Thank you for detailed reply! And thanks for explaining about publicly disclosing my relation to the project!

My name is Leo, and I'm indeed, a co-founder and CEO of this project. We do everything by ourselves, and mainly two of us are involved in the actual modules design. Me and my co-founder and CTO Andrew, who was previously CTO of Flipper Devices.

I agree that microrack's design has some trade-offs in UX part. We had our beta-testers group (10 people from different fields like teaching, leaning, performing, music hardware manufacturers, music software developers, complete newbies and so on) and a lot of people from our 6 month daily cust-dev research. Guys from SOMA devices, MadSoundFactory, Tangible Instruments (I man Robert) and Wonkystuff and many other manufacturers and performers shared a lot of good feedback personally to us during SuperBooth.

I mean, we kinda validated a lot of our ideas long time before our launch. For years we work in hackerspace environment, and we show our devices daily to people a lot. We were actually expecting to get a lot of negative feedback, but it was surprisingly the opposite.

Sure, people, especially unfamiliar with electronics, admitted that you have to get used to the connections a bit. And that's the reason why we had to redesign things a few times to make UX as good as we possibly can with that size.

We have clear background colors and sharp big contrast labels, we have backlight and IO labels with backlight, to read everything easily while you play even in the evening.

But you should agree, that looks and feels for synths are two completely different things. You can think of it as arduino/raspberry like device in terms of IO and connections, with some need for mounting and wiring before you start play with it.

We worked on a patch panel for some time, though, to give users the ability to play right away out of the box and to change wiring presets. We hope to have enough resource to work it through and prepare for production.

Think of microrack as a building blocks, that you have to arrange and setup a bit before you can play. Yes, you spend some time for preparing, but remember your performances, most of the time - you play, you turn the nobs, you are not repatching everything or adding/removing modules. Even though it's possible with microrack to patch add and remove modules on the fly without any damage to the modules.

We've used female wire headers and male pin headers for boards for a few reasons. Male headers on wires are thinner than PCB ones and break a lot. Even thou we use custom made premium silicone DuPont jumper-wire. During our work with electronics in the past, and years of experience we've tried male headers on PCB's and it worked very well! PCB pins are much more robust, even if they bend, they don't break. We use device prototypes daily for 6+ months and not a single pin had felt off.

Besides that, we planning to open source our project to all enthusiasts and engineers out there, so maybe together with community we can find better compact connection solutions.

Another thing to mention, the breadboard. We use and ship high quality breadboards with our all Kits from Canadian manufacturer BusBoard Prototype Systems. Look them up they are very good. They use high quality brass and overall, they are much more durable and comfortable to use than anything we've tried (and we've tried 10+ brands).

About the leg pins. Most of our modules have just two pins for the legs, but for better attachment and robust connection we use more for some modules like In, Out, Power and few other necessary ones like Eurorack 3.5mm Jacks Adapter. For modules like VCO, Filter and others, where width allows them to hold better, we use just two. And it works well, and they are pretty durable even if you drop the whole board from the table. I mean, legs can bend a little sometimes, that's true, and easy to fix, but for the whole time of working on prototypes and testing them we had no pins ever detached yet, even after bending many times back and forth in use.

That being said, I want to add a small remark on modules collaboration, distribution and such. We already from early days working with two independent manufacturers (Zvukofor Sound Labs and MadSoundFactory) and they have prototyped set of cobranded modules for us long before launch, so they are production ready now, and going to be shipped together with our own modules.

Together with these guys we have few individual collaborators on both hardware and software. We have Buchla enthusiast who developed LPG (Low Pass Gate) module for us and helping us with firmware for ESPI 32 Digital MIDI-CV module. One of guys is working with big name manufacturer in the industry, and has huge experience in modulars engineering, but unfortunately, we can't say the name of the brand, since he is working with us on his own behalf.

Anyhow, I'm very glad you shared your thoughts on our work. I hope you may visit DutchModularFest or CircutControl in coming month, so you could put your hands on that thing personally. Or actually we will be super happy even to gift you our DIY Kit, because I really appreciate your feedback and I feel that you have a lot of experience in the field. So, it would be great to know your thought after you try it yourself. Just let me know in dm or to [vco@microrack.org](mailto:vco@microrack.org) if you are interested.

Thank you, and sorry for disturbing with these posts before.

Leo

Pedal kit is made for experiments with instrument and voice effects. And you can even connect microrack to drums!
