Thanks, Scott

I've had the same idea a while back, but it never got anywhere due to
lack of time. Still, I selected the part already: AD75019 16x16 analog
crosspoint switch matrix. I also designed a two layer board with the
Eagle freeware version for a 32x32 matrix made out of four IC (hence the
board is 100x80mm which is what this version is restricted to). This was
more an exercise to understand if I want to buy any of the other Eagle
versions, not a complete project. What's crucially missing is the
control board that loads the data for the switches, presumably acting
upon commands from MIDI and IO buffering. Depending on whether you want
to mix or distribute the signals you'd use different IO boards. If
there's interest, I can put up the Eagle project on the web.
