Edit: system updated

I have started a new thread as completely redesigned my initial idea based on realisation of the need for more utilities but would welcome feedback on this new idea with the emphasis on experimentation of sound and techno. I would like to sync this to some of my external gear including drum machine so have included the midi outs/ins.

ModularGrid Rack

I have included the pico drums and Tiptop One sample module as although I have a Roland TR8S drum machine, it would be nice to have the option of this as a standalone unit. They are also cheaper than the Morphagene I was initially thinking of!

This will be my first system getting into modular outside of semi modular synths so any advice is greatly appreciated. Also anything else you would add or remove? I was thinking of including a sequencer but for now think some interesting rythms could be generated with what is there.

Quick question: Do I need anything else for audio out to my external mixer for connecting to speakers?

Edits about difficult to find modules in the UK/internet:

  1. Circuit Abbey Invy seems to have been discontinued/out of stock everywhere - is there a similar alternative Dual Attenuverter & Offset to recommend?

  2. Folktek Alter 2 fx modules seems to be US only with a waiting list of about 16 weeks - is there something similar that could work? Although must admit I do like the design of this!

  3. AI Synthesis AI008 also seems to be US only and with shipping works out $151 which is a bit expensive and I dont fancy the DIY kit as have no soldering gear - is there an alternative or could I live without it in this setup?

Finally - how would I connect a Beatstep Pro as an external sequencer to this setup which would also sync tempo (either in/ or out depending on the situation) with other external gear and my computer?


Hi Humanoid01,

By the way, last week I met Humanoid03, a brother or cousin of yours? ;-) Just pulling your leg ;-)

Personally I feel you got a bit too many "sexy looking modules" ;-) Some of them are very nice, I will believe that, but perhaps you should keep that for later when you have more experience with your rack; up to you of course. Think of ditching the Mordax - Data (yes it's nice but straight away buying this one? Is a bit too early I believe), the Plasma drive from Erica Synths? It's pretty large and to start with in a rack, mwah... not so sure, keep that on your wish list, is my advice; and perhaps a few more of that kind of modules.

I would consider one more EG and you might want to consider one more filter to start with. Add also one more empty row to this rack to have some space for the (near) future.

It's easier and better to have an Audio I/O module to "export" your audio out of your rack to your external mixer. From the external mixer take one of the outputs to your speakers. Eurorack modules, the audio signals are of a higher level then audio line levels; so keep that in mind in case you decide not to go for an audio module. I am using the Intellijel Audio I/O and I am pretty happy with it, the only thing it doesn't have is a headphones output. If you need that consider the Befaco - Out v3.

That should do it for the beginning, after that build up experience, at just your opinion on certain matters and then see if those items I asked you to leave it out first, if you still want to have them added. Good luck with it and have fun with modular! Kind regards, Garfield Modular.


Thanks for your detailed response - very helpful!

I agree it makes sense to go for a bigger case and so am now looking at the Doepfer A-100P9 Case PSU3 with 3x 84HP which also has a handle and cover I think which is great - I have updated the build with this in mind.

I took your suggestion for the Intelligel I/O (just what I was looking for - perfect!).

I wasn't quite sure about what to go for in a 2nd filter but the Bastl Cinnamon seemed pretty cool sounding and good value for the size.

I added in an additional Doepfer ADSR.

I know what you mean about the Plasma Drive but its so damn cool - I may in the future move it to its own individual case to use as a distortion for some of my external gear.

For the Oscilloscope - I am a visual person so would like to see what it is happening with the sound that is being created - is there something similar you would recommend that maybe takes up less HP or is a bit more basic? I guess I dont need to monitor 4 inputs at once but maybe 2 waves may be helpful.

One thing I am now not to sure about is I was thinking of using a Beatstep Pro to act as a sequencer and sometimes to sync between my computer and the system - not quite sure how this would connect in this build though?

Also with regards to layout, I am not quite sure what works well - I guess that is the point though of moving things about once you are using the system for optimum efficiency.

@humanoid01 take a look at page 19 of the manual for the Beatstep, it has pitch, velocity, and gate outputs for connecting to your synth and a USB port for your computer. One potential example for your rack would be Pitch to Plaits V/Oct, Gate to a Batumi oscillator Reset/Sync to retrigger it then onto a VCA modulating the Plaits output (using Batumi here since I don't see an envelope generator), and velocity to another VCA to control amplitude. I don't have a Beatstep though so I'm making this up from looking at it. Anyway, you can review the manual here: http://downloads.arturia.com/products/beatstep-pro/manual/BeatStepProManual100_EN.pdf


Just wanted to plug the Mordax DATA. When I was starting out I had a lot of difficulty getting envelopes to work correctly. The DATA helped me immensely in that respect. Being able to see what the waveforms were doing was a game changer for me. It does a lot more than just act as oscilloscope - it's tuner function is also tremendously useful when you want to overdub guitar/bass/tuned instruments or jam with others.

That said, there are other eurorack oscilloscopes, but the DATA is the most feature-packed and useful, imho. For a smaller one, there's this: https://www.perfectcircuit.com/dave-jones-designs-o-tool-plus-oscilloscope.html

I really want a data @baltergeist but they're sold out everywhere :,(


Hi Humanoid01,

I like your case choice, bit pity you planned it already very full. I would like to advice you strongly to keep some blank space for future extension in your rack free, having that said... consider to ditch the Marbles and Alter modules either one of them or both. Once you gain more experience you still can consider them to add later.

Marbles = 18 HP = 7.1% of your total rack capacity
Alter = 16 HP = 6.3%
So these two modules together = 34 HP = 13.5% of your total rack capacity, that's about one-seventh... are you sure that's worth it?

I see that Baltergeist and Troux already answered two of your questions. What I did is I made a rack configuration, shown here below how it could look like with your own comments and that O'Tool Oscilloscope, that one saves some space.

ModularGrid Rack

You still could consider to exchange the 2nd Doepfer A-140 ADSR with another brand's ADSR. There didn't come one to mind to me for your case here but perhaps you could consider an EG from Erica Synths?

That matrix mixer I ditched it and replaced it by the Doepfer A-138p & A-138o combination, this is chainable with just a 2nd 138p and then you get 8 channels; but that's for the future ;-)

I ditch one of your Kinks modules, you had two of them in your rack. Start with one, if you really love that one then get a second unit.

That Bastle Instruments - Cinnamon filter, I don't know it, might be indeed a nice module but it's a nasty one with 5 HP so next to your two chosen Erica Synths - Pico modules, I planned another 3 HP (2+1) blank space for yet another Pico (or other 3 HP) module, so it's nicely filled in again in the future; up to you of course. Instead of the Cinnamon you could consider the Doepfer - A-124 (Wasp filter) or the A-106-5 (SEM filter). I can recommend both, the Wasp filter can provide perhaps a bit more of a sonic adventure, the SEM is a bit more subtle, both are nice filters.

I have a bit lack of time so my rack layout suggestion here might not be ideal but is perhaps an idea of how to get started, the rest is now up to you to plan it the way you like! :-)

Good luck with it, have fun with modular and kind regards, Garfield.


@GarfieldModular wow! Thankyou so much for all of the input and very helpful

I shall have a read up of the modules you have suggested

Thanks to @Baltergeist and @Troux for your feedback too



Quick update question!

What would you think of swapping the Tiptop Audio One sample player with the Disting Ex in this setup? Seems like there are some great functions in there as well as the sampler and prefer it to the MK4 as the menu looks easier to navigate (although of course more expensive).

Also thinking of exchanging one of the Doepfer A140 ADSR with a Joranlogue Contour 1 as again seems to have a lot more functionality?

Lastly was thinking of adding a Pico DSP effects module as it is only 3hp and would be handy whilst I wait for the Folktek (if I still go for it).


Distings are definitely feature-packed, but I find menu-diving on modules to be a pain in the ass. So much so that I'm considering selling my Plonk (well, and the fact that I really don't use it much anymore). Of course, having something like a Disting and setting it and forgetting it seems like a bit of a waste too.... The only module I really tolerate it for is my Ornament and Crime, which I absolutely love.

Personally, I would definitely keep Marbles, I miss it. Also... MATHS. I know, I know, but it, at least for me, truly is a useful module and it looks like you have room. One other suggestion - Folktek stuff is very cool, I've had a few pieces and still have a Nano Garden, but you might be better off with a Chronoblob 2 or something similar. I think they're less hp too. Just some random thoughts.

@baltergeist - interesting - I will check out Chronoblob.

How do you find the Nano garden? Am I right in thinking it is basically an Alter 2 with the mics built in? I am mostly interested in the Alter 2 due to the time stretching capabilities but wonder can you plug external geat through the Nano garden also?


Yes, you can clock/gate it. :)

https://www.alrightdevices.com/product/chronoblob2

Currently, I have the Make Noise Mimeophon and for the most part it's great for what I do. It can also be clocked/gated.

The Nano Garden is okay, but, honestly, I find it more of an art piece/novelty item as opposed to an instrument, and I have a feeling I'll probably sell it at some point. I got really infatuated with his stuff because of the aesthetics, and the Matter ii could generate some great sounds, but I find the build quality a little suspect for the price. For example, the Nano Garden is over $500. I should not have a tight knob/pot, but I do. In addition, the switch for the power supply was non-functional within hours of delivery. For that kind of money, everything should be perfect, and it wasn't. Please don't misunderstand, I'm really not dogging them, it seems like it takes a lot of time to build their pieces and that carries a cost that has to be recouped, and they are definitely beautiful, but the attention to detail might not be at the level of other manufacturers from a functional standpoint. Caveat emptor.

Honestly, I think the same could be said for Ciat-Lonbarde, but for whatever irrational reason I am more forgiving where his work is concerned and I continue to build my C-L collection.

Ok interesting to hear and disappointing as the Folktek stuff looks very cool and actually really enjoyed the videos where they showcase the sounds - particularly where a kalimba was hooked up

Just been looking at the Chronoblob2 and does seem very good but seems in the UK out of stock everywhere! I did also notice the Zzorbs filter Alright Devices have recently released which also sounds very good - quite different to the Jove I have added to my kit but interesting to think that a combo of those modules would free up 8hp for the future. So many choices!


So many choices!

The blessing and curse of eurorack. :)

As for the Folktek pieces, that is merely my personal experience, so take it with a grain of salt.
