Equator2

Equator2 stands as ROLI's comprehensive approach to MPE-enabled sound synthesis, built on a modular architecture that prioritizes flexibility over prescriptive design. The instrument centers on six independent source slots, each capable of hosting one of four synthesis engines: wavetable oscillation, sample playback, granular processing, or FM synthesis. This architecture allows for genuinely complex timbral layering, though the utility depends entirely on your willingness to engage with its depth.

The wavetable engine draws from an extensive library of single-cycle waveforms and morphable tables, providing the expected harmonic material for traditional synthesis work. The sampler integrates a curated collection of multi-sampled instruments ranging from acoustic instruments to vintage synthesizers, with straightforward drag-and-drop functionality for custom samples. The granular engine offers genuine creative potential, enabling time-stretching and texture generation through grain manipulation, scanning, and randomization controls.

Each source feeds through its own multimode filter before routing to two global filter stages, providing substantial tonal sculpting capacity. The modulation architecture supports typical LFO and envelope sources, though the documentation suggests deeper possibilities for experienced sound designers.

Equator2 appeals primarily to producers working with expressive controllers and those requiring MPE functionality within a single instrument. Its modular design prevents it from excelling at any single synthesis technique, but this generalist approach serves well for hybrid sound design. The preset library is extensive, though deeper engagement demands significant parameter exploration. It represents a solid evolution from earlier ROLI instruments, particularly for users already invested in the MPE ecosystem.
