MegaZeux SFX player

Syntax

By default, notes play for ¹/₃₂ and in octave 3. You cannot go below octave 0 or above octave 6. Unrecognized characters are silently ignored.

C D E F G A B: Play the given note.
#: Raise the previous note by a semitone (i.e., sharpen it).
$: Lower the previous note by a semitone (i.e., flatten it).
0 1 2 3 4 5 6: Change the octave used for future notes.
+: Raise the octave by one.
-: Raise the octave by one.
X: Play a rest.
Z: Change the duration of future notes to ¹/₆₄.
T: Change the duration of future notes to ¹/₃₂.
S: Change the duration of future notes to ¹/₁₆.
I: Change the duration of future notes to ⅛.
Q: Change the duration of future notes to ¼.
H: Change the duration of future notes to ½.
W: Change the duration of future notes to 1.
.: Increase the duration of future notes to 1.5×.
!: Reduce the duration of future notes to ⅓×.
&: A special command for loading external files. Obviously it's not going to work very well here.
_: Used with & to indicate fallback when external files can't be loaded. Probably not interesting unless you're copying an SFX string from an actual MegaZeux game.
