A sequencer would be very low on my list to add-on to this synth, I mean how much time have you put in with the Matriarch's onboard sequencer so far? I was originally thinking "brand new to this synth" and the follow-up questions have me thinking "brand new to all this stuff in general." What do you find lacking or hindering when you sequence the Matriarch right now? I wouldn't buy another sequencer without being able to answer that question, and appreciate the fact that you're about to more than triple the total cost of this Moog set-up through filling 300HP of modules, so you should really hesitate to grab $600 or $1000+ modules that you're feeling wishy-washy on. There are a lot of extremely nice external sequencers in this price range that run circles around anything in eurorack.

No experience with the Metropolix. You could use voltage adders and switches to get chords going from a single sequence and quantizers may have this built in. That Sinfonion is built off the Harmonaig, which would be closer to "making sense" with the Matriarch if you must have your chords generated from a racked module and not the keyboard or something else. Just remember that the synth's keyboard isn't going to behave normally while you're sequencing the oscillators. Look at the Behringer 1027 as a much cheaper option.

I would stick with the more basic toolbox modules mentioned above and then see how you feel after a month or two. The Matriarch's magic is coming from the base component modules. You could go nuts with envelopes and mixers and companion VCO's and make it behave polyphonically if you wanted to but you'd be halfway to the price of a moog ONE with 1/4th of the voices. So really imo at this stage it's better to get some time with the synth and see what you keep reaching for while patching rather than to whiteboard it to death if you're submitting things like the Sinfonion as a question.


If I had to come up with a partner 120hp row to permanently sit on the Matriarch it would look something like this. These modules tend to get the most mileage with the synth.

The rear panel module is very useful and is so cheap that something equivalent should have been included with the synth.
She desperately needs more mults and attenuators/attenuverters.
Chaos/random CV (I use Wogglebug and Sloths).
More LFOs or envelopes and a VCA/mixer or two to help with those.
Ring mod if you like it, imo much better with something external to free up the built-in modules.
A high pass filter so you can run mixer -> hpf -> stereo lpf.
Your favorite stereo effect or a pedal interface module like strymon's AA.1. Patching from the filter -> your effect -> back into the matriarch's delay is a dream for example.
Lots of options for this since the Matriarch feels so "finished" in most ways to me, really depends on what you are doing with it and where you want to go. A Pam's might be an easy suggestion for some people but I don't really sync up that much modulation with the Moog in practice. It does so much work on its own that I find myself mostly using "the more basic stuff" to augment it.

Combined the two into one module, total HP from 13 up to 14 but reduced the depth from 45mm to 33mm, I'm guessing that's where/why the additional power draw manifested. I'm a little annoyed at my Batumi+Poti combo because the 3HP expander could easily be 2hp and so you end up with an odd-HP module to find a place for, but they aren't leaving my rack anytime soon. This looks like a skiff-friendlier alternative if you really love Batumi, but I'd probably reach for an Ochd (4HP, 32mm) for skiff duties at twice the price for twice the outputs in a third of the space.

Efficiency on the wallet is compelling but I got mine, I'm down the hole, I don't need cheap modules to tempt or help me to get up and running. However the suite of cheap euro clones that don't fit into one of the big 3 systems is starting to look like a great gateway drug to the big boy modular companies where innovation happens. Brains, Abacus, 4LFO, 4Play, Mix, and Space FX total a little over $600. Add a filter like their 121 Dual VCF and you have substantial power under your fingers for USD$724. That level of buy-in could inspire a lot more artists to give modular a shot, anecdotally I sure wouldn't have plopped down $2000 for a Moog if not for the B2600, and here I am balls-deep in even more expensive synths because of that Gray Meanie.

I don't think this counts as IP theft either unless Behringer decompiled XAOC's code which wouldn't be necessary for something of this complexity. This is a quad LFO module, pretty far removed from some unique and magical DSP-based products, and just knowing the basic functionality of Batumi you could replicate it with some textbooks and time. What is the element of Batumi that makes this an infringement - what is their intellectual property at risk here? How many VCOs or EGs are functionally identical with a different coat of paint? It's sad how quickly I see people run to "the law" in an effort to enforce their personal moral or ethical perspective when it's one German in particular. This is no counterfeit product wrt trademark theft: different looks, name, decorative symbols, logo. No one is confusing this for the XAOC original by mistake; the Four LFO is derivative but not counterfeit, or is it time to re-litigate the "your guitar body shape looks like my guitar body shape" issue? It seems like Behringer is operating within the bounds of "the law" that you want to use as a cudgel to beat them with, shucks, maybe grievances at this company are misdirected. If you find it morally repugnant then please lobby for the law to change rather than bleat onto the internet, it's a very sad "man shakes fist at cloud" situation to observe. Just FYI - anyone can report IP theft to the appropriate agencies and you don't need to be the owner of said IP to do so, just seeing it occur is enough. Go for it and post the results please, I'm not being facetious, we wanna know the outcome!

I'd much rather get some unique modules out of them and at this point I wonder if they're aping "tried and true" products to test the waters to see whether modular development is worth the full-time investment after the Roland100/Model 55/ARP2500 stuff. Behringer seems to have started slow and built up steam once the sales rolled in with their desktop/keyboard synth offerings, makes me wonder, but then again we're seeing more clones rather than releases in the same vein as DeepMind in that arena (and to be fair, originals will take longer than eyeing a template). This current batch could also be products that largely function for the company as advertisements for open positions, I think they've been seeking devs and designers for awhile now. It's not like euro fever is slowing down (though a depression may force it) so imo it's time to shit or get off the pot. Rehashes bore the fuck out of me from any company. Behringer's unique weapon as a company is extreme efficiency of margins, I'm seriously waiting for the "look at everything we could afford to slap together" Frankenstein's Monster that's too ugly, strange, and crazy to resist. Popular Module #69 doesn't tingle the peepee much to someone already entrenched.
