Don’t do it.
As cool as the LXR and Endorphin.es modules sound, there’s no fucking way they can compare to the user experience of designing sounds on something like the MD. The compromises of fitting so much into such small modules will make you regret your decision.
Don’t
Fucking

this poor man’s opinion poll has been band-passed into a self-harm intervention.
I really wish Erica Synths would make a standalone version of the sample drum. I think it could compete with the DT.
I’d ask what it is you want to achieve going modular for drums — is it more about the sounds? Or the sequencing? Or interaction with your other euro voices and fx? Do you want them for live use?
Like, I’m making drums and percussion in modular, but focusing on sound design one at a time and turning them into sample instruments in Logic (can also drop samples into Digitakt etc)… which I can then sequence and modulate with my modular via cv to midi. Feels like best of both worlds to me.
Ready rolled drum modules - to me, and for the most part - defeat the whole purpose of modular, unless they have extensive CV modulation options, which most don’t seem to. So you can end up with a lumbering and limited inconvenience that probably won’t give much long term satisfaction after the initial honeymoon period wears off.
IMHO it is a folly to try and do everything in modular, and a bit boring.
I’m not interested in buying modular.
For me it’s the best way to noodling all day.
I understand for what reason it is a useful tool for synth synthesis, it remove lots of limitation in signal path, it’s mono, but you have the ability to go really far in the monophonic range with it.
Drum synthesis is quite different than synth synthesis.
First you need more voice.
It is more than useful to have tons of ability to shape the sound of each voice.
In modular either you have really really intelligent module which do it all, or dedicated module.
With that in mind, I believe it would cost a lot and take lots of space to have a good drum machine in modular.
A 2, 3 voice could make sense… kick, snare/clap, hat/noise, drone. More than that, can be a headache.
It’s usually counterproductive to tell someone else that what they’re thinking of doing is stupid. But since you said so yourself in the title, I get to just agree with you.
You have some great out-of-rack percussion devices: MD, AR, A4, DN. Maybe you don’t use the MD much and it can fetch a good price. But don’t spend what you get and more on drum modules.
I have 400+hp of modular (12u). I have one dedicated drum module, Quad Drum, and only because I got a good deal on Euclidean Circles and really liked using it. I can also craft percussive sounds out of oscillators, filters, noise sources. But when I really want to get great drum sounds, I have an A4, DK, and TR-6S.
If the LXR-02 appeals to you (it doesn’t to me), get the standalone device, or get a Nord Drum 3P, or something else at half the cost or less. Black Sequencer is respectable but you have a boatload of Elektron sequencers. QoP is also respectable but not particularly special. This really sounds like a plan you will regret down the line.
…hmmmm…what a nice mess of setup u got there…
i, personally, would always sample the vcv pearls, put some effort in curating the perfect sample chains and feed it to the lions, ur ot…but that’s just me…
but overlooking ur ballpark, there’s quite some gear that u could get rid of long before the md, if u really wanna fall for vcv discoveries become hw reality…
given the fact, that u got an a4 (a truu modular system in the box right there, by the way) and assuming u already filled it up with all possible analog drum/percussion sounds out there to get, u better let the rytm go…
add pro2 and granddmother moog to it and u end up with way more than 2,5 grand plus the advantage that it frees ur workspace quite a lot…end of the day, one universal keybed controler is always the best workflow solution if ur in for a treat and serious sonic results…
and also, long before the md u might wanna ask urself what the heck ur really doing with that novation ultarnova…and maaayybee same with the virus…same same but different?
so i’d suggest, sell the rytm and/or the sequential/grandmother first…swap ur digitone into a digi tone keys to have a solid polyaftertouch master keyboard while keeping the same benefits…
and think twice, if u really wanna open pandoras modular box instead of harvesting vcv rack for an unique sample collection…
so wait a second, sample some of ur vcv favs, let the ot tkae care of it, feed ur a4 input with ot’s cues and see where that might take u… at least for another little now…
ans whatever u think u might wanna do live performance like, there are way better concepts to do so, no matter what gear u’d like to twiddle to call it a live performance…
and never forget, whenever u think u’ve seen/heard it all on an elektron device, especially the md, u can be sure, new ways of harvesting and handling it are only one different approach/ perspective and different mindset away…
aaaaand sure, mutuable’s plaid is a simple masterpiece in sonics all on it’S own, but i don’t see any advantage to handle it in hardware than in software…it’s all about it’s sonic attributes and way easier/effective to handle/harvest in soft since u simply can open quite a few instances at once, where it really starts to shine on a whole different level…and no matter how sexy the lxr is, if it’s not able to morph between two different settings in realtime, it’s just half the power…
Since you can’t buy another Machine Drum easily in case you don’t like the modular drums it’s a tough decision. I sold some devices that i can’t get again and regret it.
But i also found some devices that fit my setup way better by selling stuff and making “risky” decisions like your idea.
I never had eurorack modules and don’t really know how productive i’d be with it. I can understand your idea because i thought about the same myself. Some modular drums sound really boring but i also heard examples where they sound so snappy and punchy that i wouldn’t know how to recreate that with other gear. Of course you can use a compressor and whatnot to get banging drums but some modular drums i heard where very special. And i know some people swear by their modular drums.
The problem is that if you don’t try it you’ll never know if it will fit your workflow. That’s why i made some stupid and some very great decisions by swapping gear.
In the end it doesn’t really matter that much because you’ll have fun making music no matter what route you’ll take.
Sorry i can’t help you. Just go with your feeling! 
I regret selling my machinedrum - and whenever I do have a sit down and mess with modular drums I end up sampling them into my AR anyway since there’s tons more control and immediacy with drum samples in the AR then what you can do with most modular drums in rack after patching your initial sound.
(You can find tune pitch to get them in key, you can have really precise amp envelopes to gate or filter - there’s only one LFO but there is also a sub page with four assignable modulations for velocity which opens up a lot of possibilities)
If you aren’t satisfied with your AR for it’s internal sounds it def makes a solid drum sampler - my preferred way to use it these days anyway.
Please keep the MD. IMO gear should only be sold if you don’t like it, not to fund GAS.
Especially gear that is out of production (MD Mk3 pls 
).
Keep MD. Stick with VCV.
I would say do it, as long as you are ok with the idea of maybe rotating through some modules until you find the right fit and the down time involved in selling, buying, and learning on such a major change. You already have eurorack so you have some vision of how this will work.
You can do a lot with a little with drums in eurorack depending, maybe look at some of the alm busycircuits videos showing off there drum modules, lots of ways to squeeze a little extra out of those modules and often times that is where you find the most interesting stuff.
why not try send midi cc from the VCV to the MD?
First, I’ve unfortunately not had time to read the whole thread but the is a subject I’ve spent a lot of time and money on. My conclusion is that it really is modular sequencing I want for my drums (odd ways to trigger, timing, etc.) and not so much modular drums (well, perhaps a few). It is hard to beat samples for most drum duties is my conclusion and the interesting part that modular bring for me is the triggering.
Do you have a CV-to-MIDI module? That was my response to the situation you describe.
Agreed! I love the functionality of that module but I hated actually using it in the context of my underpowered system. I didn’t want to dedicate like 100+ HP and all the cash just to make it useful. Machinedrum and Digitakt do everything that I wanted my modular drums to do, and more, for way less money/space.
Also, get a soundcard with DC coupled outputs so you can use your VCV with the actual modular you have.
I don’t do euro but I built a load of drum things for my modular, some simple x0x circuits, some more modular things like the cynare. While they sound great and occasionally offer some interesting possibilities really they just reinforced my love for drum machines and made me miss the one I’d let go.
It takes a ton of patching just to do the simplest things, especially sequencing wise. One of the most useful things about drum machines is having quick access to a bunch of rhythms and that’s not there. Except for the odd time I want some weird clocking it’s really a step backwards.
I think getting one thing like a kick just to have a pulse can be helpful but beyond that I don’t know. Lots of fun to be had making drum sounds with the rest of your modular though and no reason you need a high hat module to make a high hat or…
But most importantly, one of the best things for triggering modular drums is a machinedrum!
You should be able to make all sorts weird and wonderful modular drums and perc with what you’ve already got - sample and load into your Octatrack.
Or not. Sell me the Shapeshifter to help finance drum modules.
