Empress Effects ZOIA Euroburo
Infinite modular canvas in one Eurorack slot
34 HP Eurorack module
The ZOIA Euroburo is a fully featured modular synthesizer in a single Eurorack module, offering an open canvas for building custom effects, synths, and instruments from modular building blocks. It combines FM synthesis, CV tools, MIDI tools, audio effects, and interface options into one platform, allowing users to connect modules via a visual grid interface and create anything from guitar pedal effects to generative synthesis patches.
Features
- 8x5 button grid for placing and connecting modules visually
- Up to 64 pages per patch, each representing one full grid of modules
- 64 patches stored in internal memory
- Modular signal routing: audio and CV connections between any modules across pages
- FM synthesis, oscillators, VCAs, filters, LFOs, ADSRs, sequencers built-in as modules
- Audio effects modules: reverb, delay, phaser, chorus, flanger, vibrato, distortion and more
- Analysis modules: convert audio to CV signals
- 4 CV inputs with configurable voltage range (-5V to 5V, 0V to 5V, 0V to 10V)
- 4 CV outputs with configurable voltage range
- CV input clock filters to suppress ambient noise
- CV input and output transpose settings (A or C scale)
- Stereo audio inputs and outputs (4 total each)
