How I use my sequential switch - a-151

2-4 sources -> inputs
output -> input on a module

or

outputs -> 2-4 inputs
source -> input

trigger into trigger in to step through them

sources and destination can be pretty much anything - audio of cv, as the a-151 is effectively passive (yes I know it draws a bit of current, but the switchng is passive, I've also had it switching video

switch cab be set to 2.3 or 4 - gaps in i/o are fine

If you really dig the way that the Furrthrr sounds, then why not go for the original? You could get THREE of Buchla/Tiptop's 258t complex oscillators for a fraction of the Furrthrr and still have money left for a very good bottle of whisky to sip on whilst pondering the spectral mayhem. And if you just go with two and then find another 6 hp nearby...maybe tossing the Super Sawtor (it IS discontinued, after all) to get that...those two 258ts will slip right into place.

Actually, just use inline mult widgets. This build is right on the edge where I would say to not have the mults in a build at all due to space constraints.

Most of the time, a sequential switch is what you'd use to switch between sequencer rows (such as the Moog 960 and the 962) by sending end-of-row signals to the switch so that the next row is, say, row 2 or 3, then back around to row 1, etc.

However, they DON'T have to be used for only sequencing. The ARP 2500's Mixsequencer is an electronic switch-type device that can scan across several incoming audio signals and change the inputted signal each time your clock sends a pulse to the Mixsequencer. But you can do the same thing with most any present-day switch; feed four audio signals into the switch's inputs, set up your clocking for it, and then send the output to whatever audio destination you like. Same thing works with control signals, too.

In the test gear world, these devices are referred to as "multiplexers"...several signals go in, clock steps through the inputs, and the result is a single output consisting of whichever channel is selected by the multiplexer. Same idea applies here, also. One that could be fun is to send differently-divided clock signals that can then cause a sequencer to jump around in time with the switch's selected input. LOADS of that good ol' "abuse potential" there...

Filter? Well, if you're in a situation where the build's only got room for one, this is probably the one you're looking for: https://www.modulargrid.net/e/tiptop-audio-forbidden-planet .

It's a clone of the Steiner-Parker Synthacon's multimode filter. And take it from someone who had a Synthacon for a number of years: if you can only have ONE VCF in your system, this is one to have. Bass ranges pound via the LP input, and the bandpass and HP inputs are capable of yowling leads that will cut through most anything. And it's cheap, too...$120. Fits right in that 8 hp hole.

or start hanging cases on the wall!

Making my own Kick in this from Befaco Even VCO sine and Patching Panda Punch.

The new toy in the mix is the SSF Vortices Mixer, so there are a couple of LFO panned mono parts, the bass line is panned before going into Mimeophon and and a sort of acid blip from the Frequency Central Boing!

Bigger house!

Wow, what a monster. So, this is where the buy a bigger case mentality leads...

-- Vow3ll

hahaha, no it's where DIY and video modular leads... I've only ever bought 2 cases & I often think that if I'd been able to buy a mantis first and been able to add Maths to the modules I first bought, without buying that second case, that I'd've been able to stop there... but who knows and who cares - I certainly don't

Hi everyone,

As I am sure all of you know, Ukraine is currently undergoing an unprecedented brutal attack and facing a terrifying threat of Russian occupation, with nuclear threats already made. Many of us are also no doubt familiar with brilliant Eurorack module manufacturers from Ukraine such as Happy Nerding, Knob Farm and Endorphin.es whose families we can assume are at grave risk. There is already a lot of support from the modular scene, for instance the manufacturer Erica Synths is currently donating all income of certain modules to charity for Ukraine, and there is an initiative from ambient artist and YouTuber Hainbach who has released a single with all profits going to the Red Cross for Ukraine.

Inspired by these initiatives, I propose that we can also use ModularGrid to raise funds for Ukraine. I've personally put up a number of modules on the marketplace of which I will donate all money to the Ukrainian Red Cross. If more people join this, we could even opt to create racks in which we add Ukraine Fundraising to the name so that we can use the search function to buy the modules we are looking for, while being sure that profits of our purchases will go to humanitarian aid. I hope this act of solidarity does not go against the user policy of ModularGrid.

A list of trusted causes can be found at https://tinyurl.com/HELPUKR

With hopes for peace,
Rik

bigger desk?

No space for that, I'm afraid. I already have two 6Us attached together. I literally have about 10 inches of desk between the Brutes and the PC monitor!

Just for reference, this is the Rack. The two Fansynths don't exist but I'm holding space for them (or something like them, Mutant Modular told me something better is on the way) because this thing gets hot and I'd like my modules to last well into retirement...! I use the rack for generative stuff.

EDITED Feb 28th 2022, 14:17

don't waste money on small cases - yet - just get another 6u rackbrute - or better yet sell the rackbrute and buy a couple of mantis (when you can)

Thanks for the module recos but I think in my case I don't anticipate bringing in signals that much – famous last words in modular, haha. I don't play other instruments, don't have loads of guitars laying around etc. The Sonicsmith looks really good, with all of the extra things it can do.

So with that in mind, I'm thinking about getting a very small and deep (so maybe custom) case for the ES-9 and something like the Sonicsmith - to free up a little HP in the RackBrute and take a bit of load off its power consumption (that ES-9 is a beast). I live in Brooklyn so space is an issue and it all has to fit on my desk!

Yeah, I stand by my original suggestion. Get the 208hp case, add some of the modules that you really want, and cover the rest with blind panels until you know what you need. Plan long-term and add modules as need and budget dictate. This is modular after all so you can always take a modular approach to the rack itself if you plan right. I started with a plan of 416hp (i.e. two Mantis cases joined with brackets) and my initial investment was 104hp worth of modules. I then began adding additional support modules when I could. I now have double my original plan. Modular is my main instrument, so that may be overkill for many users, but it works for me.
Buy the modules that will give you the most joy and inspiration. Don't just buy what is small, available, and affordable in the present. You are building a highly personal instrument that could last decades, so build exactly what you want. Don't get me wrong, I've purchased some modules that were duds just because I wanted something (anything?) new, but for the most part I've stuck to my long-term plan. And your long-term plans will slowly shift as you begin adding modules and realizing that your preferences and approach to sound and workflow differ from the capabilities and styles of some module manufacturers.
Above all, have fun with it. Don't go into debt. :)

Edit: Here's my current rack if you are interested. Again, I started with 104hp of modules (some of which I still have in there). Just be sure to cover open spaces to avoid screws and patch cable tips from touching any power headers.

@Broken-Form

outputs to modulation inputs on other modules

adjust attenuverters to set ranges

turn knob (or use input - use attenuator as needed) to change value at output...

imagine the attenuverter for output 1 is set to about 9 o'clock - roughly -0.5

as you move the knob from fully counter clockwise (0) to fully clockwise (1), the value of output 1 will move from 0-> -0.5

etc etc
-- JimHowell1970

Thanks will try this out today

yeah this one looks vaguely correct
upside down stuff is diy backlog - I'm pretty sure that some is missing (probably 3 or 4 DIY video modules) - or in the case of chromagnon - pre-ordered about 2 years ago...

but I don't think it's going to help you...

there are 8 cases in total - 2 * 9u / 104hp, 2 * 9u /84hp, 2 * 6u / 84hp, 1 * 6u / 72hp, 1 * 6u / 104hp (mantis)

and just at the moment - it's all over the place - cos I'm playing with 3 cases in the living room...

maybe ya right.... maybe a mid size case...

its so confusing ...

have you got any of your case Modulargrid i can look at..?

EDITED Feb 27th 2023, 07:07

I'd definitely try working out how to use the black sequencer properly 1st...

you can do a lot in terms of clock division and turning gates on and off per channel - so a single clock source into the black sequencer - or using the internal clock - doesn't mean you are playing all 4 channels at the same speed - they will be at related speeds - and euclidean rhythms won't work - very well - but you have another sequencer anyway... it's nice to bounce a euclidean sequence of a non-euclidean one

matrix mixer: difficult to tell as there are a lot of black patch cables - but I suspect he's taking the 2 sequencers which are running at different speeds and mixing them together in different proportions - before sending to vcos, probably via quantizers

EDITED Feb 28th 2022, 05:09

hmm - well it's your money! personally that doesn't work for me - having no money means I spend less money - not no space left in cases... I've got at least 300hp free space in my cases - blind panels and panels for diy backlog...

the rack:
too many sound sources in too small a case
ergonomic nightmare:- too many small modules together - disting is a pita with modules that have knobs or jack near the knobs, switch needs to move so that it's at an edge, for the same reason... filter knobs look unusable etc etc etc
steppy and pams - would lose steppy for noise tools if possible...
fx aid and the intellijel - probably wouldn't pick both in a tiny case...

how are you intending to sequence pitch???

hope this helps!

H Jim,

I know what you mean, but im trying to be conservative for now...
if i lock my self to a smaller space I'm less likely to splurge on more gear..

im trying to have bits of things that i can still experiment with. plus these could be great units in a future set up.
(long in the distance future).... HA HA HA..!!

what do you think of the new layout.. ??
after a lot or reading & watching reviews i think i could make some interesting grooves
plus i still have other outboard gear.

Cheers

Yeah I think if that's what you want to do your best bet may be to sell the Black Sequencer and get something like the TipTop Z8000 instead. You may lose certain features but you'll then have multiple sequencers in one module and you may also come away with a few $ in the transaction.
-- adaris

Thanks so much for the tip on the sequencer. I’ll definitely check it out. In the meantime, I’ll add in my Dark Time to see what I can do. Do you by any chance know how he’s using that Matrix Mixer?

I think this is a very short term solution - so I'd still get the bigger case - yes it's going to cost a bit more - BUT - if you are like most people you will want more as soon as you can afford it - and this way you are prepared...

remember you don't need to fill the case immediately or ever, for that matter - blind panels are your friend...

@Broken-Form

4 modulation sources -> 4 inputs of seq switch
output of sequential switch -> modulation input of some module
some trigger source -> switch input

1 modulation source -> input of sequential switch
outputs of seq switch -> 4 different modulation inputs
some trigger source -> switch input

2 sequencers -> 2 inputs of seq switch
output of seq switch -> vco pitch input
some trigger source (possibly last or first step from one of the sequencers) -> switch input

remember to switch no of steps in the seq switch 2,3,4

remember that switch is bi-directional - inputs become outputs and vice versa depending on how it's patched

examples refer to the doepfer a-151 - but may also apply equally to other sequential switches

Hey peeps,

after some great advice for JimHowell197o & farkas, on scaling back my ambition on case with 208HP of modules ..

A) cost..
B) getting to know a smaller amount of gear better ..

that all made sense it the light of day..
so I've scaled to a Intellijel Palette Case 62 HP
note: the very top 1U line is what comes with the case.

i welcome feedback & ideas ..

Cheers

Another vote for the Livestock Electronics Maze, I got it yesterday for my new build - it's powerful for 12HP and I really like it.

-- Vow3ll

Right on! I love mine and create presets that let me do transitions and fade in/out cv control on my system. My other modular has 4ms VCA Matrix which is great module as well. Most of recent modules have been to beef up my support utility toolkit.

I have the A1 synthesis matrix mixer.but need to figure out good ways to use it

I also have the FSS Makrow.but havent used it yet.as im abit baffled how i should patch it up.and there really isent any videos about it.

Thanks for the input Lugia.
I think I will part with the Furthrrr generator and get maybe 2 smaller VCOs for this setup.
The thing with the Queen of Pentacles is that I really fell in love with that kick drum and the hole module as per say . I was considering an external drum machine like the RD-9s but I would like to have all these things in my case. And so for the Ground Control as well, I really like it the workflow and then how it incorporates with the Queen of Pentacles.
For the Instruo Arbhar my idea is to make textures to keep the mood of the track in the back ground running.
I would say these tree modules is my main aspects of the idea of Techno case I would like to build.

For the utilities modules what should I be looking at more to make this integrate well with the concept?

Thanks so much for the input, much appreciated

I decideret to sell my hermod and the CV sequencer. Got a plaits.and a sequential switch adder to my system.for sub i have a sub101 duo coming from analog lab swiss.

So for now i use my korg sq1 with plaits.

One Thing im abit unsure about and havent wrapped my head around (need to watch some tutorials)is maybe getting rid of gran terminal and the expander.think its a Hard module to figure out.and maybe get something like erbeverb. Desmodus fx aid xl instead.
Also need to figure out a good way to use PNW in my system.

Can anyone give me some pointers in ways to patch the sequential switch ?

It's worth mentioning for posterity and because we here love chaos, that the Batumi echoey firmware implements what is called "Verhulst's logistics map" . Since Batumi vanilla is just regular LFO this may not be obvious but it is a pretty useful implemtation such that you can have the four generators running independent or phased versions of the chaos and will have corresponding frequency synced sin and square waves not to mention self modulating possibilities for frequency modulation of each generator. 😎

Could you post a video clips of this?

So, here is version 3:

Very basic setup with v/oct coming from the BSP to the oscillators and triggers from BSP to Zadar. Then a couple of effects and modulations. I replaced one of the bOSC with a Plaits for more flexibility.

You get 4 channels of Pre-amp in this https://www.modulargrid.net/e/making-sound-machines-tausend-db

I recently picked up a Blue Lantern Booster Array which has 8 separate preamps in 10hp for under $100. I’m using it with the individual outs of a drum machine but it’s great with other line level gear too. Works perfectly. Highly recommended. I think it might be a limited run, but there were a few still available on Reverb last time I checked.
Have fun!

Well, check my latest post above. I get the what and why of what's needed here, I'm simply offering options so that it's more apparent that there's solutions OUTSIDE of the DAW environment, as well as VST solutions within it.

I must have missed that one. I know the TC Clarity quite well - I have several units at work where we use it for sound normalisation to EBU R 128 for TV broadcast. It's overkill for what I have in mind at the moment, but thanks for the suggestion. If I feel the need to upgrade, I will definitely consider it.

Hello friends.

If you would be so kind as to take a look at this horror I've been cooking up and judge me:

My lack of filters is where I'm hoping most of my mistakes are, and that you can help solve this!

Thank you for your time and patience from myself and all fellow newbs who post their mistakes here.

Hi all,

Following up on the advice I received from the previous post (https://www.modulargrid.net/e/forum/posts/index/11058). Is this new version nearer the mark? I tried to keep @JimHowell1970 's formula in mind this time. Is this distribution of modulators and utilities more reasonable? Any feedback or suggestions would be welcome!

Thanks!

I don't have any experience with either the Dot or the Black Sequencer, so take this with a grain of salt, but it looks there is just the one clock input on the sequencer, and the channels all run off of divisions or multiplications of that same master clock, so I'm not seeing how you can use two separate channels from the dot to advance channels 1 & 2 separately.
-- adaris

I see. That makes sense. Honestly, don’t laugh, on top of being a noob, I can be dumb, too lol. …but is there a way to like split a clock signal or whatever so that we could somehow work around this? Or would you suggest a secondary sequencer to do what I’m trying to do?

This is basically what I want to do. I do notice he’s using two sequencers together.

Hi there,

So I’m building a somewhat basic setup with my Behringer neutron. I have doepfer A-180-2 Mult, a Doepfer A-138 mixer, Dnipro Dot, and a Black Sequencer.

I’d like to know how to patch my Dnipro Dot channels 1/2 into the channels 1 and 2 on the sequencer. Is this possible? Basically want to sequence/run each oscillator individually, but rhythmically with the Dot so that each step progresses with a trigger from the Dot.

Could you please tell me how I could patch this as I’ve experimented so many ways without any luck.

Grateful for your time!

Hi there,

As a guitar player who moved into modular some tips, first get the book Patch & Tweak such a great guide for beginners to modular! Next download a copy of the free software VCV Rack, it is super helpful to learn how modules and patching work.

I'm not quite sure what modules to start with. I know I need an oscillator, modulation source, sequencer and a VCA so I was thinking of Plaits, Maths, Marbles, and Intellijel''s Quad VCA

Definitely need a good sized case and power supply. I recommend 9u size at minimum and 12u if you can get that for the capable need to not exhaust space too soon. Amalgamod, Doepfer and MLDR make nice cases/power supplies.

Utilities are most important since you can get a lot of mileage with a single VCO and Filter.
You want VCAs, CV mixer, attenuators, mults, LFOs and so forth. I started with Batumi LFO, Doepfer VCO/filter, envelope generator/ADSR, and an Intellijel VCA that is great.

How would I be able to record into Ableton or perform live using a Focusrite 4i4?
Send output from mixer in modular system to an audio interface. I use a MOTU audio interface that receives output from my modular mixer and works well with my DAW and computer.

What are the best resources to get more comfortable with actually patching this rig

Download VCV Rack software on your computer and try building a modular system and patches!
The book Patch & Tweak is great as well.

I hope you're enjoying the Brenso. It's a lovely module.

Thanks for your post. I do have a nice set of monitors (DMAX SuperCubes) but this is besides the point of this thread. I'm looking to build an instrument, not to further expand my studio.
