Most software synthesizers are designed around a familiar workflow. You program oscillators, shape them with filters, route modulation, and eventually arrive at a sound that sits somewhere inside your mix. The process is powerful but often static. Once the sound is designed, it tends to behave the same way every time a MIDI note is triggered.
The Equator2 synthesizer from ROLI approaches sound design differently. Instead of focusing purely on traditional synthesis architecture, the instrument was built around expressive performance and multidimensional control. It treats synthesis as something that evolves with the player rather than something that simply triggers when a note is pressed.
At its core, Equator2 is a hybrid synthesizer capable of combining multiple sound engines, deep modulation systems, and expressive MIDI control. The instrument expands dramatically on the original Equator synthesizer, introducing a powerful new architecture designed to support modern sound design and performance workflows.
For producers, composers, and sound designers looking for a synthesizer that moves beyond static presets, Equator2 offers one of the most flexible synthesis platforms currently available.
A Synthesizer Built for Expression
The philosophy behind Equator2 begins with expressive MIDI control. ROLI originally designed the instrument to work alongside the company’s expressive controllers, particularly the Seaboard series of keyboards.
Unlike traditional keyboards that send a single MIDI message per note, expressive controllers support multidimensional input. This allows performers to control parameters such as pitch, pressure, and movement independently for every note played.
Equator2 responds to this data using MPE, or MIDI Polyphonic Expression. MPE allows each note within a chord to carry its own modulation data, meaning one note can bend upward while another remains static or modulates filter parameters independently.
This transforms synthesizer performance into something far more dynamic than standard MIDI playback.
Hybrid Synthesis Architecture
Equator2 is not limited to a single synthesis technique. Instead, it combines several synthesis engines within a single instrument.
Each patch can utilize multiple oscillator types simultaneously, including wavetable synthesis, virtual analog oscillators, sample playback, and granular synthesis. These engines can operate together within layered patches, allowing producers to design complex sounds that evolve over time.
This hybrid architecture makes the synthesizer equally capable of producing analog-style basses, cinematic soundscapes, evolving pads, and experimental textures.
Wavetable Sound Design
The wavetable engine allows the synthesizer to move through multiple waveform shapes during playback. Instead of generating a static waveform, wavetable synthesis scans through a table of waveforms, producing evolving harmonic structures.
This technique is particularly useful for creating modern electronic sounds where movement and texture are essential.
When combined with modulation sources such as envelopes and LFOs, wavetable scanning can create sounds that continuously shift in tone throughout a performance.
Granular Processing
Granular synthesis introduces another dimension of sound design. Instead of playing a sample linearly, granular engines break audio into tiny segments known as grains.
These grains can then be rearranged, stretched, reversed, or scattered across time. The result can range from subtle atmospheric textures to completely abstract soundscapes.
For film composers and ambient producers, granular synthesis offers a powerful way to transform recorded material into evolving sonic environments.
Analog-Style Oscillators
While Equator2 embraces modern synthesis techniques, it also includes traditional virtual analog oscillators.
These oscillators generate classic waveforms such as saw, square, and triangle waves. When processed through filters and envelopes, they recreate many of the sounds associated with vintage analog synthesizers.
For producers who prefer familiar synthesis techniques, this allows the instrument to function as a traditional subtractive synthesizer while still offering advanced capabilities.
Modulation and Sound Movement
The modulation system inside Equator2 is extensive. Nearly every parameter within the synthesizer can respond to multiple modulation sources.
Producers can assign envelopes, low-frequency oscillators, velocity data, or MPE gestures to control parameters such as filter cutoff, oscillator pitch, wavetable position, and effect levels.
These modulation paths allow sounds to evolve dynamically in response to performance input or automated modulation patterns.
For sound designers, this flexibility turns the synthesizer into a complex modulation environment capable of producing constantly evolving textures.
Effects and Sound Processing
After the synthesis stage, Equator2 includes a comprehensive suite of built-in effects.
These effects include reverbs, delays, distortion processors, modulation effects, and dynamic processors. The effects can be arranged in flexible routing configurations, allowing producers to shape the final tone of a patch without leaving the plugin.
Many of these effects also support modulation, allowing parameters such as reverb size or delay feedback to change dynamically throughout a performance.
Preset Library and Sound Design
Equator2 ships with a large preset library created by professional sound designers. These presets demonstrate the full range of the synthesizer’s capabilities, from analog-style bass sounds to expansive cinematic textures.
For producers new to the instrument, presets provide immediate access to usable sounds. For advanced users, they can serve as starting points for deeper sound design experiments.
Because the synthesis engine is fully editable, every preset can be modified or rebuilt entirely from scratch.
Integration with Digital Audio Workstations
Equator2 functions as a plugin instrument inside modern digital audio workstations. It supports common plugin formats including VST, AU, and AAX, allowing it to integrate into nearly every professional production environment.
Producers can trigger the synthesizer through MIDI tracks, automate parameters through their DAW, and route its output into standard mixing workflows.
This integration allows Equator2 to operate as a central instrument within complex production sessions.

Equator2 stands apart from many software synthesizers by focusing on expressive performance as much as sound design. Its hybrid synthesis engines, extensive modulation system, and deep MPE integration allow sounds to respond dynamically to the player.
For producers who prefer static presets, the instrument may feel more complex than necessary. But for musicians interested in expressive synthesis and evolving textures, Equator2 offers a level of flexibility that few plugins match.
As MIDI controllers continue to evolve and expressive performance becomes more common in digital production, instruments like Equator2 suggest where synthesizer design may be heading next.
