To use a servo more than 15 controlled by maxuino

I recently try to use 20 servos in maxuino-009 patch. But, it dosen't allow me to control them over the 15 pin numbers. And then, I just checked the "maxuino.js" (maxuino-09/support/maxuin.js) that there is seem to be the problem in this program command i can guess.
this is following below;

function servoConfig(a, b, c) {
if (a<0) a = 0;
if (a>15) a = 15;
outlet(0, 112, a, b, c);

This is the reason why when changing the number of 16 pin, for instance, I always change value of 15 pin instead.

Please give me a piece of advice if anyone is genius of max & java.
if possible, I would really appreciate you.

Regards
