Continously play a soundfile from disk. This requires a buffer to
be preloaded with one buffer size of sound. The buffer size must
be a multiple of twice the synth block size. The default block size
is 64.
Note that disk-in reads the number of outputs to create from what
looks like an input, but it is not an input, and cannot be set
using a control.
