Added velocity scaling

[skutamac]

Added Velocity scaling for each piezo to change how the velocity
responds to how hard you hit the pads.

If the scaling value is set below 100 then you have to hit the pad harder to reach maximum velocity. This enables a greater control of the velocity from soft touches to really hard hits.
Also if you want less sensitivity then increase the scaling above 100 to make the velocity max out with soft hits. This will help with beginners and kids where the velocity can be made to max out even with soft hits on the edge of the pads.

Scaling can be done on a per pad basis.

P.S. This is my first fork and Pull request using GitHub.

How can i add more drums into your code with velocity?

Hi, Nice update but you missed out :-

unsigned short velScale[NUM_PIEZOS];

Regards,

Whenever i copy and paste the code i get a couple error reading.. what should i do?
