How about an analog out card for the I/O ports? 24ch on D-sub maybe? For the DM0 in a IEM rack with DX boxes on the stage.
This would be quite cool, but not very much space on an I/O card. I think the good solution for now is a SuperMADI card and a separate MADI converter. Ferrofish and SPL offer very good and cheap converters. Directout Andiamo 2.da for something a little more “roadready”.

very good idea for small rack solutions!
or an “DX64” with 32 in and 32 out in 1 RU
