mechanical music

Started by Corey Fogarty October 30, 2003
I have a great device that helps me tune my guitar, I would like to
use such a device to control the movement of motors/servos. I am
assuming there is a chip out there that will take a key and turn it
into a number or range of numbers that I could detect and then use to
set the speed, direction and duration of motor movement.

I would then like to detect tempo in some way, rhythm, perhaps
changes in pitch or volume, such that strumming an E cord three times
would cause a motor to turn three revolutions. Even adjust speed,
the faster I strum the faster the motor goes.

Any help would be greatly appreciated.

Thanks in advance,
