getTailSize

Reports to the DAW the length of the tail your plugin makes (in samples).

For instance, if you're making a reverb or delay with a 1-second tail, the corresponding value in samples would be 48000 or 96000, depending on the sample rate.

If your plugin is a tone generator or a synthesizer, set this value to -1 (indicating that your tail can be infinite).

In situations where your plugin doesn't leave a tail, you can either omit this function or return 0.
