I think it could be advanced in a low tech way of providing more gates in a higher density. There are some that have 2 gates that have a selectable logic type, but these take up 5 hp and can cost $50-70 per gate. It seems like more simpler gates could fit in a smaller package in maybe 8 or 10 hp.
I am thinking of getting a small case with som modules to complement my other gear (pedals, 0-coast, Zoias). For me small cases or boards of pedals is the way to go. I dont want a rooms filled with racks
