Skull & Circuits METAL-O-TRON / first moments / modulated by Vox Machina LEO LEO sequencer

video upload by BRiES

"A while ago I acquired this nice METAL-O-TRON by ‪@skullandcircuits‬ which instantly proved to be a treasure trove of ringmod and other timbres. This video is me firing up the module for the very first time, so it's really nothing more than just a first exploration (but I always find it fun to record). I hope you enjoy this short video (more to come).

In the meantime I made a thorough deep-dive on the module that you can watch here:" [see this post]

Skull & Circuits METAL-O-TRON II / extensive playthrough / metallic percussion and beyond

video upload by BRiES

"METAL-O-TRON 2 by ‪@skullandcircuits‬ is a 16HP module built for creating stereotypical XOR logic (ringmod) metallic and noisy percussion (think 808 hihats), but in this deep dive video I try to demonstrate that you can do much more with it. There's a general introduction, a deeper dive and a pretty long section with a few (in my opinion) cool patches explained in much detail."

Sherman Filterbank vs. Skull & Circuits VCF-4 / a quick comparison (Standalone vs. Eurorack)

Skull & Circuits VCF-4 was announced back in 2023.

"A quick comparison of the Skull & Circuits VCF-4 with the Sherman Filterbank - good times all around.

Skull And Circuits VCF-4 Switched Capacitor Filter & Metal-o-tron Metallic Percussion Modules

As if there are not enough filters in the Eurorack world. Yet, here it is, something new. A dual switched capacitor filter, equipped for CV on all the things. A dual filter core no less for stereo use or for all kind of serial filter configuration shenanigans.

VCF-4 is a unique filter in Eurorack land. It’s a switched capacitor design with a lot of bells and whistles, offering a unique sound and flexible sound-scaling capabilities.

2 x 12db switched capacitor filter core
Sweepable LP/BP/HP Mode
+BP/-BP adjustment
Self-oscillating filter
Filter linking ( 1:1, octave down, 2 octaves down )
Serial or Parallel setup possible
Resonance CV control per filter
Filter mode CV control per filter
2x Cutoff frequency CV control per filter
Big fat knobs ( 20HP )

It’s one of the modules I use a lot, so I thought it was about time to get rid of the prototypes I have in my rack and build one that looks more like the real deal. I’ve taken all good things from the first 2 versions, ditched all the bad stuff and add some new stuff. That’s a lot of stuff.

In short, It’s a percussion sound generator, with a focus on metallic sounding percussion. Cymbals, hihats, tin cans, gongs, cowbells, … you name it, it’ll do it. It doesn’t really stop there, it’s able to create quite some unique sounding percussion elements, as well as some interesting drone textures. So it’s quite a versatile thing to have in your rack.

So, how does it work. The basic sound properties are generated by 4 square oscillators going through a logic XOR gate, combined with a noise generator and external inputs. The whole lot goes through a filter to shape the frequency properties and then through a voltage controlled amplifier – still following? I’ve drawn up a little schema to clarify the whole lot a bit.
