hi dave!
check out the dsp_addv function, I think it’s meant for exactly this. I don’t
have any code right in front of me… oh wait, I do … I’m pretty sure this works:
void grans_dsp(t_grans *x, t_signal **sp)
{
int num = x->numinlets + x->numoutlets;
t_int **w = x->w;
w[0] = (t_int *)x;
w[1] = (t_int *)sp[0]->s_n;
int i;
for (i = 0; i < num; i++) {
w[i+2] = (t_int *)sp[i]->s_vec;
}
dsp_addv(grans_perform, num+2, (t_int *)w);
}
hope that’s useful!
cheers,
rama
