Lovely!! Any chance of a video walkthrough once you’ve feeling at home with it? And is it bad form to ask what that cost?

I’ll definitely do a short video once everything is set up and I’ve learned some tricks :slight_smile:

In terms of cost, I’ll just say that it’s more than an off the shelf standard mixer, but not so much more that it’s out of reach :yum:

Are those banana inputs I see?

Yes, banana inputs for audio and also banana cv inputs for the per channel VCAs.

oh boy that’s awesome! curious for sure…

Hi!
After the interest shown for some of my mixery creations, I though I’d make a separate post to show some of my latest creations and to talk more generally about matrix mixing, usage ideas, interface design, and signal freedom philosophy.

Let’s start with that last one, then!
Here some pictures!
The idea behind this unit is to have both a “regular” mixer and a matrix, so you can use it as your main and only mixer for performing and recording.
The left part is the “regular” side, inputs with various types of buffered connectors, a Pluck’n’Duck VCA for each channel (works with audio and CV as control, and can act as a regular VCA or a side-chained compressor).
Then a global gain control (+/-14dB), 4 AUX sends, PFL, mute and a 7.5mm master fader.
In the right section things become more interesting, this is the AUX matrix, here you can basically route any signal to any effect in any order and amount, all without disconnecting anything. Of course you can also generate feedback (the “feedback path” is marked by the white knobs here) And if you keep all the knobs in the aux matrix down, you can still use the aux send-return as if it were a normal mixer.

I’d be happy to answer any question and talk about ideas, and maybe also post more matrix mixers here!

Set your signal free :fist:

I’ve long wanted a good stereo matrix mixer in a small form factor. It might be the next thing I have custom made, since that seems to be the only way. (Other than Eurorack, which I don’t do.) I am kind of amazed that with every possible device available for sale, something so simple is missing in action.

Alessio is a great guy to deal with and his work is outstanding i got a 8*8 matrix eurorack compatible from him, really happy with it!

Passive, pretty compact* 5x5 matrix mixer that I made…

Not for those with fat fingers!! No case because, well, I’m not very good at them :slight_smile:

*(Less than 100mm on each side)

here is a small 3x3 I made as part of a series of little minijack tools.

@jonsimon have you ever tried passing control voltages through that Mackie? I’m curious if it would work.

lovely! i kind of want to build something similar but active, for eurorack but probably not acutally in the rack. but also my current ideology dictates just soldering 1/8" jacks onto the smashed up passive 1/4" matrix I already have and actually recording some Noise.

haven’t seen it mentioned here yet, and since you brought up euro – more of a routing controller than a mixer i guess since you’d have to have attenuators on levels elsewhere, but it seems fun :slight_smile:

yay! thanks a lot!
Super glad to hear you’re happy with my mixer, it’s always a delight to see my children in the wild!

Wow, I’d love to buy one of these. Looks so handy!

Well, I still have some PCBs around - I can sell you a PCB, put together a kit or could make one for you? :slight_smile:

@namke Interesting, I’m in the market for a matrix mixer, mainly to be able to mix in FX in my Eurorack, for example for different drum voices, before sending to my main mixer. Would your PCB fit behind a Eurorack panel? And where would the limitations of passive come in, vs. an active mixer?

Passive matrix mixers have all sorts of quirks :slight_smile:

  • Because there is no buffering, inputs and outputs can affect each other in sometimes unpredictable ways;
  • Signals are quieter (as might be expected because there’s only attenuation on offer here)
  • but no power is required…

My PCB is just about 100mm square, so whether it fits in Eurorack would depend on the gap between the rails (I have a sneaking suspicion that it won’t fit, however it might be possible to wiggle it in).

I’d be interested to see a panel design for it - I tried to make all the holes regularly spaced!

OK. It should fit - max recommended PCB height is 106.5mm, and panel height is 128.5mm
The quirks sound interesting! I guess I’m really looking for the predictability of an active mixer in this case though.

I <3 matrix mixers. I use two of them in my system - the Midas one as an effects routing brain for submixes and the Hinton one as an all purpose bussing system and interface between modular and studio gear. Once you get into the matrix frame of mind, traditional mixers with only a couple of aux sends feel very limiting. Matrix mixing just feels more synchronous with the modular mentality of infinite possibilities.

Ahhhhhh. I’ve long thought about integrating an XL88 into my setup… I occasionally search for used ones at a manageable price but no such luck.
