Any new demo to show ?
I really would like to pull the trigger but there is so few audio example that it's really hard to tell how it sounds.
Please some simple filter sweep with and without the mod oscilator, mono/stereo application, as oscilator etc ... :hail:

It sounds really nice in this demo, any other early adopters who've tried it, any thoughts?

Is any aspect of the filter analog or is it all digital?

Per earlier in this thread it's all digital, but don't worry about the sound on that account--you're in good hands.

The problem with digital isnt the sound quality but latency.

Latency shouldn't be an issue for most (well-written) digital that doesn't involve frequency-domain processing, unless you are doing something that really needs < 1msec delay from input to output.

I wish Ben Divkid would do a demo.. he did an awesome one for the trident (which is one of my fave oscillators). I’ve been gassing for this filter for a while but there’s so little info out there on it!

Precisely.

Latency isn't the FUD it used to be anyway.

I totally feel the dread of piling up latency. Since my DAW introduces 4ms,my speakers are digital as well and add another 4ms, if I then send my Osc's into an all digital filter, which will not have an analog dry path, that will add probably around another 3-4ms I guess. Then I am already at 12, add on top the whole Midi sending and conversion and you will surely feel the lag on a fast tempo. God beware I get the idea to use disting as a VCA.

It might be somewhat irrational, yes, but I do fear latency.
It gets even worse, because many devices don't tell you, how much latency they will add. Fear of the unknown is nightmare fuel for semi-irrational worries.

Not meaning to bash the Linneaus though, I would love one. But I would love a Trident even more.

Ran into this demo recently:

A large part of the filtering (esp. BD) is done on the Evolution-Filter to the right. While being a nice video it makes judging the Lennaeus (and esp. its modulation capabilities) rather difficult.

AFAIK only the BD is going through the Evolution but 🤷

Probably because not a lot of people have it. I'm guessing it's the default thinking of analog filter = better. Would love to hear more examples too.

So, this thing is essentially BP/HP/LP filter with lots of manipulation of the various parameters, an on board modulating osc, and can act as a LPG?

from his website (and as someone else said):
The 808 Bass Drum is isolated and running through the Rossum Evolution, and the 808 Accent trigger is pulsing Control Forge which has a random stepped voltage sequence which is patched to both Evolution and Linnaeus.
