Foreground/Background Operation
Operation Action
MF Sets music (PLAY statement) and SOUND to run in the
foreground. That is, each subsequent note or sound will
not start until the previous note or sound has finished.
This is the default setting.
MB Music (PLAY statement) and SOUND are set to run in the
background. That is, each note or sound is placed in a
buffer, allowing the BASIC program to continue executing
while the note or sound plays in the background. The
maximum number of notes that can be played in the
background at one time is 32.
