while i didn't follow it from the beginning of it's concept or aimpad's idea, at this moment it make sense that it only works for linear since it seems that it uses either distance or pressure to measure (just guessing here).
nevertheless, this tech caught my interest and i would be very excited to try this out on racing games!
oh boy, you don't want to do that so soon do you?
changing mx switches on your shine 4 would mean you have to open up the keyboard and desolder the switches and replace them with mx red switch.

my recommendation, try playing o2jam with blue switch, you might like it.
or buy another keyboard with mx red switch. <- i'm serious about this recommendation.
