Computerized patching

[David Halliday (Volt Computer)]

There are a family of chips which do just this - called CrossPoint
switches.  They are used extensively in telephone and video switching.
Because their market share is fairly small, they are expensive but they
look as through they would do exactly what you are looking for.

The problem here is that if you want to be able to hook everything into
everything else on a programmable basis, you are talking about a
*H*U*G*E* array of switches and patch cords...

Even if you normalize most of the common connections ( VCO into VCF into
VCA ), you are still going to have several cords per modular function.
Each input function and each output function will need their own rail on
the switch so adding one input will actually add one switch for each of
your outputs.
