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.

maybe this could help you.

this is developed by winfried ritsch, who realised really fast
responding automated pianos with these.

Are you sure you need PWM pins? You'll definitely be paying for more

another
way to deliver a variable impulse to the hammers.

Hey guys,
I've had progress building an Arduino-powered solenoid system for a
controlling a piano's hammer mechanism (removing the keys) via pd.
So far I've found the solenoid I want to use. [image: Inline image

Does any one have experience daisy-chaining arduinos (or arduino
mega's)
to get more pwm pins, while using just one usb connection for
controlling
via pd?
