Keyboard Encoder

[Hugo Haesaert]

Hi Jim n All !

I recall reading an article in Computer Music Journal (early '90s) 
from a french team, where each key got some flat coil, moving between 
two stationary coils, operating as a linear motor .  They were big, 
but narrow, so they could be stacked to form the kbd .  The idea was 
to give "force feedback" to the player and give meaningful input to 
the using system .  

This spells loads of power, cores and copper : heavy and expensive .

Never saw anything, or heard, of it again .

Cheers .


Keep 'em oscillating :)
