BEHRINGER MODEL D OSCILLATOR TUNING GUIDE
ฝัง
- เผยแพร่เมื่อ 27 ส.ค. 2024
- Because analog synth components like oscillators can drift in pitch over time, or due to temperature changes etc, we have a created a tuning guide to show the tuning procedure. Please note this operation should only be undertaken by either a trained technician or someone with relevant technical ability, as any damage caused during this procedure would not be covered by warranty. If you are unsure then please don't hesitate to contact us for assistance: www.music-group...

how many companies out there have this approcach to diy repairs/maintenance? I'm really impressed with what Behringer has become, they're doing an amazing job not only making accessible tech but also sharing knowledge with the community and listening to feedback. hat tip to everyone at the company.
This is not a repair. It is a calibration that I'm pretty sure could be done in the factory. The price is very low though, so I'm not complaining.
@@eliasknaapinen that's why I included "maintenace" (even a perfectly calibrated unit may eventually need recalibration). The problem with doing a very precise calibration from factory is that it would make the synth more expensive. They do make a quick callibration I'm sure, but some badly calibrated units will slip by QC every now and then. I also don't see it as a problem, since it helps keeping their synths cheap (and Behringer does a great job teaching the process anyway, which is what I really like; I'm all for shared knowledge on how to keep your instruments functioning properly).
@@nonono8788 They keep it cheaper this way, but it means you're getting a marsupial synth: it's born before it's really ready. Most makers spend the extra money to get it right before they ship it.
@@NuisanceMan It's an analog synth. Parts drift over time - That's not something that anyone can prevent.
This synth is very close to the original design by Moog, and the calibration procedure demonstrated here is the same calibration procedure that Moog put in their manual for the model D.
They could have redesigned the Model D to use DCOs or digital oscillators that wouldn't drift - like they did with the A standard - but it would lack the sound that made the Model D desirable. It wouldn't be an analog synth.
im curious, isn't a DCO a digitally controlled analogue oscillator? why then would it not sound the same (apart from being in tune)
Just calibrated my Model D for a first time. It was bit stressed when you never done something similar,it took me 30 minutes to tune all oscillators back and forth. Thanks for a video, It really helped me a lot. Regards,Dado.
How many times have you had to tune it ?
@@crgl2009 So far once in a year.
@@DadoSimicStudiostriver ok, thanks
@@crgl2009 You`re welcome.
I have an early model and tuned the vco's by ear because the vco's would only stay zero beat for 1 octave or less. Took me half an hour but after tuning it right, all three vco's lock for about 3 - 4 octaves. Stays perfectly in tune and the leads on this thing are amazing now
hi Zaphyd ,nice to see you got one of these too,i enjoy your music:)
I have a year old Poly-D and this was invaluable. Thanks for the info. My Poly-D is about a year old and as soon as I receive the insulated screw driver, I'm diving in.
Thank you for this super easy to follow guide. I unboxed mine and OSC 2 was sharp and OSC 3 was a half step flat. About 12 minutes later, everything is now in tune. Now I'm ready to rock out with this beast!
I wish my Arturia MINIBRUTE was half as consistent in its tuning across 4 octaves.
Actually really easy, nice video! Also... bizarrely satisfying. Zero experience with this kind of thing, so people don't let this put you off. Some tips, the screw holes underneath actually move, so line them up with a small screwdriver when the faceplate is back down. Trim pots, they turn different ways to raise/lower, so don't expect turning left on both to lower ;)
Thanks bro, the tuning is super simple but it's useful to watch someone else doing it the first time
Thanks for the video. All of my oscillators were playing a whole tone flat so, compared to the a-440 tone, my "A" notes were playing at "G". Using a tuner to get it spot on, I had to turn the OSC range calibration screws quite a lot to get them up to A. The Scale's weren't off by too much although Oscilator three seemed a bit more temperamental than Osc's 1&2. Once calibrated though, there was a huge difference, with the oscillators staying stable and in tune with each other across the octaves.
Just a small note in case you get the same problem as I did - when reassembling and putting the mini bolts/screws back in, one of them refused to tighten. Upon inspection I noticed the nuts on the main body are in a sort of rail and, in this case, the nut was free to slide along the rail and out of alignment with the hole on the front panel . Once pushed back into alignment with the hole on the front panel the mini bolt tightened perfectly.
The whole idea of getting into the electrics seemed slightly scary at first, but it proved relatively simple to do and well worth the effort.
Behringer Model D warming up now, time to tune this baby!
I had to do mine out of the box new...It was delivered to me in the northeastern US in February...I'm sure the transit in unheated containers had much to do with it...Some feedback on the process...First, those single turn trim pots are very imprecise! Talks quit a bit of work, even with an electronic tuner. The most frustrating part of the process is fastening the face plate back into the chassis. The screws meet with square nuts that slide along rails! matching the nuts with the screw holes is a step that should not be hard to complete. Those nits aside, the process is straightforward if you follow the simple instructions.
Rise Of The Machine I live in the southwest and mine will be here in June. That doesn’t mean I’m in the clear with not having to tune mine as well do you think?
From what I've read, it seems many people are getting them out of the box in tune. It was very cold here in February 2018, probably more severe weather conditions than the Southwest US in early summer...SO I would probably not worry much - But I would check it...You can set the controls as per the diagram here at 6:19 and at that point you should have a good idea where the tuning is at...And after that...Enjoy your Model D! it is a remarkable instrument!
im loving this synth!
Thanks for this tutorial. I just calibrated mine too (I bought it less than a month ago). It only needed very little adjustment. You could not even notice from hearing the sound. I had to use Ableton Tuner to notice one of the oscillators was a little bit under tune.
How many times have you had to tune it ?
Did this today as mine was way out of tune when i bought it off eBay from someone... It's really easy to do and the sounds from it are now incredible!!!! Thanks for the video!! :)
I would tune it on the octave I use when playing, but one I started getting into arps and switching octaves I noticed the drift from each octave flat or sharp. Finally really noticed it when after 20 min of working on a lead doubled with another synth I has the ah ha moment. Guess I'll be doing this tonight!
Did you do it ? How many times have you had to tune it ?
Exactly what I needed. Thank you!
Just bought mine. Thanks for the informative video.
Thank you! Really handy video 😊
I enjoyed this presentation on the chooning of my model D. Even though mine came perfectly in tune (according to several medium end end guitar tuners) over nearly the entire frequency spectrum.. I was blown away after each test, considering some people had to use multimeters to tune theirs.
Wow my Roland Jupiter 4 from 1978 , has 4 trim pots on rear panel, you like to copy, copy that, no gutting internals and flipping it over on a cardboard box to tune it> fast forwards 41 years.... progress
reverb.com/au/p/roland-jupiter-4 yea i'll stick to my 219$ model D, thanks.
Thanks but why not just have the tuning pots accessible on the outside rather than having to poke around awkwardly and possibly hazardly on the inside?
Wow pretty straightforward. I was nervous this was something I couldn’t do my self. Are most analog synths this easy to tune?
No, in most cases you're going to need an oscilloscope. Especially with the vintage ones. In some cases you need a volt meter if you're calibrating the voltage rails.
Very cool, interesting they have already changed the trimpots.
This is good. It's not easy to make precise adjustments with single turn pots. Multi-turn pots have more precision and faster to dial in setting.
Much Thanks for this. Hadn't needed this yet, but it is great to have this advice available to me(us?).
Why does this happen to the oscillators?
Jeez. How often do you have to do this? And do you have to let it warm up for 30 minutes every time you want to play it? Can't say that makes me comfortable getting one...
When should I do a Pitch/CV calibration? I have already done exactly as this video describes. Yet, I do see in the manual about Pitch/CV calibration that involves a SysEx command.
Why does my model d have blue components that do not appear in this video?
its the same but its less likely you will break it
When making a statement like "tune the A2 note", please also give the frequency.
Most people would define A4 as 440Hz, for standard western tuning, but Yamaha called that note A3, and others also use that definition, especially for synths.
Yamaha is doing it wrong then, or you misread. Those are fixed definitions.
@@angelainamarie9656 Yamaha are a major synth manufacturer, so their definition is just as valid as anyone else's - and a lot of people use it without making it clear that's what they mean.
If they've been doing it "wrong", they've been doing it wrong for decades, and no, I did not misread it, as 30 seconds using google would have confirmed for you.
Yamaha: "C3 is 3C (hexadecimal)".
Most, but not all manufactures "note 3C (hexadecimal) plays C4" - but it could just as well be C5.
So, to tune a synth I need to know which MIDI note number to send, or what pitch I'm trying to produce. Telling me to play "C4" is ambiguous, in this context.
How do you spell colour? Is it "color"? If so, is one of us "wrong"?
@@TooSlowTube I agree 1000000%. Saying "play A4" is an ambiguous term... In the programming world, we would say that could result in an "off by 1 error".
@@TooSlowTube yamaha and moog are the only 2 company who handle everything in a different way, just as moog had s triggers when everyone was using v triggers. so yeah, yamaha is a nit strange like that...
A very serious question as I really like this synth and I am considering buying one: why is Behringer selling a synth that needs this kind of home adjustment? My Pro-1, Neutron, TD-3 and the non-Behringer kit that I have do not need any of this work.
I'm sure you found your answer long ago...but if you didn't...this was supposedly inherent to the circuitry they cloned from the moog schematics...aka it's how moog designed the circuitry...they cloned it...so it had to stay the same...supposedly not quite since I'm sure the moog was much more difficult to tune...I believe Moog calls it "character"...
@@BendApparatus "Well, my boy, having your synth go out of tune is precisely what builds character!"
@behringer is it possible to adjust the "Scale" to have more (or less) than 12 notes per octave?
Thank you. Really informative !
Just done mine, twas easy, sounds nice now.
Hello,
Last time I turned on my Poly D, OSC 1 & 4 were completely out of tune.
I've waited for 30minutes, switched the device off and on again but nothing changed.
I managed to calibrate the Oscillators with the trimpots on the back panel. However, the oscillators are going completely out of tune when I change the range (from 8' to 4', to 2' or to 16' etc.).
Do you have any solution ?
Do you kwon what is the OSC RANGE trimpot made for ?
Thanks,
neither of the two examples you show resemble the layout of the trim pots on my ModelD. mine has only one pot labelled osc sw and then a +10v adj pot and a _10v adj pot. It's easy enough to get an octave or two in tune but any more than that it goes out of tune. I can't find any calibration instructions that match the synth I have.
How do figure if mine needs calibration? The highest A is out compared to the lowest ?
I hope Behringer is doing their best to QC these before going out the door it makes me think that their is something partially rubbing against capacitators to cause this. So makes me also think these could go out sooner then expected.Also with the supply and demand and trying to get orders out the door and even new models being designed I really really want to put good faith Behringer is being thorough about quality. I bought a model D 2 months ago and still waiting it seems like every month they keep telling me the orders have been pushed back more so I’ll let you know how mine is with a follow up.
Is it the same for the pro 1?
Love what you have going here. Helped me tune my model-d. I am having trouble with the octave tracking, though. I've read the manual over and over and it just doesn't seem to be clicking as when I go to fix the octave tracking, the whole synth goes out of tune.
Any ETA on that octave tracking vid?
Did you solved the octave tracking problem ?
FYI the midi/USB adapter shown here (the cheap no-brand oval shaped ones with just a treble clef logo) don't pass sysex properly. I've ran into problems trying to transfer patches into a Korg FM2 with one of those. If you need to send the Sysex to reset the device and nothing happens, try with a better midi interface. A Roland UM-One Mk2 should do the trick.
but whyyyyy does it go out of tune in the first place?
@BehringerKnowledgeBaseOfficial Who dropped the ball in the over all design of The Behringer Model D? The reason why I ask you this, is there are other analog synthesizers out there, that have an external tuning knob on the surface of the unit for that same purpose of fine tuning the OSC's... Respectfully, having an external knob to tune each OSC should not of been that cost prohibited to stop your design to including those external tuning controls.
My understanding is that these type of trimpots have a very low cycle count (and are very fragile), can you give the cycle count lifespan of these components?
Also, In the manual it discusses Pitch CV calibration and Octave calibration before discussing Oscillator calibration...So I am wondering if an owner should first do Pitch CV and Octave calibration before attempting Oscillator calibration?
Behringer KnowledgeBase any solid answer as to when these synths are gonna be available thru guitar center ? The wait for these is quite ridiculous. Now we're waiting for the neutron too. Dammit ! Remember when roland came out of nowhere with their version se02?
even better,what happens if moog themselves drop a product to compete with this synth? That could completely ruin the behringer model d gameplan !
Behringer KnowledgeBase when is the octave calibration video going to be available Behringer?
how to do pitch cv calibration?
Does the screwdriver for the back have to be insulated?
I would expect they've recommended this just to cover their own backs in case you short something - basically you should be okay, just don't bridge any connections while you're in there.
The newer models had plastic trimpots anyway, so I really doubt you'd mess anything up!
@@gogogord It's more likely because your fingers transfer electrical noise, to a metal handled screwdriver, which affects the results, making it harder to tune.
Even the proximity of your fingers to the trim pot or the PCB may have some effect. Ideally, you should do these things with proper trimmer tools, which tend to be at least six inches long, so you can keep your hands further away.
@@TooSlowTube That's a really decent point. Would grounding your wrist help any?
@@gogogord I guess it couldn't hurt, but that's more for preventing static shock (ESD).
"Hand effect" is an inductive phenomenon - your hand gets inductively coupled into the circuit, and acts as an antenna, just by being close enough.
In a lot of cases, it won't make a noticeable difference - it depends on the circut - but it's worth bearing in mind when you're trying to set something precisely.
@@TooSlowTube Basically you don't want your synth working like a theremin while you're doing precision tuning on it - definitely a good point worth keeping in mind.
Thank you!
I tried this and quickly rounded out the plastic screws... I guess this is why they were changed in later models! What do I do now? Hope you can help :(
Would've been nice if they'd put the trimpots recessed on the back panel so you wouldn't need to open it up.
How often is this procedure required?
Do I have to do this with every Model D, or are new models already perfectly tuned from the factory?
Muss ich das mit jedem Model D machen, oder sind neue Modelle schon von Werk perfekt getunt?
Hello, at 1:20” can you please give serial number when the new version of model d starting?
Hi! Great video! In midi mine is in perfect tune but when controling it with CV/gate, it is out of tune. I like to use it with cv/gate because then it becomes touch sensitive, so do you think it would work tuning it without midi? Only using cv/gate? I need to adjust the octave range.
@ Behringer Knowledge BaseIs there any video for tuning the POLY D?
Does anyone know where I can find an inexpensive choona?
Greetings from La Paz, Bolivia!
🇧🇴 🤘🎸
I would like to know, where I can find your products here in my country?
On my Model D, the trim pots of OSC2 Range and OSC3 Range only go up to a G#5. I can't get them to reach a perfect A5 pitch. This way the whole synth keeps sounding out of tune. Anybody know what I should do? Tune all the oscillators to a G# instead of an A? For Range and Scale?
I just purchased the model D and I'm very happy with it. But I do have a question about the tuning going out while changing my pitch bend on my Roland controller, more that 2 % pitch bend. A full note. It seems to stay in tune by itself and when I pitch bend a bit. But for some reason my pitch bend wheel is set up about an octive and that's when I lose the tuning. It does go out a bit. Then I have to retune using the tuner but it's really way off. Anyway how can fix this? Thanks.
Easier than a Juno 106 and SH101 :-)
Thanks for your help :)
Is this the same for the other synths (K-2 and TR-2 specifically) My K2 is a little off and whilst its fine (I just offset the master) eventually I will want to recalibrate.
Behringer, can you please advise how to tune the Crave with the 2 small holes on the front panel???
hello , i bought the model d a few days ago and this machine is amazing ! :) i want to ask a question for anyone who knows the model very good ! i need to tune it when i bought it
immediately ?
instructions not clear smacked my model d with a tuna and nothing happened
is the same method used to tune the oscillator on the crave? if so, where should the oscillator frequency knob be set whilst performing the process, 12 o'clock?
Hello, my Neutron drits around 14 cents per octave...is the procedure to calibrate the neutron same as this?
oh my dear! I hope I have to open mine not that early ;-)
But glad that you should how to do it in case of!
VolcaRock hi there. How did it arrive? I'm expecting one next week :)
It's not really "opening" the synth. This is essentially a eurorack module that comes pre-mounted in its own rack. I would imagine quite a few folks re-mount this the moment they pull it out of its packaging!
I have aquestion concerning the Note Priority and the Poly Chain.
Can the Polly Chain also be used with a different (Polyphonic) Unit and Top Note Priority?
This would be handy in Live Performance Settings where a Single Note Lead would give you the Model D only and augment it with additional Voices from another unit (not doubling the Lead Voice) if you played a Chord.
The seyup would be a MIDI Keyboard (MIDI out) going into the Model D's MIDI In and a Polyphonic Module connected to the Model D's MIDI Through (to module MIDI In).
Have you tried anything like this?
The MIDI settings are on P.31 of the Model D. Owner's Manual.
does this work with poly d
is this for fine tuning and making sure it is roughly in tune over several octaves? I have a model D that for some reason the tuning got really wacked out and is roughly 5 semitones out, I have managed to correct this by downloading the synthtribe software and setting the midi transpose but I feel like I shouldn't have to do this. How out of tune should this synth get.
About how much tuning is available at the pot? My unit settles out about a fifth off. I play a C and get a G once it settles.
Is this applicable to the K-2? Mine is in dire need of calibration.
I'm trying to perform this tuning, and OSC 2 Range will only go down to a B5. Can you please help? Man I was so excited to use this synth and this is super frustrating.
I did attempt that, which is when I discovered OSC 2 will not tune below the B pitch. When I was referring to range, this is the process I was referring to, sorry. It seems to be 2 semitones off no matter what I do. I’ve followed the instructions step by step, and it just will not get to an A. I’ll submit a support request though.
@@BehringerKnowledgeBaseOfficial Any chance of that next video? It's been 11 months :) Apologies if it's up but I couldn't find it.
Why is this needed ?
How often does this need to be done, 10 hours? 20 hours? 50 hours? (of course I'm referring to the time the unit is being used, so 10 hours could be 2 months of usage).
is this works for pro 1?
The question is how often do you have to do this? Once a year, once a week?
Would be nice if we could tune the oscillators without having to open the unit. Maybe putting some knobs or screws in the back of the unit? Anyway, it's amazing what you guys are doing with these new synths. I'm anxiously waiting for the OB and the 101. :)
Maybe someone could come up with an aftermarket tuning method and clean up on that part of the market from overlooked engineering. Let’s push each other for more innovation!!
You cannot move trimpots outside of the case or even expose them to air - they shouls be same temperature as the rest of the pcb. We are talking micro changes in temperature. As long as environment is stable it should hold the tuning ok
I think the main reason is to have the tuning capability available when the D is removed from the case and mounted into a Eurorack installation.
Mine needed doing after two months.
Jesus, I added multi-turn trimpots to my '73 Minimoog in 1990 to make it easier to adjust and more stable. Why the mistake here?
Found a bargain price on multi-trimpots after first production run probably :)
Why Behringer?
I guess the price tag says it all really.
Good video! I'd like how to do with k2. Someone knows?
Please, I need help. I am a novice on semi-modular synthesizers (like is Behringer Model D here ). But I can't get any sound, except the A-440 reference tone. Does anyone know where the problem might be? It's the second BMD I've tried and it's the same - no sound in the VOICE switch settings. Thank you for your advice.
Perrymanx your probably have the filter closed, oscillator off, or sustain/decay off.. if still unsure, move a bunch of knobs until you start to hear something and then you’ll figure out what was wrong. My first time in front of a synth the settings were weird and I couldn’t get it to sound either lol
This is insane Behringer is suggesting this and letting non professionals open this up to tune. I can see these turning into a mess with very unpleased customers. Technically with Behringers outstanding warranty shouldn’t they allow me to send it back or take it to a registered Behringer tech locally to have them calibrate it correctly. Is this a option Behringer???
If you are struggling to follow these simple instructions then I hope you don’t drive!
I would like to see more companies give us schematics and let the users repair or modify your own stuff. Like in the "old days" as nearly every electronic device came with service manuals. Stand up for your Right to Repair!
I am a musician, not an electrical engineer. This procedure requires opening the synth and tools that not everyone has. It should only be done by a professional
I am sure someone will gladly charge an $70/hour bench fee to turn a few screws.
As a reader, I’m very unpleased by your comment. Try learning a new skill. You’ll find it’s quite simple really. If not, you could always pay a ‘professional’ a similar amount to the retail value of the synth to perform this simple task for you.
Can i somthing tune in my K-2 ?
I use to play out of tune (with all my gear), so that I don't hear false notes. No joke.
no firmware update for mac
In this tutorial I see only the way to do it within the older version.. why there's no explaination on how to tune with later version's "multiturn trimpots"? how to tune my "D" with those small blue boxes??
Hi Pietro - I have the newer version and followed the instructions in this video with no issues. The circuit board is labeled as to which "blue boxes" are for which OSC, as well as the RANGE and SCALE controls. Its easy!
I have one
This has to be done everytime ?? or just one time ?
nope do it a few times a year as they drift its not a digital synth
the osc 3 from mine model d is so of , its even more then an octave, can this happen? is it fixable by tuning?
Sebastian Feldhof flip the osc control switch
@@graxjpg
oh, one year ago... hehe... actually the osc was broken and I got a new model d. switching the osc control was the first thing I checked
Sebastian Feldhof haha I figured! To imagine if after a year you hadn’t tried that was so hilarious to me that I had to write what I did. Cheers to owning this incredible synth! I got mine about 6 months ago now. My first piece of hardware that wasn’t for guitar or stereo haha.
And so much easier than selling it with a tuning knob on the panel.
I'll stick to software.
I really need this video but for my Poly D. It's brand new and I tried to tune and made worse. Help!!!
I've calibrated my Model D three times but I cannot get Oscillator 2 to stay in tune, the other two track perfectly after calibration. Oscillator 2 will track well immediately after calibration but then will start to gradually go out, I don't have the patience/mental capacity to repeatedly tune it! Any idea on how to fix it?
been 3 months but yea it'll always go out of tune some way, just gotta accept it
Do other analog synths require tuning like this?
Yes, the vintage ones need an oscilloscope and in some cases a volt meter.
Not all of them. Many have pots of the back for tuning. That would have been much more convenient.
🙄"Sigh-sex"? Never heard anyone pronounce it that way. Being it stands for System Exclusive, you don't say "Sigh-stem" do you? so can't be a regional/accent thing
"Sigh sex"
Wow, even an employee is pronouncing it as "berinjer".
Exactly what I needed. Thank you!
