[PD] soundfiler is slow; readsf~ no filelength

[Samuel Burt]

I installed a new version of gridflow. I'm happy to say it is so much easier to do than it used to be.

Gridflow is giving me this message: 
error: method 'endian' not found for inlet 0 in class '#io.grid'

When I search for the error, Pd goes here:

It highlights the receiving of $0-placeholder. Any idea why?

It isn't giving me the number of samples, yet. It just prints the error and outputs 0.
