string sbm="l35&2 g-2a+2g2f2e2d4d2c2d2a+4g4a+2g2c4c2a2c4c2a2c2a2g2f2e2f4d2c2";//这是由nok2phone把midi转换成的字符串，注意：l35&2后有空格，后边的的字符串的空格都删除了
system.out.println(sbm);
byte[] sendbinmsg=sbm.getbytes();
int a=0;
int b;
for (i=1; i<sendbinmsg.length; i++)
{
b=(int)sendbinmsg;
a=a^b;
}
byte xx=(byte)(a^0xff00);
int yy=(int)xx;
system.out.println("xx");
system.out.println(xx);
int ta;
ta=yy/16;
int tb;
tb=yy%16;
system.out.println("ta");
system.out.println(ta);
system.out.println("tb");
system.out.println(tb);
file://把ta tb加到sbm的最后就可以啦
file://sbm+&&+ta+tb
