It's been my pleasure. It's been fun making them. I've been pondering the idea of creating a channel dedicated to demo eurorack modules. Don't have the proper video gear for that just yet.

So I'm really curious about more details in the TITO modes; The manual states that SM is self-modulation and XM is cross modulation, but doesn't explain more than that.

My first guess is that in SM mode, each core is modulating itself while in XM, core 1 modulates core 2 and vice versa? It's still a guess. Would love some info on these

BaloErets, yes, your guessing is correct. The main idea was to mimic somehow the phenomena taking place in diode ladder filters within a state-variable design. The "chirping" effect of the 303 comes from interactions of filter poles due to nonlinearities in the ladder, which yields a little modulation of frequency. The XM mode in Belgrad is particularly interesting as it clearly introduces a strongly chaotic behaviour of the oscillating structure. Try it on some base lines ;-)

Thank you for taking your time to make the demos. Have fun with your Belgrad

And thank you and your team for bringing us such a gem!

The TITO modulation is fantastic, esp. when the Belgrad is being used as a VCO. Span modulation works almost like a pseudo FM Index. Had tons of fun with it this weekend.

Curious, what does TITO stand for?

So many Titos! Or is that Titae? What is the plural of Tito?

haha, too funny guys! Brushed me up on some of my Yugoslavian history! I was really thinking in the audio mindset and being it was named for different modulation options, I was sure that TITO was "T...... Input T...... Output.

Pardon my ignorance

Just picked this up today from Control - what an incredible filter. The range of tones this can cover is really unique and kind of hard to believe. I really think sonically and feature wise XAOC knocked it out of the park.

there are two small things I don't like about the module: the audible thump you hear when you change the modes with the dial, and the quality of the dial pot's feel. It's kind of light and insubstantial relative to my other modules and it's not like this filter is cheap.

Small complaints though, this is a keeper. Fantastic module.

Thank you! It's heartwarming as it took us a year to develop and tweak that project. Enjoy!

Well, we had a seriuosly hard time finding a rotary switch that has as much as 10 positions, is readily available in decent quantities, has the right body height and finally - that doesn't cost bonkers. I agree the feeling is not the greatest but these switches are very reliable parts made in Germany (and you can find them in some other euro modules from Eurpe as well).

The thump is quite a normal thing when you switch signals like that. It can be addressed only by adding some extra circuitry actually, which would be problematic as the PCB layout is pretty dense already. Plus it would surely drive the price up a bit which we wanted to avoid.

I noticed the thump during the sweep demos, and since one of my favorite filters, the Frequensteiner, does the same thing, I'm not too worried.

So after a 2 weeks with the Belgrad, all I can say very confidently that this is a killer filter. Each time I finish an evening playing with it, I appreciate it's design more and more.

A quote from the manual;
"Most of the settings are highly dependent on each other, so we encourage wild exploration to discover a plethora of sweet spots and ranges between the filter modes and resonance configurations".

I could not have said it better myself. Between cv control (with attenuation) over the space between the 2 peaks, a cv controllable balance between the filter's emphasis, the plethora of filter modes, AND the cross/self modulation... I keep finding these insane sweet spots. And not just "spot" spots. I'm talking areas where you dial in, and then have a full filter sweep beyond anything I've experienced in a Eurorack module so far.

Bravo Xaoc. The only place where I could offer improvement is that you didn't hype this one enough

. And saying so, I couldn't say how much I appreciate manufactures that don't hype their products. But this one deserves the hype.

It's the Batumi of filters

BaloErets well said!

Hopefully an up-coming video from me can really hype this thing up

... I have one by the way thanks to XAOC and it's great. As is the new phaser.

Please stop the hype; I want to buy one in the New Year and if you keep hyping there will be none available!

droningspaghettimonster · Wed Nov 30, 2016 7:02 pm

the resonance is so electric that i thought for a moment that it would roast my brain. im having hard time cheking out other than the first three lowpass responses because what ive got going is simply too beautiful.... this thing is genius.

Clearly we're not so good at spreading the hype. Actually we recently started to abhor all that "teaser" and "hype" marketoid horseshit. Still, we totally suck at quite indispensable things as video demos etc. Hope to improve ASAP.

We're really happy reading your comments here chaps. Belgrad's development too us quite a long time, because we wanted it to be as exciting as you see it now.
