[microsound] Arduino Chip

[Jaime Munarriz Ortiz]

I've connected it to my MS20, sending CV to control pitch from Processing.
But it doesn't output real voltage changes, it makes pulse width 
modulation so the average voltage is more or less.
The signal is blocky , a kind of square wave. I think it could be used 
to control a transistor wich could trasmit a smooth voltage control 
signal, but I haven't tested it.
You can also use it as a MIDI interface. But it is better suited to 
control sensors and other physical input information. So you can build a 
new controller instrument, connected to Pd or Midi or Max or Osc or...
