Is SOUND synchronous or asynchronous ?

[CharlieJV]

I'm having a devil of a time getting that straight in my head.

`SOUND` waits for the duration of the sound, so it's synchronous. Note however that if you use `PLAY "MB"` at some point to play sounds in the background that also impacts `SOUND` commands, so it's possible to have them play in the background (potentially by accident). That behavior was recently fixed in QB64-PE v3.2.0, so if you use a version older than that `SOUND` won't respect the `PLAY "MB"` setting and will always wait for the sound to finish.

Let's see if I get it.

SOUND is asynchronous in the sense that a SOUND statement does not cause the entire program to pause until the statement finishes.

SOUND is synchronous in the sense that a SOUND statement cannot start until a previous SOUND statement completes.

Is that right?  Both asynchronous AND synchronous?
