Thanks, I got all the info I need. Now I'm running into this strange error, by using the following line in the setup function:

```
var_io_snake_tilde_class = class_new(gensym("var_io_snake~"), (t_newmethod)var_io_snake_tilde_new,  (t_method)var_io_snake_tilde_free, sizeof(t_var_io_snake_tilde), CLASS_MULTICHANNEL, A_DEFFLOAT, 0);
```

The error is the following:

```
var_io_snake~.c:85:82: error: ‘CLASS_MULTICHANNEL’ undeclared (first use in this function)
   85 |                 (t_method)var_io_snake_tilde_free, sizeof(t_var_io_snake_tilde), CLASS_MULTICHANNEL, A_DEFFLOAT, 0);

```

I'm #including m_pd.h (I mean, it's finding the rest of the Pd API stuff I'm using there), and CLASS_MULTICHANNEL is in that file, so why do I get this error?
