Fast Damping

When melody output stops, the D/A converter output

amplitude does not fall to zero instantaneously,

instead the output converges to zero within a maxi-

mum of 8.2 ms to prevent noise being generated.

Also, when one-shot melody output mode is retrig-

gered, melody output restarts after the fast damping

interval.
