Can I change the channel configuration (to another mixer) myself?
Yes, but you will need to contact me for instructions on how to do so.

What’s the build quality like?
It’s important for me to disclaim what kind of operation this is. I am designing, coding, soldering, 3D printing, assembling and shipping these units out of my basement office when I’m not working as a freelance sound recordist. 3D printed objects can and will have some very minor cosmetic imperfections compared to the high end aluminum stuff we’re all used to.  I’ve taken some hi-res photos, so please take a closer look and decide for yourself. The TF6/TF8/T8 enclosure is made from carbon infused PETG which is strong, light weight, heat/UV resistant and pretty good looking for a 3D print, if I should say so myself. The encoders are nice smooth, stepless, silent and solidly wave soldered on to a PCB.

Will this work on my 6-series, 7-series, MixPre, Zoom recorder, etc ?
No, sorry – these units are only compatible with Sound Devices 8 series. You might be able to use it in your DAW though

Can I use this with a CL12 / LC8+ for trims?
Yes, there’s a version of the product for exactly that

How do I mount this thing in my bag?
The height of the unit is made so it can sit nicely above the XL-AES. I use double sided tape. Every mixer configuration is different, so you will probably have to get creative.

What if it breaks or stops working?
I am not running away if something breaks or stops working, please reach out to me if you run into any kind of issue:

What if Sound Devices stop supporting third party controllers in a future firmware?
I don’t see why that would happen. Third party support is an awesome feature of the 8 series mixer range, Sound Devices even promote this and other third party products on their own homepage. (Thank you Sound Devices!!)

I’ve heard third party controllers will sometimes act up and even cause 8 series to freeze
I’ve heard that too, and I am confident mine won’t act up. Here’s why: As someone who has spent quite some time interfacing with 8 series mixers, my guess is for Icon and Waves Fit boards, these connection issues / freezing / unresponsiveness issues is most likely caused by the bilateral midi communication needed in order for motorized faders, track naming data, SD Remote etc. all to work at the same time, while also being able to interface with a whole bunch of DAWs and other hardware/protocols. This is incredibly complicated stuff compared to what’s happening inside my controllers. Also, some of the boards like SL Mixface and Waves Fit (at least the ones I’ve tried) have some weird trim pot / encoder multiplication mismatches that don’t translate well to 8 series protocol implementation. I have not heard of any of these issues with CL16, CL12 and Sonosax LC8+ and guess what they don’t have motorized faders.

Anyway, my controllers are sending well tested, clear, uncomplicated one-way MIDI messages that are custom tailored to work smoothly with 8 series recorders specifically.
