Check many of my mc aware objects in else. Snake uses a perform routine, but a very simple one and you can also look for that copy function in the code. There is no real difference and you just have to split the vector in different chunks of block sizes to get different channels. Other vanilla objects that are mc aware also do this

I want to experiment with the new Pd feature of the
[snake_in~]/[snake_out~] objects, specifically with [snake_in~]. In Pd's
source files (in d_misc.c) I read the following in [snake_in~]'s dsp
routine:

```
static void snake_in_tilde_dsp(t_snake_in *x, t_signal **sp)
{
     int i;
         /* create an n-channel output signal. sp has n+1 elements. */
     signal_setmultiout(&sp[x->x_nchans], x->x_nchans);
         /* add n copy operations to the DSP chain, one from each input */
     for (i = 0; i < x->x_nchans; i++)
          dsp_add_copy(sp[i]->s_vec,
             sp[x->x_nchans]->s_vec + i * sp[0]->s_length, sp[0]->s_length);
}

```

There is no perform routine, so my question is, how do I deal with snake
signals in a perform routine? How do I unpack them? Where is this
happening in Pd's source code, so I can have a look?
