This is what it's all about. A regular, real-world issue investigated, dealt with and explained clearly and concisely. Starsky does these things so we don't have to. TH-cam gold.
Irony is that Behringer gets the clone right down to the most miniscule details - and people complain it's not as good as the original - because original wasn't "original" anymore
Thing is.. by raising the offset it raises the bottom of the range too.. instead of putting the cutoff at max, put it at min, and you'll see what the lowest frequency the cutoff knob goes down to.. So, to not affect the very low end; I tweaked that until there was some audible movement on the spectrum; which for me was 19Hz (sub box ofc).. that resulted a max high end of 18Khz; which is plenty high enough; beyond my hearing .. so basically; be careful you're not losing the ability to go down low enough!
The VC adjust screw only adjusts the resonance range to fit the range of the resonance knob - it doesn’t technically ‘brighten’ anything - it just shifts the tone to the right or left of center. That’s why the sound is off - not to ‘protect your hearing.’ You can hear the tone just fine at lower settings. Setting the range way over (not ‘up’) to 20k just cuts off the low end. I set mine to 8k to center it on the potentiometer. If your synth sounds “dull,” you might want to put the signal through an EQ with a little compression to liven things up. ☕️
@Starsky Carr I recognise that this YT vid concerns the VCF cut-off freq; however, did you ever manage to find an (unofficial) fix for the VCA bleed issue which plagues some of the Behringer MonoPoly re-issues? Mine has started to behave quite badly in this respect, to the point where I've temporarily fitted a (Behringer) noise gate pedal to resolve the amount of bleed!!!
Good thinking by Behringer to put the trimpots at the back like that. I tweaked mine up to 10kHz. Sounds good enough for me. I can't hear anything above 12kHz anyway :p
Nice job! On SOS there is a review/comparison by Gordon Reid and he too was fooled by his old Mono/Poly having the filter (mis)calibrated, fortunately he found some YT videos with the solution.
Interesting that the original Korg manual has this in it. I wonder if it really was intended that way or if it was simply a mistake in the manual and Behringer followed it, seeing as no originals have turned up yet with the calibration set to this limited range, as far as I know. But maybe there are original Korg units out there with the calibration set this way from the factory. I guess we'll never know. Anyway nice job on figuring it all out!
Cheers. Once I found that bit in the service manual I had to put it out there. I couldn't;t understand any of it... but did a quick calc and 7.1k rang a bell ;)
It's not a mistake and service manuals have multiple revisions. Seeing how many MonoPolys were repaired in the 80s it would mean they all came out wrong. Trust me if the service manual says 7.1khz it's just that. The compare with an original that is tweaked so much more open is not fair because it will sound much louder.
@@TheTerracide Okay, I believe you. But what do you mean with "will sound much louder". It's about the LPF cut-off. Volume levels have been matched otherwise.
Unfortunately mine is one of the first models that have VCA bleed 😢. Plus when I program patches they are sounding way different to the patch intended. I don't know what I am doing wrong although I followed everything according to the patch sheet.
I’d try starting off with a single sawtooth on one oscillator and and start building from there. You may have missed something in the patches so starting from scratch ensures there’s no modulation etc.
Thanks for this but I was being an idiot and twisted the VDA ADJ by mistake. Any idea what the default for this is and how I would go about getting it back there?
Sir, do you know if there's any SDK of the Behringer Mono/Poly to have some control it's components, over USB /serial instead of the having cc structures
I don't think it'll ever be possible as its been designed like the original in most aspects.. .all analog ()or mainly - can't remember if the envelopes on this are analog or digital).. with no digital control.
@@StarskyCarr Well there is level access to USB with the latest firmware you may choose MIDI-USB so , it also has a clock, my idea is that (at the least) there is some CC control overlay to reach the turnables. Let's ask beheringer
This is a fantastic tutorial man thank you. Got my MonoPoly yesterday and used this tutorial no problems. Do you happen to know how to get the MonoPoly to sync the arpeggiator clock to sync to a DAW. As in the DAW takes the midi clock time from the MonoPoly. Been trying to get reaper to take midi clock from it but getting no where. Thanks in advance.
I’ve never tried it that way round tbh. I’ve used the daw to control the MP sync and I’ve also used a TR606, but never the other way round. It sh out old be possible with the USB. Use the internal clock in the monopoly and then tell reaper it should be listening to an external clock - never used reaper either though!
A very minor amount.. check my other video where it's set a 7.1kHz... the bass response hardly changed.. Its s little higher now... only down to under 20Hz! So lower than you can hear, and lower than any sub. I'd have to double check again, but it's not worth it tbh... still shakes the roof.
Yo Starky, thanks for the vid, I have a question you might be able to help me with - I'm considering the MonoPoly or the Poly D - could you tell me what the differences are (if any)... I can't really seem to find a thorough comparison...
For me the main difference is the sequencer vs the arp... and the lack of Chorus/Distortion on the MonoPoly. I happen to prefer the MonoPoly - but that's probably because I've already got a Minimoog :) Both are very nice synths.
Anyone know a good guide on manually tuning from the back. I was successful with this, and really only noticed my hearing it going to 19khz or so. Just a bit of room, sounds great! However the master tune is off by 15% on VCO1, VCO4 10% out of tune. The rest are flat on. It’s a lot better quality control than the model d for sure. But it is a bit off here. Each VCO has Offset, Scale, Hi Trim in the back. So far no issues going up octaves at all, which is great. But I’m guessing the offset is going to be the tuning part to line it up to center...correct? I can live with it for now tuning it down with a tuner. But def want to fix this for accuracy.
You can’t EQ it to sound as bright as it does with the filter tweak. You can run whatever you like through your EQs to fit something in a mix, but it’s not necessary if it sounds Ok. I try not to and let the sounds fit naturally, but to stop muddy mixes especially in the low kids and bass everyone tweaks a bit.
@@StarskyCarr no I meant do I need the EQ to see what frequency I’m tuning it to. Can I just turn the screw however many times and trust thats its right or do I need the EQ to see exactly where I’m tuning it to?
@@333jobforacowboy aaah sorry that makes much more sense!! 😂 you can just turn it until you can’t hear it really. It’s around 20 turns all in all. But the EQ is really easy if you’ve got a DAW just input to a channel, put an EQ on there and make sure monitoring is on.
@@333jobforacowboy hey bro,did you ever do this to your monopoly? If so,did you just turn it up without running it through anything and how many turns did you have to do to get it brightened?
We need to go deeper... :P I looked at service manual for Korg Polysix (machine from same era and using exactly same filters) and they are stating there, that open cutoff with full resonance should be calibrated between 19-24KHz. So I kinda suspect that Mono/Poly service manual might have print mistake there (and original Mono/Poly's like the one you have tested are simply calibrated from factory to correct value - around thoose 20KHz).
Haha OMG where will it stop 😂 it does seem odd that Korg was happy at the 7.1kHz. But then I’ve no idea what I’m doing - as soon as the manual mentions voltages and oscilloscopes I’m out!! All I know is the numbers make sense.
If it was a printing error, surely Behringer would have noticed 7KHz sounded very different than the originals they used as an example to model their remake to?
Wow, didn't see that one coming... Still weird though. I can't imagine so many original Mono/Polys were modded that most people think that's how it was supposed to sound... And what about the keyboard tracking that hardly does anything with the 7KHz setting?
The filter tracking is strange, but I managed to get it tracking in the unboxing video... not sure what was going on here though. Although I was concentrating on the frequencies so didn’t give it much attention.
you were at 9khz when you started going up again, so maybe 30 turns-ish :) for me personally, I'd keep it at Korgs tuning suggestion for authenticity :D not that I'm qualified to suggest such a thing as I only own a td-3
Haha... I know I couldn't see the screen - the sun came out just as I started tuning so I was blinded by the reflection :) It's odd though... after you've heard it bright, it sounds muddy with the original settings. If you want it to sound like the original just don't put the cutoff over 8... and watch the key tracking. Interesting that no-ones come forward with a dull vintage one yet. Seems this was a pretty common tweak.
haha I always get a thumbs down within seconds on anything Behringer related.. almost before anyone could watch the intro to see what its even about :) Seems like someone doesn't like any mention of them on TH-cam. ??
7k is way too low, the service manual is likely wrong and has nothing to do with how the factory setup units. Service manuals were made months after production started to enable service repairs. The Poly 6 with the same filter chip is set up at a much higher cutoff.
I noticed a difference in tonal quality when Korg overhauled their VST a few years ago compared to when it first came out in the 2000s - the updated one had more “sizzle” compared to the original moodier sounding one. I wonder if the difference was also that the filter was tuned (virtually) to the different frequencies for each version.
You are using and electricians screwdriver. NEVER DO THIS. The metal conducts radio waves which interfere with the tuning. If you want accuracy, you need a non conductive plastic screwdriver; if you are a Moog person, a "wooden" screwdriver. (I kind you not!) Radio waves will affect the tuning of the micro pots on any analogue synth. Really SC, you should know much better!
I have checked and it was a typo. It looks like a 7 but it was in fact upside down and was supposed to be a letter L, meaning "Loads" as you were supposed to set the frequency really high. Easy mistake to make.
This is what it's all about. A regular, real-world issue investigated, dealt with and explained clearly and concisely. Starsky does these things so we don't have to. TH-cam gold.
High praise indeed. Thanks, it’s appreciated.
Nobody would care about it if it was in the manual, they would just go to TH-cam and watch your video… So thank you for doing it
Starsky, thank you for always being so positive and transparent in your videos - it makes them a true joy to watch!
what a fantasic video. I dont even own this but got stuck in watching the whole thing. Very interesting bit of information.
Still watching the synth vids then ;)
I really like these unbiased and really confusing reviews. :D
You sir - are a living legend, almost went back to the shop as initially found the Filter dull as f*ck.

Good point
if only you could add comparison sounds between the 7khz and the 25khz with full sound and modulation and reverb to compare the style of each other
NCIE MAN... mine only went up to 19.1K but that will more than do, thanks for this easy to follow video!
Thanks for the info! I finally just got mine in the US yesterday. Finally getting a crack at it tonight to really dive in. This was very helpful!
Glad I could help!

I'm wondering what the LFO-1 calibration options on the MS-5 do, because the linear response of the rate slider is odd compared to LFO-2.
@Starsky Carr I recognise that this YT vid concerns the VCF cut-off freq; however, did you ever manage to find an (unofficial) fix for the VCA bleed issue which plagues some of the Behringer MonoPoly re-issues?

@@StarskyCarr :-) :-) :-) :-)
Great tip!
Could you please share the service manual? It's not on Behringer's website unfortunatly.
Hi! Have you tried adjusting things on the MS-5 yet? Like the LFO rate or even things related to the envelopes perhaps?
No, I’ve not tried it versus an original. I know one that’s being renovated that should be a good benchmark.
@ I was more thinking along the lines of ”improving” LFO rate etc :)

does your model note bleed too? i mean - mine hangs last played note very quietly, as if the gate didn't close completely
Would that be affected by the EQ Intensity?
I’m a little confused, does the cutoff knob have to be all the way open or closed when tuning?
Open - if it’s closed you won’t hear anything
@@StarskyCarr right, good point haha. Saw it in the middle position before you started to show the tuning process, so wanted to make sure. Thanks!
