Sure, you might be right with that, but there is a huge difference between the lion and the doepfer 138m. The lion isn't more expensive without a reason. And for his use case the lion is suitable. The doepfer is not (or almost not).

-- MillionJT

@MillionJT - you may be right - I'm just a little skeptical - so I took a look at the spec for the lion (just the description here) and apart from the 'expensive pin matrix' (which is one of the 2 obvious reasons why lion is more expensive, the other being that it's built in Scotland and not China) and the black panel - I really don't see a lot of difference between the 2 - they're both matrix mixers at the end of the day...

it could be that the lion can add a lot of gain, but I don't see that in the specs - and if that's the case you could easily patch say +20db of gain in via Veils or something

so could you please explain why the lion is more suitable as a matrix mixer than the doepfer for no input mixing? or is it just differently suitable (ie the lion has this extra function that you would need another module for)

Utility modules are the dull polish that makes the shiny modules actually shine!!!

sound sources < sound modifiers < modulation sources < utilities


have just watched some videos of the tetrapad and tete combo,defo seems powerfull,could be the way to go for me.

my guess is that if you are asking if you need more utilities, it is because you suspect you do

you seem to have a decent selection of utility modules already - what do you run out of? or wish you had more of?

what do you think you would use most?

what are you reaching for when you are patching, that isn't there?

what can you not do that you want to do with the modules you have?

I was/am doing the techno groove box thing, so here are some notes/concerns...

You have lots of modulation but some of them appear kinda redundant when you take a closer look.
For sequenced modulation, you have three modules(kinda a lot for this size) and two of them are quantized and then a quantizer. I think its important to stay in key, but this is also techno so I think you could remove at least one stepped modulator and the quantizer, or if you really want it, find something that is smaller. Also, consider a small precision adder.

Look also for CV mixers, rectifiers, inverters, etc.... These will really allow you to capitalize on what you have and essential make all new modulations sources. Matrix mixer is also a good shout. Can combine gates, audio, and modulation really useful.

Steppy is fine, but I would check out the Shakamat Four Rooks for perfomablility.
Quad VCA -----> 2020 Veils.

I would also suggest looking into noise sources, Low pass gates, simple oscillators that can be fm'd. Can make for some really unique clamorous percussion.

Hi everyone,

Been filling my diy 6u 62hp for 5 months now but i can't go on much longer ; i definitely need a bigger case asap

I've been assembling a new rack for a few weeks, here's a sketch of it

ModularGrid Rack

I wish i could go a little bigger but i really want to keep it portable and quite light. All the drums are external (TR-8 for now but Octatrack in a month), so the focus is to have a fun 2 voice live playing techno instrument that will be routed to Octatrack for effects and sampling for some tunes maybe, once i get the hang of the Octatrack.

As i said i'm relatively new to this world, coming from Volcas some years ago, to Elektron Digitakt, Minilogue XD, those types of kinda immediate instrument, so i still have this kind of dream of building a more personal and immediate """groovebox""" feel in Eurorack.

So for people playing live on a small rig like this, techno players would be even more helpful, is this making sense to you ?


the instruo lion is a very expensive version of a matrix mixer - there are others that will do the same (less the pegs - that in my case I would loose) for less money - Doepfer do a good one (one of the most ergonomic) and so do AISynthesis

Hi Guys, many thanks for the reply, I really appreciate the time taken. To answer what I wish to do, my influences are very much Tangerine Dream, Tomita, Jarre, Gong, Hawkwind, so while I do like techno, it's not the main intent!

Lugia, I'm blown away by what you've done - lots more research for me to do! that PWRchekr is a new one on me and looks to be compulsory :) And yes, 2 x 104 was the aim for an initial case.


I've read about the no-input approach a while ago but never tried it. But if you searching for Modules who are producing a lot of noise, then take a look at the endorphine Milky Way and the Squawk Dirty. They are notorious for being noisy.

To farkas point. The Bastl Dark Matter does weird stuff and creates feedback loops, but i think it needs an audio source. I guess that is not what you want to do.

One Module who could be interesting is the Instruo Lion.


What about the Bastl Dark Matter? If I remember correctly, that’s sort of the heart of that module but I haven’t looked into it too much.


Sorry if this sounds newbie-ish, but I was wondering if the idea of no input mixing can be exported in Eurorack. Something like having a matrix mixer patched into itself, or just a chain of several VCAs going into each other, or some multiples passing feedback loops between themselves. I love the idea of no input mixing, I'm imagining what sort of coolness would arise by CVing it with control modules or other stuff.
I have a Veils, a Bastl ABC and a Gargoyle Delay and I get some squarewave-like feedback tones if I cross-patch those two, but maybe there are some other modules which have more ground hum that could serve a feedback-oriented approach. Maybe DYIing them would be the answer? Or maybe this just isn't the format for this kind of explorations and I just should go with a regular no input mixer (which would sadden me, alas). If anyone has more information it would be lovely to expand on this idea.


Hi Tom,
working on an hiphop orientated live case myself..
don't mind me asking why go this route instead of getting a MPC for instance?
I am not seeing the extra things what this setup will bring you.
Not a lot of modulation options and besides the per4mer (that I love) not a lot of playability either..

My humble 5cts: get a 6u with some utilities, filter, delay/reverb thingy.. makes is all more versatile plus more fun to play around with in an accessible way.
Got myself a Feedback Modules Squeeze (4hp compressor) to glue the samples together a bit #recommendation

good luck


Maybe i'm totally wrong here, but what is exactly the "difference" between difference and the result of a subtraction? I'm pretty sure the result of a subtraction is called difference.

To this point...
CV1 = 3V, CV2 = 5V, Subtraction = -2V, invert that to get my 2V
I think i would just switch the two voltages, if that is possible in your use case.
CV1 = 5V, CV2 = 3V, Subtraction = 2V

I mean it's always good to know about alternatives, but Maths does all of this without a problem. I wouldn't even bother to use an inverter. A Full-Wave Rectifier makes more sense imho. MI Kinks has one.


Also, here's my proof that I made a shit ton of kick drums in one night.
Merry Christmas
https://drive.google.com/file/d/13MuJ1U8vFCTU1plp015f8KkKTRnE4aqK/view?usp=sharing


This isn't a finished product by any means, just a rough draft

A few nights ago, I was searching for the perfect kick in my sample library, and all of them seemed very generic. So I opened up VCV Rack, and during my fiddling around, I made a kick drum. I was using a sub oscillator, the Erica Synths wavetable VCO, a few envelopes for pitch and wave shaping modulation, some VCAs, and a filter... not bad. I made a pretty solid punchy kick. I hit record and then...
The result ended up with me recording over 1,000 different Kick Drums in one night in Ableton Live!
Doing the math, 4 kicks per bar X 16 bar wav files X 20 different wav files recorded = 1,280 kick drums (TOO MANY FUCKING KICK DRUMS) all with their own transients and lengths so that they're all different from one another. And it wasn't even hard! It took me an hour at the most! Recording, going in and changing a few parameters around, and hitting record again. It was that simple.

So I thought to myself "What if I had a skiff with the soul purpose of recording my own drum sounds?"
I know what your thinking, " Corban, why waste time and money to make a separate skiff just for drum synthesizing when you can have a full case filled with more options and modules that are drum sounds on their own, let alone, do it on your computer like you did in one night?"

The answer is simple: Variety of options, an analog sound, originality, and having a sense of control in my sound.
Allow me to explain...

There's a few things that you wanna modulate when synthesizing a drum.
In this example, lets say I'm making a kick drum.

The Click - A VCO like the Erica Synths Wavetable is perfect for creating those beginning transients in a drum hit that sound organic whether it be a kick, a snare, a hat, or a tom. And with a VERY subtle attack and decay modulation, its the perfect replacement for a standard noise generator for making those clicking transients. It has so many options that you can dial in between using a VCA, or just by itself. So that as the beginning shape of your drum can give you almost unlimited options for how your drum will sound in the sum of it all.

The Punch - The punch (thats what I call it) in a kick drum is the fast pitch modulation of the sine/triangle wave, and like the click, the punch is modulated with a subtle attack/decay ratio to the v/oct. It starts from relatively high, and drops fast to a very low frequency. That's how you get that solid bassy "oof" out of a kick drum. Especially when you throw it through a filter with some drive and tune it right. I chose the STO by Make Noise as that body, and the Polaris as my filter to get rid of some of the higher frequencies I might not need.

The Shape - the shape of your drum can be anywhere from very short and punchy to very long and driven. Having the option to shape your drum in anyway you want seemed very interesting to me. Especially since I like to make house music. The shape of my kick drum needs to fit my track and compliment the rest of the sounds without being too overbearing. I like it somewhere in between short and snappy and long and driven, as if it acts almost as a metronome, while still giving it that driving force to move my body and bob my head. Too long, and it drowns out the sounds. Too short and you cant feel it. I like to make it just right. Just long enough for that thump to hit me and let me know its there while also disappearing as fast as it came.

Having all this control, and all these options plus an analog sound, you don't get that with samples.
You get it with this skiff.
And you can create MANY different percussive sounds. The possibilities are almost endless. I guarantee you will come out with something different EVERY TIME.
You could maybe make something like it, or something that sounds close, but never again can you make that exact same one shot sample that is 100% you. Never in a million years. And that's what's so great about it. Having ONE specific instrument with ONE specific job that can make so many different variations of ONE sound, its nuts.

And, honestly, who the hell has a skiff where its soul purpose is to make hard hitting Kick drums? Nobody. That's who. So... that's why I'm going to do it.


A summer (or precision adder) and an inverter will also do the trick.
A - B = A + (-B)


Dammit...this is making me want to add that "Maths skiff" to the sandbox...pair of Maths + a MISO to feed ALL of the patchables here.

Thanks. I surprised myself with the sound, especially the 'cuckoo' which just sort of emerged from nowhere. I think the cuckoo was Maths end of cycle into FM input of Maths, creating a cuck-ooo two note phrase. Crazy! :)


I messaged Intellijel about it:

Yes the module itself is the same. There were a few revisions of the module that will be displayed on the rear PCB, but the differences are quite minor. For example, the first run would close the VCA at the FOLD output if the FOLD knob was all the way down.

They can all be updated to the latest firmware of 2.04.

My new 16 channel Mackie mixer and JBL monitors arrived and had fun messing about today in new studio space.
I may use another part of the house eventually but these areas are great for folks to come over and jam and with the 16 channel mixer can easily accomodate friends with modular synths. A quick demo

Now it is not a Mozart performance just mess around try the various presets and FX from the new Mackie mixer and JBL monitors. Amazing how loud 5 inch studio monitors can sound!


you could set the bar so low for good that it is almost impossible to be so bad as to warrant not being good enough so get a new module - I forgot to take the trash out - I'm not good enough to deserve a module - I emptied the moldy cheese from the fridge - I am good enough to get the module I want/need etc etc etc> -- JimHowell1970

A fine strategy :)


ModularGrid Rack

First off, I am a complete beginner in building custom Euro rack :).

I'm trying to build a live Eurorack hip hop rig. This will be mostly centred around sampling through the bitbox (or like sampler). I'll talk you through the signal flow. I want samples to be triggered by the Hermod sampler. The 8 tracks of the Hermod will trigger channels on the bit box. I also have an OP-1 which will be USB hosted by the hermod to send additional midi info. The 4 outputs of the bit box can be sent to either the effects (ripples or per4mer) or send to the mixer which will then sum the output.
I also have an Sv-1 black box. I will send this synth midi sequences from the hermod as a synth source and use the 3 SV-1b LFOS as modulation sources.

I am thinking of using the Doepfer A-100 LC3 Low Cost Case - 3U as my case. This will give me 4HP left to add an additional mixer or LFO.

Any thoughts on my mock up Eurorack setup? Am I missing something?

Thanks Guys :)


I read somewhere that the wave folder behaves differently (it doesn't cut out the audio completely, when fully CCW), on the newer model, or something like that. Anyone care to clarify this?

Hello,

Anyone using a korg sq64 with cv/gate?
I am noticing a strange noise on the line when i plug the pitch/gate.

The noise disappears if i enter the control mode on the sq64.

If any of you is using that sequencer i would like to know if you are having the same issue (or potentially know why this is happening)
Thanks in advance,

To add a bit of info,

Looks like the cv into the vco works fine as i can hear the different notes if i play the scale on the keyboard.

Looks like the issue is with the gate not triggering not opening the VCA.

I am starting to think the 540 is somehow broken.
Any idea on out to debug further?

Thanks,

Matteo


Hello Lugia,

Thanks for the help.

Unfortunatly, still not luck.

The only sound i can still hear is the oscillator when i turn up the vca initial level.
If the initial vca level is turned off (or turned up until i can hear the oscillator) i can't get any sounds of it it via external sources.

Is there something broken?

Any ideas?
Thanks a lot in advance,

The Mystic Circuits Ana should do the job, but I want to see if I can solve it with my existing modules. I think what I can do is use Maths subtraction, and then invert negative results. So:
CV1 = 2V, CV2= 1V, Subtraction = 1V
CV1 = 3V, CV2 = 5V, Subtraction = -2V, invert that to get my 2V

FYI, I want to use this with a Theremin. I don't play well enough to play in tune with it but I do not want to just quantize the output either, may as well play keyboard then. So the idea is split the CV out, quantize 1 side of the split and compare that to the unquantized signal. The difference is then used to drive something else. Could be a modulation depth of sorts: hit exactly the right CV on the Theremin, you get the 'pure' note/tone. The more you drift away from the correct pitch the greater the voltage difference, the greater the modulation depth. Until you are far enough away from the quantized pitch to hit another note and then the unquantized voltage is compared to that again.
This will lead to some odd results as most scales will not have equidistant 'gaps' in CVs but the effect could be nice. And hide that I cannot play Theremin to save my life.

I'm a bit surprised this 'get the difference' function is not more common, I think you can use it for various interesting purposes.


Hi Joystick. Even with the new version, you are missing a considerable amount of functions to make this an enjoyable instrument. You don't seem to have a mixer or VCAs included in the new rack... Those are going to be pretty important. Part of the joy of techno is adding and removing pieces, fading sounds in and out. How will you do that in this rack?
If you really want to include all of these large modules, you are going to need to add a third row. You could probably fit a good techno starter rack in 2x84hp, but not with the modules you have chosen. Don't get me wrong, these are all cool, but you need some extra pieces.
You would be wise to listen to Lugia's concerns here. I think you would be frustrated instantly with this configuration.
Have fun and good luck!

Good stuff and I need to keep an eye on those mixing desks that Lugia talked about. Not sure where to locate one here in northern California. I did get some new JBL 5 inch monitors with stands and they sound amazing for a low cost affordable studio speaker. Also have two new desks to assemble for my home studio. At least new house has lots of space for studio gear and no more gun shots or homeless all over the bloody place! Whew such a relief. At least I can record pure modular now. I do need to get some acoustic treatment egg crate stuff to put on the walls to keep the massive echo effect from ruin my video recordings. Maybe setup my camera instead of iphone as well.

Hey, thanks. I actually have a hard time working with Odessa. It's not necessarily a complex oscillator that I understand very well. The HEL expander has made it a bit more accessible, I think.


Dammit...this is making me want to add that "Maths skiff" to the sandbox...pair of Maths + a MISO to feed ALL of the patchables here.


You are looking for an analog logic module! Mystic circuits Ana is my top recommendation.

-- Miszczyk

Save that that's not exactly a "logic" module...it has some very useful functions, however, including multiplication of CV levels. But "logic" for the most part refers to the actual Boolean gates themselves, while this is more akin to an adder/4-quadrant multiplier/discriminator. Definitely does more than the SumDif, but the question then becomes whether or not the OP can fit that into their build by freeing up 4 hp somewhere.

Maybe MG needs another category for "CV Arithmetics"...? It's not exactly "modulation", because these recalculate the CV level instead of imposing a modulation curve on them. And it's not "logic" since there's no status-dependent digital on/off states. Nor is this a "comparator" as such...hm...


Nightmare, actually. This will be VERY difficult to properly control without the right utility modules. And not in the "you just have to get used to it"-difficult way, but more like "I think I'm going to kick this across the studio"-difficult.

For one thing, while it's obvious that the intent here is to create a bass + drum setup, there's problems emerging almost immediately. Take the mixer, for example...it's stereo, sure, but where are the pans? I'm betting you don't want the sounds panned hard-left and hard-right, but that's exactly what's going to happen here. There's also lots of sound sources + the Magneto that can make use of modulation sources...and no modulation sources save for a pair of two-stage EGs.

Then there's the matter of the case itself. Do you REALLY want to cram things into a 2 x 84 hp cab? If you can go larger, I'd strongly suggest doing so. But for the modules, the opposite applies; you need LESS big panels here, as they're crowding out things that should be there.

And then, VCAs...sure, it's a drum-type thing and it would SEEM like VCAs won't be needed...but guess again! You need VCAs for at least your modulation section, so that you have amplitude control over modulation signals. These allow you to get more animation for your sound sources, and having VCAs in your modulation paths lets you go from a tiny wobble to wild swings whenever you wish.

I'd suggest stopping going further with this for now. Instead, get a copy of VCV Rack and get accustomed to why certain modules are essential to ANY build, such as VCAs, attenuverters, submixers, etc etc etc. Also, prowl through other builds on MG that are created by experienced modular users and see how they approach the same technical issues that're present here. Nobody but NObody gets a first build on MG right...but then, this isn't a video game, and no one should EVER "speed-run" building something on this order of complexity. Take the time to study how/why these things work, get some more fluency with what you'd use for that, THEN re-approach this. I guarantee that, if you take the time, the results WILL bear this out.


The Roland 100M dual VCA works a bit like the ARP 2600 VCA: you have to raise the initial level slightly before it'll be reactive with the EG's output. But keep in mind that once you've got that slight "open-up" set, you'll need to really "thump" it with the EG's output into one of the VCA slider inputs. Also, try switching between LIN and EXP to see if things improve; linear response is what you'd normally use for CV and modulation signals, and the exponential response is tailored for audio use.
