This must have been some misunderstanding. Of course, this is paraphonic voicing with fixed polyphony, and inputs on Hel are 12TET quantized, hence there are limitations. Customers sometimes enquire with some inacurate preconceptions in mind, and we need to rectify them. But we never meant to suggest Hel was not intended for chords and pads :despair:

Last night my Odessa module was really talking to me. Not in a "sounds like a human voice" way, but in a "what it had to say" way. Here is the music that resulted. From the session notes (which are at the track's webpage in full):

"what seems evidently attributable to Filter 8 is in fact just Odessa. although it is used as a VCF with Odessa, Filter 8 is doing... other stuff."

I made this with Klee, Odessa, an EG and a VCA.

Sound doesn't change and no volume changes when you change "VOICES" with "SPREAD" at zero.
I guess this is normal behavior, correct?

Sound starts changing and volume drops when I turn "SPREAD" knob.
Is this also normal behavior?

Unless you’re using Hel that’s how it works yeah. I think the volume drop is to compensate for the extra voices? It’s only slight for me.

What I understand from the manual and experimentation:
When you click Voices, it goes from 1 to 3 to 5 voices and compensates for the additional voices by reducing the volume. So if the spread is at zero - the change would be almost indistinguishable. When you start to spread the voices out, and each harmonic is tuned at separate microtunings apart, you start to notice the volume reduction as each harmonic seems quieter on its own.

I have the hel expander, and I'm not sure if I'm doing something wrong or there is an issue with my unit...

When I send v/oct CV to any of HELs inputs, nothing happens, regardless of the number of voices of Odessa.

The v/oct input on Odessa works fine. Do i need to patch the same CV into both the Odessa CV v/o input and the Root of HEL?

I've tried sending CV from multiple modules, and it's just not responding : (

Cool. Some nice tame sounds in there. Beautiful.

Question now that this module has been out for some time. How are you guys liking the Odessa after having it for a while? Is there a wide range of sweet spots? A lot left to explore or does it feel limited???
Weed only gives you the illusion that it’s enhancing your creativity.

Yes lots of sweet spots. I’m very happy with it. I think it really shines and becomes really interesting when FM’ed.
I think it will stay in my system for years to come. Yeah, lots left to explore, once of the most unique oscillators there is.

I love this module. It's far more versatile than I initially thought. Subtle modulation and fine tweaking along with separate outputs for the odd and evens bring out a whole range of sounds, particularly when using Hel. e.g. Here the odds are going through a low pass filter, the evens through a high pass and a Milky Way (hence the bloody noise):

Its also one of my favorite modules!

In the VDO "Schraubstock" I used 2 Joysticks simultaneously
to "drive and dive" through the Soundspectrum of the Odessa.



Sorry for the guitar :mrgreen:

yes, I do really like some of its tones when only paired with an envelope or LFO, but it sounds truly amazing with a very light touch of exponential FM from a lower frequency audio-rate sine. the results from modulating the comb section when you have that going makes it a keeper for me!

Hey, so dumb question for the group. I have the Odessa/Hel and have a Lipsk arriving today. Do I connect it to the "IN" or "OUT" line of the Lip? I'll have Drez/Jena coming someday soon too, but for now this is the setup.

I had the exact same question and the fine folks at Xaoc told me the OUT line of the Lipsk should plug directly into Odessa. Have fun with it!

Awesome. I'll give that a try. Hopefully any minute now. Thanks!

How are people using their outputs? Are you mixing the root+odds+evens? Or just using one output depending on the texture you need?

I’m often processing the odd and even separately. Perhaps opening VCAs or filters using separate envelopes triggered by different rhythm clicks. Bouncing from one to the other.
New track! Drum synthesis heavy, melodic piece using Instruō harmonàig and Cš-L. 🐡

One thing to bear in mind with the odd & even outputs is that the odd and even output can essentially be switched using the harmonic bank knob (if I'm not mistaken), so the naming of odd and even is kind of arbitrary. With this in mind, it really depends on use cases.

Often I'll use one out as my main meat and potatoes of a sound but then mix in the other, with a high harmonic factor to bring in a bit more of the higher partials, without dominating the sound. I'm also a big fan of using a switch to jump between the odd and even outs on each note, especially with careful modulation of the harmonic bank and factor. You can start to have two lines play off each other in interesting ways without too much effort.

Another thing I realized in my last session with Odessa is that it might soon become one of my favorite drum machines haha
Tight snappy env into exp FM, a tiny touch of lin FM to add a bit of fuzz and boom, you're away.
The fun starts if you pop a VCA in between the lin FM and you can start to control how much FM you want on each step, going from super harsh noise (snare/hats etc) to really lovely tonal kicks and toms. You can take this a step further by manipulating the separate outs individually and pretty soon you can have a whole rhythm section going. Haven't got to fiddle too much with this idea yet but has been super fun so far.

Also I think it was mentioned before but, using a ring mod with the two outs can yield some interesting stuff as the two outs are always closely related harmonically.

Odessa was actually my first main oscillator (beside the pico system III) and initially I was maybe a little underwhelmed as if you don't use your imagination it can sound very 'samey' but dear god, invest a bit of time and play into and it just opens up worlds of sound!

Ah, that's a smart idea! I was thinking of something like Waver, similarly, and doing VCA mixing between the two or stereo trickery with it. But I've also been exploring cases of just using odd, or just using even, too - it feels a little odd not using all the outputs though :)

Would love to hear some Lipsk (or other liebnitz modules) with Odessa. Can’t quite imagine what it sounds like.

Some tips from earlier in the thread:

* Remember that the root is included in the odd and evens, the root output is more of a convenience for tuning and syncing other oscillators
* Since the root is included equally in both, you can add one output to the inverse of the other output to get a signal with only the harmonics and no root

I have mine permanently into half of a Quadratt so I can dial in how much of each, easily invert, then either add together or keep them hard panned.
