Trying to scratch a soundfile with FLroller and table lookup.
I set the range of the roller to .6 because the wav is a little over
half the table size.
I realize my roller increments would be translated directly to
samples, meaning it's going to skip over a good bit, but I would still
expect more than two clicks. I also tried line and phasor as
commented out, and got no output. I also tried using filelen and
filesr in the header to determine roller steps, no output. Am I
misunderstanding something fundamental about table lookup?
