[PD-dev] Object crashes when trying to write to its outlet

Getting back here after a while, just to confirm that Christof was
right. I would like to clarify if the following chunk is necessary to be
placed in the dsp routine:
```
t_sample **dummy = x->in;
for (i = 0; i < x->inchnls; i++)
*dummy++ = sp[i]->s_vec;
dummy = x->out;
for (i = x->inchnls; i < x->inchnls+x->outchnls; i++)
*dummy++ = sp[i]->s_vec;
```
Without this the object crashes. From what I understand, the sp pointer
contains the input and output samples, together with the block size,
right? So, it's necessary to write the input and output to the pointer
of pointers for the inlets and outlets.
Anyway, thanks for the help.
