[sdiy] Hardware convolution box?

[cheater00 cheater00]

I assumed as much - that's why I think a convolution box should be within
reach of even a novice dev. What about libraries for: reading off sd card
or usb stick; using data structures like ring buffers; driving lcds; text
driven menu uis; scanning front panels... is this sort of stuff available?
