- After having the pleasure of testing the Quad Operator from Humble Audio for a while now it's great to put up a first video just exploring some basic modulation and FM synthesis. I have 3 unsynced looping envelopes controlling the level of 3 of the operators and play around with tuning ratios, depth/index of FM, waveshapes and feedback. More video to come and more explanation and the following patches unfold and we head towards the full demo around the release of the module.

Let’s chat about FM synthesis indeed ❤️
Thanks so much Ben! Quad Operators and the Algo expander will be shipping to shops very soon. If you're interested in buying, please contact your favorite shops and ask them to stock us!
Is it all digital?
@@NickHchaos Yes it's a digital implementation under the hood. I think the implementation offers a pretty convincing analog character to the triangle, square and saw shapes. The modulation can be fully turned off and the individual operators can be used for subtractive patches this way. I think something about doing it in this format (perhaps circuitry noise in the analog stages and other factors) also warms up what's a traditionally kind of more sterile sounding synthesis technique.
@@humbleaudio8860 I'm a pretty die hard analog guy when it comes to sound generation, and yes, it does sound good, well done!
@@NickHchaos Thanks :) We're pretty strong believers that this can be a real workhorse of an oscillator module even if you're not all about FM. More fun to come here as well :D
humble audio interesting. I thought it sounded a bit more ‘raw’ than my Digitone.
Actually quite an impressively versatile sound source putting knobs on a fm synth was all ways the way to go
Terrific how you have control over the algorithm, not unlike FM8.
Yes. This was largely inspired by my love of FM8.
The operator feedback on this thing is wonderfully brutal! But wow, this is exactly the sort of thing that I might buy
If I get into modular.
Sick little unit
Excellent patches Ben, I'm completely floored and could listen to this for hours, which.... I hope to do soon.
Very nice, it has a lot of tonal similarity to Eliments by Mutable Instruments but the FM capabilities on this one are quite spectacular.
sounds like the Yamaha TX 216 this is a must buy module
I'm liking that! Would work well with a bunch of the modules from 2hp. I can feel another modular build coming on 😱
Super nice, love it
Like this. Like this a lot.
what a beast.
This sounds amazing!
Sick unit. Thank you for your video !! As always good.
I love this...but I just can't with those cone knobs. Are they swapable?
I I want the octal operator. Two of these would do, however. Send contributions to the bitegoatie FM fund.
Meantime, we await the kid’s next vid.
Love it.
Thanks for the video!
Awesome! It would be interesting to cross modulate this with the Akemies castle. I see that it has an expansion module called Algo then to access control over algorithms.
Wicked! Guess that's the expander next to it?
Correct. More information to come, but it will essentially allow you to save modulation send knob positions as Algorithm presets and allows you to crossfade between pairs of them with the knob or CV. You can also crossfade between the live knob positions and an algorithm.
OMFG I’d sacrifice a baby to Cthulhu to get one of these!!!!!
I've been considering something along those lines using the 4ms vca matrix with a doepfer a-111-4 and that poly 3 way crossfader. It'd be a complete spaghetti junction, more versatile but less practical i guess.
@drbobdobalina
Doepfer A-138e
It's an odd one, but looks super useful to me
How does this compare to the Akemie's Castle in terms of features? Not a fan of those tiny knobs, but looks very intuitive and sounds great.
AC has a limited set of fixed algorithms to work with, but sounds nice. Downsides are the audible stepping when modulating the levels.
I found that akemies Castle was difficult to tune, and went out of tune. Like the correct pitch was in between two quantised points, and I had to get it to waver between those two points, which was very difficult/fiddly/random. I had a similar experience with the MCO... I miss the sounds of akemies though, its really beautiful. Quad op looks amazing.
Please do a comparison vs Akemie's Castle!
no chords here i guess :(
I would 100% go with this over Akemie's castle. I am going to sell mine soon and buy this instead. Akemie's is great for static tones, but because of the chips in akemie's castle, you can't envelope the levels without a very very noticable stepping in the signal. Akemie's sounds amazing and has more waveforms, but is too limited by it's chips for me to truly appreciate it. What's really going to be interesting is when I ger around to adding two more rubicons and having a through zero FM analog synth.

It looks and sound great. The only thing which I really think it's missing is a 1V/oct input for each of the oscillators so that you can play the module polyphone. You could still get useful FM tones out of it, if you modulate each oscillator with itself. I don't quiet get why euro rack is not moving more in the direction of polyphonic modules, except a few modules like the Doepfer A-111-4.
distorson the module is polyphonic. When set to free, each ratio in becomes a v/oct input
It’s all on the humble audio website
@@eph_kni thanks for pointing that out. I wasn't aware of that. This make things even better.
distorson dude I got you! I had the same concerns. I figure if you’re going to make a $500+ investment, you gotta know
Great info Burns thanks
How many hp?
Trying to figure out what I should sacrifice to make room for this beautiful thing
They mentioned 30hp in last year's superbooth video
Main unit is 30hp. Algo expander is 4hp
ingenious! would you recommend it for both linear and exponential fm ?
This just does linear FM, which is the more musical of the two. In essence, it's modeled off the same fundamental techniques as the Yamaha DX series. You're of course welcome to plug audio rate signals into the 1V / oct for a exponential FM type effect if you like :)
drbobdobalina Yes all the old tricks can be played in addition to the Quad Operator’s internal linear FM
Is the full review taken down? I can’t seem to find it but I swear I watched it..(?)
✨👁️👁️✨ perfect... 👌🏻
When more that one source is modulating a signal, how are they combined before being applied?
This as a stand alone with larger pots would be even more incredible. Reaching into my rats nest of a rack to turn all these little pots w these sausage fingers ain’t happening
we mocked up a version of the front panel with full size pots and all the CV off to the side and decided that it was just too wide to sell feasibly. That being said, there may be a standalone FM unit in our future :)
@@humbleaudio8860 Standalone FM UNIT?!?!?! YESSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSS
Is it possible to put larger knobs over these sorts of pots? It looks like there's enough space between them that if you could, they might fit depending on the kind you use.
Do the little knobs have a centre detent?
4:10
Are there any matrix mixer modules that could do something like this with 3-4 external VCOs that have FM inputs?
maybe the 4ms matrix mixer? not so sure never tried that one so far.
this vs akemies castle? any thoughts welcome
Scroll up some entries & you'll see a couple of opinions. It looks like this is preferable to AC
I was super excited about this. Then found out this will cost $500+ At least I can dream.
