Greenland by OVM Plugin is a free synth VST plugin for Windows that combines subtractive synthesis with a 16-step sequencer, chord generator, arpeggiator, randomization tools and built-in effects.
Released for the KVR Developer Challenge 2026, Greenland is designed for producers who want more than a basic virtual analog synthesizer. Its two oscillators, sub-oscillator, seven filter options and modulation system are supported by composition tools that can generate sequences, chords and new preset ideas directly inside the plugin.

What Is Greenland by OVM Plugin?
Greenland is a free polyphonic synthesizer for Windows available in VST2 and VST3 formats. The instrument combines a traditional subtractive synth architecture with tools for generating melodic and harmonic ideas.
Producers can create sounds manually or use the randomizer to generate new settings. The built-in sequencer, chord generator and arpeggiator also make Greenland useful for quickly creating patterns without leaving the instrument.

Two Oscillators and a Sub-Oscillator
Greenland begins with two main oscillators, each offering its own modulation possibilities. A shared oscillator section provides additional tone-shaping options, while the sub-oscillator can reinforce the low end.
This structure makes the synth suitable for basses, leads, pads, plucks and electronic sequences. The sub-oscillator is particularly useful when a patch needs additional weight without adding another external synth layer.
For House, Techno and electronic music, producers can use the main oscillators for harmonic character and keep the sub-oscillator focused on the fundamental.
Seven Filters and Three LFOs
Greenland includes seven filter choices covering low-pass, high-pass and band-pass responses. The filter section has its own envelope as well as keyboard tracking and velocity control.
Three LFOs provide additional modulation. The third LFO can also be delayed, allowing movement to begin after the initial attack of a sound.
This can be useful for leads and pads where vibrato, filter movement or another modulation effect should appear gradually rather than immediately.
One-Click Preset Randomizer
The randomizer is one of Greenland’s most useful creative features. A new preset can be generated with a single click, and producers can choose which sections of the synthesizer are included in the randomization process.
This means the entire sound does not need to be replaced every time. A producer can keep part of a patch and randomize another section to generate variations.
It is a useful workflow for overcoming preset browsing fatigue and discovering combinations that might not appear through manual programming.
16-Step Sequencer
Greenland includes a built-in 16-step sequencer with randomization and scale-based tools.
The sequencer can generate random patterns and harmonize them to major or minor scale modes. Individual steps can also slide into the next pitch, which is useful for basslines, acid-style sequences and melodic electronic patterns.
Four modulation targets can be controlled from the sequencer, allowing a pattern to change more than pitch alone.
For electronic music producers, this turns Greenland into both a synthesizer and an idea-generation tool.
Chord Generator and Arpeggiator
The chord generator can create four-part chords from a single note. Producers can choose the number of voices and different inversions, while the chord can be harmonized to fit each degree of a major or minor scale.
This can be useful for producers who want to experiment with chord progressions quickly without programming every note manually.
The chord generator can also work with the built-in arpeggiator. The arpeggiator can be used independently, although it cannot run at the same time as the sequencer.
These tools make Greenland particularly useful for House, synthwave, melodic electronic music and other styles built around repeating chord or arpeggio patterns.
Built-In Effects
The synthesizer includes five standard effects with full controls as well as a three-band equalizer.
This allows patches to be shaped inside Greenland before additional third-party plugins are added in the DAW.
For faster sound design, producers can build a patch, add movement, create a sequence and apply final tonal shaping from one interface.
Creative Uses
- Create basslines with the 16-step sequencer
- Generate chord progressions from single notes
- Build arpeggiated House and synthwave patterns
- Use the randomizer to discover new synth patches
- Create pads, leads, plucks and electronic textures
- Generate scale-based melodic ideas quickly
A useful workflow is to generate a random patch, keep the most interesting elements and then refine the oscillators, filter and envelopes manually.
The sequencer and chord tools can then be used to create musical ideas around the finished sound.

Final Verdict
Greenland by OVM Plugin is a feature-rich free synth VST plugin for Windows producers who want sound design and musical idea generation in the same instrument.
Its combination of two oscillators, seven filters, three LFOs, preset randomization, a 16-step sequencer, chord generator, arpeggiator and built-in effects gives it more depth than a basic free subtractive synthesizer.
For producers looking for a free synth VST plugin, a free VST3 synthesizer or a creative instrument with sequencing and chord generation tools, Greenland is a strong free download from the KVR Developer Challenge 2026.
