would love to hear some Audio from you.
I'd be happy to make a sort of demo of it, but just beware that I probably appreciate sounds from it that hard-core fm enthusiasts wouldn't necessarily appreciate. I don't really know much about fm synthesis beyond the basics. :razz:
i am not a hardcore fm enthusiast, i am a Sound enthusiast, i wrote to you because i liked every single Audio snippet you posted on Muffs.
Oh, thanks! That's mighty kind of you. I'll record something tomorrow. :)

Hi folks,

Sorry I have not been able to find the time to address this issue yet. I have been more focused on some bugs that were brought to my attention. However, I have now found the time to address those and intend to work on addressing the leaky VCAs problem in a firmware update soon. Stay tuned.

Could you perhaps give me a sense of the voltage level that your modulation sources are closing at? I think I basically need to pick a small positive voltage threshold below which to explicitly set the gain to true 0 in the firmware.

Thanks for your patience,
Will

We hear you on this, but we had to limit the functionality to the modulation matrix due to the limited CPU capacity of the device. Blending between full sets of parameters would have required double or more CPU capacity than we have whereas blending just the modulation parameters is considerably less CPU intensive. Perhaps we can account for this in future products.

Perfect Circuit just said Quad Operator is one of the best oscillators of 2019!

https://www.perfectcircuit.com/signal/b ... ators-2019

“Humble Audio's Quad Operator is a four-operator FM engine in a single Eurorack module. FM is a truly incredible synthesis paradigm—it uses networks of oscillators frequency modulating one another to create tremendously complex timbres ranging from brass and electric pianos to continuously evolving textures. And while the tonal palette of FM is quite broad, it has a bit of a poor reputation—largely because the original FM synths (Yamaha's DX series) provided a particularly minimal interface for controlling a huge number of parameters...and as such, were very difficult to use to their full potential.

Quad Operator aims to address this difficulty by providing a dedicated hands-on control for all of its parameters. It does this by effectively dispensing of the traditional FM concept of an algorithm (a fixed FM path between multiple oscillators) and replacing it with an FM routing matrix, allowing easy creation arbitrary algorithms. And by providing CV inputs for the gain of each of the four operators, dynamic changes to the sound can be source from any modulation source in your system.

Quad Operator also provides CV inputs for each operator's ratio and waveshape, as well as individual outputs for each operator. This has the makings for a remakably complex FM voice or group of voices, especially when paired with clever modulation and use of the Algo algorithm expander. Quad Operator provides maybe the best interface for FM synthesis we've ever seen in any format—Eurorack, keyboard, or otherwise.

Oh, I understand, didn't really mean it as critique. :) I have to say I agree with Perfect Circuit - it's an excellent implementation, so hands on and easy and fun to use.

I still haven't gotten around to recording a demo of it, but I will. :mrgreen:

Andrew Huang's demo was awesome in all aspects. Swell patching, good run down of a very cool module, and also a nice video production. :party:

i have immediately fallen in love with this awesome beast of a synth! its probably my favorite module for what it does. i still love my preenfm2 but this bad boy is beyond that in many gorgeous ways. modulation of so many things is a start. this module will be relevant forever. its fm plus whatever you pair it with, which means a literal plethora of outcomes. fm is probably my favorite method of sound generation, and this thing lets you inside fm with your favorite modulation at any point along the way.

cheers!

Would it be possible to eventually have an expander the just saves patches of all knob settings without the cross fading function? With all these controls I could see the utility of patch saving of all settings could be very useful.

Yeah a LCD with 99 presets and maybe still have crossfade would be great. If it could take a clock input and work like a sequencer that would also be good for a performance.

heres another twiddle dee dumb. i can totally appreciate the strengths of this module! you should hear the rumble comin from this thing. wow. im in love. that squelchy clangerous place where i wanna be! maaaan, fm was never so fun. im resisting buying another one! id sure take one with 8 operators too if youre thinking of that lol

theres a little fm aid in there too btw.

ok an idea: make the algo interpolate between all 4 captures, not just 2!

Very seriously considering this module. When is the internal VCA/gain issue expected to be fixed? For current owners, how disruptive is this issue?

Is it possible to send individual v/oct to each operator to use as an independent 4 voice module? Edit: I just RFM and realized it can work this way!

if that's doable, a randomize would be great! The randomize on synth editors for subtractive synths was mostly "miss" but for FM synths it often provided a great starting point, at least.
thanks!

Had a chance to spend some quality time with the Quad Operator last night. Bit of a learning curve, but nothing a quick trip over to YouTube couldn't clear up. Really loving the subtlety that this thing offers! While of course it can still get into insanely wild territory if you're so inclined! :yay:
