I've no idea what your trying to do cos I missed the original post, but
just FYI, you will generally be better off doing x[i] rather than *x and
incrementing x. Modern C compilers (eg. gcc 4) can vectorise array
operations as long as you dont obfuscate them with pointer maths.

Could someone please help with this apparently
simple problem?
I'm not a "professional" either, but this is what I do:
unsigned int TLData::MixChannels(float *A, float *B, float* out,
unsigned int count)
/*Mix function for (-1)-(1) float audio*/
{
unsigned int i;
float *p_output = out;
float *p_A = A;
float *p_B = B;
for ( i=count; i > 0;i--){
if (*p_A<0 && *p_B<0) {
*p_output =(*p_A+1)*(*p_B+1)-1;
} else {
*p_output =2*(*p_A+*p_B+2)-(*p_A+1)*(*p_B+1)-3;
}
p_output++;
p_A++;
p_B++;
}
return count;
}
