Ben This is a great idea
that of a VIM or video interface module...

Sign me up for a couple of those eh?

But then, I'll bet that that is exactly what most people think of
our beloved Analog music equipment as well!

The VIM is a fabulous idea though!

I think that some of the oscillators required might have to be working
up in a much much higher range than audio though...

Smiles!
