Which MI modules are purely analogue?

Howdy. I’m just a few weeks into my Eurorack journey, so forgive and forget if this is off the mark…

My main reason for taking the Euro plunge was to infuse my software synth work with some “buttery” analogue sound. Given that, I was surprised to see how many Eurorack modules include digital elements.

I gather that some MI modules are either analogue, digital, or a mix. Is there a list anywhere of which are which?

Additionally, I’d be interested to learn more about how the digital processing is used in terms of signal path. For example, is the digital data flow used solely as CV processing, or does it directly produce/process audio as well?

Thanks a bunch.


These are all purely analogue, but the majority of the are slumping plumbing modules, except for the Ripples (Filter) and Shelves (EQ)

All of the Mutable sound generators are almost completely digital.

That said, “Buttery” is not a feeling I connect to the MI modules i own. Rather clean and and defined. Though Elements can give you some fat brass and heavy bells. And rings the same, as I understand

A quick Google of “slumping” didn’t shed any light.

Woups, Should have been Plumping. As in utility modules. Attemuverters, digital/analog logic, Multiples, S/H. Take a look at the Kinks, Links, Veils, Shades quartet of awesome.

i wouldn’t call blinds a ‘plumbing’ module. among many other things, it’s a fantastic-sounding ring modulator.

and while ripples may not sound buttery to some, i’m sure that everybody will agree that it sounds extremley creamy. there’s definitely some yummy dairy product involved. :wink:


It is definitely not meant as a degrading term. I think anybody with a modular system knows that infrastructure is the key. The balance in packing utility and playability together makes a system an instrument.

Eurorack isn’t so much about buttery analog sound. It’s more a complete different way of sculpting sound and composing. It doesn’t matter really if modules are digital or analog. All the communication between them is in analog CV gate or audio signals.
But you could go and look for buttery analog modules of course. I would look for modern versions of vintage stuff for that. The Frequency Central stuff based on the Roland 100m for example.


That’s a very bad reason to go into Eurorack, or modular in general. It would make more sense to get a few vintage pieces of gear.

Actually, even that wouldn’t really make much sense if you’re interested in a specific sound only, and not in the nice feeling you get from looking at and handling hardware. You can get excellent digital models of pretty much any relevant type of analogue sound generating or processing gear.

Yes. I am getting that. And I do indeed love the look and feel of the hardware. But even more to the point, I like how it makes me rethink the creation process. I’m a hands on kinda guy, so my new rack is serious food for my head and soul.

Understood. Fortunately, sometimes good things happen for the wrong reasons. I’m all in now, butter or no.

Analog: Blinds, Ears, Kinks, Links, Ripples, Shades, Shelves, Veils
Analog signal path controlled/modulated by digitally generated CVs: Frames, Streams
Digital: Branches, Elements, Grids, Rings, Tides, Warps, Yarns, Braids, Clouds, Edges, Peaks


In that case, don’t worry and keep buying. :wink:

That’s what I’m worried about. :grimacing:

Anything can be made to sound buttery analogue by recording it to tape and then back to the computer again.
Or you can get a series 500 lunchbox, fill it with a bunch of colour palettes and fill those up with all the analogue buttery goodness in the world. Then pass all the signals through that and enjoy.
Analogue isn’t always all analogue, digital isn’t just digital and butter sometimes is just a dead crab.


There isn’t even any need to go outside the computer at all. If you’ve got a decently specced computer and you’re willing to spend a few bucks on some good plugins, you can get your digital box to sound as buttery analogue as your heart pleases.

Soundtoys, Modnetic, U-He’s Diva, Repro, and Presswerk, Roland’s vintage plugins, NI’s Monark and their solid and tube modelled effects, the UAD stuff if you want to spend the big bucks, etc. etc.

Can I get this as a tattoo?


I’ll do it for you :smiley:

Sure, go ahead but make sure to send me a photo! :smiley:

There’s different flavours of digital too.

DSP - specialised processor running code to generate/process sound.
Dedicated digital circuit - using a digital circuit to generate/process sound.
FPGA - using a programmable chip to create circuits to generate/process sound.
CPU - using software on a normal computer processor to generate/process sound.

Plus you can also use combinations of the above and combinations of the above with real analogue VCA+VCF.

Nobody tell my guitarist friends how much I love my digital modules…that they think are analogue because of the patch cables…shhhh!
