ZOIA

An open canvas for your sonic ideas. A modular pedal system.

ZOIA is a fully featured modular system in the form of a stompbox. Place modules freely across a grid, connect them however you like, and build anything from a complete virtual pedalboard to a fully functional modular synthesizer.

The only limit to what ZOIA can do is your imagination.

Effects, Synths, and Everything In Between

• 90+ modules onboard, with more added via firmware updates

Oscillators, LFOs, filters, VCAs, ADSRs, bit crushers, envelope followers, overdrive, delay lines, EQ, loopers — and that's only a fraction of what's available. If you can dream it, you can build it.

• 20+ ready-made effect modules built in

High-quality Empress Effects modules including reverb, delay, chorus, phaser, compressor, overdrive, and cabinet simulator come preloaded. Arrange them on the grid and your personal virtual pedalboard is ready to go.

• Build your own effects and synths from scratch

Want a tremolo? Use an LFO module to modulate a VCA and create rhythmic volume changes. The same logic applies to delays, filters, phasers — any effect or synthesizer can be designed entirely in your own way.
