Thanks!
*************
The Behringer Model D is a great analog synth - and by design it's monophonic. However, if you've seen my channel before, you know I'm not going to let that stop me from trying to play more than one note at a time with it, something that has a unique characteristic in synthesizers that are intended to be monophonic.
You can't control any of its 3 oscillators separately, but there's a fourth oscillator that can be controlled independently, and that's the filter - via a dedicated CV input - and when you crank up emphasis all the way, it resonates and creates its own tone. The nice thing about the D, is that there's resonance both in high pass and in low pass modes, which opens up a lot of sonic possibilities.
This does require a little configuration trick. When playing duo-phonically, the keyboard sends two notes - so we need a way to tell the D's oscillators to play one, and the filter to play the other.
In the particular case of the Arturia Keystep, which is what I use in this clip, that's achieved by setting note priority on the D to LOW, and CV out priority on the Keystep to HIGH. CV then controls the high note, and MIDI the low one. This trick lets you play two notes at once on the D.
The final piece in the puzzle is that the Behringer Model D's CV tracking on the filter doesn't quite track at 1 volt per octave, but it's close enough. If you're playing the filter notes in a one octave range, depending on your sensitivity, that might not be noticeable, but it does become apparent across a few octaves. The way to solve this is to interject a module like Befaco's A*B+C, which, with a bit of fiddling back and forth, can produce a result which tunes quite nicely. Since I don't have the module, I used the techniques shown in my "hybrid modular" video to use a virtual version of that module in VCV Rack.

Loopop has been one of our greatest musical resources over the past six months. We went from having never touched a synth to having a room full of them and a newly recorded album on the way with an entirely new flavor than anything we had done before. Many of the tools that we used to get us there came from this channel. Thank you, Mr. Pop.
My pleasure - thanks for the comment!
Your Behringer model D tutorials are the best, hands down!! This is a good example how to make a successful tutorial.
This kind of trickery really gets the juices flowing. Thanks for this!
I'm yet to own a single bit of the kit you showcase in your videos, but I always find it fascinating how you manage to find creative solutions to extend the capabilities of an instrument by understanding & demonstrating how its mechanics and design work. I really enjoy your explanation of how everything works & your thought process, it's inspired me to dig a bit deeper and think creatively with my equipment when producing.
Thanks very much - I really appreciate the comment. Yes... I love it when a piece of gear does more than it was "supposed" to...
Easily the best modular synth videos anywhere. Please keep 'em coming.
I just got my Model D so I'm soaking up all your excellent information.Thanks for that!
Great tip .!! I just got the D , haven’t even opened yet.. I’m a beginner, but this tutorial helps to expand my knowledge & get me psyched that there indeed are ways around what the manufacturer says .. cheers ! I’m glad I found this video. Subscribed ..
You are the best! The most useful videos regarding synths that can be found! Thank you!
We got a dang ol' synthlord over here. Yet another astonishing video!
Tried this combined with an FM synthesis patch, narrow square wave OSC3 modulating OSC1 in the audio range and tuned to a harmonic. Made for a crazy doomsday organ sound. Lots of twiddling to find the sweet spot where it all locks together (between modulation, osc detune, filter cutoff/contour and sustain), but it’s there. Definitely helps to set the keyboard two octaves down and run the oscillators on 8’ - gives a nice balance between the low (osc) notes and high (filter) notes.
Very impressive, Mr. Loopop. I'd be facinated to hear your story one day!
Well discovered solution and very clearly explained and demonstrated - thank you.
New to synths and just got the BMD. My friend this is genius! Thank you for sharing. And yeah I definitely subscribed. Class is in session.
You’re a legend, my friend. Great work
Getting mine tomorrow, pretty excited. And my dog walked in, just when you mentioned it, looking like wtf dude ????? She's in for a treat tomorrow.
Very cool! The Keystep and Model D seem to be a good combination.
Awesome. Thanks loopop...
Thank You! Want to see more!
Excellent video -- thanks! Subbed!
Brilliant. Thanks.
I was wondering about the tracking (I don't own a Model D, yet). I have a Doepfer SEM filter (Eurorack module), which is playable but doesn't track well. I wondered if it was adjustable, but I hadn't thought of using a multiplier to interpret for it.
I could probably make something to do that, relatively easily. I'll give it some thought.
This is the sort of duophonic behavior that made me get into the Arp Odyssey back then when I got my hands on a 2800. Unfortunately I don't own it anymore, but the Behringer is sounding more and more interesting now that I've seen your demos.
Thanks for sharing. This one might be very useful for me...this hidden duo-phonic mode.
Seems like I need to get some ES soon hahaha. Great video!
Dude you’re a freaking genius!!!
Thank God! Cheers mate!
Nice Job!
Epic hack. Thanks, waiting for my Keystep to arrive.
And Keysteps are out of stock at Musicians Friend, but in stock at BH. Overpriced on AMZN.
You are the dude!! Best synth info ever....!! ...and I don't even mean this vid in particular.... not that it's bad in anyway. I Love the channel!!
Tilman Wolff-Moore thanks ;)
Tilman Wolff-Moore thanks - I really appreciate the comment ;)
Great stuff! Greetings from Brasil!
Very nice thank you!
Thank you for your Tutorials!
Do you have an idea or someone else, how you could link a OSC tune knob to a Modwheel to tunes notes up and down?
Legendary
I learn so much every day from yours videos & it helped me buying my model d also,I was wondering can you play duophonic using a minibrute 2s & model d
Thanks and Yes you can play them polyphonically or duophonically
@@loopop thanks a lot,I might be asking for to much but could you do a video on that in future because I could not figure it out myself
Keystop pro is next on my list.
I am experiencing a new problem with my Neutron which won’t let me detune oscillator ones tune knob no matter what I do . Any idea what’s going on? I ready to throw it through a wall after all the tuning issues with the d. Peace Christo
thx man i wished that I could do that!!!
my midi keyboard is usb only and doesn't have a cv port into it (I have an Oxygen49 from M-Audio), will it work?
can we do this with ableton's live daw instead of Keystep??
Hi, I've bought a behringer K2, but I don't know if the model D sounds very different. I hesitate between it, the neutron and the odyssey...
Thanks for sharing this clever workaround. I have seen a few people detune two oscillators to play chords, but not this trick for having two separate lines of music. I am assuming that this could also be done with the Neutron?
Yes, though Neutron allows for this more directly, check out my video
What do you think are the advantages of theBehringer D over the Korg minilogue? thank you
Amazing
Any chance this would work with an MPC live's CV outputs instead of the keystep?
so, my akai mpk225 doesn't have a cv out option,but if I were to get a midi to cv converter, could I run that from the midi out on my interface to the cut cv jack on my model D or would I have to go straight from my keyboard for it to work like you're doing here?
Awesome video! Any idea if it's possible to do something like this with the MicroBrute (or another synth that has pitch out but no MIDI out)?
Benjamin Kleeman thank you - yes - I already showed this with a microbrute. Check the channel ;)
As always, very good video. I do have a totally different question for you: can you tell me how you created the vies of the waves in the tool at the top of the screeen. Looks like an oscillograph, but it may be "only" a software tool. Thanks a lot for letting me know from a Behringer fan in Germany; at the moment I do have the odyssey, the Vocoder VC340 and the Deepmind 12. However I am thnking to add to this either the model D or the Poly D.
Thanks! yes it's just a software tool - I use MOscilloscope and MAnalyzer by a company called Melda - they’re free with some limitations in the MFreeFXBundle. Occasionally I’ll use scopes by VCV
I can't wait to get my hands on this beast. How long can sessions be with this synth? I feel like you could get lost for hours tweaking sounds!
bought one today, spent a solid 6 hours, and only stopped because I had to leave the house
can you please explain how to hook it to maschine mk3 please im having the hardest time getting info on it and all the ing ive tried didn't work
Hi thanks for the idea! I don’t actually own a keystep or any other gear with cv outs... do you think what you show is possible with just model d’s internal patching?
Not that I found so far :/
Not sure why they didn't give us CV over all 3 oscillators. Probably a fatal flaw for Eurorack along with the size of it.
This helped a little, and it just sounds cool
I want your opinion too: do you think the Arturia Keystep has a niche place in the MIDI controller market? I was looking for one for a while but couldn’t find one but then I found the Keystep
Not sure what you mean by niche place but there are few products I can recommend as strongly as the KeyStep. Inexpensive, durable, small, sequencer, arpeggiator, MIDI and CV outs - must have in my book
Hey. What software are you using for the visual Wave and tuner etc?
Genius
What a bummer the filter is not tracking accurately. Do you know if there's an internal pot that allows tweaking the V/Oct of the Filter?
Yes. 3rd picture, here:

Hello Mr. Loopop, need some help with my model D, Just a short question:
I use my Kenton pro Solo MK2 with the Boog to play it with Velocity to Loudness or Filter, this works fine , but
but I loose the Amount of Contour Control funktionality, and the Glide Function is also gone. Played over Midi no issue, ---but I like the use Velocity. Any Idea ?
Kind Regards
Thomas
Not familiar with that one
Great tutorial. Superb. Wanted to ask, can Model D respond to a keyboards Mod Wheel?
If I remember correctly yes. This was a loaner
Nice tutorial!!do you think I can do the same if I pass on the volka Keys without the module?thank you!!
Thanks! I’ve never used one unfortunately
can u modify the cv oscillator or it's just that flat sound?
Will this work with the beatstep?
Hi, nice video. What kind of audio visualizer do u have above?
Fer Tigo spectrum from ableton
can i combain 2 POLY D to 8voice poly synth ?
Nice
Thx‼️‼️‼️‼️‼️
Thank you sooooooo much for this! A+++++++++++++++++++++++
Como consigue la pantalla donde se muestras las ondas o frecuencias? Gracias
Hi, I use MOscilloscope and MAnalyzer by a company called Melda - they’re free with some limitations in the MFreeFXBundle. Occasionally I’ll use scopes by VCV
Does this also work with the KeyStep Pro?
Hi, thanks for the video. Does this trick work with the SE-02 as well as it does have MIDI/CV?
Perhaps - I don’t have one so can’t try
The SE-02 has a "VCF CV" input on the back and the two Keyboard tracking switches, but I don't think you can set note priority like you can on the D. Don't see it in the manual, at least. There are modules out there that can do that for you though! I'm pretty sure Yarns can do that.
In your opinion, how does this synth stack up against the mother-32? which device would you deem more flexible/powerful (standalone) and why?
You know it's funny I had them side by side to compare the bass the other day and Mother-32 had more oomph with one oscillator than this with 3 - but other than that, there's no short answer. 3 means more tonal flexibility and D still sounds great. Since Mother has a sequencer that makes it more flexible standalone. Of course add a keystep to the D and you get a keyboard, sequencer and arpeggiator, and it will still cost less than the Mother-32. Also, are patch points important to you? Mother-32 has the advantage there. Anyway, no short answer, but I made videos on both so hopefully that will help you decide...
thanks for the reply! will be a tough decision indeed lol
I think there should be a v/oct trimmer on the pcb for the filter.
toxto If the circuitry is the same then yes for sure 👍👍
when I looked in the manual I couldn't find one and didn't want to go around poking a screwdriver again... this might also help people that don't want to open up the box
@@loopop, VCF Scale is shown in the 3rd picture, here:
www.gearslutz.com/board/modular-mania-all-things-eurorack-and-modular-synths-effects/1218816-behringer-model-d-diy-mods.html
Your black box approach was interesting though.
What did you use for visualizing the sound wave?
Scopes by Melda and VCV
So this is not aviable to do with your midi keybaord has no putch cv out, I use Novation Impulse 61. ;(
Will this work with a Behringer Swing?
as we need external devices... it seems to be cheaper to buy a second Model D to have the duophonic thing ^^
Hi Great video , but novice on sysex midi controller , what SysEx do you use ?
No need for sysex. Everything you need is in the video
@@loopop Thank alot , find it and work properly , thx for your quick answer !!
This should work with the behringer neutron as well. Correct?
With minor adjustments yes
What software have you used for tuning?
ableton lives internal tuner
What happens if you put the Keystep in chord mode and put it through the Model D?
Model D will pick one note based on its note priority
@@loopop I assumed, but didn't know if anyone had tried. Thanks for the reply!
10/10 Dr. Seuss rhyme schemes.
I just tried this with my Moog Subsequent 37 CV and my Behringer Model D with strange results. Using the cv out mapped to “KB pitch” didn’t work, but mapping the cv out to the pitch wheel did. So is the pitch wheel cv and pitch out ... something else?
Can you please show how to set it up in the daw plĺlllllllease
what's the problem? what do you mean?
@@loopop how do i set it up with my daw ( studio one) please
Hook it up with a Beatstep Pro(cv) and show us or me more?
Please.
Sorry, this unit was on loan and I don’t have it anymore
@@loopop A thumb up only because you don't have it. I know there is much gear to see and keep.
Lust and what is usefull is difficult in any rig.
hi I did all the steps, but still it doesn't work!
Everything I show in the video is real - don’t know what to say... I make videos because text sucks for this kind of stuff. Try again maybe?
@@loopop thank you for replay. I did it many times . but I could not change priority of behringer manualy but I dit it via model d app. any way I do exactly what you did and I hier the second key but very very low velocity (almost not hier it)
regards,
Saman
I'm in the same position... Followed the video, changed Keystep to High note priority on the MIDI Control Centre and changed the D to Low priority on ghe SynthTool, tuned the oscillators and filter by ear etc... High notes doesn't play when i have a low note held down... Any help? I'm new to all this stuff!
and theres a mod for pwm, sync and play all 3 independently (not as big a fan of this one for numerous reasons)
So you can't do this without the keysteo?
true
O rip me haha.
It's a really cool feature wtf.. like that brings this boog up to another level 😏👍. Imma check the shitsteps that have good action...haha been needing a new board 🤪
Request : duophonic Behringer K2
I show how to do that in my K2 video, but based on your previous comment why not just buy another one... by the way, you never answered my question whether you found anything unreliable in that video
@@loopop On some point I can rely in what you say but not blindly, as the company gives youy the synth you talk about. When there are cons, you elude them or show them in a positive way.
@Barbie Chêtif please name one con I eluded. I do however try to keep an overall positive attitude, and aside from that, of course, I don't expect anyone to follow anyone else blindly.
@@loopop I try to be honest, not speciallty negative.
You should tune it to the note you're playing on the keyboard though :D
It sounds great but am I overreacting by thinking the “out of tune” thing is a dealbreaker? I want to buy one but that issue is making me hesitant.
Michael Young well this is different - this is the filter cv, which wasn’t advertised to track 1v per octave. Regarding my previous video about tuning overall - I agree is an issue otherwise I wouldn’t mention it. Not sure I would call it a deal breaker, but yeah opening it up wasn’t fun
loopop is that synth “os updatable”? I’m thinking if it is, I hoping behringer can and will fix the tuning issue with an os update.
Michael Young yes it is updatable but I don’t think that portion is. Again, what’s shown in this video is ok, in my previous one - an issue to consider
loopop If the d is under warranty, wouldn’t behringer tune it for you?
Weird, you tune for an A while you're pressing a C on the Keystep.
I know... doesn’t really matter. You can tune to C of course... sorry if it’s confusing
Haha I mean it matters of you're trying to play in tune with someone/something else but if all you care about is your synth then yeah I guess it doesn't matter
Out of pure oscillator-greed, I have to ask: Does this trick work with the Poly D as well?
its has the feature built in
@@loopop It has a built-in feature to use the filter to gain 5 notes of paraphony/polyphony instead of just 4?
Chris Gadd oh that’s real greed, I thought you meant to play it paraphonically with the oscillators. Sure you probably could somehow, not sure it’s practical or worth the effort
@@loopop Sounds like fun to me, then. :-) Thanks for the reply!
3:42 ... No dog, but the cat is jumping all over me. If she could talk it would go something like, "Make this STOP!! PLEEEEEEEEZE!!!!!"
What 7 people don't like this? Who are these heathens?
It should be paraphonic
This is a really neat trick, but, honestly, if you want to play polyphonically in 2019, than a Minimoog isn't the thing that you should be using.
Use some other eurorack gear, ok fair enough!
Can you please tell me what the brand/model is of the screen your using for the waveform visualisation? Thnx!
this is awful because you tuned the C key to A
why would you DO that
It’s the least I could do to annoy the perfect pitch people who feel the need to leave comments like this
If I hear another person make claims of an extra vco by putting the filter's resonance at 100% and using the cutoff level to tune that vco, I'm going to lose my shit, yeah sure, technically that could be measured by an oscilloscope, but your giving up use your filter, for a shity, barely in tune sine wave that also keeps one from modulating anything "practically" that would involve the filter. Synths dont have key traking for nothing, it's self explanatory, this is not a new discovery, many synths have this feature and it's not some kind of mystery, key traking should be obvious, wouldn't be so bad if you didn't seem so proud of yourself.
How myopic of you to think that just because you know something, everyone else does, and what a waste of your precious knowledgable time to even click and watch a tutorial with this title. Quite a lot of people don't know this as you can see from comments on this video and others where I show this trick. Even worse, I'll keep showing it because it's a cool one, so you really should stay away from this channel else risk "losing it" quite a lot. Tracking works quite well in this synth and others and not many people know that it's a great way to play another kind of tone with a synth - a standalone sine wave, not to mention in conjunction with another oscillator.
WHAT SORCERY IS THIS?
