We are working on more Linnaeus video content. Though the high volume of support requests and other inquiries we've been receiving recently has put some strain on the production of new videos, we are committed to customer service.

Yes, definitely need more demos of Linnaeus, for instance by Mylarmelodies, Divkid, Loopop ...

Wave! Thank you for the response. It's great that y'all receive multiple inputs and process them independently. I hope everything stays on Track.

Make sure to listen with stereo headphones or speakers to hear LINNAEUS' filter response modulation in stereo!

So the Response Enable for each channel is: positive per the CV input, an inverse of the CV input, or none at all? There's no crazy mapping/saving of the response per channel, is that right?

There are two sets of buttons. Does the right set allow you to dial in a particular response per channel, while the left positively or negatively engages the CV input?

I have one arriving tomorrow, so I will check, but the manual and demos aren't super clear. :cloud:

EDIT:

So the right set of buttons activate which response is applied to either channel. For example:

Turn the Response/Q Comp knob full CCW (low-pass) and press both buttons so they turn red. Both channels are now in low-pass. Turn both buttons off, turn the knob, it does nothing. If you move it to say, high-pass, and only press the Left button, the left channel is now in high-pass (and will follow the Response/Q Comp knob until disabled, where it will stay in the response the knob was pointed to when the button is turned off).

The left set of knobs is more clear. They each enable changing the Response of each channel via CV (either positively (green) or negatively (red).

Brilliant!!

So just like my trident, the layout is also tailored towards people with baby-sized fingers.

I'm loving the sounds coming out of my recently acquired Trident, I have to say I never had a module that feel this solid, but I'm also suffering the knobs. I wonder if I could replace them with others of a smaller diameter to make my life easier. I also bought a Linnaeus, but I haven't tried it yet...

I would like add Trident or Brenso :) let's see

For people who actually own one: Is clipping an issue if the input signal becomes too hot or if there is high resonance? I don't mean saturation, but actual digital clipping.

I had the Morpheus and you had to watch your input levels a lot with that module, which was one of the many reasons why I ended up selling it. However, the Morpheus had wildly different filter responses, so I get that it's potentially harder to avoid clipping in all situations. I'm hoping that with a filter that is more predictable, it's not as much of an issue. In any case, I'd be very interested in experiences with this - Is clipping an issue with the Linnaeus as well or does it have enough headroom that it's not a problem?

I went ahead and bought one, so I can now answer my own question from above: No, clipping is not an issue, it has a nice soft saturation and can also compensate for the whole range of the resonance automatically.

It is also a beautiful filter. The resonance can get extreme compared to most filters I've used, so it pronounces harmonics in the input signal strongly, which makes FM sound all the more interesting. It bubbles and rasps and creates all kinds of beautiful harmonics. I am finding lots and lots of sweet spots just playing with it on a simple drone. I was a bit worried because of my experience with the Morpheus, but this is the complete opposite: Where you had to be really careful with the morpheus and find exactly the right cube and settings for every input, the linnaeus sounds gorgeous on most things I've fed it so far.

Love to know what u think of that linnaeus.

Was this module named after Carl Linnaeus, the Swedish botanist? I know Dave originally studied biology at Cal Tech.

I just got one of these, I haven't figured out exactly how it works yet but I recorded a quick demo of a little stereo loop I made going into it and I messed around with the knobs while reading the manual. Watch your bass bins / ears for some volume changes: https://soundcloud.com/splitradix/rossu ... C8e3khuMz9

Audio is downloadable as a 44.1kHz 16bit wav so you can get past the Soundcloud streaming audio quality.

I'd love to hear more demo's of this thing, also some simple saw-filtersweep examples. If any owners would care to share?

Here you go - here are some audio demos. In general I find Linnaeus can go from super smooth to super gnarly. Once you get the Mod Index on the go you can get this ring modulator / crunchy sound which works great on most things, but especially sine waves. It's a great filter let down only by the overly large Rossum knobs. If anyone knows of any small options I'd love to switch the attenuators for something narrower - otherwise it's a pecking finger fest.

Watch your levels - there's a lot of sub in the resonant low end (I did remove some as it was just too much).

wow, that sounds really impressive. I like especially the heavily modulated examples, seems like there is wide variation of sounds possible with this filter. Thank you!
