I did play with controlling the RTX from within MATAA (autoscaling etc.), and it's possible. However I preferred to work the switches with my fingers for real-world work with MATAA.

The HID works both ways. You can monitor settings or take over the control of the settings from the PC. An LED on the front panel indicates when the settings are controlled remotely (from the PC).
There are no plans to change this.

I was hoping you could tell us about "much better chip" then AK5394, used in RTX.

(And, BTW, which is obsolete and is not manufactured now )

I agree. The AK5394A is a very good ADC. A pity that it is obsolete. I do have access to a reasonable quantity though

The RTX6001 will stay independent of the software.

Just to clarify - is/was Virtins a reseller or did they perhaps take over the production under license?
Virtins got a possibility to resell the RTX6001. Unfortunately that is no longer possible as described earlier.

But who knows? Perhaps there will be a way forward after all?

I did. It looks promising, but it has been held back by other things, so there are still some tests to do.

Thanks to RTX for cooperating with the DIY community and making this product. I find it extremely useful in my work. Like most people I don't need the best SOTA, but I need pretty damn good SOTA and always admire the pursuit of it and its realization.

and yes, it does sound pretty damn good as well as measure well.

Cheers
Alan
