARM/M1 processors. Therefore, the updated AAX versions are not compatible with macOS, Intel CPUs, and Apple M1.

Summary:

The best part about Hive 2 is its low CPU usage, its wide range of scope in its overall functionality, and its well-thought-out GUI. Also, the official manual for the plugin released by u-he is well-made and informative.

There’s a lot that you can do with the plugin, and if you may not understand the process of synthesis and sound design, there is a huge library of presets arranged based on various categories and styles you could choose from.

6. Waves Harmony

More Info & Price (Trial Available)
The best vocal harmonies can be naturally created inside this awesome plugin.

Waves is well-known for producing high-quality plugins and audio software, which come in a variety of versions and choices to suit a wide range of applications. However, any plugin that may improve the sound aspects or make the workflow easier is appreciated, and Waves Harmony is just like that. This useful voice harmony generator has a simple and beautiful UI with clear controls that are entertaining to experiment with in the recording studio or on stage.

Key Features:

    • Eight voices
      Vocal Harmony is an excellent engine with eight separate voices, allowing for everything from a basic doubled-melody to a complicated and rich vocal arrangement for all these eight voices. This is critical and works flawlessly, with a true sound character like what actual vocalists would deliver.
    • Pitch correction
      As predicted, this plugin makes pitch adjustments quickly and simply. You may freely change and vary the pitch of every note, either by accident or by personal desire, with relative indicators on the screen. Feel free to correct any lines or simply repair one erroneous note as quickly as possible.
    • Harmony Generator
      The powerful engine hidden within Vocal Harmony is ideal not just for duplicating a vocal but also for sparking your creativity. The harmony generator may create immediate ideas based on current musical scales, giving your phrases and musical ideas even more authenticity.
    • Formant shift
      This type of vocal plugin typically includes a “formant” preset, which allows you to mimic the actions a human lip makes when talking or singing. Of course, there are other factors to consider when giving a genuine aural experience, but being able to modify how a singer’s lips react to a given phrase adds realism to this replication.
    • Built-in effects
      Although you can always add post-effects to anything you make, having the most significant aspects related to vocal harmony provided in this package is really useful. A separate “Delay” fader controls the effect’s feedback, while an extra “Filter” fader allows you to easily sweep over the frequencies in your music.
    • MIDI controlled
      One of the finest features of virtual instruments or effects such as Vocal Harmony is the ability to connect a MIDI device and play whatever you want. This plugin has complete MIDI compatibility from Waves, which may be quite handy for getting your vocals done correctly with the help of a keyboard, for example.

Compatibility:

This plugin is available for macOS 10.15.7, 11.6.5, and 12.4 (64-bit only) and Windows 10 or higher (64-bit only). It runs in VST, VST3, AAX, and AU plugin formats.

Summary:

Vocal correction software is difficult to use. It’s difficult to create a decent algorithm that sounds nice to the ears, but Waves has achieved it with Vocal Harmony. This fantastic plugin has a wonderful UI design that makes pitch correction and other modifications as simple as possible, with obvious buttons that change your results with the slightest touch.

Unfortunately, due to the high-processing nature of the effect, Vocal Harmony can have a substantial impact on CPU utilization, even when it works flawlessly.
