ModulAir by Full Bucket Music 0 (0)


ModulAir is a modular polyphonic software synthesizer for Microsoft Windows (VST) and Apple macOS (VST/AU) written in native C++ code for high performance and low CPU consumption.

  • Fully modular architecture
  • Up to 18 modules per patch
  • 55 module types available
  • Polyphonic Voice and monophonic Master modules
  • Up to 64 voices polyphony
  • External signal processing possible
  • Supports MTS-ESP by ODDSound dynamic micro-tuning
  • TUN/SCL micro-tuning file import
  • MIDI Learn – all parameters can be controlled by MIDI CC
  • Double precision audio processing
  • Plug-in supports Windows and macOS (32 bit and 64 bit)


U-he BeatZille v1.0.2 x64 x86 VST VST3 AU AAX WiN MAC LiNUX [FREE] 0 (0)


Beatzille: little monster
Beatzille is a compact version of our monster modular synthesizer Bazille. Although its condensed feature set makes it the ‘little brother’, Beatzille is still an engaging and capable synthesizer. Power and style run in the family. Digital oscillators, analogue-style filter and flexible patching will keep you busy for a good while before thinking about tackling Bazille.

• Modular architecture
• 2 digital oscillators with simultaneous frequency modulation (FM), phase distortion (PD) and fractal resonance (FR)
• Polyphonic (up to 8 voices), duophonic (split oscillator pitches), legato or retriggered monophonic
• Pitch transpose, drift and glide control
• 1 multimode analogue-style filter with 6 parallel outputs (4× lowpass, bandpass, highpass)
• 2 ADSR envelopes with sustain slope (fall/rise) and 5 trigger modes
• 1 LFO with 3 parallel outputs with various waveforms
• 16-step sequencer with 8 morphable snapshots. 4 output sockets for parallel sequences, envelope triggers and more
• 2 multiplex units for mixing, crossfades, ring modulation or amplitude modulation
• Built-in stereo delay with tape wow, feedback and damping filters
• 1 mapping generator (waveshaper / incrementer)
• Audio-rate signal processors: inverter, rectifier, sample & hold, dual lag generator and quantizer
• White and pink noise generators
• MIDI modulation sources include modwheel, velocity, breath, pressure, key follow, gate and more
• Single-page interface
• Skinnable UI
• Resizable UI from 70% to 200%
• Global preferences page
• MIDI learn overlay and editable MIDI CC list
• Over 160 factory presets
• NEW in v1.0.2: Support for Oddsound MTS-ESP

Small and mighty
Striking the balance between too much and too little, Beatzille is the happy medium. It presents an introduction to modular synthesis and a taste of the power of Bazille without being overwhelming.

Beatzille’s oscillators embrace two digital synthesis methods developed during the 1980s: frequency modulation (FM) and phase distortion (PD). We also added a process we call fractal resonance (Fractalize), which sounds similar to the classic oscillator sync effect when swept.

All three synthesis methods run simultaneously, so you can combine them to create an extensive range of sounds. Beatzille is great at generating weird modular blips and squeaks, but you can even coax soft pads and organic keys from the oscillators—as demonstrated by the factory library. Add modulation for even more sound possibilities.

The filter is a favourite in the sound designer’s toolkit. Cut frequencies, boost others, add texture and colour. Beatzille’s analogue-style filter complements the digital oscillators, providing warmth and drive. And its self-oscillation capability opens up some intriguing sound design opportunities.

Even with a single filter Beatzille offers plenty of creative horizons. The six parallel outputs (highpass, bandpass and four types of lowpass) with multiple modulation options make it easy to create complex, shifting textures.

Beatzille has only one built-in effect, but it’s good one: stereo delay with optional host sync. Push your sound around in space with independent delay times and volumes for each channel. Conjure ghostly echoes using tape-like wobble and filtering or set up endless repetitions. Tweak all controls to find the perfect delay.

Special Notes:
• AAX support on Mac removed temporarily (will come back in next update)
• Updated minimum requirements, CPU needs to support SSE4.2 instruction set
• Linux: minimum required glibc version is 2.28 (otherwise plugins won’t show up)
• macOS 32-bit support discontinued

The Windows installer was improved to prevent common installations issues. Please check the suggested installation paths during installation, making sure the update is installed into the same location as the previous version, and all installed plugin formats are being updated.

Envelope triggering via LFO and sequencer was reworked in order to fix multiple bugs in this area. This means some presets might not sound as intended anymore. We therefore recommend to finish ongoing projects before updating to the new version. Please refer to the “Patch Conversion Tips” file to get more info on how to adjust your presets.

Bespoke Synth v1.0.0 WiN MAC LiNUX [FREE] 5 (1)


Bespoke is a software modular synthesizer. It contains a bunch of modules, which you can connect together to create sounds.

Bespoke is like a DAW* in some ways, but with less of a focus on a global timeline. Instead, it has a design more optimized for jamming and exploration.

Bespoke is a project I started in 2011 as a way for me to learn more about creating music. Instead of putting in the time to learn the intricacies of an existing DAW, I took on a foolhardy exercise to try to build my own. The software is custom built by me and for me, hence the name “Bespoke”.

Bespoke’s core design is to break everything into separate modules that can be patched together in a custom layout, much like a hardware modular. Bespoke is designed to be highly customizable, with the idea that any of the custom layouts that you create will be “bespoke” to you as well.

In a way, Bespoke is like if I smashed Ableton to bits with a baseball bat, and asked you to put it back together.

Fugue State Audio Shapeulator free plugin synth VSTI3 0 (0)



Shapeulator is essentially the product of a modular patching session, and a desire to have the core setup used available for further sound design fun. At the most basic level, it is a subtractive synthesizer, with some additional features that make it especially useful for certain types of pads, fx sounds, and synthetic percussion.

The main features that separate Shapeulator from other analog-style subtractive synths are the waveshaper oscillator and resonator. The waveshaper oscillator is a fairly standard VA osc with a waveshaper that is controlled by another oscillator. This second oscillator can be modulated independently, and creates a sound something like amplitude modulation. The resonator is a stereo bank of tuned delays with feedback, which can also be modulated.


WaveFolder by Martinheterjag 0 (0)


The Wave folder is inspired by west coast modular synths like Buchla and Serge, where you instead of starting with a harsh waveform (Eg. square or saw) and filter it like on a subtractive synth, you instead start with a sine wave or triangle and distort it to get a harsher sound. This VST is folding a waveform in similar ways as serge or buchla modules but is not supposed to emulate them. The wave folder VST will sound harsh and digital and can be used on smoother sounds to add texture or be used on more complex sound sources and open the gates to the realms of heavy distortion an

ZEEK STFU v1.0.4 x64 VST3 AU WiN MACOS [FREE 0 (0)

ZEEK STFU is the best free volume shaper available.

STFU is a super quick to use sidechainer that can be automatically sync’d to host BPM or triggered by MIDI notes and it’s always sample accurate. Using MIDI trigger, you can overcome limitations of very many synth volume envelopes for a myriad of purposes.

STFU can also output CV for use with lots of hosts and modular plugins.

And if that isn’t enough, you can set up 2 separate envelopes and crossfade between them for all sorts of cool stuff.

VOSIMSynth by Austen 0 (0)

VOSIMSynth is a free, fully modular audio synthesizer with a focus on speed, audio quality, and ease of use. Check out the github page ( for more information.

Pre-built binaries for Windows can be found on the github release page, or directly from KVR. Note that these links are currently 64-bit builds only.

Nightly builds (including 32-bit builds) can also be obtained from AppVeyor by visiting the github page and clicking on the AppVeyor badge at the top of the readme.

Also, please note that VOSIMSynth has mostly been tested using (and therefore likely works best with) Reaper and VSTHost / SAVIHost.
