Yes and no. First of all, DC coupling only really comes into play when you're trying to send/return CVs, etc to your DAW so that software such as Silent Way, Volta, or CV Tools can directly address the modules. I use a MOTU 828 for this, myself. Expert Sleepers also has an extensive line of modules and expanders that can do this; they're sort of the...well...experts at it.

Now, all that a VCA is going to do is to control a signal's level. Linear ones (with DC coupling) are what's used for CVs and modulation signals, and exponential VCAs (AC coupled, quite often) are used for audio so that the level changes seem correct to our ear, since we perceive apparent loudness in logarithmic changes. So a VCA won't get your signal to the Presonus interface as such.

Now, I'm going to assume you're talking about Intellijel's Quad VCA here...this is a 4-VCA module with variable responses (which makes it useable for ANY signal type) which can also function as a mixer, with some configurability when patching. But again, you can't take the output directly from this and send it to the Presonus, as synthesizer signal levels are considerably hotter than what the interface is wanting to see at its inputs. Instead, the module you need for this is an output module...something that can step the level down from the +/- 10V (at max, as a rule) signals to the +/- 1.4VRMS line level that the Presonus is expecting. So, if you wanted a solution that all four of the Quad VCA's outputs can connect through, something like a Ladik P-520 or a pair of their P-530s would work.

BUT...it's very important to not pass DC in your audio path! DC can do things like wreck speakers and amps when it's present in audio signals and screw up levels and stereo balancing in recording. This was always a big danger with the ARP 2600, for example, since it had a DC-coupled audio path through the entire synth and could output DC offsets along with the audio signal, potentially causing speaker burnout, amp damage, etc. So choosing an output module with a balanced output, such as a Happy Nerding Isolator or an Intellijel OUTS, is important. These contain isolation transformers that output balanced audio on TRS jacks, which the Presonus should also have, and not only do those isolation devices prevent DC passage on to your DAW, they also help kill noise and eliminate ground loops. I always recommend that people use isolated, balanced outs for their output modules.

So if you wanted to pass audio directly from the Quad VCAs individual VCA outs, you would need a pair of those 2-channel isolated types. But if you're using the Quad VCA to mix your audio while it's still in the modular, just one isolated output will suffice. Hope that's somewhat helpful!

Depends on the dual VCF in question. Some of them, like Doepfer's A-106-1 or the Intelljel Morgasmatron, have their basis in the Korg MS-20 Sallen-Key pair. While they have two VCFs, they're more intended to be used in tandem for thruput of a single audio signal but you can always screw around with that bit of architecture. Others like the Erica Dual VCF or Radikal's RT-451 are more like true dual filters with varying degrees of linking capability.

Frankly, I like the MS-20-based ones. That Doepfer, also, has an insert point in its resonance path that has MASSIVE abuse potential, allowing all sorts of things to be patched into the feedback path to majorly screw around with the behavior of the filter(s). Consider what would happen with, say, a monophonic delay line in there...fun!

Beefy VCOs with a twist, hm? OK...try some of these on for size in your build:

Instruo Cs-L, tona, troika
Dove WTF Oscillator
Make Noise STO (yep! good choice), DPO
Pharmasonic Digisound VCDO (I have the original...quite neat...you can step thru the fixed wavetables)
Pittsburgh Lifeforms Primary VCO, Lifeforms Double Helix Oscillator
Erica Black Wavetable VCO
Studio Electronics QUADNIC, GRAINY CLAMPIT
VOID Gravitational Waves (probably the cheapest complex VCO)
Mannequins MANGROVE
Synthesis Technologies E340 Cloud Generator, E350 Morphing Terrarium, E352 Cloud Terrarium
Moseley Cosmopolitan
Intellijel Rubicon II, Shapeshifter
WMD Phase Displacement Oscillator mkII
Harvestman Hertz Donut mkIII, Piston Honda mkIII
Sputnik Dual Oscillator
4ms Spherical Wavetable Navigator
Rossum Trident
Hexinverter Mindphaser
1010 Music Waverazor

Trying to stay under $600 here. But this is a good cross-section of some of the more capable and interesting VCOs out there. You'll notice that some of these are actually not single VCOs, also...there are several dual oscillators (some in Buchla-like "complex" arrangements), a couple of triples, and the six oscillator 4ms module. Another not expensive thing you might add alongside one of these and your existing VCOs would be a Doepfer A-196 PLL module, which is a strange little thing (VCO, filter, phase-lock loop) that can do glitchy, sync-like behavior while tracking the audio of another VCO. See what works!

yes sorry I am confused too :(
so I already have a Presonus 18|10 which I believed is dc coupled.
I am putting together ( first eurorack) a list of modules that I will be needed,
what I am trying to accomplished is to take multiple audio signal output from some of the modules and record it on my DAW
I was wondering if a quad vca could accomplish that.

Hello All,

I was hoping for a few reactions. Any comments about oscillators, experiences with them (good or less good) is welcome. I am looking for one or two more oscillators and appreciate your input to this matter very much.

Thank you very much in advance and kind regards, Garfield.

I wasn't aware about it either, nice indeed, thanks!

If one logs-in at modulargrid.net, from there how to get to that page without using that link?

Hello Marco,

Thank you very much for being so tolerant with me, that's very kind of you.

I almost check every two or three days or so to see if there is any news regarding Ground Control and the Black Sequencer, can't wait for these modules to arrive in the shops and hopefully can test them. I hope either one of them is going to be my main sequencer :-) Let's see...

What can a dual filter do more than two single filters? Naturally depending on which dual filter, you might be able to mix the two filters' output or keep them strictly separated from each other. Not too sure how you meant your question? Or did you meant if it's worth it to have a dual filter? If that's the case, well I guess like oscillators, envelopes, LFOs, you just can't have enough filters, can you? ;-) Perhaps indeed you could replace the filter you have planned now with a dual filter, that might be indeed a good idea. Or take two different filters, so you get two different characteristics in your music.

Kind regards, Garfield.

Hi Martebar,

Ha, ha, sorry, it looks like we used your rack post for other synthesizer stuff discussions ;-)

How is your combination of the just new obtained modules and your 0-coast? Must be good, isn't it? I had now almost two weeks ago the opportunity to test the 0-coast from a good friend in combination with my Eurorack system, oh my, that 0-coast thing is a beauty! I love the sound that comes out of the 0-coast hence I am a bit jealous ;-)

Oh no! Now I also read you got an Octatrack?! I am definitely jealous :-) That same friend I was talking about brought his Octatrack too, also a great device. I feel it's not so self-explanatory and needs quite a bit time to get use to it, but if you are used to it, it’s a serious good device!

Ha, ha, the rules you set for yourself are very heavy ones, I would never be able to comply with any of those ;-)

Regarding “Never a module more than once (just for diversity’s sake)” yes, I fully understand that, I almost made that rule for myself too, still do that actually... just for me there are a few exceptions. I got the Xaoc Devices – Tirana II sequencer, got two of them so I am able to make an 8-step sequencer of it (instead of a 4-step) and I am even considering to get two more to make it a 16-step sequencer, but not sure yet.

For envelopes and oscillators I am willing to let go that rule too. In another post I was mentioning how happy I was with the Erica Synths Black VC EG ADSR, so I am thinking of getting another one. Same goes for the more simple ADSR of Doepfer, i.e. A-140-1.

Regarding oscillators, I can imagine it might come in handy at certain situations to have let’s say two or four the same oscillators, but I haven’t reach that stage yet. I read your comment about oscillators, I also consider the STO, perhaps Godspeed+ (Furthhhhh Generator is nicer I think but huge budget issue there...) and Dixie 2+ might be an idea...

I opened a post for exactly that matter: looking for a good oscillator in the Forum --> Modular Discussions --> Some good VCOs required, however I haven’t got any reply so far. Perhaps I put a little reminder in that post, hoping for some experts to help me there. You might want to follow that post, in case I get a reply there, to look for an additional good oscillator. If you are going to buy the STO, then please let me know how your experience is with that one, I strongly consider that one; but not 100% sure yet.

Enjoy your system, I hope you bought a bit bigger case than you displayed here? Otherwise you might need more space soon ;-)

Thank you and kind regards, Garfield.

That Befaco mixer bugs me...you do know that if you mix the -MIX and +MIX outputs as if they were L - R stereo, you'll get some hellacious stereo mis-phasing issues, right? It looks like this is intended as a final output mixer in the revision, which is why I'm pointing that out. If you're trying to put a stereo mixer in 6 hp, have a look at Happy Nerding's PanMix Jr. instead. Mind you, the Befaco is useful for getting simultaneously normal and inverted signals, but this is something that's better suited to modulation signal mixing, where the normal + inverse outs would actually be far more useful.

This isn't exactly making a lot of sense. On the one hand, you mention the DC-coupling on the Presonus interface as if this might be what you want to control the synth with (via Silent Way/Volta/CV Tools), but then you're also talking about VCA audio outputs. A bit of clarification might help...

Whoops

I forgot to attach a link to the revised skiff plan.

Here it is:

Hey guys

Thanks for all your replies.

It feels like I'm getting closer.

Jim:

They are small, that's true. Although I'm trying to limit myself in terms of skiff size as I'd be looking to travel with it.

As Ronin said the 2hp modules aren't too densely packed and as he has advised I've moved pluck but also moved another to leave more space around the knobs for disting.

As it is at the moment I am toying with the idea to build myself a skiff out of a leather suitcase to accommodate three rows. In which case there would be more space for slightly wider modules.

However for now I am also working with budget constraints. I'd like to have a full system by spring.

For now I have about two thirds of it already and I'm just about to sell: a tides, blinds, ableton push 1 and a couple of my lesser used guitar pedals to get a few of the smaller modules to quickly add utilities and functionality to what I already have.

I have: tides, veils, Rene v2, tempi, yarns, nano rings, plaits, pluck, quadatt2, disting mk4, nebulae v2 and the York modular eg.

About to get: 2hp TM, switch, verb, MI links, make noise function and the mixer.

Cg funk: noted. However I do also own a 0-coast. This already has a: function, contour + more. With that and an extra function in the skiff I pretty much have a maths (more or less).

I built my own skiff and I'll prob keep doing that as that's something I can do and enjoy so making a larger one would only cost me my own time plus the price of rails..

Ronin:

Pluck moved. I've also done away with the passive multiple as I could always get an external one or two.. Like those intellijel ones? That made space for poti as I think you're absolutely right that having one would help with batumi's functionality.. Not having to take it out of the skiff to change settings is worth the little money it costs and the 3hp of rack space.

I expect I will be upgrading my skiff in the next couple of months.

When I'll do that I will prob end up selling on some of the 2hp modules to replace them with wider ones.

It's all work in progress.

On the plus side what I already have is giving me a lot of fun as is.

I made a couple of recordings I'm quite happy with.

As I mentioned previously I have a couple of guitar loop pedals so I have been recording a jam on those then jammed again over the top of it. So in terms of vcos I'll prob just be using a couple at any one time (for now). This works quite well when performing as it naturally forces you to develop an idea in stages then to build another layer over the top.

Thanks for all the super expert input and advice so far. It's great to feel part of a greater community where others like to share their knowledge and generally discuss things in a productive manner

EDITED Sep 19th 2019, 20:33

no one knows ? jus want to know if I can use a quad vca like the mutable veil to output multiple track to my presonus soundcard to daw, thanks !

Thanks Lugia, you are really showing me very good points I never thought about...I will surely consider the 7U case option very carefully, you opened my eyes about it!

Thak also to you Garfield, you don't have to apologize. Every comment I recieve from people more expert than me is extremely valuabe. If I was sure about my choices I wouldn't have posted asking for advice. I actually am keeping my eyes open with much interest about Gronud Control and Black Sequencer! As I said, the sequencer is something I'm still trying to leran more about, so if you have any other advice about it I will surely be glad to hear them!

One more thing. Do you guys think it would worth it to look for a dual filter in order to filter more voices independently?

Hi, this setup looks technically capable, yes, but it also looks like it would be a little bit annoying to actually play it. That nRings and Pluck do not look like much fun to tune IMO. Too many tiny knobs all packed together like that... just consider how hard that's gonna be to do anything once it gets filled in with patch cables.

I think you've got some pretty cool and ambitious ideas, I suggest that you'll be better off just looking at a larger case to start with. One that isn't already packed to the brim with mini-versions of everything.

You'll know you have the right size case when it's just large enough that you'd prefer to have a Maths over a Function in the spot. That's the sweet spot.

Ah yes, the modular news sections is really cool and I've been using it a lot lately.

I'm also adding https://llllllll.co to the list as I think there're pretty interesting posts over there.

The 2HP stuff isn't stuffed in pretty densely. Also, much of it is mostly set-n-forget kind of modules. You might want to move Pluck over one module so that it has a bit more clearance.

Also the Batumi has a 3HP expander called the Poti. It's not too expensive and gives front panel access to portions of the Batumi that can only be accessed via jumpers on the back. If there's 3HP to be found in the rack it might be worth it. Also, why you should have spare rackspace in all of your builds.

Hey Alex

I'd watch out for all the smaller modules you have there - a lot of them are going to be difficult to use unless you have baby fingers

a lot of the 2hp demos videos show them with blind panels between

I find that having a module that has a bit of space around it (say a mutable one) either side is a decent solution - this goes for pretty much anything up to 4hp - disting is really fiddly unless you have space around at least the knobs

Jim

Also, just to keep things Under control and sustainable, I've set myself a few rules:
*Fixed budget every month
*At least make a few tracks with your current module before buying more
*RTFM and read posts on forum to learn all about your modules
*Only buy second hand
*3U only, if the new module doesn't fit, don't buy or sell others
*Never a module more than once (just for diversity's sake)

Thanks again, Lugia! Based on your post, I think I can learn more from the Disting, so I'll start there and swap in the MScale if I find that the tracking issues are giving me grief. You're right about the hp math not working well with the headphone module in there; as I expand the 1U over time I'll keep in mind that I may want to remove it to optimize the row.

I didn't know what an envelope follower was, but reading about them blew my mind as I hadn't really thought much about that application of modular. I may need to dust off the electric guitar down the line.

Oh wow, I was not aware of all these replies, there has been quite a discussion here!

Anyway, I'm happy to say I have finally made the plunge, started my system and this is what I have so far!

Sequencing is done with Ableton and my Octatrack. Having LOTS of fun with Stages which unveils new tricks every day, this is awesome!

The future as I see it:
*I hope to use this at home as a one or two voice sound design synth, and live as two seperate voices with my Octatrack sequencing and managing effects. All drums, ambiance, sub bass will be played on the octatrack too
*I plan on changing the A-190-4 with a Mutant Brain to be able to sequence two voices and get extra CV and gates for modulation
*A Mutable Kinks is on the way to add some randomness and interesting logic/maths operation to my system
*As a second oscillator I am looking at the STO, Dixie 2+, Ts-L or Godspeed+. Trying to figure which one will fit best.
*After that I wonder if an Optomix would be a better choice than the A-106-5 for the second oscillator, it would allow me to mix several outputs and free the quad VCA for other uses
*I am pondering the possibility of buying modular sequencers, I love the many exotic concepts I could have access too, the Marbles seems like an awesome option, but I'm wondering if it will suit my music, and if a combination of smaller more specific modules (2hp's TM, arp, euclid and tune, Tirana II, Noise Eng's Repetitors, etc) would be a better idea

Lots of questions I am hoping to find answers to in the following months, in the meantime, I have lots of music to make.

Cheers everybody and thanks for your help!

Hi,

Last month I purchased a module (through bank transfer, which wasn't clever, seller wouldn't take PayPal), and tracking the package looks like it was sent, arrived in the UK and then was either lost or undeliverable. Royal Mail can't allow me to claim for a lost item until the seller contacts the postal service in their country, but the seller has failed to respond to messages.

Has anyone managed to fix this kind of situation? Best guess, the item is sat at Heathrow with an unreadable or wrong address. It just needs the seller to start the process...

I was not aware of the Esoteric Modulation podcast either! thanks for the suggestion, checking it out now.

I have two more suggestions

https://www.reddit.com/r/eurorack/
https://www.reddit.com/r/modular/

Both are subreddits, but are well worth checking out to see what other people are doing with modular synths.

hello, I am new to eurorack and I am trying to figure out how to be able to record multiple audio voices to my DAW (multitracking) at the same time (at least 4 separates) I have a presonus studio 1810 which I believe is dc coupled. will a quad vca do the trick ?

Hi Wedoh,

Thanks a lot for your help in let me understand the NW1 :-) The Drifting through Space, is that made by you? It's a nice slow, droney one! I still don't get it how you can make it so slow?

Meanwhile I got a bit more out of the NW1, I also followed up on your suggestions, nice results indeed but that real slow output I can't get it, how you manage to do that?

I am using the Erica Synths Octasource outputs for modulating the NW1 (all CVs, currently modulating the Tune, Travel and Position). I get fantastic kind of science fiction sounds (kind of 1980's ;-) ) out of it but not that nice slow movement you can manage to get out of it.

I don't have the Mutable Instruments Clouds though, seems to be discontinued product, do you know if there is any successor module for the Clouds? Can the Clouds make it sounds so slow/droney?

Regarding the Intellijel Springray2, I got the small and the medium tank, both hidden back in my Doepfer low cost casing. The small tank can be at sometimes a bit "rough" :-) Whereby the medium tank is good in case you want to have it a slightly bit subtler. Tonight again let the NW1 run through the Springray2 and indeed that sounds good and thick if you want; lot of ways to configure (using the 6 knobs) the Springray2 from very subtle to not subtle at all :-)

My recording options are a bit limited at the moment. I try not to use my computer, I use it professionally already extensively and that's enough for me, one of the reasons I went for modular! :-) I could record it with the Erica Synths Sample Drum, wav format. Do you know if it's possible to send you a wav file via personal message within this website?

Kind regards, Garfield.

I would keep the MScale. Using a Disting for that one purpose is a waste of the zillions of other useful things that it could be doing. Which, of course, means that you really ought to have a Disting in this for all of those other things. It's a Swiss Army Knife of functions in a very small space, which makes it ideal for smaller builds like this. Besides, the MScale is designed for this specific purpose, and you'd have to prod the Disting into doing what it does in all likelihood.

That Noise Tools tile is also super-useful...lots of function, little space. Plus, consider pulling the headphone module...this opens up space you can use to put a much better MIDI module in. And with the extra 8 hp left, you could drop in a stereo VCA for your overall output level control or for controlling the level on a stereo FX return...or get all pimped out with a pair of USB power ports and a couple of gooseneck lamps on each end of the 1U row! But my bet is on the stereo VCA, as that would fit in with Ronin's idea on processing, above.

One other point about the 1U row: with the inputs, consider adding an envelope follower. This then allows you to extract gate and volume contour CV from an inputted signal, which you'll want if you get the idea to use this as a processor (modular synths can be KILLER processing gear!). There's not an Intellijel-format tile with this, but there's plenty of small 3U ones.

Comparator? Easy-peasy...remove the Black VCA and the A-132-3, and replace them with an Intelljel Quad VCA, which then leaves you 6 hp you didn't have. Then, my suggestion for that 6 hp space would then be SSF's Tool-Box. So as a result of that swap, you now have one more VCA and all of the VCAs would then be variable-response for either audio or CV/mod work as necessary, plus the Tool-Box then gives you a 2-in summing mixer, a rectifier for positive offsetting and/or waveshaping, a comparator, an analog OR (gives the maximum of two inputs...feed it two LFOs and watch the mod curve craziness!), another inverter, and an electronic A-B switch. And all that for only $27 more than the current two modules!

There are ALWAYS solutions. They just require lots of poking at things. ;-)

Hey Diego,

You are welcome :-) And yes, I got the same, I have to click on your rack to see indeed the Pico Mod modules properly; bit weird indeed.

Please keep us updated once you got the system and have played a while with it. Oh man, this rack with your Elektron stuff, that's just fantastic :-)

Well done and kind regards, Garfield.

Thanks, Ronin1973. The M32 does have a noise source in addition to the one VCO, but the 1U module you mention looks like it has a lot more than just noise to offer. Also, thanks for the recommendation on the Mimitec Digitalis. I'm definitely going to eventually want a dedicated sequencer module that's more intuitive to use on the fly than the M32's sequencer.

I definitely plan to take it very slow as I have a lot to learn about these modules before understanding where to go next, but I've seen enough warnings on this site and others to know that is easier said than done.

I had no idea that this Modular News section existed. Thanks!!!

Yeah, I noticed the 80mm depth on the modules’ page and thought it was weird. I haven’t measured the actual depths myself, but the half of the 6U Rackbrute without the bus board is the deepest the case gets, so I’m guessing that 75mm is the maximum depth.

The Rackbrute manual (and the module page on modular grid) seems like it has inconsistencies in general. Pay close attention to the Power Supply section of the manual. It seems like you need to distribute your power between the two rows of pin connectors on the board. This way you don’t overload the power supply.

Maybe someone with more Rackbrute experience can clarify?

EDITED Sep 18th 2019, 19:10

I don't see a noise source on the M32. Maybe I'm overlooking it. But Intellijel makes a 1U sample/hold/slew/clock/noise module. It would be a great addition.

When you're ready to grow: think about effects like reverbs, delays, overdrive/distortion. Also a small clockable sequencer like Mimitec Digitalis would go well for some creative fun. Sequencers are great sources for modulation apart from generating notes.

Take it slow and experiment recklessly. This is a good entry point but you'll probably push the M32 out of the case within 6 months to a year.

Good day Garfield, Lugia and all the rest of the fine people on here !

Indeed, the A-160-2 is a much better option, I changed that and added the A-166 too. Crazy rhythmic patterns, here I come :)

As getting rid of the Doepfer mixer was maybe a little too minimalist, I put the A-138p and A-138o back in the setup. As much as I'd like to add a comparator or another small FX module, looks like by adding the mixer back and the logic module I filled up all the space, I even had to move the Clep Diaz up to get everything to fit in there. Oh God :)

Updated version:

I got an email back form Erica Synths stating that they could maybe offer a discount for a large purchase and I'll see if I can source some modules from the 2nd hand market to reduce costs, but now I feel comfortable about the setup.

I'm repeating myself but I don't care: THANK YOU FOR YOUR HELP ! You guys made my day, for a few days in a row :)

Cheers !
Diego

PS: not sure if you have the same issue: on my machine the Pico MODs are not shown properly in the preview above, gotta click on it to view the rack which shows the modules properly.

Just tried Firefox from my wife's notebook, and, surprise surprise, no problems whatsoever !!
So it's definitely Firefox on my PC that doesn't do what it ought to.
Think I'll have to de-install/re-install it completely. Oh well ....

Thanks anyway, MG!

also, watch your module depths, as the Rackbrutes really only have about 40mm in practicality.
-- Lugia

According to the Arturia website —
The max depth available on a RackBrute 6U is:

53mm on the upper part. (power bus)
75mm on the lower part. (no power bus)

-- Footage

That's so weird. The Rackbrute's own power supply is listed as 80mm Deep..
https://www.modulargrid.net/e/arturia-rackbrute-6u-3u-power

Firefox should work. I have tested it on MacOS and Win10. I haven't heard of others with this problem yet, but maybe they just did not report.

Thanks, Lugia! Any thoughts on the Pico MScale for M32/Dixie pitch tracking? Could I replace with Disting mk4 (which seems to do precision adding and a lot more) instead?

I greatly appreciate this advice. It's given me a lot to think about in terms of future direction and helped relieve some anxiety about the footprint of the M32. For now, it provides some functionality that I don't have in other modules (e.g. MIDI, Sequencer). But it sounds like eventually I should replace with more efficient modules.

Hi Wedoh,

Yeah... Xaoc devices, I have a few modules of them, not the Belgrad and Zadar though but will keep them in mind, especially the Belgrad. Once I listened to your music and sent you my previous message, you motivated me with your music to play around with my NW1 and though I managed to get some interesting and nice sounds out of it, not so nice/beautiful as you manage to do that with the NW1. So thanks a lot for your information, I will have another look at it and see what I can manage to get out of the NW1 :-)

I put the NW1's output through the spring reverb (Stingray2) of Intellijel, also quite nice, missing a delay module though, so I need to look into that.

Kind regards, Garfield.
-- GarfieldModular

Thank you very much Garfield!
I do enjoy the NW-1. Do you have anything recorded that i could listen to with the Stingray? Sounds like an awsome combo!
At first i did not get the NW-1 to work for me. But some twiddling made me found a sweet spot.

This is what ill do
- Change the start position for the wavetable to around 12 o clock, or find a sweetspot
- Set scale to middle
- Change keyboard tracking to like 50%
- Dampen some spectrum and brilliance
- And try out the higher number wavetables, like wavetable "22".

Change prime settings like that and you will notice it starts drifting without any pitch CV or modulation inputs. From there you can do allkind of crazy stuff with modulation. You can play the NW-1 through pitch, noise and simple travel/position modulation, without any pitch CV! :-) And when you run out of wavetables, you can always make your own.

The sound is so rich, so sending it into effect processors really make harmonics going. Something reeeeally cool is to send the NW-1 into Mutable instriments "Clouds". And play with the settings. Make it really drone´y.
Here this Soundcloud link for an example of that.

I have yet to try each of my 31 racks, but the problem definitely occurs on all that I have checked so far (approx. 10).
Just gave Chrome a try and, funnily, it worked like a charm.

I'd like to stay with Firefox, though, for a number of reasons.

Am I the only one with this problem?

ok, I take note.....
but.... not very practical, I must say....
also, not very hard to write that script, no? maybe....
nice day
daniel

Check also the Modular News section here:

https://www.modulargrid.net/e/socialtope/

Currently you can only delete messages one by one.

Does the problem occur with ANY of your racks? If it is a special rack can you send me the link.
Does it work in Chrome/Chromium browser?

First up, don't get used to the idea of the M32 being in the 7U case. It's a lousy idea. It wastes space that needs to be used for modules which don't have a case, for starters. Then if you factor in the cost of rehousing it in the 7U, given that it already has a case + power, your M32 would then wind up costing you about $765, figuring $599 street for it + about $165-ish for the 60 hp it would occupy in the 7U. Not a good deal.

The rest of the modules are actually quite sensible. The Quad VCA is the correct choice, fyi; the ALM Tangle's VCAs are all linear only. It's necessary to have those, but mainly for CVs and modulation signals where you want that response. Exponential VCAs are the ones needed for audio, because of how our ears respond to apparent loudness (logarithmically). By using the Quad VCA, you can select either linear for your CVs and mod signals, OR exponential to control audio levels...or anything in between due to the variable response controls. Besides, the Tangle costs $10 more.

The DixieII+ is actually a decent choice as well. If you plan to feed the M32 through the 7U's audio path, that VCO will serve very well to double the single Moog VCO to allow for detuning and sync and other things that will be pretty useful to getting a "bigger" sound. In fact, I would suggest controlling the DixieII+ from the M32's pitch CV and then feeding its audio back through the M32's VCF and just presuming that it should be a doubling VCO for the M32. While the Mother 32 does have that Moog LP VCF...it only has the one VCO, which means it only has ONE part of the "Moog sound". Using the DixieII+ along with it fixes that issue to a decent extent.

As far as other VCOs/sources...wavetable VCOs aren't a bad idea as long as you can "scan" the wavetables, PPG-style. That's a big aspect of that sound, and one that comes to mind that has that ability is The Harvestman's Piston Honda, now in rev 3. Another route would be a pair of complex VCOs, something akin to the Make Noise DPO or Sputnik's Dual Oscillator; these are more akin to Don Buchla's 200-series oscillators, in which you have ample internal crossmod possibilities that can create loads of possible timbres before ever getting out of the VCO itself! Very convenient! But don't neglect other exotic possibilities as well, such as multi-op FM VCOs, thru-zero FM-capable ones, phase distortion oscillators (ala the Casio CZ series), etc. LOTS of possible directions there, from simple to utterly insane.

But this is coming along...just take this process slowly! It's not a race; consider ideas carefully, ask for advice/ideas, and the like. And don't expect the first build to be THE ONE...because it won't be. There's always room for improvement, along many fronts.

Yep, divider goooood...but choose the more capable A-160-2 instead. This gives you not just the usual suboctave division, but an integer count + divide by primes. Then, by adding a simple Boolean logic module such as Doepfer's A-166, you can combine the outputs from the divider + your regular clock to create more complex crossrhythmic gate patterns. Even better would be to add a comparator to this lineup, which would allow you to track voltage curves coming off of the Maths or the Black Modulator or EG to generate a gate pulse when the voltage crosses a determined level. Put this all together with the logic gates, and the rhythmic timing aspect will be bonkers!

And do put the A-138p and o back in there. The Quadratt is great for summing down the VCOs or attenuverting CVs, but it's not much on audio when compared to a proper stereo performance mixer. It's more of a "utility" mixer, plus offset generator and inverter, while the 138 series is very much audio-specific and allows you to build up a stereo image for your stereo Line Out. By feeding the A-138o to the Black DSP, then going from there to the Line Out and using the DSP's wet/dry knob (or CV control over it) to balance your stereo effects against the dry mix, you'll have loads of control over global effects...and STILL get to use the AUX send/return setup in the A-138p/o combo for something like a mono delay (something simple but with CV, like a Dreadbox White Line Echo) that you can mix in on a per-channel basis. Pretty cool, pretty neat!

But yeah, this is rapidly approaching "button 'er up" time. Think about those last two ideas, then I concur with Garfield...this'll be a damn fine system!

Yeah, the Intellijel 7u x 104 seems spendy...but let's look at it for a moment.

First up, it's powered. And not just powered in a typical way, but with an utterly bonkers amperage capacity: 3A on both 12V rails, 1.5A on the +5. Now, that's serious...it would be rather difficult (but not impossible [although very irresponsible!]) to overload that, even on the inrush at switch-on. A more typical supply in that size of case would give you perhaps half that current capacity. Also, the bus board IS the power supply...this means that you won't tend to have any power components near audio ones in a way that can cause noise/garbage. It also means there's basically NO internal cabling for your DC busses, ergo less to go wrong. See here for more: https://www.perfectcircuit.com/intellijel-tps80w-a.html ...it ain't no joke!

Next, check the construction: all aluminum attache case style, with a lid with enough depth to let you keep a patch in place during transport. Predesigned for a second case to attach, too, via Intellijel's bracket system. But then there's the I/O on this, which gives you MIDI I/O/T + USB MIDI, stereo audio in and out, and your power inlet/switch...all of which is kept off of the patchpanel, meaning more space! And the case comes with the necessary 80W Meanwell "line lump", which simplifies everything...no need to match up the right AC supply for the Intellijel TPS80 supply inside.

So, sure...$649 street. But what you get for that $649 in both hardware AND ease of use...worth it! Also, keep in mind that while you can shuffle modules relatively easily, your case is something you'll be locked into for a while. Get something solid and very capable to start with, and you'll be happy with it for years.

A synth designed to work like a bass guitar. Takes advantage of the surplus of "quad" modules out there. Bass has four strings so we've got four pressure point pads, triggering four envelopes, controlling four VCAs, fed by four Oscillators which are pitched by the four CV converted midi voices. It then runs into a compressor. Because what's a bass without a compressor. Then into a parametric EQ with all the channels running into a make noise panner, so that you can get some interesting harmonic tremolo options.

Hi Diego,

Looks nice! You got yourself a nice system there :-)

There is just one thing left...

Buy it and enjoy it ;-)

Have fun and kind regards, Garfield.

Hi ! Great input here :)

Here we go, v3:

Lugia, you have a point about the price difference for the black modules and I like the idea of using the aluminum panels as dividers.

The 7U case has been on my mind all day to be honest. It just makes more sense, I guess, the 1Us are great to get utility modules on the cheap while freeing up some 3U space down below. In case I want to get crazy in the future, they have a system to mount a second one on top. The case itself is pricier but it seems like it's worth it, so v3 has changed case :)

Intellijel has a 1U tile for headphones. But you'll have to split your stereo signal from your mix to the headphones and your 1U audio input. I think a better choice would be getting a 3U unit that has independent headphone and line outputs with separate control over each and keep the Intellijel in and out for line level gear you want to bring into your system like external reverbs or traditional synths.

1U Audio I/O + 1U heaphones module + 1U buffered mult seems to get me what I want, all in the same space, and I feel like having a 3U line output module and unused line I/O at the back of the case would be sort of weird, right ?

The Mimetic Digitalis has replaced the Vox Digitalis, seems like a better option, thanks for pointing me to it (I had actually watched that video, not sure why I dismissed it). I also added a Clep Diaz, the module seems like a lot of fun (I watched the video only about that module, from Rick Tinez as well). I couldn't resist addind a Lapsus Os too.

I could use the 1U Quadratt as a mixer (and get rid of the Doepfer A-138 modules for now). Not getting me a 1U µMIDI would be folly at that point.

A second Pico Mod is back too, it's cheap enough. I removed the Batumi for now, but a clock divider made its way into the setup, I think it will come in very handy.

How does it look ? :)

I also have the Erica Synth Dual FX. But i don't like it that much. I would prefer a nice delay Module like the 4MS DLD and for Reverb something like the Erbe Verb. Both of these Modules are 20HP. I need more Space.

I've been looking at the Erica Synth Dual FX for a while but it seemed a bit underwhelming. What is your issue with it ?
Yeah, more space, I suppose I'll have that problem too at some point :)

Hi Marco,

I like to appologise to you for my earlier feedback. I can see you definitely had this better planned and looked through than I expected, so please forget my comments regarding that matter. Regarding the 3rd row for space wise you planned but didn't show it, that is a good one :-) That keeps you tight to a 2 rows planning with future possibilities to extend a few modules in your 3rd row.

Good luck with finalising your planning and I hope you enjoy your hopefully soon modular system :-)

Kind regards, Garfield.
