Many mixer manufacturers went down this rabbit hole. I guess it was a financial debacle for most of them.
I was somewhat involved in the design of Soundcraft's take on the subject, which never saw the light of day.
I wonder how many of these hybrid mixers remain in existence today...
Yes. Dick Swettenham was "looking after" the assets from the Novation development (not the keyboard people) for the relevant bank/creditors in the 90s after the finances on that went bad. We ended up taking it into P&G and got it up and running to an extent internally. I recall bringing the kit up from Bristol to P&G in Blackwood in the company LWB Transit van that steered like a boat

IIRC level control etc was mainly realised with MDAC in the feedback arm around opamps. Zero Crossing detect to minimise the dreaded zipper noise.
