Yes, the raspberry pi is tinker friendly.
Have been reading about small form factor computers a lot, even purchased the cubox 4 pro or what's it called, a few years back. It's not powerful enough for my needs.
Maybe in 5 years the latest and greatest rpi or equivalent will be as powerful as a proper desktop computer from 2016, that would be good.

Turns out you can choose tcp/ip as interface in Sigma studio instead of USB.

And there is code for Linux available.

Meaning that you can use let the raspberry pi be the interface and your laptop will not be tied down to the board via a USB cable.

Also saves $, even tough the raspberry has a price of course, but hard (not clever) to avoid that cost.

You could also go to an arduino or stm32 microcontroller for about a single USD on ebay for the great clones. Steep learning curve if you are not at all familiar with embedded programming though. They are similar to the raspberry pi in that there is a huge community of people building with them. There are tons of add on boards that plug together like $3 2.5" touch screens for a user interface. I plan to do the arduino route since that is what I have laying around, and it should allow me another fun open source project for others to build on top of as well.

I removed the 2pcs AD1939 codecs from main board and made a separeta I/O board.
So I can put them vertical to the back of the cabinet.
Enables me to populate as many as i want and use different I/O combinations.

made a vertical pcb with 1 pcs AD1939
4 inputs at the "top"
8 outputs at the "bottom"

I really like the look of that! So clean and tidy.
Only missing volume control now, but that is not so important.

Volume control you do in the ADAU1467.

Or in the ad1939 (but I can't see why you would do that)

This is all digital.

Maybe you refer to the human machine interface
HMI

Thats a topic....

But a rotatry knob on the front I guess is minimum.
A display.

split interfaces from DSP
DSP is now 100x100mm.

Interfaces externally support up to 48ch out. 24ch in using AD1939 codecs.

Ready for production.

Yes, I was thinking of the HMI.
A volume knob and an input selector and this thing is complete.
