are you intending on using the peaks clone for modulation?
what are your intentions for o&c

I wanted the Peaks for envelopes and LFO mostly (and some other cool tricks with new firmware). The O&C mostly for some flexible CV modulation, something that can do loops and (semi-) random stuff. But maybe Marbles would be better for that (and no menu-diving there), so I haven't decided that yet. There's some Marbles clones like Pachinko that I like.

the pico trio:
You know, the more often you mention your dislike for small modules the more I get it :D I noticed that a lot of modern modules are very dense, many knobs and stuff in as few HP as possible. Tiptop and Mutable went a different route for example with some of their modules and they seem so much more accessible. And I have big hands too, so maybe I should stay away from Pico stuff.

I think the layout of my Neutron strikes a good balance, it has lots of knobs but they're usable and there's actual space around them.

if you go for the mantis & you should then you can get a bigger lpg... an optomix for example... which have more controls and better ergonomics (see below) and seem to be available again... and I'd also look to add a second vco (possibly another ona) and a better submixer(s) with controls for - possibly something modeled after the moog cp3 - adds a nice bit of grit when driven - AISynthesis Hamonic Mixer for example - I'm considering adding another 1 or 2 analog oscillators and will want to add 2 or 3 of these Harmonix mixers when I do...

The Mantis was a great recommendation, will probably go with that. The Harmonic Mixer also sounds interesting.

As for LPGs and stuff, what's your take on the Doepfner modules? They have a quad-VCA and a dual-LPG/VCA for example (A-101-2 and A-130-2, both have a nice layout too.)

Those are great recommendations, thanks!

I'm looking at a bigger rack now (Mantis 2x 104 HP) that would also fit my Neutron, so my ideas may have changed a bit (see my latest sketch here.)

Check out BASTL Softpop 2 - It has so much features in little space. -
Also make noise 0-coast

I get what you're saying, but right now I don't really want a full "voice" module because one of my motivations was to be, well, modular with my setup. I might come back to one of those if I kick out my Neutron sometime in the future though =)

Did you check BASTL Ikarie? - also a nice filter with some tricks on it.

Will have a look, thanks.

If you get BASTL Basil, you can also switch the firmware to the pizza VCO.
BASTL Pizza has many stuff like FM and waveshaping/wavefolding.
Or get pizza first and try out the basil-firmware later.

Didn't realize it's the same module with different firmware, good to know! How does that work actually, does the Pizza use some DSP? Otherwise I don't see how waveshaping and delay could be done by the same circuit.

I have the ONA VCO. I like to mix the different waveforms with Befaco Percall.
You can also use it as LFO.

The Percall looks cool, and mixer + 4x decay sounds convenient too. With my Neutron I already have an LFO and 2 VCOs so there's no need for that right now. Are you satisfied with the ONA?

Ornament and Crime or Disting could also be an idea, to try out or to add different functions with little space.

Yes I'm thinking that too. Any opinion on Ornament&Crime vs. Marbles? I'm having some concerns about menu-diving on the O&C (also something I want to get away from with modular) so Marbles could be more fun for me. Were you able to try both at some point?

your linked rack is private, so unviewable

My bad, I was messing with my settings. There's now versions now: The one I referenced in my reply, and a new one that I came up with after thinking a bit more about my options.

The new setup also addresses some things you mention in your last reply. For example, it now has a pretty cool mixer (MISIO) and only one oscillator (ONA). Together with the Neutron stuff I think it's a nice rig. All this thinking about my setup and going back and forth between options at least left me with a pretty good idea of what I want, so that's nice.

I will definitely have a look at the Mantis too! (The TipTop modules are nice and I like their accessible layout.)


Thanks for taking the time to rely, I appreciate your input! I think you pointed out some things that I wasn't (very) aware of.

this is a common mistake - these cases are really too small for anything other than satellite cases for bigger systems or extremely focused single purpose synths...

Yes, maybe I was too focused on staying small and 62HP is indeed not enough. As an alternative plan, I looked at the Arturia RackBrute 6U with almost 3x the space. (You can find a rack sketch in my profile.)

This might me the perfect size for me actually because it can (for now) fit my Neutron as well. The Neutron supports Eurorack rails and would be a great utility kit for the other modules: 2 VCOs, LFO, VCF, two ENVs, S&H, and even a delay! I can already see that this makes so much sense if I can interface those with my new modules.

Of course the Neutron takes up most of one row, but I can always take it out later when my module collection grows and I need the extra space.

which means no way to generate 'composed' sequences of pitch (there are ways to do this even with a steppy, but not without a dedicated mixer) plus if you want to make 'music' which fits in with other instruments you will almost definitely need a quantizer...

Yes I'm aware of that, maybe I didn't make it clear. My main sequencer is the Digitakt which sends MIDI/CV (and I have a Keystep too.) Hence for now I probably don't need pitch sequencing/quantization in my rack. I was thinking more about having some means of looping CV inputs or envelope triggers that go beyond what an LFO can do. But maybe I'll go with some Marbles clone instead...

I'd want vcas as well... at least a quad...

Good point, but let's compromise on 2 VCAs + 2 LPGs ;-)

  • Cascades and Brooks - I first considered the NANO ONA but now moved on to (part of) the After Later Audio COCO series, with the "Cascades" as the main oscillator and "Brooks" as secondary.

I think 2 oscillators in this size case is too many... and you probably need more modules to support them... a mixer for example

I forgot about a mixer, it's good that you bring it up. As for oscillators: The Brooks interfaces nicely with Cascades and doesn't take much space. I figure that additional VCOs would be great for wave-folding (and also for LFO purposes). But actually, now I'm thinking of ditching the Timber for the Valley by After Later Audio, which is also part of their COCO series.

hmm... I suggest some time spent thinking about the contents of my signature...

So you're telling me I need more controls/utilities? I added a bunch in my new rack, and then I'd now also have the Neutron. That ought to be enough for my first steps.

I take it you have an external mixer for end of chain mixing?

how are you going to raise the levels of the external synths to modular level fir processing?

Yes I run my other synths into an external mixer to get a line out/headphone signal. Eurorack output would plug into that as well. But like you said, I'd want a mixer in my rack for some down mix/level adjustment for sure.


Hey all, first time posting here. This page is awesome btw =)

Note: For some reason the auto-generated preview picture is missing some modules, so here's a screenshot instead.
Eurorack idea v2

So I'm a beginner to Eurorack but the idea has been spinning around in my head for quite some time, basically ever since I got started with analog synthesizers a few years ago. Now I'm at the point where I seriously want to get started, but I would appreciate some help in finding the right modules.

My goals:
- Small setup, both to save space and to enforce some limit on myself regarding complexity/spending => Intellijel 4U 62HP case
- Flexible setup, since I don't have "one" preferred style - I just love to experiment. I just need some oscillators, filters, modulation and maybe sprinkle some delay on top.
- Room for expansion, because I probably want to add a module or two later when I'm more familiar with my setup. For now there should be 8-10 HP left in my rack.

My ideas:
- Steppy and Alan - CV sequencers would be helpful to get some nice loops. The "Steppy" provides the basics, while the "Alan" adds randomness when needed.
- Passive LPG - All my other synths use VCAs, so here I'm going with two LPGs instead.
- Rainier - I was first looking at the NANO Quart or Intellijel Quadrax, but the former seems a bit low on control options and the latter is quite large. Then I found the "Rainier" - it's small, has lots of features, and 2 outputs.
- Cascades and Brooks - I first considered the NANO ONA but now moved on to (part of) the After Later Audio COCO series, with the "Cascades" as the main oscillator and "Brooks" as secondary.
- Forbidden Planet - I heard some nice things about this filter and it should be sufficiently different from "typical" VCFs, opening some possibility for experiments. Also with all the COCO outputs, it would be interesting to use the multiple inputs that the "Planet" provides.
- Timber - I wanted more sound-shaping options than just the filter, and what would be a better match for the west-coast LPGs than a wave folder? This one seems nice, doesn't take much space, and has lots of options with not too much complexity (?)
- Basil - Finally, a stereo delay effect to add texture and rhythmic complexity to my patches. It seems to offer a lot in a small package.

My current setup:
- Elektron Digitakt (main controller, drum machine, sometimes basslines)
- Novation Bass Station II (mostly basslines, sometimes glitchy stuff)
- Korg Minilogue xd (basslines, melodies, polyphonic stuff, sometimes microtones)
- Behringer Neutron (whatever I can think of, it's fun to experiment)

Note: The "user" oscillator on my Minilogue runs some Plaits/Tides oscillators with limited control capabilities. For details see my Github project where I added some features to the original code. I would probably consider these in my rack as well, but they're kinda covered already elsewhere in my setup.
