Eurorack low pass gates - session 5 (ish)

video upload by John Schussler

Note this is the first post to feature BeepBoop.

"I can't stop collecting low pass gates. There's GAS, and then there's LPG GAS. Don't know what the deal is there.

Here's the latest batch. Most of them are small and passive, but some are bigger and powered and covered in knobs and sliders and stuff. So it's really a sound comparison, not a full module comparison.

Sound source: Befaco Pony square wave. Sequencer: Stochastic IG.
No envelopes, just gates out of the SIG.

Tube Distortion In 16hp - Rabbit Hole, Saevitum, Turbo Entubulator

video upload by John Schussler

"I have a 16hp hole in the rack waiting for a tube distortion. Which one do I choose?

Here are three options. There are more at this size, but I happen to have these three.

As it turns out, they're all very different in sound. The Turbo Entubulator specializes in flexible tube tone. The Rabbit Hole heads towards tube-y corruption while still staying somewhat civilized. And the Saevitum, well, it's just angry angry angry.

So I don't really have a choice so much as a selection for rotation, I suppose.
But it's interesting to hear them back to back and really get a feel for the differences in their character.

Input audio was a basic sine wave from a Dixie II+. Sequenced by Stochastic IG.

Note this appears to be the first post to feature Apollo View and their Rabbit Hole. The Saevitum by Abyss Devices, and Turbo Entubulator by Epicycloid have been featured before. That said, here's some info on the Rabbit Hole for the archvies, followed by a DivKid video.

Packed to the brim with character, Rabbit Hole is the first module by Apollo View, combining facility as a mixer with four stages of saturation and distortion, provided by both tube and solid-state circuits. With two channels labeled A and B, each offers an input VCA with Gain control and control voltage jack. Channels are summed before hitting the Drive circuit, a solid-state design with hard-clipping tendencies at extreme settings, then moving onto the starved 12AU7 tube section. For truly searing patches, flip on the OWTH switch, short for "Off With Their Heads", and make heads roll with a diode clipping circuit. There's also voicing switches for the tube, feedback capabilities, and the option to expand the number of inputs with the Curiouser module. Grit up your patches with Apollo View's Rabbit Hole.

Tube distortion fun, patch hacks & VCA tips // Apollo View Rabbit Hole & Curiouser

video upload by DivKidVideo

"Here we’ll explore making the most of distortion, exploiting tubes for interesting behaviours such as sub harmonic tracking as well as explore lots of VCA and mixing tips for things like building crossfaders out of VCAs. We’ll be doing this while demonstrating the new Rabbit Hole and Curiouser modules from Apollo View. Rabbit Hole is a Eurorack VCA summing mixer with multiple drive stages and tone control and Curiouser is a dual vintage VCA that can be used as an input expander or used standalone."

Abyss Devices - Tube distortions compared

video upload by John Schussler

"Abyss Devices makes a couple different tube-based distortions. The Saevitum is bigger, with a resonant LP/HP filter attached, and Saevicus is smaller with no (resonant) filter. Both use 12AX7 tubes and similar amp circuitry, so I was interested to see where their sounds differed or were the same.

Since the Saevicus doesn't have a resonant filter (it has as filter, but it serves mostly as a simple tone control), I focused on the distortion sounds from each module, with my main question being whether the smaller Saevicus was missing anything in that department, or whether it was just as growly as its big brother.

Input audio was a basic saw wave from a Doepfer A-111. Sequenced by Stochastic IG. Envelope by Zadar.

62HP Eurorack Drum Machine - House / DNB / Juke Beats

video upload by Perfect Circuit

"Our next 62hp adventure is a tribute to the driving rhythms and beats of dance-driven electronic music, spiced up with the fun of patching that can only be found on a modular system. Tubbutec’s new 6equencer adapts the classic TR-606 workflow into the open-ended Eurorack environment, allowing any synthesist to compile their favorite modules in the drum machine of their dreams.

Armed with some of his favorite drum modules, Wes breaks down some classic drum patterns and explores how they can be expanded and turned upside down within a patch. WMD’s Crater and Tiptop Audio’s HATS909 provide dependable kicks and hi-hats, while Qu-Bit’s Surface, the Erica Synths Sample Drum, and WMD Fracture help to expand the sonic vocabulary beyond typical drum machines. We’re also using the RND STEP from DivKid and SSF and Doepfer’s A-145-4 (mounted in in the 1U row with a handy adapter by Abyss Devices) for parameter modulation, and Befaco’s Stmix as a mixer.
