A106? Wow, that's a beast. Is it really worth the space of the 2 other filters? I don't really use HP sounds much, so the LP normalling to the HP is something I'm not sure I am into. The resonance in/out is interesting, I guess you can make it scream if you crank up the CV here.

Here are photos of my prototype build that I did in just 15mins (in thin crappy plywood).

I am realizing a couple things. 1) I need to countersink the metal otherwise my modules won't fit all the way up to the edge. 2) The 1U row only has a single mounting point, so I need to add some bracket or something so it won't spin! 3) It is tempting to just put my modules in this thing already since I don't have room in my other rack.

Edit: Yep, too tempting, I put all the parts together

Next I have to figure out where the power-entry is gonna go, side or back panel. Also need to figure out some kind of flying-bus or something for the 1U modules, as I have more than 20 parts but only 20 headers on the board.

Personally, I'm a fan of Doepfer's A-106-1. It's their take on the Korg MS-20 Sallen-Key filter pair with some extra nastiness (fun on percussives) and an insert point in the resonance path, which opens up all sorts of abuse potential for mangly things by altering the resonance circuit's behavior, either with or without CV control on the altering device. Consider, for example, what sort of trouble you could cause with just a little mono delay line in that path...

Don't worry about it...pretty much no one gets a build right on their first attempt. There's always ways to tweak and improve. My suggestion would be to spend some time looking at builds done by experienced synthesists on here, as well as studying what makes classic synths such as the ARP 2600, Minimoog, etc the classics they are in terms of module complement, control layout, and the like. Like anything worth doing, doing this takes time and patience.

Much of what's needed is there, but you'll have to cut the Braids and Clouds out, since both of them are discontinued. Unless you already have them, you'd either have to locate used ones (good luck!) or use a third-party build of these, in which case the panel layout won't exactly be like this. Also, the SILTA power supplies are a bit of overkill in terms of price and size for what you get with them. A 4ms Row Power 40, for example, takes up 2 hp less, gives you a bit more amperage on the +12 rail, and is a tad cheaper. Or, better still, opt for a powered case such as one by Doepfer, Erica, et al and see if you can get even better amperage numbers with zero hp used.

Seems fairly on point. I take it you'll be clocking the entire thing off the Tempi, using the logic and other pulse sources to set up variations for the Pulsar23? Anyway, the only thing that's a bit bothersome is the layout; I suggest trying to group functions with like functions (VCOs near sequencer/quantizing, processing near the end of the chain, etc) so that the interconnection between this and the Pulsar23 isn't quite as tangly and difficult.

If you want to stick with two rows, have a peek at Erica's 126 hp deep cases...Perfect Circuit has those in the USA. Great price for the size, nice hefty power supply, and major depth, even above the power supply. But yeah, I get the idea now...sort of a modular synth take on an old blown-up Supro amp sound, sort of Howling Wolf-esque.

Yay, my rails arrived from Clicks and Clocks, and I have to say that they just look super excellent. I will post photos very soon.

Now that the parts are here, I can finally start to measure wood and start to make cuts! I had to wait for the rails to make the design exactly to the right size.

In the meantime, I've been rearranging my modules a bit... and it seems like a smart idea to make at least the top row of this box a little bit deeper than initially planned, enough for 60mm modules. The newest re-arrangement has me swapping the precision adder for a dual-quantizer (it can transpose, which is what I wanted it for). I'll just have to fine-tune an attenuverter to 1V with the OTool if I need to do octaves (does that work well enough??)...

Also, I've changed my mind on Three Sisters (seems to weird), and decided maybe the Polivoks + LxD is more to my taste. I went with the Harvestman version because it has a mixer going on in addition. Any thoughts on filters to pair with BIA and the new Lifeforms?

Okay thank your for you reply! So I guess something like this wont turn out to be very playable. Thanks! Guess thats back to the drawing board. :)

Good trade with @Tox.ine
@bobje was the seller, @Tox.ine was the buyer
thanks!

Please see mine and give some suggestions!

Any opinions much appreciated ☺

Thanks Lugia,

I'm going for an aggressive edge to Blues/Rock.
The terminology "noise/industrial-type stuff" scared me a bit, but I've been listening to some music with that tag and, yeah...A nudge in that direction is what I'm looking for.
If I can't tame the Cosmic noise I'll pull it and go more conventional.

The quadrature VCO/LFO you suggest sounds like a good idea, I'll contemplate it.
Might need another row.

Take care,
Burousu

I can see that working for noise/industrial-type stuff, yeah. Although, my instinct would be to eliminate one of the Optomixes in favor of a proper VCO so you can get good audio-frequency modulation. In fact, one pops into mind immediately: Doepfer's A-143-9...quadrature VCO/LFO. That way, you get AF...but you can also switch it down to LFO range and make big use of the quadrature-phased outputs on the VCAs, O&C, etc.

Well, first up, you get 16 hp back since Clouds is discontinued.

The problem with these sorts of builds is that they just don't work out in small cabs. And that gets back to the 'start too big' idea: if you start off with an improbably huge case, you wind up realizing that, hey, it wasn't improbably huge. That strategy works for all builds, actually; start too large, then pare things down to workability (on your own terms...'workable' differs from user to user) gradually until you get to a result. Also, first builds on MG always turn out in the 'WTF?' zone, as far as a usable instrument is concerned. MG is perfect for this, tho...it's a great place to make mistakes, because they're not costly ones. Screw up? Just delete and restart. Try that with actual hardware; it's very spendy and totally frustrating.

Hello ,
What do you make of this as a stand alone instrument?
The "Cosmic Noise" is basically two Jupiter Storm's.
It's going in Doepfer A-100G6 Rackmountable Eurorack Case with Power Supply.
I want it to work with or without a controller/keyboard, but I have an old Arturia KeyLab 49 that will likely be hooked up most of the time.

Awesome gear, now I understand what sounds I have been hearing :D

(please click on the link since its not loading the whole rack)

Hello everyone.

So I want to dive deeper into the world of modular and get myself my first eurorack system. Im reading loads of articels and watching hours of youtube videos. This is what I came up with so far. The Idea behind this rack is that it functions as a hybrid. Bottom row is a synth voice and sequencer. Middle row is dedicated to drum sounds. Top row is in/out and effects.

But I'm not sure if this is even feasible. For instance, I believe that with the current system, I'm not able to output all of the sounds. I feel like there are more outputs or mixers missing. Please let me know your thoughts and suggestions. Your help is very much appreciated!

Cheers!

Hmmm... could have sworn I replied to you...

Anyway, thanks so much for looking over this dream system of mine I hope to slowly build out. I definitely want some "controlled randomness". I thought I was achieving that well enough with the Varigate 8+'s probablistic capabilities and the Metroplis' clock divider and shuffle capability. I'll have to look up stochastic skipper and some of these delay capabilities, they sound great. I'll probably drop the eloquencer; I don't think it's adding too much for its footprint and would be definitely the last one I'd buy.

BTW, one goal is to build this over time and have sound options, not using all at all times (even the sequencers). I have some semimoduler synths already, so thought percussion may be the way to go for me..

Anyway, thanks again Lugia for looking this over and dropping in some hints; this noob appeciates it!

Cheers,
Paul

Oh, yeah...that little DIRT filter is a sneak weapon. I've actually encountered it in real life, but you managed to hit the most excellent 'sour spots' in its behavior and bring out the industrial/acid-type nastiness that it does sooooo well!

EDITED Jul 23rd 2018, 00:50

Except...while there's a lot of different drum voices, I get the feeling you're neglecting the timing aspects. For instance, I see nothing in the way of gate/trig dividers and/or multipliers, or other clock manipulators (pulse counters, stochastic skippers, clock delays). And with all of that, you'd also need a nice bit of logic to allow conditional gate/trigger variation. It's ok if you just want the output from the sequencers 'straight', but aside of the one Euclidean sequencer there, this is lacking in ways to 'humanize' the rhythm feel and/or create controllable variation. Take a long stroll through the 'clock modulators' section here and get a feel for what all of that category's about, and then do the same with the 'logic' section, then give it another try. You may find that the real trick here is less sound generation and more sequential/timing complexity.

Also, you'll want audio delays. I can't even count the times I've used different delay-based strategies to generate hocket-like behavior to make rhythm patterns more complex.

Yeah, it really does sound like it’s folding waves now and then. Not just distorting them.

The idea is to pair this with the Pulsar 23 (when it releases) and an Eventide Space pedal. I feel like it looks pretty good, and more importantly a lot of fun. But my theorizing has proved less than accurate before...

EDITED Jul 22nd 2018, 20:21

The idea here is to have many different modules and sequencer arrangements along with some effects to act as a super sophisticated drum machine.

Sweet dude thanks!! I can’t wait to try it out!

Pretty much! The only thing I'd move is the Erbe-verb, putting it between the Quad VCA and the outputs. That way, you can take the mix out of the Quad VCA and feed that directly to the Erbe-verb's mono in, and stereo out from that goes to the HN output. So you can use the Erbe-verb not only as a reverb, but as a 'stereoizing' module as well. Toss in a couple of multiples for the open space remaining, and that's got that build nailed.

Ill take a look at it! Thank you for the help dude, its great to have some input! One last question! As far as flow goes is everything in order? I fixed it with what you recommended. https://cdn.modulargrid.net/img/racks/modulargrid_705567.jpg?1532093766

Happy Nerding has a couple of nice ones, actually...their Isolator not only gives you a final stereo level trim plus transformer-balanced 1/4" outs, it has ground-lift switches per channel so that you can eliminate any sort of ground-loop hum with a switch-flip should that occur. That feature alone, especially if you play any live gigs and DI the modular into some random club PA, is very worthwhile!

Thank you so much for the response! I’ll definitely keep that in mind! What stereo output module would you recommend?

Not bad...mind you, Clouds is discontinued, but third-party builds can still be had. I'd also swap the uVCA for a Quad VCA, because more VCAs are useful. And some sort of stereo mixer into a proper stereo output module, and that'd do it. Maybe a passive mult if there's room, but if not, just use some in-line mults.

One last riff on the Clouds: maybe this would be a good swap: https://www.modulargrid.net/e/mordax-gxn- ...2 hp more, but it samples and mangles too, but with a lot more interface capability.

https://cdn.modulargrid.net/img/racks/modulargrid_705567.jpg

I was thinking of starting off with a moog mother 32. If not I was thinking of starting off with a SV-1. Do I have everything necessary to get started? What do I need/what would you suggest to get started? And is the flow good or can it be rearranged. Thank you and I look forward to the responses!

Noise Reap's doing some really interesting, deviant design work. Not only is their stuff cheap, but it's quite weird as well. The uBermuda VCO's another bizarro device, with its internal self-regeneration behavior and so forth. They're doing things people need to pay attention to...

2:45 -- OW! It's a waveshaper in filter's clothing!

Is there a crazier filter?

Still looking, if anyone has one to sell.

Hello,

Where can i get this Modules?

Thanks

Awesome post! Love the cv delay idea!

Another suggestion: https://www.modulargrid.net/e/emw-arcade-noise

Get yer Atari 2600 jones on!

give me that gameboy feel

i just love midi

Digitakt is the sequencer, octatrack is the effects processor./
also ableton you get it...

Hola,
This has reared its ugly head again with Sapel.
Someone posted this dupe https://www.modulargrid.net/e/frap-tools-sapel--

I made a boob’s demo video of the DIRT Filter.

I reveived my Radio Music this morning from @toneburst
good job (assembled module), communication and efficiency, maybe why not 5/5!
from a belgian sound maker.............

Could a "19" rack" category be added to the already listed Buchla, Frac etc. categories ?
I need some visual feedback on how to mount those genuine dust collectors/electric heaters units and am tired using PowerPoint for this. I think it's not THAT off-topic as it's always handy to have listed items and easy access to it (no "Reason" pun intended ?) precisely when there is already a "500 Series" one listed.

Your site rock anyway.
Thanks @modulargrid ! :)

Quick shipping of Basimilus Iteritas bought from @Elephantmat, recommended.

Any possibilities to have a poor traders thread? I had an incident where a guy from this forum sold me genuine Mutable Instruments Peaks but the module I received was a clone (verified this from Mutable instruments and they said it looked like a factory made clone, so most probably there are more clone units than the one I have).

The user who sold the module won't respond my messages anymore. Would like to warn everyone else as he seem to be selling a lot.

I haven't had any issues with cables being so loose that they fall out. It could be down to the brand of cables and possibly the weight of the cables and angle of the module. That rape joke is totally not cool though...

In order to get all the in/outs when used as a plugin you have to use Reaktor as an effect and not as an instrument. Hope that helps!

This could also be a bad jack in combination with grounding issues. To help troubleshoot, when the humming starts, try touching a wire to the lip of the jack at each end of the cable at the same time and see if the humming goes away. Also, does additional wiggling of the cable ever stop the humming?

That sounds like a ground loop, actually. Do you know if the powered speakers are on the same AC ground line as the synth, or whether they're grounded at all? If not, that would explain quite a bit.

Probably the best thing you can do is to take the time (and hookup wire) necessary to set up a star-ground to get all of the equipment on the same ground plane. It's time-consuming, but very worth it in terms of cleaning up noise and hum, and might only be necessary for a few pieces of your gear. Have a look at https://www.sweetwater.com/insync/star-ground/ for a very basic explanation of what needs doing...and as I noted, if you can do this only with certain offending devices to clear up the ground loop issues, that works just fine as well.

Here's a couple of feature requests regarding power.
- would be helpfull to have the 'manufacturer Approved' tag also in the datasheet
- it would also be helpfull where you show the total power consumption of a rack to add 'x of y Manufacturer Approved'
