Xaoc Devices Odessa | Full guide and patch ideas for additive synthesis
Музыка
Odessa, by Xaoc Devices, is one of my favourite modular sound sources. At the time of recording, it’s been available for well over three years, but as far as I can see it’s still pretty much the only Eurorack voice of its type - a one-knob-per-function, five-voice paraphonic, digital additive oscillator - and I think it’s often still a bit misunderstood.
So I thought now might be a good time to take a fresh look at Odessa and see how it stacks up in 2023. If you’re an owner who hasn’t used it for a while, I hope it inspires you to dig in again, and either way, I hope you just enjoy some of the sounds and maybe learn a bit about additive synthesis in the process.
Note: I’ve done a few videos in collaboration with Xaoc Devices recently, but this isn’t one of them. I bought Odessa with my own hard-earned cash last year, so it’s not sponsored - I’m making this purely as a fanboy and I have no other agenda.

I have an Odessa, I used it for drones and love it, but I knew there was a lot more to it. This video not only convinced me to go dive back in, but also grab some Leibniz modules. Thanks Tom!

It’s a been a favorite of us since it came out. Although fully digital it often produces very 70’s Kraftwerk or Michael Rother type of sound.

Ha, I did know that I heard the Odessa in your musicl output. Some things just stick out (nicely!) - great music btw.
Odessa is so underrated. You can get such a wide variety of sounds out of it; so many sounds that I could never even come close to with other voices.
Wow! What a unit. Just looking at the knobs and I/O, I wish I had known about this when I was doing synth works. Even monophonic I'd have had two. Eurorack IS alive and well. How delicious. Make a great noise, people!
This is one of those videos that got me patching in the first 10 minutes, and then I missed the rest while exploring... Now I'll have to watch it again!

Perfect explanation of this module here. I actually understood it. So glad you had that example of using the Leibniz bus (in a musical way) at the end too.
what a tour de force video (i don’t even own this module) - consciousness-expanding, thanks Tom
Brilliant video as usual. Absolutely love seeing someone else enjoying the Odessa as much as I do, especially using it for weird percussive sounds, one of my fave things! Odessa is still my favourite voice I own.

Well, I have to say you have some wonderful patches and draw something special out of the Odessa. I had one for over a year and produced a couple tracks with it, but unhappily I ended up selling it simply because I couldn't removed the fundamental from the incredibly great sounds achieved with this great additive VCO. It drove me nuts in the end. I did the trick of adding the out-of-phase fundamental to remove it but it never quite fully worked and it was a hassle as well. I may try again due to your enthusiasm because additive synthesis is very dear to me. Great vid. Don't stop.

Great video thanks, I have and love Odessa but I admit I've been mostly going by ear and this will definitely help me make better use of it. I do like using a stereo filter after Odessa to tame the harsher sounds and play with stereo field a bit. cheers, Marco

I’ve probably watched this five or six times now, what a wonderful and inspiring tutorial on this quite tricky oscillator. Any chance of a follow up Tom? I know you’ve got more patches in you 😊 Also, I have an Oxi One sequencer which allows you to sequence the Odessa polyphonically (paraphonically?) and it’s amazing as a partner to Odessa and Hel
its been a long i wish this one...next osc for shure
Quite Cortini'esque feeling in the intro. Not really seeing myself getting the Odessa, I'm still always interested in what it can (and can't) do.
Absolutely superb video! Please could you recommend some alternative modules to blinds (preferably with knobs or sliders) I could use to send to the Hel inputs in order to set the note pitches?
@TomChurchill

Thanks! There are lots of options for generating voltage offsets. Off the top of my head, there’s WMD 4TTEN, Noise Engineering Lapsus Os, Intellijel Quadratt… or for even more channels there’s Erogenous Tones LEVIT8, Antumbra ATN8 and Michigan Synth Works F8R. I’m sure there are plenty more - it’s pretty common for attenuverters to have 5V or 10V normalled to the controls so you can use them to produce fixed voltages. Hope that helps!

While the Hel expander as you say doen't have VCA's, you can regulate the number of paraphonic voices in use if you have some extra logic modules and make it so that "silent" voices are replaced with +10V which in many cases will be far above what's audible, especially if you feed Odessa into an LPF with a high cutoff.

Ah, great idea! Will have to give that a try - cheers :)
Thanks so much for doing this!!! A little mis/understood?? More than a little. I bought one based on your other video (later got the Hel) and it seems to have a sweet spot for musical uses but too easy to get atonal. Thanks for the detailed explanation of using HEL. I could not get anything useful w/o using pitch/cv on the odessa. I tried your idea (last video) of multiple sequences (patterns) going into HEL and now that I see how you tuned Blinds, I see what HEL is doing (quantizing the CV) and you really need to tune the input CV. I'm going to have to re-watch your paraphonic patch... I that is what I'm failing at. Xaoc should give you an Odessa, considering your videos are the only ones which actually explain it properly.

@@TomChurchill One question... the patch in the intro. I don't see any explanation of it in the video. I assume its a sequence coming out of Pam's and not being familiar w/ Erfurt - I assume you are using it as a clock divider(?) to generate gate into HEL? Whatever it is, its cool as f@ck. All I find in the Erfurt manual is "generate gate patterns animating the spectrum of Odessa harmonic banks"... so you can use gates into HEL?
@TomChurchill

@@BlackMan614 the intro patch is basically a remake of something I did in my Erfurt video. Check out the patch at around 21 minutes for a full breakdown of that: kzread.info/dash/bejne/pqmMqc6MeNnfhcY.html And you’re right, I’m basically using Erfurt to generate a pattern of gates, taking four of those gates through attenuators to set each to a different voltage, then feeding those into Hel to create different combinations of pitches.

Thanks! The fundamental is always present in the odd and even outputs so I didn’t really need to use the fundamental output in these patches. I think it’s useful for syncing or FMing other oscillators but to be honest I don’t often find much use for it.
Quantized by Hell 😈
Hey Tom, I just picked up an Odessa, and I noticed that partials 9 through 11 can't be turned on individually, but rather come on together as a clump of three. I checked again in your video to see if you have the same thing happening, and it looks like you do, which I believe I can see and hear it happen at around 7:18. I really like the sound of the partials turning on one at a time, but it doesn't seem like that works for the range of the knob. Can you confirm this behavior? And if so, how much does it bother you?
@TomChurchill
9 ай бұрын
Hmm, just checked mine and you're right, that does happen. I tried using external CV too, in case it was something to do with the pot on the unit, but yeah, it behaves the same way. Have to admit I've never really noticed it before - I tend to modulate the spectral tilt more than the partials - so to be honest it doesn't bother me too much. Things get indistinguishable pretty quickly after the 8th harmonic anyway. You might want to drop Xaoc an email to double-check if it's a known issue or if there's any kind of fix?
@allhandsmusic

I like modulating the partials because I love the sound of each turning on and off. And well... that's kind of your fault! It was a selling point for me hearing it happen in this very video. I just sent an email to Xaoc, so I'm curious how they might respond. In any case, I'm still loving Odessa, and I'm keeping it regardless.
