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.
