Hi...
It's not really the subject because we didn't use Pd for the this
version...
But we've done a piano player with 48 servo engine (HS-422 from Hitec)
controlled by I2C with a 3 PCA9685 and a Raspberry Pi.
This one from Adafruit ( http://www.adafruit.com/products/815 ) can be
used with an Arduino.
