Wow! :eek:

This might be the FM voice I've been waiting for! Those Humphrey demos are dOpE!

Please, please, please consider offering a black panel option.

Hi Batik Rhys,

We redesigned the website some recently and forgot to keep this bit. I've added it back--scroll to the bottom of the page and you can leave us your email address for future contact over at www.humble.audio

This is DSP-based, fully from scratch implementation (which I will open source anyone interested in modifications. Without a DSP-based approach, some of the features of this module would not have been possible.

If you're interested in an FM module that uses the Yamaha chips, I suggest looking at Akemie's Castle which has been around for a few years.

I love the open ended architecture, TBH I can’t think of a better design.

DSP based isn't an issue - only wondering since Akemie's Castle is a larger module. :)

How about a more exotic sample rate (like 64KHz) as a compromise ?

Little point going above 48k in most cases.

In the final rendered audio, yes, but you want the highest resolution and sample rate for internal signal processing.

The TX81z for example has a samplerate only a tiny bit higher than that, around 55khz. It won't be an issue.

Will this be offered as a diy project? And yes the expander on the mod and index would be a killer thing.

I think I will not be offering as a kit unfortunately. The surface mounted parts are very small and challenging to solder. I have not decided just yet as I need to understand how my business will do first, but I may publish hardware specifications for those who want to fab their own PCBs and do the soldering (after I have recovered by development costs and paid some other bills).

The electronics are assembled for the first production batch! We are now waiting on aluminum panels and final custom large scale knobs (for coarse and fine, and crossfade on the algo. not for the thin trim pots we mostly use).

This is still a few more weeks at least. I will post here when I have confidence the precise timing when I can take orders from shops (US possibly CAN) and distributors (EUR and other international), but I expect it to be 2018 for sure. Some additional time will be required for units to flow through distribution channels--I will not be selling units direct to end user initially (I am a one man operator and it is too much work for me right now).

This I cannot do. I use a microcontroller system on a chip from Standard Micro which has some limitations (but is also really fucking awesome). In my implementation of the hardware, it is important to use something called the Serial Audio Interface (SAI) which enables me to speak with peripheral ICs with very precise and consistent timing and keep all the audio functions both internal and external in as perfect a timing as possible. The SAI only runs at typical audio rates, 48k, 96k, 192k. I can't take another step up as I don't have the CPU headroom.

Further, I think your concern is arguably unfounded :) Aliasing is actually a beautiful part of the FM sound, always has been. And it's, in fact, quite necessary for percussive results. Aliasing issues are much more of a concern in the recording and re-production world, and aren't such a pain point for single source and relatively simple sound sources (not exactly simple, but in the big picture...) like the quad operator (I don't have built in reverb or other "high information" effects for instance, which is often why in-the-box synths often really need high sampling rates). I also put in a lot of effort to band-limit the waveforms, which gets you most of what you want here. And I can also firmware update if there's a need. I think you won't be disappointed!

These made the rounds from Superbooth last spring, but I thought I'd post them here for your appreciation of you haven't had a chance to see them already!

In no particular order--all are solid interviews and sound demos! Pick your favorite! Although, my "um" rate was out of control with Synthtopia! It was first thing on the final morning of Superbooth, and I didn't really sleep the night before :D. Saturday nights in Berlin, what can I say... Otherwise, a great video!

they aren't yet that i'm aware of. divkid just posted a video showing this off... looks like i need to find 30hp in my case somewhere. :deadbanana:

seriously, this looks super dope and extremely playable, with is my biggest gripe with dedicated fm synths. the dx synths are basically giant preset machines to me, lol.

i would agree that cv over each pot in the matrix would be killer, but that would add a bunch to the size. this looks perfect otherwise. the expander looks badass too. basically allows you to save three presets (i think?), and then morph between the three presets as well as the live panel. neato!

Hi folks,

Apologies for being a bit MIA and setting expectations poorly on the release timing. Doing this for the first time has proved more challenging than believed. In the great words of the terrible Donald Rumsfeld, you've got your known unknowns which bite you sometimes, and then you've got your unknown unknowns....

We pursued a project to make some custom knobs, which took a surprising number of iterations to get right. This kind of laughable matters less for the quad operator than it will for our next module (details forthcoming), but we wanted to establish a consistent design language before proceeding with the quad operator. The good news is--all our electronics and panels are assembled, software is loaded, and we're receiving the knobs very soon. We can now say confidently that Quad Operators will begin shipping wholesale in May!

Yes, as some have mentioned, DivKid has teased the module recently. He's got the first unit with full production detail including a late round like-production set of knobs for coarse and fine tuning as well as crossfade on the Algo.

More content is to come very soon as will pricing details, availability, etc, etc!

Hey folks,

A couple of things:

Preorders are starting to go live with various online shops in the US, and we expect more to be going live soon in Europe and other parts of the world!

My friend Josh Humphrey joined me at Superbooth this year and gave a nice demo performance made with sounds exclusively from the Quad Operator (including a bank of percussion samples designed and loaded into a Model:Samples beforehand). Check it out:
