Hi, I think at the very least, you will need an output to carry the audio signal out to your system/headphones to get sound.

Maybe something like this for your mixer to go into:

Added Expanded Turing Machine. Beautiful piece of gear. Really a treat for the rig. Also, traded out for an RCD for tripping those clocks. :)

Thanks a lot for the answer. Sorry bother you again but as you notice I'm really lost. Bu t I made many changes.
I put A 135 doepfer for mixer and vca.
I think the system as 2 Rows one for synths sounds (far away the classics analogue) and row 2 for drums and sampler player.

What you think about this? is more consistent:

Thanks again

You're definitely going to have to rethink this. You need some basics such as mixing, VCAs, filtering, etc. You also have too many trigger sequencers.

Hi Guys, My name is Ezequiel I'm from Argentina.
I'm thinking of putting together my first Eurorack system and I need help Because I'm a virgin in Eurorack terms and there are so many options.
I have a lot of Vintage Synth and Drum machines:
Yamaha Cs60, Prophet 5, Juno 106, Arp avatar, MS20, Sh101, Tr909 and Linn drum... so What I'm looking for with this is to find new sounds far away from the classic analog sounds and classical routing of vintage synths and new interfaces to improvise.
This is my first idea for my Eurorack is pretty expensive for my but is OK:

As a rookie in this My question is if I'm forgetting something substantial such as VCA, POWER SUPPY, MIXER, ETC
and also any suggestions are welcome

Thanks a a lot for you help!!

FYI: the active/bypass and active/spillover switches don't work like you think they would-- like you would see on a guitar pedal. the module was intentionally designed this way. Basically: 'bypass' engages the effect. You won't hear delay when in 'active'. Personally, I have no idea why it's this way, but I'm sure someone smarter knows the answer.

Anyone else have problems fitting this dang thing in their cases? I feel like the holes never line up. That's what she said.

TrueGrid MIDI fixed

I think there may be only two people in the world who use this, but for those I can happily report that the TrueGrid MIDI feature is working again!
As a reminder how to get it going:

• it still only works in Google Chrome
• you have to check the Enable Web MIDI API option by typing chrome://flags in your browser address bar
• make sure your MIDI interface is connected and running BEFORE you start the browser
• if in doubt restart the browser
• browse to TrueGrid (MIDI)/Growling MIDI Bass
• select the MIDI port at the bottom of the screen

I had weird fun connecting TrueGrid with my Octatrack...

PS: Have you seen this module?
EURO Brute -- MiniBrute Expander
I have no idea if this actually exists, but it looks cool.
-Ken

Greetings! I am a fellow noob, so don't take anything I say too seriously

I'm assuming you will be playing this from your MicroBrute.

OK, so it looks like you have two basic voices setup, with the standard VCO / VCF / ADSR / VCA. So far, so good. Suggestions:

Add some variety? Perhaps:
* Trade out one of the A-110s for the oh-so-trendy A-110-4 Thru Zero Quadrature VCO (which should be out this year)
* Trade one of the A-147s for a A-143-9 Voltage Controlled Quadrature LFO/VCO (which I think is a great value)
* Add some noise: A-118 Noise / Random

It looks like the MicroBrute has a fairly powerful internal sequencer, but may I suggest adding more sequencer?
* Use the A-118 as your random source.
* Sample gate/pitch from random with A-148 Dual Sample&Hold
* Gate sample drives an A-142-1 Voltage Controlled Decay/Gate for a random-length gate.
* Pitch Sample drives oscillator pitch
* NOOB alert -- I haven't actually done this, so extra glue may be required to get this to work!!!

Housekeeping:
* You probably want to reserve some space for utilities like the A-183-1 Dual Attenuator, or the A-183-2 Offset-Generator
* Even if you use stackable cables, you may still wind up needing a buffered multiple like the A-185-2 Precision CV Adder

There. I've used up all of your rack space, and blown your budget. You're welcome

Just going to request the mixed 5U format feature again! I know you've tried and it's a bit of a PITA - it's just that's how most of us 5U/MU users make up our racks: with a mixture of both.

Cheers, and once again, thanks for such an incredible resource.

The intellijel Metropolis is quite fun to use.
Despite some of the problems i am having as indicated below, it's special programming method allows the user to come up with quite unique sequences.
However, i need to point out three things which i am not too happy about.

The first is the delayed CV output in comparison to the Gate output. This creates problem on some devices and especially with cv/gate-to-midi converters. I wrote to Intellijel about this and here is the reply i got from them.
'On the Metropolis we gave the maximum timing priority to the gate output. e.g. when you trigger it with a clock, the corresponding gate will always fire immediately. There might be a tiny latency with the CV output since it is generated by a DAC and it is slower to write commands to it. We never tested the Metropolis to be used with something like the Doepfer A192-2. In the future we may make a version of the metropolis that has midi. I will have a look at our firmware to see if there is something I can adjust. In the meantime if you have some way to introduce a small delay to the Metropolis gate output then you might be able to solve the problem.'
So i designed a small delay for the gate with a simple attack envelope circuit. That pretty much solves the problem except when a slide is converted to midi. If midi option is implemented internally then maybe intellijel could find a solution for the slide in midi as well. (maybe with the pitch wheel CC)

The second problem is not having the ability to start the sequence from a desired position. You should keep in mind that you have to mess around a bit to come up with something good. I would consider this to be the proper method of programming this sequencer just as it is so for the tb303 as well. The problem is that, when you come up with something nice, the sequence is most of the time shifted meaning it will not be starting from a correct point. Since it is not possible to easily shift a sequence you come up with (after messing around) to start it from the desired point, the only feasible way is to have the sequencer start from a desired position. This could easily be implemented in the firmware. This same problem applied to the original tb-303 firmware as well but if you install the social entropy's quicksilver 303 cpu add-on, you can shift a sequence on the 303 so that it can start from the correct point.

The third problem is the lack of an option for Hz/V output format for note cv. The only way to connect the metropolis to a Hz/V device is with an external V/oct to Hz/V converter. I think this should be implemented in the firmware.

Besides these problems it is a great sequencer.

Here is a link to my 'Portable custom modular sequencer with Intellijel Metropolis'

Also here is a link for my problem and my solution at gearslutz forum 'gate delay as attack envelope circuit'

It doesn't come with any waves installed, you need to sample things into it, or load waves into it with this;

Have not compared it to anything, and I doubt it would sound anything like those. It's an odd one, leaning more towards esoteric than recreating the old wavetable synths. I wouldn't get one expecting it to sound like a PPG, it's quite lo-fi, but pretty cool none the less. Check out this thread for some sound demos;

Have you done any comparisons between the Blacet Miniwave, the Megawave and the Tabula Rasa ??? What's the pros/cons ???

Does it have the PPG wavetables ???

I am very interested in learning synthesis and composing berlin school and psychedelic stuff. I am planning to purchase microbrute very soon to see if I am up to the task. I tried several years ago to enter computer music but I was quickly bored with mouse clicking in front of my monitor. Recently I discovered the re emergence of analogue synths and hoping to jump to modulars if I am successfull in creating soundscapes with microbrute which is considered by many a good entrance to analogue synths for beginners.

I have already been looking to modulars and if money and soul permits I would like to get started with a simple modular rack. Please have a look and give me your thought about alternative modules. Remember I am just starting... At this stage, after microbrute, I wouldn't like to spent more than 1000 euros.

Thank you all and have a great new year!

Here is the rack, I thought would be ok for a beginning.

Hi Guys, looking for advice on my first case. I'm going to be getting the makenoise System 0, and upgrading to the 7 U makenoise CV bus case.

System 0 comes with:
DPO
Maths
Optomix

I'll be using an Elektron Analog Keys for control, and I also have a SEM pro that i'll be using until buy more modules. I want to eventually build a full system primarily for musical sounds as well as more abstract, rhythmic stuff.

This is my loose plan. any advice would be greatly appreciated; looking to avoid any obvious redundancies, and looking for advice on best module placement

thanks!

Attempt at a ribbon controlled monosynth, trautonium style. Lacks the frequency shifter but doepfer don't do one anymore and when they did it was a bit crap iirc.

Oh ... you're the 'Ultima Ratio Cascading Clock' guy! That's an awesome-looking module!

I looked at that one closely, but it seems to function best with an external clock. What do you use for a clock generator?

It works fine as a clock generator, you just loose the ability to control one of the two dividers in clock generator mode.
As an external clock you can nearly throw anything in it, a square wave from an oscillator works best.

I'm trying not to front-load too many obstacles to a successful start-up rack, which is why I'm trying to avoid too much DIY, but I did read through the build document, and it looked reasonable. Maybe not as simple as the Super Warp Generator, but pretty approachable.

Do you still have kits available?

I have a couple left. While the build is pretty easy basic knowledge in soldering can not hurt.
I plan to sell some of them next year as pre-build modules.

@solitud: I have had this debate with myself as well: why program all day for work, then come home and code for fun? I guess there are two (maybe not very good) reasons: 1) my interest in Arduino programming is high right now; 2) I don't expect to be making Music for quite a while (I'll be mostly irritating the wife/friends/dog, especially at the start).

I don't wanna talk you out of it, I am pretty much in the same boat and even developed a module based on Atmega myself.
Modular synth is a hobby that goes way beyond making music for me. The community chats and never ending optimizations of systems are an integral part of it.
You just have to prioritize at one point since time is sparse and you can not do everything.
So if you wanna do your own sequencer, at least make it kick ass.

Thinking of adding the Mutamix. Shifting things around for the new year!

Hello

This is my first rack
I have had quite a few hours experimenting with it.the Mysteron sounds good through the effects

I am however finding it very challenging navigating the controls of the rene

I have read the manual

And watched several videos please send any help in patching and controlling

@mt3: The reason is my perception of the lack of acceptable alternatives at a decent price. Cheap and narrow = inflexible, while wide and complex = expensive, plus hogs too much space on my starter rig. For instance, Grids is an impressive module, but it doesn't offer 1V/Oct out.

Looking at what I do well, maybe my best opportunity to contribute to the community is through code.

I'm unclear with why you need to code up a custom sequencer. And agree with @solitud's comment that it will take away from the music making aspect.
Look into MI's Grids (programmable as well).

I see, some kind of intelligent/macro sequencer. Seems like a lot of work.
While I am generally very interested in microcontroller coding I found out that it is just another distraction from just making music so I try to stick with the modules other people came up with :)
Anyway, best luck with your project!

Thanks for the feedback. The early response on Muffs made notice of that too, so it looks like I will need to add a dual VCA, and probably a mixer.

Regarding a sequencer program, the Euroduino has four outs: two gate/triggers (which I will call D0 and D1), and two 256-value CVs (CV0 and CV1), which I imagine have a kind of stepped output.
So, my initial thought on output mapping is:
* CV0 = Pitch
* CV1 = Rate (the absolute voltage difference from the last pitch)
* D0 = Gate out
* D1 = Trigger out (start of Gate)
Which, from what I've seen, is pretty nice for a basic sequencer.

Now, on to the inputs. The Euroduino has 8: 2 pots (P0 & P1), 2 a/b/c switches (SW0 and SW1), 2 CV ins (IV0 and IV1), and 2 digital ins (ID0 and ID1).
If you think about all the knobs on a typical sequencer, this is a very limited interface. So, one has to make compromises, or be prepared to think differently about how a sequencer should act. I'm not patient enough to program each individual pitch through this interface. The cheat I make is letting the device choose these values for me.

For consistency, I have mostly mapped '0' controls to duration, and '1' to pitch:
My initial thought on the input mapping is:
* SW0 = Duration mode (a=random, b=euclidean, c=darwinian)
* SW1 = Pitch mode (a=random, b=tbd, c=tbd) tbd = some pitch algorithms that sound more organized than random.
* P0 = Duration continuous variable, based on SW1 (a=bit crush,
* P1 = Pitch continuous variable, based on SW0 (a=bit crush, b=tbd, c=tbd)
* IV0 = Either CV for P0, or Spread (duration range)
* IV1 = Either CV for P1 or Center of pitch - roughly a transpose
* ID0 = Clock in
* ID1 = Toggle of mode - repeat or continuous, etc.

This is a rough sketch, but still probably way too much detail than you were expecting.

Basically, I am thinking about a mini sequencer framework, with interchangeable functions for Pitch and Duration.

Any thoughts?

That's in a strange way enjoyable. The track, not your testicle battalion. Glad I have no idea what this means, anyway.

Looks good, but as always, there should be some more VCA?
Interested how you will do the Euroduino sequencer, with only two knobs and 8 sockets ...

All, here is the (mostly final) proposed version of my rack. I'm a noob, so please tell me any oversights or mistakes I might be making.

I wanted a starter system with room to grow, largely composed of well regarded, easy-to-get modules.

Notes:
* It uses Synthrotek's Powered Waterproof 6U + 1U Portable Eurorack Case, with 2 x 84hp of Euro, and 1 x 84hp of tiles. This should provide plenty of power and depth, even for the DuaLFO.
* The Euroduino is supposed to run a custom sequencer that I intend to write (I'm a brand-new wiggler, but a pretty good programmer). The Cloq will provide the basic clocking, and the Euroduino will control the Befaco VC Slew Limiter for constant-time slew between notes.
* I'm most-likely going with the Orgone Accumulator. If so, I will commission it from synthCube. I am not a DIY guy yet.
* Have 2 1U tile Noise sources for really basic percussion, with a simple EG coming from the Strike input of the Optomix.

Questions:
* The oscillator was by far the hardest decision to make. I like the big sound of the Orgone Accumulator, and it seems to work well with a smaller system (a reasonable number of CV ins, and only two outs). The Dixie is primarily there for modulation duties. Any other suggestions?
* Is the Pittsburgh Low Pass Gate a good match for the Accumulator? Or should I go with a traditional filter?
* Should I wait for the PulpLogic 8U 'Magnum' lunchbox case, whenever it comes? (2x euro @ 96HP, 2x tile @ 96HP). It is vaporware, as far as I can tell.

Thanks for your input!

Here is a noodle from over the weekend that I figured would be fun to share..... ENJOY!

Ancient Mind Dwellers,
An innocent journey into HELL

Hello Modulars,

This is my first modular rack. I have a fair amount of CV/Gate gear as well as MIDI to CV/Gate controllers that I want to integrate with it: FutureRetro XS, Sherman Filterbank, SCI Pro One, SCI Prophet 5 w/midi, Moog Minitaur, as well as two Lexicon Primetime Delays with CV/Gate I/O. I intend to use Grids as a drum sequencer with trigger outs going to either an Alesis DM Pro or DDrums module. Can record those as audio and then swap out samples in my DAW (Nuendo/Cubase, using Slate Trigger). I intend to use most of the rack as another synth, basically, and particularly looking to mix oscillators, and also use the Quad LFO for various purposes. I'm new to this....although I'm not really a "noob". I've been an audio engineer and producer for about 15 years, mostly in underground rock and some electronic. Now looking to get more into electronic, but with a pop sensibility.

I'm wondering about adding a few routing modules and maybe a clock module that will hook up the PSU of my Pittsburgh can 90, but will stay outside the main rack and be fit into a half rack space box, along with the Minitaur. There are two power rails and the smaller one should be able to run outside the case. Is this legit? I don't want to take up too much space, as I've got a lot of analog gear.

Any opinions please would be most welcome! Any thoughts on a 4hp module that would be useful in this set up, or possibly a swap out to make space for a larger module that would cover the territory of something currently in the rack? Maybe more routing? I'm cool with using stackables. But there are atleast 3 mixers already in the rack - to juggle in various ways. And also 2-3 VCAs. The Grids trigger outs will just do there own thing, but I'd like to use the LFOs as control.

Thanks!

Video of me playing this patch :

I am pretty envious of this rack

Patch different pitches on ch1 of VM, playing 2 pitches in a series with finger holding on the 1st pad, then the 2nd note would play a 2nd pitch while the 1st hold the original pitch.
