I don't share everything I'm uploading to YouTube here anymore but I think there's a lot for people to get from this one - https://youtu.be/PYj-WK7cGjs



TIMING INDEX BELOW - SKIP AROUND! smile GRAB HEADPHONES YOU'LL APPRECIATE WHAT THIS DOING EASIER ... pinky promise. Mr. Green

Here's the very excellent, very underrated, very overlooked LRMSMSLR module from WORNG Electronics ... that's wrong, spelt wrong ...

The LRMSMSLR takes a stereo input (left and right) then sums them together to create a mid input and creates a signal that's a difference of the two to create a side signal. This is a common mastering technique often doing things such as removing low end from the side stereo elements to clean up a mix. The mid signal is a single mono channel and the side input is a single mono channel, it's the way their phases are flipped and interacting when brought back together to recreate a stereo image. It's great for taking that side output and using mono FX modules that when brought back into the module create stereo images with those FX on them from super wide to more subtle stereo images (with a dry unprocessed mid to keep things focused). It can also do some unity summing, CV difference / averaging. Lots of patches, lots to get through, skip through the index below if you can't watch all the way through.

TIMING INDEX

00:00 Hello and patch previews of what’s to come.

01:03 Verbal feature walk through, what is mid/side? Patch suggestions and WORNG’s patch examples from the manual.

DUAL DETUNED OSCILLATOR PATCHES (mono FX modules turned stereo)

3:33 Two separate oscillators with detune waves into the left and right. Using manual control on a VCA to show mid and side signals and how that affects stereo image.

05:33 Processing the side channel through a phaser (XAOC Kamieniec)

06:40 Processing the side channel through a pitch shifting delay (Make Noise / Soundhack - Echophon)

07:29 Distortion over the mid channel (Metasonix R51)

08:14 Distorted mids and phaser modulation sides

08:36 Side signal through a reverb (AJH Synth Finaliser R-EQ) with the addition of some pitch sequencing.

09:36 Stereo sideband creator - Stereo Ring Modulation FX (AJH Synth Ring SM)

12:43 Using a VCA to modulate stereo width.

SEVERAL EXAMPLES OF STEREO AUDIO PROCESSING

13:39 Modern cutting/bright synth riff. Showing the mid/side elements and processing the side with FX that “as if by magic” now appear in stereo.

15:59 Ambient piano. Stereo piano, resonator, reverb stereo signal. Splitting into mid/side and processing through a phaser.

17:02 Acoustic drum loop. Using the side signal as a way to pull out and/or remove the room reverb around the drum kit. Then processed through an Echophon, frozen and mangled.

18:04 Dirty, gritty bass wub-wubs. Side signal reverb added.

UTILTIES

18:58 Mixing the left and right signals from two mono sources (to left and to right) and taking the mid output as a summed output.

19:53 Using the mid and side inputs with two different CV signals as a “cv averager”.

21:07 Using two mono signals into the left and right and using the mid as a summed CV and the side as a CV difference both modulating independent VCAs for relating but different modulation signals.

USING TWO DIFFERENT FILTERS (even stereo image without matched filters)

22:47 The last patch uses two different filters over the mid and side and two different modulation signals of them. This creates a stereo filtering effect even though I don’t have two of the same filters to get a matched / even stereo image. This also means filtering them differently creates a moving stereo image/width. Very cool.

Thanks for the video, Ben! The LRMSMSLR is the $100 secret to COSMIC THIXXNESS (doctors don't want you to know!). And I'm glad you emphasized both the audio and CV utilities.

This module really shines when placed next to a CV-able crossfader (e.g. Cold Mac) to add motion to the audio sources.

It's worth mentioning that mid-side processing has drawbacks if your effects chain introduces phase incoherence between the channels. Specifically: your stereo track can have a lot of phase cancelation if mixed down to mono.

seriously thanks for highlighting this, Ben. I just finished watching and it's absolutely apparent that this module is some kind of wyld wizardry.

Lots of power in 4 hp. Thanks for the heads up and vid! Wondering if i can send it through outside fx and back into it again.

Much appreciated. I've had this and Vector Space for about a month and am digging digging digging - both are fantastic, deep modules.

Just ordered on the basis of this video, was on my list but was pushed to the top.

This plus Nearness plus Cold Mac plus stereo delay (not necessarily altogether) feel like a strong set of spatial tools.

Not really, that is just a coincidence due to the M/S decoder stage having a fixed gain of -6dB or ÷2 (to prevent clipping). (M+S)/2 is the average of two signals, M and S, but if you remove one, say S, the output will be M/2 whereas the true average should be M.
BillyB909
So what would be the practical impact of that to users of the module?

Encoding and decoding M/S both uses a sum and a difference, but if you use two unity gain stages you end up with 6dB overall gain so a -6dB gain needs to be introduced to compensate for this.

This one looks like it is done in the decoder, but is is more useful to do it in the encoder to prevent the Mid clipping and as Eurorack does not have 6dB headroom two +/-5V inputs will clip. To prevent this you could always use the sections the other way around, if you can get your head around the labelling--MSLRLRMS.

It actually is -6dB on the LR->MS stage and then unity on MS->LR, for precisely that reason. thumbs up There's an error in a graphic in the manual which makes it look like it's the other way around which I imagine is why the video is incorrect, I hadn't picked up on the mistake until now and will fix it and get a new version up straight away. edit: the new version of the manual is now online.

Regarding your comment about using it as a CV averager, there’s still two inputs even if you unplug one lead, it’s just that your second input is now 0V. The average of L and R when R = 0V is L/2.
BillyB909
Thanks for replying, and making the correction. Good to know.

It's still a coincidence and only a weighted adder. There is a difference between an input being at 0V and not being plugged in. A true averaging circuit (two resistors and a buffer at the node) will have the correct output in both cases.

I'm not sure what the benefit of this "feature" is anyway.
Stab Frenzy
Well I’m sorry that me writing up a few different bonus ways to use a mid side processor with CVs in the manual of my module has gotten you so cranky. seriously, i just don't get it I’m just trying to encourage people to patch in interesting and creative ways, my apologies if that doesn’t fit your world view.
desolationjones
Stab Frenzy don't let the pedants get you down. I think that showing seemingly esoteric uses of the basic functional blocks is very helpful for true "modular" understanding.

Ben's video does a great job showing how to use the adders for complex modulation around the 20min mark. It could also be used for transposing a pitch CV, or attenuating and/or inverting a CV.
BillyB909
For other and future readers of this thread, I own the module and it does a great job. I would recommend.

I’m not going to jump in and and comment on other people’s need to find fault with it (who presumably don’t own the module and or have used it in practical circumstances). Readers can draw their own conclusions.
