[sdiy] Which programable chip?

[lightburnx at yahoo.com]

They have larger analog switches, like so, a 16 x 16 (ones larger still exist as well):

http://www.analog.com/en/switchesmultiplexers/analog-crosspoint-switches/ad75019/products/product.html

Runs on a serial interface.

Is this just going from point A to point B shuffling though inputs, or more more complex sequencing?
