Roland Juno Chorus eurorack comparison

video upload by John Schussler

"I'm a big chorus fan, and am continually surprised there aren't more of them as stand alone modules in Eurorack. The most famous chorus was originally shipped in the Roland Juno line (6, 60, and 106), and is what's replicated in these two modules I'm looking at today.

The Feedback Chorus 106 has been out for a while, and is now discontinued because they can no longer get some of the NOS (new old stock) parts they use.

The SoundForce uChorus is brand new, and has substituted an STM and some other new bits to make up for the MN3101 driver IC that's no longer available.

Both are following the original circuit behavior as closely as possible.

I compare them here to see if one is better than the other.
Spoiler: I can't hear the difference. Can you? Let me know in the comments.

The G-Storm electro Feedback Chorus made it's first appearance here in 2019, and the SoundForce uChorus in May, 2023 this year.

SEM vs SEM - November 2023 edition

video upload by John Schussler

"The G-Storm Electro SEM VCF arrived the other day, and I figured I'd give it a listen in comparison to what, up to this point, I think is the best SEM eurorack module: the Studio Electronics SEM VCF.

(Spoiler alert: The G-Storm gives the SE a serious run for its money)

I've also thrown in the Bubblesound SEM20 and an AMSynths Obie XA. The Bubblesound is mostly SEM, but with some MS-10 bits grafted on that makes it more aggro. The Obie XA isn't a SEM at all, different chip, but is also modeled after an Oberheim filter so I figured I'd toss it in for contrast.

VCO is a Befaco Pony, first on saw then on square. Sequencer is a Clank Chaos. Envelope is Zadar.

Be forewarned: a lot of this video is me going back, and forth, and back, and forth, and back and forth between modules. Don't get seasick.

Eurorack granular synthesis module comparison

video upload by John Schussler

"I've had Beads for a long time but have never really gelled with it. More recently I've acquired Brinta and Mojave, so it seemed like time to come to grips with granular in general, and these modules in particular.

This is a *very* basic comparison based on me reading through the manuals and spending time wiggling knobs. Each module gets a first pass using a simple Pianophonic sequence, then some time with a more complex audio source using some acoustic material from my last CD, 'The Willow Ladder.'

(Available on Bandcamp at, I will note. Nudge nudge.)

I'm really just interested in seeing which one gives me more interesting results with less RTFM'ing. I'm not sufficiently impressed by granular synthesis in general to really grind through any opaque interface designs.

SSF Steady State Gate vs Erica Synths Black LPG: Listening to resonance

video upload by John Schussler

"A recent thread on ModWiggler brought up the question of resonance on low pass gate modules, and it occurred to me I hadn't really compared the Steady State Gate
from SSF (which has resonance) to the Erica Synths Black LPG (which also has resonance). Resonance isn't wildly common in LPGs, so it seemed worthwhile to listen to both and see what differences I heard.

Yes, there are more LPGs out there that include resonance. I don't have them, I just have these. Yes, they're very different modules with different feature sets, but I figure the resonant part can be examined somewhat separately from the rest.

Maybe not. We'll see.

VCO is a Befaco Pony. Sequencer is a Clank Chaos.

Clank Thererec 2-channel eurorack cv motion recorder

video upload by John Schussler

Announcement post with pic here.

"There are quite a few cv recorders available in eurorack, including a few that use motion or pressure to indicate gestures. Clank has now released Thererec, which uses proximity sensors to sense your finger motions, and coupled that with recording functionality to loop your gestures.

The name is derived from its inspiration, the theremin, bonded to a recorder.

Where it gets more interesting is in the ability to change the range and speed of the looped gestures, plus a reset jack for syncing to a clock.

Source audio is a Befaco Pony VCO.

Making Sound Machines - Farbshaper

video upload by John Schussler

"I covered the Making Sound Machines Farbfolder in a previous vid: [below]

The Farbshaper is similar, but not such a standard wavefolder design. It has a gain circuit that's unusually responsive to the amplitude of the input signal, giving it a very organic sound and variety of timbres you don't get on other folders.

The input signal is all sine wave from the Befaco Pony VCO.

Making Sound Machines Farbfolder vs. Joranalogue Fold 6

"Just got the new Farbfolder in from and put it together (it's an easy build, just knobs and jacks). I must admit the sexy color LEDs at the top caught my eye. They've 3D printed a light guide and used a transparent panel, so it gives you an excellent show of das blinkenlights. (Die? Das? I've forgotten what little German I had.)

But of course there's always the real question, how does it sound? And how does it compare to others at its size? I figured I'd pair it against the Fold 6 from Joranalogue, which is also 4hp, for a head-to-head.

Patching Panda Punch MG - first patch

video upload by John Schussler

"I'm not entirely sure what to call the Punch MG. It's a mixer, it's a VCA, it's an envelope, but also it's none of those things. It's its own thing.

Try this: you put some sounds into it, plus some triggers. It has a decay envelope for each channel that you can adjust so that you can make those sounds percussive. That's part one.

Then you add each channel to the Mute group (or don't). This doesn't really mute the channels in any sense, it ducks them. The signal on one channel affects the envelope of the signal on another, and vice versa.

At least I think that's what's happening. In any case, it makes a group of sounds work really well together.

End of chain drum effects

video upload by John Schussler

"I recently got the ADDAC Vintage Clip, and have been playing with it as an end of chain drum mix treatment. I have a few other simple stereo distortions and filters and figured I'd listen to them as a group and see which I liked best in the role of 'final drum effect.'

It's not so much a fair comparison as...just a comparison. There are lots of other modules that could probably serve this purpose just as well, but these are what I have and wanted to listen to. So there you go.


Drums are an SSF Ultra Kick, Prok SN, Prok HH, and WMD Chimera. Sequencer is an Iron Ether Pithoprakta.

Zlob Folidplier wavefolder - sine edition

video upload by John Schussler

"In my last video I did a comparison with the Zlob Foldiplier [posted here] that involved me using a saw wave as the input audio source.

It was pointed out to me later on ModWiggler that in fact, that's not the best idea. What you really want to do with wavefolders (and distortion) is to use a simple wave like sine or triangle, so the folder can add more magic, particularly on the low end. High-harmonic-content waves like saws are already so busy that you don't get as much of the juice out of the 'folder.

So let's try this again, but this time with a sine wave. Note that I'm not doing the AI Synthesis Wave Animator in this one since it's not technically a wavefolder, and the input wave doesn't matter. I am, however, adding in the Joranalogue Fold6, because like the Foldiplier it's 4hp, and it's currently my favorite.

Let the competition begin....

Two New Waveshapers - August 2023

video upload by John Schussler

"New month, new modules.

I built the Wave Animator from the kit: it's very straightforward with a small part count and easy assembly.

I most certainly did not build the Foldiplier. It's got lots of parts and does not look to me like an easy project. (Zlob's web page rates its difficulty at 3.5/5)

They're both waveshapers, but with very different approaches. The Wave Animator is based on an Ian Fritz design that produces two pulses whenever it sees an input wave. The Foldiplier is a more "standard" wavefolder/harmonics generator, with the caveat that it has a feedback mode best described as 'pissed off.'

Both are quite fun.

Eurorack cv presets - Traffic, Frames, Morphader, VC Transitions

video upload by John Schussler

"With the arrival of Traffic, a new module from Jasmine & Olive Trees, I find myself with several modules that do similar things around 'cv presets.'

The scenario I'm considering today is putting a single module (e.g. Basilimus Iteritas Alter from Noise Engineering) into different 'states' by simultaneously changing multiple cv inputs going to the module. This way you can get multiple 'instruments' out of a single module, in this case a variety of drums and percussion, which can then be sequenced.

There are other modules that do this as well (e.g. Endorphines Total Control), but these are the ones I happen to have. So, grain of salt and all that.

Sequencer is Pittsburgh Modular Micro Sequence. Clock source is Pam's Pro Workout.

Noise Engineering Versio - Praetereo firmware

video upload by John Schussler

"There's a new firmware available for the Noise Engineering Versio modules
called 'Praetereo.' It's a drifting loop maker, in the same vein as the Soma
Cosmos or Hologram Microcosm.

There's a thread for it on ModWiggler with links and detailed info:

No commentary from me in this one, just listening. VCO is a Cwejman VCO-2RM, with one side going to the left channel and one to the right. Seqencer is the OK200 Degree. Envelope: Zadar.

Last in the chain is a Yester Versio module. If you hear a regular delay, it's that, not the Praetereo. And occasionally I bring in the Yester wavefolder. If you hear effects happening but don't see my hand making them, it's the Yester.

Eurorack acid - TB 303 style modules

video upload by John Schussler

"If you listen to techno, you listen to the Roland TB-303. It's the sound of acid, and is such a unique sound that everybody wants and uses it.

Although several makers are selling clones in the original 303 design (with the sequencer and original layout), you may just want to get one in Eurorack without all the fuss of learning the 303 sequencer interface (it's not intuitive).

Here are a bunch of 303 modules that either include all the parts (VCF, VCA, envelope, accent, glide...the works) or just one part (the VCF, which is the most critical bit).

There are others as well, these are just the ones I happen to have...."

New from Bard Synthesizers - LPG and Ring Modulator

video upload by John Schussler

"I recently got a couple new modules from Bard Synthesizers. The VTG low pass gate is available as part of his normal product lineup, but the ring modulator is a custom build. I'm guessing if you like it you could talk him into building you one as well, but note that it takes a bit longer, what with it being a custom build and all.

Here's a little sampler to get an idea how they sound. Plus some extra from the Erica Synths Fusion Ring Modulator at the end for comparison.

Source VCOs are an Acid Rain Chainsaw and a Befaco Pony VCO.
Envelope from Zadar.

MeloDicer save and recall patterns

video upload by John Schussler

"One of the killer features of the Vermona MeloDicer is the ability to save and recall patterns. Press the C button, select a slot with the encoder, and press the encoder. Saved. Press the D button, select a slot with the encoder, press the encoder...loaded! Easy and quick."

Melodicer vs. Black Sequencer - one or both?

video upload by John Schussler

"I haven't spent much time with the Erica Synths Black Sequencer, and I noticed in a thread the other day somebody mentioning it serving as a substitute for the Vermona Melodicer.

Say what? I have a Melodicer, and it's the cat's meow. Can it really be supplanted by the Erica Synths offering?

They're big modules, so it's worth asking the question. Which is what you have asking the question of whether I keep both or just one.

Source VCO is an Acid Rain Chainsaw. No envelope, just the output gates from the sequencer’s going to a Bard tube LPG.

Eurorack Formant Filter Comparison

video upload by John Schussler

"I now find myself with 3 separate filters that do "formant" filtering, so clearly it's time for a comparison. I'm literally getting my ya-yas out. And my yi-yis, and sometimes my wa-was. Just depends on where you turn the knob....

There are other formant filters out there, this isn't all of them, but it's all the ones I have, so don't assume this is the exhaustive comparison.

Formants are fun. And though I don't get into it much in this video, using formant filters for "regular" duties with only mild formant effects can be quite interesting.

Actually, using formants sparingly should probably be the rule. There's definitely too much of a good thing possible here....

Vice Virga - Great fill maker for drums

video upload by John Schussler

"In an earlier Beat Mangler video I tried out the Jam Jam from Noise Engineering, and had a hard time getting what I wanted out of it. Turns out what I really needed was a Vice Verga. That's arrived, and is clearly the answer to the question: 'What if you want some interesting drum fills on a regular basis, but don't want to do it manually?'

I used a 2hp Burst in this patch, but I'm guessing if I read more of the Pam's manual there's probably a way to do it entirely within Pam's.

Either way, Vice Verga is a great fill maker for drums."

Jroo Loop - Pitch shifting tape looper

video uploads by jroo

video upload by John Schussler

"Here's a fairly simple tape loop module from Jroo called Loop. When you
change the speed of the loop it actually pitch shifts, which makes for some
really interesting opportunities for new harmonies.

This whole video is the same very simple sequence from a Pittsburgh Micro
Sequence b driving an Acid Rain Chainsaw VCO. On top is a bucketload
of reverb from Valhalla to let things ring out into space.


00:00 Intro
00:20 Clean
11:53 Distorted"

loop is a frippertronics-style dual mono digital tape loop, echo and delay utility with adjustable tape speed, play head position, feedback and levels. It has a customizable loop length of up to 2.5 minutes.

loop is modelled after tape loop systems where audio is recorded to and played back from a tape that’s continually looping. Several interesting effects can be accomplished in this system when the position of the play head, tape speed, direction, and audio and feedback levels are modified. loop gives you manual and CV control over each.
