XAOC Devices - Belgrad

[@eyesintheskies]

Was hoping to limit my dalliance with eurorack by only buying filters to process external audio, it turns out I was a fool to think so 😂 This one’s sounds awesome!!!

[@DivKid]

Belgrad is indeed fantastic.

[@eyesintheskies]

@@DivKid having done further investigation I think I’m steering towards the Zagreb to keep my rig stereo, but the Belgrad is certainly a very unique & intriguing design!

[@scottgodon-decoteau430]

Just when I thought I knew which filter i wanted, here I go stumbling into this beast. Another awesome overview as usual. And to finish with some epic drum sculpting.... BANGING!!!!

[@DivKid]

Nice one Scott, there's plenty of filter videos on my channel if you need me to mess with your decision making some more! haha.

[@catchthehare]

Thanks for the brilliant overview. I love my Belgrad and this has opened up some more ideas. Very classy. 👌

[@DivKid]

nice one, glad to be of assistance.

[@jonaseggen2230]

I say the same two years later : ) At 11:30-40 I got an epiphany : D

[@precarious333]

Wow, such a unique filter. Great overview!

[@DivKid]

thank you

[@walrtbstudios5430]

I had, then sold, a MN QPAS. Sort-of regretted it later, but then I saw this- smaller, twin-peaked, way more options and a deal more vicious-sounding. Sold!

[@DivKid]

they feel and sound very different, glad you found the one to suit you

[@wackenthaljef]

...Look at those beautiful modules!!!!...

[@DivKid]

:)

[@AgustinDavidF]

I have just bought the Belgrad because of you review, just what i needed to hear. Great as usual. Thanks, my fried!

[@temporoboto]

Just ordered from Perfect Circuit, thanks to your demo! Can't wait.

[@vibratemutate]

i think this will be my first filter in my first eurorack, lots of options ;) hello modular world ;P

[@DivKid]

Hello This Weirdo welcome to modular world! :)

[@Endlesstraveler8]

@@DivKid and i think mine as well !

[@theelephunt]

awesome review. I love messing around with the Belgrad. I havent thrown an envelope on the FM mod yet..really like the way that sounds!

[@DivKid]

definitely a nice patch to exploit the filter with.

[@ellopropello]

wow, what a monster :) already was on my radar but this makes it 100%

[@DivKid]

Hey Ello, yeah it's a very good filter and character/drive type module. XAOC Devices do good work.

[@TomFrajer]

Thats exactly the kind of filter I was looking for, thanks!

[@kr61ab67]

Absolute great filter, and an absolute great demo too !

[@VictorSteiner]

The coolest filter I could find and was not dissapointed :)

[@DivKid]

nice.

[@michaelmazochi]

I finally grabbed hold of my poor wallet and grabbed the belgrad today after watching this again and I’m completely in awe of it. Pretty sure I’m annoying the neighbors. Cheers!

[@DivKid]

Anyone neighbours banging on the wall yet then?

[@michaelmazochi]

DivKidVideo if it were to go down that dark path of neighborly aggression I have dual resonant peaks on my side. Auditory WMDs. Ha!

[@killahkay2112]

What a Beast !!!

[@DivKid]

absolutely.

[@uaca_uaca]

Thank you so much ! Amazing, I buy NOW !

[@DivKid]

thanks, enjoy it.

[@HousePlant_Ambient]

It is a bad ass modular. Have it, and although expensive, very well worth it.

[@srmone11]

Killer review, like always

[@DivKid]

thanks, I appreciate that.

[@BURG]

this sounds completely bonkers ! wow

[@DivKid]

:)

[@nchemil]

Thanks a lot for you video. Very inspiring 💡

[@DivKid]

Cheers Nassim

[@pantalalabs]

woooowwwwwwww delicious sound

[@DivKid]

cheers

[@naught101]

The input sound in that first example looks so damn cool on the oscilloscope. Is that left-right movement some kind of sync effect?

[@faruambient]

great video, thanks for this! Which filter would you recommend for heavy drones and ambient pads?

[@VJFranzK]

9:05 Mode 9 and this module in general have a more "vocal" quality than the average filter. Will have to add it to my list! B - )

[@RobertMRyder]

If you could only have the Belgrad or the Filter 8, and price wasn't a decision factor, which would you prefer? Alternatively, how would you use them together?

[@ekoboydj]

i was sold in the first 3 min. ridiculous filter

[@dynamictechbass2582]

Awesome Filter.

[@DivKid]

yep

[@dynamictechbass2582]

😀😀😀

[@dynamictechbass2582]

I m looking forward to the prototype Odessa soon

[@WhiteWulfe]

Well now, hello oh so interesting filter... Definitely some unique stuff coming out from these guys.... Out of sheer curiosity, what did you wind up feeding the filter with oscillator-wise?

[@stateazure]

Damn this filter sounds crazy good. If you still have this + Kamieniec, would you consider doing your next E370 patch through these two? or just though this filter? I can only imagine how amazing the E370 would sound going through these puppies.

[@DivKid]

I do still have them both here. Please keep reminding me on the videos that you'd like to see it. Next video will be more of a proper demo showing off a function of the E370.

[@stateazure]

I'll do that, looking forward to the next one!

[@markmccarthy3304]

Can't decide on this or the dual Borg or the morgasmatron, any thoughts?

[@DivKid]

All sound pretty different. So if you can look beyond the feature differences go with whichever tone you prefer.

[@jasevaughan7829]

Looks like a decent filter

[@DivKid]

absolutely is.

[@piotr803]

15:50 Lush review, Ben. Q - Is the filter inverting the audio phase?

[@DivKid]

yeah looks like it.

[@DivKid]

and thanks

[@GuitarsAndSynths]

This would be super awesome with Odessa!

[@laptopolist]

Another inspiring overview! A quick question... I noticed that the Belgrad's output appeared to be inverted on the Mordax Data compared to the input signal. Is that the Belgrad's doing or something else in the chain? Thx!

[@pe00000001]

Note that it depends in particular response. In general, all analog filters introduce phase shift that depends on frequency. It usually starts from zero at the lowest frequencies, reaches 90 deg at the cutoff point and is 180 degree above the cutoff point. That's where the inversion comes from. Hence, if you combine several responses (like in Belgrad) you have a combined effect of these phase shifts, depending on what mode the cores are in a particular configuration.

[@laptopolist]

Thanks for the reply. I understand that there will be phase shift, but in this instance the Belgrade signal was 180° out of phase throughout the demo, with offsets from that created by the processing.

[@pe00000001]

Srlsy? I can see there is no phase inversion at 14:16, 14:23, 14:30, 15:00 ...

[@DivKid]

Hey Matt and pe. pe is spot on, there's several points where's there's no inversion. There's lots of modules that actually invert the output without us knowing. For the most part when it's audio we don't realise

[@HiddenCaterpillar]

Honestly really hard to hear the basic character of the filter when your input is that terrible noise. Why not just sweep a saw?

[@thomasberner5282]

Like it has been done in the old days... 🤣

[@theinternetseekers2436]

Is this an OTA filter at its heart?

[@DivKid]

not sure.

[@station2station544]

After tinkering with this filter for a while, personally, do you find it's SEM-esque, or more like another classic you know of? Or completely new?

[@DivKid]

Sounds like something new to me with all the options it has I haven't thought of it as based on anything particularly. I'm sure XAOC devices will discuss the core circuit with you if that's of interest.

[@station2station544]

In many demonstrations I've picked up the SEM quality. (which is a synth which employs the state-variable bandpass filter). You'll hear that quality here: kzbin.info/www/bejne/j3y5gpd6n7Srobcm34s (specifically at that 1:34 mark if that didn't auto-place you at that spot). Regardless, I have ordered one! Thank you for your video as well. Thumbs up

[@Waldemar_la_Tendresse]

Interesting filter, unfortunately some opportunities were given away. For example, it is not understandable why there is not 2x resonance control for the two different filters. This would have made much more possible in terms of sound. Great video as always.

[@pe00000001]

There IS dual resonance control, so you can have the two cores with different degree of resonance. This is what Balance does.

[@ekoboydj]

Div how u get synced LFO there? 14min fiddle

[@deviousxen]

SOMEDAY.

[@DivKid]

hopefully that day will come.

[@icondetach3870]

The mode selector seems awfully wobbly, could this somehow be improved or fixed?

[@JahTMT]

It is not really wobbly when used, it doesn't feel very solid but after a year of heavy use, it's still right in place ;) besides, you're not going to tweak it like crazy while playing because of the "clicks" generated when changing the modes... (unless your music is compatible with clicks of course !)

[@Vadlife]

What module (oscillator) do you use to filter with Belgrad? (5:28)

[@DivKid]

it's a mix of a few things, analogue VCO, E352 and some noise by the sounds of it. Clipped in parts through a CP3 mixer.

[@TomFrajer]

@@DivKid haha, loove Feedback stuff, PRE-CR is amazing :)

[@BrokogSindre]

What kind of kit/oscillator are you using for the base sound going into the filter?

[@theinternetseekers2436]

You can see he is using a Clouds Terranium E352 in the video

[@BrokogSindre]

True that.. i realised it when he zoomed out... about 20 seconds after i wrote the comment :D

[@theinternetseekers2436]

Divkid always seems to use a wavetable oscillator for his demos, and i must also admit, i have thought the same before and asked, he used braid in a lot of his videos but this cloud terranium i must say is the business. I just got a Verbos Harmonic oscillator that i'm not loving as much as i thought i might, maybe its time for me to get a digital modules instead of my analog tendancies lol!

[@nectariosm]

I was going to say in the beginning that this Belgrade demo sounded a bit "cold", but that was the oscillator used. Still a briliant filter and a great video showcasing the module.

[@DivKid]

Hey all, the first sound is a mix of all sorts, some analogue oscillators and some digital. The second bit with the saw wave is the E352. I use wavetables and digital oscillators for demos as they're just super handy sources to have to make things quickly. If I want some sort of DX style FM that's wave folded to make a bass line to then run through a delay I don't want to spend an hour patching that up before turning the camera on for the demo.

[@WearySisyphus]

it feels to me that 90% of the sound you get here is coming from your oscillator and not the filter

[@DivKid]

in which bit? The filter drives and saturates and then of course filters. So that's the majority of sound shaping going on.

[@SymbolicStudios]

Yeah I was thinking the same thing. Would be good to let us hear the source sound before going into the filter so we can have a better sense of what it does outside of the obvious.

[@MadelnMachines]

I know what you mean. Is it just a standard saw or sine going into it. Turns it into some crazy nasty wave shaped thing like a really nasty digital wavetable.
