[sdiy] What type of switch would this be?

[Jeff Farr]

I need to be able to connect to any number of inputs at a time. At this
moment I have no spec for what unconnected outputs must be, but I believe
they will have to float. Mind you this is for analog signals, not digital.
The purpose of this being a switch matrix to route CV signals around a
synth.
