BRO what you have here is a custom pedal development test-bed. General workflow: 1) jam out on the modular and find a sound you like 2) trace back the signal path and do a little boolean algebra to simplify out any redundancies 3) draw a circuit diagram that describes the simplified signal path and hardwire all key modulation settings with whatever appropriate surface-mount components will replace the dial. 4) get your circuit fabbed up on a PCB that fits inside a pedal. there's a whole neighborhood of challenges to overcome in acomplishing each step, for sure, but it is *possible*

There is also modular software synths as well which goes through the same thing. I figured they learnt it through just playing around with their daw when they first started digital music production. And how they immediately knew that the pitch cancels each other was also due to their mixing experience with phase cancellations on tracks they had to deal with.

[@BLIZZARDX3]

This entire episode was incredible as a music producer it was great to see a traditional guitar transformed into so many different sounds by using synth modulators ultimately this will be the future of guitar performances

[@analog-j]

The guitar to control volume experiment as other have said is just AM, I wanted to drop the relatively simple math though for those interested. A typical VCA is a 2 quadrant multiplier (won't go negative, as Andrew briefly mentioned, which would be ring modulation), and from the video you can see that's what they're using, an Intellijel Quad VCA module. If the oscillator they use was at 500Hz say and they played a pure 200 Hz tone to control the volume, that would create to "sideband" signals at 300Hz and 700Hz (500 +/- 200) so you'd hear all 3 tones - it would look exactly like my current KZbin account icon on a spectrum analyzer. ;) In this case the guitar note has multiple harmonics all generating the same math at once, so what you're hearing is the original oscillator frequency +/- additions at all frequencies in the guitar note spectrum. That's why playing a harmonically related note to the oscillator sounded good, the new added sidebands become good sounding integer multiples of the original oscillator. Anyone that wants to try this out could set it up in VCV Rack for free to play around. Very cool video!

[@mr-meek]

[@LiamFarleyMA]

The effects they keep making are analog effects that are limited by the fact they're analog. Red Panda, Hologram Electronics, and Empress have really cool innovative digital pedals. Just look at the zoia, basically a modular board in a pedal format. You could also checkout the Norns or the Organelle which aren't strictly guitar pedals but certainly can function as them and can be setup to play sounds that imitate a modular system. I mean due to the open source modules you can literally use some exact copies on the organelle.

@andrewhuang 7:25 I don't think you guys realized it but you just invented AM and FM radio. @robscallon was talking about amplitude modulation when he wanted to control the volume of the oscillator with his guiator and you were talking about frequency modulation when you said control the pitch of the oscillator with the guitar. You were half way to making a radio already since it's an electrical signal. Just send the signal to an antenna instead of a speaker and turn up the oscillator pitch to a 10 Khz (or 10MHz for FM) and you got yourself a literal radio station.

[@ULTRAVISTA.]

Listening to this in really good headphones was such an experience for me. I love the guitar. These sounds are insane.

[@Someone89a]

For anyone a bit confused about the amplitude modulation section - the guitar’s vibration frequency (aka pitch) is essentially acting as a secondary oscillator, AM-ing the sine wave. That’s why all the phase relationships and overtones matter - it’s not just a 1:1 volume to cv relationship, it’s utilising the raw oscillations of the guitar as an AM source.

I don't think it's the electric guitar sound more than it is people's ability to be stuck with one type of sound. How do you define "the electric guitar sound", you can't because it's different across the board. Effects pedals do this, just to a lesser degree. I mean even The Beatles were experimenting with how to modify sounds like this in the 60's. It's just that some people have this idea that Guitar=Rock Music but then say that doesn't sound like Rock Music. Just stop putting things in borders and you'll be more creative yknow.

12:40 Multiplying two tones of frequencies f1 and f2 will produce a signal made of two tones: f1+f2 and f1-f2. So modulating the amplitude of a 200Hz signal with a 300Hz will give you a 500Hz signal and a 100Hz signal. Here's the what the 12 tones above C4 give you when combined with C4 (to the nearest half accidental): ♯ ♭ 𝄳 𝄲 C4 → C4 & Nothing/DC-offset C♯4 → C𝄲4 & B(-1) D4 → C♯4 & B𝄲0 D♯4 → D𝄳4 & G1 E4 → D4 & C𝄲2 F4 → D𝄲4 & F2 F♯4 → D♯4 & A2 G4 → E4 & C3 (wow a 5th makes it sound like an octave major 3rd interval) G♯4 → E𝄲4 & D♯3 A4 → F4 & F𝄲3 A♯4 → F𝄲4 & G𝄲3 B4 → G𝄳4 & A♯3 C5 → G4 & C4 (octave makes a perfect 5th)

[@Dylan-Juhan]

Am I not high enough to get this?

[@matthew.wilson]

1) This is actually a thing in the pedal world (albeit still a novelty). Check out the Empress Zoia and the Poly Beebo. 2) The "B Filter" is the reinvention of the vocoder, more or less :) Edit: (2) is not correct (thanks eyeball226). Look up vocoders - the history alone is fascinating. They're both cases of some function that combines 2 signals in some kind of filtering/multiplicative way, but that's about as far as the similarity goes.

[@sbsftw4232]

They should have tried the same effects with a mic input

[@vitaliistep]

Source Audio C4 is also something like Eurorack in a guitar pedal.

[@matthew.wilson]

Ah neat! I hadn't seen that one yet.

[@eyeball226]

2) Not even close I'm afraid. The "B-filter" was just plain half-wave amplitude modulation. Vocoders are way more complex and work in a completely different way.

[@matthew.wilson]

Ah, I need to do some reading then. I had understood that a vocoder was essentially just a multiplication or convolution of 2 inputs. My bad.

[@johnsmithy3790]

Very cool. This is what I imagine the conversations look like in most studios, just playing and trying stuff and hopefully learning something new fairly often.

[@j_as_in_j]

Andrew, I love how you know so very much about audio! It really is very impressive.

[@Marklar3]

8:19 Sounds like he's describing amplitude modulation (AM synthesis). I think that's what's used to make metallic percussion sounds like bells and gongs. I predict that when he changes pitch on guitar it will be difficult to hear a change of pitch in the final sound, but the formant will be slightly changed, giving it some perception that it's higher pitched even when the fundamental is the same.

[@roseopheliashepherd8379]

You two are such a great power-duo, you both answer "all" to "what genre do you play", and I love seeing Rob's unbridled flow of concepts getting funnelled through Andrew's own respective discipline, knowledge and talent. It reminds me of the creative duo-ship of my fiance and I x

[@davidwave4]

Andrew and Rob is an unrivaled pairing

[@TheGuywithaChannel]

WHY DID I ONLY GET RECOMMENDED THIS TODAY, KZbin?!?!?!?! I DO THIS!!! :D I use a ton of wacky modulation effects to make inharmonic timbres, microtones, "guitorgan"-style synths, etc. I've never even owned real pedals or a pedalboard; I didn't understand why I would do that if Eurorack had so many more wacky options available.

[@nilspaar1999]

That creation of yours is truly the future of music. This is true artistry at its best.

[@BldgsFallStraightDwn]

You kinda touched on some sounds that Robin Guthrie from "Cocteau Twins" was able to record using physical tape delays and MANY pedals and electronics that combined to get pretty "dreamy" stuff back in the 80s and 90s.

[@frikisaurio]

13:33 alive grips

[@frikisaurio]

death grips At home

[@snookerwither9955]

That sound at 17:00 was amazing! Could have made a great song

[@JCKnuckles]

Watching the both of you riffing off each other was SO gorgeous and also really inspirational. Diggin' it bigtime.

[@jameshamaker9321]

This is good stuff, beautiful i watch a video with Rob playing an accustic, only then to follow up with, a video of him and Andrew playing around with his giant synth module.

[@SlyHikari03]

Reminds me of the band HEALTH and what Trent Reznor does with Reaktor/what John Frusciante does with his Doepfer stuff. Also, the more ambient stuff before the osc test reminded me of Post Rock and minus the bear. 17:00 reminds me of Meshuggah.

[@Rogue_Steve]

I immediately thought of HEALTH when they started messing with the granular synth.

[@SlyHikari03]

@@Rogue_Steve totally, Especially the octave up and octave down thing, reminds me of the crazy glitchy thing on most of their guitar tracks.

[@BenjiMeisterDK]

i feel like everyone became smarter with this session

[@CC-ks3tj]

The part at 15:28 totally sounds like the breakdown part of a song called "The Great Destroyer" by Nine Inch Nails (around 1:46 into the song). Really, really neat stuff here.

[@EastOfGreenwich]

Hi Andrew. Learned a lot from you over the last few years. GRATEFUL.

[@novdt]

really nice guys. all i had was a group of breadboards and a bunch of 4000 series cmos chips, ttls 555s, and 741s. when running two 4011osc against each other one could generate ring modulations in headphones combined with sterophonic flanging, when moving things on my workbench circa 1978

[@galenwilliams2401]

6:25 This tone feels super reminiscent of Antidote by Travis Scott, really cool timbre!

[@watercrystal8976]

travis fire

[@calebfuller4713]

8:15 I had to think about it for a bit to get my head around what you are proposing with the CV control on a fixed note. What I suspect will happen is that it creates a harmonic chord effect, for example generating a 440Hz frequency then playing an E note into the CV will basically generate an A5 chord. Now to find what actually happens...

[@makssquivias2118]

Rob achieves SHOEGAZE yeahhhhh

[@lefxxwill7740]

this is so sweet to watch! Exploring and having fun

[@Treyfc]

I’m late but an entire first of October could come from this

[@sorak185]

Those panning effects were tripping me out... just with decent stereo monitors! That whole thing is insane.
