Behringer 121 Dual Filter Module
HTML-код
- Опубликовано: 30 июл 2024
- In this video we dive into the most important sound shaping tool in subtractive synthesis: the lowpass filter! And even better - two lowpass filters, since the 121 module from Behringer recreates the original Roland System 100m dual VCF. And because filters are awesome, this video shows a few more of them.

A lot of people don't explain how the high pass filter on this design works. I figured it was in series with the low pass, given my experience with the Malekko Roland version, but very few places anywhere actually say that much less give the signal path. Thanks for the great video with excellent explanations and examples!
These videos are fantastic, you really know how to teach concepts and practice all in one! I have been thinking about getting into modular for awhile now but worried it was over my head, turns out I just needed to find a good teacher!
Just another thank you.I have a rack that has several Sys100 modules that I put together, somewhat blindly, from an inheritance. I am still learning it's capabilities, and our in-depth videos have been indispensable in my journey. For example, your "Behringer 150" video led to about 8 hours of patching fun. Thank you!
Behringer did a solid one with this series.
A nice trick is to patch one of the outputs of the filter back to itself to both the audio and CV inputs. Those 2 signals could also be sent through and LFO controlled VCA for some more dynamics. Move the attenuators up for the 2 signals. The filter starts to crackle, pop and distort quite nicely, reminding perahaps of some guitar amp. Once again, the multitude of outputs and inputs make that an easy patch.
Very nice in depth review of this filter ! I've been messing around with Behringer system 100 modules for 3 monthes now and God I love them !
Nice! That's an awesome system you have there I had an original 100m system back in the day but only 6 modules.Loved the dual filter 👍
Thank you so much, you give me a helping hand to buy modules for the system 100. Your vid's are the best on youtube. Detailed, on the point and very comfortable to view (without this fx and hard cut nonsens). *FAT THUMB UP*
This is a very well done video - good editorial work, well filmed and edited. Wow!
I got the synth voice module that also has that filter (without the highpass tho, but dont need It anyways) and i have to say that i LOVE the sound of the filter with no resonance, It just sounds so pure and good, perfect for those filtered bass sounds or plucks.. defenetly a keeper!
the rez @ 18:00, nice.
why do i feel guilty for liking some of Behringer's Eurorack modules such as the 121?
I'm focused on building a complete 2500 series modular, but this video is now making me want to build a 100 series modular now... lol
I had this problem too and end up with both. Guess thats inevitable once you're into modular...
I have a euro system and this filter, I think it’s a complete bargain and sounds great
High peaks like the Matterhorn
The resonance is a real ear ringer
Very nice walkthru indeed.... please don one on the 130 as well, would love to hear if and how it overdrives ! Many thanks in advance!
Will do!
@@synthesizer83 looking forward to !
