    Product Description

    Here's what Empress says about the Zoia:

    The ZOIA is basically a modular synthesizer in pedal form. Instead of being a delay effect or tremolo, the ZOIA provides the modules necessary to build a delay or tremolo from the ground up. But since you're the one building it, you can make it do whatever you want. With the ZOIA you can build your own custom effects, synthesizers, midi controllers, and virtual pedal boards. And to make life a little easier, we've created modules for all your standard guitar effects. So for instance, if you want a phaser, you can just plop down a phaser. You don't have to break out the textbooks to learn that they're built out of all-pass filters. (Of course, if you're a nerd like us, you can use the ZOIA to build them out of all-pass filters).

    Key Features

    • 80+ Modules and Growing - ZOIA comes packed with a vast collection of modules to create just about anything you can dream up. With ZOIA the only limit is your imagination!
    • Create your own effects, synths, control devices, and more! - Oscillators, LFOs, filters, bit crushers, envelope followers - these are just a handful of the included modules that can be connected in almost any way imaginable. If you can dream it up, you can create it!

    I have spent a few weeks with this, I know I have only scratched the surface with this, but loving the sounds I am getting from this already. There are hundreds of downloadable patches to get started, whilst you figure out the interface. This is a hell of a learning curve, but very much rewarding once you get the hang of it.

    Any wacky combination of sounds can finally be mine, once I get time to figure out how to use it.

    A whole world in one tiny box If you have the skills/persistence then this box could potentially do anything you want with audio/synthesis

    Replaces 80% of my pedalboard. I can get a lot of weird and wonderful sounds from it. Also works great with a midi controller for synth or as a drum machine. It does take time to master the user interface. But when you get it it's simply genius.

    Amazing pedal and a great learning experience for non synth users. I fully recommend pulling the trigger and getting the zoia even if you are slightly intimidated by it's complexity as you will be glad you did.

    ISO flexible! Easy to program if you are used to modular work flows. Been grabbing a load of community patches on patch storage too, like having a bee pedal every day.

    My new favourite pet. I've always thought musicians/reviewers sounded a bit naff saying "It has loads of personality" about whatever synth they happen to like, but this thing, well - it has loads of personality. I actually love it.
