Polyphonic 6U104HP gearlust setup using four AtomoSynth Koe voices.

I know it's a bit arbitrary, using only black-faced modules, but it looks niiiiiiice.

The low price of the Koe modules makes this a reasonably doable project.

nice!

Certainly, when they're 20-odd years old! They buy me the occasional pint of ale as well. If I knew they would someday be buying me modular gear I'd have had more of 'em.

Submit button working again?

Kids can do this?

Nine months in and this is how my EuroModular looks after my Father's Day present of a Medic Modules EKG. Thanks Son!

How about a Eurokorn for Christmas?

This my attempt to emulate A Oberheim SEM 4 Voices Polysynth. I added 4 ADSR to control the VCFs and 4 VCOs to get 2 osc per voice. The fx section is optional but one can dream? I think this could be a very obese sounding synth. If somebody can find a cheaper alternative (all analogue) let me know. 4 more ADSR to control pitch and a Quad quantizer for the slew limiter to do like the glissendo of CS80

Just built a two tier case out of pine to accomadate new modules.  Building a lot of Hexinverter rhythm modules for now.  Needed more room. 

Good !!

comme filtre oscillant de belle manière et de plus avec un tracking très correct (avec entrèe 1v/oct), tu as le double filtre  Korgasmatron - http://www.intellijel.com/eurorack-modules/913-2/, j'en ai un, j'aime beaucoup

et l'utilise aussi comme oscillo, de plus il a une ergonomie assez génial. Par ailleurs il sonne bien en tant que multifiltre 12db, beau caractère

j'ai bien hâte de t'entendre sur ces nouveaux instruments

merci pour les commentaires. J'ai plongé mais le plan c'est d'avoir 4 (ou 6) x 84hp d'ici la fin de l'année ;-) J'ai le budget d'une commande alors oui je vai explorer Cwejman... je veux deux autres filtres car je m'en sert souvent comme oscillateurs sinusoide... ça sera un prochain poste ;-)

Une année avec du temps et un peu de budget, ça devrait aller ;-)

Continuez à envoyer des recoommendations, je suis toujours ouvert!

p

regarde aussi du côté d'intellijel et leur Dixie II, oscillateur simple mais d'un tracking irréprochable et d'une qualité mordante, connu aussi pour la pureté de son sinus

très important tu t'en doute pour moduler...tes AS 95-e par exemple

en lisant la description du VCO sur ton blog, j'avais l'impression que tu décrivais le DPO de Makenoise...

Hello PA, 

que voilà une bonne idée, a première vue comme ça, bon je sais que c'est pas fini, il faut des vca. 

On a jamais assez de vca, et pas seulement pour les envellopes mais aussi pour les lfo. Tu semble aussi attaché à AS, qui est super, mais regarde aussi 

du côté de Cwejman, et surtout pour les filtres. Par ailleurs deux filtres pour un système de cette taille me paraît beaucoup (mais pourquoi pas ? )

personnelement je suis plus tendance west coast synthesis avec l'idée des oscillateurs complexes et des waveshaper, mais par ailleurs on peut aussi faire ça avec des modules comme les tiens. 

Bon voilà c'est passionant, mais fait gaffe, c'est cher et addictif (hé hé ). Voilà mon modulaire tel qu'il sera vers Juin prochain (j'y bosse depuis deux ans, mais je suis super content) il est transportable

dans un folding case en ABS (ultra-lèger, si tu veut je te filerai le contact du mec qui les fabrique) -

ah une dernière chose, ne néglige pas l'alimentation, c'est primordiale !!

Best

reorganized for less external gear hooked up. out of the box remains sequencing(orb+ipad) and some noise/drone.

Excellent choice of modules! 

This is my current rig - a 9U Goike and a 3U PM Move Case for the bottom row.

good idea!

Duude, it took me a month to see your comment! haha

Yeah man! Love your vines! Keep em comming! :)

Hey I saw this in a Vine today! I'm Wogglebug 303 on there ;)

For all the noisy digital & cv processing modules

3U TTHEK with Doepfer power rack mounted into a shelving unit ;)

(second row is a 44HP Lamond Walnut mini skiff)

Main case:

looks crazy! 

Yeah, and the Gozinta arrives today. 

I can see that you have unpacked some more bubble wrap!Wish you good fun with this machine!

The final piece!!! This rack will have the seq/quantizer/lfo/grain dly/5ch mixer/multi from the 1st setup and will add another sequencer/quantizer and lfo, as well as more multis, a filter, an analog dly and another 5ch mixer  

this will be my live modular rack. I have a little phatty w cv outs and an sh-101 so no need for midi, and I'll be building the expanded Sequencer/FX rack after this. I also have a Volca beats that will be sending clock signals to everything So again no need for mid.  

can anyone give me any comments as I've never built a modular system before. I know enough about synths to get by but have I forgot anything straight forward?

I'm selling the left-hand side!

why not use 4 synth voice modules like these http://www.modulargrid.net/e/analogue-solutions-stationx http://www.modulargrid.net/e/doepfer-a-111-5 http://www.modulargrid.net/e/acidlab-m303 http://www.modulargrid.net/e/pittsburgh-modular-synthesizer-box http://www.modulargrid.net/e/atomosynth-koe-v2-0 and a mixer like this http://www.modulargrid.net/e/circuit-abbey-unify with the relevant midi interface

you can pick and choose what you like it is modular after all

Just passing through, and I've never attempted polyphony in a modular, so take this with a grain of salt.

Basically, I'm getting kinda mixed vibes on this setup. The only reason I can think to have four identical oscillators is that you want to have single-input instrument / multiple voice polyphony, e.g. an analog polysynth. From that perspective, it seems like this has a ton of redundancy. My understanding of the block diagrams of most analog polysynts is that you'll have your multiple vcos fed into a mixer, then have that fed into your signal chain of vcf/eg/vca, etc. from that view of polyphony, it seems not only kinda weird that you'd need a vca (and a summing vca, at that) + eg + vcf + toolbox per channel. if that's where you want to start (keyboard poliphony), you can probably get by with 4 vco, some subset of mixers, 1-2 of the dual vcas, vcfs, and egs. basically, this could probably be chopped into a 6u. it also seems to me--again, having zero true modular polyphony experience--that it'd be the hugest pain in the ass to get four full, independent voices to sound anything similar to coming from the same synth, but that just may be me being a crybaby. for example, i could be wrong, but it looks like the slew limiter in the toolbox does not take a cv in, so good look unifying your polyphonic portamento, if...that's what you're after? 4 s&hs seems like overkill, so maybe that's why there are four tool boxes..unless they're for inverting the envelopes?

"it I am thinking of using to turn the lowest voice of 4 voice poliphony into a rythmic beating bass line"

this makes it sound like what you're after isn't like true keyboard polyphony so much as "multiple voices doing different things". if this is what you're after, me personally, i'd suggest some different sound sources or filters, etc. 

i'm also separately confused by the proclivity toward mixers here. each of the four voices has a dual vca w/ 2x1 mixing, then the far right has another pair of 3x1 mixers and 4x1 mixers. i may be over thinking that one, and you may be intending these to serve also as cv attenuators. i guess it's possible you're intending on taking the already complex signal from the vcos and mixing them with some other output from the same vco, and having that serve as the complex voice. that'd be rad as hell, but at the same time, yield so crazily varying results between voices, that i'd just look into different types of voices.

overall, this looks rad as hell, and if you've got the $$ lying around, go for it. it just seems to me that it's got a ton of redundancy, depending on what you're after, either in terms of needlessly repeating the same signal chain (e.g. attempting polysynth stuff), or making the same blip bloops with the same modules but playing different lines (pads and leads and bass with the same voices) where you could be employing other interesting modules.

i enjoyed this more than i should have...thanks!

So I am thinking of building a modular, It will be my first one but I have a lot of other gear including a few mono synths. I know that a modular mono synth is loads of fun but I want a poliphonic one.There is a music shop here in Iceland that is realy interested in selling modulars so they asked me to help figure out what companies to start working with. I sugested MonoRocket for cases, Pittsburg modular, Make Noice, Mutable instruments and TipTop audio. I think with these companies there should be a nice variation in emphasis. In return I get a bit of a discount and well more good will then I have today. So here we have a 4 voice poliphonic beats. The top two rows are basicaly 4 voices, each voice has a Oscilator, Filter, Dual VCA, Envelope and tool box. Each row has two of these voices and at the end a mixing section. The bottom row has utilities for more complex opperations as each of the voices is pretty standard. Here we have a Yarns for the 4 voice midi control, Tides Wogglebug and Maths each followed by a mulltiple for aditional mangling of the four voices. and then a LPG that I am thinking of using to turn the lowest voice of 4 voice poliphony into a rythmic beating bass line and then a phace shifter to give the whole voice a final shimmer and finaly a outs. I am not compleatly shure about this as a first purchase... maybe I should start with more variety and spend less on more... I am hoping this set up will produce "HUGE" pads and string sections...Any thoughts? All discussion would be nice.

an album made with this modular + minibrute + recordings. it is a great machine for live act!

Joined two Pittsbugh Modular Cell 48 cases.  Skiff is powered by the PS built into the left hand case.  Used a bus cable from the right hand PS and connected to the unused connector on the left.  A single 1A supply is more than enough to drive both cases in this configuarion.

Added dual VCA, Function, and changed to Ripples for the filter.  Want the Cwejman mmf-6 as a filter instead, but 1. no more room, 2. no more money.  (Trying to keep to $5k.)

Eventual plan is to split off into a controller/sequencer skiff (adding Pressure Points, etc.), and add more to the main rack, e.g. additional envelopes/modulation, Maths, mmf-6, and so forth.  Might need to split off a Tiptop drums skiff also... at which time a whole other rack might need to be started instead, and thus the sickness continues...

Comments?  (Anyone know of a better and/or more compact voltage-controlled ADSR than the A-141?)

See my version 2: 

Thanks for the tip, I realized the same thing and I'm revising as such.  I thought I might be able to get fancy with Frames to do some of that, but I've reconsidered.

You will probably want to add some VCAs, otherwise you have no way to silence your oscillators.
