Explore the sounds of Equator

Find the perfect sound

Equator includes hundreds of sounds, and more are coming all the time. From warm synth basses to airy pads, spanning acoustic, electronic, and hybrid sounds. Equator also includes multiple oscillators and FM synthesis, so you can make each sound your own.


Explore endless modulation options

Equator offers a clean, easy-to-navigate interface for exploring multidimensional sounds and effects. Its functions are grouped into the Synth Panel and Modulation Panel.


Synth Panel

Play with oscillators, filters, sample playback, noise generation, and other functions. Generate your sound from a wide range of sound sources and synthesis techniques.


  • Add up to two samples from a large library of high-quality sample instruments, from acoustic instruments like Grand Piano to sampled analog pads and leads

  • Set Equator’s three oscillators to multiple waveforms including classic analogue-style waves (pulse, sine, square, triangle, and sawtooth) and complex waveforms

  • Achieve complex timbres through frequency modulation (FM) on the three oscillators. Shape sounds further with the noise module and multiple filters


Modulation Panel

Add modulation to any parameter — quickly, intuitively, and easily.


  • Adjust in real time the behavior of the Five Dimensions of Touch — Strike, Glide, Slide, Press, and Lift — on a ROLI instrument

  • Adjust movement and time in your sounds through multiple envelopes and low-frequency oscillators (LFOs).


Bring Equator into your workflow

Equator works as a standalone desktop app, or VST and AU plug-in on Mac and Windows. Optimized for MPE-enabled controllers like the Seaboard and MPE-compatible DAWs like Logic or Bitwig, its sounds and effects work with non-MPE instruments as well. So you can bring Equator into any workflow.
