Since this project is to have at least 42 knobs and a keyboard, I need to find a way to multiplex those inputs for use with the Teensy, which simply does not have enough analog pins for all that. I'm strongly considering the 74HC4067 analog multiplexer, but it is really hard to find a DIP socket version of it to breadboard, especially for any sort of reasonable price.

I'm also wondering if I might need to use a completely separate processor to handle the input stuff decently. My other project "Twister" might end up being a part of the NanoEgg after all...
