This plugin is a step sequencer that also happens to have a chord workflow. However, we will be talking about the sequencer a little as well. Stochas also works by starting with a scale. The plugin will apply the scale’s notes to the keys of the step sequencer.
Next, you can start adding notes on the step sequencer as desired. The exciting thing about this plugin is that it can also trigger notes based on probability. So, if you have two notes layered simultaneously, you can tell Stochas to play only one, choosing randomly. You can also have multiple chains of notes playing based on probability.
Key features:
- Detailed Features
Every feature in this plugin has many options for total flexibility. For example, you could even use this plugin to program drums after you set up the note mappings. And with probability-based programming, your drums or melodies will never sound monotonous. - Poly-rhythmic
A single instance of Stochas supports up to four individual patterns with its own time signature, step count, and playback speed. It can create interesting melodies and rhythms that are highly dynamic, especially for laidback-style music. We recommend trying it out on trap and hip-hop melodies. - Themeable Interface
There are multiple themes available for this plugin, so you can customize its look the way you like it. - Chord page
The Chord page of this plugin contains various chord shapes, including triads like major and minor to advanced shapes. You can drag and drop one of those shapes into the step sequencer, and Stochas will attempt to place it appropriately within the chosen scale. If any notes are incompatible, it will simply delete those notes. - Deep programming capabilities
Apart from its step sequencer, the plugin also has many other features like multiple midi channels, multiple patterns, velocity and groove modifiers, etc. Exploring everything in this plugin can be a tremendous amount of fun and a source of creativity at all times.
Compatibility:
Stochas is available for Windows 32-bit and 64-bit, macOS 64-bit, and Linux 32-bit and 64-bit. It comes in VST and AU formats.
Summary:
With so many features comes overcomplexity, and Stochas does suffer a little in that regard. If you prefer simplicity, this plugin offers the opposite. However, if you are adventurous and like to experiment with music, we recommend playing around with this plugin — perhaps it could be the ultimate source of inspiration for you.
16. Chow Kick
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. This functionality allows for easy integration of the kick drum with other elements in the song and helps match the kick drum to the composition’s key.
Compatibility:
This plugin is available for Windows 7 or higher, macOS X 10.12 or higher, and Linux, 32-bit and 64-bit. It comes in VST 2/3, LV2, and AU plugin formats.
Summary:
If you’re looking for a flexible and distinctive way to achieve a good-sounding kick drum, Chow Kick is your go-to. Thanks to its circuit modeling, ChowDSP succeeded in emulating an analog drum machine.
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
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-bit, macOS 10 or higher 64-bit, and Linux 32-bit or 64-bit. It comes in VST 2 format.

1. u-he Diva
Diva, a legendary analog-style synth plugin by u-he, sounds similar to real analog synths.
Overall, Diva is an easy plugin to navigate. The plugin gives you five different types of oscillators, four kinds of high-pass filters, five main filter options, and three types of envelopes. You’ll find LFOs, the effects, and the available controls in the lower panels, such as sync, pan, and tuning.
Additionally, there are individual menus for modifications, trimmers, scope, and presets.
Key Features:
- Oscillators
Each of the five types offers a slightly different GUI, which can be confusing. Other than that, they all sound incredible. For example, in the Voltage Controlled Oscillation area, the plugin gives you three options. A CPU-hungry Triple VCO with FM controls, a multi-wave Dual VCO with PWM, and a CPU-friendly Dual VCO Eco with ring modulation. In addition to those, you get a DCO, a single oscillator with a flexible sub-OSC, and a Digital oscillator, which offers several types of waveforms. - Filters
The heart of Diva is its filters. U-he has modeled all five units after a more significant number of classic hardware and, though the controls are similar, each has its unique flavor. For instance, VCF | BITE adds beautiful resonance by increasing the oscillator volume by 10%. - Oscillator Voice Detune
Voltage oscillator synths detune slightly due to component wear, creating a natural effect that is almost like a soft chorus. To simulate this, u-he went above and beyond and gave us the Oscillator Voice Detune panel. You can access it by clicking the Trimmers section at the GUI’s bottom. There are three knobs for each of Diva’s voices, and you can fine-tune them to find your sound. Additionally, you get a “Detune Amt” knob below in the same panel, which controls the global detune.

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.
