I have  even trying to understand how to setup an ADI-8 QS so that it will route the third block of MADI data to the analogue out, and then route one analogue in back to the same block.

At 48k this works as described.

Buy at 96k I’m finding that I need to route multiple blocks - my sense is that at double speed perhaps the blocks are 4 inputs rather than 8 (perhaps for compatibility with ADAT).

Ideally I’d like the patch to work at both 48 and 96.

I have a work round just using block 1, but does anyone have any additional info about how the routing works at 96 (and even 192).
