Empress Zoia

Its my second effects unit. First one was gt guitar pedal, which i didnt like, because it was too noisy. Been fiddling only a couple of times without reading the manual (watched a lot of videos before ordering) and i love it. Made a couple of simple effects patches and quality was impressive. Just listened to my op-1 with lots of modulation and tombola seq randomness through zoia for half an hour - wow! I believe its worth the money for the fx alone. But i love the fact that i will take it a lot further than that. Probably a keeper for life together with op-1 and OT :slight_smile:


I feel the same, not many electronic instruments fall into this category, where they get an almost cult like acclaim, I should imagine it is one of the most rewarding things for an instrument maker.


Damn it, you dudes are tempting the hell outa me. I love the OTO Biscuit as my OT cue out FX unit. But buidling up an OT based battery power rig, the Zoia seems like the ultimate option.

It’s possible I’m still in some kind of honeymoon affair with it, but at the moment it’s the one single piece of gear I have that I doubt I’ll ever sell.

And yes, was very impressed by Empress personally emailing and then following up. I’ve never had that happen before. I took a few minutes to thank the hell out of them for being so responsive and fostering a proper community.

This is the best video I’ve seen for Zoia yet, featuring many user patches:

i caved and received it yesterday. what an incredible device. the audio part seems very intuitive - remarkable UI design…

I am struggling with the MIDI part though - I cant seem to send MIDI out. Is there anything more to it than creating a Midi Note out module and feed it some notes from a sequencer? ( i easily managed to get external clock in, wire it to my gate in for the sequencer - the sequencer sends notes to the midi out module). I’m pretty stuck here…

learned something: I created a midi note out module with a velocity add on - this occupies 3 dots but I only had 2 dots to spare on the page - that means the velocity parameter was kinda hidden so I didn’t notice that it was set to zero and hence, only note off messages got send. something to look out for, it’s not that it just slides onto the next page, it only reveals itself after moving the module over by a dot to give it enough space


That video was SO good. I’ve got loads of inspiration for making some kick ass effects now… I really, really, really need to make some time to play with the loopers and granular effects


Posting (re-posting?) the official feature discussion site. I think you get access as soon as you register your devices:


Lots of good feature discussions going on.

that might be one step closer to clicking the buy button…


I got lost in a hole with the granular module this evening, making some drone-type patches similar to an EHX SuperEgo. It’s not super smooth at the moment but there’s some tasty grab-and-go action… Even with 8 grains, it’s a little ‘clicky’ when traversing the pos. with an LFO.


So that sounds like Zoia Clouds patch?? Did anyone try to emulate something like Clouds from Mutable Instruments?

There’s an attempt on the patchstorage site. I think it’s called Fog…



just a short question, as I don’t have access and not an owner of the zoia: is it planned to have the possibility to load IR (for exemple for the cabinet sim)?

Thanks a lot !

What is this? What do you mean?

Impulse response. Used via convolution algorithm for reverb and speaker cab sim

All right. In my area of work it’s infrared, I had trouble to find another meaning for that.
I love it that I still have so much to learn after 30 years of practicing, listening and reading about music :smiley:


It might do… IDK. TBH, I haven’t played with any of the default stuff! I cleared down and went straight into making my own things.


The short technical explanation: by measuring the response of a dynamic system to an input impulse you can afterwards calculate the response of the system to any other input signal.

So theoretically you can simulate a complex dynamic system (like the reflections within cave) from a single measurement.

Another application of IR is the simulation of analog audio gear. By measuring the impulse response you can afterwards simulate that analog gear digitally.


OK, thanks for the clarification @tnussb.

So @yomanfree what is it that you have in mind exactly when you say the following?

As @yomanfree is also a guitarist, Cab sim I guess! :wink:
Cab sim IR can be short.

IR Reverbs are longer, usually very cpu demanding.

I used IR deferently here, you can use any sample as IR (water sound, drums modulating a river, at 34s, Samplitude Convolution reverb).
