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):
