RAM -Sounds contained in the Block housing
the Song. If there is not sufficient memory in RAM
for the operation, the Song will play incorrectly
using ROM-Sounds.
Hint: When the samples of a Song are loaded,
the Auto Preload utilizes the free Sample-RAM,
then starts to substitute the samples of the Song in
playback with the samples of the new Song. At a
certain point, the Song in playback will start to play
incorrectly. It is advisable, therefore, to avoid using
an excessive amount of samples (not more than
half the available Sample-RAM).
